CVI Custom User Interface with TestStand

[angelglezg]

Good day community, I'm new in using TestStand with Labwindows/CVI. 

I've got an error using TestStand API triying to open a sequence file from an absolute path. 

Further I want to use some UI Teststand controls, what is the correct way to use thems, and what I need to do to use thems.

Thank you, best regards.

Hello,

The control that is visible needs to be connected to the Application Manager. I guess it is not connected to anything ? Do not hesitate to attach a code snippet with your post, that allow other users to reproduce your issue.

A good starting point are the Example User Interfaces that are shipped with TestStand. There are proposed for 5 differents developpement languages, C++, C#, LabVIEW, LabWindows/CVI and VB .Net.

There is also ressources on the NI website :

• Working with the TestStand Simple User Interface - LabWindows/CVI
• Creating Custom User Interfaces
• TestStand User Interface Development Best Practices

Hope this helps,

Hello Mathieu thanks for your repply, it was very helpul!.

Now I got a new error triying to shutdown the application manager, I attached my main code as you suggested to me:

/* Main code */
int main(int argc, char *argv[])
{
	int		error = 0;
	long	exitCode = 0;

	nullChk( InitCVIRTE(0, argv, 0));	// initialize CVI runtime engine

	// load the panel for the main window from the .UIR file
	errChk( gMainWindow.panel = LoadPanelEx (0, "TestExec.uir", MAINPANEL, __CVIUserHInst));
	
	// get ActiveX ctrl handles, register ActiveX event callbacks, and connect TestStand controls
	errChk( SetupActiveXControls());

	errChk( InstallMainCallback(MainCallback, 0, 0));	

	// make a handle to engine conveniently accessible
	tsErrChk( TSUI_ApplicationMgrGetEngine(gMainWindow.applicationMgr, &errorInfo, &gMainWindow.engine));

	// start up the TestStand User Interface Components. this also logs in the user
	tsErrChk( TSUI_ApplicationMgrStart(gMainWindow.applicationMgr, &errorInfo));
	
	// open sequence file
	tsErrChk( TSUI_ApplicationMgrOpenSequenceFile(gMainWindow.applicationMgr, &errorInfo, ".\\sequences\\callingStringStdOut.seq", &file));
	
	// entrypoint execution
	tsErrChk( TSUI_SequenceFileViewMgrGetExecutionEntryPoints(gMainWindow.sequenceFileViewMgr, &errorInfo, &EntryPoints));
	tsErrChk( TSUI_EntryPointsGetItem(EntryPoints, &errorInfo, CA_VariantULong(0), &EntryPoint));
	tsErrChk( TSUI_EntryPointRun(EntryPoint, &errorInfo, CA_DEFAULT_VAL, &EntryPointExecution));
	
	// display window and process user input until application exits
	errChk( DisplayPanel(gMainWindow.panel));
	errChk( RunUserInterface());

	errChk( TSUI_ApplicationMgrGetExitCode(gMainWindow.applicationMgr, &errorInfo, &exitCode));

Error:
	if (gMainWindow.panel > 0)
		DiscardPanel(gMainWindow.panel);
	DisplayError(error);
	return exitCode;
}


/*Close application */
static int ExitApplication(void)
{
	int		error = 0;
	VBOOL	canExitNow;

	tsErrChk( TSUI_ApplicationMgrShutdown(gMainWindow.applicationMgr, &errorInfo, &canExitNow));
	
	if (canExitNow)
		QuitUserInterface(0);
Error:
	DisplayError(error);
	return canExitNow ? TRUE : FALSE;
}

This message occurs when I close my application:
