Windows API

Hi:

I know about GetActiveWindow in the Windows API.
Unfortunately, that will only return the window handle if the active window is within the application calling GetActiveWindow.

I need to be able to get the handle to the active window if it's NOT part of my application.

Can I do that in VB?
If so, how?

Perhaps GetWindow, with the command being GW_HWNDFIRST

Code:

Const GW_HWNDFIRST = 0

Public Declare Function GetWindow _
               Lib "user32" _
               Alias "GetWindow" (ByVal hwnd As Long, _
                                  ByVal wCmd As Long) As Long

Help says, of this const:
The retrieved handle identifies the window of the same type that is highest in the Z order. If the specified window is a topmost window, the handle identifies the topmost window that is highest in the Z order. If the specified window is a top-level window, the handle identifies the top-level window that is highest in the Z order. If the specified window is a child window, the handle identifies the sibling window that is highest in the Z order.

Hey Brian,

I understand this is a very old blog but I'm stuck with the same problem and unable to get the application name of active window. Please give an example of getwindow library.

You quick response will be highly appreciated.
