I've been working away programming and debugging as I go. Everything working as expected. I'm using a Dataset. I find I don't need 2 of the original column names so I delete 1 and change the name of the other. I try to run the code again and I get the error "NullReferanceException was unhandled" at QP.LoadFromFile(MyPDF, ""). MyPDF does contain the path string.

So, I change the column name back to original and add another column using original name and it works. I add a new column and it works. I change new column name and it continues to work.

I don't understand why/how QP can know or even care columns are changed.

Ideas?

Oops! It is probably important to let you know I'm programming in 2010 vb.net;-)
