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.

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.
In that case you first need to decide which language to use. If you already know Java then go for Android Studio, if C# then you may like to try Xamarin Forms. If you are not experienced in either of these languages then you have a long way to go before you can even start to think about how to build this application. There are lots of articles at Mobile Development[^] which can help.
I'm a long time WPF developer. I am working on a WPF business app for a client and I'm going to be developing an Android tablet app to go with it. This is my first Xamarin Forms project, so bear with me...
So I then decided to convert the project to MVVM. One thing that I found through Googling is that if you want a View Model to open a new page, your View Model has to know about the INavigation property on the Page See this. What concerns me is that INavigation has to be passed from the UI into the CTOR of the VM. IMHO, This creates a few problems:
1) The VM must be set in the CTOR of the view. That prevents you from doing this.
2) A UI property now has to be passed to the VM.
3) Doing it this way means that you cannot share VMs between WPF and Xamrin Forms projects as WPF doesn't have INavigation.
One this last point... I got the impression from reading up on Xamarin Forms that it's all about sharing code. It seems to me that I could have VMs in a shared project, and use the them in both WPF and Xamarin Forms apps. For example, a LoginViewModel is a good candidate.
Again, I'm very new to Xamarin Forms. I would like to share VMs if I can. I'm open to hearing how this should work.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
Why do you want to mix Xamarin form and WPF if i may ask ?
You can create a Xamarin Standard Project and create the content pages there and other types of pages or views you want to add , after that do your UI there and if there is a limitation on the Xamarin Forms you can use Custom Renders and this UI changes you have made in the standard form will be outputted to different platforms which is ios and Android.
i know you have knowledge of WPF , you can use it on Xamarin Form. but leave WPF out of Mobile dev for now.
Spoted in Daniweb-- Sorry to rant. I hate websites. They are just wierd. They don't behave like normal code.
I am plotting out how to design an app I have in mind, but I wanted to get advice on what the best path to success would be.
End Format -> iOS, Amazon Fire TV
App Purpose -> Music player, organize playlists.
Two methods of playback are play on the server using something like mpg123, or easier method will be playback on device that is accessing files over the network.
The music sits on a Samba share but I would like any kind of NFS style share comparability.
This is partially a programming exercise, as I'm sure plenty of options already exist.
My first thoughts on approach:
C# -> Very Verbose and I only know basics
Delphi / Free Pascal -> Much more readable, though far fewer guides to help.
JS/PHP -> WebApp maybe the easiest to write, I have some PHP experience. Though get the impression my execution would be "hacky". Lots of ducktape.
To be honest, you don't have a lot of choice. iOS and Amazon Fire TV are very different beasts - one it iOS (IPhone, iPad) and the other is Android (as hacked about by Amazon) - so unless you want to write two different apps, your best approach is browser based, or Xamarin - and that means C#.
And do bear in mind that "play on the server" means just that: the client will not be able to see of hear anything unless they are in the same room ... mpg123 is a unix based music player, it won't magically make the sound come out of speakers a thousand miles away.

Thanks OG, that's my concern is cross platform is still no man's land to some degree.
The hacky/easiest way I could think of is hook up speakers to my server (Raspberry Pi clone) and toggle music on and off with mpg123. I would at least like the option for both, play on local device or server.
I read a little about bringing webapps to Amazon Fire. Are there any ways to bring a web app onto iOS? My concern is that a web app would not have capability to reach out to a local (not internet facing) NFS share.
So I want to program an app, where I use the tweepy api. On the frontend of the app, I want to display a list of objects on which can be pressed. If one of them is pressed one new page will open and there I want to display some integer values, which are updating depending on some tweets.
So in the backend I have tweepy where I program with python and the frontend. I started to work with the django framework + react but I do not know if this is the best way to program an app like that. Could you give me some advices on which framework I should use?
On my home page ( [DELETED] )...the Navigation Bar scrolls correctly on any computer display. But on any cell phone, it will not scroll upward and out of the way of the content below it (content which is very important to view fully).
Is there some code snippet that can be added to accommodate this?
Don't post your website here unless you want us to consider you a spammer and throw you off.
I was that close with this one as it was, but you've been here a while so I decided to warn you instead. Others have a twichier trigger finger, so unless you refrain from doing it in future (and I include text-based "non link URL's" like some of your previous posts in this) it is inevitable that you will be kicked off the site at some point. The automated system we have in place now doesn't like them, and that means your posts will go direct to the tender mercies of whoever sees it in moderation first. That won't always be me ...
I've deleted the link from your post this time.
