GetForegroundWindow Function
Declare Function GetForegroundWindow Lib "user32.dll" () As Long

Platforms: Win 95/98, Win NT

GetForegroundWindow finds which window is currently the foreground window. The foreground window is the window, usually at the top of the Z-order, with which the user is currently working with -- i.e., the window with the focus. The function returns 0 if an error occured, or the handle of the foreground window if successful.

Example:

' Display the title bar text of the foreground window.
Dim hforewnd As Long ' receives handle of foreground window
Dim slength As Long ' length of foreground window's title bar text
Dim wintext As String ' buffer for foreground window's title bar text
Dim retval As Long ' return value

hforewnd = GetForegroundWindow() ' determine the foreground window
slength = GetWindowTextLength(hforewnd) + 1 ' length of its title bar text
wintext = Space(slength) ' make room in the buffer to receive the text
retval = GetWindowText(hforewnd, wintext, slength) ' get title bar text
wintext = Left(wintext, slength - 1) ' remove null character from end of string
Debug.Print "The window "; wintext; " is the foreground window."
