  • Add blank cell at end of UITable

    - by Michael
    I'm trying to add an additional cell for custom content as the last cell in a tableView, without altering the dictionary that creates the other content of the table. I think the place to add it is in cellForRowAtIndexPath rather than adding one to the numberOfRowsInSection, which just crashes if I do. I get a cellCount from the dictionary that creates the data for the table, then in cellForRowAtIndexPath, I have: if (indexPath.row == cellCount) { ... stuff goes here return cell; } of course, this never gets called. If I do if (indexPath.row == cellCount -1) it overwrites the last cell with content. I can get this to work if I add a blank entry into the xml from which I am populating the dictionary, but that's ugly. Example code would be neat!

  • Refactored App Engine project - now Eclipse is infinitely building the project without end

    - by Yog
    I renamed some files in my App Engine project and refactored code, changing references to variables. Everything seemed fine until I changed the references in the web.xml for the project. Then I got a complaint about some error with the DataNucleus enhancer and now the project build process is stuck at 22%. I tried stopping Eclipse and restarting but the build process keeps hanging. Any tips on how to clean out whatever it's getting stuck on?

  • Creating ODT and PDF files as end result

    - by Bill Zimmerman
    Hello, I've been working on an app to create various document formats for a while now, and I've had limited success. Ideally, I'd like to dynamically create a fairly simple ODT/PDF/DOC file. I've been focusing my efforts on ODT, because it is editable, and open enough that there are several tools which will convert it to any of the other formats I need. The problem is that the ODT XML files are NOT simple, and there aren't any good-quality API's I could find (especially in python). So far, I've had the most success creating a template ODT file, and then manipulating the DOM in python as needed. This is ok generally, but is quickly becoming inadequate and requires too much tweaking every single time I need to alter one of the templates. The requirements are: 1) Produce a simple document that will have lists, paragraphs, and the ability to draw simple graphics on the page (boxes, circles, etc...) 2) The ability to specify page size, and the different formats should generally print the exact same output when sent to a printer My questions: 1) Are there any other ways I can produce ODT/PDF/DOC files? 2) Would LaTeX be acceptable? I've never really used it, does anyone have experience converting LaTeX files into other formats? 3) Would it be possible to use HTML? There are a lot of converters online. Technically you can specify dimensions in mm/cm, etc..., but I am worried that the printed output will differ between browsers/converters.... Any other ideas?

  • Request attributes in jsf / icefaces behaves strange (survive request end)

    - by hubertg
    I have the following code in a listener method: FacesContext.getCurrentInstance().getExternalContext().getRequestMap().put("time", new Date()); When a button is clicked the following code is executed System.out.println(FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("time")); One could except that "time" is null when the listener was not executed while processing the current request, but: it seems like the "time" object survives the request processing. So when "time" has been set sometimes in the past it stays there... can anybody explain this? Thanks.

  • Ruby: wait for system command to end

    - by Ignace
    Hey all, I'm converting an xls 2 csv with a system(command) in ruby. After the conversion i'm processing this csv files. But the conversion is still going when the program wants to process the files. So at that time they are non existant. Can someone tell me if it's possible to let Ruby wait the right amount of time for the system command to finish? Right now i'm using sleep 20 but if it will take longer once, it isn't right of course... Thanks!

  • how to find end of scroll value for HorizontalScrollView

    - by DroidCoder
    i need to implement following scenario, here i have two horizontalScrollViews the upper scrollView is a main menu and lower scrollView is a submenu. when i scroll main menu,the menu which comes under center arrow will show its submenu in lower scrollview and from the lower scrollview, the submenu which comes under center arrow shows the screen for that sub-menu. here's my requirement: i've implemented it using HorizontalScrollViews and ViewFlipper and also it works but it will give correct result only when i scroll it slowly and not when scroll fast. i've used onTouch() method with a ACTION_UP event,so when i release finger from screen it will gives me getScrollX() position at that point but here i need getScrollX() position when scroll is finished/stop. here's my code:- @Override public boolean onTouch(View v, MotionEvent event) { switch (v.getId()) { case R.id.mHorizontalScrollViewMain: if (event.getAction() == KeyEvent.ACTION_UP) { Log.d("test", " " + hsvUpperTab.getScrollX() + " , "+ mViewFlipper.getChildCount()); getUpperTabScrolled(hsvUpperTab.getScrollX()); } break; case R.id.mHorizontalScrollViewSub: if (event.getAction() == KeyEvent.ACTION_UP) { Log.d("test1", " " + hsvLowerTab.getScrollX()); getLowerTabScrolled(hsvLowerTab.getScrollX()); } default: break; } return false; }

  • Application_End() cannot access cache through HttpContext.Current.Cache[key]

    - by Carl J.
    I want to be able to maintain certain objects between application restarts. To do that, I want to write specific cached items out to disk in Global.asax Application_End() function and re-load them back on Application_Start(). I currently have a cache helper class, which uses the following method to return the cached value: return HttpContext.Current.Cache[key]; Problem: during Application_End(), HttpContext.Current is null since there is no web request (it's an automated cleanup procedure) - therefore, I cannot access .Cache[] to retrieve any of the items to save to disk. Question: how can I access the cache items during Application_End()?

  • How do I display a view as if it's the front page via a module?

    - by Justin
    I have a simple view that feeds a home page. I have a custom module that registers some specific URLs in hook_menu that I pass into my module so I can pass them as arguments into the view. I can get the module to display the view all right, but it doesn't use the teaser/is_front view that outputs when I access the home page. I looked through the APIs but I can't seem to figure out how I can output the view via my module as if it's the front page, meaning $is_front is true and the teasers would appear. The reason I'm not passing in the arguments via the URL bar into the view itself is: My argument list is known and finite The argument order is mixed, meaning I will sometimes have /argument1, /argument1/argument2 or just /argument2. I only want to capture the first level URL as an argument for specific, known strings (e.g. I don't want to pass /admin into my view but I do want to pass in /los-angeles, which I register in the menu system via hook_menu in my module) Here are some examples to make this more clear: /admin - loads the admin page /user - loads the login page /boston - passes into the first argument of the view; shows in front/teaser mode / - shows view with no arguments /bread - passes into argument 2 of the view; shows in front/teaser mode /boston/bread - Passes into argument 1 and 2 of the view; shows in front/teaser mode Maybe I'm going about this the wrong way? Or perhaps there is a way to have a module load a view and somehow set front/teaser mode? Details: Drupal 6, PHP 5, MySQL 5, Views, CCK

  • Can't append space at end of NSString

    - by Sam V
    I have a UITextView in which I want the initial value to be "@username " (notice the space after the username). This way the user can start typing right away without having to tap space. So I do: textView.text = [NSString stringWithFormat:@"@%@ ", username]; But it seems like it's impossible to have an NSString ending with a space (it always gets stripped out). Am I correct? Is there any workaround for this?

  • PHP reads 1.10 value as 1.1 (0 at end of variable not honored)

    - by adbox

I've never seen this before, and didnt know it could happen. Any ideas on how to prevent this? Working with php5. Thank you, Hudson

  • Is it faster to use a complicated boolean to limit a ResultSet at the MySQL end or at the Java end?

    - by javanix
    Lets say I have a really big table filled with lots of data (say, enough not to fit comfortably in memory), and I want to analyze a subset of the rows. Is it generally faster to do: SELECT (column1, column2, ... , columnN) FROM table WHERE (some complicated boolean clause); and then use the ResultSet, or is it faster to do: SELECT (column1, column2, ... , columnN) FROM table; and then iterate over the ResultSet, accepting different rows based on a java version of your boolean condition? I think it comes down to whether the Java iterator/boolean evaluator is faster than the MySQL boolean evaluator.

At some point the IO thread will not have any new pages to crawl and I want to update my database that this session is complete. How can I best tell when the threads are all done processing and the program can be ended?

  • VIM Disable Automatic Newline At End Of File

    - by Boushley
    So I work in a PHP shop, and we all use different editors, and we all have to work on windows. I use vim, and everyone in the shop keeps complaining that whenever I edit a file there is a newline at the bottom. I've searched around and found that this is a documented behavior of vi & vim... but I was wondering if there was some way to disable this feature. (It wouldbe best if I could disable it for specific file extensions). If anyone knows about this, that would be great!

  • AnimationDrawable, when does it end?

    - by Syb
    I know there have been several people with the same question. Which is: How do i know when a frame by frame animation has ended? I have not had any useful answer on fora i visited. So i thought, let's see if they know at stackoverflow. But I could not sit still in the mean time, so i made a work around of this, but it does not really work the way i would like it to. here is the code: public class Main extends Activity { AnimationDrawable sybAnimation; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView imageView = (ImageView)findViewById(R.id.ImageView01); imageView.setBackgroundResource(R.anim.testanimation); sybAnimation = (AnimationDrawable) imageView.getBackground(); imageView.post(new Starter()); } class Starter implements Runnable { public void run() { sybAnimation.start(); long totalDuration = 0; for(int i = 0; i< sybAnimation.getNumberOfFrames();i++){ totalDuration += sybAnimation.getDuration(i); } Timer timer = new Timer(); timer.schedule(new AnimationFollowUpTimerTask(R.id.ImageView01, R.anim.testanimation_reverse),totalDuration); } } class AnimationFollowUpTimerTask extends TimerTask { private int id; private int animationToRunId; public AnimationFollowUpTimerTask(int idOfImageView, int animationXML){ id = idOfImageView; animationToRunId = animationXML; } @Override public void run() { ImageView imageView = (ImageView)findViewById(id); imageView.setBackgroundResource(animationToRunId); AnimationDrawable anim = (AnimationDrawable) imageView.getBackground(); anim.start(); } } basically I make a timertask which is scheduled with the same time as the animation to take. In that run() I want to load a new animation into the imageView and start that animation, this however does not work. Does anyone know how to get this to work, or even better, have a better way to find out when an AnimationDrawable has ended its animation?

    I don't want to use flash. I've found multiple jquery libraries that do this. Right now I'm using this one: http://demo.webdeveloperplus.com/ajax-file-upload/ The problem is they all use PHP. I tried just pointing it at my servlet instead of the PHP file, but it never gets called.

  • Span with white-space style in IE (7) applied _past_ end of span

    - by WaldenL
    We've got an application where users can enter "notes" into a rich edit control (Telerik's RedEditor, but that doesn't matter here). We had a user enter notes from w/in Safari that had a <span></span> in the middle of the note, and that span had a style on it specifying white-space:pre The HTML of the note was in the form of: <div> This is a note <span class="Apple-tab-span" style="white-space: pre; "> </span> and here's more of the note. </div> Simple enough, the style should apply to the span, and the span had 4 spaces in it. There should have been 4 spaces in the resulting output. Here's the problem. IE seems to apply that white-space: pre; style not only to the span, but to the enclosing div! Therefore, this long line that should have wrapped since it's not in the span, now pushed the document out until the line fits on the page. What am I missing. I know IE has problems, but this doesn't seem right, even for IE. So, the question(s): 1) Am I correct that the white-space attribute should only have applied to the span? 2) Can this be resolved somehow? Remember, I'm not in control of the content being entered. And it's entered from a mac w/Safari and being viewed in IE. Edit: The doctype on the page in question is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

  • C++ detecting end of file

    - by xbonez
    I have a C++ program that is reading in info from a file, that stores info seperated by "$$$$". An example of how the file looks is: abc bcd $$$$ def $$$$ qwe gfh $$$$ How can I detect the file has ended, without using the eof() function? I have it set like this, getline(sin,temp) if (temp=="$$$$") { } After reading the last set of four dollars, how can I check the next line to ensure another set of data isn't beginning, and that the file has ended? If the file has indeed ended, I plan on using a boolean flag to terminate the while loop.
