Determine the pressed letter key depending on the language layout

Is it possible to determine the pressed letter key depending on the layout?
Here is code (class):
class GlobalKeyboardHookEventArgs : HandledEventArgs
{
public GlobalKeyboardHook.KeyboardState KeyboardState { get; private set; }
public GlobalKeyboardHook.LowLevelKeyboardInputEvent KeyboardData { get; private set; }
public GlobalKeyboardHookEventArgs(
GlobalKeyboardHook.LowLevelKeyboardInputEvent keyboardData,
GlobalKeyboardHook.KeyboardState keyboardState)
{
KeyboardData = keyboardData;
KeyboardState = keyboardState;
}
}
//Based on https://gist.github.com/Stasonix
class GlobalKeyboardHook : IDisposable
{
public event EventHandler<GlobalKeyboardHookEventArgs> KeyboardPressed;
public GlobalKeyboardHook()
{
_windowsHookHandle = IntPtr.Zero;
_user32LibraryHandle = IntPtr.Zero;
_hookProc = LowLevelKeyboardProc; // we must keep alive _hookProc, because GC is not aware about SetWindowsHookEx behaviour.
_user32LibraryHandle = LoadLibrary("User32");
if (_user32LibraryHandle == IntPtr.Zero)
{
int errorCode = Marshal.GetLastWin32Error();
throw new Win32Exception(errorCode, $"Failed to load library 'User32.dll'. Error {errorCode}: {new Win32Exception(Marshal.GetLastWin32Error()).Message}.");
}
.............
and call:
private void OnKeyPressed(object sender, GlobalKeyboardHookEventArgs e)
{
KeysConverter kc = new KeysConverter();
if (e.KeyboardState == GlobalKeyboardHook.KeyboardState.KeyDown)
{
GrabbedKeys += kc.ConvertToString(e.KeyboardData.VirtualCode);
return;
}
if (e.KeyboardData.VirtualCode != GlobalKeyboardHook.VkSnapshot)
return;
}
Its work fine, if I press on keyboard 's' my programm stored 's', but how I can make same for russian keyboard layout? If keyboard layout is ru-RU, I press 's' and my app stored 'ы'?

MouseKeyHook application lags on boot and can't be closed

I've written a simple auto clicker using MouseKeyHook.
The reason I use MouseKeyHook is to detect global left clicks throughout Windows OS.
Although, when I run the .exe, the software lags on the click and after a while I can't seem to hit the 'X' button anymore and the application crashed my windows or slows down everything.
I am making this software to test our game, but this is not really helping :P
The code for the software can be found below:

How to write NFC tags while preventing WP from launching the action which is currently stored on NFC tag

I trying to allow people to write to NFC tags using my app, so that my app gets launched with a custom parameter. I want to be able to reprogram NFC tags which already have data on them.
I am using the following code but the problem is, that WP always recognizes the action which is already on the NFC tag and interrupts because it wants to launch the NFC tag action which was written anytime before.
How can I tell the OS to stop triggering the action of the tag so that I can immediately rewrite it?
public enum NfcHelperState
{
Initializing,
Waiting,
Ready,
Writing,
Finished,
Error,
NoDeviceFound
}
public class NfcHelper
{
private NfcHelperState _state = NfcHelperState.Initializing;
public NfcHelperState State
{
get { return _state; }
}
private ProximityDevice _nfcDevice;
private long _subscriptionId;
public NfcHelper()
{
Init();
}
public void Init()
{
UpdateState();
_nfcDevice = ProximityDevice.GetDefault();
if (_nfcDevice == null)
{
UpdateState(NfcHelperState.NoDeviceFound);
return;
}
UpdateState(NfcHelperState.Waiting);
}
private void UpdateState(NfcHelperState? state = null)
{
if (state.HasValue)
{
_state = state.Value;
}
if (OnStatusMessageChanged != null)
{
OnStatusMessageChanged(this, _state);
}
}
public void WriteToTag()
{
UpdateState(NfcHelperState.Ready);
_subscriptionId = _nfcDevice.SubscribeForMessage("WriteableTag", WriteableTagDetected);
}
private void WriteableTagDetected(ProximityDevice sender, ProximityMessage message)
{
UpdateState(NfcHelperState.Writing);
try
{
var str = "action=my_custom_action";
str += "\tWindowsPhone\t";
str += CurrentApp.AppId;
_nfcDevice.PublishBinaryMessage("LaunchApp:WriteTag", GetBufferFromString(str),
WriteToTagComplete);
}
catch (Exception e)
{
UpdateState(NfcHelperState.Error);
StopWaitingForTag();
}
}
private void WriteToTagComplete(ProximityDevice sender, long messageId)
{
sender.StopPublishingMessage(messageId);
UpdateState(NfcHelperState.Finished);
StopWaitingForTag();
}
private void StopWaitingForTag()
{
_nfcDevice.StopSubscribingForMessage(_subscriptionId);
}
private static IBuffer GetBufferFromString(string str)
{
using (var dw = new DataWriter())
{
dw.UnicodeEncoding = Windows.Storage.Streams.UnicodeEncoding.Utf16LE;
dw.WriteString(str);
return dw.DetachBuffer();
}
}
public delegate void NfcStatusMessageChangedHandler(object myObject, NfcHelperState newState);
public event NfcStatusMessageChangedHandler OnStatusMessageChanged;
}
WriteToTag is called when a button in my app is tapped and the app waits for a writable tag. If a writable tag is recognized, WriteableTagDetected gets called and immediately starts the writing process. However, this is interrupted by the WP dialog which asks whether to perform the NFC action or not. After writing, WriteToTagComplete should be called, where StopWaitingForTag gets called and ends the write process.
I hope you guys can help me :)

Turns out I thought the wrong way. I didn't need to wait for a tag to arrive in order to rewrite it. In fact, there's no need to do _nfcDevice.SubscribeForMessage("WriteableTag", WriteableTagDetected); before writing. Just start using PublishBinaryMessage and it will write to the tag once it arrives at the device.
My final code looks like the following:
public enum NfcHelperState
{
Initializing,
Ready,
WaitingForWriting,
FinishedWriting,
ErrorWriting,
NoDeviceFound
}
public class NfcHelper
{
private NfcHelperState _state = NfcHelperState.Initializing;
public NfcHelperState State
{
get { return _state; }
}
private ProximityDevice _nfcDevice;
private long? _writingMessageId;
public NfcHelper()
{
Init();
}

{
UpdateState();
_nfcDevice = ProximityDevice.GetDefault();

{
UpdateState(NfcHelperState.NoDeviceFound);
return;
}
UpdateState(NfcHelperState.Ready);
}
private void UpdateState(NfcHelperState? state = null)
{
if (state.HasValue)
{
_state = state.Value;
}
if (OnStatusMessageChanged != null)
{
OnStatusMessageChanged(this, _state);
}
}
public void WriteToTag()
{
StopWritingMessage();
UpdateState(NfcHelperState.WaitingForWriting);
try
{
var str = new StringBuilder();
str.Append("action=my_custom_action");
str.Append("\tWindowsPhone\t{");
str.Append(CurrentApp.AppId);
str.Append("}");
_writingMessageId = _nfcDevice.PublishBinaryMessage("LaunchApp:WriteTag", GetBufferFromString(str.ToString()),
WriteToTagComplete);
}
catch
{
UpdateState(NfcHelperState.ErrorWriting);
StopWritingMessage();
}
}
private void WriteToTagComplete(ProximityDevice sender, long messageId)
{
UpdateState(NfcHelperState.FinishedWriting);
StopWritingMessage();
}

Visual studio 2010- Application as a service in release mode

I have an desktop console application created in visual studio 2010.How do i convert it to windows service?. basically in debug mode i want it as normal app , but in release mode i want a service build output

You can do it this way:
namespace Program
{
static class Program
{
public static bool Stopped = false;
[STAThread]
static void Main(string[] args)
{
Interactive.Initialize();
Interactive.OnStopped += new Interactive.StopedDelegate(OnStopped);
Interactive.Title = Path.GetFileNameWithoutExtension(
Assembly.GetExecutingAssembly().Location);
if (args.Length == 0) Interactive.Run(RunProc);
else if (args[0] == "-svc") ServiceBase.Run(new Service());
}
public static void RunProc() { yourConsoleMain(); }
public static void OnStopped() { Stopped = true; exitFromMain(); }
}
public class Service : ServiceBase
{
public static string Name = Path.GetFileNameWithoutExtension(
Assembly.GetExecutingAssembly().Location);
public static string CmdLineSwitch = "-svc";
public static ServiceStartMode StartMode = ServiceStartMode.Automatic;
public static bool DesktopInteract = true;
public bool Stopped = false;
public Service() { ServiceName = Name; }
public void Start() { OnStart(null); }
protected override void OnStart(string[] args)
{
System.Diagnostics.EventLog.WriteEntry(
ServiceName, ServiceName + " service started.");
Thread thread = new Thread(MainThread);
thread.Start();
}
protected override void OnStop()
{
System.Diagnostics.EventLog.WriteEntry(
ServiceName, ServiceName + " service stopped.");
Stopped = true;
Application.Exit();
}
private void MainThread()
{
Interactive.Run(Program.RunProc);
if (!Stopped) Stop();
}
}
}
Let me explain this... Basically, in Main you define that your program starts as a service if it is started with argument '-svc'.
Put in RunProc() what you normally do in main(), and in OnStopped() event handler some code that will cause main() to exit.
Then, override ServiceBase and perform some basic start/stop service.
In Windows 7 and later you must explicitly define that your service can interact with desktop if you want to see some output. But there is another problem, console window cannot be shown. So I created this console simulator which can write and also read input.

This last class, Interactive, actually serve as invoker for asynchronous methods, and it is used in Main() at the beginning.
You can skip this whole second section of code if you don't want to see console window when program is run as a windows service.
I have also created an Installer class for this, but it would be just to much code on this page.
EDIT: This InteractiveForm is actually a form with designer class, but very simple, consisting only of Form and EditBox inside filling its area.

Basicallly you need 3 projects in your solution:
Application itself
WinService for production
Console Application for test purposes
So your application must have some kind of Start() method with e.g. infinite loop that does all work and maybe Stop() method to stop processing.
Winservice project must contain class derived from ServiceBase, it'l have OnStartmethod that calls your application's Start and OnStop that calls application's Stop method.
Next, in console application you do pretty much same - calling Start method in console's entry point.
So far for debug you run your console app, and for release you publish your winservice project
Winservice class might look like:
upd
Winservice codez:
public class MyWinService : ServiceBase
{
IMyApplicationService _myApplicationService;
//constructor - resolve dependencies here
public MyWinService()
{
_myApplicationService = new MyApplicationService();
}
protected override void OnStart(string[] args)
{
base.OnStart(args);
try
{
_myApplicationService.Start();
}
catch (Exception exception)
{
//log exception
}
}
protected override void OnStop()
{
base.OnStop();

Why is this simple Mobile Form not closed when using the player

I created this simple sample Form with the close button.
Everything is working as expected when NOT using the Interop.WMPLib.dll
I've seen other applications using this without problems but why isn't the Form process closed when I just add the line:
SoundPlayer myPlayer = new SoundPlayer();
and of course dispose it:
if (myPlayer != null)
{
myPlayer.Dispose();
myPlayer = null;
}
The Form closes but the debugger VS2008 is still active. The Form project and the dll are still active.
If you send me an email to xdasleepsense#gmail.com, I can send you the zipped project.
Below is the class for the dll:
using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;
using System.Runtime.InteropServices;
using WMPLib;
namespace WindowsMobile.Utilities
{
public delegate void SoundPlayerStateChanged(SoundPlayer sender, SoundPlayerState newState);
public enum SoundPlayerState
{
Stopped,
Playing,
Paused,
}
public class SoundPlayer : IDisposable
{
[DllImport("coredll")]
public extern static int waveOutSetVolume(int hwo, uint dwVolume);
[DllImport("coredll")]
public extern static int waveOutGetVolume(int hwo, out uint dwVolume);
WindowsMediaPlayer myPlayer = new WindowsMediaPlayer();
public SoundPlayer()
{
myPlayer.uiMode = "invisible";
myPlayer.settings.volume = 100;
}
string mySoundLocation = string.Empty;
public string SoundLocation
{
get { return mySoundLocation; }
set { mySoundLocation = value; }
}
public void Pause()
{
myPlayer.controls.pause();
}
public void PlayLooping()
{
Stop();
myPlayer.URL = mySoundLocation;
myPlayer.settings.setMode("loop", true);
}
public int Volume
{
get { return myPlayer.settings.volume; }
set { myPlayer.settings.volume = value; }
}
public void Play()
{
Stop();
myPlayer.URL = mySoundLocation;
myPlayer.controls.play();
}
public void Stop()
{
myPlayer.controls.stop();
myPlayer.close();
}
#region IDisposable Members
public void Dispose()
{
try
{
Stop();
}
catch (Exception)
{
}
// need this otherwise the process won't exit?!
try
{
int ret = Marshal.FinalReleaseComObject(myPlayer);
}
catch (Exception)
{
}
myPlayer = null;
GC.Collect();
}
#endregion
}
}

A MessageBox or Below solved it. Thx.
public void Dispose()
{
try
{
Stop();
}
catch (Exception)
{
}
// need this otherwise the process won't exit?!
try
{
int ret = Marshal.FinalReleaseComObject(myPlayer);
}
catch (Exception)
{
}
myPlayer = null;
GC.Collect();
//If you don't do this, it will not quit
//http://www.eggheadcafe.com/software/aspnet/31363254/media-player-freezing-app.aspx
for (int s = 0; s < 100; s++)
{
Application.DoEvents();
Thread.Sleep(1);
}
GC.WaitForPendingFinalizers();
//MessageBox.Show("Application Exiting");
}

I just found from this link: http://software.itags.org/pocketpc-developer/163455/
a hint...
So I added a messagebox:
public void Dispose()
{
try
{
Stop();
}
catch (Exception)
{
}
// need this otherwise the process won't exit?!
try
{
int ret = Marshal.FinalReleaseComObject(myPlayer);
}
catch (Exception)
{
}
myPlayer = null;
GC.Collect();
**MessageBox.Show("Application Exiting");**
}
once I click OK, the debugger also thinks it's finished. Of course I can't have the user click OK.
So what's happening here?
