Here's the start: 1. Add a reference to the COM component first

• Add a reference to Microsoft Internet controls;
• Add a reference to the Microsoft HTML Object Library; (actually mshtml)

2. Create InternetExplorer object, open Browser

The following code snippet jumps to the blog Park login page:

Shdocvw.internetexplorer Obrowser =NewShdocvw.internetexplorer (); ObjectObjflags =1; ObjectObjtargetframename ="_self"; ObjectObjpostdata =""; ObjectObjheaders =""; Obrowser.visible=true; Obrowser.navigate ("Https://passport.cnblogs.com/user/signin",refObjflags,refObjtargetframename,refObjpostdata,refObjheaders);

The first chapter opens the browser, jumps the website The section introduces here, the next chapter introduces uses the Ihtmldocument2,ihtmldocument3 to log in and so on some operation.
