vba - 如何获取 Excel 工作簿中定义的宏

Question

有没有办法在 VBA 或 C# 代码中获取工作簿中定义的现有宏的列表？

理想情况下，这个列表应该有一个方法定义签名，但是仅仅得到一个可用宏的列表就很好了。

这可能吗？

Answer 1

我很久没有为 Excel 做 vba，但如果我记得清楚的话，代码的对象模型是无法通过脚本访问的。

当您尝试访问它时，您会收到以下错误。

Run-time error '1004':
Programmatic access to Visual Basic Project is not trusted

尝试：

Tools | Macro | Security |Trusted Publisher Tab
[x] Trust access to Visual Basic Project

现在您可以访问 VB IDE，您可能可以导出模块并在其中进行文本搜索，使用 vba / c#，使用正则表达式查找子和函数声明，然后删除导出的模块。

我不确定是否有其他方法可以做到这一点，但这应该可以。

您可以查看以下链接，开始导出模块。 http://www.developersdex.com/vb/message.asp?p=2677&ID=%3C4FCD0AE9-5DCB-4A96-8B3C-F19C63CD3635%40microsoft.com%3E

在这里，我获得了有关提供对 VB IDE 的推力访问的信息。

基于 Martin 的回答，在您信任对 VBP 的访问之后，您可以使用这组代码来获取 Excel 工作簿的 VB 项目中所有公共子例程的数组。您可以将其修改为仅包含 subs，或仅包含 func，或仅包含私有或仅包含公共...

Private Sub TryGetArrayOfDecs()
    Dim Decs() As String
    DumpProcedureDecsToArray Decs
End Sub

Public Function DumpProcedureDecsToArray(ByRef Result() As String, Optional InDoc As Excel.Workbook) As Boolean
    Dim VBProj As Object
    Dim VBComp As Object
    Dim VBMod As Object

    If InDoc Is Nothing Then Set InDoc = ThisWorkbook

    ReDim Result(1 To 1500, 1 To 4)
   DumpProcedureDecsToArray = True
    On Error GoTo PROC_ERR

    Set VBProj = InDoc.VBProject
    Dim FuncNum As Long
    Dim FuncDec As String
    For Each VBComp In VBProj.vbcomponents
        Set VBMod = VBComp.CodeModule
        For i = 1 To VBMod.countoflines
            If IsSubroutineDeclaration(VBMod.Lines(i, 1)) Then
                FuncDec = RemoveBlanksAndDecsFromSubDec(RemoveAsVariant(VBMod.Lines(i, 1)))
                If LCase(Left(VBMod.Lines(i, 1), Len("private"))) <> "private" Then
                    FuncNum = FuncNum + 1
                    Result(FuncNum, 1) = FindToLeftOfString(InDoc.Name, ".")    '
                    Result(FuncNum, 2) = VBMod.Name
                    Result(FuncNum, 3) = GetSubName(FuncDec)
                    Result(FuncNum, 4) = VBProj.Name
