I realized I was using the position of the window within the parent window to
specify my drawing.  I have now corrected it to this:

LRESULT CALLBACK new_window_proc(HWND hwnd,UINT uMsg,WPARAM wParam,LPARAM
lParam)
{
     char *second_line = "Second line of error";
     RECT rect;
     HDC hdc;
     HFONT fnt,old_fnt;
     int diff;

     if(uMsg == WM_PAINT)
     {
          CallWindowProc(old_window_proc,hwnd,uMsg,wParam,lParam);
          hdc = GetDC(hwnd);

          GetWindowRect(hwnd,&rect);
          diff = rect.bottom - rect.top;
          rect.top = diff/2;
          rect.bottom = diff + 1;
          rect.left = 0;
          rect.right = rect.right - rect.left + 1;
          SetBkMode(hdc, TRANSPARENT);
          fnt = GetStockObject(SYSTEM_FONT);
          old_fnt = SelectObject(hdc,fnt);
          DrawText(hdc,second_line,strlen(second_line),&rect,
                   DT_SINGLELINE | DT_BOTTOM | DT_INTERNAL);
          SelectObject(hdc,old_fnt);

          ReleaseDC(hwnd,hdc);
          SetWindowLong(hwnd,GWL_WNDPROC,(LONG)old_window_proc);
          return(0);
     }

     return(CallWindowProc(old_window_proc,hwnd,uMsg,wParam,lParam));
}

The second line is displayed but with a much larger font.  How do I use the same
size font as the MessageBox font?
