I have a property on a label bound to a Setting in my App Setting file. What I am wondering, Can I hook a OnPropertyChanged() up to this some how? I know there are other ways I may accomplish this but this got my curiosity up so I thought I'd ask. EDIT The reason I am asking is when the bound property of my label - Tag(bool) chan...

For WCF I need to specify that the known type for any IEnumerable<T> is T[]. Is there any way that this is possible using the configuration section? Something like the following, though I know it doesn't work just like this: <system.runtime.serialization> <dataContractSerializer> <declaredTypes> <add type="System.IEn...
I have an application consisting of several WCF services, some of which are implemented in Workflow Foundation (.NET 3.5), others just plain C#. These services communicate with each other over a netNamedPipeBinding for performance reasons. The trouble is that I'm seeing more and more CommunicationExceptions and underlying PipeExceptions ...

I've implemented a customized QueryStringConverter class and hooked it up using a customized WebHttpBehavior subclass. When I make a service call, it hits my breakpoint in the CanConvert override (and I return true for this parameter), but it never calls my ConvertStringToValue override, and ends up just passing null to the service call....

I've been trying to get this to work for weeks now, all to no avail. I am sure that my code must be failing through something fairly small and stupid, but having tried a number of different approaches I'm starting to really struggle as to what the problem might be. Has anybody else managed to get the jQuery Week Calendar (http://github.c...
Update: False alarm! The source of the error was elsewhere. (See at the end of the question.) Is it possible that either Linq or foreach can mess up the order of an array? One of my testers reported to have experienced that the order of a list of items he fed in as input didn't match the order of the final list that was saved in the da...
I have a LINQ expression that's slowing down my application. I'm drawing a control, but to do this, I need to know the max width of the text that will appear in my column. The way I'm doing that is this: return Items.Max(w => TextRenderer.MeasureText((w.RenatlUnit == null)? "" : w.RenatlUnit.UnitNumber, this.Font).Width) + 2; Howeve...
We use absolut path or relatvie path to find a file in our C# application right now. Is there a way to find the file just by its name if the file is under the currect working directory or under one of the "paths"? Use absolute pathe is not good and use relative path is not good enough because we may change project structure by rename o...

We are currently designing a solution that will run as a .Net Web application behind a WebSeal reverse proxy. I have seen some comments on the net where people have had various problems with this, for example rewriting of viewstate.

I have a potential project where I would be working on developing the "Data Access Layer" of a reporting application using ADO.Net and LINQToSQL. I have not specifically worked on a Data Access Layer project (middle tier), so I was wondering if anyone here could provide a sample / example / resource, where I can get an idea of what th...
I'm working on a WinForms C# 3.0 / .NET 3.5 project involving building some canned reports. One of the requirements of the project is to export to PDF format, and currently doing so to disk is working just fine.
