  • Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

    - by LucasTizma
    I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

  • WF 4.0 can't get to resume workflow on the staging/production environment

    - by Yasmine Atta Hajjaj
    I have developed various registeration workflows using WF4.0. Each work flow has various bookmarks. I am using the registeration wf for an asp.net application. I tested the asp.net application locally and it is working fine( Starting WF, Persisting to db and resuming bookmarks). When I try to test it on the staging server, everything goes messy. I can no longer resume wfs and I get an error message : System.Runtime.DurableInstancing.InstancePersistenceCommandException was unhandled by user code Message=The execution of the InstancePersistenceCommand named {urn:schemas-microsoft-com:System.Activities.Persistence/command}LoadWorkflow was interrupted by an error.

I enabled it on the staging server , I installed application server on the staging server and I am still getting the same error. I would appreciate if anyone could help with the problem. Thanks in advance :)

  • How to solve "catastrophic failure" with 32-bit COM component in SysWOW64\cscript or wscript

    - by kcrumley
    I'm trying to run a VBScript script that uses a 7-year-old 3rd-party 32-bit COM component on Windows Server 2008 R2, with the command-line 32-bit script host, SysWOW64\cscript.exe. When I call CreateObject on the class, it appears to be successful, but the very first time I try to use a property or method (I've tried several different ones) on the object, it gives me the "catastrophic failure". I have identical results with SysWOW64\wscript.exe, except, of course, that my error message comes in a msgbox instead of the command-line window. I think this has to do specifically with the 64-bit scripting hosts because of the following: The equivalent Classic ASP script, calling the same component and using 95% of the same code, works correctly on the same server, with IIS configured to support 32-bit COM. The same VBScript works correctly on a 32-bit Windows XP machine and a 32-bit Windows Server 2003 machine. The component fails in exactly the same way on my 64-bit Windows 7 machine. My Google searches for solutions to this problem have mostly turned up a lot of different problems that were solved by putting the COM component into a toolbar in Visual Studio. Obviously, that solution doesn't apply here. My questions are: Is there a core problem that is always behind a "catastrophic failure" from a Windows scripting host calling a COM component? Is there a place in a configuration snap-in, or in the registry, where I need to make a change similar to the change I had to make to the IIS Application pool to "Enable 32-bit Applications"? Is there a general place in the Server 2008 R2 Event Viewer that I should be looking, to see if there are any more details on the failure, in case it turns out to be specific to this component? Thanks in advance.

  • How to upload images from iPhone app developed using Titanium

    - by Karthik.K
    Hi, I finally landed up in developing an iPhone app using Titanium Mobile. Now the problem I face is, Im able to run the app, and the app also sends the image to the server. But Im not able to see the file that got uploaded to the server. I have pasted the iPhone app's code to send image to the server and also, the PHP file that would receive the file from the app. var win = Titanium.UI.currentWindow; var ind=Titanium.UI.createProgressBar({ width:200, height:50, min:0, max:1, value:0, style:Titanium.UI.iPhone.ProgressBarStyle.PLAIN, top:10, message:'Uploading Image', font:{fontSize:12, fontWeight:'bold'}, color:'#888' }); win.add(ind); ind.show(); Titanium.Media.openPhotoGallery({ success:function(event) { Ti.API.info("success! event: " + JSON.stringify(event)); var image = event.media; var xhr = Titanium.Network.createHTTPClient(); xhr.onerror = function(e) { Ti.API.info('IN ERROR ' + e.error); }; xhr.onload = function() { Ti.API.info('IN ONLOAD ' + this.status + ' readyState ' + this.readyState); }; xhr.onsendstream = function(e) { ind.value = e.progress ; Ti.API.info('ONSENDSTREAM - PROGRESS: ' + e.progress+' '+this.status+' '+this.readyState); }; // open the client xhr.open('POST','http://www.myserver.com/tmp/upload2.php'); xhr.setRequestHeader("Connection", "close"); // send the data xhr.send({media:image}); }, cancel:function() { }, error:function(error) { }, allowImageEditing:true }); And here is the PHP code on the server: http://www.pastie.org/891050 I'm not sure where I'm going wrong. Please help me out in this issue. Would love to provide if you need some more information.

  • WCF Http Bindings, Require SSL

    - by JoshKraker
    I have the following binding I'm using with my wsHttpBinding webservice. <binding name="wsHttpConfig"> <security> <transport clientCredentialType="None"/> </security> </binding> The issue is that it allows for the client to connect using either Http or Https. I would like to require them to use SSL. I tried adding the following: <system.web.extensions> <scripting> <webServices> <authenticationService enabled="true" requireSSL = "true"/> </webServices> </scripting> </system.web.extensions> But it had no effect; client could still connect with Http. I then tried checking the "Require SSL" in the IIS7 SSL Settings and had client certificates radio set to Accept. Now, when I try to view the service I am getting the error "Could not find a base address that matches scheme http for the endpoint with binding WSHttpBinding. Registered base address schemes are [https]." Anyone know exactly how to fix this error? I have been googling for the last 3 hours trying 500 different combinations (not 500, but too many to list) and could not get anything to run.

  • File permissions with FileSystemObject - CScript.exe says one thing, Classic ASP says another...

    - by Dylan Beattie
    I have a classic ASP page - written in JScript - that's using Scripting.FileSystemObject to save files to a network share - and it's not working. ("Permission denied") The ASP page is running under IIS using Windows authentication, with impersonation enabled. If I run the following block of code locally via CScript.exe: var objNet = new ActiveXObject("WScript.Network"); WScript.Echo(objNet.ComputerName); WScript.Echo(objNet.UserName); WScript.Echo(objNet.UserDomain); var fso = new ActiveXObject("Scripting.FileSystemObject"); var path = "\\\\myserver\\my_share\\some_path"; if (fso.FolderExists(path)) { WScript.Echo("Yes"); } else { WScript.Echo("No"); } I get the (expected) output: MY_COMPUTER dylan.beattie MYDOMAIN Yes If I run the same code as part of a .ASP page, substituting Response.Write for WScript.Echo I get this output: MY_COMPUTER dylan.beattie MYDOMAIN No Now - my understanding is that the WScript.Network object will retrieve the current security credentials of the thread that's actually running the code. If this is correct - then why is the same user, on the same domain, getting different results from CScript.exe vs ASP? If my ASP code is running as dylan.beattie, then why can't I see the network share? And if it's not running as dylan.beattie, why does WScript.Network think it is?

  • Spring MVC parameter validation

    - by Don
    Hi, I've defined a controller, validator and command class for a Spring 2.5 MVC application like this: public class ResourceController extends AbstractCommandController { private MessageRetriever messageRetriever; protected ModelAndView handle(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception { ResourceCommand resourceCommand = (ResourceCommand) command; // I NEED TO CHECK HERE IF COMMAND IS VALID? } public static class ResourceCommand { private String module; private String site; private String lang; // GETTERS AND SETTERS OMITTED } public static class ResourceValidator implements Validator { public boolean supports(Class clazz) { return ResourceCommand.class.isAssignableFrom(clazz); } public void validate(Object obj, Errors errors) { ValidationUtils.rejectIfEmptyOrWhitespace(errors, "module", "MODULE_REQUIRED"); ValidationUtils.rejectIfEmptyOrWhitespace(errors, "site", "SITE_REQUIRED"); ValidationUtils.rejectIfEmptyOrWhitespace(errors, "lang", "LANG_REQUIRED"); } } } I have wired these all together in the application context: <bean id="resourceController" class="com.amadeus.jcp.ui.framework.localization.ResourceController"> <property name="commandClass" value="com.amadeus.jcp.ui.framework.localization.ResourceController.ResourceCommand"/> <property name="validator"> <bean class="com.amadeus.jcp.ui.framework.localization.ResourceController.ResourceValidator"/> </property> </bean> However, I can't figure out how to actually check whether the command is valid or not - I assume the framework calls the validator, but how do I get access to the result? Incidentally, I'm using Java 1.4, so can't use any solutions that require annotations or other Java 1.5 features. Thanks, Don

  • How to group strings by prefix

    - by namenlos
    I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls) The situation There are a lot of customers (a thousand for example) If i put all the customers in a single dropdown there's no way it will be easy for a customer to even see all the customers. Also the it will take too long to retireve all the customers from the DB to populate the dropdown My thought is to have two combo box, the first lists groups of the customers by their last name something like a phone book "Aa-Ac", "Ad-Ade", "Adf-B", when selecting the first combo box, it scope the second one to a managable set customer names (no more than for example 40 names) The question I need a reasonable way of grouping their names such that it will be clear to customer which group contains the name. I.e. given a group of names I need to bucketize then int "Aa-Ac". Comments I don't need to solve the general problem of an immense number of names - we know based on our data that 1000 names is the max our users will encounter. If there are other techniques please do share, but I am interested specifically in an answer to my specific question around how to determine the buckets ("Aa-Ac", etc.)

  • Coherent access to mainframe files from Win32 application and IBM RDZ/Eclipse?

    - by Ira Baxter
    I have a suite of tools for processing IBM COBOL source code; these tools are built as Win32 applications and talk to Windows (including network) files using traditional Windows file system calls (open, close, read, write) and work just fine, thank you. I'd like to integrate these with Eclipse; we understand how to get Eclipse to do UI for us we think. The problem is that Eclipse/RDZ users access mainframe files through some IBM magic. In How does RDZ access mainframe files I tried to understand how Eclipse accessed files on a mainframe. Apparantly Eclipse/RDZ has a secret filesystem access backdoor not available to normal mortals. At issue is how our tools, reading some Windows-accessible file (local disk file, NFS to mainframe, ...) can associate such files with the files that Eclipse can access or is using? Ideally we'd like UI-integrated versions of our tools take an Eclipse file-name string for a mainframe file, pass it to our Windows application to process, have the Windows application open/read/process the file, and return results associated with that file to the Eclipse UI. Is there a canonical file name path that would be used with mainframe NFS that would be equivalent to the name or access object the Eclipse RDZ used to access the same file? Are all operations doable internally by Eclipse, doable by the mainframe NFS [for instance, can NFS read/update an element in a partitioned data set? Can Eclipse RDZ? Does it matter?] Is the mainframe file access available to custom Java code running under Eclipse RDZ (e.g., equivalents of open/close/read/write based on filename/path/something?) If so, can somebody steer me towards documentation describing the access methods? Anybody else already solve this problem or have a good suggestion?

Both rely on a jar containing some other classes of mine and is called plugin-dto.jar When the UI plug-in calls a method on one of the classes in the Driver plug-in that returns an object whose class is found in the plugin-dto jar I get the error: java.lang.LinkageError: Class com/test/reporting/NrDsDriverProvider violates loader constraints at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.defineClass(DefaultClassLoader.java:183) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.defineClass(ClasspathManager.java:576) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findClassImpl(ClasspathManager.java:546) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLocalClassImpl(ClasspathManager.java:477) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLocalClass_LockClassLoader(ClasspathManager.java:465) at org.eclipse.osgi.baseadaptor.loader.ClasspathManager.findLocalClass(ClasspathManager.java:445) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.findLocalClass(DefaultClassLoader.java:211) at org.eclipse.osgi.internal.loader.BundleLoader.findLocalClass(BundleLoader.java:381) at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:457) at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:410) at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:398) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:105) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) Any ideas how I get around this issue? Thanks in advance.

  • 'License expired' error when dynamically generating Excel docs in ASP.NET

    - by Mac
    Anyone familiar with error below? When I run my webapp to generate a dynamic excel doc from my local machine it works fine but when the same piece of code is invoked on the server I get the below error.

  • Hopping from a C++ to a Perl/Unix job

    - by rocknroll
    Hi all, I have been a C++ / Linux Developer till now and I am adept in this stack. Of late I have been getting opportunities that require Perl, Unix (with knowledge of C++,shell scripting) expertise. Organizations are showing interest even though I don't have much scripting experience to boast off. The role is more in a Support, maintenance project involving SQL as well. Off late I am in a fix whether to forgo these offers or not. I don't know the dynamics of an IT organization and thus on one hand I fear that my C++ experience will be nullified and on the positive side I am getting to work on a new technology stack which will only add to my skill set. I am sure, most of you at some point of time have encountered such dilemmas and would have taken some decision. I want you to share your perspectives on such a scenario where a person is required to change his/her technology stack when changing his/her job. What are the merits and demerits in going with either of the choices? Also I know that C++ isn't going anywhere in the near future. What about perl? I have no clue as to what the future holds for perl developer? Whether there are enough opportunities for a perl developer? I am asking this question here because most of my fellow programmers face this career choice dilemma. Thanks.

  • JQueryUI with Google's CDN help

    - by TenaciousImpy
    Hi, I'm having trouble loading JQueryUI from Google's CDN. I've got an ASP.NET application that and am using this to call the scripts: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js" type="text/javascript"></script> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/ui-darkness/jquery-ui.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> $(function() { $("#accordion").accordion(); }); </script> </asp:Content> I then have a test accordion: <div id="accordion"> <h3><a href="#">First header</a></h3> <div>First content</div> <h3><a href="#">Second header</a></h3> <div>Second content</div> </div> However, this doesn't work. I used Chrome's Dev tool and I get this error: Uncaught Error: The 'accordion' plugin requires Sys.scripts.ExtendedAccordion to be loaded with a call to Sys.require() first I'm also using MS' Ajax CDN in my masterpage, so could that be causing a problem? Thanks

  • ScriptingBridge causes iTunes to relaunch after quit

    - by Justin Voss
    I'm working on a Cocoa app that monitors what you're listening to in iTunes, and since I'm targeting Mac OS 10.5 and higher, I've decided to use Scripting Bridge. If I try to close iTunes too close to the time that my app polls it for the current track, iTunes will immediately relaunch! The only way to reliably prevent this behavior is to quit my app first, then quit iTunes. Switching to EyeTunes solves the problem, but it's a fairly old codebase and I was hoping that I could accomplish this without an external library. Surely I'm doing something wrong that's causing the relaunch? Here's some sample code; this snippet is run every few seconds, triggered by an NSTimer. #import "iTunesBridge.h" // auto-generated according to Apple's docs -(void)updateTrackInfo { iTunesApplication *iTunes = [[SBApplication alloc] initWithBundleIdentifier:@"com.apple.iTunes"]; iTunesTrack *currentTrack = [iTunes currentTrack]; // inspect currentTrack to determine what's being played... [iTunes release]; } Is this a known issue with Scripting Bridge, or am I using it incorrectly?

  • Extension methods in class library project

    - by Mostafa
    I've implemented some extension methods and put those in separate Class Library project. Imagine I have a simple extension method like this in class library called MD.Utility: namespace MD.Utility { public static class ExtenMethods { public static bool IsValidEmailAddress(this string s) { Regex regex = new Regex(@"^[\w-\.]+@([\w-]+\.)+[\w-]{2,4}$"); return regex.IsMatch(s); } } } But nowhere in WebApp like App_code folder or WebFroms code-behind page I can't use this Extension method. If I do like this: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using MD.Utility; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string email = "[email protected]"; if (email.IsValidEmailAddress()) { //To do } } } The compiler doesn't recognize IsValidEmailAddress() and even no intellisense support. While if I put my extension method in App_Code folder it's ok for using in another cs file in App_code Folder or Web Form code-behind pages.

  • Android Loading listview items from service results in hang

    - by Isaac Waller
    Hello, In my Android application, I have a ListActivity. This ListActivity uses a SimpleAdapter that I fill with items from my service. So, in my code, I do: MySuperCoolService.Binder serviceBinder = null; private ServiceConnection serviceConnection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder service) { Log.d(TAG, "Service connection: connected!"); serviceBinder = (MySuperCoolService.Binder)service; } public void onServiceDisconnected(ComponentName className) { Log.d(TAG, "Service connection: disconnected"); serviceBinder = null; } }; bindService(new Intent(this, MySuperCoolService.class), serviceConnection, BIND_AUTO_CREATE); while(serviceBinder==null) { Thread.Sleep(1000); } // now retrieve from service using binder and set list adapter This whole operation takes hardly any time (less than a second), so I want it to run in the UI thread. See my onCreate: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); fillDataUsingCodeAbove(); } The reason I want this to run in the UI thread is that if you have a list item selected, or you have scrolled to a certain position in the ListView, and you rotate the device or take out the keyboard or something (to trigger a configuration change) when my activity is restarted, Android will try to restore the state right after onCreate. But, if I run it in a separate thread, it will not. Also there is a cool fadein animation too :) The problem I am having with running it in the UI thread is that when I try to bind to the service, that service bind request gets put onto the message queue. But then when I go into my loop, I stop the message queue from looping. So my program hangs, because it's waiting for the service to get bound, and the service won't get bound until the loop ends. I have thought of putting Looper.loop() inside my loop, but that just hangs it at Looper.loop() (I don't know why.) Sorry for such a long question, Isaac Waller

  • Best Pattern for AllowUnsafeUpdates

    - by webwires
    So far, in my research I have seen that it is unwise to set AllowUnsafeUpdates on GET request operation to avoid cross site scripting. But, if it is required to allow this, what is the proper way to handle the situation to mitigate any exposure? Here is my best first guess on a reliable pattern if you absolutely need to allow web or site updates on a GET request. Best Practice? protected override void OnLoad(System.EventArgs e) { if(Request.HttpMethod == "POST") { SPUtility.ValidateFormDigest(); // will automatically set AllowSafeUpdates to true } // If not a POST then AllowUnsafeUpdates should be used only // at the point of update and reset immediately after finished // NOTE: Is this true? How is cross-site scripting used on GET // and what mitigates the vulnerability? } // Point of item update SPSecurity.RunWithElevatedPrivledges(delegate() { using(SPSite site = new SPSite(SPContext.Current.Site.Url)) { using (SPWeb web = site.RootWeb) { bool allowUpdates = web.AllowUnsafeUpdates; //store original value web.AllowUnsafeUpdates = true; //... Do something and call Update() ... web.AllowUnsafeUpdates = allowUpdates; //restore original value } } }); Feedback on the best pattern is appreciated.

  • Loading and binding a serialized view model to a WPF window?

    - by generalt
    Hello all. I'm writing a one-window UI for a simple ETL tool. The UI consists of the window, the code behind for the window, a view model for the window, and the business logic. I wanted to provide functionality to the users to save the state of the UI because the content of about 10-12 text boxes will be reused between sessions, but are specific to the user. I figured I could serialize the view model, which contains all the data from the textboxes, and this works fine, but I'm having trouble loading the information in the serialized XML file back into the text boxes. Constructor of window: public ETLWindow() { InitializeComponent(); _viewModel = new ViewModel(); this.DataContext = _viewModel; _viewModel.State = Constants.STATE_IDLE; Loaded += new RoutedEventHandler(MainWindow_Loaded); } XAML: <TextBox x:Name="targetDirectory" IsReadOnly="true" Text="{Binding TargetDatabaseDirectory, UpdateSourceTrigger=PropertyChanged}"/> ViewModel corresponding property: private string _targetDatabaseDirectory; [XmlElement()] public string TargetDatabaseDirectory { get { return _targetDatabaseDirectory; } set { _targetDatabaseDirectory = value; OnPropertyChanged(DataUtilities.General.Utilities.GetPropertyName(() => new ViewModel().TargetDatabaseDirectory)); } Load event in code behind: private void loadState_Click(object sender, RoutedEventArgs e) { string statePath = this.getFilePath(); _viewModel = ViewModel.LoadModel(statePath); } As you can guess, the LoadModel method deserializes the serialized file on the user's drive. I couldn't find much on the web regarding this issue. I know this probably has something to do with my bindings. Is there some way to refresh on the bindings on the XAML after I deserialize the view model? Or perhaps refresh all properties on the view model? Or am I completely insane thinking any of this could be done? Thanks.
