What is the error you are getting?

You could do a test for the number of records and only loop if it is greater than 0.

And how are you looping through the table?

Pseudo-Code:

Hope this helps

Dim myConnStr As String = "Provider=Microsoft.jet.OLEDB.4.0;Data Source=" + myPath
Dim myConn As New OleDb.OleDbConnection(myConnStr)
Dim myAdapt As New OleDb.OleDbDataAdapter(myQuery, myConn)

Try
myConn.Open()
Dim myReader As New DataSet
myAdapt.Fill(myReader)

**
** I need to check if myReader is empty
**

tbGATE.Text = myReader.Rows(0)("dGate")
tbCONC.Text = myReader.Rows(0)("dConc")
tbPAY.Text = myReader.Rows(0)("dPayment")

**
** I need to check if myReader.Rows(0)("dWeather") is empty
**

cbWEATHER.DisplayMember = myReader.Rows(0)("dWeather")

myConn.Close()

Catch ex As Exception
MessageBox.Show(ex.Message)
End Try

(For sake of confusion, I would not name my Dataset as myReader - seems to refer to a datareader to someone not knowing what you are coding for.... just some programming edicate I thought I should pass on)

Saying that......

Add the line

If myReader.Tables("dWeather").Rows.Count > 0 Then

Hope this helps

Also might do well to ensure the object itself is not Nothing.
If a SQL call fails, the dataset/table object can remain uninitialized, in which case myReader.Rows will throw an error.

ds.tables(0).rows.count

Really Janet.... A Thread From 2005?

Better late than never

Try this

If Not dataset1 Is Nothing Then
.....
... Process dataset
.....
End If

You probably can guess this from the previous threads but I use:
