Soap With Objects

[Guest Martin Dutton]

Hi,I am new to SOAP and am having some problems with some of the more complicated bits of it. I have no problem in connecting to a webservice and sending raw XML but unfortunately the webservice I am interfacing with likes objects to be populated and sent back instead. I have managed to get single record to update via the webservice but I keep getting the error: "Object reference not set to an instance of an object."The basic idea of the webservice is to send email contacts to be entered into a database.Does anybody know of any tutorials online for SOAP using objects. i.e. you get the objects out of the SOAP client and populate the data and send it back? I cannot find any decent description of this online at all.Thanks,Martin
