WPF virtual keyboard and wpf virtual keyboard

Previously, a WPF virtual keyboard called Win32 API to simulate Keyboard Events.

The Code is as follows:

The key layout is as follows:

   <Button Name="CmdTlide" Focusable="False" Click="Button_Click"  Style="{StaticResource InformButton}"  VerticalContentAlignment="Top" HorizontalContentAlignment="Left"  Width="60" Height="60">                                    <StackPanel Orientation="Vertical" HorizontalAlignment="Left" VerticalAlignment="Top" >                                        <TextBlock    HorizontalAlignment="Left" VerticalAlignment="Top"   ><Run Text="~"/></TextBlock>                                        <TextBlock HorizontalAlignment="Left" VerticalAlignment="Bottom"   ><Run Text="'"/></TextBlock>                                    </StackPanel>                                </Button>

Trigger a keyboard event:

  private static void addNumkeyINput(byte input)        {            if (CtrlFlag)            {                CtrlFlag = false;                ShiftFlag = false;                keybd_event(input, 0, 0, 0);                keybd_event(input, 0, 0x02, 0);            }            else            {                if (!ShiftFlag)                {                    keybd_event(input, 0, 0, 0);                    keybd_event(input, 0, 0x02, 0);                }                else                {                    keybd_event(0x10, 0, 0, 0);//shift                    keybd_event(input, 0, 0, 0);                    keybd_event(input, 0, 0x02, 0);                    keybd_event(0x10, 0, 0x02, 0);                    ShiftFlag = false;                }            }        }
