Question

我正在尝试获取它，以便在打开工作簿时，它会联机检查一个文件夹，然后，如果VBA文件已更新，它将覆盖工作簿中的旧文件夹。在此文件夹中将有4个.bas文件。有办法吗？

Answer 1

您可以执行此操作，但前提是已授予“对VBA项目对象模块的信任访问权限”。您可以在Excel选项>信任中心>宏设置下找到此设置。

由于这是在每个单独的excel安装上设置的设置，因此只有在确定可以激活此设置的情况下，才可以这样做。否则，您编写的任何代码都会失败。

Answer 2

我很久以前可能在这里或其他网站上找到了此代码。如上一个答案所述，您需要激活该选项才能起作用。

您需要两个模块

导入模块：

Option Explicit
Public Sub ImportModules()
    Dim wkbTarget As Excel.Workbook
    Dim objFSO As Scripting.FileSystemObject
    Dim objFile As Scripting.File
    Dim szTargetWorkbook As String
    Dim szImportPath As String
    Dim szFileName As String
    Dim cmpComponents As VBIDE.VBComponents
'
'    If ActiveWorkbook.Name = ThisWorkbook.Name Then
'        MsgBox "Select another destination workbook" & _
'        "Not possible to import in this workbook "
'        Exit Sub
'    End If

    'Get the path to the folder with modules
    If FolderWithVBAProjectFiles = "Error" Then
        MsgBox "Import Folder not exist"
        Exit Sub
    End If

    ''' NOTE: This workbook must be open in Excel.
    szTargetWorkbook = ActiveWorkbook.Name
    Set wkbTarget = Application.Workbooks(szTargetWorkbook)

    If wkbTarget.VBProject.Protection = 1 Then
    MsgBox "The VBA in this workbook is protected," & _
        "not possible to Import the code"
    Exit Sub
    End If

    ''' NOTE: Path where the code modules are located.
    szImportPath = FolderWithVBAProjectFiles & "\"

    Set objFSO = New Scripting.FileSystemObject
    If objFSO.GetFolder(szImportPath).Files.Count = 0 Then
       MsgBox "There are no files to import"
       Exit Sub
    End If

    'Delete all modules/Userforms from the ActiveWorkbook
    Call DeleteVBAModulesAndUserForms

    Set cmpComponents = wkbTarget.VBProject.VBComponents

    ''' Import all the code modules in the specified path
    ''' to the ActiveWorkbook.
    For Each objFile In objFSO.GetFolder(szImportPath).Files
        If objFile.Name Like "*Modulos*" Then GoTo Siguiente 'here to skip modules which name contain "Modulos"
        If (objFSO.GetExtensionName(objFile.Name) = "cls") Or _
            (objFSO.GetExtensionName(objFile.Name) = "frm") Or _
            (objFSO.GetExtensionName(objFile.Name) = "bas") Then
            cmpComponents.Import objFile.Path
        End If
Siguiente:
    Next objFile

    MsgBox "Módulos actualizados"
End Sub

导出模块：

Option Explicit
Public Sub ExportModules()
    Dim bExport As Boolean
    Dim wkbSource As Excel.Workbook
    Dim szSourceWorkbook As String
    Dim szExportPath As String
    Dim szFileName As String
    Dim cmpComponent As VBIDE.VBComponent

    ''' The code modules will be exported in a folder named.
    ''' VBAProjectFiles in the Documents folder.
    ''' The code below create this folder if it not exist
    ''' or delete all files in the folder if it exist.
    If FolderWithVBAProjectFiles = "Error" Then
        MsgBox "Export Folder not exist"
        Exit Sub
    End If

    On Error Resume Next
        Kill FolderWithVBAProjectFiles & "\*.*"
    On Error GoTo 0

    ''' NOTE: This workbook must be open in Excel.
    szSourceWorkbook = ActiveWorkbook.Name
    Set wkbSource = Application.Workbooks(szSourceWorkbook)

    If wkbSource.VBProject.Protection = 1 Then
    MsgBox "The VBA in this workbook is protected," & _
        "not possible to export the code"
    Exit Sub
    End If

    szExportPath = FolderWithVBAProjectFiles & "\"

    For Each cmpComponent In wkbSource.VBProject.VBComponents

        bExport = True
        szFileName = cmpComponent.Name

        ''' Concatenate the correct filename for export.
        Select Case cmpComponent.Type
            Case vbext_ct_ClassModule
                szFileName = szFileName & ".cls"
            Case vbext_ct_MSForm
                szFileName = szFileName & ".frm"
            Case vbext_ct_StdModule
                szFileName = szFileName & ".bas"
            Case vbext_ct_Document
                ''' This is a worksheet or workbook object.
                ''' Don't try to export.
                bExport = False
        End Select
        If bExport Then
            ''' Export the component to a text file.
            cmpComponent.Export szExportPath & szFileName
        ''' remove it from the project if you want
        '''wkbSource.VBProject.VBComponents.Remove cmpComponent
        End If
    Next cmpComponent
    MsgBox "Export is ready"

End Sub
Function FolderWithVBAProjectFiles() As String
    Dim WshShell As Object
    Dim FSO As Object
    Dim SpecialPath As String

    Set WshShell = CreateObject("WScript.Shell")
    Set FSO = CreateObject("scripting.filesystemobject")

    SpecialPath = "Z:\Planificacion-WFM\Planificacion Telefonica\Código"

    If Right(SpecialPath, 1) <> "\" Then
        SpecialPath = SpecialPath & "\"
    End If

    If FSO.FolderExists(SpecialPath & "VBAProjectFiles") = False Then
        On Error Resume Next
        MkDir SpecialPath & "VBAProjectFiles"
        On Error GoTo 0
    End If

    If FSO.FolderExists(SpecialPath & "VBAProjectFiles") = True Then
        FolderWithVBAProjectFiles = SpecialPath & "VBAProjectFiles"
    Else
        FolderWithVBAProjectFiles = "Error"
    End If

End Function
Function DeleteVBAModulesAndUserForms()
        Dim VBProj As VBIDE.VBProject
        Dim VBComp As VBIDE.VBComponent

        Set VBProj = ActiveWorkbook.VBProject

        For Each VBComp In VBProj.VBComponents
            If VBComp.Type = vbext_ct_Document Then
                'Thisworkbook or worksheet module
                'We do nothing
            ElseIf Not VBComp.Name Like "*Modulos*" Then 'ignore modules which name contain "Modulos"
                VBProj.VBComponents.Remove VBComp
            End If
        Next VBComp
End Function

有没有办法在打开的工作簿上导入VBA模块？
