LabVIEW one button dialog fails in filter event

Hello,
I'm using the one button dialog to provide feedback to the user in an event structure. Inside of a notify event, it works fine. I have another instance inside a filter event (Edit Cell? for a listbox). When it gets called, the dialog box appears to hang. I've noticed that if I select a window from another application (like Windows Task Manager), then come back it appears that the one button resets to the FALSE state and operates correctly. If I don't switch applications, the one button dialog is completely unresponsive.
The VI that I am running is top level, and set to Modal. I am setting the Discard? output to be TRUE in the cases where I provide the dialog. The dialog box works the first time, but fails on subsequent iterations. Perhaps the Discard? setting is affecting operation?
Thanks for your thoughts.

Can somebody decipher the online help for the one button dialog?

So I was looking at the online help for the one button dialog and there is an extra paragraph compared to the LabVIEW help.
Clicking on the link goes to a help specific to the Embedded module for the ARM microcontroller. Does this really have much to do with the one button dialog? Does it belong here?
Just wondering. I am not familiar with that module....

The same is true of the online help back to LV2009 inclusive, which (I believe) would be the first to contain the linked dialog too.

How to close a front panel using 'one button dialog'?

I wish i could use a 'one button dialog' so that the user can close the front panel when asked.
actually, i do put a 'open vi reference' followed by an 'invoke node' and then by a 'close reference' in a case true false (vi attached)
it seems that i can'ty use the option 'close FP' in my invoke node.
I am using a labview 6i version, is that possible to have this option, otherwise hoe can i achieve muy application without this invoke node??
thanks

If my component has more then one button,how to create click events

I am learning about java beans
My java class
public class ButtonClass extends JButton implements Serializable{
// ButtonHandler bh;
public ButtonClass() {
setText( "Hello world!" );
setOpaque( true );
setBackground( Color.ORANGE );
setForeground( Color.BLUE);
setVerticalAlignment( CENTER );
setHorizontalAlignment( CENTER );
// addActionListener(new ButtonHandler(new JTextArea("Hello")));
But i want to create Bean having more then one button on my bean.
But how to create event individually for each button

Do you mean how do you process each event from the buttons and know which button casued the event?
If that is what you mean then look at ButtonGroup. You can add the same mouselistener to each button and then check which one cause the event:
myButtonEvent.getButton()

Two button dialog have to press no twice

I put a 2 button dialog in an event structure. When my stop button is pressed the value changes, it enters the event structure and a two button dialog pops up that says do you really want to quit? If yes is pressed the program ends. If no is pressed the dialog box stays open. If its pressed again, then the program continues running. Essentially it does what i need it to do, keeps the program running if no is pressed but its a bit annoying to always have to click it twice. Any way to fix this?
CLA, LabVIEW Versions 2010-2013

Is it possible that you may have 2 instances of this dialog in the block diagram, one on top of the other, so you can't see there's 2 of them there? Try moving the VI icon. If not, please post your code, as it may be a race condition.

Is it possible to specify a starting FILE for the browse button dialog?

I realize I can specify a starting directory/folder PATH for the dialog window that opens when the Browse Button for a file path control is clicked.
Is there also a way to programatically preset the "File Name" field in the window that pops up? (for LV v7.1.1)

You could use a normal path control (without browse button), a browse button boolean control, openg has one. And use a value change event (in that way you can force user to use the dialog). In the event case you can use a browse function where you can set a filename.

LabVIEW PDA button appearance

I have developped an application in LabVIEW 7.0 for Pocket PC.
I need to use version 7.1 to correct some bugs and add functionalities. It seems that the appearance of boolean buttons has changed. I find out how to set background color but I have still a problem with the font. In version 7.0 (Pocket PC 2002) there was a "bold" effect on the button font. This effect is still visible on two button dialog box.
Does anybody knows how to keep this effect (which font to use, what attribute, ...)
Thanks for your help.

Hi,
I don't have a Pocket-PC but a PALM OS based PDA with LV-7.1
The button style of two buttons dialog box is not a bold one. It's a plain font.
I'll ask the question about Pocket PC specifically.
Best regards.

Add-On [X] failed with exception; Event Type:16

Hi,
I'm currently trying to create a SAP B1 Add-On using C# (Framework 3.5/VS 2008). I've done several VB.Net Add-Ons in the past but this is the first one I try to create one in C#.
Using the SDK code examples, I've managed to create an Add-On that correctly connects to UI and DI (I can create a sub-menu, set event filters and add some usertables and userfields). My sub-menu opens an XML based form in SAP B1. The first time I click on the sub-menu, my form is correctly shown. But immediately after, I get the following error in the message bar at the bottom :
Add-On [X] failed with exception; Event Type:16, in which [X] is a number (like 90003), incrementing each time I stop the Add-On in Visual Studio and restart it.
After this message occurs, I cannot display another instance of the window using the sub-menu. In fact, it seems that all Add-On activity (button click, event trapping) is disabled or ineffective. The Add-On still is running in the process tree, but no response. Only the "X" is working on the created form to close it.
I've run some tests on the code and I realized that this is happening on XML based forms (using the LoadBatchActions command to load the form) and the FormCreationParams class to create a simple form. If I put the form creation line code in comments, my Add-On still runs (I can trap events on the sub-menu click) ; I can click multiple times on the menu without a problem But as soon as I create a form, it stops responding.
It also seems that as soon as I click on another menu to open a system form, the same error occurs. If I comment the form creation line code, again I can click as often as I want without getting this error message
Can anyone help me on this one ? I can post some code depending of what you may need to check this.
Thanks !

Sorry, I've just found the problem ; it was caused by an unhanded exception !
Thanks !

Replace button dialog

I am trying to use the Find feature to locate all one button and two button dialog boxes in my VI so that I can replace them with my own message VIs.
This is a large application with many sub VIs as well.
I am having no luck finding them programatically and have to search manually.
Does anyone know of a way to find them?
Thanks

Here's a VI that will do it programatically using scripting.
Make sure you back up your project before running it though.

I can not get LabVIEW to respond to a VB6 ActiveX event

I am working with a VB6 ActiveX dll (VBtablet.dll is a wrapper for Wintab32 for a tablet interface) using LV8.2.1 and can not get it to respond to an event. I have opend the object and registered it for callback, but have had no luck in having an event generated. Is there anyway to see these events generated or at least that it has been registered? The dll has no problem working in a VB app or in Excel using a VB macro. Is there anything special that has to be in the ActiveX object to get LabVIEW to respond to it?
When I register the callback I use a control reference of the data being returned as my "user data" and in the callback VI I wire the event data into the "Value" of the control reference. I believe this is all I have to do. Any ideas would be helpfull.
Thanks,
Paul

I am able to see that events are generated from the dll, but somewhere between the ActiveX object and LabVIEW it is disconnected. Is it possible that LabVIEW is excepting these events and not allowing then into the code. The path as I see it is
dll -> WinAPI -> ActiveX -> LabVIEW
One thing this dll requires is a windows handle and I am wondering if LabVIEW itself is reads the events directly instead of ignoring them. The reason I bring it up is that the tablet works like a mouse and I am wondering if it is absorbing these commands directly and not allowing them to be passed through the ActiveX object. Like this
dll-> WinAPI -> LabVIEW
therefore the event is never generated. That is why I wish I could speak with someone at NI that could explain that process better, but it seems like there is no one at NI who knows any high level issues.
First this are not high level issues but lowest low level issues. Some of it certainly is more Windows related than LabVIEW so support from MS, as unlikely it is to get that, would be at its place. NI people are not there nor can't really help you debug your VB issues.
Second you say it is a tablet and works like a mouse, then I'm wondering if Windows is not simply claiming it as a Human Interface Device itself and not really letting you control it yourself in your VB control.

How to add one button at top of table that creates new rows each time a user clicks on it?

In the help guide, there is an example of adding buttons to each row - an Add Row and Delete Row button. I am interested in having one button at the top of the table that can add rows.

Hi,
You can create a table with a header row, where you can place your add button in one of its cells.
Then you need a script to create a new row in the buttons click event. In a table named 'Table1' with a row named 'Row1' it looks this way:
Table1._Row1.addInstance()

Stop whole program with one button

Hi, I've written a program for reading some values out of a measurement instrument. Now i want to have one button which stops the entire program no matter in which loop or which subVI the program is in. I have a subvi to make a connection to the device and i can't get out of this when he is trying to make that connection. Also the stopbutton i've used now is only read when the program is in a specific while loop. Can is solve this problem. I've attatched my program.

You will need to use global variables to communicate between VIs. Don't make it a habit since using them can lead to race conditions and synchronization problems, so I would recommend that you look into functional global variables, semaphores, notifiers and queues. The Help document in LabVIEW has detailed explanations on each one of them.
You will need to call a subVI in parallel if you want to continue with the execution of other tasks in your mainVI. I have created a quick example which shows the use of a global variable and using a subVI in parallel.
