I had been struggling to get some of the "server"-side filtering working with the Peachtree SDK (assembly version is 17.0.0.0), and having to debug to try each combination of values of filters was annoying me, so I wrote a program using reflection to test them all. I tried to post the output here (well-formatted!), but markdown basicall...
Is there a known reason why FormatException does not inherit from ArgumentException? An invalid format would seem to be a very specific case of an argument being invalid, similar to ArgumentOutOfRangeException. The MSDN article for the class states: FormatException is thrown when the format of an argument in a method invocation doe...

Is there a length where I'll run into difficulties writing and reading a big string in one go? Right now the size of the strings I'm storing are about 100 characters but they can get into the 10,000+ range - will that be a p...
I am not sure if there is any interface already exist in .Net like this: public interface IController { T GetInstance<T>(string name) where T: class; } Basically, this interface contains a method to get instance of T by name/key. IControler is an arbitrator name I use here. It may be something like IFactory, ICreator, or somethi...

I have written a .NET C# application and have created an installer in Visual Studio 2008. Everything works fine. The application uses an external config file (not app.config). The application is written such that when the config file is deleted, the defaults for the application are restored and a new config file is created. This beha...

Note that this is tight and highly optimized code so please no cries of 'premature optimization'! Assuming scenarios where CPU and RAM are being squeezed to the limit I was wanting...
Do the .NET libraries have an easy way of returning the week number for a given date? For example, input of Year = 2010, Month = 1, Day = 25, should output 5 for the week number. Closest I found was Calendar.GetWeekOfYear, which is almost there. Java has a date string format "W" which returns week in month but I can't see anything equi...

You can assume that the transaction is active before the threads are created and that it's committed after they complete. I'm also using a TransactionScope under the System.Transactions nam...
