    Dialog button& .rc file problem

    Hello,

    I'm trying to create a program that creates a dialog when you click on a certain menu option.
    Now, the problem is my compiler doesn't work well with resource files.

    So, is it possible to create a dialog from within the program, without haveing to create the template in a resource file? I know it's possible to do it with menus, but not sure if you can do it with dialogs.

    If it is possilbe could someone show me an example of what to put when using it?

    EDIT:
    Ok I got this problem solved except one minor thing, I keep getting a parse error on line three of the following .rc file:
    Code:
    IDD_ABOUT DIALOG DISCARDABLE  0, 0, 239, 66 
    STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
    FONT 8, "MS Sans Serif" 
    CAPTION "ORANGE!!!!"
    BEGIN 
        DEFPUSHBUTTON   "OK",IDOK,174,18,50,14 
        PUSHBUTTON      "Cancel",IDCANCEL,174,35,50,14 
        GROUPBOX        "About this program...",IDC_STATIC,7,7,225,52 
        CTEXT           "An example program showing how to use Dialog Boxes\r\n\r\nby theForger", 
                        IDC_STATIC,16,18,144,33 
    END
    No matter wich line is line three there is a parse error. Any ideas what it could be?

    >>So, is it possible to create a dialog from within the program, without haveing to create the template in a resource file?<<

    Yes, but it's a major pain. Use memory templates and create the dialog with either CreateDialogIndirectParam or CreateDialogIndirect (which just calls CreateDialogIndirectParam anyway).

    Still, glad to see you're persevering with windres.

    >>Any ideas what it could be?<<

    When using windres (mingw windows resource compiler) always make sure your resource script has something like the following at the top:
    Code:
    #include <windows.h>
    #include "resource.h" /*resource header contains defines for YOUR controls*/
    #if !defined IDC_STATIC
    #define IDC_STATIC -1
    #endif

    Ok that helped for that error but now I get a parse error on the following:
    Code:
    GROUPBOX        "About this program...",IDC_STATIC,7,7,225,52

    Sorry, my fault - a typo in the above. IDCSTATIC -1 should be IDC_STATIC -1. I've fixed it in the original post.

    Ok now that I have it compileing, i have *yet* another problem =(
    The dialog doesnt want to show up (I get a -1 return value), here is the code:
    Main.cpp:
    Code:
    #include <windows.h>
    #include "resource.h"
    const char g_szClassName[] = "myWindowClass";
    
    BOOL CALLBACK AboutDlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
    {
        switch(Message)
        {
            case WM_INITDIALOG:
    
            return TRUE;
            case WM_COMMAND:
                switch(LOWORD(wParam))
                {
                    case IDOK:
                        EndDialog(hwnd, IDOK);
                    break;
                    case IDCANCEL:
                        EndDialog(hwnd, IDCANCEL);
                    break;
                }
            break;
            default:
                return FALSE;
        }
        return TRUE;
    }

    END
    Is there something I can't see thats would result in an error? Sorry for the constant questions but I just started this yesterday and am getting a bit confused with these tuturials.
