Displaying text in a window

[hahanottelling]

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?

[Freaky_Chris]

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.

[hahanottelling]

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.
