Get word from Web browser control on mouse hover event

Nageswararao Dhulipalla

Hi,

In webbrowser control I am binding (Navigate) the html file.
When mouse over of any word I want to retrieve that particular word.
When Mouse Hover event I want to get the specific word where the mouse position on the Webbrowser document.
Is there any direct way to do this.

It's very urgent.

Thank's in Advanced.

That other thread solution is working fine for small documents. But for the large document performance issue is coming which our application makes problem.

Thus why finding different solution which consider performance issue also.

This question was asked about a month ago in a different thread and there was very much work put into solving the problem. You really must look at that thread. I think however that it was not successful; there was not a good solution found. I am sure there is a solution but I don't know what it is and it is not easy to find.

Hi,

Please find the attachment sample code.
After load the form click on play button, then click on pause button.
Mouse over on Highlight sentance the mouse hover functionality is not working.
This is the requirement.
And this is simple text and for html file the display content is changing to html tags and I clickon play and mouse hover.

Hi,

Thanks for the quick reply. This will work for small files but for big files it will give preformance issue.

Please find the html files(priority s20210fulltext.html) which I am getting the problem.

Try this create a H1 tag in your HTML file and hover the mouse on that you can see the text placed in text box

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication1
{
public partial class Form5 : Form
{
public Form5()
{
InitializeComponent();
webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBrowser1_DocumentCompleted);
}

void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
webBrowser1.Document.Body.MouseOver += new HtmlElementEventHandler(Body_MouseOver);
}

void Body_MouseOver(object sender, HtmlElementEventArgs e)
{
if (e.ToElement != null && e.ToElement.TagName == "H1" && e.ToElement.GetAttribute("processed") != "true")
{
string[] words = e.ToElement.InnerHtml.Split(' ');
e.ToElement.InnerHtml = "";
for (int i = 0; i < words.Length; i++)
e.ToElement.InnerHtml += " " + words[i] + " ";

foreach (HtmlElement el in e.ToElement.GetElementsByTagName("span"))
el.MouseOver += new HtmlElementEventHandler(e_MouseOver);

e.ToElement.SetAttribute("processed", "true");
}
}

void e_MouseOver(object sender, HtmlElementEventArgs e)
{
toolStripTextBox1.Text = e.ToElement.InnerText;
}

}
}
