Zoom

[Moonmoon]

I have a window where a bitmap is displayed. Next I have a menu "Zoom"
On selecting Zoom a dialog is displayed that has 3 radio buttons.
ist radio button shows zoomto 100%
2nd radio button shows zoomto 200%
3rd radio button shows zoomto 300%

On selecting each radio button the bitmap can be zoomedto the respective size.

I have used stretchblt() but it is not working . Please give me a detailed help.
Thanks

Hi!
I want to know what is not working.
Is StretchBlt() or ur bitmap?
Describe detail info. Sounds like
U didn't resize your bitmap area as
U are zooming.

Hi!
I forgot to ask you.

Are U sending a message or something from ur dialog
to ur window that selection of a radio button
has changed when U press a different radio button?
