Hi Kristof,
This function will tell you the Window ID of a window by the name. If the
window does not exist, it will return zero (0)
'**********************************************************************************************''
Function WINGetWindowID(ByVal szWinName As String) As Integer
Dim i, nWID As Integer
OnError GoTo ErrorOccured
WINGetWindowID = 0
If szWinName = "" Then
Exit Function
End If
For i = 1 To NumWindows()
nWID = WindowID(i)
If WindowInfo(nWID, WIN_INFO_NAME) = szWinName Then
WINGetWindowID = nWID
Exit Function
End If
Next
Exit Function
'-------------------------
ErrorOccured:
Note "Oh oh, something didn't work as expected: " & lf & Error$()
End Function
But also remember that the name of your map changes everytim you add a new
layer unless you specify a title on the window

Subject: MI-L Check if map window is open
Any idea how to check if a map (identified by its name) is already open ?
In my MapBasic code I run the same "Map From" line several times. This results
in several instances of the same window. I'd like to put it in an "if ...
then", but I have no idea how to check if the map is already open.
The complex structure of the program does not allow me to use a variable that
holds info on the status of this map ("already open" or "not yet open").
