Hi,
I keep getting this error? Any suggestions?

An attempt to attach an auto-named database for file C:\Invoicing.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

The code is below

ObjConnection.ConnectionString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\Invoicing.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
