When posting your question please:- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode HTML tags when pasting" checkbox before pasting anything inside the PRE block, and make sure "Ignore HTML tags in this message" check box is unchecked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question in one forum from another, unrelated forum (such as the lounge). It will be deleted.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
When answering a question please:
- Read the question carefully
- Understand that English isn't everyone's first language so be lenient of bad spelling and grammar
- If a question is poorly phrased then either ask for clarification, ignore it, or mark it down. Insults are not welcome
- If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid.
cheers,

I have requested on Ionic's Ionicons GitHub repository to add icon of Basket and/or Hamper.
Instead of Cart icon, Basket or Hamper icon is more appropriate for food items in e-commerce.
Request: New icon > Basket or Hamper · Issue #412 · driftyco/ionicons · GitHub
So, please vote it up  if you are also agree.
(BTW, (if you are not aware) Ionicons can be used in mobile as well as in web applications (and on desktop app too).)

I'm investigating and exploring what technology to recommend for our development team's mobile application development. I have previous experience using Xamarin.Android (but not Xamarin.Forms), and my manager has previous experience with Telerik Platform (but not NativeScript).
As a team we're full stack ASP.NET developers so have experience with C#, HTML, CSS and Javascript.
We're looking to build fairly straight-forward apps with limited use of the device's capabilities in the future (e.g. the camera). The apps we have are currently responsive web pages but we want to start using some of the device features hence why we want to write apps.
From my own explorations thus far.
Xamarin.Forms
Pros
- Uses C# which we are already familiar with
- I have previous experience with Xamarin.Android
- It's part of Visual Studio
- It has great integration with the .NET ecosystem
Cons
- You need to write separate code for all device specific functionality
- You need to download and install the Windows Phone emulators to develop for the Windows Phone (which has thus far failed on my dev PC as I need to enable virtualisation in my BIOS)
- You need a Mac to develop for iOS
At the time of writing I have only managed to get a basic Android device running in the VS IDE
Telerik NativeScript
Pros
- Uses XML, Javascript (Node.js) and CSS which we are already familiar with
- One codebase for all mobile platforms
- Access to the NPM ecosystem of modules
Cons
- No support for Windows Phone (although Telerik have stated that this will be addressed in a future release)
I really like Xamarin.Forms but so far Telerik NativeScript seems easier to use with some great debugging tools and clean and consistent UI.
I've been looking into both tools over the last few days and they both have their pros and cons, so I'd appreciate any thoughts from others who may have ideas, suggestions, thoughts etc.

Thanks for this, it's really useful. I'm currently looking into different types of mobile responsive development and design. Would be interested to know what you think of this articleI found online.
I am new to the world of app development, do you agree with the fonts recommended that are recommended in the above article?

What's the best way designing animated web content for a mobile friendly website?
|
|
|
|
|
What sort of animations? Simple animations on the web page can be performed using jQuery (or JavaScript itself). Even CSS can do these things, such as animating the elements and their properties of view. JavaScript Animation[^], Using CSS animations - CSS | MDN[^].
If you somehow want to run animations that are other than simple ones like HTML element based animations, then OpenGL would be where you should go. Most of the browsers support it, Three.js[^] is also one of such framework which support animations using JavaScript. But note that however you write, whichever framework you support, JavaScript is based on an engine that interprets the script and runs it, and that is going to take a lot of CPU power and RAM, so basically JavaScript would be a monster eating: 1) CPU, 2) RAM, 3) Battery. If your animations are promising, don't worry about these.

This is my first attempt evet at Xamarin or Mobile Apps. Using VS2015 Enterprise on Win 7.
I'm following this page[^].
I select Blank App (Xamarin.Forms.Portable) and click OK. It then starts creating 4 projects.
- I get prompted to connect to a Mac. No.
- I get prompted for the target (Win 10 is the only choice)
First Issue
I get the message "A problem was encountered creating the sub project 'App1.Windows'. This project requires a Visual Studio update to load. Right-click on the project and choose "Download Update"."
VS is still busy creating things so I can't click Download Update yet so I click OK
VS finishes creating things.
Second Issue
I look for "Download Updates" on the Windows project - it's not there
All 4 projects are there - PCL, Droid, iOS, and Windows. So I try to compile.
Third Issue
Now the fun begins. I get 37 compilation errors, all in the Android project.
There are a bunch of thses:
"Download failed. Please download https://dl-ssl.google.com/android/repository/android_m2repository_r22.zip and put it to the C:\Users\Me\AppData\Local\Xamarin\Xamarin.Android.Support.Design\23.0.1.3 directory.
There are a bunch of "Please install package...." messages - When I go to NuGet, they're already installed.
I also get a bunch of "The remote server returned an error: (407) Proxy Authentication Required." errors.
All I did was try to create the projects? Any ideas on what's wrong?

Have a look at the Android SDK manager and try removing and re-installing the API 23 stuff, and make sure the Preview Channel stuff is firmly in the bin where it belongs. For the X86 emulators, you'll need HAXM, which doesn't update itself so grab the latest version from Intel to make sure (my VS 2015 installation added HAXM 1.0 which isn't good enough, it demands V 6.0 IIRC).
For the "download required" problem, have a look here: c# - “This project requires a Visual Studio update to load” error when creating a Xamarin.Forms Cross-Platform Application - Stack Overflow[^] - the Marakai solution may help.
It's all a bit flaky and rushed, I think.

If it doesn't fix it, then give me a shout tomorrow when I've got the PC on, and we'll see what the differences between our two setups are.

OK, so I opend the SDK manager and removed them... um, how do I now reinstall them? THE SDK manager doesn't seem to have a way to do that?

Tick them - the "Install 'n' Packages" button will be enabled.

My SDK looks like this[^]
Except, the Install Check Box is already checked when the SDK opens. The Install button is disabled. Everything listed is already installed. There are no items marked "Not Installed".

No, I was just confirming with you that what I have is the correct SDK manager. My SDK app looks like the one I posted, except I have no packages to be installed.
I just restarted it as Admin and same thing.

Addendum: did you run the SDK manager in Admin mode? If not, it'll fail to update (or mine does)

Been onto something else for the last few days. I want to again try to get this working. I have your email address so we can exchange pics if needed.
I would appreciate your help.

OK - today isn't the best day - I'm in and out a lot - but lets see what we can do.

OK, I recreated the project as I did in my original post. Same issues as I posted then..
I emailed you a pic of the SDK Manager.
In Visual Studio, when I compile, I get
