  • Problem in getting response from webserver

    - by Amarpreet
    Hi guys I am sending data to webserver in the Querystrings by creating URL dynamically. When I view that URl in UIAlertView it shows me correct one.

  • Android Internet permission and Google Play filtering

    - by Ivan
    I added <uses-permission android:name="android.permission.INTERNET" /> to my manifest in order to have access to Internet, but this is not a main function of my app. So, I don't want to get filtered in Google Play because of this. There is no matching <uses-feature> for this, so my question is what do I need to add with required="false" to avoid filtering. I guess I could add <uses-feature android:name="android.hardware.wifi" android:required="false" /> but what about mobile Internet (3G/4G), do I also need this? <uses-feature android:name="android.hardware.telephony" android:required="false"/> I want to know which filtering android.permission.INTERNET adds on Google Play, if it adds something.

  • Why shouldn't I use Flash?

    - by acidzombie24
    I heard many times i should avoid flash for my website. Yet no one has told me a good reason. I searched for reasons and i see many that are not true (such as text in flash are not indexable by search engines) or may not necessarily be true or significant enough (eating more bandwidth. Would a JS equivalent be bigger or smaller?). My site uses flash to playback sound (m4a). I dont have to worry about indexing, the back button not working, etc. But i have feeling there may be other reasons. What are reasons i shouldnt use flash on my website. I'll note one, the fact iphone/itouch and mobile devices does not support it. Not a big deal for most sites and is obvious. What are reason to avoid flash on my site?

  • iPhone UITableView populating variable rows sections from flat array

    - by Biko
    I thought that would be very common and easy iPhone App. In the main app I connect to database, retrieve values from database (NSDate converted to NSString)n and put into single array. The in one of the views I populate UITableView with elements from the array. UITableView is grouped (sections). I step through array to discover number of sections (change section if new day). How do I retrieve correct element of array in cellForRowAtIndexPath? IndexPath.section and IndexPath.row seem useless as row starts count from zero for each section. If number of rows in each section was the same it would have been easy: [arryData objectAtIndex:(indexPath.row)+indexPath.section*[tblMatchesView numberOfRowsInSection:indexPath.section]]; But number of rows in each section varies... :-)

  • speed up the speed of a sql query to mysql?

    - by fayer
    in my mysql database i've got the geonames database, containing all countries, states and cities. i am using this to create a cascading menu so the user could select where he is from: country - state - county - city. but the main problem is that the query will search through all the 7 millions rows in that table each time i want to get the list of children rows, and that is taking a while 10-15 seconds. i wonder how i could speed this up: caching? table views? reorganizing table structure somehow? and most important, how do i do these things? are there good tutorials you could link to me? i appreciate all help and feedback discussing smart ways of handling this issue!

  • HTML: adjusting the font size according to the screen size

    - by Mike
    I am building an intranet website that is intended to be seen by mobile phones using one of the following resolutions: 240x320, 320x240, 360x640 and 800x352. All content is to be seen covering the full screen. No scroll should be necessary. I have developed, initially for 360x640. When this content is seen on 240x320 or 320x240 the letter is too big and the user has to scroll to see all content. Is there any way to scale the letters down or up automatically, so the content will fit on every screen size? I mean, adjusting the text font size according to the current screen resolution? thanks for any help.

  • Is there a way to make Android tabs slide?

    - by Brian515
    Hi all, I'm new to Android development, and I was wondering if anyone knew either how to make Tabs slide, or how to get a similar effect without tabs. I have quite a few tabs in my application, and it does not look good on devices with smaller screens. Or maybe tabs are not what I am looking for. If you don't know what I'm talking about, I'd like to reproduce something similar to Photoshop.com Mobile's effects screen. I know this is possible. Thanks in advance!

  • Javascriptlibrary more efficient than Rickshaw for realtime visualizations

    - by dan kutz
    I want to visualize data as time-series graphs on mobile devices(tablets) and therefore stumbled upon rickshaw, which is based on D3. First I must say I was a little bit confused when I realized that realtime in web design is defined totally different to realtime in engineering which has fixed(and often very short) timeframes. Anyway my aim is to visualize the data as fast as possible, and on older tablets visualization with rickshaw is quite slow. Can anybody recommend another library, which may be more efficient in rendering? Or is there no way out and I have to go native? regards Dan.

  • AIR for Android, Flash iphone packager, Playbook support for streaming camera and choosing camera

    - by mswallace
    I am wondering if anyone can definitively tell me if Flash / AIR can find all these mobile devices front facing camera and use RTMP to stream the video captured ? I would like to create a video conferencing app for these devices. Of course none of them support testing this in the simulators and I don't have the funds to purchase or access all of them that I would like to test. Wondering if anyone can shed some light on this for me. I have seen some posts where they have done this for android but not sure about support for finding a list of cameras, choosing one and streaming from iphone 4 and playbook. thanks for any help on this.

  • Ruby on Rails: How best to escape a string in a model?

    - by williamjones
    I want my application to sanitize html on input rather than on display, so that the fields saved into the database are sanitized. I've been doing this with strip_tags, and it was working great. However, this has the downside that it means the user can't input anything that's bracketed with < and . How can I tell Rails in the model to securely escape tags before saving them to the database? I'd like to not have to call h on the sanitized fields again before using them in the views.

  • Eliminating static properties - What patterns do I have at my disposal?

    - by Jamie Dixon
    I currently have a type that I inject into my controllers that's used for getting and setting session data. I use this so that I can obtain relevant session information as _sessionData.Username rather than using Session["username"]. I'd like to use this session information across all of my views and would previously have done this by making the SessionData members static instead of injecting the SessionData class into my controller. I want to avoid using static members as well as having to pass the object to the view in each controller. What patterns best suit this type of scenario? What do you do to solve this same problem?

  • Is Graphics.DrawImage asynchronous?

    - by Roy
    Hi all, I was just wondering, is Graphics.DrawImage() asynchronous? I'm struggling with a thread safety issue and can't figure out where the problem is. if i use the following code in the GUI thread: protected override void OnPaint(PaintEventArgs e) { lock (_bitmapSyncRoot) { e.Graphics.DrawImage(_bitmap, _xPos, _yPos); } } And have the following code in a separate thread: private void RedrawBitmapThread() { Bitmap newBitmap = new Bitmap(_width, _height); // Draw bitmap // Bitmap oldBitmap = null; lock (_bitmapSyncRoot) { oldBitmap = _bitmap; _bitmap = newBitmap; } if (oldBitmap != null) { oldBitmap.Dispose(); } Invoke(Invalidate); } Could that explain an accessviolation exception? The code is running on a windows mobile 6.1 device with compact framework 3.5.

  • Migrating a simple application from Application Delegate to ViewController Class

    - by eco_bach
    Hi Frst of all wanted to send out a huge thanks for the great feedback and support. I have a simple application working, right now simply loads a sequence of images and alows the user to step thru the images by clicking a button. All of my logic is in my Application Delegate class, with the image loading, initialization of UIImage Views etc happening in my applicationDidFinishLaunching method. My next step is to migrate as much as possible all of the logic from this class to a ViewController, to take advantage of the extra functionality etc in viewcontrollers. All my images and imageViews are initialized like the following in my applicationDidFinishLaunching. img = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@image1.jpg" ofType:nil]]; imgView = [[UIImageView alloc] initWithImage:img]; How would I migrate this to a ViewController based application? Where would I put all of the logic currently in my applicationDidFinishLaunching method, or for loading of images, is it necessary to only load them here? Any feedback, tips, suggestions appreciated.

  • Relation/Sort not working in rails controller?

    - by Elliot
    I have the following relation in my rails app: genre - has many - authors authors - belong to genre and has many books books - belongs to authors and belongs to users (users can add books to the db) in my controller I have: @books=current_user.books(:include => [:author => :genre], :order => 'created_at DESC') While I am able to use the @books variable in my views - nothing is done correctly (i.e. its not showing me only books added by that user, and its not descending by created_at)... any ideas? -- Also I'm using clearance for the user auth, so current_user without the @ in the controller seems to work fine Actually, I think the relation is working, only the sort might not be working...

  • How to build the ViewModel in MVVM not to violate the Single Responsibility Principle?

    - by Przemek
    Robert Martin says: "There should never be more than one reason for a class to change". Let's consider the ViewModel class which is bound to a View. It is possible (or even probable) that the ViewModel consists of properties that are not really related to each other. For small views the ViewModel may be quite coherent, but while the application gets more complex the ViewModel will expose data that will be subject to change for different and unrelated reasons. Should we worry about the SRP principle in the case of ViewModel class or not?

  • How can I type cast EventArgs to have a .point property in c#? [closed]

    - by Sean Smyth
    I'm working with a double click function in c#. the function takes an object and EventArgs as it's parameters: private void gvHL7_DoubleClick(object sender, EventArgs e){ . . . } However, I want to use the .Point property, and EventArgs doesn't have that property. I know that DevExpress.XtraGrid.Views.Grid.GridMenuEventArgs does, but it's saying that's an invalid casting. What type should I cast my EventArgs instance to if I wish to access the .Point property? Edit: The double click function I'm working with is provided by devexpress for their grids.

  • VendInvoiceJour.InvoiceAccount <- VendTable.AccountNum relation

    - by vukis
    Hi. I have following situation: I need to join VendInvoiceJour.InvoiceAccount <- VendTable.AccountNum and take VendTable.Vendgroup. In all cases (queries,or even views) Dynamics ax joins tables VendInvoiceJour.OrderAccount<- VendTable.AccountNum not VendInvoiceJour.InvoiceAccount <- VendTable.AccountNum. I`m trying to use this kind of query: qBdSVendJour = element.query().dataSourceTable(tablenum(VendInvoiceJour)); qBdSVendTbl = qBdSVendJour.addDataSource(tablenum(VendTable)); qBdSVendTbl.relations(true); qBdSVendTbl.joinMode(JoinMOde::InnerJoin); qBdSVendTbl.fetchMode(QueryFetchMode::One2One); qBdSVendTbl.addLink(FieldNum(VendInvoiceJour,InvoiceAccount),FieldNum(VendTable,AccountNum));//(Dynamics ax automaticaly corrects InvoiceAccount to orderaccount in reports if trying this link in morphx)

  • Doing a generic <sql:query> in Grails

    - by melling
    This is a generic way to select data from a table and show the results in an HTML table using JSP taglibs. What is the generic way to do this in Grails? That is, take a few lines of SQL and generate an HTML table from scratch in Grails, including the column names as headers. <sql:query var="results" dataSource="${dsource}" select * from foo </sql:query (# of rows: ${results.rowCount}) <table border="1" <!-- column headers -- <tr bgcolor=cyan <c:forEach var="columnName" items="${results.columnNames}" <th<c:out value="${columnName}"/</th </c:forEach </tr <!-- column data -- <c:forEach var="row" items="${results.rowsByIndex}" <tr <c:forEach var="column" items="${row}" <td<c:out value="${column}"/</td </c:forEach </tr </c:forEach </table The solution to this was answered in another StackOverFlow question. http://stackoverflow.com/questions/425294/sql-database-views-in-grails IF SOMEONE WRITES A GOOD ANSWER, I'LL ACCEPT IT. I would like a 100% acceptance on all of my questions.

  • Combining features from other projects in an ASP.NET MVC application

    - by Katie D
    Hello, I am writing an ASP.NET MVC application that combines a set of features from existing applications. The new application is suppose to use UI features and logic created (especially for this purpose) in the existing applications. For that reason I wanted to create in the existing applications some kind of a "blackbox" that I will be able to drop in my new application along with a matching connection string, and it will work independently, binding data on it's own. I thought about using partial views, but I am having trouble with passing the model data to it, since the controller of the new application should not know about the model of the existing applications. I can not use ASP.NET WebForms, since my application should be a "postback-less" application, and ASP.NET AJAX toolkit or frameworks alike are out of the question. Any help would be greatly appreciated. Thank you, Katie

  • iPhone CSS and Display Testing

    - by Philip Arthur Moore
    Hi All. I recently coded and launched a website that displays consistently across Chrome, Firefox, Opera, IE8, IE7, and Safari. According to site visitors, though, the signup forms at the top and bottom of the site are mangled on the iPhone. I do not own an iPhone and I rarely test sites on the iPhone, and I would really hate to purchase it or an iPod Touch for the sake of occasional CSS/display testing. Question: is there a site online or a program I can use (I'm on Windows 7) for iPhone testing? An alternative question might be why the signup forms aren't displaying properly on the iPhone, when they look fine in all other browsers and a few other mobile devices that I've used? Many thanks.

  • Code is exectuting but the view is not loading when called form a function?

    - by wolverine
    I have a viewBased application with the viewController class mainView. In it I am loading various views(different nibs) depending upon certain actions that I do. I have added a popoverController with a barbutton in the mainView. Its intialized with a tableviewController class named popClass. When I select certain row in the popover, I want the view in my mainView to load someother view(as I do when i do certain actions). For that I have written a function in mainView Controller class and is calling it from the popOver class. Function and the lines of code are executing but nothing is happening. Even the log lines are printed but no action takes place. What is the problem? OR is there anyother way to make the view change in mainView by using the popover?

  • Zend not autoloading models

    Ok, this is driving me nuts! I have a directory structure as follows: application - modules -- default --- controllers --- models ---- DbTable ---- Cachmapper.php --- views My config file looks like this [production] phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH "/../library" bootstrap.path = APPLICATION_PATH "/Bootstrap.php" bootstrap.class = "Bootstrap" resources.frontController.moduleDirectory = APPLICATION_PATH "/modules" resources.modules[] = The application seems to work, if I navigate to localhost, it correctly goes to the index controller. But, for some reason it refuses to load any models. Fatal error: Class 'Model_Cachmapper' not found in .............................../application/modules/default/controllers/IndexController.php on line 26 Ideas? Thanks
