returning select value using Visual Basic 2010 oleDB - vb.net

Question

I'm trying to read a excel cell with visual basic 2010 ( I'm really new to this) and I think I finally did it BUT I have no clue how to return the result.
It should end up in the clipboard or msgBox from there I'll find my way :D
I searched for two hours now but didnt find the solution... please help me
Thanks
Private Sub Button13_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
cn.ConnectionString = "provider=microsoft.jet.oledb.4.0;data source=C:\Users\marcelf\Documents\Visual Studio 2010\Projects\WindowsApplication1\WindowsApplication1\bin\Debug\DB.xls;extended properties=excel 8.0;"
cn.Open()
With cm
.Connection = cn
.CommandText = "SELECT * FROM [ccs$C1:B20] WHERE 'id' = 'German'"
.ExecuteNonQuery()
End With
cn.Close()
MsgBox(????)
End Sub
EDIT: her is the updated code. I get "Could not find installable ISAM
Private Sub Button13_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
Dim con As New OleDbConnection
Try
Using con
'added HDR=No to the extended properties of the connection string
con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;data source=C:\Users\marcelf\Documents\Visual Studio 2010\Projects\WindowsApplication1\WindowsApplicat'ion1\bin\Debug\DB.xls;extended properties=excel 12.0;HDR=Yes"
con.Open()
Using cmd = New OleDbCommand
cmd.Connection = con
cmd.CommandText = "SELECT * FROM [ccs$C1:C20] WHERE 'id' = 'German'"
Using oRDR As OleDbDataReader = cmd.ExecuteReader
While (oRDR.Read)
MsgBox(oRDR.GetValue(0)) 'gets the first returned column
End While
End Using
con.Close()
End Using
End Using
Catch ex As Exception
Throw New Exception(ex.Message)
Finally
con.Close()
End Try
End Sub
EDIT: That's what worked for me:
Private Sub Button13_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
Dim con As New OleDbConnection
Try
Using con
'added HDR=No to the extended properties of the connection string
con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\marcelf\Documents\Visual Studio 2010\Projects\WindowsApplication1\WindowsApplication1\bin\Debug\DB.xls;Mode=3;User ID=Admin;Password=;Extended Properties=Excel 8.0"
con.Open()
Using cmd = New OleDbCommand
cmd.Connection = con
cmd.CommandText = "SELECT Service FROM [ccs$] WHERE id='" & ComboBox1.SelectedItem & "'"
Using oRDR As OleDbDataReader = cmd.ExecuteReader
While (oRDR.Read)
MsgBox(oRDR.GetValue(0)) 'gets the first returned column
End While
End Using
con.Close()
End Using
End Using
Catch ex As Exception
Throw New Exception(ex.Message)
Finally
con.Close()
End Try
End Sub

Welcome to SO. In the future you should show us all of your code. Since you tagged OleDB and vb.net, the following implements what you are trying to accomplish. I included the Form Class so the Imports statements could be shown, but you can just copy and paste the click event code after insuring you Class includes the Imports. Note, I have not tested this code but it should work. Let me know if you need clarification or additional help.
Imports System.Data.OleDb
Public Class Form1
Private Sub Button13_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
Dim con As New OleDbConnection
Try
Using con
'added HDR=No to the extended properties of the connection string
' **EDIT**
con.ConnectionString = "Provider=Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\marcelf\Documents\Visual Studio 2010\Projects\WindowsApplication1\WindowsApplicat'ion1\bin\Debug\DB.xls;Mode=3;User ID=Admin;Password=;Extended Properties=Excel 8.0"
con.Open()
Using cmd = New OleDbCommand
cmd.Connection = con
cmd.CommandText = "SELECT * FROM [ccs$C1:B20] WHERE 'id' = 'German'"
Using oRDR As OleDbDataReader = cmd.ExecuteReader
While (oRDR.Read)
MsgBox(oRDR.GetValue(0)) 'gets the first returned column
End While
End Using
con.Close()
End Using
End Using
Catch ex As Exception
Throw New Exception(ex.Message)
Finally
con.Close()
End Try
End Sub
End Class
