[python-win32] (no subject)

[徐仲谨]

Hi ladies/gentlemen,

What I do now is based on Motorola Scan Bar Code SDK to do some development.

SDK is COM thing. there are API Commands and API Events as they called.

 

API Commands¡¯ development is finished. But Events no, I tried, but failed.
Could u give some help ~ ~.

Thank you.

<CODE>

from pythoncom import *

from win32com.client import *

drv = win32com.client.Dispatch("CoreScanner.CoreScanner",clsctx =
CLSCTX_ALL)

Then I can use the method/attribute, such as Open, Close and so on. Goooood.

 

class LocalScanEvent:

    def OnBarcodeEvent(self, eventType=0, pscanData=pythoncom.Empty):

        print "@@@@@@@@@@@@"

 

evt = = DispatchWithEvents("CoreScanner.CoreScanner", LocalScanEvent)

Now prblem appears. I can¡¯t get the LocalScanEvent work. When I debug the
dispatch, it always go to BASECLASS.

How could I do? Please help out. Thank you.

 

P.S. BASECLASS ¨C it is shows in attachment,¡± class
ICoreScanner(DispatchBaseClass):¡± .

 

Best regards,
