What is "dsCustomers" exactly?
The declaration seems to specify that it's a class in the BoundMySQLTest namespace,
but a name like this I personally would use to specify a variable pointing to
a DataSet that contained "customer" details.

The "codebehind" is used by VS.Net and you run it (locally) by compiling
the codebehind into a dll that is then used.
When you upload all sourcefiles (aspx.cs) and no dll's (see bin directory)
then it needs to be changed to "src" so that the system can again find the
codebehind files and compile them.
Within VS.Net there is a "Copy Project" function to send all files needed
to a webserver. This will include the compiled dll's and exclude the .cs
(as they are not needed). Make sure that all support files (like xml files)
that you want to have at that webserver have a "build action" of "content"
instead of "none" (see file properties).
