模拟＆QUOT; Windows和QUOT;键和＆QUOT; + QUOT;键可放大

问题描述

Windows 7中（最终）还内置了屏幕缩放功能。按住Windows键，然后你可以使用+键放大， - 键缩小。因此，我一直在试图模仿这种组合。随着AutoIt的我曾尝试：

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}")

这些4个步骤无工作...

其实我是想用C＃的这个功能。如果我管理与AutoIt的做到这一点，我可以调用该脚本使用C＃，所以我不介意langauage。我也模拟键盘按键，因为我不知道我怎么会能够使用C＃进行放大。

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

导入位于库：

然后执行：

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