Generate QR Code using Asp . net Core - Download Source Code
20 Apr 2019 ... Generating QR Code using Asp . net Core . There are many components available for C# to generate QR codes , such as QrcodeNet, ZKWeb.

Although ideally our code will run without any unpleasant surprises, there s always a possibility that something might go wrong when processing client requests. In the context of a live web application, errors can happen unexpectedly for various reasons, such as software failures (operating system or database server crashes, viruses, and so on), hardware failures, or even bad or unexpected input user data. The best strategy to deal with these unexpected problems is to implement error-handling mechanisms that intercept the errors and handle them appropriately. And here we ll meet exceptions. Exceptions represent the modern way of intercepting and handling runtime errors in object-oriented languages such as C#. When a runtime error occurs in your code, the execution is interrupted, and an exception is generated (or raised). If the exception is not handled by the local code that generated it, the exception goes up through the methods in the stack trace. If it isn t handled anywhere, it s finally caught by the .NET Framework, which generates an error message. If the error happens in an ASP.NET page during a client request, ASP.NET displays an error page, eventually including debugging information, to the visitor. (The good

private void button1_Click(object sender, EventArgs e) { Employee emp = new Employee(); EmployeeDetails ed= emp.GetEmployee(int.Parse(textBox1.Text)); label7.Text = ed.EmployeeID.ToString(); label8.Text = ed.FirstName; label9.Text = ed.LastName; label10.Text = ed.HomePhone; label11.Text = ed.Notes; } The Configure() method of the RemotingConfiguration class is called in the Load event handler of the form. This method is the same as the one we called in the console application. The code passes the full path of the client configuration file to the Configure() method. This call is needed just once and hence it has been put in the Load event and not in the Click event of the Show button. Inside the Click event handler of the Show button, a new instance of the Employee class is created. Then the GetEmployee() method of the Employee class is called by passing the supplied employee ID. The GetEmployee() method returns an object of type EmployeeDetails. The details such as EmployeeID, FirstName, LastName, HomePhone, and Notes are then displayed in labels.

news in this scenario is that ASP.NET can be instructed to display a custom error page instead of the default one you ll do that by the end of the chapter.) On the other hand, if the exception is dealt with in the code, execution continues normally, and the visitor will never know a problem ever happened when handling the page request. The general strategy to deal with runtime exceptions is as follows: If the error is not critical, deal with it in code, allowing the code to continue executing normally, and the visitor will never know an error happened. If the error is critical, handle it partially with code to reduce the negative effects as much as possible, and then let the error propagate to the presentation tier that will show the visitor a nice-looking Houston, we have a problem page. For the errors that you can t anticipate, the last line of defense is still the presentation tier, which logs the error and politely asks the visitor to come back later. For any kind of error, it s good to let the site administrator (or the technical staff) know about the problem. Possible options include sending details about the error to a custom database table, to the Windows Event log, or by email. At the end of this chapter, you ll learn how to send an email to the site administrator with detailed information when an error happens. In our data access code, you ll consider any error as critical. As a result, you ll minimize potential damage by closing the database connection immediately, logging the error, and then letting it propagate to the business tier.

Note The business logic you see in the business tier code can control which exceptions pass through it. Any exception generated by the data access code can be caught and handled by the business tier. In case the business tier doesn t handle it, the exception propagates to the presentation tier, where it s logged once again (so the administrator will know it was a critical error), and the visitor is shown a nice error message asking him to come back later.

Note If you look at the code that consumes the remote server, you won t find anything different. This is
