    Dim VBComp
    Dim CodeMod
    Dim LineNum As Long
    Dim ProcKind
   
    For Each VBComp In wb.VBProject.VBComponents
        If VBComp.Name = "模块1" Then
       
            With VBComp.CodeModule
           
                For N = 1 To .CountOfLines
                    s = .Lines(N, 1)
                    If InStr(s, Proc) > 0 Then
                        FindProcedures = True
                        Exit Function
                    End If
