wait until execution ends

[Olfa]

Hello,

I am using TestStand API in CVI to run a test sequence. I want the button start to be dimmed during the execution, so I wrote these lines: 

SetCtrlAttribute(panel, PANEL_COMMANDBUTTON, ATTR_DIMMED, TRUE);

TS_NewEngine (NULL, &lEngine));
TS_EngineGetProperty (lEngine, &errorInfo, TS_EngineGlobals, CAVT_OBJHANDLE, &stationGlobalsHandle));

TS_EngineGetSeqFileEx (lEngine, &errorInfo, "SequenceFile1.seq",TS_GetSeqFile_OperatorInterfaceFlags, TS_ConflictHandler_UseGlobalType,&lCurrentSequenceFile ));

TS_SeqFileGetFileGlobalsDefaultValues (lCurrentSequenceFile,&errorInfo, &fileGlobalsHandle);

TSerrChk( TS_EngineNewExecution (lEngine, &errorInfo, lCurrentSequenceFile,"MainSequence", modelSeqFile, VFALSE,TS_ExecTypeMask_Normal, CA_DEFAULT_VAL, CA_DEFAULT_VAL, CA_DEFAULT_VAL, &lCurrentExecution));
TS_ExecutionWaitForEndEx(lCurrentExecution,&errorInfo, INFINITE,TRUE,CA_DEFAULT_VAL,CA_DEFAULT_VAL,&end);

SetCtrlAttribute(panel, PANEL_COMMANDBUTTON, ATTR_DIMMED, FALSE);

But it's not working, the sequence is not even executed and the button remains dimmed.

If anyone can help me I would appreciate it. 

Thank you

There are several flaws in your approach:

• You are not using Manager Controls
• You are using WaitForEndEx which is documented as This method is not meant to be used by a user interface or sequence editor, as it does not process UIMessages. Instead, use this method from a step to synchronize with another execution. Remove this from your UI code!
• The default visible TestStand button provides properties. Use them to do what you want.

thanks,
