主题：[求助]这段代码是什么意思，请赐教

baseMainform.SuspendLayout

Dim tbp As WinForm.TopicBar = e.Form.Controls("TopicBar1")

For Each pg As WinForm.TopicPage In tbp.Pages

    For Each lnk As WinForm.TopicLink In pg.Links

        lnk.Text = lnk.Text.Trim("←")

    Next

Next

e.Link.Text = e.Link.Text & "←"

MarkCell = False

For Each frm As Winform.Form In Forms

    If frm.Opened AndAlso frm.FormStyle = FormStyleEnum.独立 Then

        frm.Close()

    End If

Next

能将每段代码的意思解释一下吗？
