System.Data.OleDb.OleDbException: Unspecified error

[DaveRook]

Hello

I hope some one can point me in the correct direction to answer this. I have a website which runs with C#, accessing an Access (2007) database on my local computer via IIS. Everything works great.

Every now and then I get an unspecified error System.Data.Ole Db.OleDbExcepti on: Unspecified error) and I don't know why as nothing has changed (I have not touched the source code for weeks)!

Line 95:         siDA.SelectCommand = siCmd;
[B]Line 96:         siConn.Open();[/B]
Line 97:         siReader = siCmd.ExecuteReader();

To resolve this, I just open up the Web.Config file click control-s to save it, refresh my web page and it works!

The only way I can replicate this issue is by opening up a page and repeatedly click on the refresh button!

I can only assume this is not something to do with my code, but may be a setting in IIS?

Does anyone have any ideas what I've done?

Thank you

Dave

That almost assuredly sounds like a previous database connection was already open and was not closing properly.
Are you making sure you close the connection?
