I am using [Description("A description")] in my code.
I want to be able to reference a text string within my "Resource file" like
this:
[Description(MyA pp.Properties.R esources.strADe sciption)].
The issue is that Description requires a constant string. Is there anyway
to reference my resource file to get the strings desired for "Descriptio n"?

No - one of the things about attributes is that their values are
absolutely constant, baked into the assembly. You can't use properties
or anything like that.
You could autogenerate your file, perhaps, to get the descriptions,
but that would be a fairly extreme measure.

Steve,
In this case, I would derive a class from the Description attribute and
then have the constructor take a key that you can use to get the appropriate
resource.
Once you have it, you can set the DescriptionValu e property in the
constructor (it is protected) to the value from the resource.

Can I refer you to how MS do it (via Reflector)? They have a subclass
of DescriptionAttr ibute, which updates itself at runtime; they then
use [SRDescription(" res name")]; worth a shot...
[AttributeUsage( AttributeTarget s.All)]
internal sealed class SRDescriptionAt tribute : DescriptionAttr ibute
{
// Fields
private bool replaced;
// Methods
public SRDescriptionAt tribute(string description) :
base(descriptio n)
{
}
// Properties
public override string Description
{
get
{
if (!this.replaced )
{
this.replaced = true;
base.Descriptio nValue =
SR.GetString(ba se.Description) ;
}
return base.Descriptio n;
}
}
}

There are various ways of doing it. Here's one simple way I came up with for my own code (adapted for your example). Just pass the name of the resource as a literal (e.g., "strADescriptio n"). It could stand a little work if you really want to make it completely portable/generic (and to safeguard against changes to resource names) but it does the job.
using System.Componen tModel;
using System.Reflecti on
using MyApp.Propertie s;
class DescriptionReso urceAttribute : DescriptionAttr ibute
{
public DescriptionReso urceAttribute(s tring resourceName)
: base((string)ty peof(Resources) .InvokeMember(r esourceName,
BindingFlags.Ge tProperty | BindingFlags.No nPublic | BindingFlags.St atic,
null, null, null))
{
}

Greetings, all!
I have a project for work, and I'm not sure how to efficiently do what I
need to do. I'm hoping someone out there can help.
Project is this: I'm creating a web-based interface where people at my
company (operators) can enter data for service calls. All data entered
is run thru one or more PHP scripts for error checking and then stored
in a MySQL database on a server here in the office.
