Step 1. Make a new class which will hold all neccessary things to capture the thumbnail

public class WebsiteThumbnailImageGenerator
{
public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight)
{
WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight);
return thumbnailGenerator.GenerateWebSiteThumbnailImage();
}

private class WebsiteThumbnailImage
{
public WebsiteThumbnailImage(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight)
{
this.m_Url = Url;
this.m_BrowserWidth = BrowserWidth;
this.m_BrowserHeight = BrowserHeight;
this.m_ThumbnailHeight = ThumbnailHeight;
this.m_ThumbnailWidth = ThumbnailWidth;
}

private string m_Url = null;
public string Url
{
get
{
return m_Url;
}
set
{
m_Url = value;
}
}

private Bitmap m_Bitmap = null;
public Bitmap ThumbnailImage
{
get
{
return m_Bitmap;
}
}

private int m_ThumbnailWidth;
public int ThumbnailWidth
{
get
{
return m_ThumbnailWidth;
}
set
{
m_ThumbnailWidth = value;
}
}

private int m_ThumbnailHeight;
public int ThumbnailHeight
{
get
{
return m_ThumbnailHeight;
}
set
{
m_ThumbnailHeight = value;
}
}

private int m_BrowserWidth;
public int BrowserWidth
{
get
{
return m_BrowserWidth;
}
set
{
m_BrowserWidth = value;
}
}

private int m_BrowserHeight;
public int BrowserHeight
{
get
{
return m_BrowserHeight;
}
set
{
m_BrowserHeight = value;
}
}

public Bitmap GenerateWebSiteThumbnailImage()
{
Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage));
m_thread.SetApartmentState(ApartmentState.STA);
m_thread.Start();
m_thread.Join();
return m_Bitmap;
}

private void _GenerateWebSiteThumbnailImage()
{
WebBrowser m_WebBrowser = new WebBrowser();
m_WebBrowser.ScrollBarsEnabled = false;
m_WebBrowser.Navigate(m_Url);
m_WebBrowser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(WebBrowser_DocumentCompleted);
while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete)
Application.DoEvents();
m_WebBrowser.Dispose();
}

private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
WebBrowser m_WebBrowser = (WebBrowser)sender;
m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight);
m_WebBrowser.ScrollBarsEnabled = false;
m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height);
m_WebBrowser.BringToFront();
m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds);
m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero);
}
}
}

Step 2: Call the GetWebSiteThumbnail() function of class like this

string address = www.google.com;

int width  = 200;

int height = 140;

int capWidth = 800;

int capHeight = 600;

Bitmap thumbnail = WebsiteThumbnailImageGenerator.GetWebSiteThumbnail(address, capWidth, capHeight, width, height);

Step 3 : Save the image to particular place of your website.

thumbnail.Save(Server.MapPath(“FolderName\\”) + “MyImageName”,ImageFormat.Jpeg);

Now you can find a jpeg image on your desired location.

Optional enhancement:

You can also directly give it on your aspx page like

On Step 3: thumbnail.Save (Response.OutputStream, ImageFormat.Jpeg);

<asp:Image ID=”Image1″ ImageUrl=”snapshot.aspx?site=www.google.com&width=100&height=80&capWidth=800&capHeight=600″ runat=”server” />

and on this image place you will have image.

In order to work exactly same in both IE6 and IE7. just add

overflow:hidden

and it is done.

btnViewed.Style["font-weight"] = “bold”;

Hopefully it will help.

You have to first find the repeater and then you can do all the things with it as you do in normal .

Control myControl = TabContainer1.Tabs[0].FindControl(“RepeaterName”);

Repeater MyRepeater = (Repeater)myControl;

or simply in single step

Repeater MyRepeater =(Repeater)TabContainer1.Tabs[0].FindControl(“RepeaterName“);

Now you can bind data with it or do any operation with this repeater.

Hopefully it will help, if find helpful please leave a comment

If you do not want to add your JavaScript files declaratively via HTML to your ASP.Net page, you can do it in code, and here is how:

Just add this code to the Page_Init event handler on your page:

protected void Page_Init(object sender, EventArgs e)

{

HtmlGenericControl js = new HtmlGenericControl(“script”);

js.Attributes["type"] = “text/javascript”;

js.Attributes["src"] = “jscript/formfunctions.js”;

Page.Header.Controls.Add(js);

}

And thats all there is to it .

Following is the way

protected void Page_Init(object sender, EventArgs e)

{

HtmlLink css = new HtmlLink();

css.Href = “css/fancyforms.css”;

css.Attributes["rel"] = “stylesheet”;

css.Attributes["type"] = “text/css”;

css.Attributes["media"] = “all”;

Page.Header.Controls.Add(css);

}

And thats it, next time you load this page, reference to your CSS file will be added at runtime to the page HTML code and loaded.

1. Retrieve the id video from the link (the code after ‘v=’)
example: http://www.youtube.com/watch?v=NegsNQy1ZoU => NegsNQy1ZoU
2. In your favourite browser go to http://youtube.com/v/{ID video}
example: http://youtube.com/v/NegsNQy1ZoU
3. Link in the address bar will change. Replace ’swf/l.swf’ with ‘get_video’ and press Enter
4. Save your file

Just experienc it in your browser.

Do It Progrmatically:

Now we will do it programaticaly using asp.net. Just follow followin steps

1. Create a page named as DownloadUTube.aspx

<body>
<form id=”form1″ runat=”server”>
<div>
<table>
<tr>
<td>YouTube URL: <asp:TextBox ID=”txtUrl” runat=”server”></asp:TextBox></td>
<td><asp:Button ID=”btnSubmit” runat=”server” Text=”Submit” OnClick=”btnSubmit_Click” /></td>
</tr>
<tr>
<td align=”center” colspan=”2″>Example: http://www.youtube.com/watch?v=NegsNQy1ZoU </td>
</tr>
<tr>
<td colspan=”2″><asp:Literal ID=”litResult” runat=”server”></asp:Literal></td>
</tr>
</table>
</div>
</form>
</body>

You have successfully completed 1st step now proceed to 2nd one.

Step 2:

Now in your cSharp file you have to go as follow.

// First of all we will change our utube link to our desired format.

string URL = this.txtUrl.Text;
string VideoId = URL.Substring(URL.IndexOf(‘=’)+1);
URL = @”http://youtube.com/v/” + VideoId;

// Now we will send request to server which will create new link.
WebRequest MyRequest = HttpWebRequest.Create(URL);
WebResponse MyResponse = MyRequest.GetResponse();

// we get newly create link into string RealURL
string RealURL = MyResponse.ResponseUri.ToString();

// Creates an HttpWebRequest with the specified URL.
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(RealURL);

// Sends the HttpWebRequest and waits for the response.
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

// Gets the stream associated with the response.
Stream receiveStream = myHttpWebResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding(“utf-8″);

// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader(receiveStream, encode);

// Now we will write whole stream to specified. It is the path within your website.
StreamWriter writer = new StreamWriter(Server.MapPath(@”Contents\Videos\YourVideoName.flv”), true);
writer.Write(readStream.ReadToEnd());
writer.Close();

Just go on specified path and u will see the video.

Final saying, if you have any problem about this. write to me. I will try my best to solve it.

It is because of the fact that firefox caches the form fields. Two ways to encounter this problem.

1.Write following snipet in your cs file

protected override void OnPreInit(EventArgs e)
{
base.OnPreInit(e);
if (Request.Browser.MSDomVersion.Major == 0) // If it is Non IE Browser
{
Response.Cache.SetNoStore();
}
}

2. In page load, write following statemet

Response.Cache.SetNoStore();

Now error has been removed and you can sleep with satisfaction.

For example, you can grab the contents of stock exchange site and then extract useful information from that one. We will remain at very basic level in this article. In future we will move to some useful practical knowledge.

Scraping through ASP.NET:

You have to include following name spaces

1. System.Net (For WebClient)      2. System.Text (For UTF8Encoding)

// make object of WebClient.

WebClient MyClient = new WebClient();

// the url of site whose contents you want to grab.
string Url = “http://www.google.com.pk”

// to get string, as downloaded data returns byte[]
UTF8Encoding MyEncoding = new UTF8Encoding();

// Calling DownloadData function. It will return all contents inform of byte[] array. You can get the                    string by calling GetString method of UTF8Encoding object
string str = MyEncoding.GetString(MyClient.DownloadData(Url));

In this string you have all the contents. you can extract any thing from it.

Enjoy.
