excel - 使用 VBA 在 Excel 中刷新对 VBProject.VBComponents 所做的更改

Question

在以编程方式删除模块然后从文件中重新导入它们时，我在 Excel 中遇到了一些奇怪的问题。基本上，我有一个名为 VersionControl 的模块，它应该将我的文件导出到预定义的文件夹，并根据需要重新导入它们。这是重新导入的代码(问题如下所述):

Dim i As Integer
Dim ModuleName As String
Application.EnableEvents = False
With ThisWorkbook.VBProject
    For i = 1 To .VBComponents.Count
        If .VBComponents(i).CodeModule.CountOfLines > 0 Then
            ModuleName = .VBComponents(i).CodeModule.Name
            If ModuleName <> "VersionControl" Then
                If PathExists(VersionControlPath & "\" & ModuleName & ".bas") Then
                    Call .VBComponents.Remove(.VBComponents(ModuleName))
                    Call .VBComponents.Import(VersionControlPath & "\" & ModuleName & ".bas")
                Else
                    MsgBox VersionControlPath & "\" & ModuleName & ".bas" & " cannot be found. No operation will be attempted for that module."
                End If
            End If
        End If
    Next i
End With

运行后，我注意到有些模块不再出现，而有些模块有重复(例如 mymodule 和 mymodule1)。在单步执行代码时，很明显，一些模块在 Remove 调用之后仍然存在，并且它们仍然在项目中时被重新导入。有时，这只会导致模块以 1 为后缀，但有时我同时拥有原件和副本。

有没有办法刷新对 Remove 和 Import 的调用，以便它们自己应用？我正在考虑在每个之后调用一个 Save 函数，如果 Application 对象中有一个函数，尽管如果在导入过程中出现问题，这可能会导致损失。

想法？

编辑:将标签 synchronization 更改为 version-control。

这是一个实时数组，您在迭代期间添加和删除项目，从而更改索引号。尝试向后处理数组。这是我的解决方案，没有任何错误处理:

Private Const DIR_VERSIONING As String = "\\VERSION_CONTROL"
Private Const PROJ_NAME As String = "PROJECT_NAME"

Sub EnsureProjectFolder()
    ' Does this project directory exist
    If Len(Dir(DIR_VERSIONING & PROJ_NAME, vbDirectory)) = 0 Then
        ' Create it
        MkDir DIR_VERSIONING & PROJ_NAME
    End If
End Sub

Function ProjectFolder() As String
    ' Ensure the folder exists whenever we try to access it (can be deleted mid execution)
    EnsureProjectFolder
    ' Create the required full path
    ProjectFolder = DIR_VERSIONING & PROJ_NAME & "\"
End Function

Sub SaveCodeModules()

    'This code Exports all VBA modules
    Dim i%, sName$

    With ThisWorkbook.VBProject
        ' Iterate all code files and export accordingly
        For i% = 1 To .VBComponents.count
            ' Extract this component name
            sName$ = .VBComponents(i%).CodeModule.Name
            If .VBComponents(i%).Type = 1 Then
                ' Standard Module
                .VBComponents(i%).Export ProjectFolder & sName$ & ".bas"
            ElseIf .VBComponents(i%).Type = 2 Then
                ' Class
                .VBComponents(i%).Export ProjectFolder & sName$ & ".cls"
            ElseIf .VBComponents(i%).Type = 3 Then
                ' Form
                .VBComponents(i%).Export ProjectFolder & sName$ & ".frm"
            ElseIf .VBComponents(i%).Type = 100 Then
                ' Document
                .VBComponents(i%).Export ProjectFolder & sName$ & ".bas"
            Else
                ' UNHANDLED/UNKNOWN COMPONENT TYPE
            End If
        Next i
    End With

End Sub

Sub ImportCodeModules()
    Dim i%, sName$

    With ThisWorkbook.VBProject
        ' Iterate all components and attempt to import their source from the network share
        ' Process backwords as we are working through a live array while removing/adding items
        For i% = .VBComponents.count To 1 Step -1
            ' Extract this component name
            sName$ = .VBComponents(i%).CodeModule.Name
            ' Do not change the source of this module which is currently running
            If sName$ <> "VersionControl" Then
                ' Import relevant source file if it exists
                If .VBComponents(i%).Type = 1 Then
                    ' Standard Module
                    .VBComponents.Remove .VBComponents(sName$)

                    ' Import the document. This will come in as a class with an increment suffix (1)
                    Set TempVbComponent = .VBComponents.Import(ProjectFolder & sName$ & ".bas")

                    ' Delete any lines of data in the document
                    If .VBComponents(i%).CodeModule.CountOfLines > 0 Then .VBComponents(i%).CodeModule.DeleteLines 1, .VBComponents(i%).CodeModule.CountOfLines
