Nice article. However, in most cases a believe intersecting regions might be even easier. Thanks a lot!

For InstaPix; Just put a panel or something transparent in the form then have the control Dock Fill the panel.

You're making sense, but I wouldn't immediately know a solution, sorry

what about the ClientRectangle? I'd like to use a shaped form like this, but inside of it i want to be able to use the standard Dock Fill method to have a child control resize to an inset position... e.g. i want to draw my own title bar and resize edges. when i just shape the window, the ClientRectangle is always the max size, so components which Dock Fill stretch out over my edges!

Am I making sense? I tried overriding WndProc for WM_NCCALCSIZE, but even though I inset the ClientRectangle, it seems to have no effect.

Strange...
When i put your line in my project the image gets shifted higher then the region.

But when I set the FormBorderStyle to FixedSingle it works again.

It could be a version issue?

Anyway, it works for you, that's what counts :)

I used your uploaded project and it has the FormBorderStyle property already set to None.

Did you forget this step?
"Now we go to our Form, you'll have to set the FormBorderStyle property to None."

Otherwise you indeed have that shift because the caption gets drawn. Easier with a property then by code ;)

after this line:
this.Region = RegionConvert.ConvertFromTransparentBitmap(imageBackground, transparentColor);

I must add this one:

this.Region.Translate(SystemInformation.FrameBorderSize.Width - 1,SystemInformation.CaptionHeight + SystemInformation.FrameBorderSize.Height - 1 );

Dont ask me why, but it works fine now :) :)
