我很难找到一种方法来以编程方式按下右移键。我需要一把上下键(按下/松开(。
我拥有的是:
SendKeys.Send("{RSHIFT}")
我知道这种转变就像:
SendKeys.Send("+")
我想这只是一个移位键,但我需要一个右移位键。
有人能帮我查一下这个密码吗?
使用键bd_event,您不需要窗口句柄
VB:
Public Class MyKeyPress
<DllImport("user32.dll", CharSet:=CharSet.Auto, CallingConvention:=CallingConvention.StdCall)>
Public Shared Sub keybd_event(ByVal bVk As UInteger, ByVal bScan As UInteger, ByVal dwFlags As UInteger, ByVal dwExtraInfo As UInteger)
End Sub

Public Shared Sub Send(key As Keys)
Select Case key
Case Keys.A
keybd_event(&H41, 0, 0, 0)
Case Keys.Left
keybd_event(&H25, 0, 0, 0)
Case Keys.LShiftKey
keybd_event(&HA0, 0, 0, 0)
Case Keys.RShiftKey
keybd_event(&HA1, 0, 0, 0)
Case Else
Throw New NotImplementedException()
End Select
End Sub
End Class
C#:
public static class MyKeyPress
{
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern void keybd_event(uint bVk, uint bScan, uint dwFlags, uint dwExtraInfo);
// To get other key codes check bellow link
// http://www.kbdedit.com/manual/low_level_vk_list.html
public static void Send(Keys key)
{
switch (key)
{
case Keys.A:
keybd_event(0x41, 0, 0, 0);
break;
case Keys.Left:
keybd_event(0x25, 0, 0, 0);
break;
case Keys.LShiftKey:
keybd_event(0xA0, 0, 0, 0);
break;
case Keys.RShiftKey:
keybd_event(0xA1, 0, 0, 0);
break;
default: throw new NotImplementedException();
}
}
}
用法:
MyKeyPress.Send(Keys.LShiftKey)
在一些创造性的关键词组合后发现了这一点
它建立在发送密钥码的基础上:
Keys key = Keys.RShiftKey;//Right shift key
SendMessage(Process.GetCurrentProcess().MainWindowHandle, WM_KEYDOWN, (int)key, 1);
我不知道这里的用例是什么,但要注意传递的窗口句柄参数:Process.GetCurrentProcess().MainWindowHandle
。
这会将击键发送给自己。如果您试图将其发送到另一个进程/程序,则需要传递该程序的窗口句柄。
