Hi Robert,

First issue is on a Windows 7 64bit host. I get an error trying to get
a screenshot with takeScreenShotSlow:
com_error: (-2147352567, 'Exception occurred.', (0, u'Display',
u'Argument aScreenData is NULL', None, 0, -2147024809),None)
Which before in the vbox-dev archives was established as a problem
with the COM parameters. I didn't see how it was resolved, but I
believe the suggestion was to recompile the IDL.
In upcoming versions of API screenshotting is being reworked
significantly. I will check situation with
screenshots on my Vista box, but it would be truly helpful if you send
fragments of code leading to this particular error.
Second issue is for the Ubuntu 9.10 64bit host. I can successfully get
the screenshot. But I can't control the mouse or keyboard through the
Python API: putMouseEventAbsolute and putScancode. There isn't any
error, but the code that works on the Windows host fails to give any
response on the Linux host.
This is pretty unlikely, as frontends use same API to inject user
keypresses, so if you can type in your guests, API shall work too.
Note that putMouseEventAbsolute() needs absolute pointing device, and
for scancodes injection check typeGuestCmd() in
http://www.virtualbox.org/browser/trunk/src/VBox/Frontends/VBoxShell/vboxshell.py
this one known to work pretty well. One issue you may get, is just a
timing between keypresses.
Thanks,
Nikolay
