如何使用MS Access 2016在VBA表达式中编写数字字段？

Question

I have a code line referencing a field as a Date format. I need to reference another field as numeric format.

This is my code for a date format field:

Private Sub cmbsearch_Click()
Dim varFilter As Variant, stdcard_id As String, txtname As String, txtrecord 
As String, strTableName As String
strTableName = "tbl01"
    If IsNull(Me.stdcard_id) Then
        Me.stdcard_id.SetFocus: Exit Sub
    End If

varFilter = "[dateofbirth]= # "& Forms!frm_stid_name_record & "#"
....
End Sub

This is my code line for a numeric format field, but I don't know to write the code after the "=" symbol

varFilter = "[std_id]="

Answer 1

try

Dim stdid As Long

stdid = Val(Forms!frm_stid_name_record)

varFilter = "[std_id]=" & stdid & " "
