You might be using unicode build( which is default in vs2005 and later ). so should pass unicode string to MessageBox() function. To convert your string to unicode. use _T macro. MessageBox( _T("This is my first Visual C++ Application!"));

Try using

MessageBox(_T("This is my first Visual C++ Application!"));

it should work

You are building for Unicode and therefore trying to pass an ANSI string to an API which expects an Unicode string. Include all your literal strings within the TEXT macro.

MessageBox(_T("This is my first Visual C++ Application!")); The _T macro automatically emits an ANSI or an Unicode string (by prefixing nothing if building for MBCS or by prefixing L to the literal string if building for Unicode) These links may help you further to understand about string data types: The Complete Guide to C++ Strings, Part I - Win32 Character Encodings[^] The Complete Guide to C++ Strings, Part II - String Wrapper Classes[^] This might help you with International programming and Unicode: International programming[^]
