Processing the schema and data for an output TABLE-HANDLE parameter

This example shows how you might process the data from an output TABLE-HANDLE parameter by walking the output XML Schema and XML data to create a .NET DataSet and bind the DataSet to a .NET DataGrid:

Dim schemaEl As XmlElement Dim dataEl As XmlElement Dim node As XmlNode Dim type As XmlNodeType ... ' Extract the schema and data elements from the output schemaEl = Nothing dataEl = Nothing For i = 0 To dynTTEl.ChildNodes.Count - 1    node = dynTTEl.ChildNodes( i )    type = node.NodeType    If type = System.Xml.XmlNodeType.Element Then       If schemaEl Is Nothing Then          schemaEl = node       ElseIf dataEl Is Nothing Then          dataEl = node       Else          ‘Too many elements, something is wrong       End If    End If Next i ' Load schema and data into a System.Data.DataSet, then bind to a ‘ System.Windows.Forms.DataGrid mySchemaReader = New System.Xml.XmlNodeReader(schemaEl) myDataReader = New System.Xml.XmlNodeReader(dataEl) myDataSet.ReadXmlSchema(mySchemaReader) myDataSet.ReadXml(myDataReader) ' Load myDataGrid with the output from DynTT myDataGrid.SetDataBinding(myDataSet, "Item")
