我最近在这个论坛的帮助下取得了成功，使用Excel VBA实现了IE的自动化。然而，今天，我遇到了一个新问题，可以使用一些帮助。我试图点击一个超链接，将您带到网站上的新页面。我相信超链接（id =“page2”）包含在iframe中，但我不知道如何访问它。
以下是相关的HTML：
<frame id="workspaceFrame" name="workspaceFrame" frameborder="0" marginheight="0" marginwidth="0" noresize="" src="home.aspx">
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

相关的vba代码如下以及我到目前为止所尝试的以及相应的错误。通过反复试验，我发现我感兴趣的子框架位于：Frames（0）.Frames（0）.Frames（1）.Frames（1）
Dim Window As MSHTML.IHTMLWindow2
Dim button As HTMLInputButtonElement
Dim iFrame As HTMLIFrame
Dim ieApp As SHDocVw.InternetExplorer
Dim ieDoc As MSHTML.HTMLDocument
Dim button As HTMLInputButtonElement
Dim div As HTMLDivElement
' Create a new instance of IE
Set ieApp = New InternetExplorer
' Uncomment this line for debugging purposes.
ieApp.Visible = True
' Go to the page we're interested in.
ieApp.Navigate "MyURL.com"
Do While ieApp.Busy: DoEvents: Loop
Do Until ieApp.ReadyState = READYSTATE_COMPLETE: DoEvents: Loop
Set ieDoc = ieApp.Document
' Try #1
' Error: Automation error
Set Window = ieDoc.Frames(0).Frames(0).Frames(1).Frames(1)
Call Window.execScript("__doPostBack('page2','');", "JavaScript")
' Try #2
' Error: Object variable or With block variable not set
Set button = ieDoc.getElementById("page2")
button.Click
' Try #3
' Error: Automation error
Set Window = ieDoc.Frames(0).Frames(0).Frames(1).Frames(1)("listingframe")
Call Window.execScript("__doPostBack('page2','');", "JavaScript")
对于我可能做错了什么或其他建议的任何想法都将非常感激。
