I have a mixed-mode application in which I want to fire up the debugger if an error is found in the internal datastructures. Strange enough, the DebugBreak and __debugbreak functions don't seem to work as expected (the .Net framework seems to intercept the breakpoint exception, leading to all kinds of nasty side effects). The solution o...
Are Generic lists stored on the stack Or the heap? example //List of Ints List<int> myInts = new List<int>(); myInts.Add(5); myInts.Add(10); myInts.Add(20); Is myInts stored on the stack or the heap? If I add an int to the list, does boxing or unboxing occur? ...
We have an internal app(Thick Client) that relies on our central SQL server. The app is a Desktop app that allows the users to work in "Offline" mode (e.g. Outlook). What I need to accomplish is a way to accurately tell if SQL is available or not. What I have so far: I currently use the following method --> internal static void Che...
I'm looking for a regular expression library in .Net that supports lazy evaluation. Note: I'm specifically looking for lazy evaluation (i.e., the library, instead of immediately returning all matches in a document, only consumes as much of the document as necessary to determine the next match per request), NOT support for lazy quantifie...
Still new to NHibernate. I'm using NHibernate 2.1.2 and the Linq provider. I am wondering where I should put my business rule logic. For example, I have an entity called Service with DateTime property. In my web app, I only ever want to display/work with services whose DataTime is less than 4 weeks away. Where should I put that rule? I...
I have here what would appear to be a simple task; listing all the instances of a service object actively managed by a WCF ServiceHost at any particular time. For example, my service contract interface is IFooService and the implementation is FooService (with a per-session behaviour). On the service side I simply instantiate the service...

I'm trying to get a third party app (hMailServer) to consume my C# library. They support 3rd party libraries using VBScript hooks.

Is there a simple .NET code generator for a Event-driven finite state machine? I am tired of doing this by hand for user-interface objects. I just need the enum definition, the switch statement, and each function call. I do not need a "library". See Event-driven finite state machine at http://en.wikipedia.org/wiki/Event_driven_finite_s...

An example would be this: char* error = NULL; LLVMVerifyModule(PointerToSomeModule, LLVMAbortProcessAction, &error); What should I do to allow this function to be used in...

I’ve got a predefined Dataset with DataTables and DataAdapters in my applications. However, I now want to be able to modify the SP in SQL Server to add fields as needed, and have that reflected in the DataSet’s DataTable dynamically. This goes from a WebService into XML then goes to the client and gets converted back to the DataSet and...
