Find absolute screen coordinates of ActiveView

[OlaRennemo]

Hi all, I cant find the absolute screen coordinates of IMxDocument.ActiveView upper left corner.
Using dotnet:
If I try to obtain position via component reference:  "System.Windows.Forms.Control.FromHandle(new IntPtr(ActiveView.ScreenDisplay.hWnd))" I get NULL.
I have a feeling this should be very simple, but maybe its not..
Thanks for any help!

I forgot to mention: This is an ArcMap extension with a toolbar.

Would this work?

try:

My.ArcMap.Document.ActiveView.Extent.XMin
My.ArcMap.Document.ActiveView.Extent.YMax

Not quite.
Mouse positions are not availible at the time I need them.

try:

My.ArcMap.Document.ActiveView.Extent.XMin
My.ArcMap.Document.ActiveView.Extent.YMax

This gives me real world coordinates, not screen coordinates.
I can convert them the to screen coordinates, but they are always relative to the upper left corner of the map. So I need the map position as well...

i think i am not understanding what you are trying to do but; those coordinates should be the upper left corner of the map...

Have you tried using the display transformation object?  It's available through IScreenDisplay.DisplayTransformation.  It may give you what you're looking for.

I get map coordinates rater than screen coordinates... but I can convert them with IDisplayTransformation.  But as I said, point(0,0) is upper left corner of the map window, not the screen.

I am making a ArcMap extension/toolbar. Maybe the results is different if called from a standalone application ?

Thansk for your effort anyway!
