VB.NET窗口画面撷取（ALT + PRINTSCREEN） [英] VB.NET Window Screen Capture (ALT+PRINTSCREEN)

问题描述

我发现，code的地方，我发现它非常有用，但我想找到一种方法，使其工作，因此只捕获指定的窗口的目标。也许有一个进程ID或窗口名称。即使该窗口是不活动。

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 Window Name. Even if that window is not active.

我不想使该窗口有效，但希望得到一个屏幕捕捉一样，如果我在做ALT + PRINTSCREEN就可以了。

I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it.

下面是code，它适用于全屏幕捕获

Here is the code that works for full Screen Capture

    Private bmpScreenShot As Bitmap
    Private gfxScreenshot As Graphics

    bmpScreenShot = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb)

    gfxScreenshot = Graphics.FromImage(bmpScreenShot)
    gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy)

    bmpScreenShot.Save(fileName, ImageFormat.Png)

我使用Visual Basic 2008例preSS

I use the Visual Basic 2008 Express

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

    Dim SC As New ScreenShot.ScreenCapture

    SC.CaptureScreenToFile("c:\accops\test\desktop2.jpg", Imaging.ImageFormat.Jpeg)
