  • Use one single DLL library to import other libraries at runtime

    - by Yifan
    I am writing a Win32 DLL library that can be redistributed. I am using different versions of the windows API because I want to support Windows 7 functions, but still have support for Windows 2000 (with some function disabled). What I have currently is MyLib2000.dll, MyLibXP.dll, and MyLibVista.dll, and my application chooses which library to load at runtime. I want a way to have a single DLL (MyLib.dll) that stores the other three in itself and when it's being loaded, it extracts the correct DLL out of itself and loads it. I know this is not the best way to do this, so suggestions on another method of doing this is welcome.

  • MPMoviePlayerContentPreloadDidFinishNotification seems more reliable than MPMoviePlayerLoadStateDidChangeNotification

    - by user567889
    I am streaming small movies (1-3MB) off my website into my app. I have a slicehost webserver, I think it's a "500MB slice". Not sure off the top of my head how this translates to bandwidth, but I can figure that out later. My experience with MPMoviePlayerLoadStateDidChangeNotification is not very good. I get much more reliable results with the old MPMoviePlayerContentPreloadDidFinishNotification If I get a MPMoviePlayerContentPreloadDidFinishNotification, the movie will play without stuttering, but if I use MPMoviePlayerLoadStateDidChangeNotification, the movie frequently stalls. I'm not sure which load state to check for: enum { MPMovieLoadStateUnknown = 0, MPMovieLoadStatePlayable = 1 << 0, MPMovieLoadStatePlaythroughOK = 1 << 1, MPMovieLoadStateStalled = 1 << 2, }; MPMovieLoadStatePlaythroughOK seems to be what I want (based on the description in the documentation): MPMovieLoadStatePlaythroughOK Enough data has been buffered for playback to continue uninterrupted. Available in iOS 3.2 and later. but that load state NEVER gets set to this in my app. Am I missing something? Is there a better way to do this?

  • Load large images into Bitmap?

    - by GuyNoir
    I'm trying to make a basic application that displays an image from the camera, but I when I try to load the .jpg in from the sdcard with BitmapFactory.decodeFile, it returns null. It doesn't give an out of memory error which I find strange, but the exact same code works fine on smaller images. How does the generic gallery display huge pictures from the camera with so little memory?

  • How do you create a writable copy of a sqlite database that is included in your iPhone Xcode project

    - by Iggy
    copy it over to your documents directory when the app starts. Assuming that your sqlite db is in your project, you can use the below code to copy your database to your documents directory. We are also assuming that your database is called mydb.sqlite. //copy the database to documents NSFileManager *fileManager = [NSFileManager defaultManager]; NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"mydb.sqlite"]; if(![fileManager fileExistsAtPath:path]) { NSData *data = [NSData dataWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/mydb.sqlite"]]; [data writeToFile:path atomically:YES]; } Anyone know of a better way to do this. This seems to work ...

  • "out of scope" error when iterating an NSMutableArray

    - by wgpubs
    Why am I getting an "out of scope" error whenever I try to access the "url" variable in this loop? for(NSString *url in self.winnerImageURLs) { [mediaItemString appendFormat:@"{\"type\":\"image\",\"src\":\"%@\",\"href\":\"%@\"},", url, url]; } The class of very item in the "self.winnerImageURLs" NSMutableArray comes back as NSCFString so I'm not sure what the dealio is here. Any ideas on what I'm doing wrong??? Thanks

  • How to read an image from disk and block until its read?

    - by Shizam
    I'm loading 5 images from disk but I want the 1st image I read to show as soon as possible. Right now I do UIImage *img = [UIImage imageWithContentsOfFile:path]; in a for loop but since imageWithContentsOfFile:path isn't blocking all 5 images wind up getting read from disk before the first one will appear (because they're all using up I/O). I confirmed this by just load one and it appeared on screen faster than if I load all 5. I'd like to load the 1st image and block until its fully read and shown before loading the next 4 or load the 1st one and be notified when its done before loading the next 4 but I can't figure out a way to do it. None of the 'WithContentsOfFile' methods for data or image block and they don't notify or have delegate methods. Any suggestions? Thanks

  • Suddenly Facebook API stopped working on Windows Phone

    - by Juan Diego
    My code hasn't changed, it was working yesterday or so. I can oauth, get the token but then doing the following: WebClient wc = new WebClient(); wc.DownloadStringCompleted += result; wc.DownloadStringAsync(new Uri("https://graph.facebook.com/me&access_token=xxxTOKENxxx", UriKind.Absolute)); Returns a NotFound WebClient exception: "The remote server returned an error: NotFound." Strange thing is that when pasting that same url on Chrome or IE it does work(PC). Tried on Emulator and on 2 different real WP devices, even pasting the same url on the WP browser. Feels like facebook is rejecting Windows Phone for some reason? Anyone has an idea of what might be happening?

  • Activity should be transparent, but has black background

    - by Uwe Krass
    I followed the instructions of writing a transparent layout. My res/values/style.xml looks like this: <resources> <style name="Theme" parent="android:Theme" /> <style name="Theme.Transparent"> <item name="android:windowBackground">@drawable/transparent_background</item> </style> <drawable name="transparent_background">#00000000</drawable> </resources> The activity snippet looks like this: <activity android:name=".Controlls" android:label="Controlls" android:theme="@style/Theme.Transparent"> When I start this activity from my root activity, the layout gets drawn correctly, but the background stays black.

  • suppress keyboard in iphone UiWebViews

    - by rob
    I have an app that uses UiWebViews, and I need to not show the keyboard for a text field within such a view. I provide my own buttons that insert the limited sorts of text the field allows, but I also need to allow pasting (I will filter what gets pasted) and adjusting the cursor position. Any way to do this?

  • Twitter and Facebook on iPhone - save sessions across app launches?

    - by lostInTransit
    Hi I am using OAuth for twitter and fb-connect for facebook authentication in my iPhone app. Is it possible to save the user sessions across app launches? i.e. if the user logs in once, the next time they launch the app, we log them in automatically from some state saved the last time the app closed? For Twitter would it work if I just save the auth_token and use it every time the user wants to use twitter from my app? Or do I need to do anything else? I could not get it to work like that so wondering if I was doing something wrong. Thanks.

  • How should open source libraries be used on Windows?

    - by Jason Owen
    There are many open-source libraries that can be compiled with Visual Studio. I'm porting a program from Linux to Windows, but it depends on a number of libraries. I don't know what the best practices regarding libraries are on Windows. On Linux, these libraries are typically part of the distribution. To use sqlite on Debian, for example, you need only to install libsqlite3-dev and the include files and libraries (both static and dynamic) are automatically installed and available to your program. If you need a different version than your distribution supplies, you can compile it in your home directory, install it to ~/include and ~/lib, and set the appropriate environment variables so that your compiler includes those directories in its search path. What is the best way to use libraries that are distributed as source on Windows? If I link dynamically rather than statically, is there an easy way to copy required DLLs into the output directory to ease redistribution (assuming license requirements are met)?

  • iPhone Application: force landscape mode, strange behaviour...?

    - by David Lawson
    This is a method I use to switch display views, based on a string passed (for example you could pass MainMenuViewController to switch views to a new instance of that class): - (void)displayView:(NSString *)newView { NSLog(@"%@", newView); [[currentView view] removeFromSuperview]; [currentView release]; UIViewController *newView = [[NSClassFromString(newView) alloc] init]; [[newView view] setFrame:CGRectMake(0, 0, 320, 460)]; [self setCurrentView:newView]; [[self view] addSubview:[currentView view]]; } I have my application forced into landscape view (.plist and -shouldRotate), but if you look in the code: [[newView view] setFrame:CGRectMake(0, 0, 320, 460)]; I have to set the frame of the newView to a portrait frame for the view to be displayed correctly - otherwise, for example, a button on the new view can only be pressed in certain parts of the screen (rectangle up the top), unresponsive anywhere else. Even though in all my NIB files they are set to landscape.

  • Android - Debugging on device

    - by teepusink
    Hi, How do I install the app that I'm making on an actual device? I'm on Mac Snow Leopard with a Nexus One phone and I've followed the steps here http://developer.android.com/intl/zh-TW/guide/developing/device.html So I added: 1. android:debuggable="true" 2. Turn on "USB Debugging" on your device. However, when I go to the terminal and do "adb devices" only the emulator shows up there. I'm supposed to see my device name too right? What am I missing? Thanks, Tee
