I posted this question on CSharpCorner.com, but then realized I should
probably post it on a more active newsgroup. This will be my only cross-post.
I'm creating a game engine, and using CodeDOM for my scripting needs (I
realize I could use yacc or something else, but I wanted to try using CodeDOM
-- this is more of an exercise for me to learn this stuff).
Well, I compile my in-game scripts just fine. See appendix A for my code

I am using VB.NET 2003 and SQL Server 2000.
My program inserts new rows in a SQL table based on data read from a file.
I generated the commands and the stored procedures with the DataAdapter

The execution of the Insert Command throws the exception: "Object must
implement IConvertible. "
1. What object does it refer to? The Command itself?
2. On the other hand, in the VS Help file all IConvertible members have this

Collection editor problems.
I keep getting "Object does not match target type."
I think it has something to do with the TypeConverter, because it work fine
with-out it.

Anyone know whats going on? I don't get any real errors...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
