I test if it is dirty and then usually just undo (since this is used only the dev environment). Hated clicking cancel 50 times.... Doug, Glad you got it working!

I like this better because it gives me control ahead of time as to which environment I log into. This code is added in my Program.cs file in ShowLoginAndInitMainForm method. It will only fire if I'm running from VS. #if (DEBUG) if (ConnectionManager.ShowAvailableConnectionStrings()) ConnectionManager.SetConnections(); #endif

E Group: StrataFrame Users Posts: 2.4K, Visits: 23K	Greg McGuffey (07/09/2009) I do something very similar. The only thing I have added to this is a check to see if the form is dirty, with code to handle that situation. Hi Greg, I am assuming that when calling form.Close() that if the form is dirty it will ask you if you want to save the changes. I have not tested, but took that assumption for granted . Can you please elaborate on why are you handling this? Edhy Rijo

I allow this only for developers and it allows me to have multiple "dev" environments, as I can setup multiple connections, then just choose which I want. E.g. I have a local connection, which attaches to a local db and I have a remote connection that attaches to a db in our data center.

E Group: StrataFrame Users Posts: 2.4K, Visits: 23K	Hi Doug, I use the following routine from a menu option so my users can change the database connection. Private Sub SetDatabaseConnection() '-- Check security for this module If Not CheckSecuritySecurityIsGranted("DatabaseConnection") Then Exit Sub End If '-- Show the connection dialog and allow a connection to be selected If MicroFour.StrataFrame.Data.ConnectionManager.ShowAvailableConnectionStrings() Then '-- Since a connection was selected, then all of the existing dialogs need to be closed ' since their connection is established to the original source. For Each loForm As Form In Me.MdiChildren loForm.Close() loForm.Dispose() Next '-- Force the connections to be reset MicroFour.StrataFrame.Data.ConnectionManager.SetConnections() End If End Sub Edhy Rijo

Group: Forum Members Posts: 39, Visits: 225	Is there a way to switch database connections such that I can jump from a development database to a production database, and back again? I know that I can remove the AppKeys.dat and Connections.dat files to remove the connections and then re-initialize via the Connection Wizard. But this also wipes out all connections rather than a specific one. Thanks.
