这两个函数的声明虽然是在comutil.h中,但即使在用到的cpp文件中包含了comutil.h头文件,也是会在链接阶段报错,说是找不到这两个函数的符号. 解决办法就是#include<comdef.h>.据我猜测,comdef.h中包含了lib库的引用.
我的用法 -- _com_util::ConvertStringToBSTR(); char* pTemp; CString csTemp; pTemp = _com_util::ConvertBSTRToString(bsVal); csTemp = pTemp; delete pTemp; pTemp = NULL; // 这是我们公司的一位高手的最安全的用法 // 对于ConvertStringToBSTR不需要...

String is converted usingMultiByteToWideChar() If conversion failed, raise COM exception. And nowSysAllocString()is called. I hope MS coders do not use that function for their product development, otherwise we can crash almost every product they have produced according to this_com_util::ConvertSt...
