Establish A Connection To MySQL Via VB & Display Simple Query Results On A Form?

I have a project in Visual Studio 2008 and there is a working data connection to a MySQL database. In other words, I can query the db directly from Visual Studio and it will display the results.

I've tried a couple of approaches that I found online for writing a connection string and accessing the db, but no luck yet.

All I'm trying to do is code a button to query the db and then reset the text property of a label/textbox to display the results based upon another label/textbox value.

The pseudo-code I am imagining is something like this:

Private Sub query_submit_button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles query_submit_button.Click
result_textbox.Text = SELECT field FROM table WHERE otherfield = key_textbox.Text
End Sub

I didn't see any related questions posted on SO - forgive me if I missed one that already exists and this is a dupe.

What is the correct way to accomplish this?

EDIT
Using MySQL 5.1
