Handling exceptions in different units

Forgive me for posting twice. But I have the next problem...



I successfully cought exceptions caused by application's crash. Here this the code sample where I try to terminate process (if necessary) and stop test item run.





function IsProcessExist()

{

  var ProcessName = Project.Variables.ProcessName;

  Log.Message("Checking process existance");

  var ProcessExistance = Sys.WaitProcess(ProcessName, 0).Exists;

  Log.Message("Process existance is checked");

  return ProcessExistance;

}



function Terminate(Exception)

{

  var ErrorMessage = new String();

  if (arguments.length == 0)

    var ErrorMessage = "Unknown error or exception";

  else

  {

    if (typeof(Exception) == "object")

      ErrorMessage = Exception.description;

    else

      ErrorMessage = Exception;

  }

    

  var ProcessName = Project.Variables.ProcessName;

  var TerminationTimeOut = Project.Variables.TerminationTimeOut * 1000;     // in milliseconds

 

  Log.Error("Termination reason: " + ErrorMessage);

 

  /* Checking application's process for existance */

  if (!IsProcessExist())

  {

    Log.Message("Application's process is already terminated");

  }

  else

  {

    Log.Message("Attempt to terminate process...");

    TestedApps.ScanMagic.Terminate();       // sending instructions to terminate process

  }

 

  aqUtils.Delay(TerminationTimeOut);

  Log.Message("Stopping test case execution...");

  Runner.Stop(true);          // stopping current test only

}





This one works fine in most cases but sometimes application crashes with "Microsoft Visual C++ Runtime Library Error" window. According to received logs the application's process is already terminated but any actions, for example, aqUtils.Delay(...) or Runner.Stop(true) can't be performed before I activate any other application or press Windows' "Start" button manually. Only after this script continue it's work and stops.



I tried to simulate "Start" button pressing, and received click events in my log...but in real nothing has changed - application's window and modal error window described higher are still preventing normal script execution...



What's the reason? Can I solve this problem by any methods?



Thanks...
