Dim rg As Range


Set rg = ws.[c9]


If Text1.Text = "123456" Then


MsgBox "欢迎进入VBA数据库开发课堂", vbOKOnly + vbInformation, "提示"


rg = "你对知识的渴望正是我们生生不息的源动力"


rg.Font.Color = RGB(255, 0, 0)


rg.Font.Name = "宋体"


rg.Font.Bold = True


rg.Font.Size = 12


Unload Me

Text1.Text = ""


Text1.SetFocus '获得焦点


End If


End Sub


2、用户窗体“取消”按钮代码

ActiveWorkbook.Close (False) '不显示保存对话框


End Sub


3、模块使用期限（syqx）代码


Sub drrj()


'不让屏幕刷新


Application.ScreenUpdating = False


Dim i As Integer


Dim x As Integer


Dim n As Integer


drsj.Visible = xlSheetVisible


'统计当前数据区域的总行数


i = drsj.[a1].CurrentRegion.Rows.Count


'如果错误就跳过


On Error Resume Next


If drsj.[a1] = "" Then


drsj.[a1] = Now


drsj.Visible = xlSheetVeryHidden


Exit Sub


End If


drsj.Cells(i + 1, 1).Value = Now


x = drsj.Cells(i + 1, 1).Value - drsj.Cells(i, 1).Value


n = drsj.Cells(i + 1, 1).Value - drsj.Cells(1, 1).Value


drsj.Visible = xlSheetVeryHidden


If n > 60 Or x < -1 Then
