WPF 虚拟键盘
之前做了一款WPF虚拟键盘，调用Win32的API，可以模拟键盘事件。
现将代码分享如下：
按键布局如下：
<Button Name="CmdTlide" Focusable="False" Click="Button_Click" Style="{StaticResource InformButton}" VerticalContentAlignment="Top" HorizontalContentAlignment="Left" Width="" Height="">
<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>
点击事件：
private void Button_Click(object sender, RoutedEventArgs e)
{
System.Windows.Controls.Button keybtn = sender as System.Windows.Controls.Button;
#region//First Row
if (keybtn.Name == "CmdTlide")
{
addNumkeyINput(0xc0);
}
else if (keybtn.Name == "cmd1")

触发键盘事件：
private static void addNumkeyINput(byte input)

keybd_event(input, , , );
keybd_event(input, , 0x02, );
}
else
{
if (!ShiftFlag)
{
keybd_event(input, , , );
keybd_event(input, , 0x02, );
}
else
{
keybd_event(0x10, , , );//shift
keybd_event(input, , , );
keybd_event(input, , 0x02, );
keybd_event(0x10, , 0x02, ); ShiftFlag = false;
}
}
}
