Hi:

I have a picturebox control, and at runtime various usercontrols are
added to it to make a diagram. As dynamically added usercontrols, they
are of type VBExtender.

Is there a way to save the diagram as a .wmf file? (The diagram might
extend beyond the confines of the actual picturebox on the screen.)

I have seen examples of how to print all the controls in a picturebox
(using the sendmessage function), but my usercontrols don't print
using this method. I'm wondering if there is something I can do so
that they are counted as being "owned" or "children" or in the
"clientarea" of the picturebox (the wparam for that sendmessage
function), and if doing so will also enable me to save the diagram as
well as print it.

*in case it makes a difference, the usercontrols themselves are
transparent and not windowless--their "appearance" is as shapes drawn
on them when they are created.

Thanks in advance for any ideas--

You may be able to modify the code at
http://www.mvps.org/vbnet/code/image...metafileps.htm to take a
snapshot of the usercontrol. This demo does the screen because
GetDesktopWindow() is p***ed as the hwnd of interest. It should work if you
instead p*** the hwnd of the usercontrol.
