Do you want to do this purely from a website or win app as well?

What about the following then?

Hey,

Let us know how you get on with this.

Gary

code was related to webBrowser control....

which i can not use in web...so it's not happening...

any other ideas..?

Why not?

There is absolutely nothing stopping you from doing this.

The WebBrowser is never rendered anywhere, it is used in the Code Behind, simply as a mechanism to obtain the thumbnail.

Did you try to implement the article? If you had, you would have found that this would have worked.

yes i tried but every time it gives me an error that reference is missing..
then i read this webbrowser control is generally used with winforms..

so i thought itis not possible to use in web..

[gep13]

Hey,

It would have given you an error, because you are missing a reference to System.Windows.Form, which is the namespace in which WebBrowser lives.

You are correct when you say that this control is typically used within a Window Application, but in this instance, you are not adding it to a form's surface or anything like that, you are simply creating an instance of it in memory, and then using it to generate the thumbnail.

If I were you, I would be putting the first section of code in that article into a class library, and then you can reference this assembly from your web application.

i'm trying and let u know the output..

[gep13]

Hey,

I have just went through the exercise myself, and it works perfectly.

Gary

[dnanetwork]

yeah works fine but it has image clarity issues..

i mean in 100*100 i can not make out the Thumbnail.

so do u have any idea that i can enhance the image appearance lil higher...

i mean i can not increase the size of image it should be 100 x 100.

[gep13]

Hey,

Not sure on that one off the top of my head, would need to study the code a little closer. What exactly are you doing with these thumbnails, and what sort of clarity are you looking for?

Gary

[dnanetwork]

actually our requirement is something like where user come into my site and
try to search something regarding our product then our code process the search result and filter-outs the urls in our domain and display 100 x 100 image and lil description.

[gep13]

Hey,

Ok, but that doesn't say anything about the clarity of the image, where is this requirement defined? From what you have said above, the code provided does exactly that.
