programmatically change the windows color border of windows 7

Question

using c# how do you programmatically change the windows border color when running aero on windows 7?

Answer 1

It is not possible to change the color of a window individually but you can change the color OS-wide via the resgistry. The entry should be something like this: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\Glass Colorization\Swatches in conjunction with HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM - ColorizationColor

From within your code you can only adjust the shape and the size of your Glass border but I don't think the color. In Windows Forms it is done like this and in WPF like this.

Answer 2

This isn't possible with C#/.NET. WPF/WindowsForms only allow you to change the borders on elements inside the application. Application borders are user-controlled.

Answer 3

While bitbonk and george have correctly pointed out that windows is not capable of changing the border colors for individual windows, you might look into owner-drawing the window. You may then be able to achieve what you need, however, the window will most probably not look like a "native" window anymore.
