  • Interface Design Problem: Storing Result of Transactions

    - by jboyd
    Requirements: multiple sources of input (social media content) into a system multiple destinations of output (social media api's) sources and destinations WILL be added some pseudo: IContentProvider contentProvider = context.getBean("contentProvider"); List<Content> toPost = contentProvider.getContent(); for (Content c : toPost) { SocialMediaPresence smPresence = socialMediaService.getSMPresenceBySomeId(c.getDestId()); smPresence.hasTwitter(); smPresence.hasFacebook(); //just to show what this is smPresence.postContent(c); //post content could fail for some SM platforms, but shoulnd't be lost forever } So now I run out of steam, I need to know what content has been successfully posted, and if it hasn't gone too all platforms, or if another platform were added in the future that content needs to go out for it as well (therefore my content provider will need to not only know if content has gone out, but for what platforms). I'm not looking for code, although sample/pseudo is fine... I'm looking for an approach to this problem that I can implement

  • Binding Many-to-Many Core Data relationships in UI

    - by Kevin
    Basically my setup is this. I have a many-to-many relationship in Core Data where a student entity can have multiple courses, and a course entity can have multiple students. My problem is in trying to figure out how to bind this relationship to the UI in Interface Builder. I want to be able to add courses to a course array controller, then have those courses displayed in a popup menu in a NSTableView in the Edit Student window where you can add courses to a student. This is what I have so far: http://vimeo.com/10671726 It's probably easier to understand from the video. Thanks

  • NSString not applying to UILabel

    - by lyonjtill
    - (void)restoreUserDefaults { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; if([defaults objectForKey:@"Exam Name"] == nil) { examName = [[NSString alloc] initWithString:@"Name"]; } else { examName = [[NSString alloc] initWithString:[defaults objectForKey:@"Exam Name"]]; } [examNameLabel setText:examName]; NSLog(@"New Exam Schedule - Exam Name - %@",[defaults objectForKey:@"Exam Name"]); NSLog(@"examName = %@", examName); NSLog(@"examNameLabel = %@", examNameLabel); } Dear all, Basically above is a basic method to change a UILabel to a saved piece of data. I am having a problem making the label change to the NSString examName. I have checked Interface Builder and it's connected up. Any ideas why? Regards Lyon J Till

  • SD card initialization using SPI interface

    - by Tobias
    I get invalid response Codes from my SD Card(CMD8, CMD55, CMD41) Init routine: SDCS = 1; // MMC deaktiviert SPI1CON1bits.SMP = 0; SPI1CON1bits.CKE = 1; SPI1CON1bits.MSTEN = 1; SPI1CON1bits.CKP = 0; SPI1STATbits.SPIEN = 1; for(i=0;i<10;i++) SPI(0xFF); // RESET unsigned char rr=Command(CMD0,0); SDCS=1; // MMC deactivated /*OK response == 1*/ r=Command(CMD8,0); // check voltage SDCS=1; /* response == 0xC1 ?!? */ r = Command(CMD58,0); // READ_OCR unsigned char ocr1 = SPI(0xFF); unsigned char ocr2 = SPI(0xFF); unsigned char ocr3 = SPI(0xFF); unsigned char ocr4 = SPI(0xFF); unsigned char ocr5 = SPI(0xFF); /* r = 0xF8; ?!? ocr1 = 0x0F; ocr2 = 0xFF; ocr3 = 0xFF; ocr4 = 0xFF; ocr5 = 0xFF; */ SDCS=1; // INIT unsigned char rrr = 0; i=10000; do { rrr=Command(55,0); // Next is APP CMD SDCS=1; if(r) break; }while(--i>0); /* OK response == 1 */ // APP CMD 41 with OCR = 0x0F?? You can read the response codes in the comments. Is it possible the response code to CMD8 is 0xC1? Bit 7 should be 0, right? Is it a hardware error?

  • Office 2003 interop problems, interface, method not found.

    - by Snake
    This problem is making me crazy. Actually I have multiple problems. First one: Why on earth are is there a _Worksheet and a Worksheetinterface in the Excel interop. They both look the same, except for some attributes on the methods. It's confusing! Second of all: my job today is making a VB.NET file more strict, by settings Option Strict On and Option Explicit On While it works for most files, I'm bumping into a problem. Here's a little code piece: Private _pivotTable As Excel.PivotTable With _pivotTable pvf = .AddDataField(pvc) End With PivotTable.AddDataField is defined on the MSDN page: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.excel.pivottable.adddatafield(office.11).aspx When I check my local Interop dll w/ Reflector that method is NOT there. When I run the application, and step through it, the method just works. When I try to step INTO the method, I get an LateBound Exception. WTF? So the question is: why are the interfaces defined more than once (twice sometimes?). 2nd question. AddDataField trouble

  • Any way to trigger interface orientation check?

    - by Johnny Tee
    My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!

    Hello, I am writing a class. I have encountered the problem in the title. Here is the code: class delivery { private string strDeliveryName; private string strDeliveryAddress; private string strDeliveryDay; private string strDeliveryTime; private string strDeliveryMeal; private string strDeliveryInstructions; private string strDeliveryStatus; } public delivery(string deliveryName, string deliveryAddress, string deliveryDay, string deliveryTime, string deliveryMeal, string deliveryInstructions, string deliveryStatus) { strDeliveryName = deliveryName; strDeliveryAddress = deliveryAddress; strDeliveryDay = deliveryDay; strDeliveryTime = deliveryTime; strDeliveryMeal = deliveryMeal; strDeliveryInstructions = deliveryInstructions; strDeliveryStatus = deliveryStatus; } I get the error on the public delivery, any idea why?

  • Man machine interface command syntax and parsing

    - by idimba
    What I want is to add possibility to interact with application, and be able to extract information from application or event ask it to change some states. For that purpose I though of building cli utility. The utility will connect to the application and send user commands (one line strings) to the application and wait for response from the application. The command should contain: - command name (e.g. display-session-table/set-log-level etc.) - optionally command may have several arguments (e.g. log-level=10) The question to choose syntax and to learn parse it fast and correctly. I don't want to reinvent the whell, so maybe there's already an answer out there.

  • User Interface functionality modelling languages?

    - by naugtur
    I am looking for a UI functionality modelling language (UML-alike "thing", but for user interfaces) that is already accepted and maybe has its design patterns and handles the problem better than state or activity diagram. (If there is no such thing I'm planning to develop that BTW :)) This question came to mind as a result of a discovery that UML and its diagrams fails at describing complicated UI functionality with event-driven flow of execution (ie. javascript/jQuery big projects) EDIT: I've been thinking of using BPMN but It was not created for this purpose. EDIT2: See this community topic of mine - I decided to start developing said language.

  • Cocoa: Creating a Window with a Variable Number of Interface Elements

    - by Rui Pacheco
    Hi, I've a window that will have an unknown amount of text fields, determined by the content of a remote server. In high level terms, how should I go about this? Create a custom view or create an empty window with a backing NSWindowController and then add stuff to it when the window is opened? I've seen the examples on the O'Reilly Cocoa book and those effectively create a custom NSView. Is this the right way to do it, 8 year later?

  • Working examples of winform/WPF apps

    - by melody
    I'm a user interface designer. The project I'm working on is a dashboard that will have several interactive and customizable widgets (think Netvibes, etc.). The development group is going to be using either WinForm or WPF to build the dashboard and widgets. I need to understand the capabilities of each technology better and see a sampling of actual working apps to help accomplish this. I can't download and build examples... need live examples somewhere on the web. Can you point me to live, existing apps? Thx.

  • Flash External Interface issue with Firefox

    - by majestiq
    I am having a hard time getting ExternalInterface to work on Firefox. I am trying to call a AS3 function from javascript. The SWF is setup with the right callbacks and it is working in IE. I am using AC_RunActiveContent.js to embed the swf into my page. However, I have modified it to add an ID to the Object / Embed Tags. Below are object and embed tag that are generated for IE and for Firefox respectively. <object codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0" width="400" height="400" align="middle" id="jpeg_encoder2" name="jpeg_encoder3" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" > <param name="movie" value="/jpeg_encoder/jpeg_encoder3.swf" /> <param name="quality" value="high" /> <param name="play" value="true" /> <param name="loop" value="true" /> <param name="scale" value="showall" /> <param name="wmode" value="window" /> <param name="devicefont" value="false" /> <param name="bgcolor" value="#ffffff" /> <param name="menu" value="false" /> <param name="allowFullScreen" value="false" /> <param name="allowScriptAccess" value="always" /> </object> <embed width="400" height="400" src="/jpeg_encoder/jpeg_encoder3.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" align="middle" play="true" loop="true" scale="showall" wmode="window" devicefont="false" id="jpeg_encoder2" bgcolor="#ffffff" name="jpeg_encoder3" menu="false" allowFullScreen="false" allowScriptAccess="always" type="application/x-shockwave-flash" > </embed> I am calling the function like this... <script> try { document.getElementById('jpeg_encoder2').processImage(z); } catch (e) { alert(e.message); } </script> In Firefox, I get an error saying "document.getElementById("jpeg_encoder2").processImage is not a function" Any Ideas?

  • How to make a 3D UI for an application ?

    - by wacky_coder
    I'm building an application and I'd like its User Interface to be 3D, most probably a cylinder. The user would see the cylinder[Horizontally laid] and the cylinder's curved surface would have the buttons and any other controls that need to be placed. The cylinder needs to rotate and later, I'd like to add some other effects to the cylinder too. Someone told me that such a UI can be modelled using Maya or Blender and exported to openGL and then I could use C/C++ (with Qt) to carry out the actions. How can this be done?? Is there any other way to build the UI and do all the other things that I need ?? I really need some help because I have the UI in mind, but no idea on how to implement it. Thanks

  • UIVIewController wrong position before rotate

    - by zegnus
    I have the starter point of my application this window (white background): - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { mainScreen = [[MainScreenController alloc] initWithNibName:@"MainScreenController" bundle:[NSBundle mainBundle]]; // add it to the main window [window addSubview:[mainScreen view]]; // show view [window makeKeyAndVisible]; NSLog(@"started"); return YES; } And MainScreenController is an UIViewController with (blackBackground) created by the Interface Builder. The application executes perfectly but the first time, the black view is moved up like the height of the status iphone pannel (leaving white rectangle at the bottom). If I rotate the iPhone twice, the view is perfectly positioned in the right place, filling all the screen with the black background. Any idea? Thanks!

  • Presenting an image cropping interface

    - by wkw
    I'm trying to engineer a UI for cropping images in iphone OS and suspect I'm going about things the hard way. My goal is pretty much what the Tapbots duo have done with Pastebot. In that app, they dim the source image but provide a movable and resizable cropping view and the image you're cropping is in a zoomable scrollview; when you resize or move the underlying image, the cropping view adjusts appropriately. I mocked up a composite image which will give a sense of the design I'm after, along with how I presently have my view hierarchy setup, viewable here The approach I've started with is the following: UIImageView with the image to crop is in a scrollview, a plain UIView with black fill and suitable transparency/alpha setting is added in front of the imageview. I then use a custom UIView which is a sibling to the scrollview at a higher level, which implements the drawRect: method and for the most part calls CGImageCreateWithImageInRect to get the portion of the image's bitmap that matches the position of the cropping view and draws that to the CGContext. in the viewcontroller I'm using the UIScrollViewDelegate methods to track scrolling and passing those changes to the custom cropping UIView so it stays in sync with the scroll contentOffset. That much is finally working. But trying to keep in sync as the scrollview zoomScale changes is when I figured I should ask for help. Looking for suggestions or guidance. My initial approach just seems like more work than is required. Could this be done with a masking layer in the ImageView? And if so, how would I setup the tracking for moving and resizing the cropping rect? My experience working with layers is non-nil, but very limited thus far.

  • Using views as a data interface between modules in a database

    - by Stefan
    Hello, I am working on the database layout of a straighforward small database in Mysql. We want to modularize this system in order to have more flexiblity for different implementations we are going to make. Now, the idea was to have one module in the database (simple a group of tables with constraints between them) pass its data to the next module via views. In this way, changes in one module would not affect the other ones, as we can make sure in the view that the right data is present there at any time, although the underlying structure of tables might be different. The structure of the App handling the database would likewise be modularized. Is this something that is sometimes done? On a technical side, as I understand views can't have primary keys - how would I then adress such a view? What other issues should be considered?

  • UI Components for Windows Mobile Applications (.NET Compact Framework)

    - by splattne
    Applications which run on mobile devices have special user interface requirements. I think Apple did a great job introducing innovative controls on the iPhone/iPod touch platform. Now, I have to design an application for the Windows Mobile platform using the .NET Compact Framework (Visual Studio 2008). I wonder if there are some commercial or open source UI control sets available which are similar to the iPhone / iPod touch UI elements: Scrolling panels based on gestures Instead of a dropdownlist: a new panel with a large list of items Sliding panels etc. I couldn't find any useful products/code. Maybe there is somebody out there with more experience who could help.

  • std::ostream interface to an OLE IStream

    - by PaulH
    I have a Visual Studio 2008 C++ application using IStreams. I would like to use the IStream connection in a std::ostream. Something like this: IStream* stream = /*create valid IStream instance...*/; IStreamBuf< WIN32_FIND_DATA > sb( stream ); std::ostream os( &sb ); WIN32_FIND_DATA d = { 0 }; // send the structure along the IStream os << d; To accomplish this, I've implemented the following code: template< class _CharT, class _Traits > inline std::basic_ostream< _CharT, _Traits >& operator<<( std::basic_ostream< _CharT, _Traits >& os, const WIN32_FIND_DATA& i ) { const _CharT* c = reinterpret_cast< const _CharT* >( &i ); const _CharT* const end = c + sizeof( WIN32_FIND_DATA ) / sizeof( _CharT ); for( c; c < end; ++c ) os << *c; return os; } template< typename T > class IStreamBuf : public std::streambuf { public: IStreamBuf( IStream* stream ) : stream_( stream ) { setp( reinterpret_cast< char* >( &buffer_ ), reinterpret_cast< char* >( &buffer_ ) + sizeof( buffer_ ) ); }; virtual ~IStreamBuf() { sync(); }; protected: traits_type::int_type FlushBuffer() { int bytes = std::min< int >( pptr() - pbase(), sizeof( buffer_ ) ); DWORD written = 0; HRESULT hr = stream_->Write( &buffer_, bytes, &written ); if( FAILED( hr ) ) { return traits_type::eof(); } pbump( -bytes ); return bytes; }; virtual int sync() { if( FlushBuffer() == traits_type::eof() ) return -1; return 0; }; traits_type::int_type overflow( traits_type::int_type ch ) { if( FlushBuffer() == traits_type::eof() ) return traits_type::eof(); if( ch != traits_type::eof() ) { *pptr() = ch; pbump( 1 ); } return ch; }; private: /// data queued up to be sent T buffer_; /// output stream IStream* stream_; }; // class IStreamBuf Yes, the code compiles and seems to work, but I've not had the pleasure of implementing a std::streambuf before. So, I'd just like to know if it's correct and complete. Thanks, PaulH

  • Java: implementation of simple commands

    - by HH
    I have created a pkg for my regular simple commands. They are non-static, to be more extensible, but somewhat more time-consuming to use because of creating object to use one. My other classes use them. $ ls *.java CpF.java IsBinary.java RmLn.java Tools.java F2S.java IsRoot.java SaveToDisk.java WordCount.java Filters.java ModRelativePaths.java SetWord.java WordNumber.java Find.java powerTools.java Sort.java Which option would you choose to use them easier? to develop a small interface like 'powerTools.java' for the pkg. to create a class with static methods for them. to add a static method to each class to stop overusing 'creating too many files' and centralising some? sthing else?
