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.
