如果COM不是线程安全的，那么使用进程

hg写道：

实际回溯会有所帮助。

猜测，当在一个线程中使用COM

时，你需要调用pythoncom.CoInitialize和

CoUninitialize your。

I have an application which uses COM ''s Dispatch to create a COM based
object. Now I need to upgrade the application to a threaded one. But
its giving an error that COM and threads wont go together. Specifically
its an attribute error at the point where COM object is invoked. Any
pointers please??????

If COM is not thread safe, then use processes

An actual traceback would help.
At a guess, when using COM in a thread
you need to call pythoncom.CoInitialize and
CoUninitialize yourself.
