  • show activity indicator while loading ViewController

    - by Crystal
    I have a ViewController that takes time to load its views. When I run Instruments, I see from the home screen, if I tap on the icon that pushes that view controller onto the stack, it's half laying out the views, and half getting the data for the views. I tried adding an activity indicator to display on the home screen over the button when the button is pressed to push the LongRunningViewController onto the stack. So I basically do this: - (IBAction)puzzleView:(id)sender { dispatch_async(dispatch_get_main_queue(), ^{ [self.activityIndicator startAnimating]; }); PuzzleViewController *detailViewController = [[[PuzzleViewController alloc] init] autorelease]; [self.navigationController pushViewController:detailViewController animated:YES]; [self.activityIndicator stopAnimating]; }

  • How to authorize my app with Facebook

    - by xximjasonxx
    I know I have seen apps that log me in using Facebook but never present me with an authorization screen. I can not, for the life of me, figure out how to do this with Windows Phone 7. The best I have been able to get is using the Facebook for C# SDK to get the authorization screen in a WebView. This looks hideous and the page does not even appear to be mobile ready. I have searched high and low for an answer and have found nothing. Wondering if anyone can point me in the right direction to getting this to work? Thanks in advance

  • How do I change the Unit:Characters in Matlab?

    - by Jonas
    For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

  • Specific position for tooltip

    - by Fiona
    Hello, I have a layer which opens up as a tooltip everytime I hover a button. I simply did that by creating a JS function which displays or hides the layer. Now, I am not a pro in JavaScript. My problem is the following: when the button is scrolled towards the top oft he screen I want the tooltip opening below – and if the button is near the bottom of the screen I want the tooltip opening above. Right now I just did it with absolute positioning. But obviously that doesnt do the trick. Who can help? Thanks!

  • How do I display and calculate numbers from a database on iPhone?

    - by JoshD
    I am new to designing apps and have a basic understand of Ob-C and how everything works. What I would like to do is have two tabs, one is a home screen that displays numbers and percentages that are entered on the second tab. The user will be able to store that information and refer back to it and update it. What is the best way to complete that math from the database to the "home screen"? Any tutorials, advice is great! Thanks.

  • JavaScript - Multiple signals received after click

    - by Angelo A
    I'm creating a webapp using jQueryMobile. When I'm using the app and I click a button it runs the script multiple times. For example: I have a submit button: <input type="submit" id="login-normal" value="Login" /> And I have this JavaScript for debugging on which this error occurs: $("input#login-normal").live('click',function() { console.log("Test"); }); On the very first click it works (and it goes to another screen for example), but when I go back to that screen and I click again, it outputs multiple console.logs

  • Is it possible to create a Service that listens for hardware key presses?

    - by VoteBrian
    I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service" public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.

  • Wpf Window resizes when computer is locked.

    - by Chris
    I have a Window set to the height and width of my monitors: var r = System.Drawing.Rectangle.Union( System.Windows.Forms.Screen.AllScreens[0].Bounds, System.Windows.Forms.Screen.AllScreens[1].Bounds ); Height = r.Height; Width = r.Width; This is all fine until I Lock my computer (WIN+L), when I come back the window has resized itself to be on one monitor only. What I want to do is prevent the decrease in size, as I'm drawing on a canvas on the second monitor, and when the resize occurs, this is all lost.. Any thoughts on how I can prevent this? Cheers!

  • deep zoom is not displayed

    - by George2
    I am using VSTS 2008 + C# + .Net 3.5 + Windows Vista Enterprise x86. I have used Silverlight Deep Zoom composer tool to export my composed images into Siverlight type.

  • iPhone/Safari: fixed div sticks in the middle of the page when coming back by "history.back(-1)"

    - by praegustator
    Having a problem with fixed div using iPhone's Safari. I know that in iOS 5 the functionality for position:fixed have been added. My div is positioned at the top of the screen and behave pretty good, anyway, there are some bugs during scrolling. But what actually makes me angry - it is the position of this div after coming back to the current page clicking on javascript:history.back(-1) link. The fixed div sticks in the middle of a screen. When I try to scrool, it jumps back on the right position. Is there any cure for the bug?

  • How to check if people liked my Facebook FanPage

    - by user2372419
    There are many questions and answers about this. But nowadays Facebook changes their Privacy. Any Application that request for user_likes permission must be review by Facebook before using. I've tried many times to explain to Facebook review team about my app, but they did not accept, because my application (a web game using HTML5 and JavaScript) require people like my fan page before play. So my question is: Is there any to bypass Facebook privacy? I have a Like Box on the same page as the game screen (where i need to check Like), so any solution (like: analyze DOM elements, capture screen can pass through image recognition) will fine.

  • C++ - Creating folder method

    - by Matthew
    I have the following method in C++: void create_folder(LPCWSTR full_folder) //Method to create folder in case it does not exist { if(!CreateDirectory(full_folder,attr)) //Checking whether the folder already exists { switch (GetLastError()) { case ERROR_ALREADY_EXISTS: printf("The folder already exists!\n\n"); break; case NULL: printf("The folder does not exist!\n\n"); printf("The folder was created successfully!\n\n"); break; } } } In case the folder already exists, the correct message is displayed on the screen. However, if the folder does NOT exist, nothing is displayed on the screen, that is, the part identified by case NULL is not executed. How can I solve this problem? In other words, how can I get the code after the case NULL to run if the folder does not exist?

  • Do Portable Class Libraries work with .net 3.5?

    - by Eric
    I am running Windows 8 and have both Visual Studio 2010 Ultimate w/sp1 and Visual Studio 2012 Ultimate and I am trying to create a Portable Class Library that supports .net 3.5 and greater. When I first try to create a PCL I get a screen like this: I noticed that .net 3.5 is not in the list so I clicked on "Install additional frameworks" and found a Targeting Pack for version 3.5. But when I download and run "dotnetfx35setup.exe" nothing happens. And when I go back into VS and try to create a new Portable Class Library, it lists the same target frameworks as before. I have also turned on the Windows Features for .NET Framework 3.5 and am now out of ideas. Here is a screen shot in case I missed something else. Thanks,

  • View OS X Desktop on windows remotely at higher resolution then hosting machine

    - by Elijha
    I have a new macbook air 11, which I do some web based programming on, I have a windows box with a 1920x1200 display which I'd like to use to view the mac desktop and keep working at home when I can - taking advantage of the higher resolution screen and full sized keyboard/mouse. I don't think VNC or such is the answer I'm looking for as it would restrict the display to the airs 1366x768 - negating the main benefit more lines of text on screen. From some rudimentary googleing I think I'm after some sort of x-windows / x-11 remote display. But I'm not a Linux user and any discussion seems to be about linux os x or windows Linux setups. Can anyone provide a clear set of instructions on how to do this or an application that can do this.

  • Basic CSS: having unordered list extend beyond container div?

    - by Tony
    Hi. It's been a bit since I've gotten really into CSS work, I'm trying to make a simple layout with a menubar. The idea is to have a container holding everything in the center of the screen and have a menubar (unordered inline list) that runs the full length of the screen but the list items to be contained in the container. See this pic for a visual example ps. I know this isn't true "programming", but this seemed like the most appropriate place to post this question. Let me know if there's a better /r/ for this to go.

  • Android RealViewSwitcher : How to start on second page?

    - by DarcCode
    i'm using RealViewSwitcher I got from this site. It works perfectly on my code, but I don't have any idea how to set the initial current screen to second or third screen. the method setCurrentScreen(int) doesn't affect anything and if I change the for loop inside the onLayout() method from for (int i = 0; i < count; i++) {...} into for (int i = 1; i < count; i++){...} It does starts in page two, but you can't go to page one. Any idea how to start on page two?

  • When i add a bitmap to an array list the last element is duplicated in previous indexes

    - by saxofone2
    I'm trying to implement a personal way of undo/redo in a finger paint-like app. I have in synthesis three objects: the Main class (named ScorePadActivity), the relative Main Layout (with buttons, menus, etc, as well as a View object where I create my drawings), and a third object named ArrayList where i'm writing the undo/redo code. The problem is, when I press the undo button nothing happens, but if I draw anything again "one-time" and press undo, the screen is updated. If I draw many times, to see any changes happen on screen I have to press the undo button the same number of times I have drawn. Seems like (as in title) when I add a bitmap to the array list the last element is duplicated in previous indexes, and for some strange reason, everytime I press the Undo Button, the system is ok for one time, but starts to duplicate until the next undo. The index increase is verified with a series of System.out.println inserted in code. Now when I draw something on screen, the array list is updated with the code inserted after the invocation of touchup(); method in motionEvent touch_up(); } this.arrayClass.incrementArray(mBitmap); mPath.rewind(); invalidate(); and in ArrayList activity; public void incrementArray(Bitmap mBitmap) { this._mBitmap=mBitmap; _size=undoArray.size(); undoArray.add(_size, _mBitmap); } (All Logs removed for clear reading) The undo button in ScorePadActivity calls the undo method in View activity: Button undobtn= (Button)findViewById(R.id.undo); undobtn.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { mView.undo(); } }); in View activity: public void undo() { this.mBitmap= arrayClass.undo(); mCanvas = new Canvas(mBitmap); mPath.rewind(); invalidate(); } that calls the relative undo method in ArrayList activity: public Bitmap undo() { // TODO Auto-generated method stub _size=undoArray.size(); if (_size>1) { undoArray.remove(_size-1); _size=undoArray.size(); _mBitmap = ((Bitmap) undoArray.get(_size-1)).copy(Bitmap.Config.ARGB_8888,true); } return _mBitmap; } return mBitmap and invalidate: Due to my bad English I have made a scheme to make the problem more clear: I have tried with HashMap, with a simple array, I have tried to change mPath.rewind(); with reset();, new Path(); etc but nothing. Why? Sorry for the complex answer, i want give you a great thanks in advance. Best regards
