I am new to programming and I have this project due on coming Tuesday. What I am trying to do is if a user enters a wrong password on the logon screen the cam takes the picture. I tried to implement my code in services but it gives me error 1053. I was wondering if somebody could fix this code for me or if file watcher is of use in my code. Please help!

Despite my comment, this is easy. Check what the error 1053 means:
ERROR_SERVICE_REQUEST_TIMEOUT
1053 (0x41D)
The service did not respond to the start or control request in a timely fashion.
Your overrides of ServiceBase methods like OnStart need to return as soon as possible. If you want to perform any ongoing work either subscribe to events or spin up a worker thread.
The .NET documentation on MSDN doesn't really cover much about the execution model of services, for this you need to look at the Win32 documentation: About Services.

I have followed instructions found on this site, which was found when I researched Stack Overflow and found this question. However, I can't seem to figure out why my code is hitting the catch block. I have a break at the IInstallationResult line, which the code hits but then goes to the catch, stating 0x80240024 (There are no updates), even though there are certainly updates available and I list them in the text box.
What am I missing here?

Turns out it was an issue with privileges. I ran as administrator and it functioned appropriately.
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 !

This one is driving me nuts... I want to write a simple C# application (with GUI) that logs into our Cisco Wireless Lan Controller (short WLC) via SSH and creates guest users. This would be quite easy with SSH.NET if not Cisco for whatever reason decided to not allow non-interactive logon - meaning you can't pass on username and password but have to type it in at the console. Even worse: they put an additional (non-functional) user prompt in front of the actual user prompt. God...
Anyway I figured it out using plink.exe and it is working quite ok, however I want to inspect the terminal output so I can decide if some commands were executed correctly. I want to use the output for the login too as the prompt appears somewhat slow and I can't rely on constant timing.
I have found some articles about redirection of the output (eg Process.start: how to get the output?), but it's just not working. I was only able to collect the output when plink.exe has been closed, but I need to read the output live with plink still running.
Here's my code so far:

I'd really appreciate your help!
For whom it may be of any help: I solved it using SSH.NET again, but this time not using the built in functions to login in but by using in combination with ShellStream to manually process in- and output. Working great so far.

Thank you.
The problem is that JabberClient's event is handled in j_OnAuthenticate and the timer's event is handled with it:
Schedular = new Timer(new TimerCallback(j_OnAuthenticate));
...
JabberClient j = new JabberClient();
j.OnAuthenticate += new bedrock.ObjectHandler(j_OnAuthenticate);
And in j_OnAuthenticate the first thing you do is cast the sender to JabberClient
private void j_OnAuthenticate(object sender)
{
try
{
JabberClient j = (JabberClient)sender;
...
}
catch (Exception ex)
{
WriteToFile("Simple Service Error on: {0} " + ex.Message + ex.StackTrace);
//Stop the Windows Service.
using (System.ServiceProcess.ServiceController serviceController = new System.ServiceProcess.ServiceController("SparkBirthDayGreeting"))
{
serviceController.Stop();
}
}
The catch block handles and logs the exception.
You would have to change the code to do different things depending on the sender e.g.
if(sender is JabberClient)
{
//do something
}
else if(sender is Timer)
{
//do something else
}
Or give the timer a different callback function

On scheduleTimer = new Timer(); got error
(This member is defined more than one)
Error:
Ambiguity between 'BirthdayEmailService.BirthdayEmailService.scheduleTimer' and 'BirthdayEmailService.BirthdayEmailService.scheduleTimer'
Also got error on BirthdayEmailService.Designer.cs this is file of design tool of service
error is :
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
this.eventLogEmail = new System.Diagnostics.EventLog();
**this.scheduleTimer = new System.Windows.Forms.Timer(this.components);**
((System.ComponentModel.ISupportInitialize)(this.eventLogEmail)).BeginInit();
//
// BirthdayEmailService
//
this.ServiceName = "BirthdayEmailService";
((System.ComponentModel.ISupportInitialize)(this.eventLogEmail)).EndInit();
}
those part is bold there is getting error as same as.
(This member is defined more than one)
Error:
Ambiguity between 'BirthdayEmailService.BirthdayEmailService.scheduleTimer' and 'BirthdayEmailService.BirthdayEmailService.scheduleTimer'
It could be because the name of the class and the namespace are the same one. See this post.
