• Android canceling all alarm set

  - by spagi

  Hi all. I am making an event application and user can set a reminder for events he wants. So i use the alarmManager to create alarms. I would like to put a cancel all option to my main activity so that i could cancel all the alarms created by my application. The usual method for canceling the alarm with the same intent doesnt really help cause i set tha alarms on a different activity than the one I want to cancel them in. So is there a way to cancel all the alarms created by my application? Thanks!

• Dynamic, reflective SignalHandler in Java

  - by pilcrow

  How do I install signal handling logic iff sun.misc.Signal is available? Background First generation of my code looked something like this: class MyApp { public static void main(String[] args) { ... Signal.handle(term_sig, new SignalHandler() { public void handle(Signal sig) { ... } }); ... } } I believe I understand how to reflectively test for and use signal handlers -- Class.forName("sun.misc.Signal"), reflectively call Signal.handle, and so forth. My impulse was simply to instantiate another anonymous inner class with the dynamically obtained SignalHandler class, but I think that's just wishful syntax.

• Where can I find a control similar to the Firefox Rich List Box for use in my application?

  - by bsruth

  I'm trying to implement a control similar to Firefox's Rich List Box: However, I can only find the XUL implementation of this control, and I don't want to have to include a XUL processing engine in my application just to get a cool looking listbox. I've been trying to implement one on my own by customizing MFC's CListBox control, but am starting to realize it may take more time than I had intended. Before continuing to implement this control from scratch, I was wondering if anyone knew of a similar control that already exists, either commercial or open source. The main functionality I would like to have is: Small display for non selected items that expands when selected. Ability to add arbitrary controls to the expanded view. Preferably native code, but can probably use managed controls via native/managed interop with out too much extra work. Any help would be appreciated, I don't want to have to reinvent the wheel if I don't have to.

• Why this C program outputs a negative number?

  - by JMSA

  I have assigned the complement value in an unsigned variable. Then why this C program outputs a negative number? #include<stdio.h> #include<conio.h> int main() { unsigned int Value = 4; /* 4 = 0000 0000 0000 0100 */ unsigned int result = 0; result = ~ Value; /* -5 = 1111 1111 1111 1011 */ printf("result = %d", result); /* -5 */ getch(); return 0; }

• Windows Mobile application icon

  - by Andy White

  Is it possible to specify the application icon for a windows mobile app from a resource file or other configuration besides the .csproj? The reason I would like to do this is because I have an application that can be configured to run in several different ways. We would like to build out three unique .cabs based on these configurations, and we would like to use a different icon for each version. One option we've considered is just running multiple builds and swapping out the icon file each time, but we were hoping there would be a way to do this using a "resource" DLL or something along those lines, that could be compiled or linked in to the main .exe.

• XCode - Multiple targets, Multiple *internationalized* names?

  - by Kris Jenkins

  I've got an internationalized iPhone project. In the various ${lang}.lproj/InfoPlist.strings files I've got a single key, CFBundleName = "My App Name". That's working fine for a single target, but I can't make it work for multiple targets. I'd like to have several translated InfoPlistMyApp.strings files for the main target, plus several InfoPlistMyApp*Lite*.strings files for the lite version. But I can't figure out how to set it up. The InfoPlist.strings name seems to be set in stone, so I can't replace it dynamically. Any ideas?

• Can an application's Service ever run in a different process?

  - by kpdvx

  If an application begins a Service via bindService or startService, will this Service object ever run from a process different from that of the application? I ask because many Android example projects begin a service and communicate to them using IPC which seems wholly unnecessary considering that, according to the Android Service documentation, "... services, like other application objects, run in the main thread of their hosting process." IPC, AIDL, and the IBinder interface only seem useful if connecting to a Service started by an application other than your own. Is this a correct or fair understanding?

• Read XML from an XDocument with silverlight

  - by user625310

  Hi I have managed to load an XDocument with xml data from this link http://go.yr.no/go/e/main/http://www.yr.no/place/Norway/Telemark/Sauherad/Gvarv/forecast.xml. I am using C# and .Net in Blend and producing a web app (ie some of the normal .Net functions is not included in the silverlight plugin). I have researched this a lot but can not figure out: how to put the "text" in the link node in a string variable and how to all put the "-11" from ? in a array and link it to the "time from"? I think i have to use LINQ, but the stuff on MSDN and other tutorials is confusing and to general. huge thank in advance Regards Arnt I am sorry to ask such novice questions, but i have searched a lot. Also please excuse the typos, English is not my first language. Huge thank in advance Arnt

• Which video format(s) should a webapp serve?

  - by NoozNooz42

  I need to put up a few videos on a Webapp and I'm a bit lost. My requirements are: DRM is not a concern at all it should work on the iPhone (and iPad) and on the main browsers (Safari, Internet Explorer, Firefox, Opera). it is not a problem at all if the video doesn't play on Linux (because it's a video/screencast of a Windows/OS X software targetted at, well, Windows and OS X users) it is not a problem at all if it also works on Linux (I'm a Linux user myself) Can a unique format be served (like H.264) and play without any additional work on my part or do I need to convert the videos to different formats and have the webapp serve different video formats depending on the browser used? Should I use the "video" tag of HTML5 when I detect an HTML5 capable browser? What's the "safest" bet here? I take it that Flash is out of the equation seen that iPhone/iPad is a requirement.

• printing double in binary

  - by Happy Mittal

  In Thinking in C++ by Bruce eckel, there is a program given to print a double value in binary.(Chapter 3, page no. 189) int main(int argc, char* argv[]) { if(argc != 2) { cout << "Must provide a number" << endl; exit(1); } double d = atof(argv[1]); unsigned char* cp = reinterpret_cast<unsigned char*>(&d); for(int i = sizeof(double); i > 0 ; i -= 2) { printBinary(cp[i-1]); printBinary(cp[i]); } } Here while printing cp[i] when i=8(assuming double is of 8 bytes), wouldn't it be undefined behaviour? I mean this code doesn't work as it doesn't print cp[0].

• Rendering XHTML as MS Word Document - Headers

  - by Paul

  Hi, I generate an XHTML document and set the Mime type as "application/msword" so it opens in Word. To create a header I appear to have to reference an external file thus: <style> ... @page{mso-footnote-separator:url("**OUT_files/header.htm**") fs; mso-footnote-continuation-separator:url("OUT_files/header.htm") fcs; mso-endnote-separator:url("OUT_files/header.htm") es; mso-endnote-continuation-separator:url("OUT_files/header.htm") ecs;} @page Section1{ mso-header-margin:.5in; mso-header:url("OUT_files/header.htm") h1; } } ... </style> Does anyone know how to reference a div defined within the main XHTML document itself, without having to reference an external file? Thanks

• VB.NET: SQLite to MSSQL

  - by user1736785

  I have a vb.net project that uses a SQLite database. I do this by using dataset/table adapters. The client is happy and all works well. However I have just heard that they plan on providing this product to another customer that wishes to use their MSSQL database. So I am writing this post so I can mentally prepare for this before I begin. I am not a database pro and have really enjoyed the simplicity of setting up and managing an SQLite database. So any ideas on the easiest way to support MSSQL as well? I am happy to run them parallel to each other. Can I just make a separate service / middleware that syncs the SQLite database to the MSSQL on a timer and does not care about what the main app is up to? Any pointers are appreciated.

• How to record when user follows external links without slowing user down

  - by taw

  I want to track when user clicks external links for analytics purposes. The simplest solution is to replace all external links with links to special record-and-redirect controller, but that would slow the user unnecessarily. The second idea would be to override click event and within in $.post a message to record controller, then let the main event handler happen, which will usually be either click (open link in same tab) or middle click (open in new tab) - good either way, and the user won't have to wait for wait for my server to record it, it's fire-and-forget. (I don't care if users without Javascript don't get tracked) Is that a reasonable way to go? Or what else would be the best way to track all external link clicks?

• Local Live Quicktime Video Broadcast, latency?

  - by Snowwire

  I'm looking into the feasibility of using a local server to distribute live video of a conference to delegates in the same room. They would still hear the live audio coming from the speaker, so only the video would be streamed. I was considering a Darwin Steaming Server (a lot of iPhone users to support) and encoding with H.264. My main concern is latency across the network. Even with everything running locally, would there be lip sync issues between the live audio and the 'live' video stream? It feels like there will be problems given the encoding, broadcasting, decoding to be completed, but I've never done any like this before so thought I would check. Thanks

• how to Calculate number of address bits needed for memory?

  - by leon

  Hi I am preparing my exam for computer system. I don't quite understand how to calculate the number of address bits needed for the memory. For example, Suppose that a 1G x 32-bit main memory is built using 256M x 4-bit RAM chips and this memory is word-addressable. What is the number of address bits needed for a memory module? What is the number of address bits needed for the full memory? And what about If the memory is byte addressable, what would be the solutions? Many thanks

• Does preloading content from a page skew my google analytics stats?

  - by user278457

  I'd like to write myself a simple script that uses AJAX to load the content from each page on my main navbar into a hidden div on the current page. This is just so that I can preload as much of my important content as possible and get it cached on the user's computer (hopefully) before they've finished with the current page and want to move on. I'm concerned that doing a request for every page on the site, every time someone visits, will really ruin the validity of my google analytics stats. How does AJAX interact with google analytics? Does it count as a "page visit"?

• Do you know of a good program for editing/translating resource (.rc) files?

  - by djeidot

  I'm building a C++/MFC program in a multilingual environment. I have one main (national) language and three international languages. Every time I add a feature to the program I have to keep the international languages up-to-date with the national one. The resource editor in Visual Studio is not very helpful because I frequently end up leaving a string, dialog box, etc., untranslated. I wonder if you guys know of a program that can edit resource (.rc) files and Build a file that includes only the strings to be translated and their respective IDs and accepts the same (or similar) file in another language (this would be helpful since usually the translation is done by someone else), or Handle the translations itself, allowing to view the same string in different languages at the same time.
