When coding my user interfaces with Java we can count with the TableModel interface wich makes the process of representing objects in data tables something really easy.

We have nested stuctures as such, used as an interface for some device drivers. On occasion we have to update individual elements. An 'address of' operator would be helpful, but an 'offset' function or operator is what I'm really looking for, but not sure how to go about it. In other words, how far is structureN.elementX away from the st...
I'm working on a project where a large number of clients will be connecting to a WCF web service. When they connect, the web service will sleep until an event occurs on another WCF service running on a different server. I want the other service to "wake up" the client service when the event occurs using another WCF service call on the ba...

The first time I saw the yield keyword in C# I thought "yuck what a way to junk up the language". Having grown since then and actually used the language I find it so pleasantly simple to express state logic that I'd like to use a similar approach in other development platforms. I'm exploring Objective-C for some support utilities. Is ...
I am looking for some library that takes the TextWriter approach to writing SQL commands (much like there is the HtmlTextWriter in .Net for writing html). I am NOT writing CRUD-type commands for relational data, I am writing arbitrary SQL (bulk inserts, table creation, creating backups, etc). Any suggestions are appreciated. ...

A. ...

I'm trying to place custom objects into a sorted dictionary... I am then trying to use an extension method (Max()) on this sorted dictionary. However, I'm getting the exception: "At least one object must implement IComparable". I don't understand why I'm getting that, as my custom object obviously implements IComparable. Here is my c...

.net System.Net.Mail does not issue SMTP quit commands in version 3.5 or lower. Although the problem is fixed in .net v4.0 RTM, unfortunately v4.0 cannot handle attachments in an email larger than 3-4MB's so I can't use it in my solution. I was thinking of maybe rolling back to the now outdated CDonts found in System.Web.Mail. Can anyo...
