Post Data to ASP.NET Page From PHP or Javascript



Background:
For most PHP developers, the technique of posting data from one page to a different page is not a difficult thing. In fact, in PHP development, this technique is learnt by beginners. In ASP.Net however, it doesn't work the same way. The ASP.Net platform is designed to implicitly post data to itself and developers need not manually trap posted data themselves.

Issue:
This simplistic development approach implemented by ASP.Net poses a problem where one needs to for one reason or the other, post to the ASP.Net page from another ASP.Net page, a PHP page, from JavaScript or even Python, ruby, and any other server side platform you can imagine. In my own case, I was using dropzone.js to implement drag-and-drop file upload for an application. I would have to post to a server side platform using JavaScript. For some reasons, I didn't want to use PHP, even though PHP would work seamlessly. The platform available for me was ASP.Net, but remember; ASP.Net doesn't allow unsolicited posting of data to its pages! or so I thought.

Solution:
ASP.Net actually allows posting of data like PHP does, and one could actually develop with ASP.Net as if it were PHP using <form action="somepage.aspx" runat="server" method="POST">. I have the VisualStudio environment too thank for this breakthrough. After searching the web for a full day without much progress, I resorted to trial and error. The VisualStudio IDE gives lots of explanations for programming elements through its powerful intellisense. The Page.Request property exposes lots of useful members with which you may interact with the current request to your page.

Instances:
In order to access request headers use: Request.Headers["header_name"]
In order to access files posted use: Request.Files
In order to access form data use: Request.Form.Get("data_name")
You may also return data to the calling platform using Response.Write("some data")

What a breakthrough!

Resize or Crop Image before Upload Using HTML5 File API

I've always loved how Whatsapp, Facebook, Twitter and all the major social network platforms maintained sanity of uploaded profile pictures through the use of instant resize at upload time. Of course not only profile pictures need to be made to conform to a specific dimension, if you find other scenarios during development when you need to ensure that your images are of a specific height and width, or aspect ratio then this article will help you do just that. You may also just want to give the user ability to resize before final upload, this article will help you do just that. Step 1: Download CropperJs Plugin There are lots of plugins that could help to achieve our objective, and I've tried a few. I find this one very robust and easier to use. Here's the github link Step 2: Import the CropperJs Plugin Using your script tag, import the downloaded plugin's Javascript file and link the CSS file too. Note, that for speedy loading, CSS files should be loaded in t

Get Creative With Data Tables: Row Click Events

Introduction Datatables from datatables.net are so lovely, especially with the responsive extension that you can enable by including dataTables.responsive.js in your project. I particularly find fascinating the combination of search / filtering, pagination, ordering and exporting features which are available right 'out-of-the-box'. Issue Well, as great as datatables are, you will find it difficult if not impossible to develop a system with acceptable user-experience using bare-bone datatables implementation. In my own case, because I was porting my superb Asset and Inventory Management Application found at asset.bz to the mobile platforms using PhoneGap, I needed the user to be able to tap on any record in order to perform some pre-define operations like editing, approvals etc. Solution Apparently, the solution isn't far fetched. The sample code below would do the job nicely: // HTMLTableData is your array of records to be displayed in the data table

Exception from HRESULT: 0x80131040

Background: I just recently upgraded to Windows 10, and I must confess, the overall experience immediately got me. I love the fact that our good old start menu was back and better. The tile one was much of a controversy although I have been indifferent about it all the while. I particularly love Cortana, the search assistant who made me remember the office assistants that used to come with the office suite back then. The euphoria I experience was a perfect disguise, however, for the ambush that was ahead. Issue: I went ahead to open VisualStudio and launched the project I was currently working on. I pressed F5 to launch it, only to ram into a jam! The project I still successfully tested only a day before now threw an exception. From my experience, and this situation hasn't proved me wrong, every Microsoft upgrade always has a catch somewhere. This particular one forced me to begin to rectify a fault in an application that was initially 'bug-free' before my u
