This question is about using the MFC.

CMainWnd::CMainWnd(){
  Create(NULL, "XX", WS_OVERLAPPEDWENDOW, DefauldRect,NULL,NULL);
}
void CMainWnd::OnPaint()  {
  CPaintDC dc(this);
  dc.Rectangle(100,100,180,140);
}

The above program works just fine - then when I 
try to move the "Rectangle" statement to a function I cannot
get the function to recognize "CPaintDC" ie.:


CMainWnd::CMainWnd(){
  Create(NULL, "XX", WS_OVERLAPPEDWENDOW, DefauldRect,NULL,NULL);
}
void myRect(int x) {
   dc.Rectangle(x,x,x+80,x+40);
   return(0);
}
void CMainWnd::OnPaint()  {
  CPaintDC dc(this);
  myRect(100);
}

First I tryed declaring CPaintDC dc(this) outside of both functions
(making it global), but the compiler complains about this.
If you know how to do this, then please send me some advice.
Thanks
