主题：没看明白代码

生日提醒代码如下：

Dim ids As String
Dim n As Integer = 6 '未来天数,含今天,所以实际是未来7天
For Each dr As DataRow In DataTables("员工").DataRows
    Dim dt As Date = dr("出生日期")
    Dim dt1 As New Date(Date.Today.Year,dt.Month,dt.Day)
    Dim dt2 As  New Date(Date.Today.AddDays(n).Year,dt.Month,dt.Day)
    If (dt1 >= Date.Today AndAlso dt1 < Date.Today.AddDays(n)) OrElse (dt2 >= Date.Today AndAlso dt2 < Date.Today.AddDays(n)) Then
        ids = ids & "," & dr("_Identify")
    End If
Next
If ids > "" Then
    ids = ids.Trim(",")
    Tables("员工").filter = "[_Identify] In (" & ids &")"
End If

为什么有了日期变量dt1了，还设置日期变量dt2？没看明白。

明白了，谢谢！
