Conversion problem

Public Sub GetPathway(ByVal vABR_ID$)
        If SqlConnection1.State = ConnectionState.Closed Then
            SqlConnection1.Open()
        End If
        Dim DsPathway1 As String
        SqlDiplomateAdapter.SelectCommand.Parameters("@abr_id").Value = vABR_ID
        SqlDiplomateAdapter.Fill(DsPathway1)

The above code is an attempt to populate th a dataset.

However, the dataset includes to fields one is nvarchar and the other is a bit.  I'm getting an error say that  "As Interger  Value of type "string cannot be converted to System.Data.DataSet"
and
"As Interger  Value of type "string cannot be converted to System.Data.Datatable"

can I assume that that's because of the BIT?  What options do I have?

Regards

Dim DsPathway1 as string...

Did you mean to dim this as a dataset?

DsPathway1 is a dataset already created from a DataAdapter

The first error probably relates, with its reference to DataSet, to this line

        Dim DsPathway1 As String

As you say, "DsPathway1 is a dataset ...".  You therefore cannot Dim it here As String (or if you do, you will have problems).

The second error probably relates, with its reference to DataTable, to this line

        SqlDiplomateAdapter.Fill(DsPathway1)

DataAdapters fill DataTables, not DataSets.  True, you can call .Fill(dataset) but that will just create a new table within the dataset that it can fill.  I anticipate - from what you say about the dataset being "... already created from a DataAdapter" - that you selected the "Generate Dataset ..." option when you were configuring the dataadapter and, if that is the case, there will be a specific datatable within the dataset that you probably need to specify in the call to the .Fill method.  So I think that line should probably be something like

        SqlDiplomateAdapter.Fill(DsPathway1, "MyTableName")

A couple of other points.  One is that, with dataadapters, you don't need explicitly to open their connections: they handle that automatically.  So these lines

        If SqlConnection1.State = ConnectionState.Closed Then
            SqlConnection1.Open()
        End If

are unnecessary.

And (although perhaps it doesn't matter in practice, I'm not sure) the argument that you pass to your sub is vABR_ID$, but the Value that you give to your parameter is vABR_ID.

What I think your sub ought to look like is this

Public Sub GetPathway(ByVal vABR_ID$)
        SqlDiplomateAdapter.SelectCommand.Parameters("@abr_id").Value = vABR_ID$
        SqlDiplomateAdapter.Fill(DsPathway1, "MyTableName") '<<< you put the right value in here

The Bit field shouldn't cause a problem but, even if it does, I don't thnk you've reached that problem yet ;-)
