How To Capture A Screen Shot From A Webapplication

May 26, 2010

In Java we can do it as follows:

import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
import java.io.File;
...
public void captureScreen(String fileName) throws Exception {
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Rectangle screenRectangle = new Rectangle(screenSize);
Robot robot = new Robot();
BufferedImage image = robot.createScreenCapture(screenRectangle);
ImageIO.write(image, "png", new File(fileName));
}

How do we do this in .NET from a webapplication? Capturing the client's screen and sending it to the server all from within the application.

I'm building a cms and I want users to be able to upload videos but I'm not familiar with video upload & conversion. Is there an example or has anybody coded a solution like this? I heard about ffmpeg but I don't know how to integrate it with asp.net.

As simple solution I can make my clients upload flv files but then I would still need to get a screenshot from that fvl.

Logging To Remote WebPage?

Nov 3, 2010

I wan't to connect to remote web page (that has login form) with HttpWebRequest. I am using this tutorial: http://www.byteblocks.com/page/How-to-submit-requests-to-web-sites-programatically-using-HttpWebRequest.aspx

,but I don't know where RequestAttributes class belongs to?!? Is there any better way to do this? The remote page is in ASP.NET, it's using Form authentication and when someone makes a request to default.aspx it redirects it to login page. I want to parse default.aspx page, but before I am able to do that, I need to pass credentials to login form via POST method in HttpWebRequest. Here is another example using POST method to pass parameters: http://www.worldofasp.net/tut/WebRequest/Working_with_HttpWebRequest_and_HttpWebResponse_in_ASPNET_114.aspx

but I don't understand why this does not work in ASP.NET remote page.

Display Contents In Webpage W/ Width Greater Than Screen Without Displaying Horizontal Scrollbars?

Jun 25, 2010

It'll be hard to explain, but here goes...I have a 3-col table that measures 1200px wide... the middle column measures 800px and includes all the contents, and both remaining rows measure 200px each and have "nice-to-display-but-optional" images (each has a 200px image).On a 1400px display, my table will display with no problems. On the other hand, if the screen is 1000px, then it'll display the scrollbars so it can fit the 1200px of contents.

How can I set the table (or any other html container) so that a 1000px screen only displays what fits on the screen without displaying the scrollbar?In this case, a 1000px would display the middle 800px column, and whatever fits on the sides (half of the 200px images). But the scrollbars would not be displayed, and the images would not be altered so that they fit in the remaining space.

MVC :: Load All Controls In One Shot And Hide It In Backgrund?

May 28, 2010

I am designing SAAS based application on .net MVC 2 platform. Left menu panel, header and footer are common for all pages. I want to avoid loading of these items on every single page. IN a sense I want to use AJAX at application level by refreshing content area ONLY on every click of menu item.

My question:

1)Will this be accomplised by having controls of all virtual web pages on one page and then control their hide and show behaviour depending on menu click? Is there any other better way?

2)What happens when we launch the app? Will it try to load all controls in one shot and hide it in backgrund? OR will it load controls of default page and then fetch what ever is requested via AJAX?

MVC :: Login Page In App Hosted On IIS 7 Integrated Mode - Its Never Getting Redirected To The Home Screen Or Invalid Login Screen

May 19, 2010

I have created my first MVC application. I am using forms authenticataion. I have created a custom action filter MyAppAuthorizationFilter which inherits from AuthorizeFilter. Inside this filter I'm authenticating the user credentials by checking them against a database table (by overriding OnAuthorize method). If the user is not authenticated, I am redirecting the users to a login page (which is view of LoginController). I am using this filter agaginst my main controller so that all actions in this filter will execute only if the user is authenticated.

I do not have any problem when I use the asp.net development server (shipped with Visual Studio). But when I deploy the app to our IIS7 server, I can see the login screen when I access the default url, but after entering the credentials (both correct and incorrect) and posting back the Login page, it stays on the Login page (clears the pwd, but not the username). Its never getting redirected to the home screen or invalid login screen.

IIS 7 server has .net framework 3.5SP1, but no MVC. So I deployed the System.Web.Mvc dll in the bin folder.

Here's my Code (I've omitted the views and models as they are not needed here):

[MyAppAuthorizationFilter]
public class MainController : Controller
{
//
// GET: / [code]......
