How to use Programmable resistance 2720

Hello,
I am using and programming with PXI-2720. Could I set the resistance value in CVI program?
I put the niswitch.fp in my project.  
Do I need to control all relays for making 30ohm( example value) at my program?
Could you help me if you have any sample codes or references?
I have used "272x Reference VIs" for LabView.
I am looking for similar instrument driver for CVI.
Thank you,
Insuk

    In the labview\resource\appbuild folder their are some VI's that can deal with build specs! They return a variant containing the data!
    It's the reason I build a variant probe.
    Be aware that the build info is not present in th lvproj file of the built executable!

  • How to use macro's functionality in a programe...?

    hi,
    i am siva,
    i am new to abap,
    i am not having clarity on how to use macro in a programe,
    please send me any source code of a programe which
    contain functionality of macros..?
    and explain functionality of macros...?
    i any of u know answer..
    please send me source code of a programe that use macros...?
    reguars,
    siva.

    Hi,
    <u>Macros:</u>
    If you want to reuse the same set of statements more than once in a program, you can include
    them in a macro. For example, this can be useful for long calculations or complex WRITE
    statements. You can only use a macro within the program in which it is defined, and it can only
    be called in lines of the program following its definition.
    The following statement block defines a macro <macro>:
    DEFINE <macro>.
    <statements>
    END-OF-DEFINITION.
    You must specify complete statements between DEFINE and END-OF-DEFINITION. These
    statements can contain up to nine placeholders (&1, &2, ..., &9). You must define the macro
    before the point in the program at which you want to use it.
    Macros do not belong to the definition part of the program. This means that the DEFINE...ENDOF-
    DEFINITION block is not interpreted before the processing blocks in the program. At the
    same time, however, macros are not operational statements that are executed within a
    processing block at runtime. When the program is generated, macro definitions are not taken
    into account at the point at which they are defined. For this reason, they do not appear in the
    overview of the structure of ABAP programs [Page 44].
    A macro definition inserts a form of shortcut at any point in a program and can be used at any
    subsequent point in the program. As the programmer, you must ensure that the macro
    definition occurs in the program before the macro itself is used. Particular care is required if you
    use both macros and include programs, since not all include programs are included in the syntax
    check (exception: TOP include).
    To use a macro, use the following form:
    <macro> [<p1> <p2> ... <p9>].
    When the program is generated, the system replaces <macro> by the defined statements and
    each placeholder &i by the parameter <pi>. You can use macros within macros. However, a
    macro cannot call itself.
    Ex:
    DATA: RESULT TYPE I,
    N1 TYPE I VALUE 5,
    N2 TYPE I VALUE 6.
    DEFINE OPERATION.
    RESULT = &1 &2 &3.
    OUTPUT &1 &2 &3 RESULT.
    END-OF-DEFINITION.
    DEFINE OUTPUT.
    WRITE: / 'The result of &1 &2 &3 is', &4.
    END-OF-DEFINITION.
    OPERATION 4 + 3.
    OPERATION 2 ** 7.
    OPERATION N2 - N1.
    The produces the following output:
    The result of 4 + 3 is 7
    The result of 2 ** 7 is 128
    The result of N2 - N1 is 1
    Here, two macros, OPERATION and OUTPUT, are defined. OUTPUT is nested in
    OPERATION. OPERATION is called three times with different parameters. Note how
    the placeholders &1, &2, ... are replaced in the macros.

  • How to use the method calendar.getTimeInMillis() and setTimeInMillis(bb)

    I have met some problems in writing my programme,I want to know what the time is after every 20 minutes so have written some codes as below ,but the compilar warned me that there are some errors in them ,and I don't know how to use them correctly ,can you help me?
    Thank you very much!
    the code is:
    begin=datime+" 00:00:00";
    Calendar calendar=Calendar.getInstance();
    DateFormat df = DateFormat.getDateInstance();
    Date start=df.parse(begin);
    calendar.setTime(start);
    long aa=calendar.getTimeInMillis();
    calendar.setTimeInMillis(aa);

    Hopefully the following snippet of code will help you out (note that the Date class seems more appropriate for what you need to do):
    import java.util.*;
    import java.text.*;
          String begin="00:00:00";
          SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss");
          df.setTimeZone(TimeZone.getTimeZone("GMT"));
          Date start=new Date();
          try {
             start=df.parse(begin);
          } catch (Throwable e) {
             System.out.println("Invalid time format");
          long aa=start.getTime();   // to get the time in milliseconds
          System.out.println(aa);    // just to see what the answer is (should be zero)
          start.setTime(aa);         // to set the time in milliseconds

  • How to use abap debugger and se80

    can any body give easy deatils about it?

    Hi
    Debugger
    This section of the ABAP Workbench documentation provides information on how to use the Debugger as a test tool for finding errors in the source code of an ABAP program.
    Functional Overview
    Use
    The ABAP Debugger is an integrated test tool within the ABAP Workbench. You use it to check the program logic and to find errors in the source code of an ABAP program. In the Debugger, you can step through the source code of a program. The running program is interrupted after each step, allowing you to check its processing logic and the results of individual statements.
    As of Release 6.10, you can also run Business Server Pages (BSP) in the debugging mode. You can also display and set breakpoints here. Business Server Pages can be displayed in the Object Navigator when you select an appropriate application under BSP Application.
    Features
    The Debugger provides an efficient means of identifying errors in ABAP programs. It contains the following functions:
    Ways of starting the Debugger
    Choosing different views
    Choosing different execution options in the Debugger
    Displaying source code in the Debugger
    • Setting and deleting breakpoints
    • Setting and deleting watchpoints
    • Stopping a program at a particular statement or event
    Displaying and changing field contents at runtime
    Displaying ABAP Objects and references
    Displaying and positioning strings
    Setting and deleting database locks
    Opening the ABAP Editor, or Object Navigator
    System settings and runtime warnings
    Starting the Debugger
    There are two possible strategies for starting the Debugger in the ABAP Workbench:
    By setting breakpoints then running the program
    By running the program in debugging mode.
    Setting Breakpoints
    A breakpoint is a signal in a specific line of the program source code. This signal indicates to the ABAP runtime processor to stop the program at the relevant line and start the ABAP Debugger. A distinction is made between static and dynamic breakpoints. For further information about the different types of breakpoints and how to use them, refer to Breakpoints.
    Direct Processing
    You can start the Debugger without previously having set breakpoints. This is the best procedure to use when you want to test a program right from the beginning. It is also a useful procedure if you are not overly familiar with the program and therefore are not sure where best to set breakpoints. You can start the Debugger as follows:
    From the Object Navigator
    Select a report or transaction and choose Program ® Test ® Debugging.
    From the ABAP Editor
    Choose Program ® Execute ® Debugging (or the Debugging pushbutton).
    From any screen
    Choose System ® Utilities ® Debug ABAP.
    From any screen
    Enter /h in the command field.
    Display Modes in the Debugger
    When you are debugging a program, there are various display modes that you can use. All of the display modes have the same structure. The top part of the screen displays an extract of the program source code. The bottom part displays the information specifically available in that display mode. There are also pushbuttons on the screen allowing you to switch to the most frequently-used display modes.
    Display Modes Available Using Pushbuttons
    Fields
    The scrollable field display contains the contents of up to eight fields. The contents of the three most important system fields are always displayed. This is the default display mode in the Debugger. See also Processing Fields
    Table
    Displays the contents of an internal table. This mode allows you to display and edit the entries in an internal table. See also Processing Internal Tables
    Breakpoints
    A scrollable display containing up to 30 breakpoints. Next to each breakpoint is a counter. You can also delete breakpoints in this display. See also Managing Dynamic Breakpoints
    Watchpoints
    You can set a watchpoint for a field so that the program is interrupted whenever the value of that field changes. This display mode contains a list of watchpoints, the fields and programs to which they are assigned, the current values of the fields, and the conditions upon which the watchpoint is activated. See also Setting Watchpoints
    Calls
    This mode displays the current sequence of events, and the sequence of calls up to the current breakpoint. The last active call is displayed at the top of the list; previous calls are listed in reverse chronological order. When an event (for example, START-OF-SELECTION) concludes, it is deleted from the display.
    Overview
    This mode displays the structure of the program. It lists its events, subroutines, and modules, and shows which sections belong to which events. It also displays the section currently being processed.
    Settings
    This mode displays the current Debugger settings. You can change the settings by selecting or deselecting various options. For further information, refer to Settings and Warnings
    Other Display Modes
    You can access other display modes by choosing Goto ® Display data object.
    Single field
    Displays the contents and technical attributes of a field.
    Structured
    field
    Displays the components of a structure, along with their contents and attributes. If you double-click a component, the system displays detailed information for it.
    Strings
    Display the content and current length of the string. You can also display part of the content by means of offset and length.
    Internal table
    Displays the type, line numbers and contents of an internal table.
    Object
    Displays the structure of an ABAP Object.
    For further information on these displays, refer to Displaying Attributes and Displaying ABAP Objects
    Checking System Programs for Errors
    To check a program or program component that is part of the ABAP Workbench (for example, the Screen Painter), you must use the system Debugger. To start the system Debugger, choose System ® Utilities ® Debug System from any screen. To stop the system Debugger, choose Debugger ® Debugging off.
    Displaying Program Attributes
    You can display the attributes Fixed Point Arithmetic, System Program, and Unicode Checks of the program that has just been executed by choosing Goto ® Further Information ® Program Attributes.
    Restarting the Debugger
    If you choose Debugging ® Restart, debugging mode is stopped and the system takes you to the initial screen of the last transaction you called. If, for example, you started an ABAP program in debugging mode from transaction SE38 (ABAP Editor), choosing Debugging ® Restart will take you back to the screen titled ABAP Editor: Initial Screen. If you want to restart the program in debugging mode, choose Debugging.
    Breakpoints
    Apart from direct execution of an ABAP program in the Debugger, it is also possible to start the Debugger call by the exact setting of a breakpoint. This is achieved by setting one or more of these breakpoints in the program. A breakpoint is a signal at a particular point in the program that tells the ABAP runtime processor to interrupt processing and start the Debugger. The program runs normally until the breakpoint is reached.
    There is also a special kind of breakpoint called a watchpoint. When you use watchpoints, the Debugger is not activated until the contents of a particular field change. For further information, refer to Watchpoints.
    Breakpoint Variants
    The Debugger contains different breakpoint variants:
    Static
    The BREAK-POINT statement in an ABAP program. Static breakpoints are not normally user-specific. However, you can make them user-specific.
    Directly-set
    dynamic breakpoints
    Can be set in the ABAP Editor or the Debugger. Dynamic breakpoints are always user-specific, and are deleted when you log off from the R/3 System.
    Breakpoints
    at statement
    The Debugger stops the program directly before the specified statement is executed.
    Breakpoints
    at subroutine
    The Debugger stops the program directly before the specified subroutine is called.
    Breakpoint at function module
    The Debugger stops the program directly before the specified function module is called.
    Breakpoint at method
    The Debugger stops the program directly before the specified method is called.
    Breakpoints at system exceptions
    The Debugger stops the program directly after a system exception, that is, after a runtime error has been intercepted.
    Static Breakpoints
    Static breakpoints are not normally user-specific. Once a user has inserted the statement BREAK-POINT or BREAK name in an ABAP program, the system always interrupts the program at that point for that user or only for the user name. This procedure is only useful in the development phase of an application, when the program execution is always to be interrupted at the same place. For further information, refer to Static Breakpoints.
    In HTTP sessions, a static breakpoint is skipped if you did not set additional dynamic HTTP breakpoints in the editor of a BSP page. Instead, a corresponding system log entry is written, which can be checked using transaction SM21.
    Dynamic Breakpoints
    Dynamic breakpoints are user-specific. Therefore, you should use them if you only want the program to be interrupted when you run it yourself, not when it is being executed by other users. All dynamic breakpoints are deleted when you log off from the R/3 System.
    Dynamic breakpoints are more flexible than static breakpoints, because you can deactivate or delete them at runtime. They have the following advantages:
    You do not have to change the program code
    You can set them even when the program is locked by another programmer
    You can define a counter that only activates the breakpoint after it has been reached
    Special dynamic breakpoints are useful when you want to interrupt a program directly before a particular ABAP statement, a subroutine, or an event, but do not know exactly where to find it in the source code. Event here is used to refer to the occurrence of a particular statement, for example, or calling up a method. Special dynamic breakpoints are user-specific. You can only set them in the Debugger. For further information, refer to Dynamic Breakpoints.
    In HTTP sessions, the system stops both at static and dynamic breakpoints if a dynamic breakpoint was set in the editor of a BSP page before program execution.
    Lifetime and Transfer of Breakpoints
    A static breakpoint remains intact as long as the BREAK-POINT or BREAK-POINT name statement is not removed from the source code. Without saving, dynamic breakpoints only remain intact in the relevant internal session. However, they are effective during the entire user session, if they are saved by choosing Breakpoints ® Save in the ABAP Debugger. For more details on the subject of sessions and user sessions, refer to Modularization Techniques in the ABAP keyword documentation.
    If you call an HTTP session during a user session, only the HTTP breakpoints are loaded when the HTTP session is started. You activate HTTP debugging in the ABAP Editor by choosing Utilities ® Settings ® HTTP Debugging. Depending on the setting, the system then displays either the HTTP or standard breakpoints in the Editor.
    If you call an update session during a user session, breakpoints that were defined beforehand in the calling processing unit are copied to the new update session, where they can be displayed under Breakpoints. If, in the ABAP Debugger, you check Update Debugging under Settings and then, for example, call the update module func using CALL FUNCTION func IN UPDATE TASK, a new window is opened in which you can debug this function module in the update session. All the breakpoints that were set in the calling processing unit can also be processed here.
    Breakpoints at Statements
    You can use this special kind of dynamic breakpoint to interrupt a program directly before an ABAP statement is processed.
    Prerequisites
    You must already be running the program in the Debugger.
    Procedure
    To set a breakpoint at an ABAP statement:
    1.Choose Breakpoint ® Breakpoint at ® Statement...
    The following dialog box appears:
    2.Enter the ABAP statement.
    The system sets a breakpoint at all points in the program at which the ABAP statement occurs.
    3.Choose ENTER.
    The breakpoint applies to all lines containing the specified statement.
    Result
    The system confirms the breakpoint and adds it to the list in the display. When you finish your debugging session, the breakpoint is automatically deleted unless you have explicitly saved it.
    Breakpoints at Subroutines
    You can use this special kind of dynamic breakpoint to interrupt a program directly before a subroutine is called.
    Prerequisites
    You must already be running the program in the Debugger.
    Procedure
    To set a breakpoint for a subroutine:
    Choose Breakpoint ® Breakpoint at ® Event/Subroutine.
    The following dialog box then appears:
    Enter the name of the subroutine before which you want to interrupt the program. By default, the Program field contains the name of the program that is currently active. The system sets a breakpoint wherever the specified subroutine occurs in the program code.
    Choose ENTER.
    Result
    The system confirms the breakpoint. The breakpoint is added to the breakpoints displayed.
    Breakpoints at Function Module
    You can use this kind of dynamic breakpoint to interrupt a program directly before a function module is called.
    Prerequisites
    You must already be running the program in the Debugger.
    Procedure
    To set a breakpoint for a function module:
    Choose Breakpoint ® Breakpoint at ® Function module...
    The following dialog box appears:
    Enter the name of the function module before which you want to interrupt the program. The system sets a breakpoint wherever the specified event, module pool, or subroutine occurs in the program code.
    Choose ENTER.
    Result
    If you entered a valid function module name, the system confirms that the breakpoint has been set. If the function module exists in the system, the new breakpoint is added to the display list.
    Breakpoints at Methods
    You can use this special kind of dynamic breakpoint to interrupt a program directly before a method is called.
    Prerequisites
    You must be already running the program in the debugger.
    Procedure
    To set a breakpoint for methods:
    1. Choose Breakpoint ® Breakpoint at ® Method...
    The following dialog box then appears:
    2. Enter the name of the method and class before which you want to interrupt the program. A breakpoint is then set each time the specified processing block appears in the source code.
    3. Choose ENTER.
    Result
    The system confirms the breakpoint. The breakpoint is added to the list in the display.
    Breakpoints at System Exceptions
    You can use this special form of dynamic breakpoint to interrupt a program immediately after a runtime error has occurred.
    Prerequisites
    You must already be running the program in the Debugger.
    Procedure
    To set a breakpoint at a system exception:
    Choose Breakpoint ® Breakpoint at ® System exception.
    Result
    The system confirms the breakpoint. The breakpoint is added to the breakpoints displayed.
    When a system exception is triggered, a warning triangle appears in the line containing the statement that caused it. If you double-click the warning triangle, the internal name of the runtime error appears.
    Static Breakpoints
    You should only use static breakpoints during the development phase of an application. You must remove them from your program before you transport it.
    Setting Breakpoints
    To set a static breakpoint, use the ABAP statement BREAK-POINT . Place the breakpoint in the line at which you want to interrupt the program.
    program RSDEBUG_01.
    if SY-SUBRC 0.
    break-point.
    endif.
    When you run the program, the runtime processor interrupts it when the breakpoints occur. You can number your breakpoints to make them easier to identify ( BREAK-POINT 1, BREAK-POINT 2 …).
    Static breakpoints are not normally user-specific. The program is, therefore, always interrupted as soon as the runtime processor reaches the line containing the breakpoint. The program is interrupted regardless of the user who executes it.
    However, you can set user-specific static breakpoints using the BREAK statement followed by your user name. For example, if you use the statement BREAK SMITH , the program is only interrupted when user Smith runs it. Although user-specific breakpoints appear in the program code, they are not active when other users run the program. You should, however, be careful if an application is being used by several users with the same name.
    Deleting Breakpoints
    Since static breakpoints apply to all users, you must remove them from the program once you have finished testing it. In the ABAP Editor, you can find breakpoints quickly by choosing Utilities ® Global search. You can also use the Extended Program Check to find them.
    If you do not remove static breakpoints from your program, they will be transported to your production system. This could cause serious problems in the production system.
    Dynamic Breakpoints
    You can set up to 30 dynamic breakpoints without changing the program code. Dynamic breakpoints can be set either in the ABAP Editor or directly in the Debugger.
    Setting Dynamic Breakpoints in the ABAP Editor
    You can set dynamic breakpoints in the ABAP Editor regardless of whether you are in display or change mode. You can also set breakpoints directly from within the Debugger at runtime. To set a dynamic breakpoint in the ABAP Editor:
    Position the cursor on the line of the source code at which you want to set the breakpoint.
    Choose Utilities ® Breakpoints ® Set or the Stop icon. The system confirms that the breakpoint has been set.
    To display a list of all dynamic breakpoints in a program, choose Utilities ® Breakpoints ® Display. You can use this list to navigate to a particular breakpoint or to delete one or more breakpoints from the program.
    Setting Dynamic Breakpoints in Debugging Mode
    To set a dynamic breakpoint in the Debugger:
    Position the cursor on the line in which you want to set the breakpoint.
    Select the line by double-clicking it or choosing Breakpoint ® Set/delete.
    The system sets the breakpoint, and displays a small stop sign to the left of the relevant line. If the line already contained a breakpoint, it is deleted.
    When you finish your debugging session, the breakpoint is automatically deleted unless you have explicitly saved it.
    Saving Breakpoints
    If you want to leave the Debugger temporarily, you can save your dynamic breakpoints so that they are still active when you return to the Debugger within the same terminal session.
    To save the breakpoints that you have set in the Debugger:
    Choose Breakpoint ® Save.
    The system saves all of the breakpoints that you have set in the current program. These breakpoints will remain active until you either explicitly delete them or log off from the system.
    You can also delete breakpoints that you have saved:
    By deleting individual breakpoints from the display and then saving again. In this case, only your selected breakpoints will be deleted.
    By choosing Breakpoint ® Delete all. In this case, the system deletes all dynamic breakpoints.
    Managing Dynamic Breakpoints
    The ABAP Debugger provides a convenient user interface for managing breakpoints. To open the breakpoint display, choose Breakpoints, or, from the menu, Goto ® Control debugging ® Breakpoints.
    Example
    Functions
    This display mode contains the following functions for breakpoints:
    Breakpoint Display
    The scrollable breakpoint display contains up to 30 dynamic breakpoints. For breakpoints that you set directly, the program name and line number at which the breakpoint occurs are displayed. For special breakpoint forms, the list displays the statements, events, subroutines, and module calls at which the relevant breakpoints are set.
    Counter
    In the breakpoint display, you can specify a counter. When you use a counter, the breakpoint is not activated until it has been reached a specified number of times. For example, if you enter 5 for the counter, the breakpoint is not activated until it is reached for the fifth time. After the breakpoint has been activated, it remains so, and the counter no longer appears in the breakpoint display.
    Deleting Breakpoints
    Position the cursor on the breakpoint that you want to delete, and either double-click the line or choose Breakpoint ® Set/delete. To delete all breakpoints, choose Breakpoint ® Delete all.
    Activating and Deactivating Breakpoints
    Position the cursor on the breakpoint that you want to activate or deactivate and choose Breakpoint ® Activate/deactivate.
    Watchpoints
    Like a breakpoint, a watchpoint is an indicator in a program that tells the ABAP runtime processor to interrupt the program at a particular point. Unlike breakpoints, however, watchpoints are not activated until the contents of a specified field change. Watchpoints, like dynamic breakpoints, are user-specific, and so do not affect other users running the same program. You can only define watchpoints in the Debugger.
    Use
    You set watchpoints in the Debugger to monitor the contents of specific fields. They inform you when the value of a field changes. When the value changes, the Debugger interrupts the program.
    Features
    You can set up to five watchpoints in a program.
    See also Setting Watchpoints.
    You can also specify the conditions on which a watchpoint is to become active.
    You can specify logical conditions between up to five conditional watchpoints.
    See Specifying a Logical Expression.
    You can define watchpoints as either local or global. If you define a global watchpoint, it is active in all called programs. Local watchpoints are only active in the specified program.
    You can change and delete watchpoints.
    See Changing Watchpoints.
    You can use watchpoints to display changes to the references of strings, data and object references, and internal tables.
    See Memory Monitoring with Watchpoints
    Setting Watchpoints
    If you want to interrupt a program when the contents of a field or structure change, use a watchpoint. You can set up to five watchpoints, including watchpoints for strings.
    A watchpoint can be either local or global. Local watchpoints are only valid in the specified program. Global watchpoints are valid in the specified program, and also in all the other programs it calls.
    Procedure
    To set a watchpoint, start the Debugger and proceed as follows:
    Choose Breakpoint ® Create watchpoint or the corresponding pushbutton. The Create Watchpoint dialog box appears:
    Decide whether you want to set a local or global watchpoint.
    Enter the program and the name of the field for which you want to set the watchpoint. In the Program field, the name of the program currently running is always defaulted.
    If you want your watchpoint to be activated each time the contents of the field change, the definition is now complete, and you can return to the Debugger by pressing ENTER .
    To create a conditional watchpoint, that is only activated when a particular situation arises, choose one of the following relational operators.
    Operator
    Meaning
    <
    Less than
    <=
    Less than or equal
    =
    Equal
    <>
    Not equal
    =
    Greater than or equal
    Greater than
    You can use the Comparison field option to specify whether the comparison is to be carried out with a value that you specify or with the contents of another field. Depending on your choice from step 6, enter a value or a field for the comparison.
    Result
    The system confirms the watchpoint and adds it to the list in the display. When you finish your debugging session, the watchpoint is automatically deleted unless you have explicitly saved it.
    Specifying Logical Links
    If you have more than one conditional watchpoint, you can specify a logical link between them:
    OR
    Only one of the specified conditions must be met
    AND
    All of the conditions must be met.
    Changing Watchpoints
    Choose Goto ® Control debugging ® Watchpoints or the Watchpoints pushbutton to display the watchpoint list. The following dialog box appears:
    Choose the pencil icon in the line containing the watchpoint you want to change.
    Change the watchpoint attributes in the Create/Change Watchpoint.
    Choose ENTER .
    Deleting Watchpoints
    You cannot delete watchpoints by choosing Breakpoint ® Delete or Breakpoint ® Deactivate/activate. Instead, proceed as follows:
    Choose Goto ® Control debugging ® Watchpoints or the Watchpoints pushbutton to display the watchpoint list.
    Choose the trashcan icon in the line containing the watchpoint you want to delete.
    Memory Monitoring with Watchpoints
    You can use watchpoints to display changes to the references of strings, data and object references, and internal tables. By placing an ampersand (&) in front of the object name, you can display the reference in question in hexadecimal format. With internal tables, you can also display the table header by placing an asterisk (*) at the beginning of the name.
    &objectname
    Displays the references of strings, internal tables as well as data and object references
    *itab
    Displays the table header of the internal table itab
    Example
    If a watchpoint is set for the object in question at runtime, the program is stopped as soon as the reference is changed. A short dump can be intercepted in this way to stop the program being terminated when the memory is overwritten.
    Analyzing Source Code
    The Debugger contains an extensive range of functions that help you to analyze the source code of a program. You can step through the source code of a program in four different ways. For further information, refer to Stepping Through the Source Code
    For information about functions within the source code display, see Displaying the Source Code
    There are also different display modes that provide various information and display the contents of individual fields, tables, and so on:

  • A Bunch of Droid X questions...still figuring out how to use it

    I got my Droid X about a week ago, I love it! But there are some things that I am still trying to figure out, who knows if they are even an option on the phone. Any help would be greatly appreciated.
    1) My calendar doesn't show both evens from my personal calendar that I synced with the google calendar and the holidays. It just shows the holidays coming up, not both that & my personal events.
    2) Does the camera zoom?
    3) Is there a way to set it to turn on and off at certain times every day or will I need an app for that?
    4) The photo gallery...I want my photos in certain folders. For example, I want my wedding photos under a wedding folder in the gallery, is that possible?
    5) I have downloaded  a few ringtones. But when I go to contacts to assign a person that ring tone, that ringtone is not on the list of tones to assign, just the preloaded tones. AND...how do I assign a downloaded tone to text messaging?
    6) Sometimes my browser won't zoom in my using my fingers (pinch/squeeze), but will if I double tap the screen. Is it a certain website that I am visiting that does this? I want the pinch/squeeze feature, not double tap.
    7) What is a good calendar/to-do-list/note pad free app all in one?

     I will try to answer as much as possible to help..
    1) My calendar doesn't show both evens from my personal calendar that I synced with the google calendar and the holidays. It just shows the holidays coming up, not both that & my personal events.
    I remember seeing a option in Google sync site that allowed you to hide you personal items, maybe I would search settings and make sure that this hasnt been set, I do not use Google for my appointment so I cant give you exact information of how to find it, but I know its on the site.
    2) Does the camera zoom?
    Yes, you can use the volume up and down to zoom in and out.
    3) Is there a way to set it to turn on and off at certain times every day or will I need an app for that?
    I do not believe you can have device power off and back on automatically but there is a number of apps that can disable notifications on a time schelduled but I do not have any names off the head.
    4) The photo gallery...I want my photos in certain folders. For example, I want my wedding photos under a wedding folder in the gallery, is that possible?
    I gallery just shows the list of avalible folders, if you copy the files into a folder they will be grouped to reflect this in the gallery.
    5) I have downloaded  a few ringtones. But when I go to contacts to assign a person that ring tone, that ringtone is not on the list of tones to assign, just the preloaded tones. AND...how do I assign a downloaded tone to text messaging?
    Place ringers in SD/Media/Audio/Ringers folder (If RINGERS folder isnt present, create it in the directory) under SD Card and the files will show in list.
    6) Sometimes my browser won't zoom in my using my fingers (pinch/squeeze), but will if I double tap the screen. Is it a certain website that I am visiting that does this? I want the pinch/squeeze feature, not double tap.
    Sounds like you may be use to using a capacitive screen but the Droid X uses a resistive touch screen and it requires a interaction directly with your finger unlike capacitive screens will respond to a point of a objects like a finger nail... Try making sure you are touching screen with your finger not your finger nail you may notice a better responce.
    7) What is a good calendar/to-do-list/note pad free app all in one?
    All my app are pay for these functions.. So I cant give many free apps but I am sure if you search Market you can find a few to select from.

    Hi,
    I am new to vc++ and indesign, i am using windows xp as OS and Indesign CS3 as version, now i want to know how to create an object for the ITextModel Interface (or) how to use the ITextModel interface, for getting the selected text and to manipulate the content, for this i tried myself to the best for more than a week,
    but i not get any solution or any idea to do it, so i post this scrap, if any one knows kindly help me immediately, if u want any more details kindly reply me i am ready to give..
    Regards,
    ram

    Hi, Ram,
    as Jongware already has explained in a previous thread, this is the scripting forum, the SDK forum is next door.
    Besides, your question has already been answered over there in SDK forum - with a reference to an existing example, including documented source. There is also plenty more documentation (780 pages alone in the programming guide) and other working examples.
    The brief response was a perfect match to the vague, general scope of the question. If you want more details, be more specific yourself. Do not just touch such major topics as selection, text, object architecture in one sentence to expect a silver bullet. Instead, stick to one detail, find and read the relevant examples and documentation (did I mention the programming guide?) yourself e.g. using keyword search. Quote your code where you're stuck.
    Being new to both VC++ and InDesign is an explanation but no excuse. IMO, same goes for "using windows xp as OS". All together are bad starting conditions if you intend to write a plugin. Even a seasoned C++ programmer with some years of experience in publishing quirks will easily require months, so don't become impatient after just a week.
    If you need quick results and have a programming background such as a recent Java101, reconsider scripting (this forum). It can bring you amazingly far and you'll learn InDesign through a simplified object model. Same principles apply - there is plenty documentation and a good choice of examples.

    Dirk

  • Can some one instruct on how to use SetRotate?

    I'm having to code in VB6 and need to know how to use the SetRotate command programmatically to set the view of the PDF to a different angle. I'm using AcroPDF.dll control in a form and would like the user to be able to change the angle of the PDF.
    According to the API reference, you use AcroPDPage.SetRotate but some how I need to tell it which page or control to apply it to and that what I don't understand.
    Can anyone help a new programmer make the correct calls to SetRotate in VB6?
    Thanks.

    Try getting a page object using PDDoc.AcquirePage first, then using the PDPage.SetRotate method, but note that this would not work with Reader. This method rotates a page, as opposed to the current view.
    I think the only way you can rotate the view with IAC is to use the JSO to execute the corresponding menu item, but I don't think you can get the current rotation, so this wouldn't be reliable and I'm not sure if it would work.
