Just a guess, I think here's what happened: x=-1 y=x++ + ++ x; // x= -1 x++ has the most precedence, so it becomes: y= (-1) + ++x; // x = 0 ++x is next: y = (-1) + (1); therefore the result is 0. It is interesting to compare this with: x = -1; x += x++; Which will give -2, in my mind the += operator works like: int tmp = x; x = tmp + x++; Hope this helps and the above is correct... Adrian

I thought x gets inceremented only AFTER the = operator (for #1, x++), isn't that what's pre and postfix notation all about... Oh well... :roll: I thank you and Adrian.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
