I would like to know, how do I check if dbCon.Open is open so I don't re-open it, and if dbCon.Close is realy closed otherwise I have to close it.
 
I know there's a method, but can't find it.

If con.State = Data.ConnectionState.Open Then
con.Close()
End If

This is logically correct but if you use use connections right you should never need it.

Thanks Michael it works fine, however I notived the .Dispose() method, is it safe to use this:
 
            dbCon.Open()
            dbCmd.ExecuteNonQuery()
            dbCmd.Dispose()
            dbCon.Close()
            dbCon.Dispose()
 
I'm disposing after I'm done with it, dbCon and dbCmd are objects that I then dispose of, in the case of dbCon I am closing the connection, is it beneficial to also dispose of it?

99% of the time it's beneficial to dispose of any object once you're certain you have finished with it. A closed connection can still be occupying resources, a connection that has been closed and disposed is no longer open and no longer occupies resources.
