MessageBoxW and converting to LPCWSTR

[sawerr]

Hi MessageBox(NULL, "Hello World", "Message Box Title -- Hello World", MB_OK); Error: error C2664: 'MessageBoxW' : cannot convert parameter 2 from 'const char [12]' to 'LPCWSTR' IDE:VS2005 I don't understand why it gives this error. Can you please tell me what the problem is and how i can solve it. Thanks

hi, L"Hellow World" in the MessageBox.

The default project charset setting in VS2005 is using UNICODE, so the MessageBox maps to MessageBoxW, which takes unicode strings as its input. You can 1. changing your project's setting from using UNICODE to MBCS 2. enclose each of the string appeared in your source files with _T(). Or you can do both. The _T macro will map the string to wide char string constant if the project is set to use UNICODE, and will map the string to normal ANSI string constants if the project is set to use MBCS charset.

What does this mean? _T() macro is defined in tchar.h; But again finally expands to L""
