Question

我设置了一个全局字典对象来跟踪文件路径（键是“项目名称”，这是文件名的第一个单词）。该程序的工作方式是打开一个表单，然后用户可以打开文件对话框将文件添加到列表框中。完成后，它应该添加字典的名称和路径。

主要代码：

Public project_dict As Scripting.Dictionary

Public Sub excelToPPT()
Set project_dict = New Scripting.Dictionary
...
Dim u As UserForm1
Set u = New UserForm1
u.Show
...
End Sub

UserForm代码：

Private Sub cmdAddProject_Click()
    Dim project_fd As FileDialog
    Set project_fd = Application.FileDialog(msoFileDialogFilePicker)
    Dim it As Variant
    Dim path_split() As String
    Dim f_split() As String
    Dim f As String

    With project_fd
        .AllowMultiSelect = True
        .Title = "Select project excel file(s)"
        .Filters.Clear

        If .Show = -1 Then
            For Each it In .SelectedItems
                path_split = Split(it, "\")
                f_split = Split(path_split(UBound(path_split)))
                f = f_split(0)

                ' WHERE ERROR OCCURS
                project_dict.Add f, it

                Me.ListBox1.AddItem f
            Next it
        End If
    End With
End Sub

运行此错误时

project_dict.Add f, it

是不好的，因为project_dict不是我在这种情况下假设的范围问题的对象。有什么想法吗？

通过将以下属性放在UserForm代码中并将字典传递给表单而不是使用全局变量来解决该问题。

Dim project_dict As Scripting.Dictionary

Public Property Get ProjectDictionary() As Scripting.Dictionary
    Set ProjectDictionary = project_dict
End Property

Public Property Let ProjectDictionary(ByVal pd As Scripting.Dictionary)
    Set project_dict = pd
End Property

用户表单sub看不到的全局变量
