• Datatable -filter records with linq based on some internal index

  - by Karan

  Hello Guys, I have a datatable with plenty of records. And i have a range like lowerRange = 10 and upperRange = 200. I want the pull the records starting at row 10 till row 200. Now i don't want to add any new index based column into the datatable. Is there any way with the help of linq, i can pull the set of rows based on some internal datatable index? I guess, the datatable must be maintaining some row index implicitly. Please suggest.

• How to I preload images where it actually forces the images to load before continuing (html/javascri

  - by Mr. Flibble

  I want to preload images but ensure they are loaded before continuing. How can I do this? The following does not work as it sends off the load request only, but doesn't wait till the image is loaded. So it is possible that the image isn't loaded when requested soon after. jQuery.preloadImages = function () { for (var i = 0; i < arguments.length; i++) { jQuery("<img>").attr("src", arguments[i]); } } $.preloadImages("img1.jpg","img2.jpg");

• Is there anything wrong with taking immediate actions in constructors?

  - by pestaa

  I have classes like this one: class SomeObject { public function __construct($param1, $param2) { $this->process($param1, $param2); } ... } So I can instantly "call" it as some sort of global function just like new SomeObject($arg1, $arg2); which has the benefits of staying concise, being easy to understand, but might break unwritten rules of semantics by not waiting till a method is called. Should I continue to feel bad because of a bad practice, or there's really nothing to worry about? Clarification: I do want an instance of the class. I do use internal methods of the class only. I initialize the object in the constructor, but call the "important" action-taker methods too. I am selfish in the light of these sentences.

• Suspend TimerTask until the next execution

  - by user1052518

  I am using a TimerTask to run some periodic tasks, the task being processing a set of files. I have a requirement where if the number of files to be processed exceeds a pre-determined limit, the thread suspends execution and waits till the next cycle to start processing the files again. Is there a way to suspend the TimerTask until the next execution period or do I have to extend the TimerTask class to achieve this functionality? I saw there is a TimerTask.cancel method, but this will cancel all further executions of this thread. I don't want this to happen. I just want the thread to be suspended until the next execution period. I don't have the luxury of moving to any of the other concurrent classes in Java as our framework uses TimerTask, and I have to stick with it. Any suggestions, pointers or tips are greatly appreciated. thanks, Asha

• Cross domain XMLHttpRequest in classic ASP

  - by HahaHehe

  My code is working fine till i migrate it to another server with firewall. After since, some part of my code is not working. Its seem to be the xmlhttp POST problem. Can someone point me to the right direction and how to determine if the firewall is the problem. My client insisted to me to use classic asp, so i cannot upgrade to .net. Dim objHttp SUBMIT_URL = "http://www.abc.com/confirm.asp" Call Process() Public Sub Process() set objHttp = Server.CreateObject("Microsoft.XMLHTTP") 'set the timeout values in milliseconds lResolve = 1 * 1000 lConnect = 1 * 1000 lSend = 2 * 1000 lReceive = 2 * 1000 objHttp.open "POST", SUBMIT_URL, false objHttp.setRequestHeader "Content-type", "application/x-www-form-urlencoded" objHttp.Send str if err.number <> 0 then Response.Write "Error : " & err.Description err.Clear end if End Sub

• linux cpu usage

  - by davidbobo

  I am working on unix. I want to knwo the current cpu usage of a process. I understood that ps give the average of cpu used till the process is up - it is not the current usage. Is there a way to print only the cpu from the top command without 10 more parameters and headers? I know how to do it with awk - this is not the way i want to do it. top -p 20705 -bc -n 1 | tail -n 2 | awk '{ print $9}' | head -n 1 If there is another simple way to do it, not reading /proc/stat... If there is a simple way doing it from c++, it is also ok.

• Regex to match a Java method signature

  - by nitesh

  I am having this particular requirement where a method has to be identified by different regular expressions for different components. For example, there need to be a regex for return parameter, one for method name, one for argument type and one for argument name. I was able to come up with an expression till this step as follows - ([^,]+) ([^,]+)\((([^,]+) ([^,]+))\) It works well for a method signature like - ReturnType foo(Arg parameter) The regular expression identifies ReturnType, foo, Arg and parameter separately. Now the problem is that a method can have no/one/multiple arguments separated by commas. I am not able to get a repeating expression for this. Help will be appreciated.

• How to debug lost events posted from non-GUI thread in Qt?

  - by gp

  As the subject says, I'm posting events from non-GUI thread (some GStreamer thread, to be precise). Code looks like this: GstBusSyncReply on_bus_message(GstBus* bus, GstMessage* message, gpointer data) { bool ret = QMetaObject::invokeMethod(static_cast<QObject*>(data), "stateChanged", Qt::QueuedConnection); Q_ASSERT(ret); return GST_BUS_PASS; } The problem is, stateChanged (doesn't matter whether it is a slot or signal) is not called. I've stepped into QMetaObject::invokeMethod with debugger, followed it till it called PostMessage (it is Qt 4.6.2 on Windows, by the way) – everything seemed to be OK. Object pointed to by data lives in GUI thread, I've double-checked this. How can I debug this problem? Or, better, maybe sidestep it altogether?

• Getting All categories in external page.

  - by Harsha

  This is very basic magento question i guess. I want to first get all the store categories, then loop through them to get their sub-categories and products and similarly continue till the last sub-category. I will be using this in an external page having Mage::app() declared at the top of the page. I am not aware of the Magento API's(if thats wat they are called) to use to get this functionality. Remember I am not using this in any of the templates, so something like getCurrentCategory() will not work here i guess. Also please guide if there are any good resources to search for particular functionality in magento and API's to implement it, or am i doomed to go through their phpdoc to know the list of methods. Any help here will be greatly appreciated, Thanks.

• What are the possible tags of "global" tag in Magento "config.xml" file?

  - by Knowledge Craving

  Can someone professional experienced Magento developer tell me how to accomplish the following in Magento? I want to know what are the possible tags that can fit in the "global" tag of the "config.xml" page of every module's etc folder? I have tried searching for this answer at many places in Internet but in vain. Please provide the full details along with it, because I want at least the users accessing this website find it useful enough, instead of scratching their heads. I really want a detailed explanation, because every newbie like me gets totally confused at this point. From what I know till now, is that in this page, you can set routers, rewrites, cron jobs, admin html, front-end html and many more. But without any strong concepts. So please I want that strong fundamental concept with a detailed explanation about it.

• How to find hidden properties/methods in Javascript objects?

  - by ramanujan

  I would like to automatically determine all of the properties (including the hidden ones) in a given Javascript object, via a generalization of this function: function keys(obj) { var ll = []; for(var pp in obj) { ll.push(pp); } return ll; } This works for user defined objects but fails for many builtins: repl> keys({"a":10,"b":2}); // ["a","b"] repl> keys(Math) // returns nothing! Basically, I'd like to write equivalents of Python's dir() and help(), which are really useful in exploring new objects. My understanding is that only the builtin objects have hidden properties (user code evidently can't set the "enumerable" property till HTML5), so one possibility is to simply hardcode the properties of Math, String, etc. into a dir() equivalent (using the lists such as those here). But is there a better way?

• ASP SaveToDisk method takes an incredible amount of time

  - by burnt_hand

  This is a method in ASP Classic that saves a file to disk. It takes a very long time but I'm not sure why. Normally, I wouldn't mind so much, but the files it handles are pretty large so need this needs to faster than 100kB a second save. Seriously slow. (old legacy system, band aid fix till it gets replaced...) Public Sub SaveToDisk(sPath) Dim oFS, oFile Dim nIndex If sPath = "" Or FileName = "" Then Exit Sub If Mid(sPath, Len(sPath)) <> "\" Then sPath = sPath & "\" '" Set oFS = Server.CreateObject("Scripting.FileSystemObject") If Not oFS.FolderExists(sPath) Then Exit Sub Set oFile = oFS.CreateTextFile(sPath & FileName, True) For nIndex = 1 to LenB(FileData) oFile.Write Chr(AscB(MidB(FileData,nIndex,1))) Next oFile.Close End Sub I'm asking because there are plenty of WTF's in this code so I'm fighting those fires while getting some help on these ones.

• Remote connect to mysql?

  - by chobo2

  Hi I don't use php or mysql but I am trying to upgrade a phpbb board I got but the one click installer forgot to install some stuff in the database so I can't upgrade to the newest version till I add the missing stuff. So I need to do a remote connect to mysql database but I am not sure how to do this or what software I need(free, and very easy to setup I don't want to spend much time on this). I don't really want to use phpmyadmin since I don't want to start setting up a virtual directory and whatever else it needs to be installed. Like I said I don't do php or mysql I just choose it since in my hosting package it was one click to install phpbb and I had a mysql database free. Thanks

• MultiThreading question

  - by TiGer

  Hi, I am developing on Android but the question might be just as valid on any other Java platform. I have developed a multi-threaded app. Lets say I have a first class that needs to do a time-intensive task, thus this work is done in another Thread. When it's done that same Thread will return the time-intensive task result to another (3rd) class. This last class will do something and return it's result to the first-starting class. I have noticed though that the first class will be waiting the whole time, maybe because this is some kind of loop ? Also I'd like the Thread-class to stop itself, as in when it has passed it's result to the third class it should simply stop. The third class has to do it's work without being "incapsulated" in the second class (the Thread one). Anyone knows how to accomplish this ? right now the experience is that the first one seems to be waiting (hanging) till the second and the third one are done :(

• Read Core data in Serial Queue for iPhone app

  - by user1277209

  I have an app which uses Core data and the values are fetched from a link on internet. This runs absolutely fine when I am creating a serial queue in AppDelegate and I am not facing any problem with the same. Now, when I am trying to re-create similar scenario in a UITableViewController and executing the same in a serial queue but when the control reaches NSError *error; NSArray *match = [context executeFetchRequest:fetchRequest error:&error]; execution control disappears and then this code remains in the execution till eternity. Can anyone help me with what exactly is wrong here? FYI, I am passing the same ManagedObjectContext to the serial queue.

• log file not generated while accessing a jar having log4j support.

  - by naveen garimella

  I have a x.jar which is being used by some client y.jar. Both x.jar and y.jar are at the same package level. i have put the log4j.xml at the same package level. But the log file is never generated. Can i know why? I have tried few other options as well but no luck till now. i have added log4j-1.2.16.jar to ClassPath: variable in manifest files of both x.jar and y.jar. Put log4j.xml at the class level of y.jar which actually calls the x.jar classes. package structure is as follows: x.jar --manifest.mf has a entry ClassPath:log4j-1.2.16.jar y.jar --manifest.mf has a entry ClassPath:log4j-1.2.16.jar log4j-1.2.16.jar log4j.xml --has a RollingFileAppender.

• Questions about nhibernate.

  - by chobo2

  Hi I have a couple questions about nhibernate. I still don't understand what contextual sessions means. I do web stuff so I just choose "web" but I really don't know what it is doing. Should I put session.BeginTransaction() in Application_BeginRequest? Should I commit everything in Application_EndRequest? Or should I commit when needed. Say I need to insert a user and then down in some code later I need to update some other table. Should I make the user and do the update then finally commit or should I wait till both are ready to be commited? Should you always have session.Rollback() in Application_EndRequest? Should I session.close() or session.dispose() or both in Application_EndRequest?

• Highest value datatype can store in c#

  - by user472832

  I am writing a small program for my assignment to find the primitive roots of a prime number. So far, the program works for smaller prime numbers till 13 and gives correct number of roots. But for higher primes numbers, it is showing only fewer primitive roots. And now i got stuck for the prime number 41, shows no primitive roots for it. I used DOUBLE datatype for the calculation, and again tried with the datatype DECIMAL, but no luck. Does anyone know about this kind of problem??? Thank you.

• can not find out if the div element is already set in body in chrome extension

  - by alpham8

  in my chrome extension I got an div, which I will add to the body of the current tab. I am listening to chrome.tabs.onUpdated. If this event is called, I execute a script inside content_scripts. In this function there I´ll wait till the document is ready with jQuery $(document).ready(...). I try to access $("#div").length and sometimes it returns 1 and sometimes 0. It should added to the body, if it´s not already there. For some strange reasons, the onUpdated event is called twice on each page reload. Actually I found no way to check safely if the div was already added.
