I forgot where I obtained this code so I'm unable to
acknowledge its author (my apologies to whomever)

'FindWindowLike
' - Finds the window handles of the windows matching
the specified
' parameters
'
'hwndArray()
' - An integer array used to return the window handles
'
'hWndStart
' - The handle of the window to search under.
' - The routine searches through all of this window's
children and their
' children recursively.
' - If hWndStart = 0 then the routine searches through
all windows.
'
'WindowText
' - The pattern used with the Like operator to compare
window's text.
'
'ClassName
' - The pattern used with the Like operator to compare
window's class
' name.
'
'ID
' - A child ID number used to identify a window.
' - Can be a decimal number or a hex string.
' - Prefix hex strings with "&H" or an error will occur.
' - To ignore the ID pass the Visual Basic Null
function.
'
'Returns
' - The number of windows that matched the parameters.
' - Also returns the window handles in hWndArray()

How to use (for example, Windows API) to obtain a list of
the applications which are running? (I need a list of file
names.)

Thank you very much in advance!
