what does it mean ...MessageBox.Show("opened connection to {0} ", mySqlConnection.Con

It displays the connection string as the title of the message box..I didn't understand what it means by {0}.

thanks

The Second Argument for the MEssageBox Function is the Titlebar String.

Regular Expressions are not applicable in messagebox. Regular Expressions are applicable only in formatting the strings not here. Try to change the code like this.

MessageBox.Show("opened connection to : " & mySqlConnection.Con )

don't know what they are ...
