I created a database in access 2007, linked it to my project in visual studio 2008 (vb). When I enter some data using the UI, it does not save it in the database, and it's gone as soon as I run the program again. I dragged the textboxes from the datasource panel, onto the UI..
this is the code that was automatically generated by vs for the save button:

So I'm having more database problems. The specific problem I am having is that I am trying to update a DataGridView to display new information that was input into the database programmatically. I have tried several methods, but none have worked, and one actually "broke" the program. So I am in need of some more assistance.

I have been tasked by my boss to create an application that takes information from an excel database holding sales figures, margins, budgets etc calculates all the figures and exports the totalled values to a table and graph also in excel. Although this is fairly easy, there is some complications I am dealing with.

What I am trying to do is get specific info from a database and what I am getting is the first entry.
I have made a database connection, made the top bar not visible and I have inserted a text box and multiple labels. My MDB database has 3 columns (street, city, postcode) and multiple rows.
What I want is when a user enters a postcode in the text field the other labels get the info related to it. I.E. when a user enters "FY1 3DL" the labels update to "King street" and "Blackpool". With the code below I get the first row from the database.
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

I want to populate a combo box but not using a database
e.g. combobox displays
red
white
blue
But want I want is if a person chooses red I want to pass back the number 1 value to a backend database. I'm able to populate a combo box with the colours but not sure how i 'grab' the value to pass back
Dim colours as string[] = new string[] { "red", "white", "blue" }
m_cmbColours.Items.AddRange(colours)
What I want is this
value Colour
1 red
2 white
3 blue
Combobox just displays the colours and when chosen in the combo box I grab the value corresponding to colour chosen.
I've given up on my harder stuff and have simplified it to something else. There are no errors that pop up now but the list box doesn't populate! I took the code from a book and there's a data adapter, data connection, and data set on the form already (they're not named in this code though, since the book didn't say to). When the program opens, the list box has a line of text in it and the list box doesn't fill with the right items.
