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.

Using VBA to filter data

Asked by bluefeet10 in Microsoft Access Database, Access Coding/Macros

Tags: ,

Hi Everyone-
I am fairly new to developing with VBA and I am stuck on a problem. I have an Access database that current runs a screen scraping process to get data. The screens are being retired, so I need to connect to another source. The data from the new source is generated in XML.

Someone has previously written the code to get the data and I can retrieve most of the data that I need but the current screen scraping method uses a very long WHERE clause in the Access query. I am trying to figure out how to filter multiple items in the new query in VBA.

The current VBA routine only allows me to Filter on one item at a time, if I add multiple items they overwrite the previous filter.

Is there anyway to combine the multiple filters using an 'AND'? Like I said I am relatively new to this stuff and I don't know what to do to fix this.

Any help would be appreciated.
