Enabling Write Access to A folder in IIS



Issue
Sometimes in web development, we may want to grant WRITE access to a folder probably for file upload purposes or mostly in my own case, PDF file generation purposes. The challenge however, is that all folders are read only which means your application will always throw errors whenever you attempt a write operation.

 Solution
  1. Locate the folder in windows explorer
  2. Right click on the folder and select properties
  3. In the securities tab, click edit, then click add in the new dialog box that shows up
  4. Type IIS AppPool\ApplicationPoolName (you need to replace ApplicationPoolName with the name of the application pool in IIS that your web app is running under)
  5. Click Check Names to resolve the name, then click Ok 
  6. Under permissions for ..., check Modify under allow. 
  7. Click Ok on all dialog boxes


 Note
Some people will grant Modify or Full Control right to Everyone for the folder, note that this posses a huge security risk and should never be your approach to resolving the issue

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
