View 1 Replieshow to create modules and consequently how to use them.I need to do a database in mySql from vb.net. I have tried the usual way, that is my connecting to the database at the beginning of each of my class. I want to know if that can be done through modules, as far as i have read about that or some other way like procedures and functions. In that way, it could ease my coding in not having to write the db connection each time.

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

I am trying to make a very simple program that connects to a MySQL database using VB.NET. My program only has one form and one label. I setup my MySQL database to have a table and one field (a VARCHAR)called "Tab1". I manually inserted the value "CLOSED" into the Tab1 field using PHPMyAdmin. I want my program to change the value of the field to OPEN/CLOSED and I also want the label text on my form to change too when it's clicked.

View 2 RepliesI'm populating a DataTable from a MySQL-server. One of the columns contains norwegian characters (�, �, �), but they don't display correct in my datatable. I've been searching google for some answer, but I haven't found any. I've never had this problem before. Actually I'm not quite sure exactly where the problem is. It's either in the datatable or in the MySQL .NET-connector as far as I can tell. If I do the same query in the MySQL Query Browser, the characters are shown correctly, so it can't be the server.
