What might it be...?
FindWindow is an alias of FindWindowA or FindWindowW depending if unicode/wide condition was defined prior including the headers. So: there is no FindWindow, as pointed by others on this thread.Interesting. Thanks for the help. C:\>strings \WINDOWS\system32\user32.dll | grep  FindWindow FindWindowA FindWindowExA FindWindowExW FindWindowW Any guesses as to how VB is able to accomplish its snippet? <DllImport("user32.dll", CharSet:=CharSet.Auto)> _ Public Shared Function FindWindow(ByVal lpClassName As String, ByVal lpWindowName As String) As IntPtr End Function
Magic is in CharSet... Depending in the character encoding NET is doing the magic of turning String to WideString for you, transparently.
Does it add a W or something, for us? (and ffi theoretically could, too?)
