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!

ADO, MySQL, and VB6 Record Locking

Asked by Gregg1009 in MySQL Server, Miscellaneous Programming, VB Database Programming

Tags: , , , ,

So, here's the story:

I am writting a VB6 program that accesses a MySQL server to get info and write info.  I am using ADO to make the connections.

The program gets a recordset and calls a phone number from that recordset.  If the caller answers, it sets the status of the call to accepted.  

This program works mostly fine.  The problem I need to run multiple instances of the program.  When I try that, every instance of the program tries to call the first record at the same time.  I need to find a way for the program to check if a record is already being accessed from another program.  I can lock the write function, but how do I stop it from trying to read the record as well?

I saw a stored procedure for SQL on this site, but it doesn't work (or so it seems) for MySQL.  I am open to doing it with ADO and VB6 or with MySQL stored procedures that I can access from VB6.  Any ideas are welcome.  Thanks.Start Free Trial
