c++ - C++, web browser control: cannot change encoding/charset

Question

There's a document I'm displaying in a web browser ActiveX control hosted in a C++ app. This document has a META tag that specifies incorrect charset, so the output is funny. I know the correct encoding and want to change it programmatically to fix that. But whatever I try, the encoding remains unchanged.

I alredy tried, in various combinations and flavors:

• IHTMLDocument2::put_Charset (after the document finished loading);
• changing the "charset" property of the "META" tag (using IHTMLMetaElement);
• deleting the "META" tag altogether (by setting its "outerHTML" to empty string);
• refreshing the control.

The control demonstrates remarkable persistence in preserving the incorrect encoding. What are my other options? I can't manipulate the source of the document being loaded.

Answer 1

尝试把designMode属性"On"。

Answer 2

以下是最终奏效的方法：

在“NavigateComplete2”浏览器事件的处理程序中，

• 使用 charset 属性修改字符集，
• 然后通过将其 outerHTML 设置为空字符串来丢弃 META 标签，
• 然后刷新控件。

修改这些动作的顺序，或者省略一个步骤，都会导致整个操作无效。MSHTML 很挑剔。

Answer 3

据此，如果IWebBrowser->Refresh()您在调用后调用它应该可以工作IHTMLDocument2->put_charset()。
