I currently have a relatively small (4 or 5 tables, 5000 rows) MySQL database that I would like to convert to an sqlite database.

(I have complete admin access to the database/machines...

What is the approved way to convert from char* to System::string and back in C++/CLI? I found a few references to marshal_to<> templated functions on Google, but it appears that this feature never made the cut for Visual Studio 2005 (and isn't in Visual Studio 2008 either, AFAIK). I have also seen some code on Stan Lippman's blog, but it...
I am currently working on a project that is moving from .NET 2.0 to 3.5 across the board. I am well aware that 3.5 is basically a set of added functionality (libraries, if you will) on top of what 2.0 offers. Are there any gotchas that I might hit by simply re-targeting the compiler to 3.5? ...

In Jesse Liberty's Learning C# book, he says "Objects of one type can be converted into objects of another type. This is called casting." If you investigate the IL generated from the code below, you can clearly see that the casted assignment isn't doing the same thing as the converted assignment. In the former, you can see the boxing/un...
