Thanks Dmitry,
I tried the "set map redraw" method and that did not seem to do the trick,
let me explain my problem ...
I'm creating a map using automation through a VB DLL I have created. When I
output the map to a JPEG using the 'save window' command all the layers are
'mixed up'. By that I mean some parts of one layer are below another layer
but above it in other areas (wierd).
When I do the whole process manually from within MI the output is fine. I
figured if I could re-draw the window within my code, then it would solve
the problem, but no joy so far
I would rather avoid using API calls if I can,
Scott..

Hello Scott!
Is there a mapbasic command (or some other way in MB) to force a map
window to re-draw ?
For Map window, you can use Set Map Redraw On statement. If this is not
sufficient (as it was
in my recent case with Integrated Mapping) - use InvalidateRect and
UpdateWindow APIs:
Declare Function InvalidateRect Lib "user32" Alias "InvalidateRect" (ByVal
hwnd, ByVal lpRect, ByVal bErase As Integer) As Integer
Declare Function UpdateWindow Lib "user32" Alias "UpdateWindow" (ByVal
hwnd As Integer) As Integer
To obtain hwnd handle of the window you want to redraw - use
WindowInfo(MapInfoWindowID, WIN_INFO_WND)
In call to InvalidateRect, supply 0 for both lpRect and bErase parameters.
