使用InputSimulator

Question

尝试使用InputSimulator模拟键盘输入。除了使用sim.Keyboard.ModifiedKeyStroke模拟ASCII字符的输入之外，一切都工作得很好。

我尝试使用以下两种不同的方式来模拟Alt down + numpad1 + numpad4 + numpad7 + Alt up：

    sim.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LMENU, new[] { VirtualKeyCode.NUMPAD1, VirtualKeyCode.NUMPAD4, VirtualKeyCode.NUMPAD7});

和

    sim.Keyboard.KeyDown(VirtualKeyCode.LMENU);
    sim.Keyboard.KeyDown(VirtualKeyCode.NUMPAD1);
    sim.Keyboard.KeyUp(VirtualKeyCode.NUMPAD1);
    sim.Keyboard.KeyDown(VirtualKeyCode.NUMPAD4);
    sim.Keyboard.KeyUp(VirtualKeyCode.NUMPAD4);
    sim.Keyboard.KeyDown(VirtualKeyCode.NUMPAD7);
    sim.Keyboard.KeyUp(VirtualKeyCode.NUMPAD7);
    sim.Keyboard.KeyUp(VirtualKeyCode.LMENU);

这两样都不管用。我试着打印出控制台中的键状态，真正的按键和模拟按键都给出了相同的结果：

   LMenu key down
   NumPad1 key down
   NumPad1 key up
   NumPad4 key down
   NumPad4 key up
   NumPad7 key down
   NumPad7 key up
   LMenu key up

我认为应该是库的一些问题：问题1。有人能帮我一下吗？还有别的办法吗？

更新1

我发现"Alt+Tab“也没有在Win8中工作。我想这可能是同样的原因，所以我试着先解决这个问题。事实证明，它们是两个不同的问题：

1. 要使"Alt+Tab“起作用，我需要在"app.manifest”中设置uiAccess=true，并使用测试数字签名对".exe“文件进行签名；
2. 模拟ASCII字符的输入仍然不能工作。

使用keybd_event与MapVirtualKey或如果使用SendInput添加到输入的扫描MapVirtualKey。

下面是两者的例子，

using System;
using System.Threading;
using System.Runtime.InteropServices;

namespace kbd_events_example
{
    static class Program
    {
        #pragma warning disable 649

            public KEYBOARDMOUSEHARDWARE Data;
        }
        [StructLayout(LayoutKind.Explicit)]
        //This is KEYBOARD-MOUSE-HARDWARE union INPUT won't work if you remove MOUSE or HARDWARE
        internal struct KEYBOARDMOUSEHARDWARE

            public KEYBDINPUT Keyboard;
            [FieldOffset(0)]
            public HARDWAREINPUT Hardware;
            [FieldOffset(0)]
            public MOUSEINPUT Mouse;
        }

        static void Main()
        {
            Thread.Sleep(5000); //wait 5 seconds, so you can focus the Notepad
            keybd_event((int)VK.MENU, (byte)MapVirtualKey((uint)VK.MENU, 0), 0, 0); //Alt Press

            Thread.Sleep(2000); //wait 2 seconds
            INPUT[] inputs = new INPUT[] {
                new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.MENU, Flags = 0, Scan = (ushort)MapVirtualKey((uint)VK.MENU, 0), ExtraInfo = IntPtr.Zero, Time = 0}}},
                new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.NUMPAD2, Flags = 0, Scan = (ushort)MapVirtualKey((uint)VK.NUMPAD2, 0), ExtraInfo = IntPtr.Zero, Time = 0}}},
                new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.NUMPAD2, Flags = 2, Scan = (ushort)MapVirtualKey((uint)VK.NUMPAD2, 0), ExtraInfo = IntPtr.Zero, Time = 0}}},
                new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.MENU, Flags = 2, Scan = (ushort)MapVirtualKey((uint)VK.MENU, 0), ExtraInfo = IntPtr.Zero, Time = 0}}}
            };
            SendInput((uint)inputs.Length, inputs, Marshal.SizeOf(typeof(INPUT)));
        }
    }
}

至于InputSimulator，您需要使用SendInput或带有MapVirtualKey的keybd_event编写自己的类来处理输入.

Answer 2

你用的是什么版本的InputSimulator。版本1.0.4有ModifiedKeyStroke(IEnumerable modifierKeyCodes，IEnumerable keyCodes)方法，它应该允许以下内容：

sim.Keyboard.ModifiedKeyStroke(new[] { VirtualKeyCode.LMENU }, new[] { VirtualKeyCode.NUMPAD1, VirtualKeyCode.NUMPAD4, VirtualKeyCode.NUMPAD7 });
