Hi Heath, just to let you know i finally cracked it, a combination of thinking about your posts properly and spotting a very stupid mistake i was making. Thanks a lot for your replies! Paul Griffin

You can get DPI from graphic: Graphics.DpiX and Graphics.DpiY

LMAO... I hope you weren't plugging for Transcender. They have been bought out and I dance around the purchase agreement! The company has ruined my family forever! I will boycott to the bitter end! :rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes::rolleyes:

What I have found in my development is that if the application is installed locally on the user's machine, it works fine (can access the file system). It's only when they try to run the program from a network share that they get the security error. Josh Find a penny, pick it up, and all day long you'll have a back-ache...

Thanks Philip believe or not though i've just managed to get around it by trying something a little different.... instead of trying to re create the Rects after the scroll i just modified the mouse click point by subtracting the scroll offset .. that way i don't have to touch the Rects... but thanks for that info .. i'm sure i'll need it further down the road at some stage Cheers Paul Paul Griffin

Hope I have not misread what you are after, as what I think you are after is really easy On you form you have a label called lblMessage that says "hello" and a button called butChange add the method private void butChange_Click(object sender, System.EventArgs e) { lblMessage.Text = "new text" ; } hope this helps and sorry if i missed the point :beer: Reiss

Have a look at: Graphics.DrawPolygon();

Take a look at DrawCli MFC Sample.
