At the moment im learnig VB, Just cause its easy and still you can do pretty much with it, i have a project and i coded a login system, but my login system is using a Database thats in the file self, so people need to keep updating if there are more users (well, actually only the user it selfs but updating is handy cause it contains more then lol) so i was wondering if anyone knows how to make a database online and let the program retrieve data from it.

mysql is a decent free database software.

mysql(dot)com

You could use Access to create your database, but I'm not sure if you need an ODBC adapter for VB, I don't use VB much except in Excel macros.

Visual C# would be much easier to learn and there is current documentation out there detailing what you want to do. Your app could either be a webapp or a standalone program.

Storing mysql database information inside the client will lead you to disastrous results. If you want to build a connection between a database backend and your application, look into web services for .NET, they will be the best thing for you to use if you plan to have any database connectivity and such.

Keep in mind this will require your server to be .NET compatible meaning it will need to be a Windows server, or a Linux server with an emulated .NET environment. (Such as Mono.)

Alternatively, connect to a server who then connects to the mysql database or make a xAMP server and make web requests.

One common method to make a login system properly is to use MySQL. You can obtain a free database here: www.db4free.net. Have your client send data to the server, and have the server sent data back for the login system. Keeping MySQL inside the client isn't safe, somebody can easily grab your database credentials and your fucked.

Another way to do it is to keep a file record of the users uploaded on a server, w/e. Then download the file or open it and read from it, and compare matches. This method works but isn't the best method, as it can easily be hacked and username / password information can be leaked. If you are interested in this method, I suggest you MSDN URLDownloadToFile().

You can make the program check online in a text file.

I'm going to re-encourage you to rethink this.

You will need to have the MySQL info hardcoded into the application is you have no middle-man script or service to use with your application. Meaning your database is at extremely high risk of being hacked and destroyed.
