功能描述

为了方便备份代码，运行一个函数，导出类、模块、窗体。当在其他vba工程使用时，可以运行另外一个函数，快速导入代码。

1、开发人员宏设置：信任对VBA工程对象模型的访问

2、引用 Microsoft Visual Basic for Applications Extensibility

3、代码

Option Explicit

' 导出模块、类模块和用户窗体
Sub ExportModulesClassesAndForms()

    Dim vbComp As VBComponent
    Dim FilePath As String
    Dim BackupFolder As String

    ' 设置备份文件夹名称
    BackupFolder = ThisWorkbook.Path & "\backcode\"

    ' 检查备份文件夹是否存在，如果不存在则创建
    If Len(Dir(BackupFolder, vbDirectory)) = 0 Then
        MkDir BackupFolder
    End If

    ' 设置文件保存路径
    FilePath = BackupFolder

    ' 遍历所有 VB 组件
    For Each vbComp In ThisWorkbook.VBProject.VBComponents
        Select Case vbComp.Type
            Case vbext_ct_StdModule
                vbComp.Export FilePath & vbComp.Name & ".bas"
