• Magento coupon entities in database

  - by koramaiku

  I'm trying to develop a Magento plugin which involves using coupons. Apparently after looking around I found I found a source that mentions use of a 'salesrule' table for coupons. However when I looked at my database i couldn't find it. However I did find 3 tables that had mention 'coupon' called 'coupon_aggregated', 'coupon_aggregated_order', and 'coupon_aggregated_updated'. I just wanted to know what is the difference between the 3 tables so I can start using them? I am on the latest version of Magento. Thanks guys in advance.

• Import a number of csv files and replace NA by Zeros

  - by tao.hong

  I know how to do this individually. However, I have more than 1000 files. I decided to use a for loop. However, it seems like I did not find the correct way to evaluate my variables. Here is my code setwd('C:/data') filenames=dir() #find file names for (i in filenames){ adt = substr(x = i, start = 1, stop = nchar(i)-4) name=paste("data_", adt, sep="") assign(name, read.csv(i,header=T,sep=",")) #read each file and assign a variable name starting with data_ to it func=paste('name[is.na(name)] <- 0',sep="") # here is the place I have problem. R will not consider name is a parameter whose values change in each iteration eval((text=func)) }

• NSIS already installed product

  - by Buba235

  Hello! I have some problem with my created nsis setup. I need to check if the product is already installed and then get the path to the already installed product. This is because I want to build a "Feature-Setup" that installs some other components into the previous installed folder. Does anyone know how to build this installer? It will be brilliant if the feature setup will start the installation and check the path of the installed product. After checking is done the path should be (read only) in "Destination Folder" under "Choose Install Location". Thanks for any help Buba

• Container for database-like searches

  - by Milan Babuškov

  I'm looking for some STL, boost, or similar container to use the same way indexes are used in databases to search for record using a query like this: select * from table1 where field1 starting with 'X'; or select * from table1 where field1 like 'X%'; I thought about using std::map, but I cannot because I need to search for fields that "start with" some text, and not those that are "equal to". I could create a sorted vector or list and use binary search (breaking the set in 2 in each step by reading the element in the middle and seeing if it's more or less than 'X'), but I wonder if there is some ready-made container I could use without reinventing the wheel?

• Activity should be transparent, but has black background

  - by Uwe Krass

  I followed the instructions of writing a transparent layout. My res/values/style.xml looks like this: <resources> <style name="Theme" parent="android:Theme" /> <style name="Theme.Transparent"> <item name="android:windowBackground">@drawable/transparent_background</item> </style> <drawable name="transparent_background">#00000000</drawable> </resources> The activity snippet looks like this: <activity android:name=".Controlls" android:label="Controlls" android:theme="@style/Theme.Transparent"> When I start this activity from my root activity, the layout gets drawn correctly, but the background stays black.

• Best ASP.NET Background Service Implementation

  - by Jason N. Gaylord

  What's the best implementation for more than one background service in an ASP.NET application? Timer Callback Timer timer = new Timer(new TimerCallback(MyWorkCallback), HttpContext, 5000, 5000); Thread or ThreadPool Thread thread = new Thread(Work); thread.IsBackground = true; thread.Start(); BackgroundWorker BackgroundWorker worker = new BackgroundWorker(); worker.DoWork += new DoWorkEventHandler(DoMyWork); worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(DoMyWork_Completed); worker.RunWorkerAsync(); Caching like http://www.codeproject.com/KB/aspnet/ASPNETService.aspx (located in Jeff Atwood's post here) I need to run multiple background "services" at a given time. One service may run every 5 minutes where another may be once a day. It will never be more than 10 services running at a time.

• How to create a step by step wizard in C++ (with unmanaged code) in Visual Studio 2010

  - by Alex. S.

  I would like to build a small wizard in C++ with no dependencies on any framework. Apparently, is really simple, but I don't know where to start. Can you point me to good information (tutorials, etc) on it. Should I use MFC Application or a Win32 project? Is there any step by step guide ? I'm using VS 2010. The majority of info I'd found on MFC is really old. It seems like the vast majority of development is going .net.

• oracle display for every stored procedure the execution time

  - by CC

  Hi all. I'm working on a stored procedure. Inside this one, there are many call to the other stored procedures. There are a bunch of them. I was wondering if there is a option to be able to have the execution time of every stored procedure involved, every function (with a start and end time, ior something like that). The idea is that I need to optimise it and I should touch every part, and since I not sure where is the longest execution time, is a bit difficult. And after a modification I would like the see the hole process if it's shorter or not. If I call the procedure from unix, using sql plus, I have no log. If I call it from TOAD, it's blocked until the end. Any idea? I'm not a dba, so I don't have many rights on the database, I'm just a regular user. Thanks for any advice. C.C.

• How to create a Appointment in a Shared Calendar (Sharepoint) with VBA (Macro)?

  - by Diogo K.

  I am actually trying to make an appointment from an excel spreadsheet. I have all the information of the appointment, like subject, body, start and end dates, I actually can create an appointment but only with my personal calendar in outlook. How do I copy/move/create an appointment in a shared calendar in a sharepoint server? I've tried: Dim apOL As Object Dim objFolder As Folder Dim cro As String Set apOL = CreateObject("Outlook.Application") Set oItem = apOL.CreateItem(olApItem) Set MAPISession = apOL.Session ... cro = "stssync://sts/?ver=1.0&type=calendar&cmd=add-folder&base-url=(MY SP SERVER)&list-url=%2FLists%2FCronograma%20%20%2Fcalendar%2Easpx&guid=%7B02717CEF%2D404F%2D482F%2DA131%2D5C3C245CD268%7D&site-name=Testes&list-name=Cronograma%20-" ... Set objFolder = MAPISession.OpenSharedFolder(cro, Null,Null,Null) It gives me the error "Type Mismatch" I'd try to get the objFolder as the Sharepoint Folder then later create an local appointment and then try an Item.Move objFolder Is it the correct way?

• How can I configure my windows service in the code to access the desktop?

  - by Pankaj

  I have created an windows service. I want to open some windows based application from this service. But my windows service is unable to start desktop applications. To enable the access I had to do the following steps: Opened the administrative tool "Services" Right clicked on my service and had to select "properties" Then in the "Log On" tab, selected "Allow service to interact with desktop". After that my service can open desired windows based processes. Can I configure my windows service in the code (C#) to access the desktop so that I won't have to change the access permission manually after installation?

• Write a network simulator for fun

  - by Jono

  I want to write my own network simulator, for fun and for personal challenge. I hope to learn both new programming techniques, and a little bit more about networking. Previous object-oriented attempts ended very quickly, but I've recently downloaded and played with Microsoft's Axum (a new version was released today) and their Concurrency and Co-ordination Runtime. As I come from a very OO dominant background, I had never heard of Actor-oriented programming before; now it seems I've had my head in the sand until Scala and F# brought the paradigm to me. My questions are: a) is actor-oriented programming a better choice than object-oriented programming for this task, and if so b) where is a good place to start learning actor-oriented design?

• SSL: can the secret key be sniffed before the actual encryption begins?

  - by Jorre

  I was looking into SSL and some of the steps that are involved to set up an encrypted connection between a server and a client computer. I understand that a server key and certificate is sent to the browser, and that a secret code is being calculated, like they say in the following video: http://www.youtube.com/watch?v=iQsKdtjwtYI around 5:22, they talk about a master secret code that is being calculated to start talking in an encrypted way. My question now is: before the connection is actually encrypted (the handshake phase), all communication between the server and the client can be sniffed by a packet sniffer. Isn't it then possible to sniff the encryption key or other data that is used to set up a secure connection?

• Build Path issue with Java Android project when starting Eclipse

  - by Matt Smith

  I booted up eclipse to start on a project, and without typing in a word I already have several errors. package department.namespace; import android.app.Activity; import android.os.Bundle; public class DepartmentActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } At package department.namespace, it says: multiple marks at this line and the type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files The import android.os cannot be resolved. Override cannot be resolved as a type The method OnCreate(Bundle) is undefined for the type Activity R. cannot be resolved as a variable. Since this JUST came up when I started Eclipse, how do I fix this?

• Logging fatal/parse errors in PHP5

  - by PeterBelm

  I'm writing an error logging service that will be integrated into websites running on my server, that will email me error batches, etc. So I've been trying to find out if there's a way to handle fatal and parse errors, however not using the tricks to handle it in PHP code (output buffer, shutdown function). I'm quite happy to write some C code or something to handle it outside of my PHP code. I would also like to issue a redirect if possible (my sites use output buffering so there shouldn't be any headers sent). I'm pretty sure this could be done with a PHP module, but I've never written one and have no idea where to start.

• Best Tools for Software Maintenance Engineering

  - by Pev

  Yes, the dreaded 'M' word. You've got a workstation, source control and half a million lines of source code that you didn't write. The documentation was out of date the moment that it was approved and published. The original developers are LTAO, at the next project/startup/loony bin and not answering email. What are you going to do? {favourite editor} and Grep will get you started on your spelunking through the gnarling guts of the code base but what other tools should be in the maintenance engineers toolbox? To start the ball-rolling; I don't think I could live without source-insight for C/C++ spelunking. (DISCLAIMER: I don't work for 'em).

• How to run lengthy tasks from an ASP.NET page?

  - by Jimmy C

  I've got an ASP.NET page with a simple form. The user fills out the form with some details, uploads a document, and some processing of the file then needs to happens on the server side. My question is - what's the best approach to handling the server side processing of the files? The processing involves calling an exe. Should I use seperate threads for this? Ideally I want the user to submit the form without the web page just hanging there while the processing takes place. I've tried this code but my task never runs on the server: Action<object> action = (object obj) => { // Create a .xdu file for this job string xduFile = launcher.CreateSingleJobBatchFile(LanguagePair, SourceFileLocation); // Launch the job launcher.ProcessJob(xduFile); }; Task job = new Task(action, "test"); job.Start(); Any suggestions are appreciated.

• Analyzing CPU usage of an iOS application

  - by Mustafa

  I'm working on an application that constructs springboard like interface (like iPhone's home screen). I have multiple pages, and each page contains many subviews. Each subview is able to detect touch and hold event. Once a touch and hold event is recognized, all the subviews start to wobble. One of the problems that i'm facing is that the CPU usage shoots to 99%, when the subviews are in wobble state, and i change the page. Instruments has a tool by the name of "CPU Sampler". I'm unable to find good set of documentation for this tool. I don't know how to read the output generated by this tool. Can anyone give me a small tutorial or guidelines? Can i check which piece of code is responsible for the CPU activity?

• Can you control pinterest's "find image" results?

  - by anthony

  Rather than add Pin It buttons through our site, I would like to simply control what images show up in Pinterest's "Find Image" results if a user decides to pin one of our URLs. As of now, "Find Images" allows the user to scroll through the images it finds on the page so they can select which image to pin. The "found" images start with the first jpg in the html file, I'm assuming (could that be a bad assumption??). On our site, this forces a user to scroll through about 15 navigation and promotion images before arriving at the featured product image. Is there any way to specify this image to show first in those results? Maybe through a meta tag, or by adding a class or id to the element? Without a public Pinterest API, this seems like just guesswork, but I wanted to see if anyone else has run into this, or solved this. Thanks.

• border highlighting loop with jquery

  - by Tek

  I'm having trouble coming up with a loop that changes the border color of an image from black to yellow and yellow to black over x seconds. Then applying an interrupt to the loop when the image gets clicked on. I don't know where to start, can someone point me in the right direction? I think I may be using the wrong tools to properly write this. Here's what I've come up so far, though if there's a better way to write this, do share! for( i = 100; i >= 0; i--) { $("#imgid").css("border-color", 'rgb(' + i + '%,' + i + '%,0)'); } I'm having trouble picturing how I could combine two loops so that I can also count upwards as well so that it will turn into yellow and back to black. I also don't know how to go about controlling the amount of time it takes for that loop to execute and creating an interrupt when #imigid is clicked. Which is where I'm not sure how to write.

• Reflection: take values from an unknown running alpplication

  - by Dr.Lesh

  I'm writing an application that searchs for Semaphore types in the fields of unknown classes in unknown application (passed by user). I made it using Reflection and it worked. Now I want to fill up these semaphores with values, taking them from a running instance of this unknown application. So i took the class with "main" method of this unknown application, made a newInstance, and passed it when invoking the main method to start the application: Class mainClass = getItSomeWhere(); Object instance = mainClass.newInstance(); Method mainMethod = mainClass.getDeclaredMethod("main", new Class[]{String[].class}); mainMethod.invoke(instance, new Object[]{args}); and it worked fine. Now, how can I get the semaphore values, taking them from the classes of this running application, when I only have an instance of the main class? Many thanks for the answers.

• How do you get Windows Mobile Device Center to detect a Windows Phone 7 Series emulator?

  - by sweeney

  Hello, I'm running some tests and need to be able to get Windows Phone 7 Series emulator synced with an exchange account or local Outlook account via the Device Center. I'm using the unlocked version of the emulator so that i actually have a reasonable set of software on the phone to work with. When the emulator launches i expect the Device Center to detect it and start syncing (or prompt me for settings). This does not happen. I've tried adjusting the Connection Settings (COM2 and DMA) in the Device Center with no luck. Is this possible? Has anyone done it? Thanks in advance!
