禁止关闭按钮和限制表格打开个数
起两种作用的代码都放在This workbook里的，实际只起到一种作用，请高手帮我修改修改,希望这两种代码都能在一个表你起到作用


第一个：只支持打开一个Excel表格
Private WithEvents app As Application
Private Sub Workbook_Open()
Set app = Application
End Sub

Private Sub app_WorkbookOpen(ByVal Wb As Workbook)
If app.Workbooks.Count > 1 Then Wb.Close False: MsgBox "本系统只支持打开单一文件！"
Application.Visible = False
End Sub

第二个：禁止关闭按钮，使用（点击）退出按钮
Dim BClose As Boolean
Private Sub Workbook_BeforeClose(Cancel As Boolean)
If BClose = False Then
Cancel = True
MsgBox "关闭已被禁止，请使用""退出""按钮关闭!", vbExclamation, "提示！"
End If
End Sub
Public Sub CloseWorkbook()
'ThisWorkbook.Close SaveChanges:=False
ActiveWorkbook.Save
BClose = True
Me.Close
End Sub

[解决办法]
对了,我新建了一个Workbook,在里面的ThisWorkbook里放了这些代码后保存,关闭.再打开时,你说的两个功能是都起作用的啊. 当然,如我选新建工作簿,你的程序是不会禁止的,因为并没触发app_WorkbookOpen事件嘛.你要想也禁止新建,需再加个
Private Sub app_NewWorkbook(ByVal Wb As Workbook)
Wb.Close False
MsgBox "本系统只支持打开单一文件！"
End Sub

VB code
