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!

Events handling query

Asked by stuart_dent in Microsoft Visual Basic.Net, .NET Framework 2.x

Tags: event, handling, cancel

I currently havea form with one button. The form contains the code below. The code displays up to 5 message boxes each with OK Cancel buttons.
If the user clicks OK, the button NEXT msg is shown.
If the user clicks Cancel, then no more msgs appear.
Finally, the "The End" message is shown.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If MessageBox.Show("Blah Blah One.", "", MessageBoxButtons.OKCancel) = Windows.Forms.DialogResult.Cancel Then
        ElseIf MessageBox.Show("Blah Blah Two.", "", MessageBoxButtons.OKCancel) = Windows.Forms.DialogResult.Cancel Then
        ElseIf MessageBox.Show("Blah Blah Three.", "", MessageBoxButtons.OKCancel) = Windows.Forms.DialogResult.Cancel Then
        ElseIf MessageBox.Show("Blah Blah Four.", "", MessageBoxButtons.OKCancel) = Windows.Forms.DialogResult.Cancel Then
        End If
        MessageBox.Show("The End")
End Sub

The code is not easy to read.understand. Each line has too much code related to the result of the messagebox.

I would prefer to have something like the following:
        MessageBox.Show("Blah Blah One. ")
        MessageBox.Show("Blah Blah Two. ")
        MessageBox.Show("Blah Blah Three. ")
        MessageBox.Show("Blah Blah Four. ")
        MessageBox.Show("Blah Blah Five. ")

        ' if any of the MessageBoxes above ever returns DialogResult.Cancel
        ' then jump to this spot.
        MessageBox.Show("The End")

Is there a way to do this???

Thanks
Stu
