I have problem to create running leds with Raspberry PI 3 Windows IOT, but random led blink does work.
The code for both are almost the same, only diffrent runnings leds is controlled by variable count and random led
is generated with random generator.
The running led code is below this text. I will get only the first led to light, and rest of leds stays dark. Can someone see what's wrong with this code?
But the random blink led works, which comes after this running leds code and both codes almost identically, but still the running leds code does not work.

How to redirect to a default page when connected to a server from a browser?
|
|
|
|
|
I don't see anything urgent, nor do I see a proper question.
|
|
|
|
|
im doing my project!! so i wanted to know how to redirect to a particular page through the browser when connected to a server.
|
|
|
|
|
No, I checked with my boss and he said it's not urgent at all.
This isn't any more of a question than your vague posting in QA. There isn't any need to cross post all over the place. And, "I'm doing my project" means nothing to us and isn't an answer to question that anyone has asked you so far.
|
|
|
|
|
how will your boss decide if its urgent or not?? its urgent for me.
|
|
|
|
|
We are all volunteers here, so saying something is urgent means nothing to us. Please learn to post proper questions, and stick to one forum only.

We are unpaid volunteers and no one cares how urgent you think it is, because it's not urgent to anyone but you.

Not sure how this is related to mobile development, but...

In IIS switch to Features View and open Default Document. Then click add and put in your default document.

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.
"There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." - C.A.R. Hoare

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?
