Visual C# .Net 2.0 INotifyPropertyChanged Interface Implementation
Dear friends, In my current project I am using the CustomCollections with the help of BindingList<T> generic class to store the database records instead using DataSet objects as offline database identities.

Visual Studio Team System Passing Data Between Tests inside an Order Test
I have several coded web tests inside an order test. Does anyone know away to pass data from one web test to the next Specifically I have a web test that creates an object in a database. After I create this object I now want to send the object ID (just a Guid) to the next web test in the ordered test so that test can perform an operation on the object. I plan on putting this ordered test inside a load test so having a constant wont work. Also a static variable will work across one ordered test, but I have a feeling once I switch to a load test, the static variable will be global to the entire load test not just the ordered test. Any Ideas Web tests in ordered tests don't work very well sin ...Show All
Game Technologies: DirectX, XNA, XACT, etc. XNA Breakout
Hello, I have about a year of experence with C# and I have tried a simple game using XNA, I made breakout with some crappy homemade graphics Would anyone mind to look at my code and tell me what I could do better with Note: The game is not completely done yet but for the most part, it works. Code is at http://joshmackey.net/programming/XNA/XNA%20Breakout/ The mouse is how most users switch between windows. By restricting the mouse to your window you prevent this and your app would not be being very windows friendly. However if you really must do it this naive approach works ok - its not perfect and you need to make sure you only do it when the window has focus. MouseState state = Mouse .GetStat ...Show All

.NET Development Large Collection(s) of RegEx objects, is this OK?
I'm writing a small application that parses data from a server as it is received, and have around 500 regular expressions that, when matched, perform various tasks.

SQL Server What is the best most efficient performant way to do a Control break in SSIS?
I have an EDI file with Different Transaction types. I would like to read for a Header, capture some specific info on the header, and read for another specific tran type that comes after and capture additional info. I have a couple of ideas like tagging the records with a key and loading into two temp tables for matching later but that means I would have to do double processing. Maybe a conditional split for the two transaction types and then unioning them downstream, but not sure if the right records would be associated. Possibly tagging sequential key and writng to raw files and matching on the raw file keys downstream. I have a lot of ideas but I am looking for the best proven practice here so i don't spin my wheels or have to g ...Show All
.NET Development CRL First time error
Hi all, I'm a beginner in VSTS and C#. I have made a tool that uses a couple of references to external tools. When I run the tool, I often got a error message during the execution, saying : "The CRL has been unable to transition from COM context 0x19ffa0 to COM context 0x1a0110 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or..." If I close the debugger and re run the code, it works fine.
