excel - 更新到 VBA7 导致用户名和密码提示错误

Question

我有以下在 Excel 2010 中工作的代码（提示用户在打开工作簿时输入用户名和密码以及用“*”屏蔽密码）。我的 Excel 已更新到 Excel 2013，现在代码不起作用。在提示我输入用户名后，它会出现“类型不匹配”的错误，当我在 VBA 编辑器中查看时，会突出显示以下内容

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

随着AddressOf NewProc

下面的代码是打开工作簿时获取用户名和密码的整个序列。
