Question

我有以下代码可在Excel 2010中使用（提示用户在打开工作簿时输入用户名和密码，并用“ *”屏蔽密码）。我的Excel已更新为Excel 2013，现在代码不起作用。提示我输入用户名后，“类型不匹配”错误，当我在VBA编辑器中查看时，以下内容突出显示

Public Function InputBoxDK(Prompt, Optional Title, Optional Default, Optional XPos, _
Optional YPos, Optional HelpFile, Optional Context) As String

与AddressOf NewProc一起

下面的代码是打开工作簿时获取用户名和密码的整个过程。

更新到VBA7会导致用户名和密码提示错误
