How To Generate QR Code Using ASP . NET - C# Corner
24 Nov 2018 ... This blog will demonstrate how to generate QR code using ASP . NET . Create an empty web project in the Visual Studio version of your choice. Add Web Form, right-click on the project, select Add New Item, choose web form, give it a name and click on Add. Add script and styles in web form head section.

The same applies to URLs used by <jsp:include>, the <%@ include %> directive, the <%@ taglib %> directive, and methods that create RequestDispatcher objects The rule for interpreting these relative URL s is this: I If the URL begins with /, it s interpreted as being relative to the application root directory I If it doesn t begin with /, it s interpreted as being relative to the current JSP page This brings up a subtle difficulty, however URLs in a JSP page used as hyperlinks, form actions, style sheet links, or image sources are interpreted by the browser, not the server If the LyricNote home page is a JSP page with a link to /products/contest/ rulesjsp, the link cannot be hardcoded with the products application name Why not Because the application name isn t necessarily going to be products This depends entirely on where the system administrator chose to install the Web application It could have been mounted as product_test or staging_area or anything else Only when the application is actually running can a JSP page know the name, which can be obtained from the requestgetContextPath() method

Strictly speaking, the portion of the URL that constitutes the Web application name can be a multilevel string like /products/test/Wednesday, but it s more common for a single token to be used The <servlet-mapping> element of the deployment descriptor can be used to map any URL substring to a particular servlet Shown here are the default mappings

You can get around this in several ways The JSP page can write every URL as a JSP expression concatenating requestgetContextPath() with the rest of the URL, but this gets to be tedious and clutters up the code unnecessarily A more elegant approach is to use the HTML <BASE> element to assign a context to the page:

<HTML> <HEAD> <BASE HREF= http://wwwlyricnotecom/products/ > </HEAD> <BODY> <A HREF= contest/rulesjsp >View the contest rules</A> </BODY> </HTML>

With the <BASE> statement, the Web browser can interpret any nonabsolute URLs relative to the HREF attribute Thus, contest/rulesjsp becomes http://wwwlyricnotecom/products/contest/rulesjsp Of course, you aren t done yet You still need to figure out the BASE HREF at run time The HREF attribute needs to be a complete URL, not just an absolute path from the server, so you need a number of details The URL may start with https, if the connection uses SSL A port number may exist, not just the default port 80 Fortunately, the request object can provide all this information The following scriptlet solves the problem in a general way

<% String String int String scheme server port path = = = = requestgetScheme(); requestgetServerName(); requestgetServerPort(); requestgetContextPath();

Dim xml As XElement = XElement.Load("..\..\People.xml") Dim query = From p In xml.Elements("person") _ Where p.Element("id").value = 1 _ Select p For Each Dim record In query Console.WriteLine("Person: {0} {1}", _ record.Element("firstname"), _ record.Element("lastname")) Next

StringBuffer sb = new StringBuffer(); sbappend(scheme); sbappend("://"); sbappend(server); if ((port != -1) && (port != 80)) { sbappend(":"); sbappend(port); } sbappend(path); sbappend("/");

Within a Web application, servlets and JSP pages can share data and functionality through a common object known as the servlet context This is an object that implements the javaxservletServletContext interface The servlet context serves a number of useful purposes: I Object sharing Both servlets and JSP pages can store objects by name in the servlet context, so they can be retrieved by other servlets and JSP pages These bindings persist as long as the application is active I Initialization parameters Constants used throughout the application can be specified in the deployment descriptor and accessed through methods in the servlet context This permits configuration details such as database URLs and driver class names to be specified outside any compiled Java code I Request dispatching Servlets can forward requests to other servlets and JSP pages or include their output in the current output stream The servlet context provides methods for creating request dispatchers using either a path or a servlet name I Message logging The servlet context has access to the servlet log and can be used to write messages in a vendor-independent way See Table 4-8 for a complete description of the methods provided by the servlet context In a JSP page, the servlet context object is automatically available in the application implicit variable In a servlet, it can be obtained with the getServletContext() method

Described so far is the run-time structure of a Web application For deployment, this structure must be collapsed into a single file called a Web archive (war) file This is nothing more than a jar file with a different extension (war), whose top level corresponds to the root of the Web application To use a concrete example, consider the products Web application, shown in Figure 18-2 Its root directory contains an indexjsp file and four content
