SYMPTOMS
When you call an XML Web service in Microsoft Visual Studio 2005, the call fails. Additionally, the Web service returns the SOAPCLIENT_PARSE_ERROR error flag. This problem occurs if the following conditions are true:
 * The Web service returns a nested structure from an unmanaged Microsoft Foundation Classes (MFC) client application.
 * The nested structure contains an array.

Additionally, when you pass the nested structure as a parameter by reference to the Web service, the Web service cannot access the correct value.



CAUSE
This problem occurs because the CSoapSocketClientT class cannot handle a nested structure that contains an array. Additionally, the CSoapWininetClient class cannot handle a nested structure that contains an array.
