  : Hi, all:
  : I have a question about using a hook in my program. As is known that we can use a function SetWindowsHookEx(...) in Win32API and C/C++ programming. Now I want do it with BCL and C# in Windows Form progamming. For example, I want to get keyboard message when the form is mininized or unactived. How can I do?
  : Thanks for any advices.
  :
  In vb.net you use the same old declare statement from vb6. In c# you will use a statement like the following...
  [code]
  using System.Runtime.InteropServices
  
  [DllImport("kernel32")]
  private static extern int Beep(int dwFreq, int dwDuration);
  [/code]
  
  This is a sample that I saw in a book, but all you have to do is modify the func name and the parameters. (I think) If not, it'll be close enough that you could wing it.
