    Re: 'WM_UNICHAR' was not declared in this scope

    MSDN says:

    Declared in Winuser.h, include Windows.h

    But it also appears that you have to target your application fror 5.1 (XP) minimum:

    #if(_WIN32_WINNT >= 0x0501)
    #define WM_UNICHAR 0x0109
    .....

    You may have pre-XP header files. The usual thing to do in this case is to download the latest SDK from Microsoft.

    I don't know enough about WM_UNICHAR to speak authoritatively, but based on the documentation I would guess that the message is simply not implemented in pre-XP operating systems.

    Sorry, UNICODE_NOCHAR is a bit of a mystery to me. There's only one reference to it on MSDN (in a blog post) and I don't have time to sort through the Google results.

    I don't know what to tell you. I have Windows Server 2003 R2 SDK and it's defined in winuser.h just like I showed above. Do you know which SDK you are using?

    I admit that I know nothing about gcc, but Microsoft is the only official source for Windows headers.

    and you are sure that windows headers will work with GCC? i think they are designed for VC++ only.

    Re: 'WM_UNICHAR' was not declared in this scope

    As I said, I know nothing of gcc, but if it can create Windows applications then I would assume that it can use Microsoft's headers. And I can tell you that if gcc supplies Windows headers then they must originate with Microsoft. They are redistributable after all. Of course, gcc could modify them for its own purposes but I'm not sure that would pass a license test.

    Why are you positive that your headers are post-XP? It sound to me like they aren't. Just because you acquire something after XP has been released doesn't mean that it is XP compatible. gcc could be supplying very old headers.

    Another thing to consider is that maybe in your case you could just define WM_UNICHAR yourself as show above (0x109). You must realize that the definition in the header is only for the benefit of your program. Any post-XP operating system will send the WM_UNICHAR message regardless of whether your program knows about it. If that message is the only thing you are missing then just define it and see what happens.

    There's always the chance that the number I provided will be incompatible in the future, but I've never seen any indication that once a Windows message has been defined that it ever gets changed.

    Re: 'WM_UNICHAR' was not declared in this scope

    You may still want to consider my advice about defining WM_UNICHAR yourself, but I know that many here also use gcc. Does anyone else have an idea of what is happening? Why don't the gcc headers define this message?
