autoit3实现alt+printscreen窗口截图

#include <ScreenCapture.au3>
RunWait("C:WindowsSystem32mstsc.exe")
Local $hwnd = WinWait("远程桌面连接","", 10)
$hwnd = WinGetHandle("[active]")
ConsoleWrite($hwnd)
_ScreenCapture_CaptureWnd(@MyDocumentsDir & "TestGDI_Image.jpg", $hwnd)

　　有需求要实现alt+printscreen窗口截图, 但是C#开发很麻烦, 于是想到autoit3, 很强大, 可以实现该功能, 然后用C#调用exe就可以了
