python call teststand engine

[gxgxn97]

I use python and teststand engine to customize solution.But I have some questions about it. 1,code as below: tsEngine = win32com.client.Dispatch("TestStand.Engine.1") print "TestStand %s.%s ready" % (tsEngine.MajorVersion, tsEngine.MinorVersion) tsEngine.UIMessagePollingEnabled = True sequencePath = os.path.join(cwd, 'MySequence.seq') seqFile = tsEngine.GetSequenceFileEx(sequencePath) execution = tsEngine.NewExecution(seqFile, "MainSequence", seqFile, False, 0) execution.WaitForEndEx(60000) execution = None released = tsEngine.ReleaseSequenceFileEx(seqFile, 0x4) seqFile = None #coreleased = tsEngine.ReleaseSequenceFileEx() tsEngine.ShutDown(True) tsEngine = None ## Execution freezes here 2,I need to use UImessage to get pass/fail result of "MySequence.seq".So the first step,I set "tsEngine.UIMessagePollingEnabled = True".But python print these error: Traceback (most recent call last): File "D:\TS_solution\CallTestStand.py", line 39, in released = tsEngine.ReleaseSequenceFileEx(seqFile, 0x4) File "", line 3, in ReleaseSequenceFileEx pywintypes.com_error: (-2147352567, '\xb7\xa2\xc9\xfa\xd2\xe2\xcd\xe2\xa1\xa3', (0, u'TSAPI', u"Unable to unload sequence file 'MySequence.seq' because it is in use, possibly because it is executing.", None, 0, -17213), None) 3,I comment "tsEngine.UIMessagePollingEnabled = True",then teststand pop-up warning windows,show as below: References to PropertyObjects were not released properly.

I use python and teststand engine to customize solution.But I have some questions about it.
1,code as below:

tsEngine = win32com.client.Dispatch("TestStand.Engine.1") 
print "TestStand %s.%s ready" % (tsEngine.MajorVersion, tsEngine.MinorVersion) 
tsEngine.UIMessagePollingEnabled = True 
sequencePath = os.path.join(cwd, 'MySequence.seq') 
seqFile = tsEngine.GetSequenceFileEx(sequencePath) 
execution = tsEngine.NewExecution(seqFile, "MainSequence", seqFile, False, 0) 
execution.WaitForEndEx(60000) 
execution = None 
released = tsEngine.ReleaseSequenceFileEx(seqFile, 0x4) 
seqFile = None 
tsEngine.ShutDown(True) 
tsEngine = None ## Execution freezes here 

2,I need to use UImessage to get pass/fail result of "MySequence.seq".
So the first step,I set "tsEngine.UIMessagePollingEnabled = True".
But python print these error:

Traceback (most recent call last): File "D:\TS_solution\CallTestStand.py", 
line 39, in released = tsEngine.ReleaseSequenceFileEx(seqFile, 0x4) File "", 
line 3, in ReleaseSequenceFileEx pywintypes.com_error: (-2147352567, '\xb7\xa2\xc9\xfa\xd2\xe2\xcd\xe2\xa1\xa3', (0, u'TSAPI', u"Unable to unload sequence file 'MySequence.seq' because it is in use, possibly because it is executing.", None, 0, -17213), None)

3,I comment "tsEngine.UIMessagePollingEnabled = True",
then teststand pop-up warning windows,show as below:

4,How can I call Teststand API--UImessage class through Python?

Hi, have you find a solution for this issue?

I am currently facing the same problem.

[NicolasH.Deltadore]

It's probably a bit late now but I had to create a handler for UI messages in python with the win32com module. So I'll share my solution in case it can help anyone...

All you need to do is call the "WithEvents" function of win32com.client like this : 

tsEngine = win32com.client.Dispatch('TestStand.Engine.1')
tsEngineEvent = win32com.client.WithEvents(tsEngine, EngineEventHandler)

EngineEventHandler being a class dedicated to the handling of the messages  : 

class EngineEventHandler:
    def OnUIMessageEvent(self, uiMsgEvent):
        ...

It could probably also work with the DispatchWithEvent function. 

Although technically this is more a win32com question than a Teststand API one. And I guess this is not exactly the place to ask this.
