How to make progress bar sync with page load (C #)? ?

datoumao

Recently made a browser

I want to make a progress bar like the bottom left corner of IE and other browsers, but I don't know how to associate the progressbar with my webbrowser to achieve the purpose of synchronizing the page loading and the progress bar.

Please say more in detail ~~ Thank you all in advance ~

Establish a delegation:
   _axWebBrowser.ProgressChange + = new
                AxSHDocVw.DWebBrowserEvents2_ProgressChangeEventHandler (
                this.mainBrowser_ProgressChange);
Reprocessing:
     private void mainBrowser_ProgressChange (object sender, AxSHDocVw.DWebBrowserEvents2_ProgressChangeEvent e)
        {// Handle progress bar events
            AxSHDocVw.AxWebBrowser axWebBrowser1 = (AxSHDocVw.AxWebBrowser) sender;
            HE_WebBrowserTag _HE_WebBrowserTag = (HE_WebBrowserTag) axWebBrowser1.Tag;

            // If the current page does not match the current webbrowser, then discard it
            if (_HE_WebBrowserTag._TabIndex! = this.MainTabCtrl.SelectedIndex) {return;}

            processBar.Visible = true;
            if ((e.progress> 0)&&(e.progressMax> 0))
            {
                processBar.Maximum = e.progressMax;
                processBar.Step = e.progress;
                processBar.PerformStep ();
            }
            else if (axWebBrowser1.ReadyState == SHDocVw.tagREADYSTATE.READYSTATE_COMPLETE)
            {
                processBar.Value = 0;
                processBar.Visible = false;
            }
        }

Good, I even try it first.

Can you explain the principle

Still don't quite understand ~

This is equivalent to trying to reference the browser's wait function

VS2005 uses webBrowser code:
private void Form1_Load (object sender, EventArgs e)
        {
            Uri url = new Uri ("http://www.163.com");
            webBrowser1.Url = url;
            webBrowser1.ProgressChanged + = new WebBrowserProgressChangedEventHandler (webBrowser1_ProgressChanged);
        }

        private void webBrowser1_ProgressChanged (object sender, WebBrowserProgressChangedEventArgs e)
        {
            
            processBar.Visible = true;
            if ((e.CurrentProgress> 0)&&(e.MaximumProgress> 0))
            {
                processBar.Maximum = Convert.ToInt32 (e.MaximumProgress);
                processBar.Step = Convert.ToInt32 (e.CurrentProgress);
                processBar.PerformStep ();
            }
            else if (webBrowser1.ReadyState == WebBrowserReadyState.Complete)
            {
                processBar.Value = 0;
                processBar.Visible = false;
            }
        }

Can you talk about his specific implementation process ~
There are many details that are not well understood ~~

Jack it up yourself!
