VB.NET Window Screen Capture (ALT+PRINTSCREEN)

Question

I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or W

Answer 1

Look at this Capture screenshot of active window? Instead of this.Handle (current window) you may insert a handle of any other window (using WinAPI functions like FindWindow)

Answer 2

The easiest way to do it, though it's a hack, is this:

SendKeys.Send("{PRTSC}")
Dim Screenshot As Image = Clipboard.GetImage()
Screenshot.Save("c:\ScreenShot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

Answer 3

This will give you the Alt + Printscreen, showing only front most application.

SendKeys.Send("%{PRTSC}") 

Then continue the normal way:

Dim Screenshot As Image = Clipboard.GetImage()
Screenshot.Save("c:\ScreenShot.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

Answer 4

This works in vb.net2.0. I just used it. Here is the source code.

    Dim SC As New ScreenShot.ScreenCapture

    'captures entire desktop straight to file
    SC.CaptureScreenToFile("c:\accops\test\desktop2.jpg", Imaging.ImageFormat.Jpeg)

Answer 5

Capture the active-form.

Private Sub tsbCamera_Click(sender As Object, e As EventArgs) Handles tsbCamera.Click
    Dim bm As New Bitmap(Width, Height)
    DrawToBitmap(bm, New Rectangle(0, 0, Width, Height))
    Dim name As String = InputBox("Name it:")
    bm.Save(Application.StartupPath & "\ScreenShot\" & name & ".png", System.Drawing.Imaging.ImageFormat.Png)
End Sub
