SetOaNoCache 在哪里定义? [英] Where is SetOaNoCache defined?

问题描述

尝试禁用 BSTR 缓存:

Attempting to disable BSTR caching:

SetOaNoCache();

VC++ 编译器构建输出:

• 'SetOaNoCache':未找到标识符

不想想使用:

• OANOCACHE=1

问题:

• SetOaNoCache 定义- 头文件?

• Where is SetOaNoCache defined - header file?

推荐答案

它没有在头文件中定义，它在 OLEAUT32.dll 中.你可以这样称呼它:

It is not defined in a header file, it is in OLEAUT32.dll. You can call it like this:

typedef int (*SETOANOCACHE)(void);

void DisableBSTRCache(){HINSTANCE hLib = LoadLibrary("OLEAUT32.DLL");如果(hLib ！= NULL){SETOANOCACHE SetOaNoCache = (SETOANOCACHE)GetProcAddress(hLib, "SetOaNoCache");如果 (SetOaNoCache != NULL)SetOaNoCache();自由图书馆(hLib)；}}

void DisableBSTRCache() { HINSTANCE hLib = LoadLibrary("OLEAUT32.DLL"); if (hLib != NULL) { SETOANOCACHE SetOaNoCache = (SETOANOCACHE)GetProcAddress(hLib, "SetOaNoCache"); if (SetOaNoCache != NULL) SetOaNoCache(); FreeLibrary(hLib); } }
