This simple project will simply insert a null value to a date/time field if the checkbox within DateTimePicker is False.
In order to determine if the Checkbox is true/false you need to use the isNull function.
Private Sub CmdInsert_Click()
Dim cn As New Connection
Dim strSQL As String
cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.Path & "\Data.mdb;"
strSQL = "INSERT INTO NOSOld (Name, Specialization, Date_of_NOS, Date_Encoded, Case_Officer, Notes, Status) " _
& "VALUES ('MORENO, JOSAPED', 'HACKER', " & IIf(IsNull(DTPicker1), "Null", DTPicker1.Value) & ", " & IIf(IsNull(DTPicker2), "Null", DTPicker2.Value) & ", 'AVECILLA, PAUL VINCENT', 'ENCODED BY SEM', 'OLD')"
Debug.Print strSQL
cn.Execute strSQL
MsgBox "Record inserted successfully...", vbInformation
End Sub
I created this sample project to answer the question of shaolin at http://www.sourcecodester.com/forum/inserting-a-null-value-dtpicker-ms-access-db-with-a-datetime-field-type.
