What is the procedure to register, unregister (clean up) and handle events (clicks) from these menues? I have a clue it's something to do with the windows registry, but considering...
I am writing a .NET wrapper class for an existing native class which throws exceptions. What are the best practices for translating between native C++ exceptions and Managed exceptions? Catch and re-throw on a one-to-one basis (e.g. std::invalid_argument -> System.System.ArgumentException)? Is there a mapping already drawn up somewhere? ...
I've written a simple app in C# 2.0 using the .Net Framework 2.0 Serialport class to communicate with a controller card via COM1. A problem occurred recently were the bytes returned by the Read method are incorrect. It returned the right amount of bytes, only the values were incorrect.

When you use the WebBrowser control in .NET you can "embed" an instance of IE in your application, essentially making your own IE-based Web Browser. Does anyone know how to make any new windows created (like when the user selects "Open in New Window" from the context menu) open up in another Window of Your Web Browser Application, inste...
A typical stored procedure in our system accepts around 20 or so parameters. There's no chance of refactoring these stored procedures either. I've basically resorted to writing my own code generator that wraps these SP's into (database provider agnostic) "Command" objects, with their public properties corresponding to the SP parameters...

The issue manifests itself as an EXTREMELY slow repaint of the control (like 30 seconds for a full repaint), but only when it is on one of my screens. When on the other, the repaint speed is fine. I h...

Let's say I'm developing an application where memory usage varies extremely ...
