I'm creating a system that takes readings from a hardware device that sends data via a serial port. Every time a "packet" comes in off the serial port, I update and redraw some GUI components to reflect the updated information. Since serial port events stem from a separate thread, I have to call Invoke(Invalidate) on several components t...
I'm working with an inherited code base which contains thousands of lines of commented out code. I know the previous coder meant to save all his hard work for posterity rather than simply deleting it but: I will never read it and it just gets in the way.

I have a .NET assembly DLL that is created on-the-fly from pre-compiled code in a database. Is there a way to create the DLL file, put data into it, load it with the Assembly class, then when the process exits, have that DLL be deleted? My first thoughts were to open it with the FILE_SHARE_DELETE flag, load it with Assembly.LoadFrom, an...

At the same time we wish to be able to test that Monster - GUI automation in a maintainable way. Some challenges: The application is massive. I...

Let's say I need to use Python and C++. I can call Python function from C++ with Python C API, and reverse is possible with SWIG or equivalent. How about .NET? I know there are IronPython and C# that finally produces .NET assembly. Is there any well-defined language interoperability mechanism in .NET so that one can use whatever functi...

However i have a lot of classes that look like this public class register_email_job { public PK id; public user_data user; } public class user_comment : BaseComment2 { [IsNullable] public user_...
I am a big fan of optional parameters in C#4 but am having an issue with MVC when I use them in my controller constructors. For example, if I have a single constructor: public TestController(sting a = "") { /* blah */ } MVC has a fit saying that there are no parameterless constructors for TestController. How can I get around this? ...
I'm basically searching for a way to pass instances across programs/processes without serializing the instances, in .NET 4.0. Yes, I'm missing my good ol' 100% unsafe pointers ;) I thought the new integration of Memory-mapped files to .NET 4.0 would help me, having read somewhere that you could pass references/pointers "natively" using...

After some investigation we found that calls the app settings, in 1.1 apps, and the connection strings collection in 2.0 apps all failed. The config files had the values, but the code was returning null. After some head scratc...

I have recently heard "fanboys" of different .NET ORM methodologies express strong, if not outlandish oppinions of other ORM methodologies. And frankly feel a bit in the dark. Could you please explain the key merits of each of these .NET ORM solutions? Entity Framework NHibernate Subsonic ADO.NET Datasets I have a good understandi...
I'm attempting to develop an Interceptor framework (in C#) where I can simply implement some interfaces, and through the use of some static initialization, register all my Interceptors with a common Dispatcher to be invoked at a later time. The problem lies in the fact that my Interceptor implementations are never actually referenced by...
