  • Can I Specify Strings for MySql Table Values?

    - by afterimagedesign
    I have a MySql table that stores the users state and city from a list of states and cities. I specifically coded each state as their two letter shortened version (like WA for Washington and CA for California) and every city has the two letter abbreviation and the city name formated like this: Boulder Colorado would be CO-boulder and Salt Lake City, Utah would be UT-salt-lake-city as to avoid different states with same city name. The PHP inserts the value (UT-salt-lake-city) under the column City, but when I call the variable through PHP, it displays like this: Your location is: UT-salt-lake-city, Utah. To solve this, I've been making this list of variables if ($city == "AL-auburn") { $city = "Auburn"; } else if ($city == "AL-birmingham") { $city = "Birmingham"; } else if ($city == "GA-columbus") { $city = "Columbus"; $state = "Georgia"; } else if ($city == "AL-dothan") { $city = "Dothan"; } else if ($city == "AL-florence") { $city = "Forence"; } else if ($city == "AL-muscle-shoals") { $city = "Muscle Shoals"; } else if ($city == "AL-gadsden-anniston") { $city = "Gadsden Anniston"; } else if ($city == "AL-huntsville") { $city = "Huntsville"; } else if ($city == "AL-decatur") { $city = "Decatur"; } else if ($city == "AL-mobile") { $city = "Mobile"; } else if ($city == "AL-montgomery") { $city = "Montgomery"; } else if ($city == "AL-tuscaloosa") { $city = "Tuscaloosa"; } Is there a way I can shorten this process or at least call it from a separate file so I don't have to copy/paste every time I want to call the location?

  • Html Select List: why would onchange be called twice?

    - by Mark Redman
    I have a page with a select list (ASP.NET MVC Page) The select list and onchange event specified like this: <%=Html.DropDownList("CompanyID", Model.CompanySelectList, "(select company)", new { @class = "data-entry-field", @onchange = "companySelectListChanged()" })%> The companySelectListChanged function is getting called twice? I am using the nifty code in this question to get the caller. both times the caller is the onchange event, however if i look at the callers caller using: arguments.callee.caller.caller the first call returns some system code as the caller (i presume) and the second call returns undefined. I am checking for undefined to only react once to onchange, but this doesnt seem ideal, whcy would onchange be called twice? UPDATE: ok, found the culprit! ...apart from me :-) but the issue of calling the companySelectListChanged function twice still stands. The onchange event is set directly on the select as mentioned. This calls the companySelectListChanged function. ..notice the 'data-entry-field' class, now in a separate linked javascript file a change event on all fields with this class is bound to a function that changes the colour of the save button. This means there is two events on the onchange, but the companySelectListChanged is called twice? The additional binding is set as follows: $('.data-entry-field').bind('keypress keyup change', function (e) { highLightSaveButtons(); }); Assuming its possible to have 2 change events on the select list, its would assume that setting keypress & keyup events may be breaking something? Any ideas?

  • Slimbox 2 Plugin, jQuery Flickr, and IE8

    - by Nick H.
    Hello, I am currently developing a site that I make use of two jQuery plugins: Flickr jquery plugin (http://code.google.com/p/jquery-flickr/) Slimbox (http://code.google.com/p/slimbox/) The first plugin is used to pull in flickr photos from a specific account. These photos are displayed as thumbnails on the page. I am then using the second plugin to display larger views of these images. Because the flickr photos are fetched when the page loads, I am calling the Slimbox 2 function like this: $(document).ready(function() { $("#Flickr").flickr(); //Call Flickr plugin $(window).bind('load', function() { $("#Flickr a").slimbox();//Call Slimbox2 }); }); On first testing this seemed to have worked perfectly. I tested multiple versions of FireFox, IE7, IE6, and Safari. Everything is great. However, the Slimbox lightbox effest does not work in IE8. However, if I put IE8 into compatibility mode, everything works as expected. I would like to avoid forcing compatibility mode. There are no javascript errors and I am at a loss for testing. Here is a link to a sample: http://www.njhall.com/JRMcCourt-Builders/index.html#ourwork Any advice would be greatly appreciated. Thanks Nick

  • C++ compiler errors in xamltypeinfo.g.cpp

    - by Richard Banks
    I must be missing something obvious but I'm not sure what. I've created a blank C++ metro app and I've just added a model that I will bind to in my UI however I'm getting a range of compiler warnings related to xamltypeinfo.g.cpp and I'm not sure what I've missed. My header file looks like this: #pragma once #include "pch.h" #include "MyColor.h" using namespace Platform; namespace CppDataBinding { [Windows::UI::Xaml::Data::Bindable] public ref class MyColor sealed : Windows::UI::Xaml::Data::INotifyPropertyChanged { public: MyColor(); ~MyColor(); virtual event Windows::UI::Xaml::Data::PropertyChangedEventHandler^ PropertyChanged; property Platform::String^ RedValue { Platform::String^ get() { return _redValue; } void set(Platform::String^ value) { _redValue = value; RaisePropertyChanged("RedValue"); } } protected: void RaisePropertyChanged(Platform::String^ name); private: Platform::String^ _redValue; }; } and my cpp file looks like this: #include "pch.h" #include "MyColor.h" using namespace CppDataBinding; MyColor::MyColor() { } MyColor::~MyColor() { } void MyColor::RaisePropertyChanged(Platform::String^ name) { if (PropertyChanged != nullptr) { PropertyChanged(this, ref new Windows::UI::Xaml::Data::PropertyChangedEventArgs(name)); } } Nothing too tricky, but when I compile I get errors in xamltypeinfo.g.cpp indicating that MyColor is not defined in CppDataBinding. The relevant generated code looks like this: if (typeName == "CppDataBinding.MyColor") { userType = ref new XamlUserType(this, typeName, GetXamlTypeByName("Object")); userType->Activator = ref new XamlTypeInfo::InfoProvider::Activator( []() -> Platform::Object^ { return ref new CppDataBinding::MyColor(); }); userType->AddMemberName("RedValue", "CppDataBinding.MyColor.RedValue"); userType->SetIsBindable(); xamlType = userType; } If I remove the Bindable attribute from MyColor the code compiles. Can someone tell me what blindingly obvious thing I've missed so I can give myself a facepalm and fix the problem?

  • How to clone a Model using Entity Framework and ASP.Net Mvc 2

    - by Picflight
    I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

  • Using Ninject 2.0 with ASP .Net 3.5

    - by GK
    Hi, I am trying to use Ninject 2.0 with Asp .Net 3.5 web application. Following are the DLLS and it's versions I am using. Ninject.dll - v2.0.0.0 Ninject.Extensions.Logging.dll v2.0.0.0 Ninject.Web.dll v1.0.0.0 In my global.ascx.cs I have following method. protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(); kernel.Bind<IDataAccess>().To<DataAccessEntBlock>().InSingletonScope(); return kernel; } When I run the application I get following error. Error activating ILoggerFactory No matching bindings are available, and the type is not self-bindable. Activation path: 1) Request for ILoggerFactory Suggestions: 1) Ensure that you have defined a binding for ILoggerFactory. 2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. 3) Ensure you have not accidentally created more than one kernel. 4) If you are using automatic module loading, ensure the search path and filters are correct. I am not understanding even though I am not trying to register Logger, it seems it is trying to create it's own. How can I resolve this error ? Do I have to use any of the Ninject's extension Logger ? Thanks GK

  • jQuery UI - Close Dialog When Clicked Outside

    - by Sonny
    I have a jQuery UI Dialog that gets displayed when specific elements are clicked. I would like to close the dialog if a click occurs anywhere other than on those triggering elements or the dialog itself. Here's the code for opening the dialog: $(document).ready(function() { var $field_hint = $('<div></div>') .dialog({ autoOpen: false, minHeight: 50, resizable: false, width: 375 }); $('.hint').click(function() { var $hint = $(this); $field_hint.html($hint.html()); $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]); $field_hint.dialog('option', 'title', $hint.siblings('label').html()); $field_hint.dialog('open'); }); /*$(document).click(function() { $field_hint.dialog('close'); });*/ }); If I uncomment the last part, the dialog never opens. I assume it's because the same click that opens the dialog is closing it again. Final Working Code $(document).ready(function() { var $field_hint = $('<div></div>') .dialog({ autoOpen: false, minHeight: 50, resizable: false, width: 375 }) .bind('clickoutside', function(e) { if (!$(e.target).filter('.hint').length) { $field_hint.dialog('close'); } }); $('.hint').click(function() { var $hint = $(this); $field_hint.html($hint.html()); $field_hint.dialog('option', 'position', [162, $hint.offset().top + 25]); $field_hint.dialog('option', 'title', $hint.siblings('label').html()); $field_hint.dialog('open'); }); });

  • Selection Highlight in NSCollectionView

    - by Hooligancat
    On some occasions my head just hurts from banging it against the Cocoa wall. Today is one of those days. I have a working NSCollectionView with one minor, but critical, exception. Getting and highlighting the selected item within the collection. I've had all this working prior to Snow Leopard, but something appears to have changed and I can't quite place my finger on it, so I took my NSCollectionView right back to a basic test and followed Apple's documentation for creating an NSCollectionView here: http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CollectionViews/Introduction/Introduction.html The collection view works fine following the quick start guide. However, this guide doesn't discuss selection other than "There are such features as incorporating image views, setting objects as selectable or not selectable and changing colors if they are selected". Using this as an example I went to the next step of binding the Array Controller to the NSCollectionView with the controller key selectionIndexes, thinking that this would bind any selection I make between the NSCollectionView and the array controller and thus firing off a KVO notification. I also set the NSCollectionView to be selectable in IB. There appears to be no selection delegate for NSCollectionView and unlike most Cocoa UI views, there appears to be no default selected highlight. So my problem really comes down to a related issue, but two distinct questions. How do I capture a selection of an item? How do I show a highlight of an item? NSCollectionView's programming guides seem to be few and far between and most searches via Google appear to pull up pre-Snow Leopard implementations, or use the view in a separate XIB file. For the latter (separate XIB file for the view), I don't see why this should be a pre-requisite otherwise I would have suspected that Apple would not have included the view in the same bundle as the collection view item. I know this is going to be a "can't see the wood for the trees" issue - so I'm prepared for the "doh!" moment. As usual, any and all help much appreciated.

  • How do I use Powershell to print a list of hyperlinks that appear in a Word document?

    - by dwwilson66
    I asked this question last week, and my script cannot find any hyperlinks to change. Now I'm backing up and trying to simply open a single document and list the hyperlinks within. I've verified that the document includes hyperlinks to a number of anchors in the same document, and two hyperlinks to documents in the same directory. However, either Powershell isn't finding links in the doc or I'm outputting the list to the console improperly. Here's my bare-bones code $word = New-Object -ComObject Word.Application $doc ="R:\path\Reporting_Emergency_Or_Hazardous_Situation_-_BC_CC.doc" $hyperlinks = @($doc.Hyperlinks) $hyperlinks $word.quit() or, for line 4 Write-Host $hyperlinks or, again for line 4 $hyperlinks | % {Write-Host $_.address} No errors, just blank results. Not even an object reference to the $hyperlinks array. When I modify line 4 to % $address in $hyperlinks { Write-Host $._address } I get the following error...but it's unclear if I'm trying to read a null array? or if the value is blank. ForEach-Object : Cannot bind parameter 'Process'. Cannot convert the "in" value of type "System.String" to type "System.Management.Automation.ScriptBlock". At F:\path\HyperLinkScrub.ps1:46 char:2 + % <<<< $address in $hyperlinks { + CategoryInfo : InvalidArgument: (:) [ForEach-Object], ParameterBindingException + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.ForEachObjectCommand What am I missing here? I've verified that the Word doc has hyperlinks, and ultimately, I'm trying to diagnose if my script isn't looking for them properly, or if I'm not outputting them to the console properly.

  • How do I load new pages into my current jQuery colorbox?

    - by thinkswan
    I'm having a bit of trouble loading pages into an already-existing colorbox. I have a colorbox opened by clicked a link that is bound by the following code: $("a.ajaxAddPage").colorbox({ onComplete: function(){ $('ul#addPage li a').click(function() { $.fn.colorbox({href: $(this).attr('href')}); return false; }); } }); The following HTML is loaded into that colorbox via AJAX: <div class='colorboxWindow'> <ul id='addPage'> <li><a href='addCat.php'>Add Category</a></li> <li><a href='addPage.php' class='current'>Add New Page</a></li> <li><a href='addPage2.php'>Add Another Page</a></li> </ul> <h3>Add New Page...</h3> </div> I'm trying to have each of those 3 links open in the current colorbox when they are clicked. With my onComplete binding above, this works for the first click, but the next click just opens like a normal page. If I add another onComplete to the $.fn.colorbox() call in the above code, then the 2nd click will also load in the same colorbox, but the 3rd will not. Is there a way to just bind all future clicks to open in the same colorbox? I don't know much about event binding yet. If you need clarification, please ask.

  • How do I get folder size with Exchange Web Services 2010 Managed API?

    - by Adam Tuttle
    I'm attempting to use EWS 2010 Managed API to get the total size of a user's mailbox. I haven't found a web service method to get this data, so I figured I would try to calculate it. I found one seemingly-applicable question on another site about finding mailbox sizes with EWS 2007, but either I'm not understanding what it's asking me to do, or that method just doesn't work with EWS 2010. Noodling around in the code insight, I was able to write what I thought was a method that would traverse the folder structure recursively and result in a combined total for all folders inside the Inbox: private int traverseChildFoldersForSize(Folder f) { int folderSizeSum = 0; if (f.ChildFolderCount > 0) { foreach (Folder c in f.FindFolders(new FolderView(10000))) { folderSizeSum += traverseChildFoldersForSize(c); } } folderSizeSum += (int)f.ManagedFolderInformation.FolderSize; return folderSizeSum; } (Assumes there aren't more than 10,000 folders inside a given folder. Figure that's a safe bet...) Unfortunately, this doesn't work. I'm initiating the recursion with this code: Folder root = Folder.Bind(svc, WellKnownFolderName.Inbox); int totalSize = traverseChildFoldersForSize(root); But a Null Pointer Exception is thrown, essentially saying that [folder].ManagedFolderInformation is a null object reference. For clarity, I also attempted to just get the size of the root folder: Console.Write(root.ManagedFolderInformation.FolderSize.ToString()); Which threw the same NPE exception, so I know that it's not just that once you get to a certain depth in the directory tree that ManagedFolderInformation doesn't exist. Any ideas on how to get the total size of the user's mailbox? Am I barking up the wrong tree?

  • Need help with artificial neural network

    - by deckard cain
    I have an input data for neural network that consists of 2 vectors with 200 elements, that i got from some program for generating signals. So it is actually 2x200 input to my nnet. As target data, i have one 1x200 vector that i also got from the same program. That is my training data set. I gather as much of those sets as i want so i transfer them to matlab and save them as, for example, set1, set2,.... When i am creating neural net, using newfit function (backropagation algorithm and everyhting else is set by default because i am kind of unexperianced with neural nets so i will have to experiment) i'm creating it using set1 only for example. Then, when i am to train neural net i train it for set1 then load set2 and train for it and so on. so its like this function net = create_fit_net(inputs,targets) numHiddenNeurons = 20; net = newfit(inputs,targets,numHiddenNeurons); net=train(net,inputs,targets); load set2; net=train(net,inputs,targets); load set3; net=train(net,inputs,targets); load set4; net=train(net,inputs,targets); i am using 4 sets of data here and all sets have variables of same name and size. My quesion is, am i doing this the right way, because, when doing simulation in some other m file, i am getting bad results, and every time i get different results. Does it matter if i create network with one set and then train with others too, and does it matter what set do i use to train network 1st? Also, i am confused about the amount of neurons to use (im using in the example 20 but actually i tried 1, 10, 30, 50, 100 200 and even 300 and i get nothing). If you have any suggestions, i'd be glad to take them into consideration. Any help is welcome. thanks in advance

  • How can I find the song position of a song being played with XACT?

    - by DJ SymBiotiX
    So I'm making a game in XNA and I need to use XACT for my songs (rather than media player). I need to use XACT because each song will have multiple layers that combine when played at the same time (bass, lead, drums) etc. I cant use the media player because the media player can only play one song at a time. Anyways, so lets say I have a song playing with XACT in my project with the following code public SongController() { audioEngine = new AudioEngine(@"Content\Song1\Song1.xgs"); waveBank = new WaveBank(audioEngine, @"Content\Song1\Layers.xwb"); soundBank = new SoundBank(audioEngine, @"Content\Song1\SongLayers.xsb"); songTime = new PlayTime(); Vox = soundBank.GetCue("Vox"); BG = soundBank.GetCue("BG"); Bass = soundBank.GetCue("Bass"); Lead = soundBank.GetCue("Lead"); Other = soundBank.GetCue("Other"); Vox.SetVariable("CueVolume", 100.0f); BG.SetVariable("CueVolume", 100.0f); Bass.SetVariable("CueVolume", 100.0f); Lead.SetVariable("CueVolume", 100.0f); Other.SetVariable("CueVolume", 100.0f); _bassVol = 100.0f; _voxVol = 100.0f; _leadVol = 100.0f; _otherVol = 100.0f; Vox.Play(); BG.Play(); Bass.Play(); Lead.Play(); Other.Play(); } So when I look at the variables in Vox, or BG (they are Cue's btw) I cant seem to find any play position in them. So I guess the question is: Is there a variable I can query to find that data, or do I need to make my own class that starts counting up from the time I start the song? Thanks

  • How to call SQL Function with multiple parameters from C# web page

    - by Marshall
    I have an MS SQL function that is called with the following syntax: SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = 7 AND LocationName = ''Default'' ', 10) The first parameter passes a specific WHERE clause that is used by the function for one of the internal queries. When I call this function in the front-end C# page, I need to send parameter values for the individual fields inside of the WHERE clause (in this example, both the ClientID & LocationName fields) The current C# code looks like this: String SQLText = "SELECT Field1, COUNT(*) AS RecordCount FROM GetDecileTable('WHERE ClientID = @ClientID AND LocationName = @LocationName ',10)"; SqlCommand Cmd = new SqlCommand(SQLText, SqlConnection); Cmd.Parameters.Add("@ClientID", SqlDbType.Int).Value = 7; // Insert real ClientID Cmd.Parameters.Add("@LocationName", SqlDbType.NVarChar(20)).Value = "Default"; // Real code uses Location Name from user input SqlDataReader reader = Cmd.ExecuteReader(); When I do this, I get the following code from SQL profiler: exec sp_executesql N'SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationID nvarchar(20)', @ClientID=7,@LocationName=N'Default' When this executes, SQL throws an error that it cannot parse past the first mention of @ClientID stating that the Scalar Variable @ClientID must be defined. If I modify the code to declare the variables first (see below), then I receive an error at the second mention of @ClientID that the variable already exists. exec sp_executesql N'DECLARE @ClientID int; DECLARE @LocationName nvarchar(20); SELECT Field1, COUNT(*) as RecordCount FROM GetDecileTable (''WHERE ClientID = @ClientID AND LocationName = @LocationName '',10)', N'@ClientID int,@LocationName nvarchar(20)', @ClientID=7,@LocationName=N'Default' I know that this method of adding parameters and calling SQL code from C# works well when I am selecting data from tables, but I am not sure how to embed parameters inside of the ' quote marks for the embedded WHERE clause being passed to the function. Any ideas?

  • Javascript/Greasemonkey: search for something then set result as a value

    - by thewinchester
    Ok, I'm a bit of a n00b when it comes to JS (I'm not the greatest programmer) so please be gentle - specially if my questions been asked already somewhere and I'm too stupid to find the right answer. Self deprecation out of the way, let's get to the question. Problem There is a site me and a large group of friends frequently use which doesn't display all the information we may like to know - in this case an airline bookings site and the class of travel. While the information is buried in the code of the page, it isn't displayed anywhere to the user. Using a Greasemonkey script, I'd like to liberate this piece of information and display it in a suitable format. Here's the psuedocode of what I'm looking to do. Search dom for specified element define variables Find a string of text If found Set result to a variable Write contents to page at a specific location (before a specified div) If not found Do nothing I think I've achieved most of it so far, except for the key bits of: Searching for the string: The page needs to search for the following piece of text in the page HEAD: mileageRequest += "&CLASSES=S,S-S,S-S"; The Content I need to extract and store is between the second equals (=) sign and the last comma ("). The contents of this area can be any letter between A-Z. I'm not fussed about splitting it up into an array so I could use the elements individually at this stage. Writing the result to a location: Taking that found piece of text and writing it to another location. Code so far This is what I've come up so far, with bits missing highlighted. buttons = document.getElementById('buttons'); ''Search goes here var flightClasses = document.createElement("div"); flightClasses.innerHTML = '<div id="flightClasses"> ' + '<h2>Travel classes</h2>' + 'For the above segments, your flight classes are as follows:' + 'write result here' + '</div>'; main.parentNode.insertBefore(flightClasses, buttons); If anyone could help me, or point me in the right direction to finish this off I'd appreciate it.

  • How can i handle a form submit using REAL OOP in PHP

    - by Lorence
    Im used to java and creating UML.. and i was wondering how can PHP be OOP, the objects live only until you make a request.. then they destroy, so if im using a database is useless to create a class and add the members (variables) to the class, they will be useless.. i cant pass the main system object from one page to another, or similar so how can PHP be compare to jave? you never do OOP .. i mean REAL OOP.. not creating classes , in fact your index will be a procedural file with some object instance and then ? how about if i make a html form and i want to submit the data.. i have to call a file which is not a class is a php procedural file were i grab the submited data with POST, from that file you will instance a class and do some logic there.. but for me thats not pure OOP.. can somebody point me to the right way of OOP using a form submit example ? Thanks!

  • How do I resolve no swt-cocoa-3557 or swt-cocoa in swt.library.path, java.library.path or the jar fi

    - by ?????
    I can't get a swt application to work on Mac OSX Snow Leopard. Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-cocoa-3557 or swt-cocoa in swt.library.path, java.library.path or the jar file at org.eclipse.swt.internal.Library.loadLibrary(Unknown Source) at org.eclipse.swt.internal.Library.loadLibrary(Unknown Source) at org.eclipse.swt.internal.C.<clinit>(Unknown Source) at org.eclipse.swt.internal.cocoa.NSThread.isMainThread(Unknown Source) at org.eclipse.swt.graphics.Device.<init>(Unknown Source) at org.eclipse.swt.widgets.Display.<init>(Unknown Source) at org.eclipse.swt.widgets.Display.<init>(Unknown Source) at com.astrobetty.geotag.Hello.main(Hello.java:12) I have added -Dswt.library.path= and -Djava.library.path statements to the "VM arrguments" hand have also tried setting them as variables in the "environment" section of the Eclipse run configuration page. I've verified that my .jar file is at the path I specify. If I look inside the .jar, it seems to contain these libraries: 102 Feb 12 13:21 META-INF 183 Feb 12 13:21 external.xpt 37104 Nov 17 2009 libswt-awt-cocoa-3557.jnilib 287228 Nov 17 2009 libswt-cocoa-3557.jnilib 548252 Nov 17 2009 libswt-pi-cocoa-3557.jnilib 313420 Nov 17 2009 libswt-xulrunner-cocoa-3557.jnilib 136 May 23 22:19 org 13 Feb 12 13:21 version.txt Any ideas on how to get this to work? Is it possible at all?

  • Android's RelativeLayout Unit Test setup

    - by dqminh
    i'm trying to write an unit test for my Android's RelativeLayout. Currently, my testcode setup is as follow: public class SampleRelativeLayoutTest extends AndroidTestCase { private ViewGroup testView; private ImageView icon; private TextView title; @Override protected void setUp() throws Exception { super.setUp(); // inflate the layout final Context context = getContext(); final LayoutInflater inflater = LayoutInflater.from(context); testView = (ViewGroup) inflater.inflate(R.layout.sample_layout, null); // manually measure and layout testView.measure(500, 500); testView.layout(0, 0, 500, 500); // init variables icon = (ImageView) testView.findViewById(R.id.icon); title = (TextView) testView.findViewById(R.id.title); } However, I encountered NullPointerException with the following stack trace java.lang.NullPointerException at android.widget.RelativeLayout.onMeasure(RelativeLayout.java:427) at android.view.View.measure(View.java:7964) at com.dqminh.test.view.SampleRelativeLayoutTest.setUp(SampleRelativeLayoutTest.java:33) at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:169) at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:154) at android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:430) at android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447) What should I change in my setUp() code to make the test run properly ?

  • Java: How to have an ArrayList as instance variable of an object?

    - by JDelage
    All, I'm working on a class project to build a little Connect4 game in Java. My current thinking is to have a class of Columns that have as instance variable a few integers (index, max. length, isFull?) and one ArrayList to receive both the integers above and the plays of each players (e.g., 1's and 0's standing for X's and O's). This is probably going to be split between 2 classes but the question remains the same. My current attempt looks like this: import java.util.ArrayList; public class Conn4Col { public int hMax; public int index; public final int initialSize = 0; public final int fullCol = 0; public ArrayList<Integer>; (...)} Unfortunately, this doesn't compile. The compiler says an is missing where my ArrayList declaration stands. We're just starting objects and we haven't really looked into other instance variables than the basic types. Can someone tell me where my error is and how to correct it? Many thanks, JDelage

  • Pre Commit Hook for JSLint in Mercurial and Git

    - by jrburke
    I want to run JSLint before a commit into either a Mercurial or Git repo is done. I want this as an automatic step that is set up instead of relying on the developer (mainly me) remembering to run JSLint before-hand. I normally run JSLint while developing, but want to specify a contract on JS files that they pass JSLint before being committed to the repo. For Mercurial, this page spells out the precommit syntax, but the only variables that seem to be available are the parent1 and parent2 changeset IDs involved in the commit. What I really want are a list of file names that are involved with the commit, so that I can then choose the .js file and run jslint over them. Similar issue for GIT, the default info available as part of the precommit script seems limited. What might work is calling hg status/git status as part of the precommit script, parse that output to find JS files then do the work that way. I was hoping for something easier though, and I am not sure if calling status as part of a precommit hook reflect the correct information. For instance in Git if the changes files have not been added yet, but the git commit uses -a, would the files show up in the correct section of the git status output as being part of the commit set? Update: I got something working, it is visible here: http://github.com/jrburke/dvcs_jslint/

  • iPad: Move UIView with animation, then move it back

    - by Joel
    I have the following code in a UIView subclass that will move it off the screen with an animation: float currentX = xposition; //variables that store where the UIView is located float currentY = yposition; float targetX = -5.0f - self.width; float targetY = -5.0f - self.height; moveX = targetX - currentX; //stored as an instance variable so I can hang on to it and move it back moveY = targetY - currentY; [UIView beginAnimations:@"UIBase Hide" context:nil]; [UIView setAnimationDuration:duration]; self.transform = CGAffineTransformMakeTranslation(moveX,moveY); [UIView commitAnimations]; It works just great. I've changed targetX/Y to 0 to see if it does indeed move to the specified point, and it does. The problem is when I try and move the view back to where it was originally: moveX = -moveX; moveY = -moveY; [UIView beginAnimations:@"UIBase Show" context:nil]; [UIView setAnimationDuration:duration]; self.transform = CGAffineTransformMakeTranslation(moveX,moveY); [UIView commitAnimations]; This puts the UIView about 3x as far as it should. So the view usually gets put off the right side of the screen (depending on where it is). Is there something with the CGAffineTransforMakeTranslation function that I should know? I read the documentation, and from what I can tell, it should be doing what I'm expecting it to do. Anyone have a suggestion of how to fix this? Thanks.

  • WPF - Dynamic tooltip

    - by Al Mackenzie
    I have a class ToolTipProvider which has a method string GetToolTip(UIElement element) which will return a specific tooltip for the UIElement specified, based on various factors including properties of the UIElement itself and also looking up into documentation which can be changed dynamically. It will also probably run in a thread so when the form first fires up the tooltips will be something like the visual studio 'Document cache is still being constructed', then populated in the background. I want to allow this to be used in any wpf form with the minimum effort for the developer. Essentially I want to insert an ObjectDataProvider resource into the Window.Resources to wrap my ToolTipProvider object, then I think I need to create a tooltip (called e.g. MyToolTipProvider) in the resources which references that ObjectDataProvider, then on any element which requires this tooltip functionality it would just be a case of ToolTip="{StaticResource MyToolTipProvider}" however I can't work out a) how to bind the actual elemnt itself to the MethodParameters of the objectdataprovider, or b) how to force it to call the method each time the tooltip is opened. Any ideas/pointers on the general pattern I need? Not looking for complete solution, just any ideas from those more experienced

  • Silverlight 4, combobox databinding problem

    - by synergetic
    In my Silverlight 4 app, CustomerView (UserControl) shows Customer object as it's DataContext. Customer object has IndustryCode string property. I created combobox called cboIndustryCode and bind it to the IndustryCode property the following way: <ComboBox x:Name="cboIndustryCode" SelectedValue="{Binding IndustryCode, Mode=TwoWay}" ... /> In code-behind I populate cboIndustryCode with List of Industry object, which has Code and Name properties: cboIndustryCode.ItemsSource = industries; //which is of List<Industry> type Now, to show everything properly, in XAML I added the following: <ComboBox x:Name="cboIndustryCode" SelectedValue="{Binding IndustryCode, Mode=TwoWay}" DisplayMemberPath="Name" SelectedValuePath="Code" ... /> So, when I get a customer class from my data layer and set the DataContext to this customer instance, the cboIndustryCode properly displays industry name. But, then I edit customer (not necessarily IndustryCode) and save the object (which resets DataContext = new Customer()) and retrieve the customer again from database, and I see that cboIndustryCode no longer working. It just displays nothing, and if I select new value from the list, it does not update underlying customer object's IndustryCode property. The problem goes away, if I put the following code in the place where I set DataContext to a instance of customer, retrieved from database: Binding binding = new Binding("IndustryCode"); binding.Mode = BindingMode.TwoWay; cboIndustryCode.SetBinding(ComboBox.SelectedValueProperty, binding); So, in short, combobox's binding is reset somehow every time I save my data. Can someone tell me the reason?
