Verynewbie: Retrieve Single Value From DB?

Hi All: I'm just trying to migrate from vbScript to .net and am trying to retrieve a single value from a dB based on a value passed in a form. I can't seem to find the right tutorial to explain this to me, and am open RTFL'ing any links!

What I have thus far is:


Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)


Dim strConn As String = "server=myServer;uid=myUID;pwd=myPWD;database=myDB"

Dim myQuery As String = "Select myVal FROM myTable WHERE myID= " & lbmyID.SelectedValue

Dim myConn As New SqlConnection(strConn)

Dim myObj As SqlDataReader

Dim cmd As New SqlCommand(myQuery, myConn)

myConn.Open()

myObj = cmd.ExecuteReader(System.Data.CommandBehavior.SingleRow)

Dim myReturnedValue As String = myObj.....

myConn.Close()

end sub

I feel like I'm close, but I'm stuck on how to get the value returned by the query into "myReturnedValue"...if this is the wrong approach please let me know!
