Windowservice error

Question

I have solution which contain so many projects and windowservices. I modified coding on the application side of windowservice,after that i copied the exe regarding that service

Answer 1

We create many services during our work and one method for debugging I've found very useful is the following:

Make your service a "dual application" that can run as a service or as a normal Windows Forms application, controlled by some command line parameter. I pass "/gui" to my services.

In void Main(string[] args) I check for the parameter:

If it is missing, I execute the code to instantiate the service (the code generated by Visual Studio).

If it is there, I run code to create a normal Windows Forms application, where the main form instantiates the service and calls OnStart and OnStop accordingly (you'll have to create wrapper methods due to visibility of OnStart and OnStop).

Of course you have to add the references to the Windows Forms assemblies manually and add code like Application.Run(...) yourself, but debugging capabilities are greatly improved without going through the hassle of the "Stop Service, Copy File, Start Service, Fail"-routine.

Most likely, there's a bug in your OnStart code which makes the instance drop out of that routine and the service manager keeps waiting.

EDIT
Here's a code sample for you of the way I create the service/gui depending on the parameter:

static void Main(string[] args)
{
    if (args.Length > 0 && args[0].Equals("/gui"))
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new FrmGui());
    }
    else
    {
        ServiceBase[] ServicesToRun;
        ServicesToRun = new ServiceBase[] { new SampleService() };
        ServiceBase.Run(ServicesToRun);
    }
}
