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!

Don't evaluate start and end time if no records are present in the form

Asked by joeserrone in Microsoft Access Database, Access Forms

Tags: Access

Hello Everyone,
I have the following code in the Form_Unload Process to check that the Start Time is > of the End Time. However I noticed that when the query running in the background of the form has no results when I close the form I get an error message " You entered an expression that has no value"
Is there a way to modify this code so that if no records are displayed on the form that when I close this code will not proceed with making sure the start time is > of the End Time

Private Sub Form_Unload(Cancel As Integer)
 
If Nz(Me.Start_Time, 0) > Nz(Me.End_Time, 0) Then
 MsgBox "Your End Time appears to be at an Earlier Time than your Start Time. Please revise your Start Time and your End Time"
          Me.Start_Time.SetFocus
          Cancel = True
   End If
End Sub
