Question

在VBA或C＃代码中，有没有办法获取工作簿中定义的现有宏的列表？

理想情况下，此列表会有一个方法定义签名，但只是获取可用宏的列表会很棒。

这可能吗？

Answer 1

我很长时间没有为Excel做过vba，但是如果我记得很清楚，代码的对象模型是通过脚本无法访问的。

当您尝试访问它时，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了，您可以使用vba / c＃导出模块并在其中进行文本搜索，使用正则表达式查找子声明和函数声明，然后删除导出的模块。

我不确定是否还有其他方法可以做到这一点，但这应该有用。

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

这是我获取有关提供对VB IDE的强制访问的信息。

基于Martin的回答，在您信任访问VBP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。你可以修改它只包括subs，或只是funcs，或者只是私有或只是公开......

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
                End If
            End If
        Next i
    Next VBComp
 PROC_END:
    Exit Function
 PROC_ERR:
    GoTo PROC_END
End Function

Private Function RemoveCharFromLeftOfString(TheString As String, RemoveChar As String) As String
    Dim Result As String
    Result = TheString
    While LCase(Left(Result, Len(RemoveChar))) = LCase(RemoveChar)
        Result = Right(Result, Len(Result) - Len(RemoveChar))
    Wend
    RemoveCharFromLeftOfString = Result
End Function

Private Function RemoveBlanksAndDecsFromSubDec(TheLine As String) As String
    Dim Result As String
    Result = TheLine
    Result = RemoveCharFromLeftOfString(Result, " ")
    Result = RemoveCharFromLeftOfString(Result, "   ")
    Result = RemoveCharFromLeftOfString(Result, "Public ")
    Result = RemoveCharFromLeftOfString(Result, "Private ")
    Result = RemoveCharFromLeftOfString(Result, " ")
    RemoveBlanksAndDecsFromSubDec = Result
End Function

Private Function RemoveAsVariant(TheLine As String) As String
    Dim Result As String
    Result = TheLine
    Result = Replace(Result, "As Variant", "")
    Result = Replace(Result, "As String", "")
    Result = Replace(Result, "Function", "")
    If InStr(1, Result, "( ") = 0 Then
        Result = Replace(Result, "(", "( ")
    End If
    RemoveAsVariant = Result
End Function

Private Function IsSubroutineDeclaration(TheLine As String) As Boolean
    If LCase(Left(RemoveBlanksAndDecsFromSubDec(TheLine), Len("Function "))) = "function " Or LCase(Left(RemoveBlanksAndDecsFromSubDec(TheLine), Len("sub "))) = "sub " Then
        IsSubroutineDeclaration = True
    End If
End Function

Private Function GetSubName(DecLine As String) As String
    GetSubName = FindToRightOfString(FindToLeftOfString(DecLine, "("), " ")
End Function

Function FindToLeftOfString(FullString As String, ToFind As String) As String
    If FullString = "" Then Exit Function
    Dim Result As String, ToFindPos As Integer
    ToFindPos = InStr(1, FullString, ToFind, vbTextCompare)
    If ToFindPos > 0 Then
        Result = Left(FullString, ToFindPos - 1)
    Else
        Result = FullString
    End If
    FindToLeftOfString = Result
End Function

Function FindToRightOfString(FullString As String, ToFind As String) As String
    If FullString = "" Then Exit Function
    Dim Result As String, ToFindPos As Integer
    ToFindPos = InStr(1, FullString, ToFind, vbTextCompare)
    Result = Right(FullString, Len(FullString) - ToFindPos + 1 - Len(ToFind))
    If ToFindPos > 0 Then
        FindToRightOfString = Result
    Else
        FindToRightOfString = FullString
    End If
End Function
