D3DAPP.cpp problems

Could you be a little more specific with the error and it will help us help you out.

Check your include paths and make sure the paths for the version of the SDK you installed are BEFORE the default VC++ paths.

The error is

It compiled fine when I first installed it, and the files have always maintained read only status, meaning I couldn''t have changed it. I can''t figure out how else it would bave been changed.

The DMBoids example compiles, and I think it uses D3DAPP, so I don''t know what the problem is.

A bit off topic, due to circumstances beyond my control the debate in the lounge passed its statute of limitations, so if anyone is interested in continueing a new thread will have to be started.

I got to thinking. Since it''s a problem compiling would it be better off in the programming board, or is it in the right place since it deals with DX common files?

If it would be better served in the programming forum could an administrator please move it there (if there are rules against double posting, which would prevent me from posting this there)?

Don''t worry about that for the time being. If it needs moving, I''ll move it.

Could you paste the line of code that it''s having problems with (line 1225 of d3dapp.cpp)?

    // Prompt the user to change the mode

    if( IDOK != DialogBoxParam( (HINSTANCE)GetModuleHandle(NULL),
                                MAKEINTRESOURCE(IDD_SELECTDEVICE), m_hWnd,
                                SelectDeviceProc, (LPARAM)this ) )
        return S_OK;

Like I said, it has always been read only, so I don''t know how it could have been changed.

Hmm... how about the function prototype for SelectDeviceProc?

I''m going to take a guess and say that the calling convention is set to an unusual value in the project settings.

DialogBoxParamA(
    HINSTANCE hInstance,
    LPCSTR lpTemplateName,
    HWND hWndParent ,
    DLGPROC lpDialogFunc,
    LPARAM dwInitParam);
WINUSERAPI

How do you set the calling convention for a project? I should probably know that by now, but none of my books cover it.

Sorry to "necro", but since I didn''t get a reply is it safe to assume that the only way to fix it is to start with a fresh install?
