vba - 由于缺少引用xlam，Excel崩溃

Question

我有两个Excel文件(一个是xlam，另一个是xlsm)。 xlsm引用了xlam。

如果在打开xlam之前打开xlsm，Excel会崩溃。

从xslm(使用任何编程方法)开始，有一种方法可以检查xlam是否打开，如果没有打开，请动态加载它或显示警告，指出退出前必须先打开xlam。

我编写了一些代码，这些代码从xlsm中的Workbook_Open子句中调用

Public Function checkReferences() As Boolean
On Error Resume Next

Dim retVal As Boolean
retVal = False

Dim i As Integer

For i = 1 To ThisWorkbook.VBProject.References.Count
    With ThisWorkbook.VBProject.References(i)
        If StrComp(.name, "PreTradeServices") = 0 Then
            retVal = True
            Exit For
        End If
    End With

Next i

checkReferences = retVal
End Function

不幸的是，Excel在达到Workbook_Open之前崩溃了
