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!

Global variables in Access VBA - How?

Asked by Angelp1ay in Access Coding/Macros, Microsoft Access Database, Access Forms

Tags: access, global, vba, variable

*************
* Background *
*************

I need to store and update data in a load of global variables:
- When I load up forms I pre-populate the fields with this data.
- When controls are changed the global fields I update the globals

I have sucessfully defined my variables in a module like this:
    ' Setup globals
    Global gblUser As Integer
    Global gblSampler As Integer
    Global gblProject As Integer
    Global gblExportPath As String

*************
* The problem *
*************

When I hit an error all the globals are lost (reset to default non-initiated values - "" or null or something).

********
* Ideas *
********

- Everytime I call a global I check it's not blank - if it is I reset globals to defaults.
- Save the values of globals in a db table.
- Open a form and set controls in this form to the global values. Grab / update the data straight from here.

***************
* My question!!! *
***************

What is the best way to store "globals" in Access?

Please feel free to add your own ideas - preferably really good ones :oD
