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?]]> Fri, 04 Apr 2014 07:36:12 +0000 http://www.quickpdf.org/forum/nullreferanceexception-was-unhandled_topic2859_post11599.html#11599
