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!

A Threaded Question... Where's my needle.

Asked by SJohnson in Delphi Programming

Hi Folks,

I've been programming for a few years now, and I am starting to think about threads. I know I am really slow in taking this up, but up until today, I have really had no use of them, which means I haven't done much reading on them.

This question is in two parts. The first part is, can anyone tell me, if I have an app which is fairly CPU intensive (ie, losts of DB calls), can I use a thread to write back to a label with an expected completion time, and actually get that label to update - even while the main app is still churning away?

The other part is, can someone give me a simple example of how I would do this? I've played around for the last couple of days and managed to get one going (just adding the time to the caption bar of the main form), but when I start doing something intensive on the app side, the thread stops working until the app stops working.

Thanks for any help/info.

Stu.

(PS. I'll split the points in half - 150 each - for each part if answered by two seperate people)
