Hotkey with MouseKeyHook not catching event in C#

I'm building a word lookup application that runs in system tray and when you scan a block of a few words and then press a hotkey combination like Shift + C + V for example.
However, the problem is that when I test it on my personal machine, it works fine. But when through Tester's machine, it is not possible to catch the hotkey press event.
I'm using MouseKeyHook's library.
May everyone help you
Here is my code
enum KeyModifier
{
None = 0,
Alt = 1,
Control = 2,
Shift = 4
}
public Main()
{
System.Diagnostics.Process myProcess = System.Diagnostics.Process.GetCurrentProcess();
myProcess.PriorityClass = System.Diagnostics.ProcessPriorityClass.High;
InitializeComponent();
this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;
notify.Visible = true;
this.FormBorderStyle = FormBorderStyle.None;
this.Padding = new Padding(borderSize);
this.panel1.BackColor = borderColor;
this.BackColor = borderColor;
if (File.Exists("hotkey.txt") == false)
{
string noidung = "Shift+F";
File.WriteAllText("hotkey.txt", noidung);
}
manage = new ManageDictionary();
conn = ConnectDB.Connect();
ctrl = new ControlData(m_Events, data, txtSearch);
ctrl.SubscribeGlobal();
resetHotKey();
}
public void resetConnection()
{
conn = ConnectDB.Connect();
}
public void resetHotKey()
{
string[] hot;
string key;
this.hotkey_Events = Hook.GlobalEvents();
if (File.Exists("hotkey.txt"))
{
hot = File.ReadAllLines("hotkey.txt");
key = hot[0];
}
else
{
key = "Shift+F";
}
var subhotkey = Combination.FromString(key);
Action action = () => {
string keyword = Clipboard.GetText().Trim();
if (keyword.Equals(""))
return;
try
{
conn.Open();
ArrayList re;
re = manage.findWord(conn, keyword);
if (re.Count == 0)
{
Dictionary a = new Dictionary(0, "Không tìm thấy kết quả", "", "", "", "");
re.Add(a);
Notification noti = new Notification(re, keyword);
Thread.Sleep(1000);
noti.Show();
}
else
{
Notification noti = new Notification(re, keyword);
Thread.Sleep(1000);
noti.Show();
}
}
catch (Exception)
{
MessageBox.Show("Kết nối thất bại");
}
conn.Close();
};
var assignment = new Dictionary<Combination, Action>
{
{subhotkey, action}
};
this.hotkey_Events.OnCombination(assignment);
}

SAPI does not implement phonetic alphabet selection. Speech Command App

In my speech command app, I am loading files from an external source, processing that data and loading them into a list of possible commands for execution
When I run the app, I get the message in the console
Main.exe Information: 0: SAPI does not implement phonetic alphabet selection.
I tried solutions such as adding
gram.Culture = New System.Globalization.CultureInfo("en-GB")
I think this is either outdated or does not work on this type of WPF application
Any tips?
Code:
{
InitializeComponent();
}

private Choices cmd;
private void Button_Click_1(object sender, RoutedEventArgs e)
{
b1.IsEnabled = false;
Choices list = new Choices();
cmd = Singleton.getInstance().getChoices();
list.Add(new string[] { "hello", "test", "it works", "sup", "windows", "grenade" });
Grammar gr = new Grammar(new GrammarBuilder(cmd));
try
{
recog.RequestRecognizerUpdate();
recog.LoadGrammar(gr);
recog.SpeechRecognized += Recog_SpeechRecognized;
recog.SetInputToDefaultAudioDevice();
recog.RecognizeAsync(RecognizeMode.Multiple);

No Book Results from ISBNDB with Valid ISBN

I've got a weird issue here. I'll start by explaining my program:
I have a C# application. The main goal of the program is to get information about a book based on its ISBN. The ISBN is passed to the program via a TCP/IP scanner on an Android device. The ISBN is then put into a valid URL which is used to grab the XML data from ISBNDB.com.
The issue that I am having is this:
When I query an ISBN typed into a TextBox, the program works fine. When I query an ISBN scanned from the reader, it returns 'No Results'
I have implemented various ways to try and get to the bottom of this case. Right before the XML is read, I have a message box show me the XML that it received:
As you can see, it shows no results. However, when I visit the URL (Also gotten from within the program):
I get this in Microsoft Edge:
Which, is exactly what I would think the application would get as well.
Does anyone know what is going on? If so, what can I do to fix it and how can my code be improved to eliminate this error?
For those interested, here is my code:

Possible Hint: Could it have something to do with how I have threads working?
*Edit: * **I have updated the code to have the barcode be put in a textBox and then used to fetch the data. This does not seem to work either because it 'Cannot access the control on a thread other than on which it was created'

If manual user input succeed while automated input fail, the simplest hack is just replacing the automated input to a call to manual control BeginInvoke. For your code this would be :
textBarcode.BeginInvoke(new Action(() => {
textBarcode.Text = bCode;
GetXMLBarcodeData();
}));

I use this list box for a sort of a playlist for a radio. But i need my items to be saved even when the user clicks back button or is under lock screen. Please help me save my dear items.

There are several ways to store data between "sessions":
Using files in the IsolatedStorage to serialize to/deserialize from.
Using IsolatedStorageSettings for the same purpose, but with smaller amount of data.
Using database, either SQL CE or sqlite
I suggest that you use the first method because it is the easiest one and you will get the least errors with it. Simply serialize the data to the file whenever you need to, either on application closing or when it changes. You then load the data on startup from the file (if it exists) and fill the initial list.

Searching the web through C# Speech

Okay. I have been working on a speech recognition program. I want to make it when you say something like "search the web for images of cats" it will open the browser and search for images of cats. I made a textbox to receive the inputs of the user's speech, but I have been stumped to find out how to retrieve the text from the textbox and send it to the web.
Where textbox1.text = speech; is where the speech is converted to text.

Why do you need to retrieve the text from the textbox, when you have the text
string speech = e.Result.Text;
already? All you need to do is URLEncode the string (sample function here) and open a browser window with the URL.

Use Google image search API developer, get image url, declare xml document, make variables.
