is there a way to check the app is installed for first time.I want this info cause i want to provide a small introduction session about the app features when user run the app for the first time.I want this to develop in windows phone 8.1 in c#
any help is welcome
Thank you
Maybe somethink like this:
On ApplicationStart:
Windows Phone 8:
if (!IsolatedStorageSettings.ApplicationSettings.Contains("FirstStart"))
{
//ShowTutorial
}else
{
IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
if (!settings.Contains("FirstStart"))
{
settings.Add("FirstStart", "false");
}
//Start normal.
}
Here is a quickstart about Application Settings on Windows Phone: https://msdn.microsoft.com/en-us/library/windows/apps/jj714090%28v=vs.105%29.aspx
Windows Phone 8.1
On ApplicationStart:
var localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
if (localSettings.Values["FirstStart"] == null)
{
//ShowTutorial
}
else
{
localSettings.Values["FirstStart"] = "true";
}

I have an UWP app (published in Windows/Microsoft Store), and I am working in a new update, and I use Template10 in my app, that has dark and light theme, and in Windows 10 Mobile but for the change to be effective, the user has to manually close the app and restart it.
Is there any possibility to restart/reboot my application? That is, to close the application alone/automatically and reopen my application automatically?
With the Fall Creators Update (1709) We have introduced a new method on CoreApplication called RequestRestart() that enables this scenario. You will need the 16299 SDK (or later) to access this API.
https://learn.microsoft.com/en-us/uwp/api/windows.applicationmodel.core.coreapplication#Methods_
Here is a blog/sample:
https://blogs.windows.com/buildingapps/2017/07/28/restart-app-programmatically/
You can do this with CoreApplication.RequestRestart
var result = await CoreApplication.RequestRestartAsync("Application Restart Programmatically ");
if (result == AppRestartFailureReason.NotInForeground ||
result == AppRestartFailureReason.RestartPending ||
result == AppRestartFailureReason.Other)
{
var msgBox = new MessageDialog("Restart Failed", result.ToString());
await msgBox.ShowAsync();
}
This question already has an answer here:
Recognize when is the app first launched WP8
(1 answer)
Closed 8 years ago.
I'm quite new on windows phone dev. I would like to detect when the user launches my app for the first time to display an explaination frame for example by calling :
if(firstLaunch)
showTheFrameToTheGuyBecauseHeLaunchedTheAppForTheFirstTime();
I would be sooooooo glad if someone could show us such a small script...
Thank you in advance guys !
I would recommend you to use the builtin applicationsettings.
const string settingsAppLaunched = "appLaunched";
public static bool IsFirstLaunch(){
IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
return !(settings.Contains(settingsAppLaunched) && settings[settingsAppLaunched]);
}
public static bool Launched(){
if(IsFirstLaunch()){
IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
settings.Add(settingsAppLaunched, true);
settings.Save();
}
}
//usage:
if(IsFirstLaunch()){
showTheFrameToTheGuyBecauseHeLaunchedTheAppForTheFirstTime();
Launched();
}
Microsoft Documentation about Settings in Windows Phone is available here.
You can simply use IsolatedStorageSettings.
if(!IsolatedStorageSettings.ApplicationSettings.Contains("first"))
{
// Do your stuff
IsolatedStorageSettings.ApplicationSettings["first"] = true;
IsolatedStorageSettings.ApplicationSettings.Save();
}
This code will do it.
The question in title is not the real problem. I went through many sites and blogs and go to know that Environment.OSVersion gives you the current OS version of the phone using our app. But the problem is, There is no OSVersion under the class Environment. Please refer the screenshot for better understanding.
My question why I am not able to see the OSVersion property under Environment class? Am I missing something?
Universal/WinRT apps only work in wp 8.1, so the OS version can only be 8.1. When they make wp8.2 or wp9, they'll probably add a way to check what OS version is installed...
If you're looking for the firmware version, you can get it with:
Windows.Security.ExchangeActiveSyncProvisioning.EasClientDeviceInformation deviceInfo = new Windows.Security.ExchangeActiveSyncProvisioning.EasClientDeviceInformation();
var firmwareVersion = deviceInfo.SystemFirmwareVersion;
Copied from duped question:
Windows Phone 8.1 Silverlight apps can use the .NET version APIs. There is no supported mechanism to get a version number in Universal 8.1 apps, but you can try using reflection to get the Windows 10 AnalyticsInfo class, which will at least tell you the version number if you are running on Windows 10.
Note: Checking the OS version is almost always the wrong thing to do, unless you're simply displaying it to the user (eg, in an "About" box) or sending it to your back-end analytics server for number crunching. It should not be used to make any run-time decisions, because in general it's a poor proxy for whatever-you're-actually-trying-to-do.
Here is a sample:
var analyticsInfoType = Type.GetType(
"Windows.System.Profile.AnalyticsInfo, Windows, ContentType=WindowsRuntime");
var versionInfoType = Type.GetType(
"Windows.System.Profile.AnalyticsVersionInfo, Windows, ContentType=WindowsRuntime");
if (analyticsInfoType == null || versionInfoType == null)
{
Debug.WriteLine("Apparently you are not on Windows 10");
return;
}
var versionInfoProperty = analyticsInfoType.GetRuntimeProperty("VersionInfo");
object versionInfo = versionInfoProperty.GetValue(null);
var versionProperty = versionInfoType.GetRuntimeProperty("DeviceFamilyVersion");
object familyVersion = versionProperty.GetValue(versionInfo);
long versionBytes;
if (!long.TryParse(familyVersion.ToString(), out versionBytes))
{
Debug.WriteLine("Can't parse version number");
return;
}
Version uapVersion = new Version((ushort)(versionBytes >> 48),
(ushort)(versionBytes >> 32),
(ushort)(versionBytes >> 16),
(ushort)(versionBytes));
Debug.WriteLine("UAP Version is " + uapVersion);
Obviously you can update this to return the version etc. rather than print it to the debug console.
You cannot get the OS Version in Windows 8.1 .Check the following link for the same - https://social.msdn.microsoft.com/Forums/windowsapps/en-US/2b455331-3bad-4d26-b615-a59d0e05d0dd/how-to-get-os-version-on-window-phone?forum=wpdevelop
I found a tricky way to detect if a device is running a Windows Phone 8.1 or Windows Phone 10. I compared 3 different devices, a Nokia Lumia 925 ( wp 8.1 ) a Nokia Lumia 735 ( wp 10 ) and a Nokia Lumia 930 ( wp 10 ). I noticed that on wp8.1 there is no device info id ( it causes a not implemented exception ) but it exists on windows phone 10 on both tested devices. Morover the system firmware version format seems different between wp 8.1 and wp 10 ( the first is xxxx.xxxxx.xxxx.xxxx while the second is xxxxx.xxxxx.xxxxx.xxxxx ). Below my function:
/// <summary>
/// Indicates if this device is running a version of Windows Phone 8.1. It use a dirty trick for detecting the OS major version
/// based on the system firmware version format (8.1 is xxxx.xxxxx.xxxx.xxxx while 10 is xxxxx.xxxxx.xxxxx.xxxxx )
/// moreover, the "deviceInfo.id" is not implemented on Windows Phone 8.1, but it is on Windows Phone 10
/// </summary>
/// <returns></returns>
public static bool liIsWindowsPhone81(bool basedOnDeviceInfoId)
{
EasClientDeviceInformation deviceInfo = new Windows.Security.ExchangeActiveSyncProvisioning.EasClientDeviceInformation();
bool isWin81 = false;
if (basedOnDeviceInfoId)
{
try
{
var deviceInfoId = deviceInfo.Id;
}
catch
{
isWin81 = true;
}
}
else
{
string firmwareVersion = deviceInfo.SystemFirmwareVersion.Trim();
string[] parts = firmwareVersion.Split('.');
if (parts[0].Length == 4 && parts[1].Length == 5 && parts[2].Length == 4 && parts[3].Length == 4)
{
isWin81 = true;
}
}
return isWin81;
}
I haven't had the opportunity to test this on further devices, but so far seems to work. I use it to distinguish the code for the app rating function between Windows Phone 8.1 and Windows Phone 10, that in my specific case are not UWP
Hope this helps
If your app is Silverlight based, you can use System.Environment.OSVersion.Version across Windows Phone 8.0 and 8.1 as well as Windows Mobile 10.
Here is an example of a method we utilize when determining whether to display our own opt-in dialog for geo-tracking or let the Windows Mobile 10 present its own opt-in dialog.
public static bool IsWindowsPhone8x()
{
try
{
Version version = System.Environment.OSVersion.Version;
return version.Major > 8 ? false : true;
}
catch (Exception)
{
return false;
}
}
Simply use this line to get the Application Name and Id, publisher name etc...
string name = Windows.ApplicationModel.Package.Current.DisplayName;
I have an application that requires to control mobile broadband API.
I am struggling on correctly installing the api on my devices.
I've been follow the instructions in this document:
http://www.google.be/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=1&cad=rja&ved=0CC0QFjAA&url=http%3A%2F%2Fdownload.microsoft.com%2Fdownload%2F7%2FE%2F7%2F7E7662CF-CBEA-470B-A97E-CE7CE0D98DC2%2FMB_ManagedCode.docx&ei=kyvmUs7jE4e60QWbooHYDg&usg=AFQjCNG6yaGf4sRhdbWI99fE7tmQX8cmnA&sig2=2Fg-_DRYBIselKR19wTq2Q
and trying to combine the steps with this stackoverflow explanation
C# Read Windows Mobile Broadband connection properties
I have been able to lay a reference from visual studio to mbnapi.tlb in V7.0/lib. and I automatically now have a interop.mbnapi.tlb in my obj/debug folder.
When trying to "check the SIM is inserted and working / activated". => my code crashes on the following line
IMbnInterface[] mobileInterfaces = mbnInfMgrInterface.GetInterfaces() as IMbnInterface[];
When I run it on windows 8, mbnInfMgrInterface == null
I have already tried to install the same SDK on windows 8 as stated in the requirements of the document but the SDK is only meant for windows 7...
I have tried to register the mbnapi in windows 8 by performing
Regtlibv12 Mbnapi.tlb
no luck whatsoever...
what do I need to do to get this to work please?
anyone has some experience in this?
EDIT. on windows 7 (my development machine), I get the message "Device not ready", I think this is normal because I don't have mobile broadband on it, on windows 8 I do, but there the mobile interface manager is null => mbnInfMgrInterface == null.
thank you,
Not sure exactly what you are after, but after struggling with IMbnInterface and GetSignalStrength() (see https://msdn.microsoft.com/en-us/library/windows/desktop/dd323166(v=vs.85).aspx) and being unsuccessful, I found that you can obtain a lot of info using WMI:
int maxBandwidth = 0;
string query = "SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface";
ManagementObjectSearcher moSearch = new ManagementObjectSearcher(query);
ManagementObjectCollection moCollection = moSearch.Get();
foreach (ManagementObject mo in moCollection)
{
if (Convert.ToInt32(mo["CurrentBandwidth"]) > maxBandwidth)
{
// Instead of CurrentBandwidth you may want to use BytesReceivedPerSec
maxBandwidth = Convert.ToInt32(mo["CurrentBandwidth"]);
}
}
Please see answer here: Determining the network connection link speed and here is the list of properties you can obtain: https://msdn.microsoft.com/en-us/library/aa394293(VS.85).aspx
UPDATE:
Please note that I can build and debug the above code (as part of a larger WPF application) from within Visual Studio 2015 on either Windows 7 or Windows 8.1, and I can deploy the same application onto Windows 7 where it runs successfully. For some reason when I deploy this application on Windows 8.1, I get an Invalid query message.
UPDATE 2:
Please note that I found you cannot get the network info in Windows 8.1 in the same way as you do in Windows 7, in that the System.Management namespace is not available on Windows 8.1. See https://code.msdn.microsoft.com/windowsapps/network-information-sample-63aaa201
string connectionProfileInfo = string.Empty;
ConnectionProfile InternetConnectionProfile = NetworkInformation.GetInternetConnectionProfile();
if (InternetConnectionProfile == null)
{
rootPage.NotifyUser("Not connected to Internet\n", NotifyType.StatusMessage);
}
else
{
connectionProfileInfo = GetConnectionProfile(InternetConnectionProfile);
OutputText.Text = connectionProfileInfo;
rootPage.NotifyUser("Success", NotifyType.StatusMessage);
}
// Which calls this function, that allows you to determine how strong the signal is and the associated bandwidth
string GetConnectionProfile(ConnectionProfile connectionProfile)
{
// ...
if (connectionProfile.GetSignalBars().HasValue)
{
connectionProfileInfo += "====================\n";
connectionProfileInfo += "Signal Bars: " + connectionProfile.GetSignalBars() + "\n";
}
// ...
}
I'm trying to set up local settings so I can store data in my Windows Mobile 8 app. The first step I'm trying is:
ApplicationDataContainer localSettings = ApplicationData.Current.LocalSettings;
Just having that in my code causes the app to fail when debugging on my device.
Any ideas why?
I have "using Windows.Storage;" set. The actual code doesn't throw up any errors.
I needed to use the IsolatedStorageSettings feature, as below:
IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;
if (!settings.Contains("test"))
{
settings.Add("test", urlText.Text);
}
else
{
settings["test"] = urlText.Text;
}
settings.Save();
