获取InternetExplorer对象的ReadyState时出现自动化错误 [英] Automation error when getting ReadyState of InternetExplorer object

问题描述

我在同一行上遇到两个不同的错误.有时候这个:

I get two different errors on the same line. Sometimes this one:

自动化错误:调用的对象已与其客户端断开连接

Automation error: object invoked has disconnected from its clients

有时:

界面未知

重现错误的最小代码:

Sub mcve()
    Dim ie As Object
    Dim www As String
    Set ie = New InternetExplorerMedium
    www = "http://www.stackoverflow.com"
    ie.navigate www
    ie.Visible = False
    While ie.ReadyState <> 4    ' <~~~~~~~~~~~~~~~~~~~~~~~~ Error occurs here
        DoEvents
    Wend
End Sub

这需要参考:工具">参考...">"Microsoft Internet控件"

This requires a reference: Tools > References... > Microsoft Internet Controls

该错误第二次出现在While ie.ReadyState <> 4上.我该如何解决?

The error occurs on While ie.ReadyState <> 4 the second time. How do I fix this?

推荐答案

这是

This is a duplicate of a previously asked question. The problem seems to be caused by Internet Explorer security settings - when switching between security zones, the current instance of IE is killed and a new instance is created, so your reference to the old process is no longer valid.

一些建议的解决方案是:

Some of the suggested solutions were:

1. 更改IE安全设置.取消选中"Internet选项"的安全"选项卡上的启用保护模式".
2. 直接导航到IP地址而不是URL.这是为我修复的.例如，ie.navigate "64.233.177.106"(Google的IP地址)
3. Set ie = New InternetExplorerMedium而不是New InternetExplorer.反之亦然.

1. Change IE security settings. Uncheck "enable protected mode" on the Security tab of Internet Options.
2. Navigate to the IP address directly instead of the URL. This is the one that fixed it for me. For example, ie.navigate "64.233.177.106" (Google's IP address)
3. Set ie = New InternetExplorerMedium instead of New InternetExplorer. Or in your case, vice versa.
