Webpart with custom .DLL

Jul 16, 2009 at 9:33 PM


I still new to Sharepoint.  I have a custom .dll that handles common tasks for me.  I was wondering if I could include the .dll in the solution.  What do I need to do, so that the .dll is deployed with the solution on Sharpeoint? 


Also, how does one normally access the sql connection string in a Sharepoint environment.  I have tried to edit the web.config file, that doesn't seem to work. 

Thanks for any help you can provide.
