The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

"Download file" dialog automation

Asked by Pakhu in Automation, Microsoft Excel Spreadsheet Software, Visual Basic Programming, VB Controls

Tags: ie, automation, vb, vba, user32

I'm trying to automate a File download dialog from a web site, using IE automation on VBA.

So far I've succeeded in getting the handle on the dialog window and the control (save button). But i can't click on it, although I've tried (as you can see in the code) several alternatives. The only thing I've get is that the focus shifts from the Cancel to the Save button, but is not properly clicked so I don't get the save as dialog as i get doing manually.

I guess I'm missing something gross here or else I'm being blocked by some kind of security settings (I'm using Vista and IE8)

Thankyou
