  • Getting GPU clock speeds with SetupDiEnumDeviceInfo

    - by user157078
    Hi everyone! I posted a question earlier regarding obtaining GPU clock speeds, but I guess the thread appeared as already answered since someone had replied to it. I'd been advised by one of your members to try extracting GPU clock speeds using SetupDiEnumDeviceInfo. However, I looked around at some examples, like this one: http://www.codeproject.com/KB/system/DevMgr.aspx and nothing seemed to be displayed about the clock speed. Could someone please elaborate on how to achieve this, if at all possible? Thanks again

  • Setting Priorities on Buttons

    - by JONY
    Hello Android Developers, I am trying to figure out how to set priorities on imagebutton. I want to have a layout with a bunch of Icon or buttons that can be selected either by touch, radio, or checked box. As these images are selected they are set on queue to be displayed in order of Precedence. (that is to be pre-determined). The images are displayed once the main action button is touched. Any help will be greatly appreciated. Thank you,

  • Framework for iPhone wait screens

    - by 4thSpace
    I ran across a small framework some time back that someone put together for iPhone wait screens. But now I can't find any trace of it. Does anyone have a link to it? It may not be a framework as much as a few code snippets. But the guy had it all pre-made. You just needed to implement and specify the type of wait screen you wanted.

  • Forwarding first responder to UIScrollView unsuccessful

    - by Winston
    Hello, I am trying to create an image cropping bpx whereby the underlying image can be zoomed an scrolled while the cropping "maskview" layer stays the same and the corners can be dragged in any direction. To achieve this, the ImageView is added to a UIScrollView, and this is added to the SelectionViewController.view . I then add the cropping "maskview" layer to the SelectionViewController.view. I did this instead of adding to the scrollview so that the cropping maskview won't be expanded when the underlying image expands. @interface SelectionViewController : UIViewController <UIScrollViewDelegate> { UIImageView *photoview; // Added to self.scrollview MaskedView *maskedview; // Added to self.view UIScrollView *scrollview; // Added to self.view } The maskview has first responder status and responds accordingly. However, the only event I am interested in the maskview is if any of the corners are dragged (this works fine). The problem I want to try to solve is two-fold: If it is a pinch or zoom gesture, I am trying to forward the responder to the UIScrollview using: [self.nextResponder touchesMoved:touches withEvent:event]; The scrollview does not seem to respond. I have confirmed that the self.nextResponder after the maskedview is the SelectionViewController's view itself. From there, it doesn't seem like the UIScrollview responds. It does respond fine if I remove the cropping maskedview. If I zoom in on the underlying image and the cropping maskview rectangle is still the same, I want to now crop the actual zoomed image. Let's say for the upper left hand corner of the crop box, how can I find what the coordinates translates to in the underlying UIImageView now that the image has been zoomed? Any insight into either of these questions would be appreciated. Thank you, Winston

  • Google Mock for iPhone development?

    - by Cliff
    I have an interesting situation where I am refactoring a bunch of ObjC iPhone code to create a C++ API. I'm a novice to C++ and looking into C++ mocking frameworks to augment the work I'd done using OCUnit and poor man's mocks. I ran across googlemock and wanted to know if anyone has ever used it for iPhone development? Also, how can I share this (or mockpp) with other devs as it is an installable package and doesn't seem to lend itself to checking into a repository?

  • Detecting a Lightweight Core Data Migration

    - by hadronzoo
    I'm using Core Data's automatic lightweight migration successfully. However, when a particular entity gets created during a migration, I'd like to populate it with some data. Of course I could check if the entity is empty every time the application starts, but this seems inefficient when Core Data has a migration framework. Is it possible to detect when a lightweight migration occurs (possibly using KVO or notifications), or does this require implementing standard migrations? I've tried using the NSPersistentStoreCoordinatorStoresDidChangeNotification, but it doesn't fire when migrations occur.

  • Problems pulling data from NSMutableArray for MapKit?

    - by Graeme
    Hi, I have a class (DataImporter) which has the code to download an RSS feed. I also have a view and separate class (TableView) which displays the data in a UITableView and starts the parsing process, storing parsed information in an NSMutableArray (items). Now I wish to add a UIMapView which displays the items in the items NSMutableArray. I'm struggling to transfer the data into the new class (mapView) to show it in the map - and I preferably don't want to have to create a new class to download the data again for the map. Is there a way I can transfer the information from the NSMutableArray (items) to the mapView? Thanks. Code for viewDidLoad MapKit: Data *data = nil; NSString *ilocation = [data locations]; NSString *ilocation2 = @"New Zealand"; NSString *inewlString; inewlString = [ilocation stringByAppendingString:ilocation2]; NSLog(@"inewlString=%@",inewlString); if(forwardGeocoder == nil) { forwardGeocoder = [[BSForwardGeocoder alloc] initWithDelegate:self]; } // Forward geocode! [forwardGeocoder findLocation: inewlString]; Code for parsing data into NSMutable Array: - (void)beginParsing { NSLog(@"Parsing has begun"); //self.navigationItem.rightBarButtonItem.enabled = NO; // Allocate the array for song storage, or empty the results of previous parses if (incidents == nil) { NSLog(@"Grabbing array"); self.datas = [NSMutableArray array]; } else { [datas removeAllObjects]; [self.tableView reloadData]; } // Create the parser, set its delegate, and start it. self.parser = [[DataImporter alloc] init]; parser.delegate = self; [parser start]; }

  • OpenGL depth buffer on Android

    - by kayahr
    I'm currently learning OpenGL ES programming on Android (2.1). I started with the obligatory rotating cube. It's rotating fine but I can't get the depth buffer to work. The polygons are always displayed in the order the GL commands render them. I do this during initialization of GL: gl.glClearColor(.5f, .5f, .5f, 1); gl.glShadeModel(GL10.GL_SMOOTH); gl.glClearDepthf(1f); gl.glEnable(GL10.GL_DEPTH_TEST); gl.glDepthFunc(GL10.GL_LEQUAL); gl.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_NICEST); On surface-change I do this: gl.glViewport(0, 0, width, height); gl.glMatrixMode(GL10.GL_PROJECTION); gl.glLoadIdentity(); GLU.gluPerspective(gl, 45.0f, (float) width / (float) height, 0.1f, 100f); When I enable backface culling then everything looks correct. But backface culling is only a speed-optimization so it should also work with only the depth buffer or not? So what is missing here?

  • Executing codes in viewDidLoad

    In my .m file : (void)viewDidLoad { [super viewDidLoad]; /* Some codes for picker view and slider */ } I used a button to navigate to second view by using the below code: (IBAction)goToPlay{ [self presentModalViewController: secondViewController animated: YES]; } I used another button to go back to first view by using below code: (IBAction)goBack{ [self dismissModalViewControllerAnimated:YES]; } Now the viewDidLoad method is not calling. I had written some codes in viewDidLoad in first view and I want to execute it when pressing goBack button in second view. What should I do? Anyone please help.

  • Adding a dynamic-height UITableView into a scrolling view?

    - by Greg
    Hello all – I'm getting into iPhone development and have hit my first confusing UI point. Here's the situation: My app is tab-based, and the view that I'm confused about has a static featured content image at the top, then a dynamic list below into which X headlines are loaded. My goal is to have the height of the headline table grow as elements are added to it, and then to have the whole view scroll (both featured image on top and headline list below). So, I guess my question comes in two parts: 1) First, how do you set up a dynamic-height table view that will grow as cells are added to it. So far I've only been able to have my tables handle their own scrolling. 2) Then, what is the root NIB view that the featured image and the table should live in to enabled scrolling? I've dropped oversized content into a UIScrollView now, although did seem to have any success with having it automatically scroll. Thanks in advance for any help on this subject!

  • Height of screen in portrait mode only?

    - by user246114
    Hi, How can I get the height of the device for portrait mode? I have to create a bitmap (which is zoomable) and I just want to get a rough idea what the tallest height should be. getResources().getDisplayMetrics().heightPixels; does the above return the height, in portrait mode only? I'm not binding my UI to this absolute value, it's just a rough fit, Thanks

  • Optimising local image loading/rendering on iPhone

    - by Tricky
    Hi, I'm looking to create an interface where the user can navigate through large volumes of images. Each image has a thumbnail of 128x128 that I wish to display and will be kind of similar to coverflow in operation. I have this all working in principle but am becoming stuck when navigating through content at speed. The interface begins to stutter and becoming jerky. I believe this is primarily because of disk i/o and the cost of rendering each image. Is there anyway this can be handed over to a seperate thread simply? Defaulting to a greyed out thumbnail until the image has loaded? How have Apple managed to achieve this in coverflow? Many thanks,

  • UIScrollView resizes when a UIViewController is pushed in UINavigationController. Why?

    - by user210504
    Hi! When I push a UIViewController within a UINavigationController, the UIScrollView in the view changes dimensions. Now even I am trying to resize the UIScrollView. It wont simply resize. It maintains the framework dimensions. Any idea why this would be happening. Example: My NIB has a view which has a scrollview with dimensions (320, 430) now when I push the UIViewController associated with the view the scrollview still shows dimensions has 320, 430, but is drawn much smaller then 320,430 Any suggestions in this regard.

  • How to customize the content of each page using Page Control and UIScrollView?

    - by viper15
    I have problem with customizing each page using pagecontrol and UIScrollView. I'm customizing Page Control from Apple. Basically I would like to have each page different with text and image alternately on different page. Page 1 will have all text, Page 2 will have just images, Page 3 will have all text and goes on. This is original code: // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; } As you can see, this code shows only Page 1, Page 2 etc as you scroll right. I tried to put in this new code but that didn't make any difference. There's no error. I know this is pretty simple code. I don't why it doesn't work. I declare pageText as UILabel. // Set the label and background color when the view has finished loading. - (void)viewDidLoad { pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1]; self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber]; if (pageNumber == 1) { pageText.text = @"Text in page 1"; } if (pageNumber == 2) { pageText.text = @"Image in page 2"; } if (pageNumber == 3) { pageText.text = @"Text in page 3"; } } I don't know why it doesn't work. Also if you have better way to do it, let me know. Thanks.
