Are you sure the error is for this call?
It might be that you have set strings to Unicode or vice-versa. The function takes 3 parameters but two have defaults.

By default any new project you create with VC 2005 has an option to use UNICODE text. Simply use L modifier for your strings in quotes:

AfxMessageBox (L"Hello!");

Yes , I got the right solution . This is thank to your experience . Thank and have good weekend !
