Handle of a window?

Anyone knows how to find out the name of the handles of different windows in different programs?
is there any special program to do that (like i click onto window and it tells me it's handle name?) Or maybe some other way?
Please help

Thank You

Visual Studio 6 comes with a tool called Spy++ that lets you get information about a window by dragging and dropping a spy symbol onto a window.

It then displays all available information about the window.

You can use the EnumWindows API call or FindWindow to do that yourself.

Thank You!!
