Is this how you guys change the font face and height on a Windows program?

I've been reading Mr. Petzold's book for about two days now and I'm on chapter three where he shows us a program that will display a window with Hello, Windows 98! on its center. As this is all new to me, I thought it was pretty cool but I didn't like the font face he used at all and decided that I'd try to change it. After doing some reading on his book and also on the internet, I came up with this code and I'd like to know if this is the correct way of doing what I wanted. Thanks for your time.

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 ("Hello Word") ;
    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 ("This program requires Windows NT!"),
                      szAppName, MB_ICONERROR) ;
          return 0 ;
    }
   
    hwnd = CreateWindow (szAppName,             
                          TEXT ("Hello world 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)
{
    LOGFONT    lf ;
    static TCHAR szText[] = TEXT("Hello world!");
    HDC        hdc ;
    PAINTSTRUCT ps ;
    RECT        rect ;
   
    switch (message)
    { 
    case WM_PAINT:
          hdc = BeginPaint (hwnd, &ps) ;
       
          GetClientRect (hwnd, &rect) ;
       
          lf.lfHeight = 10;
          strcpy(lf.lfFaceName, "Courier");
       
          SelectObject(hdc, CreateFontIndirect (&lf));
          TextOut(hdc, rect.left, rect.top, szText, lstrlen(szText));
       
          DeleteObject(SelectObject(hdc, GetStockObject(SYSTEM_FONT)));
       
          EndPaint (hwnd, &ps) ;
          return 0 ;
       
    case WM_DESTROY:
          PostQuitMessage (0) ;
          return 0 ;
    }
    return DefWindowProc (hwnd, message, wParam, lParam) ;
}

I've noticed one problem: if I move the window around the screen, the letters get all scrambled up. Why is this happening? :(

Nevermind. Problem solved.
