Want screen capture of server desktop

I think that you can't get a printscreen on server because the server is
logged off.
You can try changing IIS service property. You can try to check Allow
Interact with desktop flag.

gr1.GetHdc() return the device context for a Windows GDI-based structure.
ASP.NET is not in a windows form!!
You can try making a simple form application that do this.
You can run this exe and then get the image...

I have a service (look like IIS) that can execute applicacation.
1 of this application is used for make graphics (Pie, etc...). The component
I use for render this must have the desktop because if not graph is blank!
I have set interact with desktop property of my service and there is not
problem!
When Application run I can see this!!!!
