Interrupt a thread in DatagramSocket.receive

- by SEK

I'm building an application that listens on both TCP and UDP, and I've run into some trouble with my shutdown mechanism. When I call Thread.interrupt() on each of the listening threads, the TCP thread is interrupted from listening, whereas the UDP listener isn't. To be specific, the TCP thread uses Socket.accept(), which simply returns (without actually connecting). Whereas the UDP thread uses DatagramSocket.receive, and doesn't exit that method. Is this an issue in my JRE, my OS, or should I just switch to (Datagram)Socket.close()?

.BAT Switches Parsing

- by giiYanJ

Erm.. I'm working with a switches parsing in BAT files, which goes like this: <commands> -a -b -x -y -z -u abc ...... The user may input a lot of switch, or none. So I used looped shift to make parsing infinite switches possible: :loop IF "%1"=="-a" ... SHIFT GOTO loop But when the script ends, I always get cmd executing the switches and showing up error like '-n' is not recognized as an internal... So, someone got any idea? Thanks a lot... P/S: Make solution sticks with BAT script if possible as using other language may cause dependencies problem as this script is aimed on ANY computer with Windows. Finally, thanks again =) EDIT: Tried shf301 suggestion, i found out that I used DEL %0 to delete itself but it seems the %0 is shifted into the arguments because of the SHIFT command.

Do you know any build systems with decent support for parallelization?

- by dahpgjgamgan

Hi, I am looking for a build system (working on ms windows) that has good support for parallelization of tasks/targets (or whatever you call them). To be more specific - during build (that is initiated on MS Windows machine) I need to copy source files to a number of different machines (which are not necessarily running Windows) and start a remote job on each of them - and I really like to do that on all machines at once. Does anyone know a build system that's capable of executing such a task in parallel. From what I googled, the options currently available are: -j switch in make - but i don't know if nmake supports this -some custom nAnt tasks -msbuild has some form of support for parallelization - seems similiar to make (meaning you don't specify what to do in parallel, just specify that it would be nice to build things that way) -fake (f# make) is written in functional programming language which are known to have good parallelization support - but I'm not very skillful in functional programming area. Any other solutions I could explore?

Arduino TimeSerial

- by user541597

I am working with the TimeSerial sketch (an example in the Arduino Time library). Everything works fine, and I can get it to output the time continuously. I am trying to set a switch which will read in a serial.read(). For example, I send 1 through the serial monitor, my sketch reads the one and runs a function I've created called resetfunc() which all it does is end serial and go back up to setup. It then asks me to enter the T and time stamp but doesn't wait and just keeps printing time. Why is it still doing this? When I haven't sent it the T and timestamp through serial yet?

c++: truth assignment warning with arguments?

- by John

I use the following to work with arguments in my programs, but it seems to just hand me a warning (just a warning): "warning: suggest parentheses around assignment used as truth value" The beginning of the code is as follows: enum{OPT_DISP_H = 0x2, OPT_DISP_W = 0x1}; int main(int argc, char *argv[]) { int opt = 0x00; char c; while((++argv)[0] && argv[0][0]=='-'){ while(c =* ++argv[0]) switch(c){ case 'h': opt |= OPT_DISP_H; break; //etc.. The while(c =* ++argv[0]) part being where the warning persists. The code works fine, but what does this warning mean opposed to what is used? I think the code is c = *++argv[0], using the pointer. So why does the single = work and what is really recommended to be used?

I have an Xcode static library project, how do I add a test target to it so I can run it there? (Ins

- by zekel

I want to be able to test library code in the library target so I don't have to switch over to a separate project to run it. I see how to add a target, but I'm not sure how to set it up to run like the "Command Line Tool" project template does. I tried adding a new "Shell Tool" target, but I don't know how to make it run like one. What build settings do I have to add to that target? What files (main.m?) do I need to start it up?

modifying constants in objective c during run time

- by moshikafya

I am trying to solve the following problem. I have the following constants in my header file: #define PREFS_MY_CONSTANT_1 @"bla1" #define PREFS_MY_CONSTANT_2 @"bla2" #define PREFS_MY_CONSTANT_3 @"bla3" ... In one of my functions, I'd like to print to the UIbutton one of those strings based on user input, so say the user inputs '1', i would show bla1. Instead of creating a huge switch (i have 100 of those), I am looking for a way to combine the constant with the variable holding the user input, so something like that ideally: NSInteger input; [button setTitle:PREFS_MY_CONSTANT_{$input} forState: UIControlStateNormal]; Is something like that possible? what would be the best way to solve this?

Database design to hold multiple iteration measurements

- by Valder

Hi All. I am new to sqlite and SQL in general. I am keen to switch from flat-files to sqlite for holding some measurement information. I need a tip on how to better layout the database, since I have zero experience with this. I have a ~10000 unique statistic counters that are collected before and after each test iteration. Max number of iterations are 10, though it could be less. I was thinking the following: CREATE TABLE stat_names(stat_id, stat_name); CREATE TABLE stats_per_iteration(stat_id, before_iter_1, after_iter_1, before_iter_2, after_iter_2, ...); stat_names table would hold mapping of a full counter to a uniq stat_id. stats_per_iteration table would hold mesurement data 1 + 10 * 2 columns. stat_names.stat_id = stats_per_iteration.stat_id OR maybe I should have a separate table for each iteration? Which would results in 1 + 10 tables in database. Thanks!

Does Anyone Still Prefer N-Tier Architecture After Having Shipped an MVC Application?

- by Jim G.

Other SO threads have asked people if they prefer N-Tier or MVC architecture. I'm not looking to continue that debate on this thread. I'm looking for something more specific. My Question: Does Anyone Still Prefer N-Tier Architecture After Having Shipped an MVC Application? Reason for My Question: Before I shipped an MVC web application, I wasn't convinced that it was superior to N-Tier Architecture. Specifically, if better unit testing was the only obvious benefit of MVC, then I saw no reason to switch gears and adopt a new architecture. But after having shipped an MVC application, I can see many benefits (which have been enumerated on other threads).

Deployment process

- by Balaji

We are having a massive system having around 15 servers hosting .Net WCF services, mvc application etc. When we do a deployment (out of office hours) we have to uninstall and install everything on the live servers. This takes lot of time and if something goes wrong we have to rollback everything. can you please suggest something different to this? like Deply into a other environment (whenever you like) and switch the URL to point to new servers [This comes with the overhead of cost of maintaining 2 copies of production (active and passive)] any other ideas please.

html - how do I make a page load in a new tab in IE8?

- by erynion

My website works in Firefox - pages on the site load in the current tab, and links off site load a new tab. IE8 won't behave: target="_blank" opens a whole new window; the other options, _self _top _parent, all open the page in the current tab. I have Firefox set to "Open new windows in a new tab." The links to pages on my site all have target="_self" and Firefox keeps these in the current tab. On the external links I don't have a target set (I added _blank to see if it fixed IE8, and doing that didn't affect Firefox). I can't find an equivalent setting in IE8. Tools-Internet Options-General-Tabs/Settings has an enable tabs box, and a sub-option to automatically switch to newly opened tabs. Is there some html that will work? An IE8 setting I'm missing? Any help appreciated.

OSGI bundle (or service)- how to register for a given time period?

- by Alec

Hello, all! Search did not give me a hint, how can i behave with the following situation: I'd love to have 2 OSGI implementations of the same interface: one is regular, the other should work (be active/present/whatever) on the given time period (f.e for Christmas weeks :)) The main goal is to call the same interface without specifying any flags/properties/without manual switching of ranking. Application should somehow switch implementation for this special period, doing another/regular job before and after :) I'm a newbie, maybe i do not completely understand OSGI concept somewhere, sorry for that of give me a hint or link, sorry for my English. Using Felix/Equinox with Apache Aries.

after dup2, stream still contains old contents?

- by BobTurbo

so if I do: dup2(0, backup); // backup stdin dup2(somefile, 0); // somefile has four lines of content fgets(...stdin); // consume one line fgets(....stdin); // consume two lines dup2(backup, 0); // switch stdin back to keyboard I am finding at this point.. stdin still contains the two lines I haven't consumed. Why is that? Because there is just one buffer no matter how many times you redirect? How do I get rid of the two lines left but still remember where I was in the somefile stream when I want to go back to it?

Facebook Connect in iPhone app: Able to have two sessions?

- by TheGambler

Does anyone know if you are able to have two sessions save in one iphone app? I don't mean two sessions active. I want to be able to let someone switch between facebook accounts in my app without having to logout and back in. To my understanding a sessions state is saved in user preferences and is resumed when you basically say [ session resume ]. What I'm wondering is if I can choose which session to resume based on the uid? If so then I can choose which session to resume. Thanks to all that reply.

Money type field returns Dollar, but regional set to UK (Windows 7)

- by Gareth

Hi, On a Windows 7 machine with Advantage Data Architect version 9.10.0.11, money type data is returned as Dollars, instead of Pounds. Sometimes, it will suddenly switch to Pounds, without me changing any settings. Everything else returns Pounds correctly (regional settings is UK with £ as the currency symbol). Has anyone else had this problem and/or found a solution? If I run any reports using the money data type field I can't be sure that it's going to be accurate. And no, I can't change the field type and handle the currency symbol myself. Any help would be appreciated.

toupper/tolower + locale (german)

- by Oops

Hi, how to convert a string (wstring) from lowercase to uppercase characters and vice versa? I searched the net and found there is a STL-function std::transform. But until now I hav'nt figured out how to give the right locale-object for example "Germany_german" to the function. Who can help please? my code looks like: wstring strin = L"ABCÄÖÜabcäöü"; wstring str = strin; locale loc( "Germany_german" ); // ??? how to apply this ??? std::transform( str.begin(), str.end(), str.begin(), (int(*)(int)tolower ); //result: "abcäöüabcäöü" The characters ÄÖÜ and äöü (it's like Ae, Oe, Ue) will not be converted correctly. P.S.: I don't prefer a big switch sweat and also I know BOOST is capable of everything, i would prefer a STL solution. thanks in advance Oops

using different string files in android

- by boreas

I'm porting my iPhone app to android and I'm having a problem with the string files now. The app is a translation tool and users can switch the languages, so all the localized strings are in both languages and they are independent from what locale the OS is running. For iOS version I have different files like de.strings, en.strings and fr.strings and so on. For every target with specified language pair I read the strings from the string tables, e.g. for de-fr I will include de.strings and fr.strings in project and set the name of the string tables in the info-list file and read strings from them. In the end I have one project containing different targets (with different info-list files) and all are well configured. I'm intending to do the same on android platform, but Is only one strings.xml allowed per project? How do I set different build target? How do I specify per target which strings.xml it should read?

How to pass an anonymous array of strings to a JavaScript function?

- by abatishchev

I want to pass to an array of controls' IDs to a javascript script function so it will switch control's enable state. For example, in C# it would be like this: func(false, new[] { "Control1", "Control2", "Control3" }); In that function I want to find corresponding controls and disable/enable them. For one control I do this next way: <script type="text/javascript" language="javascript"> function switchControls(value, arr) { for (var n = 0; n < array.length; n++) document.getElementById(n).disabled = value; } </script> <asp:CheckBox runat="server" onclick="switchControls(this.checked, [ '<%= Control1.ClientID %>', '<%= Control2.ClientID %>' ])" Text="Take?" /> How to implement this properly? Have I to use jQuery?

Exporting MS SQL Schema and Data

- by stringo0

I'm used to MySQL and PHPMyAdmin - I had to switch over to MSSQL for an ASP.net project, and I'm having tons of trouble. I'm using the express version of SQL 2008, with SQL Server Management Studio. The following are 2 questions I've been struggling with for a while: 1) How do I export the DB schema for the database? The table structure, etc.? 2) How do I export all the data in the database? Ideally I'd like to have a .sql file that can be run wherever I need the schema or data duplicated, for example a co-worker's computer for a shared project, or online when the project is being hosted. Thanks!

Best of both worlds: arrow keys for cursor movement or flipping through buffers.

- by dreeves

I really like this vim trick to use the left and right arrows to flip between buffers: "left/right arrows to switch buffers in normal mode map <right> :bn<cr> map <left> :bp<cr> (Put that in ~/.vimrc) But sometimes I'm munching on a sandwich or something when scrolling around a file and I really want the arrow keys to work normally. I think what would make most sense is for the arrow keys to have the above buffer-flipping functionality only if there are actually multiple buffers open. Is there a way to extend the above to accomplish that?
