Failed to load resource: the server responded with a status of 404 (WebResource.axd)

-
I downloaded a GridView custom control with cool features on search and filtering that was developed on Visual Studio 2010 and ASP.NET 4.0. After playing around with the control, I decided to migrate the files to Visual Studio 2012 ASP.NET 4.5. Upon running the ASP.NET Project, the resource to be embedded on the GridView control in which case a JavaScript file was not recognized/found. And thus, returned a 404 status. After doing some research, I came up with the solution below.

Steps to fix the issue:
1. Set Build Action of the Resource/JavaScript file to Embedded Resource. In my project, the file to be embedded is EnhancedGridView.js
2. Add WebResourceAttribute to the GridView custom control to embedded a JavaScript file as Resource in an assembly. Make sure that the namespace of the file is correct.

[assembly: WebResource("GridViewFilter.EnhancedGridView.js", "text/javascript")]
public partial class EnhancedGridView : GridView
{
   //.....
}
3. In the control's PreRender event, I updated the namespace of where the JavaScript file is located. In my app, it's GridViewFilter which is the Root namespace.

    ClientScriptManager cs = this.Page.ClientScript;
    cs.RegisterClientScriptResource(typeof(CustomGridView), resourceName);
}

Good Day Gents! During this free-time I started setting up Node.js on my machine as part of my career goals which is learning new frameworks in preparation for new projects. So the first thing I did was to install TypeScript language to get myself familiar with Angular 2+. After I finished setting up TypeScript, I then created a simple HelloWorld program and ran the application through Visual Studio Code using the "tsc: build - tsconfig.json" command. I encountered an error which says "The term 'tsc' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again." Below are the details on my machine and packages installed:   - Operating System: Windows 10 Pro   - Node.js: 14.16.0   - npm version: 6.14.11   - Typescript: 4.2.3 (using command: "npm install -g typescript") After doing some research and reading th...

Invalid nested tag div found, expected closing tag input

-
Hello all, I've been experimenting on how to print html document using the said 3rd party software called iTextSharp . iTextSharp is a popular tool and has several examples on the internet regarding integration to the project and occurring issues. One of the issue I encountered is Invalid nested div tag and is expecting a closing tag input . As I trace back my html source, the tags are well-formed except that they are self closing tags such as <input>, <hr>, <img>, <br> or the like. These tags when passed to an action method as string are not properly closed and thus an issue is thrown by iTextSharp's XMLWorkerHelper's ParseXHtml() method. <img src= "~/Images/success.png" /> <input type= "hidden" name= "OrderStatusHTML" /> <input type= "submit" id= "btnSubmit" value= "Export to PDF" class= "btn btn-success" /> The solution I came up with is to fi...
