From my understanding, whenever you need COM objects that run on STA (Single Thread Apartment) you need to specify the STAThreadAttribute to your program. That is why A's destructor is being called.

Cannot Change Thread Mode After It Is Set Coinitialize

Can you help me?? This object is responsible for set up connexion. There is no CString ListBox variable option for VC++ 2008.

My concern is how to fix with without breaking code, as there may be code out there today that is managing to mask this error. during hidden period, they should not be visible/available to the user.

Prior to using COM, the new thread must first enter an apartment by calling CoInitialize(Ex) or OleInitialize. Coinit_apartmentthreaded I have now placed the whole code in another thread & its working. class A { int *p; public : A() {p = new int;
*p = 10;} ~A () { delete p; p = NULL; printf("this is A dest \n"); } virtual a CString can cast itself to an LPCTSTR, so CListBox.AddString doesn't need an explict CString overload.

If you uncomment the line indicated, the error is completely ignored - the "getattr" for a non-existing attribute internally masks the "pending" error set by pythoncom.CoInitialize(). check my blog CPallini14-Jan-10 1:58 CPallini14-Jan-10 1:58 Actually he is getting RPC_E_CHANGED_MODE, probably one of the loaded DLLs of his application already called the function specifying a different threading model.
