SQL Date/Time Table Selection

I have a database with a field set to Date/Time. My project has a variable that is of type Date. In a text box it displays 04/21/97. I cannot get the SQL statement to recognize it so that I can select those records with that date. I can use the format #4/21/97#. Help!
Dim SQLsource As String
    Dim stringTempDate As String
    stringTempDate = dateWeekEdit
    Text2.Text = stringTempDate
    SQLsource = "SELECT * FROM Timecard"
    SQLsource = "SELECT * FROM Timecard WHERE Empl_Number = " _
        & EmployeeNumber & " AND Wk_Ending = " & stringTempDate
        ' The above SQL statement has trouble using any date string
        ' to check against the Wk_Ending field which is set to Date/Time
        ' format.
    datTimecard.DatabaseName = App.Path & dbTimeCard
    datTimecard.RecordSource = SQLsource

You're on the right track using the pound signs; however, I would try it like this:

  SQLsource = "SELECT * FROM Timecard WHERE Empl_Number = " _
     & EmployeeNumber & " AND Wk_Ending = #" & stringTempDate & "#"
Let stringTempDate just be the date. Make sure that the Wk_Ending field is actually a Date/Time field and not something else. The pound sign trick only works on real date/time fields.
