• Provide a URI as a parameter for an ODBC or OleDB provider connection string?

  - by womp

  Is there any way of specifying a URI (rather than a physical path) as the "Data Source" parameter in an OleDB connection string, or the "Dbq" parameter in an ODBC connection string, such that the default ADO.Net providers will work with it? I've tried file://, and it's a no go, so I just wanted to confirm whether or not this is possible. I'm guessing not, but any confirmation or documentation links would be appreciated.

• What's the best way to reference a .DLL - as a normal reference or as a web service?

  - by dotnetdev

  Hi, What is the best way to reference an existing .NET dll (Class library)? Is there any benefit to expose web services from the class library and reference these as opposed to referencing the actual .dll (Although one benefit of the web service approach is the granularity and thus surface area exposed is up to you at coding time)? I am thinking with loose coupling in mind, as a criteria. Thanks

• Must web apps support back button?

  - by Patrick Peters

  I did a system test on a new ASP.NET app. I encountered several exceptions when using the BACK button in my browser (IE 7). I stated in a review-record that the web-app must support the use of a BACK button (or at least handle it gracefully with for example session-time out warnings). The teamlead did not agree with me as he stated that a web-app should not support working with the back-button by default. Do you agree?
