Question

Attempting to disable BSTR caching:

SetOaNoCache(); 

VC++ compiler build output:

• 'SetOaNoCache': identifier not found

Don’t want to use:

• OANOCACHE=1

Question:

• Where is SetOaNoCache defined – header file?

Answer 1

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'); if (hLib != NULL) { SETOANOCACHE SetOaNoCache = (SETOANOCACHE)GetProcAddress(hLib, 'SetOaNoCache'); if (SetOaNoCache != NULL) SetOaNoCache(); FreeLibrary(hLib); } }
