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!

ADODB Connection to a Microsoft Access DB from a VB 6 application

Asked by wilsoada in VB Database Programming

Tags: , , ,

I am trying to set up my first connection using ADO from VB6 to a Access database.

Some settings:
I have the Microsoft ActiveX Data Objects Recordset 2.7 Library and the Microsoft ActiveX Data Objects 2.7 Library references both selected in VB6 for the application

The Access database is created and closed and the table names are correct

I am trying to open a connection to the database and then retrieve a simple record from the database.

Connection:

Global Conn As New ADODB.Connection
Public Sub DBConnect()
    Dim Cmd As New ADODB.Command
    Dim RS As ADODB.Recordset
    Conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\Program Files\Microsoft Visual Studio\VB98\Database Editor\DBEditor.mdb"
    Conn.Open
   
    Cmd.CommandText = "MT"
    Cmd.CommandType = adCmdTable
    Set RS = Cmd.Execute

Error:
The above code gives me an error RunTime Error: 3709 The connection can not be used to perfrom this operation. It is either closed or invalid in this context.

So I tried a new type of query using SQL and got the same error.

Global Conn As New ADODB.Connection
Public Sub DBConnect()
    Dim Cmd As New ADODB.Command
    Dim sqlString As String
    Dim RS As ADODB.Recordset

    Conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source = C:\Program Files\Microsoft Visual Studio\VB98     \Database Editor\DBEditor.mdb"
    Conn.Open
    sqlString = "SELECT * FROM MT"
    cmd.CommandText = sqlString
    cmd.CommandType = adCmdText
    Set RS = Cmd.Execute
End Sub

I get the same error message again. I think something is wrong with my database even though it connects with no error's HEEEEEEEEEEEEEEEEEEEEEEEEEEELP!!!!!!!!!!!!!!!!!!!!!!
