Posting Data To WebBrowser Control In C#

-
Good day!

Basically, it is possible to post data to web browser control using C#. The code below, was referenced from MSDN, but i slightly modified some of it's functionalities. 
string url = "http://example.com";  
string postData = String.Format("city=DC&Page={0:00}",pageNum);  
byte[] Post = Encoding.UTF8.GetBytes(postData );  
string AdditionalHeaders = "Content-Type: application/x-www-form-urlencoded";  
//wbSample is the web browser control  
//the WebNavigate method is just a simple method i created  
//which simply assigns url to the browser, the post data and additional headers  
WebNavigate(wbSample , ListURL, "", Post, AdditionalHeaders);

Good day to all! Here's an example of a WPF CRUD (Create,Update and Delete) project using the DataGrid control, ADO.NET Entity Framework 6.x, C#.NET and Model–View–Viewmodel(MVVM) architectural pattern.

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...
