我试图以这种方式使用IHTMLDocument2界面更改div的内容:
IHTMLElementCollection* collection = NULL;
IDispatch* mydiv;
doc2->get_all(&collection);
long count;
collection->get_length(&count); //just to check I get something
CComVariant varstr = L"mydivname";
CComVariant varint = 0;
collection->item(varstr, varint, &mydiv); //this works I get the div
IHTMLElement* htmldiv;
mydiv->QueryInterface(IID_IHTMLElement, (void**)&htmldiv);
CComBSTR html;
htmldiv->get_innerHTML(&html); //works too, I get the current content
HRESULT hr=htmldiv->put_innerText(L"hello"); //this does not work but returns S_OK
collection->Release();
所以我的div的内容刚刚被删除,而不是用"你好",我不明白为什么,这可能是一个安全问题吗?

根据MSDN documentation,传递给put_innerText
的字符串属于BSTR
类型。
所以,我建议尝试这样的代码:
CComBSTR text(OLESTR("hello"));
hr = htmldiv->put_innerText(text);
