我还没有试过,但我想加载一个带有
file://...
而不是http://...
将起作用。使用Navigate或Navigate2方法之一
要访问联机页面,请执行以下操作:
pHtmlView->Navigate("http://www.google.com");
要访问本地HTML文件,请执行以下操作:
pHtmlView->Navigate("c:\\mypath\\myfile.html");
根据您的实现,HTML控件可能需要COM类型的访问,或者如果您需要设置附加信息(如标题),则
CString strHeader = "User Agent:Mozilla/5.0...";
m_browserCtrl.Navigate2(&_variant_t(_T("file://C:\\mypath\\myfile.htm")), NULL, NULL, NULL, &_variant_t(_T(strHeader)));
