• Visual Studio 2008 profiler analysis - missing time

  - by Scott Vercuski

  I ran the Visual Studio 2008 profiler against my ASP.NET application and came up with the following result set. CURRENT FUNCTION TIME (msec) ---------------------------------------------------|-------------- Data.GetItem(params) | 10,158.12 ---------------------------------------------------|-------------- Functions that were called by Data.GetItem(params) TIME (msec) ---------------------------------------------------|-------------- Model.GetSubItem(params) | 0.83 Model.GetSubItem2(params) | 0.77 Model.GetSubItem3(params) | 0.76 etc. The issue I'm facing is that the sum of the Functions called by Data.GetItem(params) do not sum up to the 10,158.12 msec total. This would lead me to believe that the bulk of the time is actually spent executing the code within that method. My question is ... does Visual Studio provide a way to analyze the method itself so I can see which sections of code are taking the longest? if it does not are there any recommended tools to do this? or should I start writing my own timing scripts? Thank you

• Problem about socket communication

  - by Ahmet Altun

  I have two separate socket projects in VS.NET. One of them is sender, other one is receiver. After starting receiver, i send data from sender. Although send method returns 13 bytes as successfully transferred, the receiver receives 0 (zero). The receiver accepts sender socket and listens to it. But cannot receive data. Why? P.S. : If sender code is put in receiver project, receiver can get data, as well.

• Random List of millions of elements in Python Efficiently

  - by eWizardII

  Hello, I have read this answer potentially as the best way to randomize a list of strings in Python. I'm just wondering then if that's the most efficient way to do it because I have a list of about 30 million elements via the following code: import json from sets import Set from random import shuffle a = [] for i in range(0,193): json_data = open("C:/Twitter/user/user_" + str(i) + ".json") data = json.load(json_data) for j in range(0,len(data)): a.append(data[j]['su']) new = list(Set(a)) print "Cleaned length is: " + str(len(new)) ## Take Cleaned List and Randomize it for Analysis shuffle(new) If there is a more efficient way to do it, I'd greatly appreciate any advice on how to do it. Thanks,

• PHP MVC: How to implement an effective Controller/View Association like ZendFramework guys do!

  - by Navi

  Hi, I am making my own PHP-MVC framework. i have a question regarding Controller and View Association. I love the way Zend framework uses view within Controller as follow: $this->view->data = 'Data here'; so it can be used in view as follow: echo $this->data; I am wondering how can i implement this association. I want to remove codes between /** **/ and want to replace with some magic functions. My codes for controller as as follow: class UserController extends Controller{ /************************************/ public function __construct(){ $this->view = new View(); $this->view->setLayout( 'home' ); } function __destruct(){ $this->view->render(); } /************************************/ public function index(){ $this->redirect('user/login'); } public function login(){ } public function register(){ } public function forgotPassword(){ } } Thanks and best regards, -Navi

• SQL: without a cursor, how to select records making a unique integer id (identity like) for dups?

  - by Dr. Zim

  If you have the select statement below where the PK is the primary key: select distinct dbo.DateAsInt( dateEntered) * 100 as PK, recordDescription as Data from MyTable and the output is something like this (the first numbers are spaced for clarity): PK Data 2010 01 01 00 New Years Day 2010 01 01 00 Make Resolutions 2010 01 01 00 Return Gifts 2010 02 14 00 Valentines day 2010 02 14 00 Buy flowers and you want to output something like this: PK Data 2010 01 01 01 New Years Day 2010 01 01 02 Make Resolutions 2010 01 01 03 Return Gifts 2010 02 14 01 Valentines day 2010 02 14 02 Buy flowers Is it possible to make the "00" in the PK have an "identity" number effect within a single select? Otherwise, how could you increment the number by 1 for each found activity for that date? I am already thinking as I type to try something like Sum(case when ?? then 1 end) with a group by.

• Linq ChangeConflictException (ASP.NET MVC) - occurs when submitting DataContext changes

  - by Alex

  System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n) This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right? What's the problem here and how can I fix it?

• Trigger an action to increment all rows of an int column which are greater than or equal to the inserted row

  - by Dev

  I am performing some insertion to an SQL table with has three columns and several rows of data The three columns are Id,Product,ProductOrder with the following data Id Product ProductOrder 1 Dell 1 2 HP 3 3 lenovo 2 4 Apple 10 Now, I would like a trigger which fires an action and increments all the ProductOrders by 1which are greater than or equal to the inserted ProductOrder. For example, I am inserting a record with Id=5 Product=Sony, ProductOrder=2 Then it should look for all the products with ProductOrder greater than or equal to 2 and increment them by 1. So, the resultant data in the SQL table should be as follows Id Product ProductOrder 1 Dell 1 2 HP 4 3 lenovo 3 4 Apple 11 5 Sony 2 From above we can see that ProductOrder which are equal or greater than the inserted are incremented by 1 like HP,Lenovo,Apple May I know a way to implement this?

• iPhone: Error and error handling confusion in comparison.

  - by Mr. McPepperNuts

  NSArray *results = [managedObjectContext executeFetchRequest:request error:&error]; if(results == nil){ NSLog(@"No results found"); searchObj = nil; }else{ if ([[[results objectAtIndex:0] name] caseInsensitiveCompare:passdTextToSearchFor] == 0) { NSLog(@"results %@", [[results objectAtIndex:0] name]); searchObj = [results objectAtIndex:0]; }else { NSLog(@"No results found"); searchObj = nil; } } The code above compares data a user enters to data pulled from a database. If I enter data which is in the database; it works. But if I enter complete gibberish it returns the error below instead of "No results found." *** WebKit discarded an uncaught exception in the webView:shouldInsertText:replacingDOMRange:givenAction: delegate: <NSRangeException> *** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0) The results array being null should be accounted for during the checks in the above code, no?

• UNIX FIFO: How to allow only one writer/reader pair to use a FIFO?

  - by Max Krug

  Hi! I've written two programs: the first, the "writer", creates a FIFO and writes data into it. The second one, the "reader" runs in background and looks for data in the FIFO. Once data is there, the reader reads it out. If I start e.g. two writers and two readers, they all can write/read into/from the same FIFO. How can I restrict it for 3rd and 4th readers/writers to use the FIFO and allow only one writer and one reader to use the FIFO? thanks a lot. -- kind regards, Max Krug

• Cilk or Cilk++ or OpenMP

  - by Aman Deep Gautam

  I'm creating a multi-threaded application in Linux. here is the scenario: Suppose I am having x instance of a class BloomFilter and I have some y GB of data(greater than memory available). I need to test membership for this y GB of data in each of the bloom filter instance. It is pretty much clear that parallel programming will help to speed up the task moreover since I am only reading the data so it can be shared across all processes or threads. Now I am confused about which one to use Cilk, Cilk++ or OpenMP(which one is better). Also I am confused about which one to go for Multithreading or Multiprocessing

• From comma separated list to individual item result set. *mysql

  - by Raziel

  I'm doing some data migration from a horribly designed database to a less horribly designed database. There is a many to many relationship that has a primary key in one table that corresponds to a comma separated list in another. FK_ID | data ------------- 1,2 | foo 3 | bar 1,3,2 | blarg Is there a way to output the FK_ID field with each comma separated element as a single line in the result set? result set FK_ID | data ------------- 1 | foo 2 | foo 3 | bar 1 | blarg 2 | blarg 3 | blarg I'm thinking this would require some sort of recursive query which I don't think mysql has. Thanks in advance.

• HSQLDB and in-memory files

  - by lewap

  Is it possible to setup HSQLDB in a way, so that the files with the db information are written into memory instead of using actual files? I want to use hsqldb to export some data structures together with hibernate mappings. Is is, however, not possible to write temporary files, so that I need to generate the files in-memory and return a stream with their contents as a response. Setting hsqldb to use nio seems not to be a solution, because there is no way to get hold of those files before they get written onto the filesystem. What I'm thinking of is a protocol handler for hsqldb, but I didn't find a suitable solution yet. Just to describe in other words: A hack solution would be to pass hsqldb a stream or several streams. It would then during its operation write data into those streams. After all data is written, the user of the db could then use those streams to send it back over the network.

• Overriding fetch in multiple spine models

  - by Adam Charnock

  I need to override Spine's @fetch() method in all of my Spine models. Currently I have code duplication as follows: TastypieEndpointMixin = fromJSON: (data) -> return unless data return Spine.Model.fromJSON(data.objects) class App.models.Position extends Spine.Model @configure 'Position', 'code', 'name' @extend Spine.Model.Ajax @extend TastypieEndpointMixin @url: '/api/v1/position/?format=json' validate: -> 'code is required' unless @code @fetch: -> defer = $.Deferred() @one "refresh", -> defer.resolve() super return defer class App.models.Player extends Spine.Model @configure 'Player', 'first_name', 'last_name', ... @extend Spine.Model.Ajax @extend TastypieEndpointMixin @url: '/api/v1/player/?format=json' @fetch: -> defer = $.Deferred() @one "refresh", -> defer.resolve() super return defer My question is: How can I create some form of parent class which contains @fetch()? I know this should be a simple problem to solve. I have tried many options (including extending Spine.Model and Spine.Model.Ajax), but nothing works and I cannot seem to get my head around it.

• Best approach to create a security environment in Java

  - by Tom Brito

  I need to create a desktop application that will run third party code, and I need to avoid the third party code from export by any way (web, clipboard, file io) informations from the application. Somethig like: public class MyClass { private String protectedData; public void doThirdPartyTask() { String unprotedtedData = unprotect(protectedData); ThirdPartyClass.doTask(unprotectedData); } private String unprotect(String data) { // ... } } class ThirdPartyClass { public static void doTask(String unprotectedData) { // Do task using unprotected data. // Malicious code may try to externalize the data. } } I'm reading about SecurityManager and AccessControler, but I'm still not sure what's the best approach to handle this. What should I read about to do this implementation?

• Communication between (Desktop/Smartphone) Application and Web Application

  - by erlord

  Hi all I wonder what is the commonly used method and protocol for a, say, smartphone application to send its data to a web application (where these data should be proceeded and stored). My naive beginner's approach would be something like this: From my smartphone app, use a framework encoding my data object into a json object Send this object via http to a listener addressed by a dedicated URL On the server side, use a JSON parser and store it via ORM etc. into a database Questions: Is this too naive? 2a. If yes: What is the appropiate way to tackle this workflow? 2b. If no: What frameworks to use in JAVA for serializing/deserializing to/from JSON objects? Any example for a json listener in the web? Tutorial for a http-protocol based Java listener? Thanks for all answers and suggestions in advance. Regs Me

• i2c on silicon image c8051f32x (using USBXpress)

  - by tosa

  I have the I2C (SMBus) working properly in this uC and have a VB GUI which can communicate over USB (using USBXpress) and do I2C transactions from the uC to a separate IC. The problem is that I am having the uC poll a register on the IC every 1s. When I do an asynchronous GUI I2C transaction, every once in a while, I believe it collides with the polling I2C transaction and all the I2C data gets shifted at the GUI (i.e., register 0x00's data shows up on register 0x01) . The I2C data in the IC looks correct (by spying on the I2C bus with a LA). What exactly is happening and how can I fix this?

• What exactly is Two-way databinding in WPF ?

  - by blntechie

  I'm learning WPF with MVVM and for a starter, I viewed Jason Dolinger's video on MVVM . In that he mentioned, that one of the advantage of using MVVM with WPF is two-way data binding. My question is what does he mean by two-way data binding? Is that the feature of ability to 1) bind data from controls(View) to properties in VM and 2) any change in collections or properties are reflected in the view? If I'm wrong, can anyone please explain me in detail what it is and what are its advantages? This might be a very simple doubt, but I'm very new to WPF and it's terminologies and moving away from WinForms now.

• ASP.net repeater, scroll 3 at a time

  - by Christo Fur

  I have a list of data that I need to display in a web page 3 at a time The first needs to be displayed in a div called "left" , the second in a div called "centre" and the third in a div called "right". And I need to be able to scroll through the data with a pager. And so the next 3 results will be displayed in a similar way, and so on till the end of the data set Obviously the alternating templates in the repeater are not suitable for this. Is there a smarter way to achieve this?

• Best way to show a loading screen in an iPhone app?

  - by pkulak

  I'm building what is essentially a web app. Every piece of data has to be fetched from a web API. So, every UITableView that I show takes some amount of time to fill with data and I'm struggling to find a good way to show the user a loading screen. Right now I'm popping up an action sheet, but that just seems a bit wrong. Ideally, I'd popup up a blank view over the tableview with "Loading..." on it, then fade it away when the data comes in, but I can't think of a way to do that in 8 places in my app without massive code duplication.
