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!

Check if variable has been declared in ASP

Asked by higgsy in Active Server Pages (ASP)

Tags: variable, been, has, asp

Hi,

Im writing a script and i want to check whether a variable has been declared or not. My database connection name is objConn, and so i want to check whether that variable has been declared, if it hasnt the user is on a page that has no database driven content and so i dont want to query the DB...

I use IsObject(objConn) to check whether the variable is an object but because i have option explicit on every page that returns an error...

I could turn on On Error Resume Next before the IsObject statement but i dont like to do this because i will never know if theres an error.

Any ideas or solutions anyone....

Thanks in advance
