ASP.NET/ActiveX/Silverlight Screen Capture

Question

I need a way to capture a screen in a web application in any way. Is there such a way without installing other tools like SnagIt? Can I use Win32 DllImports in an ActiveX component and do it this way?

Thanks in advance!

Answer 1

Here is the code that will appear on the screen of your silverlight application. and then you can send it or something else :-)

Just create a silverlight project (with a normal main page, etc.) and replace it.

works in both 3.0 and 4.0 (havent tried 2.0 and below)

.cs

SilverlightApplication1 {     public partial class MainPage: UserControl     {         public MainPage()         {             InitializeComponent();         }

    private void UIelementShoot(object sender,

RoutedEventArgs e)         {             theImageToSend.Source = new WriteableBitmap (elementToCapture, );         }

    private void ScreenShoot(object sender,

RoutedEventArgs e)         {             theImageToSend.Source = new WriteableBitmap (LayoutRoot, null);         }

    private void Button_Click(object sender,

RoutedEventArgs e)         {

    }
} }

Answer 3

Silverlight , Silverlight - .

, -, PrintDocument ....
. , LayoutRoot .

In the links from this forum, they register the DLL in the GAC and use this method to create a screenshot. Not very nice ;-)

private void ButtonPrint_Click(object sender, System.Windows.RoutedEventArgs e)
{
    PrintDocument pd = new PrintDocument();
    pd.PrintPage += OnPrintPage;
    pd.Print("from Silverlight");
}

private void OnPrintPage(object s, PrintPageEventArgs args)
{
    args.PageVisual = LayoutRoot;
}

For someone else who stumbles upon this in the future, there is also a great option for using phantoms ( http://phantomjs.org/ )!
