  • Using PDF in iPad

    - by RVN
    Has Anyone tried using PDF in iPad Application, using CGPDf functions. I have used this in iPhone and it works perfectly , but when i use the same code in iPad , the Page are Shrunk in size, after a try outs i set the Scale as follows CGContextScaleCTM(context,1.85, -1.80); This time the it fits the screen perfectly , but that was just a trial and error , why does it not fit the screen as in iPhone, i have set the view size correctly too. Anyone having a clue about it please let me know. and also this is my drawRect method where i am drawing the PDF page void drawRect:(CGRect)rect{ UIGraphicsBeginPDFPage(); CGContextRef context = UIGraphicsGetCurrentContext(); CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNumber); CGContextSaveGState(context); CGContextTranslateCTM(context, 1.0, self.frame.size.height); CGContextScaleCTM(context,1.0, -1.0); CGContextDrawPDFPage(context, page); CGContextRestoreGState(context); } Thanks

  • How to intercept UIScrollView contentOffset changes from UITableView subclass?

    - by mystify
    Actually, a UITableView is a UIScrollView (inherits from that). Now, I made a UITableView subclass and added this line of code to it: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { NSLog(@"contentOffset: %@", NSStringFromCGPoint(self.contentOffset)); } For some reason this is never called when I scroll the table view. But since UITableView has a delegate property on it's own, I assume that it must implement UIScrollViewDelegate protocol and is the delegate for the scroll view itself. Isn't it? How could I intercept scroll position changes? I want to read them only. Probably I couldn't set them with contentOffset, right?

  • Popover with embedded navigation controller doesn't respect size on back nav

    - by quixoto
    I have a UIPopoverController hosting a UINavigationController, which contains a small hierarchy of view controllers. I followed the docs and for each view controller, I set the view's popover-context size like so: [self setContentSizeForViewInPopover:CGSizeMake(320, 500)]; (size different for each controller) This works as expected as I navigate forward in the hierarchy-- the popover automatically animates size changes to correspond to the pushed controller. However, when I navigate "Back" through the view stack via the navigation bar's Back button, the popover doesn't change size-- it remains as large as the deepest view reached. This seems broken to me; I'd expect the popover to respect the sizes that are set up as it pops through the view stack. Am I missing something? Thanks.

  • UIScrollView setZoomScale not working ?

    - by iFloh
    Hi, I am struggeling with my UIScrollview to get it to zoom-in the underlying UIImageView. In my view controller I set - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myImageView; } In the viewDidLoad method I try to set the zoomScale to 2 as follows (note the UIImageView and Image is set in Interface Builder): - (void)viewDidLoad { [super viewDidLoad]; myScrollView.contentSize = CGSizeMake(myImageView.frame.size.width, myImageView.frame.size.height); myScrollView.contentOffset = CGPointMake(941.0, 990.0); myScrollView.minimumZoomScale = 0.1; myScrollView.maximumZoomScale = 10.0; myScrollView.zoomScale = 0.7; myScrollView.clipsToBounds = YES; myScrollView.delegate = self; NSLog(@"zoomScale: %.1f, minZoolScale: %.3f", myScrollView.zoomScale, myScrollView.minimumZoomScale); } I tried a few variations of this, but the NSLog always shows a zoomScale of 1.0. Any ideas where I screw this one up?

  • Updating multiple Sprites - AS3 performance best practices

    - by dani
    Within the container "BubbleContainer" I have multiple "Bubble sprites". Each bubble's graphics object (a circle) is updated on a timer event. Let's say I have 50 Bubble sprites and each circle's radius should be updated with a mathematical formula. How do I organize this logic? How do I update all Bubble sprites within the BubbleContainer? (should I call a bubble.update() function or make a temporary reference to the graphics object?) Where do I put the Math logic? (as static functions?)

  • Sub-classing TreeView in C# WinForms for mouse over tool tips

    - by Matt
    Ok, this is a weird one. The expected behaviour for a TreeView control is that, if ShowNodeToolTips is set to false, then, when a label for a tree node exceeds the width of the control (or, more accurately, it's right hand edge is past the right hand edge of the client area), then a tooltip is shown above the node showing the full item's text. I'd like to disable that, because the above semantic doesn't always work, depending on what the treeview is contained within. So I have rolled my own, and got the tooltips to work (and line up better than the default one!) - but I would like to be able to disable the 'default' behaviour for situations where it would work natively. So, can anyone point me in the right direction as to which message to post to the TreeView in order to disable that behaviour? I have looked at the windows control reference, but couldn't find anything that looked like it might be the one. Thanks Matt

  • JSLint reports "Unexpected dangling" character in an underscore prefixed variable name

    - by Zhami
    I know that some people consider the presence of a leading underscore to imply that a variable is "private," that such privacy is a fiction, and assume this is why JSLint reports such names with an error message. I use Google Analytics on a Web site I am building. I make reference to GA's variables, such as "_gaq." I am trying to get my JS code to be 100% JSLint clean (I'm not religious about my coding style, and so will go with Mr. Crockford's counsel). That said, I can't do anything about Google's variables names... so, I guess I can't get 100% "clean." I post here in case I've misunderstood the message, and can do something to comply with JSLint practices.

  • Automate Google Chrome extension installation

    - by gtaborga
    Hi everyone, I am working on creating a Google Chrome extension. We have it included in an automated build system and since it is constantly being worked on we need a solution to be able to package the extension as a .crx file which according to http://code.google.com/chrome/extensions/packaging.html can easily be scripted. My question is after packaging the extension is there a known method either through the command-line or some other programmatic way, to install the newly packaged extension in an automated manner? If someone knows how or has any reference material that I can be pointed towards I would greatly appreciate any help that is offered. Thank you.

  • How to detect touches on MPMoviePlayerController window and still having the standard playback cont

    - by gkedmi
    Hello I have the MPMoviePlayerController set up to play a movie.I want to detect a touch on the movie for bringing up few buttons.I used the code : // The movie's window is the one that is active UIWindow* moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; // Now we create an invisible control with the same size as the window UIControl* overlay = [[[UIControl alloc] initWithFrame:moviePlayerWindow.frame]autorelease]; // We want to get notified whenever the overlay control is touched [overlay addTarget:self action:@selector(movieWindowTouched:) forControlEvents:UIControlEventTouchDown]; // Add the overlay to the window's subviews [moviePlayerWindow addSubview:overlay]; but then the play back controllers doesn't appear , I guess because the player window doesn't get the touch.how can I keep the player controllers and still detects touches? thanks

  • Memory leak in xbap application

    - by Arvind
    Hi, We are using many custom controls by inheriting form the WPFcontrols as the base and customizing it for our need. However, the memory used by these controls are not released, even after pages using the controls are closed, until the whole application is closed. As these application has to work for a whole day performance decreases as more and more memory gets held up. When we profiled our page we found that the controls where not getting collected as there where some binding reference or some borders or brushes etc not getting cleared from that control. We tried to use the Unload event of the controls to remove the events and some references from the control. This reduced the leak to some extent but this was slowing down closing of the page also the unload event was getting triggered when the control was even collapsed. Is there any other ways to overcome the leak? Are there any best practices to prevent memory leaks? Thanks Arvind

    Hi, I'm working on creating a grouped table view. The data is being loaded alright, but in the grouped view there are a lot of white empty spaces. They get populated after I scroll up and down a few times. Help? Here's my getCellForRowIndexAtPath method: static NSString *Id= @"CustomDiagChargeID"; CustomCellDiagCharges *cell = (CustomCellDiagCharges *)[tableView dequeueReusableCellWithIdentifier:Id]; if(cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCellDiagCharges" owner:self options:nil]; for (id oneObject in nib) { if([oneObject isKindOfClass:[CustomCellDiagCharges class]]) cell = (CustomCellDiagCharges *) oneObject; } } NSUInteger row = [indexPath row]; DiagDetails *rowData = [preferences getDiagElementAt:indexPath.section row:row]; cell.code.text = rowData.ICD9Code; cell.desc.text = rowData.ICD9Desc; return cell; Thanks, Teja.

  • Debugging FLEX/AS3 memory leaks

    - by Scott Evernden
    I have a pretty big Flex & Papervision3D application that creates and destroys objects continually. It also loads and unloads SWF resource files too. While it's running the SWF slowly consumes memory til about 2GB when it croaks the player. Obviously I am pretty sure I let go of reference to instances I no longer want with expectation the GC will do its job. But I am having a heck of a time figuring out where the problem lies. I've tried using the profiler and its options for capturing memory snapshots, etc - but my problem remains evasive. I think there are known problems using debug Flash player also? But I get no joy using the release version either. How do you go about tracking down memory leak problems using FLEX/AS3 ? What are some strategies, tricks, or tools you have used to locate consumption

  • ClickOnce and mageUI adding custom file folder problems

    - by Leszek Wachowicz
    What I do: Publishing .Net 3.5 application via VS, or msbuild (whatever), and now I need to insert to the published application separate directory (Modules - not added as a reference to the project - our project architecture does not allow this). So I'm copying the folder to published location then runs mageUI.exe select the application manifest and then the problems starts. As I press the populate button it's adding also hidden directory? So I remove the directory, after I want to save the manifest file I get the "Warning MSB3110: Assembly 'NAME.Shell.application.deploy' has mismatched identity 'NAME.Shell.application', expected file name: 'NAME.Shell.application.application'". Did you have the same problems, according to http://smartclient.codeplex.com/Project/Download/FileDownload.aspx?DownloadId=5060 it should be easy as 1-2-3 but it's not.

  • Excel tab sheet names vs. Visual Basic sheet names

    - by SteveNeedsSheetNames
    It seems that Visual Basic can not reference sheets according to user-modified sheet names. The worksheet tabs can have their names changed, but it seems that Visual Basic still thinks of the worksheet names as Sheet1, etc., despite the workbook tab having been changed to something useful. I have this: TABname = rng.Worksheet.Name ' Excel sheet TAB name, not VSB Sheetx name. Thanks, Bill Gates. but I would like to use sheet names in Visual Basic routines. The best I could come up so far is to Select Case the Worksheet Tab vs. Visual Basic names, which doesn't make my day. Visual Basic must know the Sheet1, Sheet2, etc., names. How can I get these associated with the Excel tab names so that I don't have to maintain a look-up table which changes with each new sheet or sheet tab re-naming? Thanks in advance for your replies.

  • Extracting glyph-path information from ttf files

    - by Anonymous Coward
    I'm trying to figure out a way to extract the information encoded in ttf files. namely: The char-to-glyph table and the individual glyph path data. Does anyone have a good reference explaining the ttf file structure, or some other solution? Keep in mind that I'm not interested in any libraries that can do it for me either (unless they are open source and I can see how they are doing it). The "master" goal is to implement it in Javascript. Thanks!

However I can't find out what I'm meant to use instead, and how to implement it. Below is the code surrounding the stringWithContentsOfURL line in case you need it for reference. NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv", [addressField.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]]; NSArray *listItems = [locationString componentsSeparatedByString:@","]; Thanks.

  • New Facebook FQL table vs. Grap API

    - by PanosJee
    Hello everyone I just read the new User fql table fields at http://developers.facebook.com/docs/reference/fql/user As I can see a lot of the fields have been deprecated such as work_history or books and movies. It is quite essential for my app to get all those fields for my user's friends in a single fql query. If i am not wrong the only way to do this is to get those extra fields using the Graph API by requesting them seperately for every friend of my user. Is there any way to do it in a more efficient way without so many calls? Can I subscribe to real time updates for the request fields for my user's friends (i do not care about the logged in user data)? Thank you a lot
