Question

我正在尝试以编程方式在Internet Explorer中配置一些选项，如：

允许ActiveX过滤
允许脚本
等。

它们都存储在注册表中，因此我可以使用。

public void EditKey(String keyPath, String keyName, Int32 newValue)
    {
        using (RegistryKey key = Registry.CurrentUser.OpenSubKey(keyPath, true))
        {
            if (key != null)
                key.SetValue(keyName, newValue, RegistryValueKind.DWord);
        }
    }

这是我的问题：

我需要在工具中添加一个网站 - ＆gt; Internet Explorer中的兼容性视图设置。

经过一番研究，我看到这个网站列表存储在：

HKEY_CURRENT_USER \ Software \ Microsoft \ Internet Explorer \ BrowserEmulation \ ClearableListData \ UserFilter.

问题是这个密钥是二进制密钥所以它有点困难，首先解码其中的内容并进行编辑

我发现每个存储的网站之间都有一个分隔符：

binary key

您清楚地看到网站：123.com和456.com在列表中。我需要在该列表中添加一个网站，但这里可以说这个分隔符似乎随机改变了。

我在我想要的网站上构建了一个预定义的分隔符，所以它看起来像这样：

private void ReadBinaryKey()
    {
        byte[] newWebsite = new byte []
        {
            0x0C,0x00,0x00,0x00,0xA8,0x82,0x8F,0x0D,
            0xC1,0x57,0xCE,0x01,0x01,0x00,0x00,0x00,
            0x08,0x00,0x32,0x00,0x30,0x00,0x32,0x00,
            0x30,0x00,0x2E,0x00,0x6E,0x00,0x65,0x00,
            0x74,0x00
        };

        using (RegistryKey key = Registry.CurrentUser.OpenSubKey(PATH_CVS, true))
        {
            if (key != null)
            {
                var value = (byte[])key.GetValue("UserFilter");

                // need to set my value here key.SetValue("UserFilter", newWebSite)
            }
        }        
    }

我没有尝试过，因为我已经知道它根本不起作用。问题是随机分隔符。还有其他方法可以满足我的需求吗？任何帮助将不胜感激。

感谢。

这是有效的代码。我在Ryoichi Fukushima创建的代码中添加了一些代码。我做的主要区别是我在字节数组中添加了域数。我在IE11，IE10中进行了测试。

Answer 2

也许...

0x00-0x0B : header
0x0C-0x0D : "TOTAL BYTES-12" (UInt16)
0x0E-0x17 : constant A
0x18-0x1B : separator
0x1C-0x23 : UNKNOWN(id? NOT registered datetime...)
0x24-0x27 : constant B
0x28-0x29 : length of target domain(UInt16, ex. example.com is 0x0B,0x00)
0x2A-     : target domain (UNICODE)
[repeat separator...target domain]

Answer 3

以下是我阅读此数据的方法：

Bytes  Description
00-07  Header (Appears to be constant "41,1f,00,00,53,08,ad,ba")
08-11  Int64 Total # of entries in the list
12-15  Int64 Total # of bytes to follow including this number. (DataLen + 4)
16-19  Int64 Version (seems to always be 1)
20-??  Repeating entries.

Entry Format
Bytes  Description
00-03  Int64   Entry Number  (Increments for each entry)
04-07  Int64   Entry Header (Seems to be constant at 12 (0xC))
08-11  Int64   Unknown - Checksum?
12-15  Int64   Unknown - Timestamp?
16-19  Int64   Unknown - Always 1
20-21  Int32   Length of data to follow  (an entry of abc.com would be 7)
22-??  Unicode Chars for the website/address
