我是Excel VBA和Python的初学者。 尽管python是用于网络抓取的更强大的工具，但我需要使用VBA来做到这一点。
我想在登录网站时获取信息。 我照做，
Dim IE As New SHDocVw.InternetExplorer
IE.Visible = True
IE.navigate "URL(arbitrary)"
Do While IE.Busy Or IE.readyState <> READYSTATE_COMPLETE
Loop
'Next step: Login to website
'In this step, Instead of whole code, I briefly explain.
'Input my ID and PW by .value, and use .click method to login button
'then login is successfully done.
'Next step: then browse IE to desired URL, which contains desired information in that website.
IE.navigate "other URL(arbitrary)"
'My problem is: In this step, IE says that i am not logged on.
我想知道如何保持登录状态。 如果对于初学者来说，这不是一件简单的事情，请告诉我要学习什么以解决VBA中的登录问题。
