我用VBA寫了壹個，妳參考下吧。呵呵。效果：根據打開文件時的日期，提醒後7天的日程。
實現步驟：在工程資源管理器中的thisworkbook上雙擊，在彈出的代碼框內寫下代碼：
Private Sub Workbook_open()
Dim x, i As Integer
Dim thedate As Date
Dim str As String
Dim str1 As String
xr = Cells(65535, 1).End(xlUp).Row
For i = 2 To xr Step 1
thedate = Cells(i, 1).Value
x = DateDiff("d", Now, thedate)
If x <= 7 Then str1 = Cells(i, 1) & ":" & Cells(i, 2) Else str1 = ""
str = str & Chr(10) & str1
Next
MsgBox "最近7天要做的事：" & str
End Sub
