How can I add a XML prefix to fields in WCF Message Serialization? I'm connecting up to a Java Spring web service from .NET, and an object that I pass in with parameters is being serialized as you would expect: <MyClass> <field1>Field 1 Value</field1> <field2>Field 2 Value</field2> </MyClass> However, the web service requires tha...
Hello, I have one dataset with a few tables. In one of the tables where I'm adding to, I would like to have a constraint where it will only allow to add a row if I have a unique value in a column. Table: Users Columns: AutoID, GroupID, UnitID*, etc. In the MVS2008, I went to the Designer and set the Unique property for UnitID to true...
I have an application with several windows where only the main window appears in the taskbar. With a click on the icon in the taskbar I want all my application windows to show up on top of any other open windows.

After reading "Odd query expressions" by Jon Skeet, I tried the code below. I expected the LINQ query at the end to translate to int query = proxy.Where(x => x).Select(x => x); which does not compile because Where returns an int. The code compiled and prints "Where(x => x)" to the screen and query is set to 2. Select is never called, bu...
Hi, I can't seem to figure out captures + groups in Regex (.net). Let's say I have the following input string, where each letter is actually a placeholder for more complex regex expression (so simple character exclusion won't work): CBDAEDBCEFBCD Or, more generically, here is a string pattern written in 'regex': (C|B|D)*A(E*)(D|B|C...

I configured it to use the XmlSerializer rather than its default DataContractSerializer, for greater control over the XML format. I created a generic ResponseContract<TResponse, TErrorCode> data contract, which wraps the response with <Api> and <Response> f...
Several weeks ago, my company laptop started having some strange problems. I could no longer launch the Microsoft Developer Web Server (via Visual Studio->Debug). I later figured out that I couldn't execute any .NET application. In speaking with Microsoft CLR specialist after reviewing my dmp files, he said When loaded into yo...
I committed a project to VSTF and then pulled it down locally on another machine. It works fine on my dev box, but on the other machine, the WCF RIA Service link appears to be gone and there is no option to re-add it in the project properties. See image for clarification: http://imgur.com/XIwfB.png What's missing on the other machine? ...

Apparently the code generator for the designer class, EntityModelCodeGenerator that is, uses the "Entity Container Name", a property of the model, for the name of the connectionstring; meaning that the model constructor in the designer class that has the named connection string parameter will always be generated using the Entity Containe...

Maybe, i'm duplicating some existing theme (close this one if it's true) but i'm planning to work with high load web services and curios about best practices. I have projects on Java and Grails. I'm doubt if Grails is right solution for high load service but Java (without any Hibernate or similar tools) can be used very well. Anyway, w...
My one ASP.NET web site uses two different business object class libraries. There is a common framework DLL (CSLA.dll) between these two libraries. The problem is that one library wants to upgrade to CSLA v.4.0.1 and the other wants to remain at v.2.1.4. How do I solve this conflict at the web site? I think I need to install both versio...
I have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting. I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NE...

This works fine and when everything loads the arrow is moving along the path fine... But when the user clicks a button - in the button handler I need to change the...
Hi, we have performance issues in one of our WCF web services. We experience that: ASP.NET runs out of worker threads and starts queuing. No magic. WCF queues work items to be processed by an IO threads. Ok. I understand that delays can occur while new IO threads are being created. Those delays can be substantial. However, it seems...
