Calling Sub from Main

I am attaching a full folder that contaions a small project with three VI s. What I want to do is this : Run the MAIN.vi. Choose the required sub.vi to load and click Auto Load. The Main FP is closed and the Sub VI loads.
All working fine in design mode. But not working when EXE is built. ( No hardcoded path refernces are used )
Unable to find out why - for sure there seems to be a problem with the file paths . And I am taking care to strip one more level when in RunTime mode. Still it does not work. Not sure why - any ideas welcome.

The additional strip is needed if you access files _outside_ of the .exe. For example a .ini in the install folder.
If you check a VI path it includes the .exe as a "virtual folder", thus you'll need an extra strip.
But do be very careful with that. Starting in LabVIEW 2009, the executables were a zip-like format, meaning that the folder heirarchy is maintained. In LabVIEW 8.X, the executable was a flat format. So the double strip was needed to get the folder of the executable. In modern systems, you should be using the Application Directory primitive instead of the VI Path when looking for files outside of the executable (like ini files). When in the development environment, the Application Directory gives the folder in which the project file is. So that primitive is useful in both developement and run time environments.

Calling servlets from main()?

Hi
I would like to know that while calling servlets from another class having main(), how can we set the type of request i.e. put, post or get?
Thanks

use the method - setRequestMethod( "POST") of HttpURLConnection for setting the method to POST.Similarly for other methods..

Custom component calling function from main.mxml

I have a main.mxml that has the following function in it:
public function SubChooseField(evt:Event):void{
Alert.show( "Sub has been chosen" );
main.mxml also places the following custom component:
<?xml version="1.0" encoding="utf-8"?>
<mx:ComboBox xmlns:mx="
http://www.adobe.com/2006/mxml"
width="180" close="parent.SubChooseField(event)">
<mx:dataProvider>
<mx:Object data="1" label="choice 1 />
<mx:Object data="2" label="choice 2" />
<mx:Object data="3" label="choice 3" />
</mx:dataProvider>
</mx:ComboBox>
I want it so that when you chose one of the options in the
comboBox, it will call the function SubChooseField in the
main.mxml. But when I compile this, no matter what i try, i get the
error:
Error: Call to a possibly undefined method SubChooseField
through a reference with static type my_custom_opponent.
OR if i change the codeand remove the 'parent' to say:
close="SubChooseField(event)"> i get error:
Error: Call to a possibly undefined method SubChooseField.
any help much appreciated.

Rather than trying to use parent, using events might help
here. In your main mxml file, just listen for the change event that
is dispatched from your custom component. Since it is a ComboBox
component, it automatically dispatches this event. If your
component was more complex, you would need to dispatch a custom
event.
If your custom component was named CustomCombo, then the mxml
in your main file would look something like this:
<ns1:CustomCombo id="cb" x="70" y="39" width="160"
change="SubChooseField(event)"/>

Call subscreen from main screen

Dear all,
I have a subscreen and from that subscreen i am calling another normal screen using 'call screen' statement. After doing some manipulation in the normal screen i want to go back to the subscreen on clicking 'BACK' button. i tried 'leave to screen' and 'call screen' in PAI of normal screen but it is not working. how to come back to the subscreen again?
Thanks in advance,
Aswin.

Dear Friend,
You include a subscreen screen using the CALL SUBSCREEN statement in the flow logic of the main screen.
To include a subscreen screen in the subscreen area of the main screen and call its PBO flow logic, use the following statement in the PBO event of the main screen:
This statement assigns the subscreen screen with number <dynp> to the subscreen area called <area>. With <prog> you must specify the ABAP program in which the subscreen screen is defined. If it does not find a corresponding subscreen screen, a runtime error occurs. The PBO flow logic of the subscreen screen is also included at the same point. This can call PBO modules of the ABAP program in which the subscreen screen is defined. At the end of the subscreen PBO, the global fields from the program are passed to any identically-named screen fields in the subscreen screen. The PBO flow logic of the subscreen screen can itself include further subscreens.
The name <area> of the subscreen area must be entered directly without inverted commas. You can specify the names <prog> and <dynp> either as literals or variables. If you use variables, you must declare and fill identically-named variables in the ABAP program. The screen number <dynp> must be 4 characters long. If you do not assign a subscreen screen to an area, it remains empty.
PROCESS BEFORE OUTPUT.
CALL SUBSCREEN <area> INCLUDING <prog> <dynp>.
find the Below Example Code.
DATA: ok_code TYPE sy-ucomm,
      save_ok TYPE sy-ucomm.
DATA: number1(4) TYPE n VALUE '0110',
      number2(4) TYPE n VALUE '0130',
      field(10) TYPE c, field1(10) TYPE c, field2(10) TYPE c.
CALL SCREEN 100.

SET PF-STATUS 'SCREEN_100'.
ENDMODULE.
MODULE fill_0110 OUTPUT.
field = 'Eingabe 1'(001).
ENDMODULE.
MODULE fill_0120 OUTPUT.
field = field1.
ENDMODULE.
MODULE fill_0130 OUTPUT.

ENDMODULE.
MODULE fill_0140 OUTPUT.

ENDMODULE.

IF save_ok = 'OK1'.
    number1 = '0120'.
    field1 = field.
    CLEAR field.
ENDIF.
ENDMODULE.
MODULE user_command_0130 INPUT.
IF save_ok = 'OK2'.
    number2 = '0140'.
    field2 = field.
    CLEAR field.

    WHEN 'SUB1'.
      number1 = '0110'.
    WHEN 'SUB2'.
      number1 = '0120'.
      CLEAR field1.
    WHEN 'SUB3'.
      number2 = '0130'.
    WHEN 'SUB4'.
      number2 = '0140'.
      CLEAR field2.
ENDCASE.
ENDMODULE.
The screen flow logic for screen 100 is as follows:
PROCESS BEFORE OUTPUT.
MODULE status_100.
CALL SUBSCREEN: area1 INCLUDING sy-repid number1,
                  area2 INCLUDING sy-repid number2.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
MODULE save_ok.
CALL SUBSCREEN: area1,
                  area2.
MODULE user_command_100.
The screen flow logic of subscreen screens 110 and 130 is:
PROCESS BEFORE OUTPUT.
MODULE fill_0110|0130.
PROCESS AFTER INPUT.
MODULE user_command_0110|0130.
The screen flow logic of subscreen screens 120 and 140 is:
PROCESS BEFORE OUTPUT.
MODULE fill_0120|0150.
PROCESS AFTER INPUT.
When you run the program, a screen appears on which subscreens 110 and 130 are displayed. The pushbuttons on the main screen allow you to choose between two subscreen screens for each screen area. The pushbuttons on the subscreens allow you to transfer the data from subscreens 110 and 130 to subscreens 120 and 140.
Since the same field name FIELD is used on all subscreens, the identically-named ABAP field is transferred more than once in each PBO and PAI event of the main screen. For this reason, the values have to be stored in the auxiliary fields FIELD1 and FIELD2 in the ABAP program.
The pushbuttons on the subscreen screens have different function codes, and they are handled normally in an ABAP field. If the function codes had had the same names, it would again have been necessary to use auxiliary fields.

Call vi from main vi

Hi
I build a vi in labview and I called it 1.vi , then I open new vi and called it 2.vi , then I build main vi , this main contain two bottom one called " called 1.vi " the another called " called 2.vi "
What I want if I press on bottom " called 1.vi " this bring 1.vi file and appear on screen in main VI ,, who can I do that
If some one have example I would be very thankful to him

Hey wisam,
As attachmend you will find a little example, there may (will) be better solutions, it's only a suggestion resulted from clickling a little bit within LabVIEW. It's in 8.2

How to add button inside move clip and call it from main timeline?

Hi,
On the main timeline I have a movie clip called clock_mc and playBtn
playBtn is placed in the center of clock_mc
When you press playBtn clock_mc starts playing
playBtn.addEventListener(MouseEvent.CLICK, playClock);
function playClock(event:MouseEvent):void
    if (event.target == playBtn)
        clock_mc.play();
        playBtn.visible = false;
        trace ("play button was clicked");
This is working fine for me.
But I want to add replayBtn to the last frame of clock_mc and set up the function on main Timeline.
Another words when the clock_mc rich last frame you see replayBtn.
code example:
replayBtn.addEventListener(MouseEvent.CLICK, playClock);
    if (event.target == replayBtn)
        clock_mc.play();
        replayBtn.visible = false;
        trace ("replay button was clicked");
I've tryed to placed the replayBtn on the stage on the main timeline and I've set it up to replayBtn.visible = false;
And then I add replayBtn.visible = true; to last AS frame of clock_mc but it wont work
Even when I put the button physically to the last frame of clock_mc it will not work either.
Please help

I've solved the problem:-)
I've set replayBtn.visible = false; on first frame of clock_mc
and replayBtn.visible = true; at the last frame
and than as you sugested I'v add:
clock_mc.replayBtn.addEventListener(MouseEvent.CLICK, replayClock);
function replayClock(event:MouseEvent):void
        clock_mc.play();
        trace ("replay button was clicked");
I couldn't see replayBtn at the firs stage because I have clockTween assosiated with clock:
clockTween = new Tween(clock_mc, "x", Regular.easeOut, -469,438, .5, true);
and I had replyBtn in the wrong place so when clock_mc was coming up on the stage replayBtn was on the left side of the stage :/
Now I have to solve only one thing.
Maybe you would have any suggestions please.
I've set up stop(); in a first frame of clock_mc
that when you see clock_mc sliding in it has to wait for playBtn to be clicked
because I have two tween:
        clockTween = new Tween(clock_mc, "x", Regular.easeOut, -469,438, .5, true);
        playTween = new Tween(playBtn, "x", Regular.easeOut, -720,514, .5, true);
        playBtn.visible = true;
so when you click on playBtn:
function playClock(event:MouseEvent):void
    if (event.target == playBtn)
        clock_mc.play();
        playBtn.visible = false;
        trace ("play button was clicked");
everythink is working fine except when I clik on replayBtn it play for I sec because there is stop(); on the first frame of clock_mc

Simply way to make sub vi and call it form main vi

I'm a beginner and have major problems to make a sub vi and call it from main vi. I'm going to do a save dialog where is extra info for my saving and want to call dialog from main vi and after that save info to a file or database. I want that save dialog appears after i press button. I attach sub vi where is no functionality yet.
Attachments:
save_dialogsub.vi ‏21 KB

The first step is to connect the controls and indicators that you want to pass information to and from your main vi.
You right-click on the icon at the top right corner of the Front Panel and select "Show Connector". Typically put inputs at the left and outputs at the right side of the connector pane. Save it.
Open the main vi. Go to the block diagram. Click on "Select a vi" inside the Functions Palette. And choose the sub vi you prepared. Then wire it up inside your main vi.

Problem in Calling Sub VI remotely from a main VI in a Web Browser.

Hi i am Calling Sub VI remotely from a main VI in a Web Browser.
My task details:
I my project i am fechting data from a MySQL data base and storing in a table on the main VI front panel.For User help i am calling a sub VI front panel which is consisting of a progress bar and percentage indicator.It indicates the user that the data is loading from the DB.The main purpus of a subVI is to make the GUI more user friendly..by displaying the SubVI front panel until whole data is loaded into the table and closing Immediately after load complete.
What i did?
To call a SUB VI i just right clicked on the subVI icon on the main VI >> SubVI node setup>> Show front panel when called.
In main VI Execution property i have seected Preallocated clone reentrant execution
In Sub VI Execution property i have seected Non- reentrant execution.
If i select Preallocated clone reentrant execution in Sub VI while calling sub VI i am getting warning message saying subVI front panel cannot be controlled remotely.
Promblem I am facing:
It is working perfect in a server machine(as a stand alone) but when i call the same VI or application in remote system i abserved two issues
1. When i call a sub VI every time the front panel is coming in both server and client machine.I want the subVI panel to display only in the client machine, other wise the user sitting in front of the server will be confused by seeing many popups(SubVIs) in his system.
2. When one client is calling a SubVI, the other user should wait until the the sub vi displayed and closed in the 1st client.Means the simultaniously more than one client cant access the SubVI.In this case i can access the main VI simultaniously but not the SubVI.
Please give me the solution.It wil be very helpful for me.Thank You in advance.
Thanks & Regards

I did some prijects with Siebel, but we used JMS for sending and retrieving message between Siebel and BPEL. Can you use this solution? This also gives you the advantage that you can guarantee that the transactionis committed and placed in a queue. You can also bring down the BPEL environment without interfering the Siebel environment, because the communication is done via JMS (queueus)

Sub VI to enter database data taking more time when calling from main VI

Hi All,
I created a sub vi to enter data to a new database, after reading from another database. when i executed that sub vi alone, it took only 2 minutes to enter 20000 records. But when i called that sub VI from my main VI, its taking 35 minutes to enter 20000 records.
my maiin vi has another while loop running parallelly which will perform some other operations. How to handle memory in this case? i mean when i call my sub vi from main vi, i need to give complete processor memory for that sub vi. is it possible?
please help. thanks in advance.
Sooraj

Hi Oliver,
in your example the numeric data is passed from sub-vi to main only when sub-vi terminates, this is what it's supposed to be when you fetch the data from the connector output of a sub-vi.
You can use queues function to exchange data between sub-vi and main.vi; take a look at the example Message Logging with Named Queue.vi.
An alternative method is passing to sub-vi a reference of an indicator (or control) and update its value on the fly.
See example.

Show truly dangerous to call from main?

In this JDC tutorial
http://java.sun.com/developer/JDCTechTips/2003/tt1208.html#1
the author claims that it is dangerous to call a Frame's show method from the thread executing your program's main, which is probably how 99% of us do it. Instead he claims that to be truly multithread safe, you need to call show from the AWT event thread using the invokeLater mechanism.
Is this really true? Does anyone know of a good discussion of this elsewhere? And if so, then how come Sun does not document it, say, in the show method? It is a disgrace to not mention such a critical fact right in the method itself if it is truly necessary.
I presume that if the author's point is true, then it holds for any Window or subclass (e.g. Dialog as well as Frame)?
Finally: if you truly do need to call show on the AWT event thread, then what about calling pack? (Contrary to what his article seems to say, calling show does NOT seem to automaticly call pack, at least for Frames.) Should you also only call pack from the event thread too? And are there any other methods that should only be called from the event thread?

I would question the true risk here. What the author of the article is describing is creating more frames or dialogs from the main thread. However the creation of the initial frame is pretty safe to call show on from your primary thread.
In general it is always a good practice to do all GUI related work in the event thread. Updating fields/labels, etc. should be done in the event thread and therefore calling show on a sub frame or dialog should also be done in the event thread.

How to trace/debug main workflow calling sub workflow.

Guys,
I am calling Sub workflow from MAIN workflow.
I am able to trace till beginning of sub workflow, with the help of workflow log.
But, is it possible to trace/debug the sub workflow as well(in single stretch).
Please guide with t-codes & procedures(links).......
Regrads.
santosh.

Hi Santosh,
You should be able to see the technical log for the subflow as well - but perhaps that's not what you are asking.
First, you should always be able to 'trace' your subflows by starting them directly via SWUS. Then you will have the log to review.
You can also set the workflow trace on via SWU9.
Hope this helps,
Sue

DLL Wrapper works when functions called out of main(), not from elsewhere?

Hello all,
I am currently trying the JSAsio wrapper out ( http://sourceforge.net/projects/jsasio )
Support on this project is nearly unexisting and a lot of people seem to complain that it doesn't work well.
It works very nicely here, I wrote a few test classes which called some functions (like playing a sound or recording it) and had no problems whatsoever.
These test classes were all static functions and ran straight out of the main() method and printed some results to the console.
     public static void main(String[] args)
          boolean result = callFunction();
          .. end..
     public static boolean callFunction()
          initASIO();
          openASIOLine();
          return true;
     }The results were all great!
Then I tried to implement these test classes into my swing-based applications. So I want to call these same functions, as in the test classes, as a result of any user action (for example, selecting the asio driver in a combobox) But then these asio driver functions just stop to work. I get errors saying that the ASIO driver is not available. (meaning that the dll wrapper loads the wrong asio driver or can't load one at all)
The library path and classpath are all set correctly, exactly the same as the test classes. Even copied the test code word for word in to my swing applications but it still will not work. I am calling these functions in a new Thread, and even put them in a static methods to try and get that working. When calling these asio methods from the main() method AFTER I set up my components gives me the desired results as well. But as soon as I call these same methods (which are in the same class) from a swing event, it fails;
public class ASIOTest
     public static void main(String[] args)
          ASIOTest test = new ASIOTest();
          test.callFunction(); // <-- WORKS
     public ASIOTest()
          initializeComponents();
     private void initializeComponents()
          frame = new JFrame();
          choices = new JComboBox();
          choices.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent event)
                 // user made selection
                new Thread(
                        new Runnable() {
                            public void run() {
                                try
                                     callFunction(); // <-- DOES NOT WORK
                                catch (Exception e)
                                    e.printStackTrace();
                        }).start();
     public void callFunction()
          initASIO();
          openASIOLine();
}Is there something fundamental I am missing here?
For what reasons can an application which uses JNI functions go wrong when working in a swing enviroment? (and out of a static context, although this does not seem to make any difference, eg. when calling these functions from static methods inside another class, inside a new thread when the user has generated an event)
I am hoping someone could point me in the right direction :-)
Thank you in advance,
Steven

The environment is different so one works and the other doesn't.Thank you for your fast reply!
Well, I am running the "updated" version from the same environment; I copied the jframe, and a jcombobox into my original test class which only ran in the java console. Consider my second code example in my original post as the "updated" version of the first code example. And as I pointed out, it works fine when I call the jni functions in the main method, but not when I call it from inside the ActionListener.
Or am I again missing something essential by what you mean with a different environment? The classpath and the working directory is exactly the same, as is the Djava.library.path option. :-)
Thanks again!

Can I disable "Slide to Call" from main screen? Forced to take call on accidental swipe

I have an iPhone 4s with iOS7 and I seriously do not like the "Slide to Call" feature from the main screen and would like to disable it. I would still like to see notifications on the home screen. I have accidentally swiped a call amongst other notifications and NO FUNCTION BUTTONS POP UP TO LET ME CANCEL THE CALL!. Seriously. A blank screen. I make an accidental swipe and now have to talk to someone I didn't want to talk to at the time.
Let me better describe the situation.
The 4s phone was locked. I had received a call and a text which were displayed on the home screen. I attempted to swipe the text, but hit the call. NO BUTTON, I had a blank screen and the call was going off in the 4s ear piece. I had to take the call or look totally stupid. I was just so angry that there was no way for me to end the call. In the second after the connection was made, after having held it to my ear and moved it away a few times, the buttons (End, speaker, etc) finally appeared.

You can always press the Sleep/Wake button.
If you have the iPhone ear-phones on, you can press the the remote button also.

Material exchane ,copy pricing and conditions from main item to sub item.

Hi All,
We are using parts exchange/interchangeability in the transaction ME22N,
While using ME22N we are exchanging main item with interchangeable part and while doing so we want to copy pricing and conditions from main item to sub item.
But its not happening.
As per sap help its possible, details describe below.
http://help.sap.com/erp2005_ehp_04/helpdata/en/c2/0a5288b77d11d3bcce00105ab03aee/content.htm
Price Determination by Copying from Main Item
In the case of price determination by copying from the main item, the net price of the originally ordered part is still used for the superseding part in a part exchange.
The system copies all conditions from the main item to all sub-items and takes into account the order quantity for the main item when calculating scale prices. It does not take into account the conditions and scale prices that exist for the interchangeable part.
You cannot change the conditions, which have been copied from the main item, at sub-item level. It is possible, however, to define additional conditions for each sub-item.
Prerequisites
A calculation schema, which can be altered on an individual basis in Customizing, has been supplied for the price determination.
In the vendor master record, you have set the schema group 09 (interchangeable material).
But in customizing I didnu2019t find value 09 for schema group .
Can any buddy through some light on missing pieces which need to be set?
Thanks

Hi,
Can you check few more things and tell me?
- In this exit, does XVBPA and XVBAP contains all the line items. ( main and sub items ).
- In Sales order creation time, do these table have VBELN populated when this exit triggers.
- If you modify XVBPA or XVBAP in this exit, do they get overwritten after that.
Try this code. See if it works. Let me know if you still have a problem.
DATA: wa_hvbpa LIKE vbpa,
      wa_xvbpa like vbpa.
CLEAR: wa_hvbpa, wa_xvbpa.
* check if HVBAP and VBAP line items are not same
IF vbap-posnr <> hvbap-posnr.
* read the ****-to partner from main-item
READ TABLE xvbpa INTO wa_hvbpa WITH KEY posnr = hvbap-posnr
                                          parvw = 'WE'.
IF sy-subrc = 0.
*   read the line item data for sub-item based on main item
    READ TABLE xvbap WITH KEY posnr = vbap-posnr
                              uepos = hvbap-posnr.
* See if current line is the child of that BoM parent
    IF sy-subrc = 0.
      MOVE wa_xvbpa-kunnr TO xvbpa-kunnr.
      MOVE xvbap-vbeln TO wa_xvbpa-vbeln.
      MOVE xvbap-posnr TO wa_xvbpa-posnr.
      MOVE 'WE' TO wa_xvbpa-parvw.
      MODIFY vbpa FROM wa_xvbpa.
