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!

Combobox using databinding?

Asked by Arka3L in Microsoft Visual Basic.Net, .NET, Visual Studio

Tags: combobox, vb.net, vb, databinding

I have a combobox that I am trying to populate with a list of people who are saved in a column in my database table. I tried fiddling with the built in datasource options you get when you first place the box and I can preview the data with the preview option but it just DOESN'T want to put the results list in my box and i'm starting to pull my hair out to say the least.

I've gone through the settings and changed every option and can still see the preview of my names. All I can say is that the Target Dataset drop down menu in the Preview Screen is greyed out and the Parameters section on the right says No parameters are defined on the selected object.

How come i can preview the darn thing but it can't populate the combobox when i run my program? What am I missing?

I also tried to code the results into the list with a data reader which worked but with the method I used it's only pasting the first name of the list in the box and not adding the rest of the names to select from. But i can understand why when you look at the code i've used:

Dim strSQL As String = "SELECT * FROM Doctors"
        Dim cmdSelect As New Data.SqlClient.SqlCommand(strSQL, dbConnection)
        Dim sqlReader As Data.SqlClient.SqlDataReader = cmdSelect.ExecuteReader()
 
        If sqlReader.HasRows Then
            sqlReader.Read()
 
            doctorSelect.Text = sqlReader("Doctor").ToString
 
        End If
