    Visual Studio Express 2008 problems.

    I'm trying to use the compiler Visual Studio Express 2008, yet a sample program that worked for Dev C++ and is supposed to work with VC++.

    http://www.winprog.org/tutorial/simple_window.html.

    I've just copy pasted to get around any mistypes, but i keep getting 4 errors:

    .\first_vc.cpp(40) : error C2440: '=' : cannot convert from 'const char [14]' to 'LPCWSTR'
    .\first_vc.cpp(46) : error C2664: 'MessageBox' : cannot convert parameter 2 from 'const char [28]' to 'LPCTSTR'
    .\first_vc.cpp(57) : error C2664: 'CreateWindowExW' : cannot convert parameter 2 from 'const char [14]' to 'LPCWSTR'
    .\first_vc.cpp(61) : error C2440: 'initializing' : cannot convert from 'const char [24]' to 'LPCTSTR'
    .\first_vc.cpp(63) : error C2664: 'MessageBox' : cannot convert parameter 3 from 'const char [7]' to 'LPCTSTR'

    there seems to be some kind of conversion error like VC++ can't handle Char's.

    Thanks for any help

    It is because you should use unicode. But you are using ASCII. You may change its settings.

    See http://msdn2.microsoft.com/en-us/lib...tz(VS.80).aspx

    Rather than
    char message[] = "hello";

    You would say
    _TCHAR message[] = _TEXT("hello"); // _T() is a shorter macro for _TEXT()

    Or
    printf("hello");
    would be
    _tprintf(_T("hello"));

    If you use these macros correctly, then your code will compile in ASCII or UNICODE mode.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
