Back to the future?

I have had to go back to an ASP app done with Visual Interdev this week. I forgot how simple VI 6 was and how much I still like it. Its good for quick in and out stuff.

I wonder if anyone has seen this problem with IE - I right click on pages and choose View Source but nothing happens.

Just wanted to get a quick post in.

Passing XML between layers

Well its raining here in Connecticut today so I'll be playing around with some ideas I've had for passing XML to and from my presentation layer and my facade layer. I got the idea from the MS CRM application. Microsoft created an MSDN site that documents the proxy layer (business facade). You can see it here Microsoft.CRM.Proxy Classes.

They publish schemas showing what elements are available for the entity. The data is published as views that the XML schema is mapped to so the UI developer doesn't have to know how the data store, in this case a SQL Server database, is designed. The proxy objects extend System.Web.Services.Protocols.SoapHttpClientProtocol so I think it is making web service calls (another area I haven't touched yet) to another DLL to do everything.

The app is available to MSDN Universal subscribers for free. I can't set it up because my server at home isn't set up with Active Directory yet. I was able to build the two databases it needs.

Has anyone tried this yet? I'm looking for some examples of best practices as well as cheers and jeers for this type of thing. XML itself is pretty simple, but then again so are a lot of things. Just about everything works, but how well is another story. I am by no means good at XML but I have to start somewhere so I'll be taking a few lumps as I learn.

Away we go!

My name is Paul Speranza and I have been programming for 15 years. I started with dBase and Clipper. Then came the beta of VB 1.0 and I never looked back. I did Java for about a year and a half when the company I was working for gave us the opportunity to learn it.

I went back to VB when my partner and I started our company, All Systems Go. My first client needed a VB/ASP app and I've been back in the Microsoft camp ever since. I've been coding in C# and ASP.Net since the final beta and I love it.

Glad to meet all of you.

Happy coding,

Paul Speranza
