Connecting To SQL Database

Feb 8, 2012

I am a wannabe programmer but quite new, started with VB.net about 1 month ago.I write on this forum because It's the first time that I'm actually stuck. The problem is I cannot find a way to connect to SQL server database I have created and saved earlier on my HD using visual express 2010. I want to find a way to connect using code, not by click and drop. I just hope you won't find my issue too trivial to even answer it.The project is very simple, it just consists of a button that should connect to the db on click.[code]

Connecting ComboBox To Database?

Apr 1, 2010

i'm fairly new to VB and am doing my second system through it. I am at the point where i want to link a combobox on my form to my access database so that when i click the dropdown arrow a list of surnames from the particular table in my access database appears.

[Code]...

First things first is this code remotely close to doing what i want it to do? I have to use an access database and i am familiar with this particular method of connecting to the database (sending any data to it is easy now). Secondly when the form opens (since the sub is called at load) i get the annoying old "object reference not set to an instance of an object" message.
