GUI problem?

[Black Magic]

Hey,
I decided to make a little visit to Winprog and decided to go on the page "Menus and Icons" and so i copied and pasted the code from the website to give me..

#include "resource.h"

IDR_MYMENU MENU
BEGIN
    POPUP "&File"
    BEGIN
        MENUITEM "E&xit", ID_FILE_EXIT
    END

    POPUP "&Stuff"
    BEGIN
        MENUITEM "&Go", ID_STUFF_GO
        MENUITEM "G&o somewhere else", 0, GRAYED
    END
END
IDI_MYICON ICON "Console.ico"

And i made my own resource.h which has..

#define IDR_MYMENU 101
#define IDI_MYICON 201

#define ID_FILE_EXIT 9001
#define ID_STUFF_GO 9002

The problem is that I get 2 Errors:

3 D:\C++ Code\Gui.cpp expected unqualified-id before numeric constant
3 D:\C++ Code\Gui.cpp expected `,' or `;' before numeric constant

Please help.

Could you post the Gui.cpp file?

Here you go.

Here you go.

You are trying to define the application's resources in the .cpp file. That cannot be done. Instead,

• save the Gui.cpp as e.g.
• resource.rc
• (= resource script)

• add the
• resource.rc
• file to your project

• then you might copy/paste the following code into Gui.cpp (it's pretty much standard Dev-C++ Win Gui application code). Assuming that you have created a Win32 GUI project.

• then compile and run

#include <windows.h>
#include "resource.h" // <- needed for the menu ID (IDR_MYMENU)

/*  Declare Windows procedure  */
LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

/*  Make the class name into a global variable  */
char szClassName[ ] = "WindowsApp";

                    HINSTANCE hPrevInstance,
                    LPSTR lpszArgument,
                    int nFunsterStil)

{
    HWND hwnd;               /* This is the handle for our window */

           CW_USEDEFAULT,       /* where the window ends up on the screen */
           544,                 /* The programs width */
           375,                 /* and height in pixels */

    while (GetMessage (&messages, NULL, 0, 0))
    {
        /* Translate virtual-key messages into character messages */
        TranslateMessage(&messages);

    return messages.wParam;

/*  This function is called by the Windows function DispatchMessage()  */

LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)                  /* handle the messages */
    {
        case WM_DESTROY:
            PostQuitMessage (0);       /* send a WM_QUIT to the message queue */
            break;
        default:                      /* for messages that we don't deal with */
            return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
}

Note that if you don't have the console.ico icon specified in the .rc file, you can comment out the line specifying the icon resource, i.e. // IDI_MYICON ICON "Console.ico" Note also that although the menu appears, it is non-functional since there are no related menu command handlers ...
