I'm having a problem with setting up a WCF web service integration with a 3rd party. It appears that it's not correctly deserializing the response object, I'm just getting a null from the web service call. The 3rd party is using this web service framework, which has a large set of abstract and complex types for performing simple operat...

I'm in the middle of a research for defining a reporting tool and I've being studying a number of them: Active Reports is very good but expensive in comparison to DevExpress XtraReports (talking about features and support). My customer requires me to tell him about ...

Hi Fellow StackOverflowers, I am receiving a string in one of my .NET function. The string when viewed from the XML Visualizer looks like this: - <root> - <Table> <ID>ABC-123</ID> <CAT>Housekeeping</CAT> <DATE>21-JUN-2009</DATE> <REP_BY>John</REP_BY> <LOCATION>Head Office</LOCATION> </Table> - <Table> <ID>ABC-124</ID> <C...
I have a function that I want to allow to run for a given length of time and then, if it hasn't quit on it's own, abort. What is the best way to do this? The best I have thought of would be to run it in another thread, wait with a timeout for it to die and then use Thread.Abort() to kill it (this might not work if the function has the w...
So I'm designing a WCF service. I'm unexperienced with WCF, and I'm trying to decide whether it should be hosted in IIS, or a custom Windows service.. Or some other option? Things to consider: It needs to load data from a database on startup. It needs to maintain this data across requests, not load it each time. It needs to process mu...
I've noticed that some .NET structs can be compared to null. For example: TimeSpan y = new TimeSpan(); if (y == null) return; will compile just fine (the same with the Guid struct). Now I know that stucts are value type and that the code above should not compile, unless there's an overload of operator == which ta...
