dll - 如何在不同编译器的另一个 DLL 启动的 dll 中使用 WBEM？

Question

我有一个使用 WBEM 由 VC6 编译的工作 DLL(A)。我想从另一个DLL（B：由VC2013编译）调用DLL（A）中的函数。它在 IWbemLocator :: ConnectServer() 上崩溃。

And I have done some testing followed:
EXE compiled by VC6 - > DLL(A)  OK
EXE compiled by VC2013 - > DLL(A)  OK
EXE compiled by VC2013 - > DLL(B) - > DLL(A)  crash
I don't why, any one can give me some advise? Thank you very much!
