Hi,

Thanks for looking in to this !

I have my paint function,In Which I am calling Draw Method of Objects

OnPaint(CDC *pDC)
{

For(int i=0;i<Count;i++)
{
  CShape *temp=GetShape(i);
  temp->Draw(pDC);
}

}

and
CShape as well as Derived classes implemented Draw() method.

CMyRect::Draw(CDC *pDC)
{
  //Some Code
  //
  pDC->Rectangle(...);

}

CMyDate::Draw(CDC *pDC)
{
  //Some Code
  pDC->.......

}

I want to ignore the draw code if it does'nt lies in invalidate region.

CMyDate::Draw(CDC *pDC)
{
  if(InvalidateRgn Overlaps this object Rect)
 {
   //Some Code
  pDC->.......
 }
 else
 {
    //Ignore 
 }
}

How to do this ? Is there any API for getting invalidate region.
How to get Update Rect Inside Paint() ? as its get cleared after beginpaint call !
Thanks !
