Question

I have a vc++ 2005 dialog based application, where I use a worker thread to do some background processing.

The worker thread is implemented as a global function in the dialog class

I am able to access the variables of the dialog class inside the worker thread but I am not able to get some of their their values correctly inside the worker thread.

For example, I have initialized a COM object (using CoInitilize) in the dialog class, but I am not able to access its latest value. I tried declaring them globally but still I couldn’t get their values inside the thread.

Please tell me how can I access COM objects inside worker threads

Thanks.

Answer 1

CoInitialize function must be called in every thread that you starts, if you want to use any COM object inside it. Check MSDN documentation of this function. Please also remember to deinitialize COM before exiting from thread.
