问题
I'm having a number of issues, and the current one is overcoming a security exception when using iTextSharp.
This article http://www.junlu.com/list/27/763977.html
To which I was directed following this question I posted yesterday:
Displaying a bar code with iTextSharp using Chris Love's Barcode Handler (2 part)
Seems to be what is required to overcome my problem. But I have searched and searched and cannot find a definitive and simple answer to the question "How do I compile a DLL"
So, having made the suggested modification to iTextSharp, I need to make it into a single DLL.
I have absolutely no idea how to do this, despite an hour of Googling!
I'm using Visual Web Developer 2010 Express. Which according to my searches does not have any built in capability to do this. So... how do I?!
Do I NEED to download Visual Web Developer Pro? I can surely download the free trial and use that, but going forward, I don't especially want to have to download a pay-for program to do this as it's a rare occurrence for my needs.
