Noobie can't add a menu to the Windows form.
« on: May 21, 2011, 04:28:42 am »
I've tried this both in Dev-C++ and CodeBlocks with the same result - compiles fine, the form shows, but no menu (I'm using WS_OVERLAPPEDWINDOW, hope that's correct).

Code
#define IDM_FILE_EXIT_CONST 4000
IDR_MENU1 MENU
BEGIN
    POPUP "File"
    BEGIN
        MENUITEM "Exit",                        IDM_FILE_EXIT_CONST
    END
END





I've tried a number of different ways (both separately and combined).
For example I've tried this

  wincl.lpszMenuName = MAKEINTRESOURCE(IDR_MENU1);

I've also tried using LoadMenu() to create an HMENU which I pass into the CreateWindowEx call. Again, compiles fine, form shows, but no menu.

I've also tried calling SetMenu() after the call to CreateWindow. Again, the form shows, but no menu.  Here's the complete code.
Code
#define IDR_MENU1                       101
#include <windows.h>
#include <winuser.h>


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

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

int WINAPI WinMain (HINSTANCE hThisInstance,
                    HINSTANCE hPrevInstance,
                    LPSTR lpszArgument,
                    int nFunsterStil)

{
    HWND hwnd;               /* This is the handle for our window */
    MSG messages;            /* Here messages to the application are saved */
    WNDCLASSEX wincl;        /* Data structure for the windowclass */

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure;      /* This function is called by windows */
    wincl.style = CS_DBLCLKS;                 /* Catch double-clicks */
    wincl.cbSize = sizeof (WNDCLASSEX);

    /* Use default icon and mouse-pointer */
    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = MAKEINTRESOURCE(IDR_MENU1);
    wincl.cbClsExtra = 0;                      /* No extra bytes after the window class */
    wincl.cbWndExtra = 0;                      /* structure or the window instance */
    /* Use Windows's default color as the background of the window */
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
        return 0;
HMENU oMenu;
oMenu =  LoadMenu(hThisInstance, MAKEINTRESOURCE(IDR_MENU1));


    /* The class is registered, let's create the program*/
    hwnd = CreateWindowEx (
           0,                   /* Extended possibilites for variation */
           szClassName,         /* Classname */
           "Windows App",        /* Title Text */
           WS_OVERLAPPEDWINDOW, /* default window */
           CW_USEDEFAULT,       /* Windows decides the position */
           CW_USEDEFAULT,       /* where the window ends up on the screen */
           544,                 /* The programs width */
           375,                 /* and height in pixels */
           HWND_DESKTOP,        /* The window is a child-window to desktop */
             oMenu,
                    hThisInstance,       /* Program Instance handler */
                 NULL           /* No Window Creation data */
           );


    /* Make the window visible on the screen */
    ShowWindow (hwnd, nFunsterStil);
    SetMenu(hwnd, oMenu);

    /* Run the message loop. It will run until GetMessage() returns 0 */
    while (GetMessage (&messages, NULL, 0, 0))
    {
        /* Translate virtual-key messages into character messages */
        TranslateMessage(&messages);
        /* Send message to WindowProcedure */
        DispatchMessage(&messages);
    }

    /* The program return-value is 0 - The value that PostQuitMessage() gave */
    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;
}

I got it working. Some of the code that failed in Dev-C++ seems to be working now in CodeBlocks.
