Can't I reduce the default size of Activex Control (rcBounds)

I am developing activex Control using MFC ,

When ever i use the ActiveX Control Wizard from the
File > New in VC++ , I will get default function OnDraw

void MyCtl::On Draw(CDC *pdc,const CRect &rcBounds, const CRect &rcInvalid){
default drawing code of Activex Control

}

My doubt is rcBounds has got some fixed size, and when I try to reduce I am getting drawing problems. Is there any solution to change the default size given to rcBounds


If any body can help me I would be lot thankful to them

Are you trying to change the size of the window or draw in an area smaller than the window? Ah, I think I understand. OnDraw should use the size of your client region. If you change the size of your window, or call the function using a rectangle that is the size you want you should be good to go.
