Why is this not working. i am pasting normal string...
private void button5_Click(object sender, RoutedEventArgs e)
{
TextBox02.Text = Clipboard.GetText();
}
Clipboard.GetText is not available to Windows Phone applications. MSDN states:
You cannot get clipboard text from a Windows Phone application, only set it. Calling the GetText method in a Windows Phone application will always cause a SecurityException to occur.
Reference
I am not aware of any way to read the clipboard data in Windows Phone.

I am working on a barcode reader app for Android and Windows. On Android, I receive a system broadcast for every barcode scanned, but on Windows the typical configuration is a keyboard entry sent from the barcode scanner. So what I am trying to do is capture the KeyDown/KeyPress event so that I can add all characters received into a temporary string and then submit to my app as a "barcode read event" as soon as "Enter" is received.
However, I am unable to find KeyDown/KeyPressed events in any of the controls. Is that possible at all? If so, where do I look? The closest (I think) I have gotten is this description of how to use the App lifecycle events: https://learn.microsoft.com/en-us/dotnet/maui/fundamentals/app-lifecycle
Thanks and best regards,
Joerg.
If you are using an Entry you don't need to read all keys, instead you can subscribe to Completed event witch is fired when Enter is readed into the Entry.
So many barcode readers can be configured to insert Enter as last part of barcode readed.
MyBarcodeReader()
{
MyBarCodeEntry.Completed += MyBarCodeEntry_Completed;
}
private void MyBarCodeEntry_Completed(object sender, EventArgs e)
{
/// Do your JOB
}
For windows it is better to hook into the native keyboard system, which makes sure you always receive input.
When using an Entry you're never sure that an entry has focus and is capable of receiving input.
A great tool for this is SharpHook.
I am trying to implement Screen broadcast with Unity using the Agora Video Chat SDK for Unity. I used this source, which doesn't work initially. But after modifying the code as below, I am able to receive my own stream through the server, inside Unity editor (2019.1.2f1).
//Adding inside Start
mRtcEngine.OnJoinChannelSuccess = Joined;
}
private void Joined(string channelName, uint uid, int elapsed)
{
var videoSource = FindObjectOfType<VideoSurface>();
videoSource.SetForUser(uid);
videoSource.SetEnable(true);
}
But nothing happens in the Windows build. I checked the VideoSurface.cs file. I am continuously getting tmpi = -1 inside Update. What could be the reason?
PS. I check all firewall permissions for the build. Also, the user is able to join the channel. It's just the stream that is not being received. Help appreciated.
You shouldn't need to modify the code like that. And also, in the code above you register the callback for the local user. If you want to show remote user's video, you should register the callback for OnUserJoined().
Have you seen the tutorial about the Screensharing? https://www.agora.io/en/blog/how-to-broadcast-your-screen-with-unity3d-and-agora/
Please try that. If you are still confused, you may take a look at this github repo. It has different contents to share, but the concept and Agora API usage are pretty much the same.
I am working on an app in which I have to restrict the user to share the apk personally. One can download it but should not be allowed to share the App (apk) personally via bluetooth etc.
I searched and read alot about the same issue but didn't find a complete answer. I have tried the below.
How to get the file *.apk location in Android device
Download, Installing and Delete .apk file on android device programmatically from a website other than marketplace
What I have understood from above is that the easy way to do this is to delete the apk file from the User's device after the app is installed. (I also know that user may generate this apk again via root access but that is fine as at-least I will be able to restrict not all but many).
Now what I have tried, I am registering a Broadcast receiver and in my onReceive() method I have the below,
PackageManager pm = getPackageManager();
for (ApplicationInfo app : pm.getInstalledApplications(0)) {
if (myPackage.equalsIgnoreCase(app.packageName)) {
apkPath = app.sourceDir;
break;
}
}
Log.d("Package", myPackage + " - APK - " + apkPath);
if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {
File sdcard = Environment.getExternalStorageDirectory();
File file = new File(sdcard, apkPath);
file.delete();
}
But this does nothing as I am not aware of the IntentFilter I should use to register this.
Can any one guide me on what is the next step? and in case I am completely on a wrong land then help me achieve the above?
Any help will be appreciated. :)
On later versions of Android, some (all?) broadcasts aren't sent to an app until it has been manually opened at least once. This is a security feature that can't be circumvented.
As far as I know, It is not possible to listen the installation complete broadcast event. Android Api having Broadcast Action: "ACTION_PACKAGE_ADDED" But newly installed package does not receive this broadcast. Source : Here
My suggestion is check in your first launcher activity and delete the apk.
You can use the Android App Licensing Service here.
Refer http://developer.android.com/google/play/licensing/index.html and the implmentation here http://developer.android.com/google/play/licensing/adding-licensing.html.
This will ensure that the apk cannot be shared(making it protected) using any of the apps available on market.
Sorry for bad english.
Here my solution not actual code:
1) set your broadcastreciver when any new application is install in your device.
2) When your broadcastreciver is call, that time you write code in onRecive() method
check the your app package if install or not
private boolean isPackageInstalled(String packagename, Context context) {
PackageManager pm = context.getPackageManager();
try {
pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
return true;
} catch (NameNotFoundException e) {
return false;
}
}
using this method or any
if you get true means your application is install
3) if you get true from isPackageInstalled("com.download.app", context) method
that time delete apk file from your SD card or any loaction in device
if you more clarification i will be explain.
i used the idea of creating a folder when the app runs for the first time .if it doesnot exist , delete the apk. if the folder exists , then the apk has already been deleted.
This folder will be deleted on its own if the app is unstalled.
public static String link = Environment.getExternalStorageDirectory()
.getPath() + "/Android/data/YourAppPackageName/";
//check if its running for the first time
File f = new File(link);
if (f.exists()) {
File f1 = new File("/data/app/YourAppPackageName.apk")
if(f1.exists()){f1.delete();}
}
else {
f.mkdirs();
}
You can also use the HockeyApp product and distribute using the Android App that they provide, as well as enable the "restriction" features. I'm pretty sure that will do what you need without having to write extra code.
I would like to open a URL in private mode from a Thunderbird extension. Right now, the following code works in "standard" non-private mode:
try {
var eps = Components.classes["#mozilla.org/uriloader/external-protocol-service;1"].
getService(Components.interfaces.nsIExternalProtocolService);
var ios = Components.classes["#mozilla.org/network/io-service;1"].
getService(Components.interfaces.nsIIOService);
eps.loadURI(ios.newURI("http://www.example.com", null, null));
} catch (err) {}
Any idea how to achieve the same result in private mode? I'm interested to make it work with launching Chrome as the default browser. (Once again, Chrome is correctly launched with the code above).
You cannot really launch Firefox with a new url in a private window AFAIK. -private-window <url> will open a new private window, but still put the new tab in a regular one.
Chrome can be launched with chrome --incognito <url>, however you would need to launch it yourself via nsIProcess and therefore would first have to figure out where the chrome binary is.
If you can guarantee that the default handler is Chrome, then you might use nsIExternalProtocolService.getProtocolHandlerInfo(), use preferredApplicationHandler and QueryInterface that to nsILocalHandlerApp to find the .executable. Otherwise, you'll have to deal with the OS and/or known paths yourself.
this record plugin stops to work for us with current version of chrome under macOS
Chrome: Version 23.0.1271.97
MacOS: 10.8.2
http://connect.soundcloud.com/examples/recording.html
how to reproduce:
click record
allow using your microphone
-> recording don't start
(In fact sometimes it works (20% of cases for me))
and also sometimes there is an error in console
PepperFlashPlayer.plugin: 0x2A052 is not valid resource ID.
Please help us, we use it for production and a lot of users can not record sound
regards, Dmitry
My investigation show:
sometimes the "SampleDataEvent.SAMPLE_DATA" event not triggered (or not assigned) in flash.
To solve this issue I do:
Added to event handler "StatusEvent.STATUS" (or call manually if microphone unmuted):
tti = setInterval(applySampleData, 100);
Added function:
protected function applySampleData() : void {
microphone.removeEventListener(SampleDataEvent.SAMPLE_DATA, recordSampleDataHandler);
microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, recordSampleDataHandler);
}
And in function "recordSampleDataHandler" (it's SampleDataEvent.SAMPLE_DATA listener):
if(tti) { clearInterval(tti); tti = 0; }
Try this.
