Hello. I have a winforms datagridview that seems to always have at least one row selected all the time. I'm not interested in being able to select the rows at all really, I just need the user to be able to select the checkbox in column 1. Any ideas why there is always at least 1 row selected?

It reads each line of the source file, checks to make sure that it parses into a valid email address/zip code, creates a sql insert command, adds it to a string builder and eventually executes it. I want to do a single execute inst...

I've seen Castle DynamicProxy which looks like it fits the bill, but the documentation isn't great. I'm also surprised that this kind of thing isn't in the .Net Framework itself. Does anyone: K...
We have a very large project mostly written in C# that has some small, but important, components written in C++. We target the RTM of .NET 2.0 as the minimum required version.
