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="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>
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") { addNumkeyINput(0x31); } else if (keybtn.Name == "cmd2") { addNumkeyINput(0x32); } else if (keybtn.Name == "cmd3") { addNumkeyINput(0x33); } else if (keybtn.Name == "cmd4") { addNumkeyINput(0x34); } else if (keybtn.Name == "cmd5") { addNumkeyINput(0x35); } else if (keybtn.Name == "cmd6") { addNumkeyINput(0x36); } else if (keybtn.Name == "cmd7") { addNumkeyINput(0x37); } else if (keybtn.Name == "cmd8") { addNumkeyINput(0x38); } else if (keybtn.Name == "cmd9") { addNumkeyINput(0x39); } else if (keybtn.Name == "cmd0") { addNumkeyINput(0x30); } else if (keybtn.Name == "cmdminus")//-_ { addNumkeyINput(0xbd); } else if (keybtn.Name == "cmd1")//+= { addNumkeyINput(0xbb); } else if (keybtn.Name == "cmdBackspace")//backspace { AddKeyBoardINput(0x08); } #endregion #region//Second Row else if (keybtn.Name == "CmdTab") { AddKeyBoardINput(0x09); } else if (keybtn.Name == "CmdQ") { AddKeyBoardINput(0x51); } else if (keybtn.Name == "Cmdw") { AddKeyBoardINput(0x57); } else if (keybtn.Name == "CmdE") { AddKeyBoardINput(0X45); } else if (keybtn.Name == "CmdR") { AddKeyBoardINput(0X52); } else if (keybtn.Name == "CmdT") { AddKeyBoardINput(0X54); } else if (keybtn.Name == "CmdY") { AddKeyBoardINput(0X59); } else if (keybtn.Name == "CmdU") { AddKeyBoardINput(0X55); } else if (keybtn.Name == "CmdI") { AddKeyBoardINput(0X49); } else if (keybtn.Name == "CmdO") { AddKeyBoardINput(0X4F); } else if (keybtn.Name == "CmdP") { AddKeyBoardINput(0X50); } else if (keybtn.Name == "CmdOpenCrulyBrace") { addNumkeyINput(0xdb); } else if (keybtn.Name == "CmdEndCrultBrace") { addNumkeyINput(0xdd); } else if (keybtn.Name == "CmdOR") { addNumkeyINput(0xdc); } #endregion #region///Third ROw else if (keybtn.Name == "CmdCapsLock")//caps lock { AddKeyBoardINput(0x14); if (checkImage.Visibility != Visibility.Visible) { checkImage.Visibility = Visibility.Visible; } else { checkImage.Visibility = Visibility.Hidden; } } else if (keybtn.Name == "CmdA") { AddKeyBoardINput(0x41); } else if (keybtn.Name == "CmdS") { AddKeyBoardINput(0x53); } else if (keybtn.Name == "CmdD") { AddKeyBoardINput(0x44); } else if (keybtn.Name == "CmdF") { AddKeyBoardINput(0x46); } else if (keybtn.Name == "CmdG") { AddKeyBoardINput(0x47); } else if (keybtn.Name == "CmdH") { AddKeyBoardINput(0x48); } else if (keybtn.Name == "CmdJ") { AddKeyBoardINput(0x4A); } else if (keybtn.Name == "CmdK") { AddKeyBoardINput(0X4B); } else if (keybtn.Name == "CmdL") { AddKeyBoardINput(0X4C); } else if (keybtn.Name == "CmdColon")//;: { addNumkeyINput(0xba); } else if (keybtn.Name == "CmdDoubleInvertedComma")//'" { addNumkeyINput(0xde); } else if (keybtn.Name == "CmdEnter") { AddKeyBoardINput(0x0d); } #endregion #region//Fourth Row else if (keybtn.Name == "CmdShift" || keybtn.Name == "CmdlShift") { if (CtrlFlag) { CtrlFlag = false; ShiftFlag = false; changeInput(); } else { ShiftFlag = true; } } else if (keybtn.Name == "CmdZ") { AddKeyBoardINput(0X5A); } else if (keybtn.Name == "CmdX") { AddKeyBoardINput(0X58); } else if (keybtn.Name == "CmdC") { AddKeyBoardINput(0X43); } else if (keybtn.Name == "CmdV") { AddKeyBoardINput(0X56); } else if (keybtn.Name == "CmdB") { AddKeyBoardINput(0X42); } else if (keybtn.Name == "CmdN") { AddKeyBoardINput(0x4E); } else if (keybtn.Name == "CmdM") { AddKeyBoardINput(0x4D); } else if (keybtn.Name == "CmdLessThan")//<, { addNumkeyINput(0xbc); } else if (keybtn.Name == "CmdGreaterThan")//>. { addNumkeyINput(0xbe); } else if (keybtn.Name == "CmdQuestion")//?/ { addNumkeyINput(0xbf); } else if (keybtn.Name == "CmdSpaceBar") { AddKeyBoardINput(0x20); } #endregion #region//Last row else if (keybtn.Name == "CmdCtrl" || keybtn.Name == "CmdlCtrl")//ctrl { if (ShiftFlag) { ShiftFlag = false; CtrlFlag = false; } else { CtrlFlag = true; } //AddKeyBoardINput(0x11); } else if (keybtn.Name == "CmdpageUp") { AddKeyBoardINput(0x21); } else if (keybtn.Name == "CmdpageDown") { AddKeyBoardINput(0x22); } else if (keybtn.Name == "CmdClose")//关闭键盘 { //this.Opacity = 0; // this.Close(); // this.keyboard.Visibility = Visibility.Hidden; //this.keyboard.Focusable = false; System.Windows.Application.Current.Shutdown(); } #endregion }
触发键盘事件:
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; } } }
