How to make a Frame Transparent in Windows

[riteshtechie]

I want to make a frame transparent, but not my forms only but of the whole system, for eg when I click on enable all frame and caption area must change to transparent

Is it possible in VB.NET?

you want to make every single visible window on the desktop transparent? Is that what you are asking?

it is possible, at least in win 7. but i don't know how

Here is a hint:
1. You'll need EnumWindows or GetWindow API to find all top-level windows.
2. Get style of those windows by using GetWindowLong API.
3. Set those windows transparent by using SetLayeredWindowAttributes API.

This will work on Win 2000 or higher.
Sorry, I don't have time to write code example. You can google them and you'll find examples.
