I am attaching an image to a listview from code behind, the image depends on a value from the database and there are 5 different images.It sometimes works fine and then will randomly come up with an error, when nothing has changed, the error is:[Code]....
It doesn't seem to make sense to me because ImageUrl IS a member of image. Here is my code:

And code behind: [Code]....
I can't figure out why it won't publish the database to my hosting account. I have an SQL server set up with a username and password, etc. but I don't understand why it won't connect.
It keeps giving me an "Invalid URI" error. I don't know what to do or what to look for.
I'm just learning ASP.NET and I don't understand what it wants besides what I've given it already.
i do have an app_code folder, which contains a base.cs, which is intented to have its class page_load to override other .aspx-files (without masterpage.master) when the page_load-class of these files is loaded. i wrote the class in base.cs as "public override page_load", but this gives an error when compiling. what am i doing wrong?
