Vc++ MessageBox(0, "Test Message","Test",MB_OK);

1970s(1970s)

Hi there, I use the windows SDK fuction:

MessageBox(0, "Test Message","Test",MB_OK)

in VC++6. Obviously, it should work. But Vc compiler tells me I should use it like:

MessageBox(0, unsigned short * ,unsigned short *, int ) .

Can anybody tell me why?

Thanks a lot.

Error info:
TestRecord.cpp(256) :
error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'char [27]' to 'const unsigned short *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

查一下你的 build->Set Active Configuration,是不是unicode? -jackcat(wangwang); 2002-12-23 (#931379@0)
Are you using it in a class derived from a window class? -charlesdong(charlesdong); 2002-12-29 {68} (#942422@0)
If so, use :: in the front of the function to call the API function.
Yes, it's in uncode mode. I changed to debug mode, it works perfectly. I appreciate ur help. -1970s(1970s); 2002-12-31 (#945809@0)
too simple: MessageBox(0, _T("Test Message"),_T("Test"),MB_OK) -noexit(野狼); 2002-12-31 (#945828@0)
