Getting data into a vb.net form from Access database

Hello,

Would this code work? I am trying to count the number of "A" entered in the Response field.
the database is called Survey.
   
Dim number As Integer
        Dim con As OleDbConnection
        Dim comm As OleDbCommand
        Dim reader As OleDbDataReader
        con = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Survey.accdb;")
        comm = New OleDbCommand("Select count(Response)as number from Answers where SurveyID = 1 and QuestionID =1 and Response = 'A'", con)
        ' Open Connection
        con.Open()
        ' reader read comm
        reader = comm.ExecuteReader
        ' Get from the reader the UserName and UserPasswrod
        While reader.Read
            number = reader.Item("Response")

        End While
        con.Close()

Because you are using Count this should only return one value, and you don't need execute reader, what is the error you are getting?

add a space before "as"

comm = New OleDbCommand("Select count(Response) as number from Answers where SurveyID = 1 and QuestionID =1 and Response = 'A'", con)

or in access vba, just not sure if it will work on .net

comm = New OleDbCommand("Select count("*") as number from Answers where SurveyID = 1 and QuestionID =1 and Response = 'A'", con)

To tell you the truth I haven't tried it yet....
I'll do that now and get back to you
or you can try this...

 Dim conn As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\survey.accdb;Persist Security Info=False"
        Dim cmd As String = "Select Count(response) as iCount from Answers Where surveyID=1 and questionID=1 nad Response='A'"
        Dim adapter As New OleDbDataAdapter(cmd, conn)
        Dim rs As New DataSet
        adapter.Fill(rs)

rs.Count as well as rs("iCount") should tell you the total number of people who chose a.
This the error i am getting

The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect
there is a spelling mistake in your code. change the nad to and before Response='A'"
rbgCODE:

It looks like it's working. The thing is I don't know how to extract the value contained in "rs".

Is it possible to do some thing like:
dim count as integer = rs.value....???
check the below link. you will get the basic idea

you can get the values as below

rs.Fields(0).Value


I get the following error:

Fields is not a member of system.Data.Dataset
sorry I posted the vb6 codes.
