I've been beating my head against a problem for about a week and am now resorting to just a "is it even possible question". Can other language connect to a web service that is written using .Net's WCF 4 framework? When WCF first came out years ago (under .Net v3.0/winfx), I was able to connect a Java client to it using the basicHttpBi...

I am trying to reference a class library from a Visual C# SQL CLR Database Project but I get the error A reference to 'class library' could not be added. SQL Server projects can reference only other SQL Server projects. Is there a way to add the reference so I don't need to duplicate the code in that class library? EDIT - Solutio...

I have this property, which is working fine: public IEnumerable<IGrouping<MessageType, Message>> MessageGroups { get { return (from msg in _messages orderby msg.Type descending group msg by msg.Type); } } However, it's causing me to have to repeat the ugly-looking IEnumer...
I've been checking out what is possible with the Office Open XML specification for documents. I'm particularly interested in being able to add custom XML content to a document and binding it to content controls. I was wondering if it is possible to have a repeating content control type? For example, say I have some custom XML in my .d...
I'm scratching my head on this one... I have date/time columns which I want to sort by date/time but when filtered, only filter by the date part of the date/time. My filter code (a lambda contained within a setup method) looks like this: this.taskGrid.AllowFiltering = true; this.odsGrid.Filtering += (sender, e) => ...

I installed the 32 bit file however, whenever I try to input any new connector information after the 1st keystroke the box disappears. So I'm assuming that it has more to do with my machine be...

I have seen apps implementing this interface everywhere. In many cases, we could use the new property syntax like public int Foo { get; set; } which I like very much. However, in order to implement this interface, this one has to turn into 10 lines or so. This makes the code very cluttered, and I'm not sure if it also hurts performan...
In VB.Net with Winforms how do I make an image follow the cursor even when it leaves the form? I want to do this during a drag and drop operation. BCL and/or GDI is better for my usecase than P/Invokes. If you are familiar with PeaZip, it does something of this sort when dragging a file from it's interface. ...

Does anyone know of a better custom control of a ComboBoxCheckBox than this one: http://www.codeproject.com/KB/combobox/extending_combobox.aspx? Preferabbly open source, but if not, paid. I've looked around and can't seem to find even a commercial one (then again, I don't know of that many .NET control vendors). What better? A better .D...
