Hi all...
I'm trying to retrieve a SQLXML query using VB.NET. When I programmed in VB
6.0, I used Stream object to accomplish this which was trivial.
I cannot do the same thing in VB.NET. Here the most similar object is the
OleDbDataReader. I have the following method, ¿is it correct what I am
doing? By doing oRdr.GetBytes(0, 0, bBytes, 0, 1000) I'm limiting only to
1000 bytes. How can I know the length of the stream?
Public Function get_Tree(Optional ByVal sEstado As String = "") As String
Dim oConn As New OleDbConnection(m_sConn)
oConn.Open()
Dim oCmd As New OleDbCommand("SP_GET_CATEGORY_TREE", oConn)
Dim oParamEst As OleDbParameter = New OleDbParameter("@CAT_EST",
OleDbType.VarChar, Len(sEstado))
oParamEst.Value = sEstado
oCmd.Parameters.Add(oParamEst)
oCmd.CommandType = CommandType.StoredProcedure
Dim oRdr As OleDbDataReader = oCmd.ExecuteReader
If oRdr.Read Then
Dim bBytes(1000) As Byte
oRdr.GetBytes(0, 0, bBytes, 0, 1000)
Return "" ' I NEED TO RETURN THE XML THAT IS RETURNED FROM
THE SQL SP (AS FOR XML AUTO)
End If
End Function
Any help will be greately appreciated,
Jaime
