How do I get the sequence context from TestStand API?

[InquiringMind]

I am trying to terminate an execution by clicking a button in CVI. Just a simple button, but I don't know how to get the SequenceContext. Here is what I have:

int CVICALLBACK TerminateButton (int panel, int control, int event,
  void *callbackData, int eventData1, int eventData2)
{
 
 switch (event)
 {
  case EVENT_COMMIT:
 
   CAObjHandle seqContext;
   TSObj_Execution excObj;
   ERRORINFO errorInfo = { 0, 0, "", "", "", 0, 0 };
   ErrMsg errMsg = "";
   int error = 0;
     
  
   tsErrChk(TS_SeqContextGetExecution (seqContext, NULL, &excObj));         
   tsErrChk(TS_EngineTerminateAll (seqContext, NULL));
   QuitUserInterface(0);
   
   break;
 }
Error:
  return 0;
}

I am not sure how you are getting to the TestStand Engine.  Did you place an ActiveX control object from the TestStand Engine Class, or lanch testand using TS_NewEngine which gives you a Handle to the TestStand Engine.  You want to use that in your call to TS_EngineTerminateAll.

ex

{ 

     CAObjHandle engineObj = 0;

      ERRORINFO   errorInfo;

     TS_NewEngine(NULL, &engineObj);   // Creating new instance of TestStand 

 

...

   TS_EngineTerminateAll(engineObj, &errorInfo);

}

If you placed an ActiveX control on a panel in your uir, you can get the handle by the following:

 GetObjHandleFromActiveXCtrl(panel,  PNL_ENGINE_CTRL,  &engineObj )

// panel is a handle to the panel

// PNL_ENGINE_CTRL is the control ENGINE_CTRL on panel PNL.

Hope this helps.
