    Unanswered: Setting a Parameter Query in VB code


    I currently have some code that runs a query and sends an email via outlook from that query. However I want to be able to set a parameter in the query, i have read online that you need to set the parameter in the Visual Basic code as well but i literally have no idea how and what i read online seem quite confusing!

    This is the code i have at the moment:

    Private Sub Command80_Click()
    Dim MyDb As DAO.Database
    Dim rsEmail As DAO.Recordset
    Dim sToName As String
    Dim sSubject As String
    Dim sMessageBody As String
    Set MyDb = CurrentDb()
    Set rsEmail = MyDb.OpenRecordset("qry_InductionLetter", dbOpenSnapshot)
    With rsEmail
            Do Until rsEmail.EOF
                If IsNull(.Fields(6)) = False Then
                    sToName = .Fields(6)
                    sSubject = "Invite to World of Work Induction Course:  " & .Fields(10)
                    sMessageBody = "Dear " & .Fields(0) & " " & .Fields(1) & "," & vbCrLf & vbCrLf & _
                    "Thanks," & .Fields(11) & vbCrLf
     DoCmd.SendObject acSendNoObject, , , _
                        sToName, , , sSubject, sMessageBody, False, False
                End If
    End With
    Set MyDb = Nothing
    Set rsEmail = Nothing
    End Sub
    This sends an induction letter to the candidtates in the qry_InductionLetter. At the moment the query brings back everyone was is eligible for the Induction even if they have already attended, so for my parameter i need the user to choose which course they want to attend as i dont want letters to be sent out to the same candidates each time.

    Thanks for any help in advanced!

    You CAN set params in code. But it's easier to set the params in the query via forms.
    The query reads a form to get the params.
    'where [myFld] = '" & forms!frmMain!txtBox & "'"

    BUT if you want to go the code route...
    set qdf = currentdb.querydefs("qsQry")
    qdf.parameters("Enter Start Date") = #1/1/2014#

    I know how to set the parameters in the query but when i have done this, i get the following error message in the code;

    Run time error '3061'
    Too few parameters. Expected 1.

    Basically i want to somehow adapt my existing code to allow the query to have a parameter.
