How to use call back function ?

i have MlEditmanager class which extends xyzManager class. I also want to extend Eventdispatcher .. but it is not possible to extend more than one class ...
so the work around can be to create call back function. private var xyz:Function; --> how to use this syntax?
Can someone help me how to achieve this?
Urgent pls.

Though this is not your requirement, however in the source code callback functions are used. You can get clue from that.
Hope this helps

How to access Call Back Functions using *.dll in the Labview?

Hai,
I am Pavan Ram Kumar Somu.
I am new to Labview, currently I am working on MVB Interface.
I need to access the API functions from *.dll file in Labview, as of now , I am doing this with Call function Library node in Labview but it does not support the following data types like
    1. Pointer Arguments(To which memory it points in Labview)
    2. function pointers Arguments
    3 .pointers in structures and pointer structures in structures and many other data types.
Please Answer the below queries also:
1. How to pass pointer arguments to API functions in DLL and how to collect pointer
    return types from API functions in DLL
2. How to pass structure arguments to API functions in DLL and how to collect structure
    return types from API functions in DLL
3. How to use callback functions(nothing but function pointers) in Labview and how to
    collect callback fuctions return types from API functions in DLL
I need your help while passing these datatypes to API functions in DLL from labview.
Suggest me if there is any other alternative for implementing this task.
I am referencing some examples here:
Examples:
I)
Unsigned short int gf_open_device(void *p_device_config, unsigned long int client_life_sign_timeout, unsigned short int *device_error)
void *p_device_config: How to access/pass these arguments in LabView and to which memory location it points in LabView.
II) #include <windows.h>
     #include <process.h>
     HANDLE rcvEvent0, rcvEvent1;
/* Function call*/
CanGetReceiveEvent(handle[0], &rcvEvent0);
Above is a piece of C code, Now I want to use HANDLE datatype which is windows based, how to use these type in the LABVIEW.
With regards

Search the forum (forums.ni.com) for callback, pointer or handle, and you'll find that it is all possible, but not very easy.

How to use Call library function node for a function in dll with VOID data type

Hi All,
I would like to ask for your kind help,
I am facing an issue with the call library node.
I have a C++ function(stdcall), which has void as data type
error code XXXX(hwnd, lID, getValue, *void data1, *void data2)
the data1 and data2 types are always changing depending upoin the value of "getValue".
Primarily i can use call library node multiple times and adapt each node according to the data types of data1 and data2, and extract the values and use in the code. Here is no issue. Real question is:
My question:
How can i just use one time call library node and make a case depending upon the "getvalue", which will control the data type of data1 and data2. Here i really looking for solutions.
My trials:
i used varaints as input to the call libray node for data1 and data2, and selected Parameters in call libraby node as " Adapt to type". here labview just crashed.
i really appreciate your feedbackand suggestions.
Thanks

A variant is a very specific LabVIEW datatype (really a C++ type object internally) and trying to pass that to a function, which excepts a flat memory pointer there, for sure will crash very quickly.
As to endianess, yes Unflatten will be able to adjust for endianess, which in this case however is most likely exectly NOT what you want. So make sure that the you select native type for the endianess input on Unflatten from String. LabVIEW internally works with whatever is the native endianess, as will most likely your C++ DLL. The platform independent big endian format does only come into play when you receive data streams over some streaming interface like a network connection. Here it is desirable to use an endian format that is independent from the actual platform that generates and consumes the data stream. LabVIEWs default endianes is big endian here.
But as long as you pass data directly to native components like DLLs there is no difference in endianess between what LabVIEW uses and what those components use.

How to use call back and user session id based conversation with web service in weblogic 6.1 sp2 ?????????

Hi, every one:
Here's my question of my day - >>>
I am using weblogic 6.1 SP2 right now - running on Unix and Win 2K, and
I got a web service up and running called Price Update web service through
which user can pick up a price and push a deal to another web service
called: deal service, the deal service will take the user deal and book the
deal ( sending a JMS message to a Queue, a MD will pick up and do the work,
then send the confirmation to another JMS Queue ), then the confirmation
will be picked up and sent to another web service , called: User Deal
Confirmation Service, here's the question:
1. Since the client application is only allowed to see its own confirmed
deals, how I can make the confirmed deal encrypted based on a server
generated key or the session id that client application provides
2. Now, I have 3 webservices: update, deal and confirm, each of them has a
client.jar file available - from the client application point of view, do I
need all these 3 client.jar, or I just need one of them ?????
3. How can I use web service call back in wls 6.1 sp2 ?????? - in the 7.0
beta, you can do this easily in the workshop, in the second question above,
I think I need some how relate the confirmation to the client conversation
id ??
thanks a lot for the input, have a nice day.

How to unrigister the call back function,in vb6 with DAQmx 8.5

I use daqmx api which named DAQmxRegisterEveryNSamplesEvent to register my call back function,When I invoke the function DAQmxErrChk (DAQmxStopTask(taskHandleAnalog)) to stop my Task.then i call the procedure AD_OPEN  again,it raise an error ,tell me that i need to unregister the event,the data has transfer into the buffer.how can i unregister the event,please look at the following code.
Spoiler (Highlight to read)
Private Sub create()
   Dim channel As String
    Dim minVoltage, maxVoltage As Double
    Dim samplesPerChannelPerRead As Double
    Dim sampleMode As Long
    Dim boolVal As Boolean
    On Error GoTo AdErrorHandler:
    ' Get values from UI controls
    channel = "Dev2/ai1:2"
    minVoltage = -10
    maxVoltage = 10
    samplesPerChannelPerRead = 100
     If (taskHandleAnalog <> 0) Then
         DAQmxErrChk (DAQmxStopTask(taskHandleAnalog))
        DAQmxErrChk (DAQmxClearTask(taskHandleAnalog))
        taskhandle = 0
    End If
    ' Configure the task
    DAQmxErrChk (DAQmxCreateTask("", taskHandleAnalog))
     DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandleAnalog, "Dev2/ai0", "", DAQmx_Val_InputTermCfg_RSE, minVoltage, maxVoltage, DAQmx_Val_VoltageUnits2_Volts, vbNullString))
    DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandleAnalog, channel, "", DAQmx_Val_InputTermCfg_Diff, minVoltage, maxVoltage, DAQmx_Val_VoltageUnits2_Volts, vbNullString))
End Sub
Private Sub AD_Open()
    DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandleAnalog, "", 200, DAQmx_Val_Rising, DAQmx_Val_AcquisitionType_ContSamps, samplesPerChannelPerRead))
    'Find number of samples specified
    DAQmxErrChk (DAQmxGetTaskNumChans(taskHandleAnalog, numChannels))
    'Configure Event Callbacks
    DAQmxErrChk (DAQmxRegisterEveryNSamplesEvent(taskHandleAnalog, 1, 4, 0, AddressOf EveryNSamplesEventHandler1, Nothing))
ReDim dataBuffer(numChannels * samplesPerChannelPerRead - 1)
    ' Start the DAQmx Task
'    DAQmxErrChk (DAQmxCfgDigEdgeStartTrig(taskHandleAnalog, "/Dev1/PFI2", DAQmx_Val_Edge1_Falling))
    DAQmxErrChk (DAQmxStartTask(taskHandleAnalog))
    ' Update UI
    Exit Sub
AdErrorHandler:
    MsgBox Err.Description
End Sub

This may be a bit late, so hopefully you found this on your own. But in order to unregister the event pass a null value for the callback function parameter in the DAQmxRegisterEveryNSamplesEvent function (Nothing in VB).

Here is the procedure
1. Create a new smartforms
Transaction code SMARTFORMS
Create new smartforms call ZSMART
2. Define looping process for internal table
Pages and windows
First Page -> Header Window (Cursor at First Page then click Edit -> Node -> Create)
Here, you can specify your title and page numbering
&SFSY-PAGE& (Page 1) of &SFSY-FORMPAGES(Z4.0)& (Total Page)
Main windows -> TABLE -> DATA
In the Loop section, tick Internal table and fill in
ITAB1 (table in ABAP SMARTFORM calling function) INTO ITAB2
3. Define table in smartforms
Global settings :
Form interface
Variable name Type assignment Reference type
ITAB1 TYPE Table Structure
Global definitions
Variable name Type assignment Reference type
ITAB2 TYPE Table Structure
4. To display the data in the form
Make used of the Table Painter and declare the Line Type in Tabstrips Table
e.g. HD_GEN for printing header details,
IT_GEN for printing data details.
You have to specify the Line Type in your Text elements in the Tabstrips Output options.
Tick the New Line and specify the Line Type for outputting the data.
Declare your output fields in Text elements
Tabstrips - Output Options
For different fonts use this Style : IDWTCERTSTYLE
For Quantity or Amout you can used this variable &GS_ITAB-AMOUNT(12.2)&
5. Calling SMARTFORMS from your ABAP program

Smartform
you can check this link here you can see the steps and you can do it the same by looking at it..
http://smoschid.tripod.com/How_to_do_things_in_SAP/How_To_Build_SMARTFORMS/How_To_Build_SMARTFORMS.html
SMARTFORMS STEPS.
1. In Tcode se11 Create a structure(struct) same like the Internal table that you are going to use in your report.
2. Create Table type(t_struct) of stracture in se11.
3. In your program declare Internal table(Itab) type table of structure(struct).
4. Define work area(wa) like line of internal table.
5. Open Tcode Smartforms
6. In form Global setting , forminterface Import parameter define Internal table(Itab) like table type of stracture(t_struct).
7. In form Global setting , Global definitions , in Global data define Work area(wa) like type stracture(struct).
8. In form pages and window, create Page node by default Page1 is available.
9. In page node you can create numbers of secondary window. But in form there is only one Main window.
10. By right click on page you can create windows or Go to Edit, Node, Create.
11. After creating the window right click on window create table for displaying the data that you are passing through internal table.
12. In the table Data parameter, loop internal internal table (Itab) into work area(wa).
13. In table there are three areas Header, Main Area, Footer.
14. Right click on the Main area create table line by default line type1 is there select it.
15. Divide line into cells according to your need then for each cell create Text node.
16. In text node general attribute. Write down fields of your work area(wa) or write any thing you want to display.
17. Save form and activate it.
18. Then go to Environment, function module name, there you get the name of function module copy it.
19. In your program call the function module that you have copied from your form.
20. In your program in exporting parameter of function pass the internal table(itab).
SAP Smart Forms is introduced in SAP Basis Release 4.6C as the tool for creating and maintaining forms.
SAP Smart Forms allow you to execute simple modifications to the form and in the form logic by using simple graphical tools; in 90% of all cases, this won't include any programming effort. Thus, a power user without any programming knowledge can
configure forms with data from an SAP System for the relevant business processes.
To print a form, you need a program for data retrieval and a Smart Form that contains the entire from logic. As data retrieval and form logic are separated, you must only adapt the Smart Form if changes to the form logic are necessary. The application program passes the data via a function module interface to the Smart Form. When activating the Smart Form, the system automatically generates a function module. At runtime, the system processes this function module.
You can insert static and dynamic tables. This includes line feeds in individual table cells, triggering events for table headings and subtotals, and sorting data before output.
You can check individual nodes as well as the entire form and find any existing errors in the tree structure. The data flow analysis checks whether all fields (variables) have a defined value at the moment they are displayed.
SAP Smart Forms allow you to include graphics, which you can display either as part of the form or as background graphics. You use background graphics to copy the layout of an existing (scanned) form or to lend forms a company-specific look. During printout, you can suppress the background graphic, if desired.
SAP Smart Forms also support postage optimizing.
Also read SAP Note No. 168368 - Smart Forms: New form tool in Release 4.6C
What Transaction to start SAP Smart Forms?
Execute transaction SMARTFORMS to start SAP Smart Forms.
Key Benefits of SAP Smart Forms:
SAP Smart Forms allows you to reduce considerably the implementation costs of mySAP.com solutions since forms can be adjusted in minimum time.
You design a form using the graphical Form Painter and the graphical Table Painter. The form logic is represented by a hierarchy structure (tree structure) that consists of individual nodes, such as nodes for global settings, nodes for texts, nodes for output tables, or nodes for graphics.
To make changes, use Drag & Drop, Copy & Paste, and select different attributes.
These actions do not include writing of coding lines or using a Script language.
Using your form description maintained in the Form Builder, Smart Forms generates a function module that encapsulates layout, content and form logic. So you do not need a group of function modules to print a form, but only one.
For Web publishing, the system provides a generated XML output of the processed form.
Smart Forms provides a data stream called XML for Smart Forms (XSF) to allow the use of 3rd party printing tools. XSF passes form content from R/3 to an external product without passing any layout information about the Smart Form.
SmartForms System Fields
Within a form you can use the field string SFSY with its system fields. During form processing the system replaces these fields with the corresponding values. The field values come from the SAP System or are results of the processing.
System fields of Smart Forms
&SFSY-DATE&
Displays the date. You determine the display format in the user master record.
&SFSY-TIME&
Displays the time of day in the form HH:MM:SS.
&SFSY-PAGE&
Inserts the number of the current print page into the text. You determine the format of the page number (for example, Arabic, numeric) in the page node.
&SFSY-FORMPAGES&
Displays the total number of pages for the currently processed form. This allows you to include texts such as'Page x of y' into your output.
&SFSY-JOBPAGES&
Contains the total page number of all forms in the currently processed print request.
&SFSY-WINDOWNAME&
Contains the name of the current window (string in the Window field)
&SFSY-PAGENAME&
Contains the name of the current page (string in the Page field)
&SFSY-PAGEBREAK&
Is set to 'X' after a page break (either automatic [Page 7] or command-controlled [Page 46])
&SFSY-MAINEND&
Is set as soon as processing of the main window on the current page ends
&SFSY-EXCEPTION&
Contains the name of the raised exception. You must trigger your own exceptions, which you defined in the form interface, using the user_exception macro (syntax: user_exception <exception name >).
Example Forms Available in Standard SAP R/3
SF_EXAMPLE_01
Simple example; invoice with table output of flight booking for one customer
SF_EXAMPLE_02
Similar to SF_EXAMPLE_01 but with subtotals
SF_EXAMPLE_03
Similar to SF_EXAMPLE_02, whereby several customers are selected in the application program; the form is called for each customer and all form outputs are included in an output request
Advantages of SAP Smart Forms
SAP Smart Forms have the following advantages:
1. The adaption of forms is supported to a large extent by graphic tools for layout and logic, so that no programming knowledge is necessary (at least 90% of all adjustments). Therefore, power user forms can also make configurations for your business processes with data from an SAP system. Consultants are only required in special cases.
2. Displaying table structures (dynamic framing of texts)
3. Output of background graphics, for form design in particular the use of templates which were scanned.
4. Colored output of texts
5. User-friendly and integrated Form Painter for the graphical design of forms
6. Graphical Table Painter for drawing tables
7. Reusing Font and paragraph formats in forms (Smart Styles)
8. Data interface in XML format (XML for Smart Forms, in short XSF)
9. Form translation is supported by standard translation tools
10. Flexible reuse of text modules
11. HTML output of forms (Basis release 6.10)
12. Interactive Web forms with input fields, pushbuttons, radio buttons, etc. (Basis-Release 6.10)

How do you call a function within a package using OCI in C

I am trying to call a user-defined function in Oracle 8.1.7 using OCI in C. I am getting a ORA-06550 PLS-00221, <function name> is not a procedure or is undefined. Can anyone tell me how I would call a function using OCI?
Thanks.

I think I figured it out, but I am now getting a ORA-06512 error; numeric or value error: character string buffer too small.

Call a special function in the dll using Call Library Function Node????

Dear all,
I am calling a special function in the dll using call library function node. There is a input parameter that it is a enum type in this function. I don't know how to deal this parameter for calling this function.Has anybody solved this problem?Please advise!
I am appreciated of you anytime.

Most of the times an enum is just a U8/U16/U32, internally so probably you can call it with just a U8/U16/U32 or something. For the correct value you have to look at the definition.

How to use a back button in action pages?

Hi all,
I have created a user login page,home page and user profile page.
If the user provide correct username and password in the login page he will be taken to home page.
In the home page he will be having his username and a link to view his profile.
When the user click on the link "My Profile(user profile)" he wil be taken to that page.
In my profile page the user can edit only his firstname,lastname and password .
On the user profile page i have placed a Back Button(using javascript: on onclick event i have used history.back()) to go back to home page after editing his profile.
If the user edit his profile for n-number of times then atlast if he wants to go back to home page-then he wil cilck the back button.
Now the problem occurs like the back button not going to home page and it simply going back with the edited history.
How to use a back button in action pages; without repeating the actions done on the page; how to redirect to the users home page?
I simply used the hyperlink in userprofile page to go to home page but when i click onit it is displaying blank home page.
I'm using hibernate orm mapping; cflogin and cflogout tags.
Any help appreciated,

I can see your problem. You may use javascript:history.go(-1), javascript:history.go(-2), ..., to go back one page, two pages, and so on. But how does one go back an arbitrary n pages? The link href="home.cfm" isn't a good solution for the browser. It makes a new call to the server which, as you may have discovered, can overwrite all the changes made at the browser.
You should use the Javascript variable history.length. If you open n links in succession, starting from page0.cfm, then the browser holds the value of history.length as n. So, experiment with something like
<a href="javascript:history.go(-history.length)">Go home</a>
or
<a href="javascript:history.go(-history.length+1)">Go home</a>

How to use Round off function in TAX Formula

Dear All,
         I have to do Round off in the Tax Formula. Hence I was suggested by the SAP Forum Team to use Round off function in the Tax Formulae.
         But sir I don't know how to use Round off function in the Tax Formulae.
        For Eg. BaseAmt = Total
                    TaxAmt = BaseAmt * Rate
           Now within this Eg. How will i use the Round off function and where i will use it.
           Please guide me with example.
Regards
Hitesh Parsawala

Hi Hitesh,
you can do like this
Cess_ST_TaxAmt=Round(Cess_ST_BaseAmt*Cess_ST_Rate,0)
where you can introduce rounding function by choosing from dropdown available in Operation and by click on Insert.
It will post following in formulla window
Round (Number, Decimals as Number)
where in parameter you have to give 1.Number-which is to be round and 2.Decimals as Number-as per your requirement like by 2 decimal or 0 decimal
If required give me call,

How do I call a function in java?

I'm calling a function called lightParse() from the method. But, I'm getting an error:
F:\Data>javac -classpath xerces.jar;xalan.jar;classpath%; Test.java
Test.java:22: lightParse(java.lang.String) in Test cannot be applied to ()
lightParse();
^
The scenario or code portion is :

import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;

public class Test extends JFrame
     JList list;
     JScrollPane listContainer;
     public Test()
          setSize(300, 300);
          setVisible(true);
          initialize();
          lightParse(); // calling the function
     public void initialize()
          list = new JList(new DefaultListModel()); // Set the initial model
          listContainer = new JScrollPane(list);
          listContainer.setSize(new Dimension(200, 200));
          getContentPane().setLayout(new BorderLayout());
          getContentPane().add(listContainer, "Center");
          validate(); // Validate the screen
// The function is the following
     public void lightParse(String url)
          DocumentBuilder parser;
          DocumentBuilderFactory factory =
                    DocumentBuilderFactory.newInstance();

                    parser = factory.newDocumentBuilder();
                    Document doc = parser.parse(url);
How do I call the function correctly with the right parameter?
Thanks in advance for the answer.

u r calling lightParse method without passing the expected "String" argument. There must not be an overloaded method for lightParse without any arguments.
So u should use this:
lightParse(some string here);
Hope this explains.

How to use 'several screen function' used to be in os x 10.6

hi ! ^^
how r u ? good !
how to use 'several screen function' used to be in os x 10.6 ??
it was possible to change whole screen with 'command + arrow keys' (option + arrow keys maybe ??)
but, in os x 10.7, it seems it is not possible. and instread of it 'mission controls' that is not uesful ..
no windows drive direct access. no several screen function. crash when control panel ask me administration right.
os x 10.5 or 10.4 was much easy to control.
plz fix and add good functions of 10.6 , remove good functions is not called 'upgrade'.

You can still do it with CONTROL + Arrow keys, the same as 10.6

How do you call a function in an attached MovieClip from the current MovieClip?

Hi there,
I have this MovieClip A (converted as a symbol) and put in my
main MovieClip B using attachMovie() , and I am wondering how I can
call a function defined in A from within B.
Is it possible?
Thanks

Hi kglad,
yes, I did the attachMovie of the symbol B and it seems like
none of the ActionScript written in B was not carried over.
This is how I built B into a symbol :
(1) Two layers ( one for the ActionScript only, the other for
the Components)
(2) I defined the functions to be called remotely by A in the
ActionScript layer
(3) I selected all the components in the Components Layer and
did a Convert To Symbol
(4) I added the Symbol into A's Library
(5) I used attachMovie to instantiate the Symbol of B
I must have missed out something somewhere
Thanks

I think you can use a javascript method to go back to the previous browser page.
