IEC - cannot find button

[daniel_nolan]

I'm brand new to Python--and programming in general. I'm trying to use
IEC to control Internet Explorer. I've navigated to a page, and now
I'm trying to click a button. The button appears to be called 'PDF
Preview' but I honestly do not know whether that's the name or the
caption. Here is my code:

from win32com.client import Dispatch
import IEC

.
.
.


ie = IEC.IEController(window_num = 1)
ie.Navigate(URL_part_1 + x + URL_part_2)
ie.ClickButton(name='PDF Preview')

(I've also tried replacing name w/ caption but I get a similar error
message.) I get this error message:

Traceback (most recent call last):
File "C:\Program Files\Python25\experiment", line 14, in <module>
ie.ClickButton(name='PDF Preview')
File "C:\Program Files\Python25\lib\IEC.py", line 126, in
ClickButton
elem = elemcoll.item(i)
File "<COMObject <unknown>>", line 3, in item
com_error: (-2147024891, 'Access is denied.', None, None)

I really have no idea how to interpret this. I'm pasting the button
tag below:

<td>
<input type="button" value="PDF Preview"
onclick="javascripterformPdfPreview(2);"/>
</td>

You might want to look at PAMIE instead. It sounds like a Python
project that's aimed at automating Internet Explorer:
http://sourceforge.net/projects/pamie/

But if you really like COM, I found this tutorial:

I'm not very good with COM, but I would recommend that you do some
research on it. From the traceback, I would guess that you don't have
administrator privileges (of some sort) on the machine you're running
the script on.

Thanks for the input, Mike. Since I don't have much experience w/
either, I don't have a strong preference for COM over PAMIE. I'm just
frustrated my script isn't working. I guess it could have to do w/
privileges. I'm using a VPN connection. I tried turning off my
antivirus software before running the module. I can click on the
button I want manually, and get the page I need, so I wonder if I can
adjust some settings to allow Python to take control of certain
things? That or I thought it might have to do w/ a javascript error.
By looking at the tag, does 'PDF Preview' look like the name of the
button or the button caption? Let me know what you think.
