oh OK
Those are good ideas.
Guess I'll write the helper programs first, and a skeleton service for testing. And the tray, not sure how to write one but I'll figure it out.
Thanks!

if you wanted to cut out writing the 'boilerplate' yourself, look at something like cinchoo http://cinchoo.com/category/application-host/?orderby=ID&order=ASC[^] - my only bugbear with it is its not open source - there are other 'service frameworks' out there iirc - while writing a service from scratch once is 'useful', the real work is the service 'tasks', so using a pre-built framework allows you to focus on that

Avoid the registry; use a config file (of your own design if you like).
If the Service(s) store status in the database, then any number of clients (Console, WinForms, Tray) can report status and allow control.
A while back I wrote a system of Windows Services that involved a main process that read its instructions from the database and ran each individual Service as instructed.
I suspect that few newbies are aware that a "service process" can run multiple "service threads" at once -- it's not a 1:1 relationship.
public static void Run(
ServiceBase[] services
)
http://msdn.microsoft.com/en-us/library/6esb073b(v=vs.110).aspx[^]
In this way, I could have the process on server "CAT" run Services "Scratch" and "Purr", while the process on server "DOG" could run Services "Wag" and "Bark" and moving Services from one server to another was simple. All servers had exactly the same code deployed.

Could you expand the thought on the config file.
Like an ini file stored in App Data of windows?
Best location for a config,
I understand being able to just copy the files over to another server in which I approve of, and quickly install the service and be up and running.

That's user-specific. I have used the directory where the application is deployed. And more recently I've been using the C:\ProgramData directory.

.Net applications have a "app.config" file which can be added to the application and where one can retrieve and store information.
http://msdn.microsoft.com/en-us/library/ms184658.aspx[^]
Be careful with that file because if you make it ill formed the application will not load and figuring out that problem is difficult.
jkirkerx wrote: I guess the windows app could also start and stop the service as well
A windows service is a windows service, so I am not exactly sure what you mean.
It is possible to structure the build such that one can have a command line executable and a windows service but you probably don't want to try that for your first service.
You might want to also looking into a logging API. Helps in figuring out window service errors.

Well it dawned on me that I already have a configuration file in the web application that I can adsorb for the database connector string and website name. So I can put the service in the web application. Took me awhile to figure that out.
Perhaps the web application can start the web service, and the service will wait for the date and time to start doing its thing via timer.
So on to my first Windows Service. It's new to me and very frustrating. I just got the base code to work, the framework, so now it
Self Installs
Self Uninstalls
Creates an Event Log
Writes to the Event Log
Connects to the service controller
net start
net stop
net pause
Writes the event log registry entry, and message id file to connect to.
WOW, that was a mind bender. There's help out there, but it's so generic.
Now I know why many said write a console app.
Well now I can go on to writing the job code, and then figure out how to write an id system dll for the event log id's and messages, and register that file.
So I'm going to try reading my config file in the web app first, and see if I can read it, if so I'm on my way to more frustration.

I am trying to select menu Items if based on url. below is my code and its not working, Please help
Dim strFilePath As String = Me.Context.Request.FilePath
If (strFilePath.Contains(strFilePath.IndexOf("/Groups.aspx").ToString)) = True Then
Menu2.Items(0).Selected = True
ElseIf (strFilePath.Contains(strFilePath.IndexOf("/Reports.aspx").ToString)) = True Then
Menu2.Items(2).Selected = True
Menu2.Items(0).Selected = False
Else : Menu2.Items(0).Selected = False
End If

IndexOf[^] returns a number. You are checking whether the string contains that number. I think you want to check whether the string contains the substring.

Here is my adjustments but it still not working
Dim strFilePath As String = Me.Context.Request.FilePath
If (strFilePath.Contains("/Groups.aspx")) = True Then
Menu2.Items(0).Enabled = True
ElseIf (strFilePath.Contains("/Reports.aspx")) = True Then
Menu2.Items(2).Enabled = True
Menu2.Items(0).Enabled = False
Else
Menu2.Items(0).Enabled = False
End If

What does "not working" mean?
There are only 10 types of people in the world, those who understand binary and those who don't.

So what happens when you step through the code?

it will go to the correct if to enable the items however Item is not enabled on UI
|
|
|
|

Add in some code to set the backgroundcolor of the control you're manipulating; that way you can check easily whether or not you're talking to the correct control, and whether all other code works.
If it does, then there's a chance that the "enabled" property is being reset or overwritten by another part of the code.

One thing to be aware of. You're doing a case sensitive comparison of a string there. What happens if the case doesn't match what you're testing for (hint, you won't trigger any of your enable conditions)?

put it in the PreRender funtion
protected void Page_PreRender(object sender, EventArgs e)
{
Menu mymenu = (Menu)Form.FindControl("Menu1");
MenuItem mi = mymenu.FindItem("Programs");
mi.Selected = true;
}

how can I convert string ('1213,1415') to XML like this:
<planyears>
<planyear>1213</planyear>
<planyear>1415</planyear>
</planyears>
|
|
|
|
|
|
It is as simple as reading alphabets,
static void Main(string[] args)
{
string strInput = "('1213,1415')";
strInput = strInput.Trim(new char[] { '(', '\', ')' });
IList<string> strings = strInput.Split(',');
//Generate the XML
XElement planyears = new XElement("planyears");
foreach (string str in strings)
{
planyears.Add(new XElement("planyear", str));
}
}

Hi,
i have a problem for making rfid program with socket in c#.
i try this code :
socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.IP);
IPAddress[] ip = Dns.GetHostAddresses(ipLoc);
IPEndPoint ep = new IPEndPoint(ip[0],23);
socket.Connect(ep);
Console.WriteLine("Connected");
char open1 = (char)13;
char open2 = (char)10;
//char[] myArray = new char[] { open1, open2 };
Byte[] sendBytes2 = Encoding.ASCII.GetBytes(Convert.ToString(open1));
Byte[] sendBytes = Encoding.ASCII.GetBytes(Convert.ToString(open2));
//Byte[] sendBytes2 = Encoding.ASCII.GetBytes("10");
//socket.Send(sendBytes);
socket.Send(sendBytes2);
socket.Send(sendBytes);
count = socket.Receive(buffer);
Console.WriteLine(System.Text.Encoding.ASCII.GetString(buffer, 0, count));
//socket.Shutdown(SocketShutdown.Both);
socket.Disconnect(true);
socket.Close();
but i not have a result.. rfid card not read in console and gate cannot to open..
i hope all of you can help my problem..
thanks very much..
