How to use a multiselector in Windows Phone 8.1

In Windows Phone 8.0, we have "LongListMultiSelector" to make a multiselect list.
However, in Windows Phone 8.1, I cannot find any tool like "LongListMultiSelector" that can select two or more items.
(It seems that ListView can only select a single item.)
So is there any tool like "LongListMultiSelector" that can be used in WP8.1? Thx~

Hi , Just modify ListView style you can create your own design.
Main style of ListView Item is as below
<Style TargetType="ListViewItem" x:Key="ListViewItemExpanded">
<Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
<Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
<Setter Property="Background" Value="Transparent"/>
<Setter Property="TabNavigation" Value="Local"/>
<Setter Property="IsHoldingEnabled" Value="True"/>
<Setter Property="Margin" Value="0,0,18,2"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Top"/>

How to use PrepareStatementAsync statement in windows phone development ?

Hi,
I am new in windows phone 8.1 development.
I want to use select query using PrepareStatementAsync.
Which namespace or directory i have to use.
Please help me.

Hi Ravi,
Based on search result, looks like this method belongs to a SQLite wrapper, you can add its package to your project using Nuget:
https://www.nuget.org/packages/Sqlite-Winrt/
For more information, I would suggest you referring to its official site.

How can i use shoutcast streams on windows phone?

I have an idea to make an application but i don't know how to use shoutcast streams in windows phone ? Is there any API or something that i need to fallow?
Alican

At the moment Shoutcast audio streams are not supported natively in Windows Phone. You will need to write a self implementation of IMediaStreamSource to parse the audiostream and also handle the http connections to the streaming server.
Another solution is to use a third party implementation such as www.jupitersdk.com.
It offers a well documented API, is easy to integrate and use into your project and there is a trial version for testing purposes.
Jupiter Sdk has successfully been used in several RadioStreaming apps which can be found in the Windows Phone Store. By the way, it allows not only to play Shoutcast and Icecast audiostreams in Windows Phone 8.1, but also to retrieve the stream metadata (i.e.
current Title and Artist), among other interesting features.

How to use 4GB RAM on Windows 2000

Hi,
We use a third party application that parses weblogs and generates statistics.
The application gives OutOfMemory exception when the weblogs are hugs.
I am wondering if doing "editbin.exe /LARGEADDRESSAWARE java.exe" is going to help.
I have 4GB of physical RAM and I have /3GB in boot.ini in Windows 2000 Advanced Server.
Thanks,
Anurag.

How to use 4GB RAM on Windows 2000You are never going to use 4g on a windows box. The maximum addressable space is 4g. Normally the OS reserves 2g. Which means the maximum addressable space for an application is 2g.
It is supposed to be possible to increase the addressable space to 3 gig. And also increase the JVM space. However, there are risks. The following thread suggests a way to do this

How to disable webview cache for Windows Phone 8.1 Runtime universal app?

Is it possible to disable cache for the Webview control for a Windows Phone 8.1 runtime universal app? My App seems to be remembering the information it received the first time. My app logs me into a service and when I go back to rerun app in the emulator
(without completing shutting down the emulator) it logs me in automatically rather than giving me the prompt. This behavior is in the NavigationCompleted handler if that helps explain a bit more on where I am hitting this issue.
If I were to shut off the emulator completely and then restart it then I am prompted for the login name and password again. I have gotten over this cache issue, when I was using the HttpClient in other part of my app, by sending the no-cache in the header
as:
client.DefaultRequestHeaders.Add("Cache-Control", "no-cache");
Can I do something similar for the webview control?
thanks
mujno

Hi mujno,
As I know currently there is no programmatically way to clean cache for WebView, see Matt's blog:How to clear the WebView cache
However if you are developing an enterprise app, you should be able to invoke some scripts to clean for you, see this for more information:Brokered

How to develop a Library for Windows Phone 8.1?

Hello guys!
I'm a quite new developer in this topic, I have never created a Library and right now, I need to create a library using this project of C because the normal OCRs cannot recognize 7 segments display:
https://www.unix-ag.uni-kl.de/~auerswal/ssocr/
Last year, I used a library for SQLite (in the beginning it didn't have a Nuget package) and you must add a C++ project to execute SQLite code in WP8. I hope someone might give me an idea where to read and help me with this project. Thanks a lot
for your worthy knowledge.
Federico Navarrete

I need to use a special OCR that detects 7 Segments Displays. I have been reading during the week and I discovered that the most similar project is this one:
Seven Segment Optical Character Recognition
However it's a C project not a C# or VB and I must create a special library (or project) to integrate with my Windows Phone App. As I said before last year I used this article:
How to use SQLite in Windows Phone
And in the beginning it was just a C++ project that you must add to manipulate SQLite. So, I think I should create something like that for migrate those libraries and later integrate with my project but I have never worked with this kind of libraries
or create C/C++ libraries that finally will work with a C# App. Thanks for your time.

How to import MySql database to windows phone 8.1 app

Hello everyone I'm Designing a new windows phone 8.1 app and I need some help from you.
I have a database that Im using for the some app but for Windows.
currently using db4free.net
and use this code
Mysqlconn = New MySqlConnection
Mysqlconn.ConnectionString = "server=db4free.net;Port=3306; user id=%%%%%; password=%%%%%%%; database=%%%%%%%%"
Dim READER As MySqlDataReader
Try
Mysqlconn.Open()
Dim Query As String
Query = "SELECT * FROM Manager WHERE Name='" & TextBox1.Text & "' AND Password='" & TextBox2.Text & " ' "
Command = New MySqlCommand(Query, Mysqlconn)
READER = Command.ExecuteReader
Dim count As Integer
count = 0
While READER.Read
count = count + 1
End While
If count = 1 Then
MsgBox("Mire se vini'" & TextBox1.Text & "'")
FORMAKRYESORE.Show()
Me.Close()
ElseIf count > 1 Then
MsgBox("Mire se vini'" & TextBox1.Text & "'")
Else
MsgBox("Manager'" & TextBox1.Text & "' is not in the data")
End If
Mysqlconn.Close()
Catch ex As MySqlException
MsgBox(ex.Message)
Finally
Mysqlconn.Dispose()
End Try
this is the code that I use to login. but on windows phone cant import Mysql connector. not sure why... any suggestion how to deal with this?
or should I use SQLite? I dont know nothing about the code on SQLite...

If this is supposed to work just on the phone then SQLite or a Local database.
https://msdn.microsoft.com/en-us/library/windows/apps/hh202860(v=vs.105).aspx
For small amounts of data, serializing and deserializing classes to isolated storage is faster.
Phones aren't always connected to the interweb.
Even if you are planning on using a central database on some server and connecting via services, you will almost always also need to store some data locally.
It's in your interest to ask questions in the appropriate forum for the technology you're using.
As it is, you're asking wpf developers a question about windows store app development.
It's similar but different.
Which is probably why Magnus is unaware of local database and I probably omitted something else.
It's not what we do.
I've written a grand total of one windows store apps.
Magnus probably has a similar level of experience.
Hope that helps.

How to play live streaming in windows phone 8.1 silverlight app?

Hi,
I am developing a windows phone 8.1 silverlight app. In my I want to show live streaming youtube channel , I think it is not possible,
Actually that youtube channel is a television channel , I want to stream that live tv in my app.(I tried to load youtube channel in webbrowser in iframe tag but it is not opening)
Anybody help me how to play live tv or live streaming in my app,
Thanks..
Suresh.M

Hello,
You will likely need to write a custom
MediaStreamSource that can access the media stream and parse it. Windows Phone supports h.264 natively and as long as the site serves up a media stream that contains h.264 frames you can parse it and have our built in decoder decode and display it. You
will need to have intimate knowledge of the streaming protocol used by the website that you are trying to play. You must also make sure that the website is not using protected content. IANAL so I would recommend that you have your local law professional
(lawyer) review the licensing of the website that you are attempting to connect to and stream from before continuing your development. Your lawyer can make sure make sure their licensing allows you to do this.

How to dismiss messageDialog programaticaly in Windows Phone 8.1..?

How can I dismiss a Message dialog programmatically in Windows Phone 8.1. I created the dialog using showAsync(). If this is not possible which is the best method to create a custom message dialog
with the following properties:
1. It can show test and hold buttons for user interaction.
2. It can be dismissed programmatically
3. Should block the view as a Normal MessageDialog do

How to make backward compatibility of windows phone 8.1 app for windows phone 7?

I developed windows phone 8.1 app which is in windows phone store. Now, i want to make this app compatible for windows 7 also. Is it possible, if yes then how?

It may be that you are using non-backward compatible capabilities in your Windows Phone 8.1 app(s).
Developers that want to develop for different OS's usually have platforms with the different OS's on them for developing applications so they work on each platform.
I suppose you developed for Windows phone 8.1 rather than Windows phone 7. Therefore your app runs on a different framework than a Windows phone 7 has as well as probably newer hardware with greater capabilities.
So you will probably need to purchase an older phone that came with Windows phone 7 in order to develop for. I couldn't find documentation like the last link below (App capabilities and hardware requirements for Windows Phone 8) for Windows phone 7
from Microsoft but maybe you can.
Windows Phone OS 7.1 - Developing a Windows Phone Application from Start to Finish
Types of Applications
The Windows Phone application platform provides two frameworks for developing applications:
Silverlight
The Silverlight framework supports event-driven, XAML-based application development.
XNA
The XNA Framework supports loop-based games.
Silverlight and XNA can also be combined in a single application.
The following table lists some of the criteria that you can use to determine whether you should use Silverlight or the XNA Framework for your Windows Phone application. With Windows Phone OS 7.1, you can combine Silverlight and XNA into one application.
For more information about Silverlight and XNA, see
The Silverlight and XNA Frameworks for Windows Phone. For more information about the application platform, see
Application Platform Overview for Windows Phone.
What's New in Windows Phone 8.1
Platform convergence with Windows Store apps
Windows Phone 8.1 introduces an important change in the Windows Phone developer ecosystem. In this release, Windows Phone converges with the Windows Store apps platform into a single developer platform that runs the same types of apps—Windows Runtime apps.
Platform convergence began in Windows Phone 8, which supports a small subset of Windows Runtime APIs, but which differs from Windows in many core areas. In Windows Phone 8.1, there’s so much more in common—a much larger API set, a similar app model
and life cycle, a shared toolset, a common UI framework—Windows Phone and Windows Store app developer platforms truly have become one, single development platform.
Of course there are still some small differences in behavior and supported features between Windows Phone and Windows Store apps. Some of these are the result of timing of the different product cycles, and they may not appear in future releases. Some differences
are the result of the different natures of phones and computers, their sizes, and the way people use them. We encourage developers to think in terms of Windows app development—developing for a single Windows Runtime, but targeting two different platforms on
phones and computers.

Is there a way to use Itunes with a windows phone?

I just bought a windows phone and would like to bring in tracks from my Itunes library to use as ringtones. I have 5000+ tracks in my Itunes (for windows) library and refuse to purchase any more as ringtones.
Is there a Itunes for windows phone app I can get? Or is there a good 3rd party software utility that I can use to import tracks to my phone, either using the web; or with a direct connection. My phone has the Zune software and it will not allow tracks within it used as ringtones.

No.
