in an ideal world I would use remoting, but unfortunately the compact framework does not support remoting, so I am stuck with web services. Ive managed to get it to work, although I have had to implement the same thing using arrays. I could always use a web service which uses remoting to communicate with my server but I do not wish to enforce IIS be running and a web service installed.
There is an article on MSDN which is doing a similar thing to what I am doing using the same approach. Pure coincidence! http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dncodef un/html/code4fun06272003.asp thanks simon -----Original Message----- From: Moderated discussion of advanced .NET topics.

My point was that the add web reference wizard is not intended to be used with remoting endpoints. So any success you have with it is just a case of you getting lucky. And by extension, and problems you have when you attempt to use the tool in a manner it's not designed to support, you're going to be on your own. > As for SoapSuds.exe, I have no idea > what that is so ill do some reading :) > > Oh, on a side note.

You can use it from the command line as well. It's a program that's designed to take either a dll name or endpoint url as input *that refers to an xml web service* and produce client-side proxying code and/or wsdl as output. Think of the add web reference wizard as just being a fancy way to run wsdl.exe w/o using the command line yourself. Soapsuds.exe is the counterpart to wsdl.exe for the remoting world. It takes an assembly name or endpoint url as input and also generates client-side proxying code as output; but it assumes it's talking to a remoting endpoint. The 10k summary is that xml web services and remoting take different approaches to soap (document/literal for web services, rpc/encoded for remoting) and which type system governs their operations & parameters (xml schema for web services, clr type system for remoting). Each client-side tool (wsdl.exe and soapsuds.exe) are then built to recognizing & deal with the types of wsdl being returned by their corresponding servers. So when you point wsdl.exe (add web reference) to a remoting endpoint, things don't work very well due to the giant mismatched understanding each side is operating on (wsdl.exe thinks its talking to a document/literal, schema driven web service, but in fact is talking to an rpc/encoded, clr type system driven remoting endpoint). And it just won't work for anything other than the most trivial (i.e., useless) scenario. You can do what you want with remoting, there's just no wizard you can use in VS.NET to get the job done. Start with reading up on soapsuds.exe, but there are a number of other approaches possible as well when it comes to generating client-side metadata. A book like "Advanced .NET Remoting" by Ingo Rammer would enumerate those approaches for you. -Mike DevelopMentor http://staff.develop.com/woodring
