  • iPhone UIButton Tap

    - by Ivan
    Hello all, I am trying to make a button that response to single and double tap. I am trying to do this using myAction method. The problem is that first time when I press the button the method myAction isn't called. Can somebody tell why this happening and how can I fix that? -(IBAction)myButton:(id)sender{ UIButton *theButton = (UIButton *)sender; [theButton addTarget:self action:@selector(myAction:forEvent:) forControlEvents:UIControlEventAllEvents]; } - (void)myAction:(id)sender forEvent:(UIEvent *)event { NSLog(@"Touch events goes here"); } Thank you, I.

  • Trying to compile MobileSubstrate addon - Undefined symbol

    - by eWolf
    Hi! I went through this tutorial to create a MobileSubstrate addon. I could compile the example hook without errors. But as soon as I add #import <SpringBoard/SBAwayController.h> in ExampleHookProtocol.h and SBAwayController *awayController = [SBAwayController sharedAwayController]; in ExampleHookLibrary.mm (as the first line of the __$ExampleHook_AppIcon_Launch function) I get the following error message when attempting to make (triggered by the latter change): Undefined symbols: "_OBJC_CLASS_$_SBAwayController", referenced from: __objc_classrefs__DATA@0 in ExampleHookLibrary.o ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [ExampleHook.dylib] Error 1. The header file for SBAwayController is located in /var/toolchain/sys30/usr/include/SpringBoard, just like SBApplicationIcon.h, which is used by the ExampleHook. I'm compiling on my iPod touch 2G. Can anyone help me? Thanks in advance, Eric

  • Eclipse (Springsource Tool Suite 2.3.1) can't resolve dependencies for classes in the same package

    - by Steve
    This started happening when I upgraded my Springsource Toolsuite from 2.3 to 2.3.1. Essentially whenever I do anything, such as open a file, change a file, etc, I have to do a clean. Everything works fine when I do mvn commands on the command line, which leads me to believe that Eclipse is looking in the wrong place for compiled code or something along those lines, although that is entirely superstitious at this point. Example: I make a change to com.foo.mypackage.MyClass. Suddenly a bunch of tests that excercise MyClass get the red x - for class not found! In src/main/test: com.foo.DbUnitTest com.foo.mypackage.FooTest extends DbUnitTest DbUnitTest gets a class not found. I do a clean, and everything is fine. I touch something, and it breaks again :(. I don't really know where to begin on how to troubleshoot this.

  • In Perl, how can a subroutine get a coderef that points to itself?

    - by hillu
    For learning purposes, I am toying around with the idea of building event-driven programs in Perl and noticed that it might be nice if a subroutine that was registered as an event handler could, on failure, just schedule another call to itself for a later time. So far, I have come up with something like this: my $cb; my $try = 3; $cb = sub { my $rc = do_stuff(); if (!$rc && --$try) { schedule_event($cb, 10); # schedule $cb to be called in 10 seconds } else { do_other_stuff; } }; schedule_event($cb, 0); # schedule initial call to $cb to be performed ASAP Is there a way that code inside the sub can access the coderef to that sub so I could do without using an extra variable? I'd like to schedule the initial call like this. schedule_event( sub { ... }, 0); I first thought of using caller(0)[3], but this only gives me a function name, (__ANON__ if there's no name), not a code reference that has a pad attached to it.

  • using EventToCommand & PassEventArgsToCommand :: how to get sender, or better metaphor?

    - by JoeBrockhaus
    The point of what I'm doing is that there are a lot of things that need to happen in the viewmodel, but when the view has been loaded, not on constructor. I could wire up event handlers and send messages, but that just seems kinda sloppy to me. I'm implementing a base view and base viewmodel where this logic is contained so all my views get it by default, hopefully. Perhaps I can't even get what I'm wanting: the sender. I just figured this is what RoutedEventArgs.OriginalSource was supposed to be? [Edit] In the meantime, I've hooked up an EventHandler in the xaml.cs, and sure enough, OriginalSource is null there as well. So I guess really I need to know if it's possible to get a reference to the view/sender in the Command as well? [/Edit] My implementation requires that a helper class to my viewmodels which is responsible for creating 'windows' knows of the 'host' control that all the windows get added to. i'm open to suggestions for accomplishing this outside the scope of using eventtocommand. :) (the code for Unloaded is the same) #region ViewLoadedCommand private RelayCommand<RoutedEventArgs> _viewLoadedCommand = null; /// <summary> /// Command to handle the control's Loaded event. /// </summary> public RelayCommand<RoutedEventArgs> ViewLoadedCommand { get { // lazy-instantiate the RelayCommand on first usage if (_viewLoadedCommand == null) { _viewLoadedCommand = new RelayCommand<RoutedEventArgs>( e => this.OnViewLoadedCommand(e)); } return _viewLoadedCommand; } } #endregion ViewLoadedCommand #region View EventHandlers protected virtual void OnViewLoadedCommand(RoutedEventArgs e) { EventHandler handler = ViewLoaded; if (handler != null) { handler(this, e); } } #endregion

  • JTree events seem misordered

    - by MeBigFatGuy
    It appears to me that tree selection events should happen after focus events, but this doesn't seem to be the case. Assume you have a JTree and a JTextField, where the JTextField is populated by what is selected in the tree. When the user changes the text field, on focus lost, you update the tree from the text field. however, the tree selection is changed before the focus is lost on the text field. this is incorrect, right? Any ideas? Here is some sample code: import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.event.*; public class Focus extends JFrame { public static void main(String[] args) { Focus f = new Focus(); f.setLocationRelativeTo(null); f.setVisible(true); } public Focus() { Container cp = getContentPane(); cp.setLayout(new BorderLayout()); final JTextArea ta = new JTextArea(5, 10); cp.add(new JScrollPane(ta), BorderLayout.SOUTH); JSplitPane sp = new JSplitPane(); cp.add(sp, BorderLayout.CENTER); JTree t = new JTree(); t.addTreeSelectionListener(new TreeSelectionListener() { public void valueChanged(TreeSelectionEvent tse) { ta.append("Tree Selection changed\n"); } }); t.addFocusListener(new FocusListener() { public void focusGained(FocusEvent fe) { ta.append("Tree focus gained\n"); } public void focusLost(FocusEvent fe) { ta.append("Tree focus lost\n"); } }); sp.setLeftComponent(new JScrollPane(t)); JTextField f = new JTextField(10); sp.setRightComponent(f); pack(); f.addFocusListener(new FocusListener() { public void focusGained(FocusEvent fe) { ta.append("Text field focus gained\n"); } public void focusLost(FocusEvent fe) { ta.append("Text field focus lost\n"); } }); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

  • Daemon program that uses select() inside infinite loop uses significantly more CPU when ported from

    - by Jake
    I have a daemon app written in C and is currently running with no known issues on a Solaris 10 machine. I am in the process of porting it over to Linux. I have had to make minimal changes. During testing it passes all test cases. There are no issues with its functionality. However, when I view its CPU usage when 'idle' on my Solaris machine it is using around .03% CPU. On the Virtual Machine running Red Hat Enterprise Linux 4.8 that same process uses all available CPU (usually somewhere in the 90%+ range). My first thought was that something must be wrong with the event loop. The event loop is an infinite loop ( while(1) ) with a call to select(). The timeval is setup so that timeval.tv_sec = 0 and timeval.tv_usec = 1000. This seems reasonable enough for what the process is doing. As a test I bumped the timeval.tv_sec to 1. Even after doing that I saw the same issue. Is there something I am missing about how select works on Linux vs. Unix? Or does it work differently with and OS running on a Virtual Machine? Or maybe there is something else I am missing entirely? One more thing I am sure sure which version of vmware server is being used. It was just updated about a month ago though. Thanks.

  • Not possible to load DropDownList on FormView from code behind??

    - by tbone
    I have a UserControl, containing a FormView, containing a DropDownList. The FormView is bound to a data control. Like so: <asp:FormView ID="frmEdit" DataKeyNames="MetricCode" runat="server" DefaultMode="Edit" DataSourceID="llbDataSource" Cellpadding="0" > <EditItemTemplate> <asp:DropDownList ID="ParentMetricCode" runat="server" SelectedValue='<%# Bind("ParentMetricCode") %>' /> etc, etc I am trying to populate the DropDownList from the codebehind. If this was not contained in a FormView, I would normally just do it in the Page_Load event. However, that does not work within a FormView, as as soon as I try to do it, accessing the dropdownlist in code, ie: theListcontrol = CType(formView.FindControl(listControlName), System.Web.UI.WebControls.ListControl) ...the data binding mechansim of the FormView is invoked, which, of course, tries to bind the DropDownList to the underlying datasource, causing a *'ParentMetricCode' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value * error, since the DropDownList has not yet been populated. I tried performing the load in the DataBinding() event of the FormView, but then: theListcontrol = CType(formView.FindControl(listControlName), System.Web.UI.WebControls.ListControl) ...fails, as the FormView.Controls.Count = 0 at that point. Is this impossible? (I do not want to have to use a secondary ObjectDataSource to bind the dropdownlist to)

  • UIButtons work when rotated right, but not when rotated left. Huh?

    - by Ben Collins
    I have a view that is added to the current view when the device is rotated to a LandscapeLeft or LandscapeRight orientation. This view has 4 buttons on it that are all connected to outlets and each have the "touch up inside" event hooked up to the same action. If rotated to a LandscapeLeft orientation, I transform my added view to rotate -90 degrees, and everything works fine. If rotated to a LandscapeRight orientation, I transform the added view to rotate 90 degrees, and the buttons don't work! Highlighting doesn't happen, and the action isn't called. I am at a bit of a loss as to why this might be. Any ideas?

  • XML: Check if anything exists between two nodes

    - by sebastian
    Hi there, I need to find out if anything exists between two nodes. My XML looks like this: <event value1="1" value2="2" value3="3" <info="some info here"/> Line 1.</lb> Line 2.</lb></lb> Line 3.</lb> Line 4.</lb> </event> My goal is to convert the </lb> nodes to </br> HTML tags using XSLT. There is one additional requirement to fulfill though. In case there is one </lb> directly following another </lb> I want to output only one </br>. My XSLT looks like this: <xsl:template match="lb"> <xsl:if test="not(preceding-sibling::lb[1])"> <br/> </xsl:if> </xsl:template> The problem with the XSLT above is that it works correctly for line 1 only as the text between both nodes is ignored. Maybe someone here can help.

  • jQuery + Jeditable - detect when select is changed

    - by Bryan Roth
    I'm using Jeditable for in-place editing. One the controls I am working with has the select type. When a user clicks on the field, the following select control is generated: <div id="status" class="editable_select"> <form> <select name="value"> <option value="Active">Active</option> <option value="Inactive">Inactive</option> </select> <button type="submit">Save</button> <button type="cancel">Cancel</button> </form> </div> What I am trying to figure out is how to use jQuery to detect when that select control is changed, especially since it doesn't have an ID attribute. This is what I have so far, but the event is not getting triggered: $(document).ready(function () { $('#status select').change(function () { alert("Change Event Triggered On:" + $(this).attr("value")); }); });

  • What is the difference between #ifdef __IPHONE_3.2 and #if __IPHONE_3.2?

    - by Jonathan
    Hi, I have an iphone app that needs to work for 3.1.3 for the iPhone and 3.2 for the iPad. It is an iPhone app that I want to work on the iPad. The main difference is the MPMoviePlayerController which introduces/and deprecates lots of things in 3.2. Since, the iPhone OS only goes up to 3.1.3 and the iPad is on 3.2, I need to seperate my code so it only compiles the required code for the respective OS. I can't use [[UIDevice currentDevice] model] because I end up with deprecated warnings on the 3.1.3 code. Also, UIUserInterfaceIdiomPad is new in 3.2 so it doesn't work well with 3.1.3... So, I decided to use this, which only compiles what is necessary for the particular OS: #if __IPHONE _3_2 //do 3.2 iPad stuff #else //do 3.1.3 iPhone/iPod Touch stuff #endif My question is... What is the difference between these? #ifdef __IPHONE_3_2 and #if __IPHONE_3_2 Thank you

  • Resizing window causes black strips

    - by Paja
    I have a form, which sets these styles in constructor: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); And I draw some rectangles in Paint event. There are no controls on the form. Hovewer, when I resize the form, there are black strips at right and bottom of the form. Is there any way to get rid of them? I've tried everything, listening for WM_ERASEBKGND in WndProc, manually drawing the form on WM_PAINT, implementing custom double buffer, etc. Is there anything else I could try? I've found this: https://connect.microsoft.com/VisualStudio/feedback/details/522441/custom-resizing-of-system-windows-window-flickers and it looks like it is a bug in DWM, but I just hope I can do some workaround. Please note that I must use double buffering, since I want to draw pretty intense graphic presentation in the Paint event. I develop in C# .NET 2.0, Win7.

  • Flash As3 Mute Button problems

    Hey guys, I am trying to create a UI movie clip that can be used across different scenes. It uses variables from the root scope to determine states. When i press the mute button is works fine, however when i try to un-mute things go weird. Sometimes it takes 2 clicks to unmute, sometimes more. It seems random. Muting however seems to work first time.. Any ideas? Main Timeline: var mute:Boolean = false; var playerName = "Fred"; function setMute(vol) { var sTransform:SoundTransform = new SoundTransform(1,0); sTransform.volume = vol; SoundMixer.soundTransform = sTransform; } function toggleMuteBtn(event:Event) { if (mute) { // Sound On, Mute Off mute = false; setMute(1); ui_mc.muteCross_mc.visible = false; } else { // Sound Off, Mute On mute = true; setMute(0); ui_mc.muteCross_mc.visible = true; } } ui_mc Action Script: if (MovieClip(parent).mute == false) { muteCross_mc.visible = false; } mute_btn.addEventListener(MouseEvent.CLICK, MovieClip(parent).toggleMuteBtn);

  • Pressing back button in ActivityGroup causes it to pause, and then continue shutting down the next t

    - by synic
    Pressing the back button causes onPause to be called, and the app stays paused until it is re-launched by clicking on the icon, at which point, onDestroy gets called, and the main activity continues to shut down. Simple class to demonstrate. Note, as far as I can tell, this only happens on the Nexus One. I can't reproduce it in the emulator or on my Droid. package com.vimtips.testshutdown; import android.app.ActivityGroup; import android.os.Bundle; import android.util.Log; import android.view.KeyEvent; public class MainActivity extends ActivityGroup { private static final String TAG = "MainActivity"; private int counter = 3; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode == KeyEvent.KEYCODE_BACK) { if(counter-- > 0) return true; } return super.onKeyDown(keyCode, event); } @Override public void onPause() { super.onPause(); Log.d(TAG, "onPause called"); } @Override public void onDestroy() { super.onDestroy(); if(isFinishing()) { Log.d(TAG, "Shutting down"); } } } And here's the log: I/ActivityManager( 132): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10100000 cmp=com.vimtips.testshutdown/.MainActivity } I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 305 ms (total 305 ms) D/MainActivity( 1393): onPause called I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 302 ms (total 302 ms) D/MainActivity( 1393): Shutting down This doesn't appear to happen on a normal Activity, just an Activity group, though looking at Android's sourcecode, I can't figure out why. It's causing some serious problems with my app. Anyone know why this would happen?

  • How to handle data output in an Observer?

    - by Mannaz
    I have an Observable and an Observer. The observable does download some stuff in a background thread and calls notifyObservers to let the observers read the status. At some point in public void update the observer tries to updates the GUI ((TextView)findViewById('R.id.foo')).setText("bar"); but it seems like the observable thread calls this method, because the Observable (!!!) throws this: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. at android.view.ViewRoot.checkThread(ViewRoot.java:2462) at android.view.ViewRoot.requestLayout(ViewRoot.java:512) ... at com.mynamespace.acitivty.TrackActivity.startPlay(TrackActivity.java:72) at com.mynamespace.acitivty.TrackActivity.update(TrackActivity.java:107) at java.util.Observable.notifyObservers(Observable.java:147) at java.util.Observable.notifyObservers(Observable.java:128) at com.mynamespace.module.communication.Download.stateChanged(Download.java:213) at com.mynamespace.module.communication.Download.run(Download.java:186) at java.lang.Thread.run(Thread.java:1058) Is there some way I can prevent this from happening?

  • Differences in ansychronous VB.NET and C#???

    - by Jim Beam
    So I've been posting this week for help with an API that has asynchronous calls. You can view the CODE here: http://stackoverflow.com/questions/2638920/c-asynchronous-event-procedure-does-not-fire With a little more digging, I found out that the API is written in VB.NET and I created a VB.NET example and guess what . . . the asynchronous calls work like a charm. So, now I need to find out why the calls are not firing in the C# code I have. The API being written in VB really shouldn't matter, but again, the VB.NET code works and my C# does not. Is there a problem with the event handler and hows its being declared that causes it to not fire? UPDATE VB Code added Imports ClientSocketServices Imports DHS_Commands Imports DHS Imports Utility Imports SocketServices Class Window1 Public WithEvents AppServer As New ClientAppServer Public Token As LoginToken Private Sub login() Dim handler As New LoginHandler Token = handler.RequestLogin("admin", "admin", localPort:=12000, serverAddress:="127.0.0.1", serverLoginPort:=11000, clienttype:=LoginToken.eClientType.Client_Admin, timeoutInSeconds:=20) If Token.Authenticated Then AppServer = New ClientAppServer(Token, True) AppServer.RetrieveCollection(GetType(Gateways)) End If End Sub Private Sub ReceiveMessage(ByVal rr As RemoteRequest) Handles AppServer.ReceiveRequest If TypeOf (rr.TransferObject) Is Gateways Then MsgBox("dd") End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click login() End Sub End Class

  • SignalR - Handling disconnected users

    - by guilhermeGeek
    Hy, I'm using the signalR library on a project to handle an notification and chat modules. I've a table on an database to keep a track of online users. The HUB for chat is inheriting IDisconnect where i disconnect the user. After disconnecting the user, i warm the users about that event. At this point, i check if the disconnect user is the client. If it's, then i call an method on HUB to reconnect the user (just update the table). I do this because with the current implementation, once the user closes a tab on the browser it calls the Disconnect task but he could have another tab opened. I've not tested (with larger requests) this module yet, but on my development server it could take a few seconds between the IDisconnect event, and the request from the user to connect again. I'm concerned with my implementation to handle disconnected users from the chat but i can't see another way to improve this. If possible, could someone give me a advice on this, or this is the only solution that i've?
