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.

Question about program startup and connecting to a DB

Asked by samic400 in Visual Basic Programming

I have a program that will contain one main form and many children forms attached to it. Before I even get that far as launching the forms I need to have a routine that will verify that it connect to the database. No sense of even displaying a form if I cannot get to the DB. My main form is called frmMain. Should I have a little routine in there to check and verify that I can connect to the DB. If not, show the error message and exit the form and end the program OR should I have another mechanism to check the DB connectivity. If OK, then show the main form.

I have a class module with all of my ADO calls and procedures. I'm just trying to figure out the best place to place this initially so I can make the references to all of these procedures from any form in my app, which I'll have about 20. Just trying to get this ironed out before I continue because I'll be referencing a ton of DB calls from where ever I decide to initially create the class module.

So my question is where should I place the code to access the class - in my main form frmMain or somewhere else like some sort of form that gets launched and then hidden for the remainder of the execution of the program. Just looking for the best way to do this for future projects and the reasons why or why not doing it one way or another.
