Np output window

Why does the following code not show the output window??

Code:

---

#include <windows.h>

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
                    PSTR szCmdLine, int iCmdShow)
{
    static TCHAR szAppName[] = TEXT ("Typer") ;
    HWND        hwnd ;
    MSG          msg ;
    WNDCLASS    wndclass ;
   
    wndclass.style        = CS_HREDRAW | CS_VREDRAW ;
    wndclass.lpfnWndProc  = WndProc ;
    wndclass.cbClsExtra    = 0 ;
    wndclass.cbWndExtra    = 0 ;
    wndclass.hInstance    = hInstance ;
    wndclass.hIcon        = LoadIcon (NULL, IDI_APPLICATION) ;
    wndclass.hCursor      = LoadCursor (NULL, IDC_ARROW) ;
    wndclass.hbrBackground = (HBRUSH) GetStockObject (WHITE_BRUSH) ;
    wndclass.lpszMenuName  = NULL ;
    wndclass.lpszClassName = szAppName ;

    if (!RegisterClass (&wndclass))
    {
          MessageBox (NULL, TEXT ("Error registering window!!"),
                      szAppName, MB_ICONERROR) ;
          return 0 ;
    }
   
    hwnd = CreateWindow (szAppName, TEXT ("Typing Program"),
                          WS_OVERLAPPEDWINDOW,
                          CW_USEDEFAULT, CW_USEDEFAULT,
                          CW_USEDEFAULT, CW_USEDEFAULT,
                          NULL, NULL, hInstance, NULL) ;
   
    ShowWindow (hwnd, iCmdShow) ;
    UpdateWindow (hwnd) ;
   
    while (GetMessage (&msg, NULL, 0, 0))
    {
          TranslateMessage (&msg) ;
          DispatchMessage (&msg) ;
    }
    return msg.wParam ;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    HDC            hdc ;
    TCHAR s[] = TEXT("Skies are \n blue");
    PAINTSTRUCT ps;

    switch (message)
    {
        case WM_CREATE:
          hdc = GetDC (hwnd) ;

          ReleaseDC (hwnd, hdc) ;
          return 0 ;

 

    case WM_PAINT:
        hdc = BeginPaint(hwnd,&ps);

                TextOut(hdc,0,0,s,lstrlen(s));
                EndPaint(hwnd,&ps);
                break;

        case WM_DESTROY :
        PostQuitMessage (0) ;
        return 0 ;

        default:
                DefWindowProc(hwnd, message, wParam, lParam);
        }

        return 0;
}

Good 'ole WM_NCCREATE :)
WM_NCCREATE message (Windows)

Read the "Return value" section and imagine why you might not be returning TRUE.

Can you tell me how to introduce a newline through TextOut. Am trying '\n' but it doesn't seem to be working...

There's no such thing as newlines with TextOut. You have to space things out yourself. GetTextMetrics can help.
