CWindow::ResizeClient() Function for CWnd (or derived classes)

With this Function you can resize the window to the specified client area size of your CWnd or derived classes like the CWindow::ResizeClient() function.

Example

You have a dialog based application and the client rect of the dialog depends on the size of a bitmap.

Source Code

BOOL CYourWndOrDialog::ResizeClient (int nWidth, 
                                     int nHeight, 
                                     BOOL bRedraw)
{
 RECT rcWnd;
 GetClientRect (&rcWnd);

 if(nWidth != -1)
  rcWnd.right = nWidth;
 
 if(nHeight != -1)
  rcWnd.bottom = nHeight;

 if(!::AdjustWindowRectEx(&rcWnd, 
                          GetStyle(), 
                          (!(GetStyle() & WS_CHILD) 
 && GetMenu() != NULL)), GetExStyle()))
  return FALSE;

 UINT uFlags = SWP_NOZORDER | SWP_NOMOVE;

 if(!bRedraw)
  uFlags |= SWP_NOREDRAW;

 return SetWindowPos(NULL, 
                     0, 0, 
                     rcWnd.right - rcWnd.left, 
                     rcWnd.bottom - rcWnd.top, 
                     uFlags);
} // CYourWndOrDialog::ResizeClient
