Can anyone help me with displaying text in a C++ window? I've read the chapter 9 at winprog but it makes no sense to me. here's the code I'm using:

#include <windows.h>
#include "resource.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 */
    HMENU hMenu, hSubMenu;
    HICON hIcon, hIconSm;
    hMenu = CreateMenu();

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpszMenuName  = MAKEINTRESOURCE(IDR_MYMENU);
    wincl.hIcon  = LoadIcon(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MYICON));
    wincl.hIconSm  = (HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MYICON), IMAGE_ICON, 16, 16, 0);
    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_WARNING);
    wincl.hIconSm = LoadIcon (NULL, IDI_WARNING);
    wincl.hCursor = LoadCursor (NULL, IDC_CROSS);
    wincl.lpszMenuName = NULL;                 /* No menu */
    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) GetStockObject (WHITE_BRUSH);

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
        return 0;

    /* The class is registered, let's create the program*/
    hwnd = CreateWindowEx (
           0,                   /* Extended possibilites for variation */
           szClassName,         /* Classname */
           "Windows App",       /* Title Text */
           WS_VISIBLE, /* 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 */
           NULL,        /* The window is a child-window to desktop */
           NULL,                /* No menu */
           hThisInstance,       /* Program Instance handler */
           NULL                 /* No Window Creation data */
           );

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

    /* 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_CREATE:
    {
        HMENU hMenu, hSubMenu;
        HICON hIcon, hIconSm;
        hMenu = CreateMenu();

        hSubMenu = CreatePopupMenu();
        AppendMenu(hSubMenu, MF_STRING, ID_FILE_EXIT, "E&xit");
        AppendMenu(hMenu, MF_STRING | MF_POPUP, (UINT)hSubMenu, "&File");

        hSubMenu = CreatePopupMenu();
        AppendMenu(hSubMenu, MF_STRING, ID_STUFF_GO, "&Go");
        AppendMenu(hMenu, MF_STRING | MF_POPUP, (UINT)hSubMenu, "&Stuff");

        SetMenu(hwnd, hMenu);
}
    break;
    
    case WM_COMMAND:
            switch(LOWORD(wParam))
            {
                case ID_FILE_EXIT:
return 0;
                break;
                case ID_STUFF_GO:

                break;
            }
        break;


        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 just want to have text in the space under the menu... Is there any simple way to add it?

What do you mean by 'Text'? As in an editable text control? or just writing painted onto the windows?

there is a big difference.

I mean just text like this, that shows up on the screen. Not editable or anything, just simple text. Thx for replying.

Add this message handler to your windows proc:

case WM_PAINT:
  {
    PAINTSTRUCT ps;
    HDC hdc = BeginPaint( hwnd, &ps );
    TextOut( hdc, 0 /* X */, 0 /* Y */, "Blah de blah de blah", 20 /* Number of chars */);
    EndPaint( hwnd, &ps );
  }
  break;

Should be enough to get you started - though google would have been even better.

Thank you so much, that's exactly what I needed. I tried google many times, but could not find anything!

I get "undefined reference to TextOut@A20" when I try that suggestion, William Hemsworth.
