'Ask for a Window title
Ret = InputBox("Enter the exact window title:" + Chr$(13) + Chr$(10) + "Note: must be an exact match")
'Search the window
WinWnd = FindWindow(vbNullString, Ret)
If WinWnd = 0 Then MsgBox "Couldn't find the window ...": Exit Sub
'Show the window
ShowWindow WinWnd, SW_SHOWNORMAL
'Create a buffer
lpClassName = Space(256)
'retrieve the class name
RetVal = GetClassName(WinWnd, lpClassName, 256)
'Show the classname
' MsgBox "Classname: " + Left$(lpClassName, RetVal)
'Post a message to the window to close itself
' PostMessage WinWnd, WM_CLOSE, 0&, 0&

Hello,

A simple and hopefully easy question. I want to place a button on an
Excel UserForm that causes the active PPT file to become the active
window

The PPt file is already open

What code should be in the button?

Thanks
Avi

Hi, in my opinion, create a Powerpoint object and open the relevant PPT.
Finally call the close method on the Powerpoint object. No need to use window
handles etc...
