Actually, I am using COM to control Adobe Acrobat 7. I searched high and low
for methods to enable pdfs for commenting in Adobe Reader, and the only
method I could find was to execute the appropriate menu item in Acrobat. I
did all this in COM. The problem is that once that option is executed, the
Save As dialog pops up. Now, I am able to click the Save button (as
mentioned in my previous mail).

Between yesterday and now, I have got this:

gui.PostMessage(combo_hwnd,con.WM_SETFOCUS,0,0)
gui.SendMessage(combo_hwnd,con.WM_SETTEXT,0,'F:\Sample File.pdf' )

I am now able to set the text in the combo box. How ever this requires the
handle of the combo box. I can obtained the handles to the owner of Save As
and Save As itself.

w_hwnd=1573334
>>> gui.GetWindowText(w_hwnd)
'Save As'
>>> child=gui.GetWindow(w_hwnd, con.GW_CHILD)
>>>
>>> for i in range (20):
           child=gui.GetWindow(child, con.GW_HWNDNEXT)
           print b,'=',gui.GetWindowText(child)

3342844 =
459416 =
2031970 =
655960 =
917912 =
1114744 =
1573478 = File &name:
1442168 =                             #### this is the  handle of the combo
box
787024 = Save as &type:
852368 =
1114516 = Open as &read-only
1049194 = &Save
1900908 = Cancel
1442464 = &Help
1180026 =
1442306 =
0 =
Traceback (most recent call last):
  File "<pyshell#114>", line 2, in <module>
    child=gui.GetWindow(child, con.GW_HWNDNEXT)
error: (1400, 'GetWindow', 'Invalid window handle.')
>>>

I feel this is not the correct way to get the handle of the combo. Any
ideas?
The WM_COMMAND is sent to the Save As window with control ID = 1
(Referencing the Save button). Is there any way I can modify the filename by
sending messages to the Save As window using the control ID of the combo as
a parameter?


Thanks for taking the trouble to read!
