Using ASMX webservices with HttpWebRequest in c# 4.0

If you want to call a .NET 4.0 C# web service, without using the WSDL or “Add Service Reference” in Microsoft Visual Studio 2015, you can use the following functions written in c#:

/// <summary>
/// Execute a Soap WebService call
/// </summary>
public override void Execute()
HttpWebRequest request = CreateWebRequest();
XmlDocument soapEnvelopeXml = new XmlDocument();
soapEnvelopeXml.LoadXml(@"<?xml version=""1.0"" encoding=""utf-8""?>
<soap:Envelope xmlns:soap="""" xmlns:xsi="""" xmlns:xsd="""">
<HelloWorld3 xmlns="""">
using (Stream stream = request.GetRequestStream()) 
using (WebResponse response = request.GetResponse())
using (StreamReader rd = new StreamReader(response.GetResponseStream())) 
string soapResult = rd.ReadToEnd();
/// <summary>
/// Create a soap webrequest to [Url]
/// </summary>
/// <returns></returns>
public HttpWebRequest CreateWebRequest()
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(@""); 
webRequest.ContentType = "text/xml;charset=\"utf-8\""; 
webRequest.Accept = "text/xml"; 
webRequest.Method = "POST"; 
return webRequest; 


<?xml version=”1.0″ encoding=”utf-8″?><soap:Envelope xmlns:soap=”” xmlns:xsi=”” xmlns:xsd=””><soap:Body><HelloWorld3Response xmlns=””><HelloWorld3Result>test</HelloWorld3Result></HelloWorld3Response></soap:Body></soap:Envelope>


You can use complex types in you’re request. I use fiddler to get the contents of the soap envelope.


What’s the difference between a user story and an Epic when it comes to Agile?

They are very generic term actually. There is many way to interpret them, varying in the literature and how people see them. Take everything I say with a huge grain of salt.

It takes a thousand voices to tell a single story

Usually, an Epic comprise a very global and not very well defined functionality in your software. It is very broad. It will usually be broken down into smaller user story or feature when you try to make sense of it and making them fit in an agile iteration.

Solid Software Development Principles

Software development is not a Jenga game.

Single Responsibility Principle
Just because you can, doesn’t mean you should.

Open Closed Principle
Open chest surgery is not needed when putting on a coat.

Liskov Substitution Principle

If it looks like a duck, quacks like a duck, but needs batteries – you probably have the wrong abstraction

Interface Segregation Principle
You want me to plug this in, where?

Dependency Inversion Principle
Would you solder a lamp directly to the electrical wiring in a wall?

How to send Push Notifications using PHP / Google Android

Google Cloud Messaging (GCM) for Android is a service that allows you to send data from your server to your users’ Android-powered device, and also to receive messages from devices on the same connection. The GCM service handles all aspects of queueing of messages and delivery to the target Android application running on the target device, and it is completely free.

The only thing you will need is a Google_Api_key:

To create a Google API project:

  1. Open the Google Developers Console.
  2. If you haven’t created an API project yet, click Create Project.
  3. Supply a project name and click Create.Once the project has been created, a page appears that displays your project ID and project number. For example, Project Number: 670330094152.
  4. Copy down your project number. You will use it later on as the GCM sender ID.

To obtain an API key:

  1. In the sidebar on the left, select APIs & auth > Credentials.
  2. Under Public API access, click Create new key.
  3. In the Create a new key dialog, click Server key.
  4. In the resulting configuration dialog, supply your server’s IP address. For testing purposes, you can use0.0.0.0/0.
  5. Click Create.
  6. In the refreshed page, copy the API key. You will need the API key later on to perform authentication in your app server.

How to upload all files from a folder on Microsoft Azure Storage

If you are working with Microsoft Cloud, you must have had the need to move a few files (in bulk) from a folder onto the Azure Storage System.
To get started, you will need to have a Microsoft Azure Account, create a storage account, get the connection string for it.
If you are unsure about how to proceed, check out this great introductory article: How to use Blob Storage from .NET
This is a demo connection string that you will need to add to your web.config file:
<add key="StorageConnectionString" value="DefaultEndpointsProtocol=https;AccountName=srmd1983;AccountKey=JyUOu3/iv+0UMjzI/PtoHd2JKhKx4SOSSxJcsvVp95isAZH6hKpPs/AQDOPxgVXjTNGWCYCSssgiwVVun0rlWXFgJ6A==" />

In your code, import the needed Microsoft.WindowsAzure.Storage namespace. To add this DLL, install the Azure SDK package for your version of Visual Studio and add the DLL into references.

Imports Microsoft.WindowsAzure.Storage
Imports Microsoft.WindowsAzure.Storage.Auth
Imports Microsoft.WindowsAzure.Storage.Blob

Then you will need to create a method that will do all the dirty work. The files will be uploaded in a subdirectory for each folder (in this case, the subdirectory is generated by the ClientID value).

   1:  Imports Microsoft.WindowsAzure.Storage
   2:  Imports Microsoft.WindowsAzure.Storage.Auth
   3:  Imports Microsoft.WindowsAzure.Storage.Blob
   4:  Imports System.IO
   5:  Public Class Azure
   6:  Shared Function UploadAllFilesToBlob(ClientID As String) As String
   7:  Dim err As String = ""
   8:  Try
   9:  Dim storageAccount As CloudStorageAccount = CloudStorageAccount.Parse( _
  10:  ConfigurationManager.AppSettings("StorageConnectionString"))
  11:  Dim blobClient As CloudBlobClient = storageAccount.CreateCloudBlobClient()
  12:  ' // Retrieve a reference to a container. 
  13:  Dim container As CloudBlobContainer = blobClient.GetContainerReference("uploads")
  14:  '// Create the container if it doesn't already exist.
  15:  container.CreateIfNotExists()
  16:  Dim dir As CloudBlobDirectory
  17:  dir = container.GetDirectoryReference(ClientID)
  18:  '// Create or overwrite the "myblob" blob with contents from a local file.
  19:  Dim path As String = System.Configuration.ConfigurationManager.AppSettings("SavePath")
  20:  Dim di As New DirectoryInfo(path)
  21:  For Each fi As FileInfo In di.GetFiles()
  22:  Dim fileStream = System.IO.File.OpenRead(fi.FullName)
  23:  '      // Retrieve reference to a blob named the same as the uploaded file. If the file exists, it will be overwritten.
  24:  Dim blockBlob As CloudBlockBlob = dir.GetBlockBlobReference(fi.Name)
  25:  '//create or replace
  26:  fileStream.Position = 0
  27:  blockBlob.UploadFromStream(fileStream)
  28:  fileStream.Close()
  29:  fi.Delete()
  30:  Next
  31:  Catch ex As Exception
  32:  err = "Error: " + ex.Message + "<br />" + ex.StackTrace
  33:  End Try
  34:  Return err
  35:  End Function

setInterval not working in iOS 8 – Home Screen Apps Lose Timing Functions After Lock/Wake


If your application is being used as a homescreen web application, you’ll find yourself in a sorry state. Of course, any web app can be converted into a home screen app by the user, so I guess technically this affects anyone making a remote web application. This bug is easily reproduced by simply calling setTimeout(callback, 1) or requestAnimationFrame(callback) via some button or event. When you first open your application, you’ll notice all timing functions are working fine. However if you lock your phone and then unlock to return to your application, you’ll see none of the timing functions can call callbacks anymore. They are simply broken at a native level. There is no reset, no bringing your application back to life, it’s a kill it and restart situation.

These timing functions are crucial to pretty much every other JavaScript framework/library ever made. Definitely head over to Apple as soon as you can, and let them know that you would like to have all of your JavaScript functions, all the time.

Radar Bug Report:


Alternative to setInterval and setTimeout

JavaScript’s setTimeout and setInterval are evil and not precise…

  1. both have a delay of various milliseconds
  2. both are very resource intensive as they execute several times every second.

A new alternative is requestAnimationFrame. it’s less resource=intensive, does not slow down other stuff and it is disabled on page blur.

This makes it the perfect substitute for a modern setTimeout and setInterval.

So I wrote this functions:


This functions use requestAnimationframe to check if the time is passed based on the elapsed Time calculated from The time passed is more precise than the native functions and theoretically less resource intensive. Another advantage/disadvantage(depends) is that the functions are not executed on page blur.

Good for: animations, visual effects

Bad for: timers, clock

Run iPad Web Application Full Page (Bookmark)

Building an iPhone or iPad Web App is not an easy endeavor. However, if you have any experience in HTML 5, Javascript and CSS its a lot easier to accomplish than you would think. Apple has built a lot of tags and templates into the building of there mobile safari browser. I am going to go over many of the things that I have found that have really helped me build my webapp.

Meta Tags Used By Mobile Safari

To make your app full screen when it is added to the iPhone /iPad home screen using the + button on the browser, the below meta tag will remove all buttons and the url bar and will give it the “native” app look that we are going after. To use any of the meta tags below just add them somewhere in your head tag.

<meta name=”apple-mobile-web-app-capable” content=”yes” />

Now when you pinch on the app it will still zoom and scale. Now, native apps will not zoom or scale, so when need to do something to stop that. Luckily Apple has designed a Meta tag to do that also..

<meta name=”viewport” content=”user-scalable=no, width=device-width” />

The last thing that you may notice is when you tug the app up or down it kinda zooms down and you can see the “background” of the browser. Apple has also designed a meta tag to get rid of that. However, you do need to add a tag to your body tag also. Below is an example…


Making Links Open Fullscreen and Not In Safari

Now this was one of the most frustrating problems I had with making my web app in the beginning. If you use…

<a href=”link.html”>Your Link</a>

that tag will take you straight out of your fullscreen app and right into the normal safari, we don’t want that. So the solution to get past this is to use a little bit of Javascript. Now, how we would do this using the Javascript is below…

<a ontouchstart=”window.location=yourlink.html’ “>Your Link</a>

Now some of you familiar with Javascript will see that we are using the ontouchstart instead of onclick. This is a iPhone/iPad only event trigger that will only work on iOS devices. Its a lot smoother on iOS devices but will not work on computers. You can use that event trigger anywhere in your web app. Since onclick takes about one extra second for the device to read, ontouch start is a great asset to have on our side.

IOS7 and above – Show Links in App

if((“standalone” in window.navigator) && window.navigator.standalone){

var noddy, remotes = false;

document.addEventListener(‘click’, function(event) {

noddy =;

while(noddy.nodeName !== “A” && noddy.nodeName !== “HTML”)

{ noddy = noddy.parentNode; }

if(‘href’ in noddy && noddy.href.indexOf(‘http’) !== -1 && (noddy.href.indexOf( !== -1 || remotes))

{ event.preventDefault(); document.location.href = noddy.href; }


Specifying a Webpage Icon for Web Clip

You may want users to be able to add your web application or webpage link to the Home screen. These links, represented by an icon, are called Web Clips. Follow these simple steps to specify an icon to represent your web application or webpage on iOS.

  • To specify an icon for the entire website (every page on the website), place an icon file in PNG format in the root document folder called apple-touch-icon.png
  • To specify an icon for a single webpage or replace the website icon with a webpage-specific icon, add a link element to the webpage, as in:
    <link rel="apple-touch-icon" href="/custom_icon.png">

    In the above example, replace custom_icon.png with your icon filename.

  • To specify multiple icons for different device resolutions—for example, support both iPhone and iPad devices—add a sizes attribute to each link element as follows:
    <link rel="apple-touch-icon" href="touch-icon-iphone.png">
    <link rel="apple-touch-icon" sizes="76x76" href="touch-icon-ipad.png">
    <link rel="apple-touch-icon" sizes="120x120" href="touch-icon-iphone-retina.png">
    <link rel="apple-touch-icon" sizes="152x152" href="touch-icon-ipad-retina.png">

    The icon that is the most appropriate size for the device is used. If no sizes attribute is set, the element’s size defaults to 60 x 60.

If there is no icon that matches the recommended size for the device, the smallest icon larger than the recommended size is used. If there are no icons larger than the recommended size, the largest icon is used.

If no icons are specified using a link element, the website root directory is searched for icons with the apple-touch-icon... prefix. For example, if the appropriate icon size for the device is 60 x 60, the system searches for filenames in the following order:

  1. apple-touch-icon-76×76.png
  2. apple-touch-icon.png

See “Icon and Image Sizes” for webpage icon metrics.

Now what if your user wants to take a certain element and drag it around with there finger? How are we going to do this? Well the technique that I am using is called Drag Drop Library. Its very simple to use, go to this website, download their javascrupt Library using the green button. Then link to that JavaScript file on any page where you would want to use drag and drop. Now, the syntax for getting an element to be able to be dragged is below…

  • //To make an element draggable
  • var D = new webkit_draggable(‘id_of_element’, {options});
  • //To stop an element from being draggable
  • D.destroy();

So what you are going to do is give an element that you want to be able to be dragged a unique ID using css. Then take that css and input it into the above code that reads ‘id_of_element’. So that sample code would find and html element that has a id=”id_of_element” and make it be able to be dragged around by the users finger. It’s fairly simple and creates an awesome “WOW” affect with your apps.

iPhone and iPad web apps are slowly becoming more wide spread around the world. Especially now that Apple is finally giving us Web Designers and Developers the required tools. Now every iOS developer doesn’t have to be an Obj C wizard and have a mac, any person with a little HTML know how can create easy, good looking apps.

Getting iPad Web App to Work Offline Using Localhost, not Cache-Manifest

I spent so much time looking around trying to figure out how I was going to get my web app to work offline. My client will be using the app at large conferences to showcase there product and give a presentation. Wifi is very very unstable at large conferences so it is necessary to make it work offline. What I finally decided to do was to Jailbreak each iPad, and install a server on the localhost of the iPad. To do that I used a program on Cydia called PHPod. This creates a server on that iPad and gives me access to files stored directly on the iPad. What I did next was SSH into the iPad and copy my entire Web App into the WWW directory. Next, I went to localhost on safari on the iPad, clicked my web app and boom there it is right on the iPad. It runs fast, my JQuery still works, all my forms work, its perfect. Now I am looking to make my own Cydia repo where I can host the web app so that the clients wont have to ssh into the iPad every time there is a change. It will just update the package and the site will be updated by the Repo. Yes there is the option to use Cache Manifest and all that but it doesn’t really work all the time and there’s a limit so I couldn’t cache all my videos and larger files etc.
