WPF WebBrowser Control-critical code

1. Gets the value of the element, based on the element ID.

For example to get This the value of the SRC attribute in the tag:

Mshtml. IHTMLDocument2 doc2 = (mshtml. IHTMLDocument2) webbrowser1.document; Mshtml. IHTMLElement img = (mshtml. IHTMLElement) Doc2.all.item ("Regimg", 0);

String imgurl = (string) img.getattribute ("src");

2. Fill out the form and determine

Mshtml. IHTMLElement LoginName = (mshtml.     IHTMLElement) Doc2.all.item ("LoginName", 0); Mshtml. IHTMLElement LOGINPW = (mshtml.     IHTMLElement) Doc2.all.item ("password", 0); Mshtml. IHTMLElement LOGINBT = (mshtml.     IHTMLElement) Doc2.all.item ("Formsubmit", 0); Mshtml. IHTMLElement Loginyz = (mshtml.     IHTMLElement) Doc2.all.item ("Regcode", 0); Loginname.setattribute ("value", tbloginname.text);
Loginpw.setattribute ("value", Tbloginpassword.password);
Loginyz.setattribute ("value", tbyz.text);
Loginbt.click ();

3. Get the source code

TextBox1.Text = Doc2.body.innerHTML;

4. Execute JS

Mshtml. IHTMLWindow2 win = (mshtml. IHTMLWINDOW2) Doc2.parentwindow;
Win.execscript ("changeregimg ()", "JavaScript");//Use JS

5, prohibit JS,WPF under the current discovery only applicable one method:

public void Hidescripterrors (WebBrowser WB, BOOL Hide)
{
FieldInfo Ficomwebbrowser = typeof (WebBrowser). GetField ("_axiwebbrowser2", BindingFlags.Instance | BindingFlags.NonPublic);

if (Ficomwebbrowser = = null) return;

Object objcomwebbrowser = Ficomwebbrowser.getvalue (WB);

if (Objcomwebbrowser = = null) return;

Objcomwebbrowser.gettype (). InvokeMember ("Silent", BindingFlags.SetProperty, Null,objcomwebbrowser, new object[] {Hide});

}

void Webbrowser1_navigated (object sender, NavigationEventArgs e)
{

Hidescripterrors (WebBrowser1, true);

}
