>My guess is that the XML string being passed around in your C routine is where the problem is. I'm no expert at reading C, but I noticed your routine has some calls to subroutines that receive parameters. I think one of those parameters is where the problem is. If you can capture the XML string at the point of this error and locate line 1 position 293, you'll probably figure out the problem.

Thanks, Barbara, I'll give it a shot.

For the life of me, however, I can't understand why it works in .NET design, but doesn't in the situation I presented.
