Extra processing required for RPC/Encoded TABLE-HANDLE parameters

For RPC/Encoded Web services, a TABLE-HANDLE parameter is a System.Array containing the <DataSet> System.Xml.XmlElement. Process the array as follows for:

Input — Create the System.Array with the XmlElement containing schema and data.
Output — Extract the last element of the System.Array, which is the XmlElement containing schema and data.

The following example shows the outlines of both procedures:

’This code goes after the code that creates XML document representing dynTTEl ’and before calling the method taking the TABLE-HANDLE parameter . . . ‘Create a System.Array containing dynTTEl dynTTArray = System.Array.CreateInstance(dynTTEl.GetType, 1) dynTTArray(0) = dynTTEl ‘Run DynTT.p wsObj.DynTT(dynTTArray) ' Process the output TABLE-HANDLE from DynTT.p dynTTEl = dynTTArray(dynTTArray.Length - 1) ’Continue with the rest of the code for processing the output . . .
