6,006,617 | 0 | <p><em>Edit: user1182474's comment is correct; Wine doesn't isolate the programs it runs. (It tries to hide it, but not very thoroughly.) I totally failed at using Google. Psen's comment below is more correct, and references the FAQ. (Note that, for that to work, you may need to have the program's directory available through a Wine drive mapping. Or, see Anonymous Replier's answer.)</em></p> <p>== Old Answer ==</p> <p>Wine isolates the programs it runs. The applications are, if all works as intended, presented with an environment indistinguishable from Windows. Unfortunately for your purposes, that means that you can't access the features of the host OS (Linux). I mean, you could patch Wine to do that, but I get the impression that it would be more work than it's worth.</p> <p>There is hope! Cygwin is a Unix-like environment for Windows. You could install Cygwin in Wine, and use Cygwin to run your shell script. (Apparently, installing with 'winetricks cygwin' is easiest) Invoke Cygwin's bash shell (inside some Wine program) like this:</p> <pre><code>c:\cygwin\bin\bash myscript </code></pre> <p>Of course, change c:\cygwin to wherever you install it.</p> |

38,064,565 | 0 | App crashes on sendText method <p>I am developing my first android app where someone can send multiple sms to a designated number. The app used to run fine when I had the number and number of messages to be sent already programmed into the code. However, I created a separate activity where one can input the destination number and number of messages to be sent, and transfer that data back to the first activity through an intent. But now the app crashes upon attempting to send a message.</p> <p>Here is the first activity: </p> <pre><code>public class TextMessages extends AppCompatActivity { public static final String DEFAULT = "No Number Found"; private EditText customMessage; String gotNum; FloatingActionButton button; int request_code; String realnum; int temp; int recode; Button butt; int number; String num; String text; int x; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_text_messages); request_code = 1; FloatingActionButton button = (FloatingActionButton) findViewById(R.id.but); assert button != null; button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(TextMessages.this,Settings.class); startActivityForResult(intent, request_code); Intent a = new Intent(TextMessages.this,Settings.class); startActivityForResult(a, recode); } }); customMessage = (EditText)findViewById(R.id.customMessage); } public void onActivityResult(int requestCode, int resultCode, Intent data){ if (requestCode== request_code){ if (resultCode== Activity.RESULT_OK){ num = data.getStringExtra("value"); text = data.getStringExtra("cost"); } } } public void sendText(View view) { String message = ""; if (view.getId() == R.id.fab) { message = customMessage.getText().toString(); } else { Button sender = (Button)view; message = sender.getText().toString(); } //Toast.makeText(this, "Test", Toast.LENGTH_SHORT).show(); int i; x = Integer.parseInt(text); for (i = 0; i < x; i++){ SmsManager smsManager = SmsManager.getDefault(); smsManager.sendTextMessage(num, null, message, null, null); } }} </code></pre> <p>As you can see I have replaced the predetermined number with String num and the number of messages to be sent with int x, which causes the app to crash when the button to send the messages is pressed.</p> <p>Here is the activity where the number and messages to be sent is collected from:</p> <pre><code>public class Settings extends AppCompatActivity { public EditText phoneNum; public Button apply; public EditText msgCounter; public Button save; int msgCount; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_settings); phoneNum = (EditText)findViewById(R.id.phoneNum); msgCounter = (EditText)findViewById(R.id.msgCount); apply = (Button)findViewById(R.id.butto); save = (Button)findViewById(R.id.butt); save.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent pass = new Intent(); pass.putExtra("value", phoneNum.getText().toString()); pass.putExtra("cost",msgCounter.getText().toString()); setResult(Activity.RESULT_OK,pass); finish(); } }); } public void OnButtonClickedApply(View view) { String num; num = phoneNum.getText().toString(); //Toast.makeText(this, num, Toast.LENGTH_SHORT).show(); } public void saveMsg(View view) { msgCount = Integer.parseInt(msgCounter.getText().toString()); } } </code></pre> <p>Also I may add, when inputting data into the second activity. Upon pressing the button to save the data, the activity resets(reloads?) and I have to put the data in a second time, when pressing the button will then take me back to the first activity like it should.</p> <p>Crash Log: </p> <pre><code>06-27 19:14:55.583 2404-2404/com.linfirmware.emergencytext E/AndroidRuntime: FATAL EXCEPTION: main Process: com.linfirmware.emergencytext, PID: 2404 java.lang.IllegalStateException: Could not execute method for android:onClick at android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:293) at android.view.View.performClick(View.java:5198) at android.view.View$PerformClick.run(View.java:21147) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) Caused by: java.lang.reflect.InvocationTargetException at java.lang.reflect.Method.invoke(Native Method) at android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:288) at android.view.View.performClick(View.java:5198) at android.view.View$PerformClick.run(View.java:21147) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) Caused by: java.lang.SecurityException: Sending SMS message: uid 10057 does not have android.permission.SEND_SMS. at android.os.Parcel.readException(Parcel.java:1599) at android.os.Parcel.readException(Parcel.java:1552) at com.android.internal.telephony.ISms$Stub$Proxy.sendTextForSubscriber(ISms.java:768) at android.telephony.SmsManager.sendTextMessageInternal(SmsManager.java:310) at android.telephony.SmsManager.sendTextMessage(SmsManager.java:293) at com.example.rahul.customtext.TextMessages.sendText(TextMessages.java:94) at java.lang.reflect.Method.invoke(Native Method) at android.support.v7.app.AppCompatViewInflater$DeclaredOnClickListener.onClick(AppCompatViewInflater.java:288) at android.view.View.performClick(View.java:5198) at android.view.View$PerformClick.run(View.java:21147) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616) 06-27 19:14:57.765 2404-2404/com.linfirmware.emergencytext I/Process: Sending signal.

One more workaround:</p> <pre><code>foreach (string name in a.Keys){ StackPanel SP = new StackPanel(); TextBox TB1 = new TextBox(); TextBox TB2 = new TextBox(); SP.Children.Add(TB1); SP.Children.Add(TB2); // ... Content to TextBoxes TB2.Name = name; MainCheckBox.Clicked += (sender, e) => { TB2.Height = MainCheckBox.IsChecked ? 300 : 0; } } </code></pre> <p>But let's see what should be the correct way.</p> <p>First of all, you need the data items to be presented in a bindable form. This means either derive from <code>DependencyObject</code> or implement <code>INotifyPropertyChanged</code>. Second, you need to put your objects into an <code>ObservableCollection</code>. Then, you can use different containers like <code>ListView</code> or <code>ListBox</code> for displaying the collection of data. For the type representing the data item, you'd need to create a <code>DataTemplate</code>, in which you can put any custom logic you need.</p> <p>You see that this is quite a lot of work, so I wouldn't recommend this approach for really small applications; however as your application grows, this approach will show its benefits.</p> |
20,888,726 | 0 | <p>Well, if your old one is working then the problem will be in your rewrite. Don't pay too much notice to the error messages, they're pretty much par for the course, and can be triggered by something as benign as a cache miss. Unless you're actually getting an error callback somewhere, the log messages are meaningless.</p> <p>As for your problem, I can't really make any guesses without seeing your code. One thing to check and is the most common course of a permanent error is to make sure you're actually logged in. The login process is asynchronous, and any functionality that requires you to be logged in (searching is one of them) will fail before login is completed.</p> |

41,051,163 | 0 | <p>Your best bet will be to learn Objective-C. It's not difficult to pick up, especially if you already have a strong understanding of C.

Carbon was never updated to support 64-bit applications, and lacks many features that have been added to Cocoa since the 64-bit transition (~2005). It's also very awkward to write an application in, as it was designed in large part to ease porting of applications written for Classic Mac OS.</p></li> <li><p>There's also X11, with an appropriate UI library like GTK. <strong>I wouldn't recommend this either</strong>. Neither X11 nor any UI libraries for it are installed by default -- they must be installed by the user -- and applications which use X11 have a significantly different interface from native applications.</p></li> <li><p>A third-party UI library. Most of the ones I can think of offhand (QT, wxWidgets, and FLTK) require C++, though. <a href="https://www.gtk.org/download/macos.php" rel="nofollow noreferrer">GTK+</a> does have a C interface and natively supports a macOS interface, but it's not particularly native.</p></li> <li><p>A library specific to your use case.

My comments are on a separate hidden channel. Here are the grammar rules for the hidden tokens:</p> <pre><code>/* Comments and whitespace -- Nested comments are allowed, each is redirected to a specific channel */ COMMENT_1 : '(*' (COMMENT_1|COMMENT_2|.)*?

So, when you send your parameters into your D class, it is sending your code to your M class, it is executing it which gives you "DVD" on your screen and then it is changing the value of n. After that you are sending the "Unknown" value your M class directly which is not related with your D class anymore and it is showing you "Unknown" on your screen. At the end you are requesting D class' n value which is already "DVD". So the result is DVD Unknown DVD:DVD. I hope this makes sense for you.</p> |

6,341,566 | 0 | <p>The terminology is a bit confusing indeed, but both <code>javax.net.ssl.keyStore</code> and <code>javax.net.ssl.trustStore</code> are used to specify which keystores to use, for two different purposes. Keystores come in various formats and are not even necessarily files (see <a href="http://stackoverflow.com/questions/6157550/question-on-java-keystores/6157716#6157716">this question</a>), and <code>keytool</code> is just a tool to perform various operations on them (import/export/list/...).</p> <p>The <code>javax.net.ssl.keyStore</code> and <code>javax.net.ssl.trustStore</code> parameters are the default parameters used to build <code>KeyManager</code>s and <code>TrustManager</code>s (respectively), then used to build an <code>SSLContext</code> which essentially contains the SSL/TLS settings to use when making an SSL/TLS connection via an <code>SSLSocketFactory</code> or an <code>SSLEngine</code>. These system properties are just where the default values come from, which is then used by <code>SSLContext.getDefault()</code>, itself used by <code>SSLSocketFactory.getDefault()</code> for example. (All of this can be customized via the API in a number of places, if you don't want to use the default values and that specific <code>SSLContext</code>s for a given purpose.)</p> <p>The difference between the <code>KeyManager</code> and <code>TrustManager</code> (and thus between <code>javax.net.ssl.keyStore</code> and <code>javax.net.ssl.trustStore</code>) is as follows (quoted from the <a href="http://download.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#RelsTM_KM">JSSE ref guide</a>):</p> <blockquote> <p>TrustManager: Determines whether the remote authentication credentials (and thus the connection) should be trusted.</p> <p>KeyManager: Determines which authentication credentials to send to the remote host.</p> </blockquote> <p>(Other parameters are available and their default values are described in the <a href="http://download.oracle.com/javase/6/docs/technotes/guides/security/jsse/JSSERefGuide.html#Customization">JSSE ref guide</a>. Note that while there is a default value for the trust store, there isn't one for the key store.)</p> <p>Essentially, the keystore in <code>javax.net.ssl.keyStore</code> is meant to contain your private keys and certificates, whereas the <code>javax.net.ssl.trustStore</code> is meant to contain the CA certificates you're willing to trust when a remote party presents its certificate. In some cases, they can be one and the same store, although it's often better practice to use distinct stores (especially when they're file-based).</p> |

8,378,988 | 0 | <p>You can use UDP to multiple servers with the same socket. Probably the simplest way to do it is to have the client assign a session ID to each connection, include the session ID in each datagram it sends, and have the server return that session ID in each reply datagram it sends. Don't use the IP address to distinguish which server the packet is from because a server can have more than one IP address, making it unreliable.</p> <p>Just remember that if you use UDP, you don't get any of the things TCP adds. If you need any of them, you need to do them yourself. If you need all or most of them, TCP is a <em>much</em> better choice.

2,399,368 | 0 | JavaScript: How to determine the web "fold" programmatically? <p><strong>Question:</strong> How can I determine the "fold" programatically (how much vertical content the browser is displaying)?</p> <p>The "fold" defined as where you can no longer see / have to scroll.</p> <p>I've tried with JavaScript to simply determine the browser window size to determine the fold; unfortunately - this doesn't work well because some browsers have tabs, etc and even though you might have 2 browsers windows at the same size - each browser might be <em>displaying</em> a different vertical size of content.</p> |
16,712,760 | 0 | <p>I tried ButtonCell solution too. But if you click in a cell who as no button then an error on client side occur:</p> <blockquote> <p>com.google.gwt.core.client.JavaScriptException: (TypeError) @com.google.gwt.core.client.impl.Impl::apply(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)([JavaScript object(445), JavaScript object(240), JavaScript object(637)]): parent is null</p> </blockquote> <p>So I added this to override the Event and avoid Event if I want:</p> <pre><code> @Override public void onBrowserEvent(com.google.gwt.cell.client.Cell.Context context, Element parent, YourObject object, NativeEvent event) { if (object.isCompleted()) super.onBrowserEvent( context, parent, object, event); } </code></pre> <p>I don't know if it's the better way to do it but it works.</p> |
