Hi Erik;
To save ya having to buy a book from a rather cheeky author :
The answer so far as I can see is that you create a service controller in
your Windows / Taskbar / Web page app and then you call
ServiceController.CustomCommand - This passes a command directly to the
service with one parameter. Anyhow here is some code that I just put
together and it seems to work just fine and looks to be the "official" way
to do it.
The steps I did were -
create custom service
override onCustomCommand
add installer class to the code ( took me ages to find this out)
install service by running installutil against the exe.
write windows app
drag service name from server explorer onto the form - this creates service
controller
call servicecontroller.Executecommand(parameter)
NB parameter must be >127 or it gives an exception (took ages this too!)
Hope it helps,
and sorry for the huge legal message that gets attached :)
Jim
CODE FOLLOWS:
In the Service :
protected override void OnStart(string[] args) {
SomeLogFunction("Service Running");
SomeLogFunction("Start");
}
protected override void OnStop() {
SomeLogFunction("stop");
}
protected override void OnCustomCommand ( int theCmd ) {
SomeLogFunction("OnCustomCommand");
SomeLogFunction("Doing lots of custom stuff");
SomeLogFunction("Command was "+theCmd);
}
In A Windows Application :
// This was created by dragging the name of the service in the server
explorer onto the form
private System.ServiceProcess.ServiceController serviceController1;
private void button1_Click(object sender, System.EventArgs e) {
SomeLogFunction("Button1::SendCustomCommand");
if (serviceController1.CanStop) {
SomeLogFunction("can stop srv");
}
serviceController1.ExecuteCommand(150);
}
Installer Class To Get Install to work (pasted into service code):
[RunInstaller(true)]
public class ServiceRegister: Installer {
private ServiceInstaller serviceInstaller;
private ServiceProcessInstaller processInstaller;
public ServiceRegister() {
// define and create the service installer
serviceInstaller = new ServiceInstaller();
serviceInstaller.StartType = ServiceStartMode.Manual;
serviceInstaller.ServiceName = "AMyService";
//ServiceControl.ServiceControlName;
serviceInstaller.DisplayName = "A Descrpttion";
//ServiceControl.ServiceControlDesc;
Installers.Add(serviceInstaller);
// define and create the process installer
processInstaller = new ServiceProcessInstaller();
#if true //RUNUNDERSYSTEM
processInstaller.Account = ServiceAccount.LocalSystem;
#else
// prompt for user and password on install
processInstaller.Account = ServiceAccount.User;
processInstaller.Username = null;
processInstaller.Password = null;
#endif
Installers.Add(processInstaller);
}
}

Subject: [DOTNET] UI for Windows service
I have a windows service which I'm trying to write control code for. What I
want is to put an icon in the system tray, and have a context menu on the
icon. Then, when the user selects a menu item, either a form is shown, or
some action is taken, depending on the menu item selected. I have a problem,
and a couple of questions.
My problem is that I can't seem to get any events handled from the
NotifyIcon. In the OnStart method, I create a NotifyIcon, and add a onclick
handler. In the click handler, I add a simple MessageBox.Show("click"). I
compile the service, add it with InstallUtil, and set the "Allow Service to
Interact with Desktop" option in the control panel. I start it up, and the
NotifyIcon appears correctly, but I can't get anything in the event handler
to run. I've tried a number of variations, all with no luck. I've searched
all over the net, and found people with this same problem, but no solutions.
What am I doing wrong?
My questions are related to managing the service. I want to have a fairly
complex form to manage the service, which is started from the context menu.
Should I put this form in a completely different assembly then the service,
and/or call it from a different thread? What is the best practice of writing
Windows services, and the UI that controls them?
If anyone has an example project doing I'm working on, that would be very
helpful.
Thanks,
Erick
