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!

Application crashing in between, MFC, VC++

I have a Dialog box under the VC++ Client/Server (unmanaged code) application which contain two list box..One set of listbox1 data is filled from database and one set set of listbox2 from webservice...Both of them are called when I click on Search button after giving the necessary inputs in the dialog box ..The functions used to populate from database are below
-------------------------------
PrepareForSearch();
DoSearch();
"DisplayResult();
-----------------------------------------
after that I am calling Web service call via create thread...

The issue is if I select the data in the listbox( which is already filled by database) without waiting for 5 seconds for the Web serivce call to finish..the code just hangs..

The webservice data normally comes back in 3-4 seconds so if on that period someone clicks on listbox1..the program crashes..

what would be ideal solution in the scenario?
