as long as the dll and main exe in the same folder, the dll shud be able to
pick the conf up.

Hi,

I don't really remember if you can get it using
ConfigurationSettings.AppSettings from the dll, I assume you tried this
right?

The other option you have is store this info in a static member of your
connection class from the Data dll.


cheers,
 
I have the main project that where is my app.config. I have a project dll
called Data, that must to read from the app.config that belongs the main
project a string connection. When i debug thats returns null. How can i read
my connection string. I´d like a sample or a link that i could download it.
Thanks

In fact, in a prj that im workin on. the main exe just a 'kick start' single
file with a bunch of resources. ALL functions have been built by DLLs
(roughly 8 prj DLLs). I hav never seen prob like this.
 
Hi,

I think the same, if the dlls are in the same appdomain then they should
"see" the ConfigurationSettings.AppSettings cause it's static and visible in
the appdomain.

You should be able to get at any entry in the
<configuration><appSettings> section from your DLL by

1) adding a "using System.Configuration" to your using clause

and
2) Specifying
string myItem =
ConfigurationSettings.AppSettings["MyConfigItem"]

Can you SHOW us the app.config of the main app, and the relevant code
lines in your DLL?

If it is in a different section of the Configuration file, the
ConfigurationSettings class and the System.Configuration namespace have lots
of methods for reading Configuration settings.
