  • Looking for recommnedation on JavaScript libraries in the leage of ExtJS and Qooxdoo for serious web

    - by Kabeer
    Hello. I'm looking for a JavaScript library for my web application. The application is very data intensive and has rich form controls (almost windows like). AJAX will be used liberally. The development platform is ASP.Net (mostly ASP.Net MVC will be used). I cannot pursue with ExtJs due to the price/license factor. I checked Qooxdoo but it is very windows-unfriendly. YIU fell short of my needs w.r.t. form controls it offers. Other libraries like jQuery do not offer rich form controls. So I am looking recommendations for a library that satisfies most of following needs: Rich UI controls Solid API for AJAX handling Employs good programming practices for scripting in frontend (preferably OO but not mandatory) Free. Else has only development cost and not production Windows friendly (or at least not unfriendly) Not monolithic. Should be independent (Not have development & production dependencies) Theme'ing should be easy (preferably wrapped by the library) I am not mentioning other basic needs (like browser compatibility). I hope any popular library will honor those.

  • What is a good program for storing "chunks" of commonly used source code

    - by Rob Wiley
    I've looked at CodeLocker (poorly styled and relatively unflexible, but free) and Source Code Library (Overzone software - very nicely styled, looks flexible, but very expensive - $80). Ideally, I'm looking for a relatively simple, inexpensive program (not an online website) that I can save text data (source code) with a title and keywords, maybe even a description. It would also have some type of search functionality.

  • Android: How to restore List data when pressing the "back" button?

    - by Rob
    Hi there, My question is about restoring complex activity related data when coming back to the activity using the "back" button". Activity A has a ListView which is connected to ArrayAdapter serving as its data source - this happens in onCreate(). By default, if I move to activity B and press "back" to get back to activity A, does my list stay intact with all the data or do I just get visual "copy" of the screen but the data is lost? What can I do when more than activities are involved? Let's say activity A starts activity B which starts activity C and then I press "back" twice to get to A. How do I ensure the integrity of the A's data when it gets back to the foreground? PrefsManager does not seem to handle complex object very intuitively. Thanks, Rob

  • How to get video file details eg. duration in Android?

    - by spirytus
    I struggle to get specific video file details so duration etc. from the file the files recorded earlier. All I can currently do is to get cursor with all the files, then loop one by one. Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), MediaStore.Video.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); if(cursor.moveToFirst()) while(!cursor.isLast()){ if(cursor.getString(3)==fight.filename) { // do something here } cursor.moveToNext(); } I need however to access details of specific files so I tried to create URI but no luck as cursor returned is always null. Where do I go wrong? Uri uri = Uri.parse(Environment.DIRECTORY_DCIM+"/FightAll_BJJ_Scoring/"+(fight.filename)); Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), uri, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); // cursor is always null here

  • Creating/Maintaining a large project-agnostic code library

    - by bufferz
    In order to reduce repetition and streamline testing/debugging, I'm trying to find the best way to develop a group of libraries that many projects can utilize. I'd like to keep individual executable relatively small, and have shared libraries for math, database, collections, graphics, etc. that were previously scattered among several projects and in many cases duplicated (bad!). This library is to be in an SVN repo and several programmers will be working on it. This library will be in constant development along with the executables that utilize it. For example, I want a code file in ProjectA to look something like the following: using MyCompany.Math.2D; //static 2D math methods using MyCompany.Math.3D; //static #D math methods using MyCompany.Comms.SQL; //static methods for doing simple SQLDB I/O using MyCompany.Graphics.BitmapOperations; //static methods that play with bitmaps So in my ProjectA solution file in VisualStudio, in order to develop/debug the MyCompany library I have to add several projects (Math, Comms, Graphics). Things get pretty cluttered and Solution files get out of date quickly between programmer SVN commits. I'm just looking for a high level approach to maintaining a large, shared code base in an SCN repository. I am fully willing to radically redesign my approach. I'm looking for that warm fuzzy feeling you get when you're design approach is spot on and development is fluid and natural. And ideas? Thanks!!

  • How do I iterate through the id properties of R.java in android?

    - by mgpyone
    I've 16 textViews and need to set something like this done: for (int i=1; i<6; i++) { int $RidInt = R.id.s; tv[i] = (TextView)findViewById($RidInt); tv[i].setTypeface(face); tv[i].setClickable(true); tv[i].setOnClickListener(clickListener); } my R.java file is : public final class R { public static final class attr { } public static final class drawable { public static final int icon=0x7f020000; } public static final class id { public static final int s1=0x7f050000; public static final int s10=0x7f050009; public static final int s11=0x7f05000a; public static final int s12=0x7f05000b; public static final int s13=0x7f05000c; public static final int s14=0x7f05000d; public static final int s15=0x7f05000e; public static final int s16=0x7f05000f; public static final int s2=0x7f050001; public static final int s3=0x7f050002; public static final int s4=0x7f050003; public static final int s5=0x7f050004; public static final int s6=0x7f050005; public static final int s7=0x7f050006; public static final int s8=0x7f050007; public static final int s9=0x7f050008; } public static final class layout { public static final int main=0x7f030000; public static final int toast=0x7f030001; } public static final class string { public static final int app_name=0x7f040000; public static final int s2=0x7f040001; } }

  • What is the best way to get an audio file duration in Android?

    - by Gilead
    Hi! I'm using a SoundPool [ 1 ] to play audio clips in my app. All is fine but I need to know when the clip playback has finished. At the moment I track it in my app by obtaining the duration of each clip using a MediaPlayer [ 2 ] instance. That works fine but it looks wasteful to load each file twice, just to get the duration. I could roughly calculate the duration myself knowing the length of the file (available from the AssetFileDescriptor [ 3 ]) but I'd still need to know the sample rate and the number of channels. I see two potential solutions to that problem: Figuring out when a clip has finished playing (doesn't seem to be possible with SoundClip). Having a class which could load just the header of an audio file and give me the sample rate/number of channels (and, ideally, the sample count to get the exact duration). Any suggestions? Thanks, Max The code I'm using at the moment (works fine but is rather heavy for the purpose): String[] fileNames = ... MediaPlayer mp = new MediaPlayer(); for (String fileName : fileNames) { AssetFileDescriptor d = context.getAssets().openFd(fileName); mp.reset(); mp.setDataSource(d.getFileDescriptor(), d.getStartOffset(), d.getLength()); mp.prepare(); int duration = mp.getDuration(); // ... } On a side note, this question has already been asked [ 4 ] but got no answers.

  • How to use a ListView and a ViewFlipper to navigate user in an Android app?

    - by virsir
    I want to set up some menu-like navigator for my app. There is a listView in the main page and it contains two items, click each one will show its child view with ViewFlipper, and if user clicked the back button, he will return to the homepage again. The question is how to make it, I can only use ViewFlipper to flip to next screen or prev screen, how to manage these child views here? How to put them in my layout xml file?

  • How to cache and store objects and set an expire policy in android?

    - by virsir
    I have an app fetch data from internet, for better performance and bandwidth, I need to implement a cache layer. There are two different data coming from the internet, one is changing every one hour and another one does not change basically. So for the first type of data, I need to implement an expire policy to make it self deleted after it was created for 1 hour, and when user request that data, I will check the storage first and then goto internet if nothing found. I thought about using a SharedPrefrence or SQLDatabase to store the json data or serialized object string. My question is: 1) What should I use, SharedPrefrence or SQLDatabase or anything else, a piece of data is not big but there are maybe many instances of that data. 2) How to implement that expire system.

  • How can I prevent my Android app/service from being "killed" from a task manager?

    - by Don
    It is very important that my service stay running until someone with a password stops the service from my UI screen. My app runs great but it is designed to be turned on/off by parents (with a password) on their kids phones. I have managed to make everything work but the problem I'm having is that if the kid uses a task manager to kill my service then my app is useless. I would be grateful to anyone who knows a way to either 1) monitor the service and start it back up automatically if its "killed" or 2) prevent someone from being able to kill it except from the activity (administration screen) that launched the service. Or both? I'm sorry if I'm not very clear in describing the problem, I'm a beginner. I've made great progress so far but I am stuck at this last hurdle.

  • iPhone static library Clang/LLVM error: non_lazy_symbol_pointers

    - by Bekenn
    After several hours of experimentation, I've managed to reduce the problem to the following example (C++): extern "C" void foo(); struct test { ~test() { } }; void doTest() { test t; // 1 foo(); // 2 } This is being compiled for iOS devices in XCode 4.2, using the provided Clang compiler (Apple LLVM compiler 3.0) and the iOS 5.0 SDK. The project is configured as a Cocoa Touch Static Library, and "Enable Linking With Shared Libraries" is set to No because I'm building an AIR native extension. The function foo is defined in another external library. (In my actual project, this would be any of the C API functions defined by Adobe for use in AIR native extensions.) When attempting to compile this code, I get back the error: FATAL:incompatible feature used: section type non_lazy_symbol_pointers (must specify "-dynamic" to be used) clang: error: assembler command failed with exit code 1 (use -v to see invocation) The error goes away if I comment out either of the lines marked 1 or 2 above, or if I change the build setting "Enable Linking With Shared Libraries" to Yes. (However, if I change the build setting, then I get multiple ld warning: unexpected srelocation type 9 warnings when linking the library into the final project, and the application crashes when running on the device.) The build error also goes away if I remove the destructor from test. So: Is this a bug in Clang? Am I missing some all-important and undocumented build setting? The interaction between an externally-provided function and a struct with a destructor is very peculiar, to say the least.

  • iPhone/Android: How to Send Keystrokes To Laptop Over Wifi?

    - by Cirrostratus
    How can I best implement a system for send keystrokes/commands via an iPhone and/or Droid to a desktop or laptop computer via WiFi or bluetooth? There are apps for VLC, Keynote and other applications that do this, so I know it's possible but don't know what technology base to use. The implementation is probably different on Windows and OS X, but if they could be similar that'd be a big win. If VNC-type technology is used, that'd be fine but I only need to send key commands and mouse clicks—I don't need to be able to navigate the screen space.

    - by kimera84
    Hi Everyone, I'm new in blackberry environement programming, I'm developing an application for this device and there are some probs about libraries that I don't understand. I have the main project called: npoBBerry - his library is NET_RIM_BLACKBERRY (from 4.6.1 version...) it includes other two projects: Npo - his library is standard jre6 (Npo inlcudes NpoCore) NpoCore - his library is standard jre6 Compliance was set... In Java Compiler level is set to 1.4 for all. Now the problem is that I'm not able to build my project. 4 errors: Error preverifying class ch.yek.npo.model.Advertising Error preverifying class ch.yek.npo.repository.Repository$1 Error!: Error: preverifier failed: C:\Program Files\eclipse\plugins\net.rim.eide.componentpack4.6.1_4.6.1.27\components\bin\preverify.ex ... Error!: Error: preverifier failed: C:\Program Files\eclipse\plugins\net.rim.eide.componentpack4.6.1_4.6.1.27\components\bin\preverify.ex ... I know that libraries are differents but maybe I'm missing something. NpoCore represents models, interfaces Npo just take data from a repository NpoBBeryy just use this data from Services... Please help and thanks in advance... :)

  • Android - how update widget often but only when it is visible?

    - by tomash
    I'm going to create widget which needs to update its content every minute (it shows time-related data). However, there is no need to update widget if it is currently invisible, which means: screen is turned off another app is running widget is placed on another (invisible) home screen tab What is the best way to update only visible widget every minute - without waking up device nor doing unnecessary computations? After widget becomes visible, small lag before update is acceptable.

  • GCC Dynamic library building problem

    - by Sirish Kumar
    I am new to linux, while compiling with dynamic library I am getting the segmentationfault error. I have two files ctest1.c void ctest1(int *i) { *i =10; } ctest2.c void ctest2(int *i) { *i =20; } I have compiled both files to a shared library named libtest.so using following command gcc -shared -W1,-soname,libtest.so.1 -o libtest.so.1.0.1 ctest1.o ctest2.o -lc And I have wrote another program prog.c which uses functions exported by this library prog.c #include void (ctest1)(int); void (ctest2)(int*); int main() { int a; ctest1(&a); printf("%d",a); return 0; } And when I have built the executable with following command gcc -Wall prog.c -L. -o prog But when I run the generated executable I get the SegmentationFault error. When I checked the header of prog with ldd it shows linux-vdso.so.1 = (0x00007f99dff000) libc.so.6 = /lib64/libc.so.6 (0x0007feeaa8c1000) /lib64/ld-linux-x86-64.so.2 (0x00007feeaac1c000) Can somebody tell what is the problem

  • [Java/Android] Multidimensional array to ListView.. how?

    - by Yverman
    I have a query result set which I like to edit first and then put it to my ListView. Without editing my data first, I could use SimpleCursorAdapter like that: ListAdapter adapter = new SimpleCursorAdapter( this, R.layout.list_item, mCursor, new String[] { "address", "city" }, new int[] { R.id.address, R.id.zip_city }); this.setListAdapter(adapter); But now, I put everything in a multidimensional array like that: if(mCursor.isFirst()) { //create a new array String[][] listData = new String[mCursor.getCount()][3]; int i = 0; do { listData[i] = new String[] { mCursor.getString(mCursor.getColumnIndex("address")), mCursor.getString(mCursor.getColumnIndex("zip")) + " " + mCursor.getString(mCursor.getColumnIndex("city")), calculateDistance(Double.parseDouble(mCursor.getString(mCursor.getColumnIndex("diff")))) }; i++; } while(mCursor.moveToNext()); } So my problem is now, I have no idea how to put this to my ListView. Could someone help me here? Sorry for my bad english and Java knowledge. :)
