Adding Quartz to your ASP.NET Core

This is a ready made example of how to add a scheduled job to your ASP.NET core web application:

    public class YourJob : IJob
    {

        public static async void Start() {
            IScheduler scheduler = await StdSchedulerFactory.GetDefaultScheduler();
            await scheduler.Start();

            IJobDetail job = JobBuilder.Create<YourJob>().Build();

            ITrigger trigger = TriggerBuilder.Create()
                .WithDailyTimeIntervalSchedule(s =>s.WithIntervalInSeconds(10))
                .StartNow()
                .Build();

            await scheduler.ScheduleJob(job, trigger);
        }

        Task IJob.Execute(IJobExecutionContext context) {
            return Task.Run(() => {
                Program.Counter++;
            });
        }
    }

public class YourJob : IJob

{

public static async void Start() {

IScheduler scheduler = await StdSchedulerFactory.GetDefaultScheduler();

await scheduler.Start();

IJobDetail job = JobBuilder.Create<YourJob>().Build();

ITrigger trigger = TriggerBuilder.Create()

.WithDailyTimeIntervalSchedule(s =>s.WithIntervalInSeconds(10))

.StartNow()

.Build();

await scheduler.ScheduleJob(job, trigger);

}

Task IJob.Execute(IJobExecutionContext context) {

return Task.Run(() => {

Program.Counter++;

});

}

In your Program.cs

        public static int Counter = 0;

        public static void Main(string[] args)
        {
            var host = BuildWebHost(args); 

            YourJob.Start();
            host.Run();
        }

public static int Counter = 0;

public static void Main(string[] args)

{

var host = BuildWebHost(args);

YourJob.Start();

host.Run();

}

How to use - (dash) in the ASP.NET MVC call?

ActionName attribute can be used:

[HttpGet]
[ActionName("edit-details")]
public ActionResult EditDetails()
{
    return View("EditDetails", new ModifyViewModel());
}

[HttpGet]

[ActionName("edit-details")]

public ActionResult EditDetails()

{

return View("EditDetails", new ModifyViewModel());

}

Footer from database in MVC ASP.NET

I've been struggling for a while to find a sensible way of getting the footer. Well... This is where partial views come useful. There are several ways to solve this problem. I've created a controller:

public class _OtherController : Controller
{
    Models.DBEntities _db = new Models.DBEntities();

    [ChildActionOnly]
    public ActionResult _Footer()
    {
        Footer viewModel = new Footer();
        return PartialView("_FooterPartial", viewModel);
    }
}

public class _OtherController : Controller

{

Models.DBEntities _db = new Models.DBEntities();

[ChildActionOnly]

public ActionResult _Footer()

{

Footer viewModel = new Footer();

return PartialView("_FooterPartial", viewModel);

}

In the Shared folder I've added _FooterPartial.cshtml and in the layout this line:

@{Html.RenderAction("_Footer", "_Other");}

1	@{Html.RenderAction("_Footer", "_Other");}

It worked so awesome.

Razor with JavaScript

Today I had a problem of adding markers onto a google map. I didn't really want to create a service to handle the request and return an array. So instead I tried doing something simpler.

@foreach(var pins in Model.Pins) {
   {latLog: [@Html.DisplayFor(item => pins.Lat), @Html.DisplayFor(item => pins.Log)], data: '@Html.DisplayFor(item => pin.Name'},
}

@foreach(var pins in Model.Pins) {

{latLog: [@Html.DisplayFor(item => pins.Lat), @Html.DisplayFor(item => pins.Log)], data: '@Html.DisplayFor(item => pin.Name'},

}

This obviously didn't work. Razor was getting confused; it didn't know which one was the script and which one

MVC File Upload - Access to the path is denied

An interesting problem occurred yesterday when I was trying to upload a file to the server. I was getting: Access to the path '' is denied The problem wasn't actually caused by the file upload but by my attempt to create a directory to put that file there. After reading a bunch of answers on

How to display an image on the website from a binary source (e.g. a database)

There are various ways in which one could display an image on the website form a binary source. One solution would invole simply converting the binary source into a base64 and put it as the src of the image:
