Hey All,
I just got ASP 2 Website programming. Im working through chp2. I have downloaded the chapter by chapter example code and am trying to work through the example. I have completed the chapter and when I run my website I get the following error. The code giving the error is code the book suggests, any ideas???

Thanks
Jeremy

Is there a "using System.IO"?

Hey,
Thanks for the response. I dont have the line: "using System.IO" in my helper.cs file. Should I put this somewhere?

Put it on top of the file (where all the other using .... items are

koen

Hey,
I added "using system.IO;". Now Im getting the following error:

As a side note: Is there perhaps a better set of chapter by chapter code for this book? Is it possible that since Im using WebDevExpress I dont have all the functionality required for the site?

Thanks for any input!

OK, so I have compiled the entire bit of code for chapter two as supplied by mythicalme. It works. I was attempting to read thru the chapter and copy and paste the bits of code as the text introduces em (who has the time to type every character??!!). Apparently this method doesnt work. Also Ive noticed small differences in the code between the book and mythicalme's code. I really wish that that a working and 'offical' version of the by-chapter code had been provided. It would be useful for learning to be able to build the project incrementally. I am surprised that this wasnt included. I will look for this in the next book i buy.

Thanks all
Jeremy

When you have issues with the code that is in the book, check the books Erratta (if there is one) as this normally includes changes to code that did not work and such.
