reference to a non-shared member requries an object reference

[taersious]

Can someone tell me what is the matter with this code:

    Public Sub showdataset()
        For Each dt As DataTable In dsEvents.Tables
            Response.Write("<table border='1'>" & vbCrLf)
            For Each row As DataRow In Table.Rows
                Response.Write("<tr>" & vbCrLf)
                For Each dc As DataColumn In Table.Columns
                    Response.Write("<td>" & row(dc).ToString & "</td>" & vbCrLf)
                Next
                Response.Write("</tr>" & vbCrLf)
            Next
            Response.Write("</table>" & vbCrLf)
        Next
    End Sub

Do you maybe want dt.Rows instead?

What error are you getting, and where? Give us a clue to go on, okay?

Yes, when I changed Table.rows to dt.rows and Table.columns to dt.columns, the problem went away.

But a new problem shows up now.

    Public Sub showdataset()
        For Each dt As DataTable In dsEvents.Tables
            Response.Write("<table border='1'>" & vbCrLf)
            For Each row As DataRow In dt.Rows
                Response.Write("<tr>" & vbCrLf)
                For Each dc As DataColumn In dt.Columns
                    Response.Write("<td>" & row(dc).ToString & "</td>" & vbCrLf)
                Next
                Response.Write("</tr>" & vbCrLf)
            Next
            Response.Write("</table>" & vbCrLf)
        Next
    End Sub

I've tried passing the Dataset as a referenced argument to this Sub, but that was no help.
To be more specific, the exact error is:

System.NullReferenceException: Object reference not set to an instance of an object.

Sounds like an object isn't initialized, more specifically whatever dsEvents is. (dataTable I'm assuming)

Assuming the underline (and red) dsEvents is where the error is that you're telling us is a null reference exception, it's say dsEvents is null (equal to 'Nothing') when it hits that line. You should probably initialize it (dsEvents = New DataSet) at some point before using it. You might also want to fill it before using it too.
