login to website in script

Since search is broken, I wonder if anyone can help me with this. I have an internal website on my corporate network that I want to automate logging into and searching a specific field, extracting something from it and writing to an excel spreadsheet. It has to be in IE11. The site has a lot of Javascript behind it and I can run the debugger in it and see the code but I can't figure out the form name. I've tried it in excel VBA and powershell so far with no luck because they both need the form name to be able to post. Here is the code from the website.

Code: Select all

Since search is broken,
I don't have an answer for your question but you do know you can use Google to search the site. Most of the time that is what I use because it is better at indexing the site then using the site search. Just append this to the end of your Google Search: site:dostips.com

Yes, that is what I figured out earlier. There were only a couple of hits and they just said use telnet which you said was really stupid and I agree.
