About the use of the MFC WebBrowser plug-in

Recently wrote things often need to embed some browsers, Microsoft provides a better interface, can be embedded in MFC program in a simple browser, is the form of an ActiveX plug-in to provide the interface, the use of more convenient, here I will simply record the use of this plugin

Here I use VC6 for example, my machine is too rotten to run vs this giant-level software.

First, create a dialog box and right-click on the plugin to insert ActiveX into the dialog.

You can see that Microsoft offers a lot of ActiveX plugins for us to choose from.

When the browser plugin is selected to be able to see a browser's ActiveX plugin, let's associate a variable m_test

When you are connected, fill in a message response at the OK button.

M_test. Navigate ("www.baidu.com", null,null,null,null);

Use a member function of this variable to open this URL

A few questions about WebBrowser

Write (Strcookie,strcookie.getlength ()); myfile. Close ();//::messagebox (NULL, Strcookie, "current Cookie", mb_iconinformation);  } Lpdocument2->put_cookie (NULL);p body->release ();        Lpdocument2->release ();    }    Lpdispatch->release ();
