  • Flex AS3: Assign a button's upSkin property with a remote file dynamically?

    - by Aaron
    I am building a Flex application with ActionScript 3. Unfortunately I've hit a wall with this one... I would like to be able to apply an upSkin to my dynamically generated button like this: //this theSkin variable is dynamic in my app, but for this example it's a simple string var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif"; var navBtn:Button = new Button(); navBtn.id = "thumb1"; navBtn.width = 60; navBtn.height = 45; //skin the button navBtn.setStyle("upSkin", theSkin); //add the button to my canvas myCanvas.addChild(navBtn); When I attempt this, I get this error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class. How do I skin this button with my image dynamically? A couple of things to consider: The upSkin image must be remote. It can't be local. The button must be generated dynamically (it's in a for loop). Any help/ideas would be much appreciated at this point!

  • Displaying Many-To-Many Database relationship in VB.NET 2008 with DataGrid, MS SQL 2008

    - by user337501
    Computer bombed while posting this, couldnt find a duplicate question but if there is one, forgive me. So, I've run into a wall. And rather than use a ladder to avoid it, I'd like go through it. I'm setting up what I can best describe as a many-to-many relationship in a database. To examplify, imagine I have three primary tables: Items, Categories, Sections(nevermind the potential redundancy) Then I have another table, Properties. Items, Categories, and Sections can be associated with many properties. A single property can be associated with one, all, or none of the other tables. The best way I can figure to do this is to have join tables make the relationship. i.e. tblItems----(Foreign Key)----tblItems_To_Properties----(Foreign Key)----tblProperties In this example, tblItems simply has an "ItemID" Primary Key. tblItems_To_Properties has its own Primary Key(tblItems_To_PropertiesID), a Foreign Key to the Item(ItemID) and a Foreign key to the Property(PropertyID). The Properties table simply has its primary key(PropertyID) I hope this example isnt too confusing...if I have to I can find a way to put a diagram up or something. My problem is, I want to display this in a DataGrid using the Master-Detail method(DevExpress GridControl). I use the tblItems as a test, and I can see the Items in the parent view, but in the child view I see(understandably) the join table and that is it. My goal is to make it so the Grid ignores the join table and shows the Properties table as the only child. Any help on this method or insight into another solution would be muuuuuuuch appreciat

  • Facebook JS API: How to get FB.Connect.streamPublish to use auto_publish

    - by Prody
    I'm trying to publish stuff to someone's wall. It works, but I'm also trying to use the auto_publish feature so the user will only get one popup granting the publish_stream extended permission. So I set streamPublish's auto_publish to true, but I still get the popup asking me if I want to publish and/or edit the message. What am I doing wrong? Here's what I'm running: FB.ensureInit(function () { FB.Facebook.get_sessionState().waitUntilReady(function() { FB.Connect.showPermissionDialog("publish_stream", function(perms) { if (perms == "publish_stream") { FB.Facebook.apiClient.friends_get(null, function(result) { var markup = ""; var targets = result; targets = [testFriendsIDForTesting]; var attachment = { name: "Blablabla", href: window.location.href, description: "description", caption: "caption" }; var actionLinks = [{ text: "View", href: window.location.href }]; var num_targets = targets.length; for (var i=0; i<num_targets; i++) { var fId = targets[i]; FB.Connect.streamPublish("none", attachment, actionLinks, fId, "none", null, false); } }); } }); }); });

  • Image "moves" when varying heightForRowAtIndexPath in UITableViewCell.

    - by Kalle
    I have a table view with varying height, as defined in the heightForRowAtIndexPath. For some very odd reason, the image is "indented" to the right based on the height; if the height is low enough, the image is stuck to the left side of the cell, but as the height increases, the image for said cell is shifted rightward compared to other rows. The result of this is a very poor looking list, with images floppily laid out in a zig-zag pattern depending on the height of each individual row. The problem is revealed by this simple example: - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return (indexPath.row+1) * 50; } Each cell is set up (simplified) as a "Subtitle" style cell with: // ... cell.textLabel.text = @"foo"; cell.detailTextLabel.text = @"bar"; cell.imageView.backgroundColor = [UIColor redColor]; // for debugging; i have images with transparent bg cell.imageView.image = anImageThatIs55x50pixelsBig; return cell; Any ideas? My head bleeds from the wall-love-affair. Edit: uploaded a screen which displays this. The "image" is just a screenshot of a tiny area of the screen which makes it look a little weird, but you get the picture I'm sure: http://img28.imageshack.us/img28/549/screenshot20100311at172.png

  • Help matching fields between two classes

    - by Michael
    I'm not too experienced with Java yet, and I'm hoping someone can steer me in the right direction because right now I feel like I'm just beating my head against a wall... The first class is called MeasuredParams, and it's got 40+ numeric fields (height, weight, waistSize, wristSize - some int, but mostly double). The second class is a statistical classifier called Classifier. It's been trained on a subset of the MeasuredParams fields. The names of the fields that the Classifier has been trained on is stored, in order, in an array called reqdFields. What I need to do is load a new array, toClassify, with the values stored in the fields from MeasuredParams that match the field list (including order) found in reqdFields. I can make any changes necessary to the MeasuredParams class, but I'm stuck with Classifier as it is. My brute-force approach was to get rid of the fields in MeasuredParams and use an arrayList instead, and store the field names in an Enum object to act as an index pointer. Then loop through the reqdFields list, one element at a time, and find the matching name in the Enum object to find the correct position in the arrayList. Load the value stored at that positon into toClassify, and then continue on to the next element in reqdFields. I'm not sure how exactly I would search through the Enum object - it would be a lot easier if the field names were stored in a second arrayList. But then the index positions between the two would have to stay matched, and I'm back to using an Enum. I think. I've been running around in circles all afternoon, and I keep thinking there must be an easier way of doing it. I'm just stuck right now and can't see past what I've started. Any help would be GREATLY appreciated. Thanks so much! Michael

  • Synchronize DataGrid and DataForm in Silverlight 3

    - by SpiralGray
    I've been banging my head against the wall for a couple of days on this and it's time to ask for help. I've got a DataGrid and DataForm on the same UserControl. I'm using an MVVM approach so there is a single ViewModel for the UserControl. That ViewModel has a couple of properties that are relevant to this discussion: public ObservableCollection<VehicleViewModel> Vehicles { get; private set; } public VehicleViewModel SelectedVehicle { get { return selectedVehicle; } private set { selectedVehicle = value; OnPropertyChanged( "SelectedVehicle" ); } } In the XAML I've got the DataGrid and DataForm defined as follows: <data:DataGrid SelectionMode="Single" ItemsSource="{Binding Vehicles}" SelectedItem="{Binding SelectedVehicle, Mode=TwoWay}" AutoGenerateColumns="False" IsReadOnly="True"> <dataFormToolkit:DataForm CurrentItem="{Binding SelectedVehicle}" /> So as the SelectedItem changes on the DataGrid it should push that change back to the ViewModel and when the ViewModel raises the OnPropertyChanged the DataForm should refresh itself with the information for the newly-selected VehicleViewModel. However, the setter for SelectedVehicle is never being called and in the Output window of VS I'm seeing the following error: System.Windows.Data Error: ConvertBack cannot convert value 'xxxx.ViewModel.VehicleViewModel' (type 'xxxx.ViewModel.VehicleViewModel'). BindingExpression: Path='SelectedVehicle' DataItem='xxxx.ViewModel.MainViewModel' (HashCode=31664161); target element is 'System.Windows.Controls.DataGrid' (Name=''); target property is 'SelectedItem' (type 'System.Object').. System.MethodAccessException: xxxx.ViewModel.MainViewModel.set_SelectedVehicle(xxxx.ViewModel.VehicleViewModel) It sounds like it's having a problem converting from a VehicleViewModel to an object (or back again), but I'm confused as to why that would be (or even if I'm on the right track with that assumption). Each row/item in the DataGrid should be a VehicleViewModel (because the ItemsSource is bound to an ObservableCollection of that type), so when the SelectedItem changes it should be dealing with an instance of VehicleViewModel. Any insight would be appreciated.

  • Bad linking in Qt unit test -- missing the link to the moc file?

    - by dwj
    I'm trying to unit test a class that inherits QObject; the class itself is located up one level in my directory structure. When I build the unit test I get the standard unresolved errors if a class' MOC file cannot be found: test.obj : error LNK2001: unresolved external symbol "public: virtual void * __thiscall UnitToTest::qt_metacast(char const *)" (?qt_metacast@UnitToTest@@UAEPAXPBD@Z) + 2 missing functions The MOC file is created but appears to not be linking. I've been poking around SO, the web, and Qt's docs for quite a while and have hit a wall. How do I get the unit test to include the MOC file in the link? ==== My project file is dead simple: TEMPLATE = app TARGET = test DESTDIR = . CONFIG += qtestlib INCLUDEPATH += . .. DEPENDPATH += . HEADERS += test.h SOURCES += test.cpp ../UnitToTest.cpp stubs.cpp DEFINES += UNIT_TEST My directory structure and files: C:. | UnitToTest.cpp | UnitToTest.h | \---test | test.cpp (Makefiles removed for clarity) | test.h | test.pro | stubs.cpp | +---debug | UnitToTest.obj | test.obj | test.pdb | moc_test.cpp | moc_test.obj | stubs.obj Edit: Additional information The generated Makefile.Debug shows the moc file missing: SOURCES = test.cpp \ ..\test.cpp \ stubs.cpp debug\moc_test.cpp OBJECTS = debug\test.obj \ debug\UnitToTest.obj \ debug\stubs.obj \ debug\moc_test.obj

  • form with multiple upload but allow no upload on edit problems

    - by minus4
    hiya i have a section that when created takes in images, however when you edit this item i dont want them to re-upload none changes images just to change a description or name. i have created this that deals with uploading files: public void UploadFiles(string currentFileName, FormCollection form) { // loop through all files in form post foreach (string file in Request.Files) { HttpPostedFileBase hpf = Request.Files[file]; // if no file is uploaded, we could be editing so set to current value if (hpf.ContentLength == 0) { form[file] = currentFileName; } else { //rename the file unique so we dont clash with names var filename = hpf.FileName.Replace(" ", "_").Replace(".", DateTime.Now.Date.Ticks + "."); UploadFileName = filename; hpf.SaveAs(Server.MapPath("~/Content/custom/" + filename)); // set the name of the file in our post to the new name form[file] = UploadFileName; } } // ensure value is still sent when no files are uploaded on edit if(Request.Files.Count <= 0) { UploadFileName = currentFileName; } } all works fine when only one image is required (CurrentFileName), however there is now a new image available taking it to a total of 2 images in the database therefor currentFileName is obsolete. has anyone tackled this and how as i have hit a wall with this one. thought of string[] currentFiles but cant see how to match this into string file in Request.Files. if it helps i am also working with models for the form so i could pass over the model but i dont think your able to do model.file without some kind of reflection. help much appreciated. thanks

  • How do I make Views fill the full width of their parent in my Android app?

    - by Omega
    I have the following layout defined for one of my Activities: <?xml version="1.0" encoding="utf-8"?> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <TableRow android:id="@+id/TableRow01" android:layout_height="wrap_content" android:layout_width="fill_parent"> <EditText android:text="Resource Name" android:id="@+id/ResourceName" android:lines="1" android:isScrollContainer="false"></EditText> </TableRow> <TableRow android:id="@+id/TableRow02" android:layout_height="wrap_content" android:layout_width="fill_parent"> <Button android:id="@+id/Tile" android:text="Tile"></Button> </TableRow> </TableLayout> The layout renders almost correctly, the only problem is that my text box and my button aren't occupying the full width of their respective rows. I've tried specifying fill_parent for the layout width properties, but to no avail, they still only occupy roughly half of the screen. Documentation overall for Android so far has been great, but there are a few scenarios like this one where I hit an invisible wall! Thanks for all the help!

  • SpeechSynthesizer Exception - Please Help

    - by Chris
    Hi. I have the following code: private List<VoiceInfo> GetInstalledVoices(SpeechSynthesizer synthesizer) { CultureInfo currentCulture = CultureInfo.CurrentCulture; var listOfVoiceInfo = from voice in synthesizer.GetInstalledVoices(currentCulture) select voice.VoiceInfo; return listOfVoiceInfo.ToList<VoiceInfo>(); } I then call the code from the following code snippet: var synthesizer = new SpeechSynthesizer(); var installedVoices = GetInstalledVoices(synthesizer); VoiceInfo voice = null; if (installedVoices != null && installedVoices.Count > 0) { voice = installedVoices.FirstOrDefault(); } if (voice != null) { synthesizer.SelectVoice(voice.Name); } The line of code that selects the voice throws the following exception: "Cannot set voice. No matching voice is installed or the voice was disabled." This is being done from within an ASP.NET web application - running on Windows Server 2003 R2. When I run this from within Visual Studio 2008 - everything works fine. I created a simple Console app to perform the same action - then ran it from the Windows Server 2003 machine - and it worked fine. I even modified the code in the Console app to loop through each of the installed voices and select the voice. No problems. However, when doing the same from within the web application, I get the same error. I am beating my head against a wall on this one. ANY help on this would be greatly appreciated. Thanks. Chris

  • Virtual Lan on the Cloud -- Help Confirm my understanding?

    - by marfarma
    [Note: Tried to post this over at ServerFault, but I don't have enough 'points' for more than one link. Powers that be, move this question over there.] Please give this a quick read and let me know if I'm missing something before I start trying to make this work. I'm not a systems admin professional, and I'd hate to end up banging my head into the wall if I can avoid it. Goals: Create a 'road-warrior' capable star shaped virtual LAN for consultants who spend the majority of their time on client sites, and who's firm has no physical network or servers. Enable CIFS access to a cloud-server based installation of Alfresco Allow Eventual implementation of some form of single-sign-on ( OpenLDAP server ) access to Alfresco and other server applications implemented in the future Given: All Servers will live in the public internet cloud (Rackspace Cloud Servers) OpenVPN Server will be a Linux disto, probably Ubuntu 9.x, installed on same server as Alfresco (at least to start) Staff will access server applications and resources from client sites, hotels, trains, planes, coffee shops or their homes over various ISP, using their company laptops or personal home desktops. Based on my Research thus far, to accomplish this, I'll need: OpenVPN with Bridging Enabled to create a star shaped "virtual" LAN http://openvpn.net/index.php/open-source/documentation/miscellaneous/76-ethernet-bridging.html A Road Warrior Network Configuration, as described in this Shorewall article (lower down the page) http://www.shorewall.net/OPENVPN.html Configure bridge addressesing (probably DHCP) http://openvpn.net/index.php/open-source/faq.html#bridge-addressing Configure CIFS / Samba to accept VPN IP address http://serverfault.com/questions/137933/howto-access-samba-share-over-vpn-tunnel Set up Client software, with keys configured for access (potentially through a OpenVPN-Sa client portal) http://www.openvpn.net/index.php/access-server/download-openvpn-as/221-installation-overview.html

  • Keyboard hook return different symbols from card reader depends whther my app in focus or not

    - by user363868
    I code WinForm application where one of the input is magnetic stripe card reader (CR). I am using code George Mamaladze's article Processing Global Mouse and Keyboard Hooks in C# on codeproject.com to listen keyboard (USB card reader acts same way as keyboard) and I have weird situation. One card reader CR1 (Unitech MS240-2UG) produces keystroke which I intercept on KeyPress event analyze that I intercept certain patter like %ABCD-6EFJHI? and trigger some logic. Analysis required because user can type something else into application or in another application meanwhile my app is open When I use another card reader CR2 (IdTech IDBM-334133) keystroke intercepted by hook started from number 5 instead of % (It is actually same key on keyboard). Since it is starting sentinel it is very important for me to have ability recognize input from card reader. Moreover if my app running in background and I have focus on Notepad when I swipe card string %ABCD-6EFJHI? appears in Notepad and same way, with proper starting character) intercepted by keyboard hook. If swiped when focus on Form it is 5ABCD-6EFJHI? User who tried app with another card reader has same result as me with CR2. Only CR1 works for me as expected I was looking into Device manager of Windows and both devices use same HID driver supplied by MS. I checked devices though respective software from CR makers and starting and ending sentinels set to % and ? respective on both. I would appreciate and ideas and thoughts as I hit the wall myself Thank you

  • Rails: Multiple "has_many through" for the two same models?

    - by neezer
    Can't wrap my head around this... class User < ActiveRecord::Base has_many :fantasies, :through => :fantasizings has_many :fantasizings, :dependent => :destroy end class Fantasy < ActiveRecord::Base has_many :users, :through => :fantasizings has_many :fantasizings, :dependent => :destroy end class Fantasizing < ActiveRecord::Base belongs_to :user belongs_to :fantasy end ... which works fine for my primary relationship, in that a User can have many Fantasies, and that a Fantasy can belong to many Users. However, I need to add another relationship for liking (as in, a User "likes" a Fantasy rather than "has" it... think of Facebook and how you can "like" a wall-post, even though it doesn't "belong" to you... in fact, the Facebook example is almost exactly what I'm aiming for). I gathered that I should make another association, but I'm kinda confused as to how I might use it, or if this is even the right approach. I started by adding the following: class Fantasy < ActiveRecord::Base ... has_many :users, :through => :approvals has_many :approvals, :dependent => :destroy end class User < ActiveRecord::Base ... has_many :fantasies, :through => :approvals has_many :approvals, :dependent => :destroy end class Approval < ActiveRecord::Base belongs_to :user belongs_to :fantasy end ... but how do I create the association through Approval rather than through Fantasizing? If someone could set me straight on this, I'd be much obliged!

  • DataBinding the AJAX Control Toolkit's Rating Control

  • Making a 64 bit shared library that dynamically links to a 32 bit library on Mac OS X Snow Leopard

    - by carneades
    Update: After some more reading I see that this problem is totally general, you can't mix architectures in the same process, so 64 bit Java cannot dlopen() a 32 bit library like FMOD. Is there any possible workaround for this, keeping in mind I'm writing my own C interface to the FMOD library? I need to make a 64-bit dylib on Max OS X because Java Native Access only likes 64-bit libraries on 64-bit machines. The problem is, my C source code dynamically includes FMOD which on Mac only provides 32-bit dylibs. When I try to compile without the -m32 option (since I must output a 64-bit dylib) I get the following error: gcc -dynamiclib -std=c99 -pedantic -Wall -O3 -fPIC -pthread -o ../bin/libpenntotalrecall_fmod.dylib ../../src/libpenntotalrecall_fmod.c -lfmodex -L../../lib/osx/ ld: warning: in /usr/lib/libfmodex.dylib, missing required architecture x86_64 in file Undefined symbols: "_FMOD_System_CreateSound", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_Channel_GetPosition", referenced from: _streamPosition in ccJnlwrd.o "_FMOD_System_Create", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_System_PlaySound", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_Sound_Release", referenced from: _stopPlayback in ccJnlwrd.o "_FMOD_Channel_IsPlaying", referenced from: _playbackInProgress in ccJnlwrd.o "_FMOD_System_Update", referenced from: _streamPosition in ccJnlwrd.o _startPlayback in ccJnlwrd.o "_FMOD_Channel_SetPaused", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_System_Release", referenced from: _stopPlayback in ccJnlwrd.o "_FMOD_System_Init", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_Channel_SetVolume", referenced from: _startPlayback in ccJnlwrd.o "_FMOD_System_Close", referenced from: _stopPlayback in ccJnlwrd.o "_FMOD_Channel_SetCallback", referenced from: _startPlayback in ccJnlwrd.o ld: symbol(s) not found collect2: ld returned 1 exit status make: *** [all] Error 1 Shouldn't it be possible to get a 64 bit dylib from my source code that dynamically includes 32 bit libraries?!

  • Catching a nested-in-template exception [C++]

    - by Karol
    Hello, I have a problem with writing a catch clause for an exception that is a class nested in a template. To be more specific, I have a following definition of the template and exception: /** Generic stack implementation. Accepts std::list, std::deque and std::vector as inner container. */ template < typename T, template < typename Element, typename = std::allocator<Element> > class Container = std::deque > class stack { public: class StackEmptyException { }; ... /** Returns value from the top of the stack. Throws StackEmptyException when the stack is empty. */ T top() const; ... } I have a following template method that I want exception to catch: template <typename Stack> void testTopThrowsStackEmptyExceptionOnEmptyStack() { Stack stack; std::cout << "Testing top throws StackEmptyException on empty stack..."; try { stack.top(); } catch (Stack::StackEmptyException) { // as expected. } std::cout << "success." << std::endl; } When I compile it (-Wall, -pedantic) I get the following error: In function ‘void testTopThrowsStackEmptyExceptionOnEmptyStack()’: error: expected type-specifier error: expected unqualified-id before ‘)’ token === Build finished: 2 errors, 0 warnings === Thanks in advance for any help! What is interesting, if the stack implementation was not a template, then the compiler would accept the code as it is.

  • Building a News-feed that comprises posts "created by user's connections" && "on the topics user is following"

    - by aklin81
    I am working on a project of Questions & Answers website that allows a user to follow questions on certain topics from his network. A user's news-feed wall comprises of only those questions that have been posted by his connections and tagged on the topics that he is following(his expertise topics). I am confused what database's datamodel would be most fitting for such an application. The project needs to consider the future provisions for scalability and high performance issues. I have been looking at Cassandra and MySQL solutions as of now. After my study of Cassandra I realized that Simple news-feed design that shows all the posts from network would be easy to design using Cassandra by executing fast writes to all followers of a user about the post from user. But for my kind of application where there is an additional filter of 'followed topics', (ie, the user receives posts "created by his network" && "on topics user is following"), I could not convince myself with a good schema design in Cassandra. I hope if I missed something because of my short understanding of cassandra, perhaps, can you please help me out with your suggestions of how this news-feed could be implemented in Cassandra ? Looking for a great project with Cassandra ! Edit: There are going to be maximum 5 tags allowed for tagging the question (ie, max 5 topics can be tagged on a question).

  • Iphone: TabView + TableView

    - by OneTrickPonySoft
    I think I'm missing something simple, but I can't figure out exactly what it is. I'm trying to set up an App with a UITabViewController, and one of the Tabs will have a UITableView and UISearchBar (but no Navigation Controller). I set up the UITabViewController with all the tabs in interface builder, and the views are in their own xib files. The xib file for the tab with the UITableView is set up and connected as follows. Stuff in the browser: File's owner (Class is my custom class that is a child of UITableViewController) view - View View (class UIView, reference view - File's owner) contains: UITableView (if i try and set references to the data source / delegate, the app breaks) UISearchBar (unconfigured at the moment) This setup displays all the items and doesn't lock up, but I can't assign a DataSource without it crashing when i try and load the tab with the UITableView. What should I do to get data into this table, either in IB or code? My ideas are as follows: Implement custom UITableView class, hook up to table view in IB or to custom tableviewcontroller in Xcode. Pound head or laptop against the wall until it works. Update: Here's the error the simulator pushes to the console when I connect the Tableview's data source and delegate to File Owner (who's class is my custom tableviewcontroller). 2/14/09 6:59:12 PM TabBarWillbeRight[33172] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x523760'
