  • Obtaining Nearby Wifi In C Using VS2010

    - by WizardsSleeve
    Hi All, I am trying to identify a method for obtaining nearby wifi access points using C in Windows. I am coding in Visual Studio 2010. I have read the necessary documentation but am lacking in guidance on how to implement code that would accomplish this. I am specifically interested in obtaining the MAC address of nearby access points or at a minimum the MAC address of the currently connected Wifi access point. Is it possible to do this using WMI in Windows, specifically on Windows XP SP3 and later? Any pointers on how to do this are greatly appreciated.

  • How to find out where my memory is going

    - by the_mandrill
    I've got the situation where the cycle of loading and then closing a document eats up a few Mb of RAM. This memory isn't being leaked as something owns it and cleans it up when the app exits (Visual Leak Detector and the Mac Leaks tool show agreement on this). However, I'd like to find out where it's going. I'm assuming it's some sort of cache in the application that gets populated when the document loads but not freed when the document is closed. Which methods or tools could I use to find out where these allocations are being made?

  • How to check if Contact has Image?

    - by Pentium10
    I am assigning to an ImageView contacts images using this code: mPhotoView = (ImageView) findViewById(R.id.photo); mPhotoView.setImageURI(objItem.getPhotoUri()); If the contact has no image, this does nothing, and no error is raised. When there is no image, I want to add a default image. So I need to check either if the image was added to the view, or check that the URI holds some image data How do I achieve that? Than I will set default image by this: mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);

  • Start all tab's activities for pre-cache

    - by Pentium10
    I have a TabActivity with three tabs defined. The first tab is light-weight and renders in acceptable time. But the 2nd and 3rd tab, does need a couple of seconds to get visually rendered, after I click them. I would like to launch them, after I've loaded my first tab, in background for pre-cache. Once they are loaded, I can switch quickly between them. So I am wondering how can I launch the 2nd and 3rd tab. They are intents loaded in the view area.

  • How can I pass information between 2 different View Controllers?

    - by sagiftw
    Hi, This is a simple question: I have 2 different view controllers, and each one has its own data stored in its .m file. I want to take a value, for instance, an integer value (int i=3;) that is declared in ViewController1 and pass it to ViewController2, so I will be able to use that value in the second view controller. Can anyone please tell me how to do it? Thanks in advance, Sagiftw

  • Recording app sound in iphone

    - by user292127
    Hi, I am developing a music mixing app in iphone. It'll mix the music and user can compose a new music from it. I need to record this final music. I had used AVAudiorecorder to record this one. But no change. It can record sound from microphone but I need to record app sound. I had used audio queue call back function to record the audio. But when app runs I can hear the audio from my app and I couldn't hear any sound from recorded audio. There is no problem with recording since I can hear the audio recorded through microphone. But I need an offline recorder which can record the audio output of iphone, rather than the audio input through microphone. I need a recorder which can record audio using ipod touch (no microphone). Any help?

  • Getting screen height before first display?

    - by Mark
    Hi, I have a ListView. I populate it with 8 items, that's all that fits vertically on the G1. Some of my users are saying the Droid has a taller screen height, and so I can probably add one or two more items to the ListView to take up the additional space provided. How could I measure the available height the screen offers at startup, before the UI is displayed? If I see the height can fit more than 8 items, I'd like to add one or two more rows, Thanks

  • iOS Display Different Image on Click

    - by user1506841
    Using XCode, I am trying to figure out how to display a different image when someone clicks or presses down on one of my buttons before being taken to a second screen. For example, I have a contact icon on my home screen. When a user clicks the icon, it should change to a darker version on tap before going to the contact screen. Any help is appreciated. -(IBAction) ButtonPressed :(id)sender { UIButton *tempButton = (UIButton *) sender; int tag = tempButton.tag; NSString *viewName; switch (tag) { case 1: [FlurryAnalytics logEvent:@"Contact-Screen"]; viewName = @"ContactScreen"; if( self.appDelegate.sound) [Click play]; [self.appDelegate moveToView:viewName]; break; } }

  • How to track how many times an iPhone app is opened?

    - by Jason
    I am building an iphone app and would like to keep track of how many times it has been opened so that I can prompt the user to do certain actions after it has been opened X number of times. I have thought about storing a variable in Core Data which I update every time it is opened, but this seems like a waste since it is a singleton data, not multiple instances of an object. What is the best way to store data like this and access it without slowing down the app opening time?

  • Collision detection on sub views contained in 2 separate parent UIViews?

    - by Chris
    Hi All, I originally setup some conditions using CGRectIntersectsRect for some collision detection which worked fine. In the greater scale of things I only need part of the view to be detected. So originally within the ViewController it was comparing 2 UIviews. Now what I need to do is collision detection of subViews within 2 different UIViews that are contained in a view in which the view controller does the logic. My script is no longer working as I suspect CGRectIntersectsRect only compares frames within the same view? I'll keep digging to confirm this. Any ways around this? Is it possible for example to get the x and y pos of the sub view in relation to the main view that's performing the logic?

  • Is it possible to embed C code in a C# project?

    - by Jonathan
    I know that it's possible to compile my C code into a dll, and then use P/Invoke to call that code. What I wondered if it was possible to have a chunk of C code embedded directly in my code, perhaps only available to one class... Something like this (non-working) example: public class MyClass { extern "C" { int do_something_in_c(int i) { return i*2; } } public int DoSomething(int value) { return do_something_in_c(value); } } I've been trying for a few hours using Visual Studio 2008, but I'm not getting anywhere, and I suspect that it isn't actually possible. Can anyone confirm or deny this? Thanks.
