模拟“Windows"键和“+"放大键 [英] Simulate "Windows" key and "+" key to zoom in

问题描述

Windows 7(终于)具有内置的屏幕缩放功能.按住Windows"键，然后您可以使用+"键放大，使用-"键缩小.因此，我一直在尝试模拟这种组合.使用 AutoIt 我尝试过:

Windows 7 (finally) has built-in zoom feature for the screen. Hold down the "Windows" key and you can then use the "+" key to zoom in and the "-" key to zoom out. As a result I have been trying to simulate this combination. With AutoIt I have tried:

1)

Send("{LWINDOWN}" & "+" & "{LWINUP}")

2)

$x = Chr(43)
Send("{LWINDOWN}" & $x & "{LWINUP}")

3)

Send("#{+}") ;//works but it also sends "+" key

4)

Send("{LWINDOWN}")
Sleep(10)
Send("+",1)
Sleep(10)
Send("{LWINUP}")

这 4 个步骤都不起作用...

我实际上想在 c# 上使用此功能.如果我设法用 autoit 做到这一点，我可以用 c# 调用该脚本，所以我不介意语言.我也在模拟击键，因为我不知道如何使用 c# 放大.

I actually want to use this functionality on c#. If I manage to do it with autoit I could invoke that script with c# so I don't mind the langauage. I am also simulating keystrokes because I don't know how I will be able to zoom in using c#.

推荐答案

导入位于以下位置的库:

Import the library located at:

http://inputsimulator.codeplex.com/

然后做:

 WindowsInput.InputSimulator.SimulateKeyDown
                          (WindowsInput.VirtualKeyCode.LWIN);
 WindowsInput.InputSimulator.SimulateKeyPress
                          (WindowsInput.VirtualKeyCode.OEM_PLUS);
 WindowsInput.InputSimulator.SimulateKeyUp
                          (WindowsInput.VirtualKeyCode.LWIN);
