如何使用Global Hook

Question

I tried using global hook, and when I typed in using gma.System.Windows; it did not recognize gma? What do I need to do?

Answer 1

It looks like you may be using code from this CodeProject article . You need to reference the assembly / source code from that article. Also, you need to type Gma. rather than gma. -- C# is case sensitive.

Answer 2

If you want to stay inside the C# world, you are restricted to low-level hooks only. There is some code here and here .
