Steven,

Thank you for your response. I will answer your questions:

I have not changed the block's code! When I said that I changed some
features, I meant in my program that uses the block, not that I made changes
to the block.

I will have to take-back what I said about other programs having a problem
with the block. I checked again and now things seem to run fine in other
applications. So, the only problem seems to be in the one application I am
working with here.

Even though I only have the block referenced and not included as a project
in my solution, when the error happens VS.NET allows me to open the
SQLHelper.vb interface to show me where the error happens. This is the most
confusing part: as I stated in my previous email, the error happens on line
460:

This is very strange. I had this type of thing happen in the past, but the
cause was that there was a code-behind that had the same class in it as
another code-behind. I don't think that is the case here. I don't know if
this is related, but there are 5 lines in my task list that I do not know
how to clear. Maybe these have something to do with the problem or will
give you a clue. Here they are:

1) Could not copy temporary files to the output directory
2) The file 'busForms.dll' cannot be copied to the run directory. The
process cannot access the file because it is being used by another process.
3) The file 'busForms.pdb' cannot be copied to the run directory. The
process cannot access the file because it is being used by another process.
4) Warning: The dependency 'busForms, Version=1.0....., Culture=neutral'
in project 'Forms1' cannot be copied to the run directory because it would
overwrite the reference 'busForms, Version= 1.0...., Culture=neutral'.
5) Warning: The dependency 'Settings, Version=1.0....., Culture=neutral'
in project 'Forms1' cannot be copied to the run directory because it would
overwrite the reference 'busForms, Version= 1.0...., Culture=neutral'.

Please consider the line the code is stopping on and the error messages. I
hope this information leads us to a fix. Please let me know what you think.

Thanks,

Schoo
