How to fix issue of zkemkeeper.dll realtime events inside windows service?

i'm setting up windows service and want it to sync the device attendance to SQL Server database using zkemkeeper real time event. i have successfully created service as well as tested the service on my local system which run windows 10 and another one window 8 service work fine and sync the attendance record to DB server at real time. Now after successful testing on local system i deployed service over production server where service successfully established the connection with device but it didn't respond to Real time event for testing purpose i have created winform app and run it over the server and find out it is working and listening to real time event but i need service to work properly not win form application any help will be appreciated thanks below is my code !

CrossGeolocator GetPositionAsync exits loop/method

I want to keep the phone's location quite often in an App, so I'm using the GetPositionAsync method, and keep calling that. I've written some code, and when I attach that in a simple OnAppearing method everything works fine. If I write it in a method or while loop, when it gets to the GetPositionAsync or some other local database things, I think only awaitable methods, it goes right out of the loop/method. I am using async. Any ideas?
var locator = CrossGeolocator.Current;
locator.DesiredAccuracy = 20;
var position = await locator.GetPositionAsync(TimeSpan.FromSeconds(10));
location.Latitude = position.Latitude;
location.Longitude = position.Longitude;
await App.LocationDatabase.SaveLocationAsync(location);
await Task.Delay(TimeSpan.FromSeconds(10));

You're not sharing any loop code, so it's hard to reproduce your issue.
Anyway, you shouldn't call GetPositionAsync in a loop, use the StartListeningAsync method and connect to the PositionChange event instead.
async Task StartListeningAsync()
{
if(CrossGeolocator.Current.IsListening)
return;
await CrossGeolocator.Current.StartListeningAsync(TimeSpan.FromSeconds(5), 10, true);
CrossGeolocator.Current.PositionChanged += PositionChanged;
CrossGeolocator.Current.PositionError += PositionError;
}
private void PositionChanged(object sender, PositionEventArgs e)
{
//If updating the UI, ensure you invoke on main thread
var position = e.Position;
var output = "Full: Lat: " + position.Latitude + " Long: " + position.Longitude;
output += "\n" + $"Time: {position.Timestamp}";
output += "\n" + $"Heading: {position.Heading}";
output += "\n" + $"Speed: {position.Speed}";
output += "\n" + $"Accuracy: {position.Accuracy}";
output += "\n" + $"Altitude: {position.Altitude}";
output += "\n" + $"Altitude Accuracy: {position.AltitudeAccuracy}";
Debug.WriteLine(output);
}
private void PositionError(object sender, PositionErrorEventArgs e)
{
Debug.WriteLine(e.Error);
//Handle event here for errors
}
async Task StopListeningAsync()
{
if(!CrossGeolocator.Current.IsListening)
return;
await CrossGeolocator.Current.StopListeningAsync();
CrossGeolocator.Current.PositionChanged -= PositionChanged;
CrossGeolocator.Current.PositionError -= PositionError;

How to get the newly opened apps WPF

Is there any way to get the newly open apps? I have a function that gets the running apps every 10 seconds, place them on a listbox and sends them to the other window if you click the send button.
What I wanted to happen is to get the newly opened app and send it to the other window. For example:
for the first 10 secs, I have opened notepad and chrome, after clicking send, those two will be sent to the other window. For the next 10 secs, I opened another app which is firefox. So my opened apps are now notepad, chrome and firefox so when I click send, I only want firefox to be sent to the other window so it wouldn't be redundant. Is this even possible?
There's the codes, in case if it brings of any help.
private void SendData()
{
String processID = "";
String processName = "";
String processFileName = "";
String processPath = "";
string hostName = System.Net.Dns.GetHostName();
listBox1.BeginUpdate();
try
{
for (int i = 0; i < listBox1.Items.Count; i++)
{
piis = GetAllProcessInfos();
try
{
processID = piis[i].Id.ToString();
processName = piis[i].Name.ToString();
processFileName = piis[i].FileName.ToString();
processPath = piis[i].Path.ToString();
output.Text += "\n\nSENT DATA : \n\t" + processID + "\n\t" + processName + "\n\t" + processFileName + "\n\t" + processPath + "\n";
}
catch (Exception ex)
{
wait.Abort();
output.Text += "Error..... " + ex.StackTrace;
}
NetworkStream ns = tcpclnt.GetStream();
String data = "";
data = "--++" + " " + processID + " " + processPath + " " + processFileName + " " + hostName;
if (ns.CanWrite)
{
byte[] bf = new ASCIIEncoding().GetBytes(data);
ns.Write(bf, 0, bf.Length);
ns.Flush();
}
}
}
finally
{
listBox1.EndUpdate();
}
}

Store the Id of previously sent processes in a list and only send the process info of a process if it's id is not in the list.
private List<int> listedProcesses = new List<int>();
//...
try
{
if(!listedProcesses.Contains(piis[i].Id)
{
listedProcesses.Add(piis[i].Id);
processID = piis[i].Id.ToString();
processName = piis[i].Name.ToString();
processFileName = piis[i].FileName.ToString();
processPath = piis[i].Path.ToString();
output.Text += "\n\nSENT DATA : \n\t" + processID + "\n\t" + processName + "\n\t" + processFileName + "\n\t" + processPath + "\n";
}
}
//...
Also: when you close processes these two lines will no longer be valid:
for (int i = 0; i < listBox1.Items.Count; i++)
{
piis = GetAllProcessInfos();
Because the number of processes can now be lower than the number of items in the listbox.
To keep them in sync you will also have to remove items from the listbox when processes are closed.
To fix it even more efficient (and easier) you could simply clear the listbox and add a new item for each process returned by GetAllProcessInfos();

Have a hook as described here: How to hook into application and process startup in windows?
using System.Management;
// Run this in another thread and make sure you dispose the event watcher before exit
var start = new ManagementEventWatcher(new WqlEventQuery("SELECT * FROM Win32_ProcessStartTrace"));
start.EventArrived += new EventArrivedEventHandler(delegate (object sender, EventArrivedEventArgs e) {
console.WriteLine("Name: {0}, Command Line: {1}", e.NewEvent.Properties["ProcessName"].Value, e.NewEvent.Properties["Commandline"].Value);
});
start.Start()

Entering information into database with visual studio form

I am encountering a problem when I attempt to enter information into a database that is connected to my visual studio 2012 form. When I start debugging if I enter information into the fields and hit submit, nothing gets entered into my database. If I enter the information again and hit submit, the information then will write to my database. I am not really great at programming, so I used the data sources to link my visual studio form and my database.
This is what my form looks like;
data form before entry
This is what my form looks like with data I enter;
data form with information
This is what happens when you hit submit;
confirmation message
This is the database after hitting submit the first time; db entries after first submission
This is what happens when I enter the information again; db entries after second submission
Any entries after this will enter correctly, and things are great. I am confused as to why information (besides the null entry) wont enter until the second time I click submit. While it "technically works" it's not quite right. Any help on the issue would be much appreciated.
Here is my code for my submit button in my New Customer Form;
namespace WindowsFormsApplication2
{
public partial class frmNewCustomer : Form
{
public frmNewCustomer()
{
InitializeComponent();
}
private void btnAddCustomer_Click(object sender, EventArgs e)
{
string cstFName;
string cstLName;
string cstAddress;
string cstCity;
string cstState;
string cstZip;
string cstPhone;
string cstEmail;
cstFName = cstFNameTxtBox.Text;
cstLName = cstLNameTxtBox.Text;
cstAddress = cstAddressTxtBox.Text;
cstCity = cstCityTxtBox.Text;
cstState = cstStateTxtBox.Text;
cstZip = cstZipTxtBox.Text;
cstPhone = cstPhoneTxtBox.Text;
cstEmail = cstEmailTxtBox.Text;
// exception handler for empty fields
if (cstFName == "")
{
MessageBox.Show("Please enter your first name!");
}
else if (cstLName == "")
{
MessageBox.Show("Please enter your last name!");
}

"Has been added to the database.");
}
this.tblCustomersBindingSource.AddNew();
this.tblCustomersBindingSource.EndEdit();
this.tblCustomersTableAdapter.Update(this.dataSet1.tblCustomers); // Updating the DB Table
}
private void frmNewCustomer_Load(object sender, EventArgs e)
{
// TODO: This line of code loads data into the 'dataSet1.tblCustomers' table. You can move, or remove it, as needed. Loads it into start of form!
// this.tblCustomersTableAdapter.Fill(this.dataSet1.tblCustomers);
}
}
}
I realize my exception handling is janky at best, but this is more about creating a few forms that read and write data to a db. I appreciate any help anyone is able to offer,

If this weren't winforms (not sure that it matters), the typical flow is this:
Create a connection.
Write your insert statement.
Do data validation.
Submit to database.
Commit transaction.
try this:
bool shouldSubmit = false;
// exception handler for empty fields
if (cstFName == "")
{
MessageBox.Show("Please enter your first name!");
}
else if (cstLName == "")
{
MessageBox.Show("Please enter your last name!");
}
else if (cstAddress == "")
{
MessageBox.Show("Please enter your address!");
}
else if (cstCity == "")
{
MessageBox.Show("Please enter your city!");
}
else if (cstState == "")
{
MessageBox.Show("Please enter your state!");
}
else if (cstZip == "")
{
MessageBox.Show("Please enter your zip!");
}
else if (cstPhone == "")
{
MessageBox.Show("Please enter your Phone!");
}
else if (cstEmail == "")
{
MessageBox.Show("Please enter your email!");
}
else
{
shouldSubmit = true;
MessageBox.Show("First Name: " + cstFName + " Last Name: " + cstLName + "\r\n" +
"Address: " + cstAddress + "\r\n" +
"City: " + cstCity + " State: " + cstState + " Zip: " + cstZip + "\r\n" +
"Phone: " + cstPhone + " Email: " + cstEmail + "\r\n" + "\r\n" +
"Has been added to the database.");
}
if(shouldSubmit)
{
this.tblCustomersBindingSource.AddNew();
this.tblCustomersBindingSource.EndEdit();
this.tblCustomersTableAdapter.Update(this.dataSet1.tblCustomers); // Updating the DB Table
}

Why does program lag and freeze while starting process?

I have a code that is supposed to start a process in order to render animation. It works great and starts the process and all, but while the process is running, my program says not responding, and freezes refusing to update progress at all.
Here is the code that should be causing the issue:

{
while (currentFrame <= lastFrame)
{
bool rendering = IsRendering("cmd");
if (rendering == false)

renderBatch.Write('"' + renderPathField.Text + '"' + " -rd " + '"' + imagePath.Text + '"' + " -s " + currentFrame + " -e " + currentFrame + " " + '"' + sceneFile.Text + '"');
renderBatch.Close();
var renderProcess = new Process();
renderProcess.StartInfo = new ProcessStartInfo(batchFile);
//renderProcess.StartInfo.Arguments = '"' + renderPathField.Text + '"' + " -rd " + '"' + imagePath.Text + '"' + " -s " + currentFrame + " -e " + currentFrame + " " + '"' + sceneFile.Text + '"';
renderProcess.StartInfo.UseShellExecute = false;
//renderProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
renderProcess.Start();

UI updates need to happen on a different thread than the main process, otherwise it will wait until the entire process is complete before showing you the updated UI.
Since you have a lot of "process" code inside your form there's not a simple fix - you will need to start the processing in another thread and set up events to pass updates back to the UI.
