I am trying to do a screen capture of the entire desktop screen in vb web form .aspx.
I could find the code for form on the internet.
But not for web form.

Is there any guide that i can use to perform a screen capture in vb web form .aspx?

You can't do this and it's no surprise why.

Well, at leat you cannot do this in your ASP.NET code. All of your ASP.NET code runs on the server-side only and generated the HTML that is sent to the browser. The server cannot see the screen of the client machines.

Another problem is that any code running in a users browser runs in a restricted sandbox and cannot get at the machine resources, such as its filesystem, desktop, registry, whatever. This is for security reasons.

Is there a way around this?? Yes. You'd have to write a ActiveX control that the user has to download and install that your web page can call to take the screenshot for you. The problem with this is that not every platform will run an ActiveX control. You'll be limited to Windows machines only. No, I don't have an example.

Now you know why you can't find any ASP.NET code to do this...

To create a screenshot in c# we need to use drawing api of the .net framework

First you have import System.Drawing.Imaging name space with following code...

C#

using System.Drawing.Imaging;

here is the code in C# for screenshot.

C#

 int screenWidth = Screen.GetBounds(new Point(0, 0)).Width;
int screenHeight = Screen.GetBounds(new Point(0, 0)).Height;
Bitmap bmpScreenShot = new Bitmap(screenWidth, screenHeight);
Graphics gfx = Graphics.FromImage((Image)bmpScreenShot);
gfx.CopyFromScreen(0, 0, 0, 0, new Size(screenWidth, screenHeight));
bmpScreenShot.Save("test.jpg", ImageFormat.Jpeg);
