• Any good Open Source or Cheap ASP.NET Catalog Applications

  - by Zhaph - Ben Duguid

  We're looking for a cheap-to-free "off the shelf" ASP.NET catalogue application, that will meet the following requirements: Support two kinds of listings: Suppliers of Services Suppliers of Products, and their Products Suppliers can be categorised by: Area of specialisation - including sub-categories Location Other data, e.g. where listing came from Versioning of supplier/product details Easy to use management interface Use masterpages so we can drop it into our existing site layout Run on a Windows 2003 server, with .NET 3.5 installed In an ideal world, the following additional requirements might be met: Suppliers can manage their own listings Other products that are available to us (that will obviously need some additional development to meet these requirements) are: Content Management System (MS) Commerce Server - bear in mind we're not selling the products/suppliers, just listing them Simple DB application. I'm happy to knock something up in MCMS/simple DB, I'm just looking to see if anyone's had any experience with off the shelf apps that could save us some time. I'm also happy to receive "Don't use this because" type answers. Thanks.

• Rreport / LaTeX quality output package

  - by aL3xa

  I'm looking for some LaTeX template for creating quality output. On R-bloggers I've bumped on Frank Harrel's Rreport package. Due to my, quite modest LaTeX abilities, only user-friendly (and noob-friendly) interface should suffice. Here's a link to an official website. I'm following the instructions, but I cannot manage to install an app. I use Ubuntu 9.10, R version is 2.10.1 (updated regularly from UCLA's CRAN server)... of course, cvs is installed on my sistem. Now, I'd like to know is there some user-friendly LaTeX template package (Sweave is still to advanced/spartan for me). I'm aware that my question is quite confounding, but brief glance on examples on Rreport page should give you a hint. I'm aware that LaTeX skills are a must, but just for now I need something that will suite my needs (as a psychological researcher). Is there any pandan for Rreport package?

• Django QuerySet filter + order_by + limit

  - by handsofaten

  So I have a Django app that processes test results, and I'm trying to find the median score for a certain assessment. I would think that this would work: e = Exam.objects.all() total = e.count() median = int(round(total / 2)) median_exam = Exam.objects.filter(assessment=assessment.id).order_by('score')[median:1] median_score = median_exam.score But it always returns an empty list. I can get the result I want with this: e = Exam.objects.all() total = e.count() median = int(round(total / 2)) exams = Exam.objects.filter(assessment=assessment.id).order_by('score') median_score = median_exam[median].score I would just prefer not to have to query the entire set of exams. I thought about just writing a raw MySQL query that looks something like: SELECT score FROM assess_exam WHERE assessment_id = 5 ORDER BY score LIMIT 690,1 But if possible, I'd like to stay within Django's ORM. Mostly, it's just bothering me that I can't seem to use order_by with a filter and a limit. Any ideas?

• Providing multi-version databases for backward compatibility for production applications/databases.

  - by JavaRocky

  How can I manage multiple versions of a database easily? I have some data (as views as selects for data originating in tables from other schemas), which other database may reference using various means including database synonyms & links. I wish to provide a sort of interface/guarantee in-case future for applications/databases which use this data. All of this is for in the event i need to update the views for correctness or applicability inside my database. How can i achieve this in a maintained, controlled and easy way? I am using Oracle 10g if that matters.

• iPhone Objective-C/Plain C Memory Management

  - by toc777

  Hi everyone, I understand Objective-C memory management but I'm using Core Graphics functionality such as CGRect, CGPoint, CGImageRef etc.. which is written in plain C. My question is how do i manage this memory or is it already handled for me? According to the Apple documentation if an Apple Objective-C function doesn't have copy, new or create in it the returned object is managed for you using autorealease. Is this true for the Core Graphics stuff also? (Well i guess it wont be using autorealease but maybe something similar?) Thanks for taking the time to read this.

• Sharepoint SSRS: Unexpected Error Encountered

  - by Nicholas

  We are running an intranet website hosted on Sharepoint 2007, serving reports to users via SSRS. Recently, our users are experiencing error when trying to access certain reports with the error message "An unexpected error has occurred". After trying many things, to cut a long story short we manage to temporarily solve the problem by manually running UPDATE STATISTICS on the tables in the database. However, this error will periodically crop up again and again, running UPDATE STATISTICS immediately solved it. I had suggested to run a daily job in the server to auto run UPDATE STATISTICS every few hours or so but was rejected by my team lead. Is there any other workaround for this error? Why does UPDATE STATISTICS solve the problem, I still not very understand?

• Drupal 5: CCK fields in custom content type

  - by Kuroki Kaze

  I have module that implements custom content type via NodeAPI hooks (hook_insert, hook_update etc). I want to add CCK field to this content type and populate it via hook_nodeapi calls like create or update (to show content nodes in Views). Problem is, I cannot access CCK fields for this content type. Sure, it's enabled on "Manage Fields" page, but when I load any node of this type with Devel module, I cannot see field attribute (field_flag) in node object. I can see it under "Dev Render" tab as part of "content" attribute, like $node-content['field_flag']['#value'], but if I assign value to $node-field_flag or $node-content['field_flag']['#value'] and call node_save, CCK fields are not saved. Maybe I must call some other function to save CCK fields? Or what may be wrong with this setup?

• Using git branches for variations of a project

  - by Trevor Hartman

  I'm using git's branching feature to manage 5 variations of a small website. There are 5 versions that will all be live in different subdirectories on production. My approach to checking out the various branches to their respective folders was to: mkdir foo && cd foo git init git remote add origin git@...:project.git git fetch origin foo:foo Where "foo" is a given branch name. This was fine, except for that it pulled my entire repo (designs, as3 source, etc...) into those branch folders instead of just the public www folder, which is the only thing I really want on production. Is there a cleaner way to handle this? Git can't clone subdirectories right?

• How to measure the time HTTP requests spend sitting in the accept-queue?

  - by David Jones

  I am using Apache2 on Ubuntu 9.10, and I am trying to tune my configuration for a web application to reduce latency of responses to HTTP requests. During a moderately heavy load on my small server, there are 24 apache2 processes handling requests. Additional requests get queued. Using "netstat", I see 24 connections are ESTABLISHED and 125 connections are TIME_WAIT. I am trying to figure out if that is considered a reasonable backlog. Most requests get serviced in a fraction of a second, so I am assuming requests move through the accept-queue fairly quickly, probably within 1 or 2 seconds, but I would like to be more certain. Can anyone recommend an easy way to measure the time an HTTP request sits in the accept-queue? The suggestions I have come across so far seem to start the clock after the apache2 worker accepts the connection. I'm trying to quantify the accept-queue delay before that. thanks in advance, David Jones

• How to show only border of window (winforms) when resizing in C#?

  - by MartyIX

• Use WPF DLL Assembly in ASP.NET problem

  - by liimur

  Hello, I have C++ project that compiles as DLL Assembly in .NET 3.5 SP1 Project is used for Image rendering processing by using WPF (it loads 2 images from local folder, applies one image on another and saves the output file in the same folder). I want to use that that project as a reference in ASP.NET project to the rendering on the website. So I created simple Web Project in ASP.NET C# that uses C++ project as a Reference. Everything works great in ASP.NET Web Development Server (built-in Web server in VS2008). But once I publish this project to IIS on the same Machine or use IIS for debug instead of built-in Web server Image rendering it's not working anymore. I'm not getting any exceptions or error messages, it just output image is not processes as it supposed to be. If anyone know what could cause that I would really appreciate your insight!

• Suggest product catalog script/framework in PHP which doesn't displays product price

  - by Amit Kumar Jha

  Hey all, I am new to web development and have this project in hand where in I have to build a product catalogue. I don't want any cart functionality or other such features, I just want to display the products,their specifications and images etc. on the website and give my client an admin panel to manage products. Now I looked into various PHP shopping cart scripts but couldn't find a way to remove price info from the display. I am not experienced enough in web development to make a product catalogue from scratch so if you guys could point me out in right direction I would be very grateful. If you could give me link to some shopping cart or cataloguing script or any other way to accomplish the task it would help me out a lot.. Thanks in advance to all those who reply.

• Best way for programmers to edit XAML

  - by JessicaB

  I was wondering how programmers chose to edit XAML. Most of the programmers I speak to seem to edit the raw XML, but that seems nuts to me since it is such a natural thing for a more visual editor (of course you often have to get down to the raw code ultimately, but isn't there a better way to lay out a grid, or edit a template, or add non c# triggers or manage commands? The one that really set me off was editing a menu -- Visual Studio 1.0 had a better menu editor for C++ than the raw XAML editing experience.) When I edit .aspx files I use a visual editor much of the time, and then for the raw stuff I get into the html code. I am aware of Expression Blend, but that seems far more focused on artistic types and GUI experts rather than programmers. Does anyone have recommendations for a better editor for XAML than VS? Especially so since VS seems to have real nasty problems with XAML editing too, like bugginess and poor performance? Appreciate your helping this XAML newbie.

• Progressing Alfresco workflows through web script

  - by Domchi

  I have an Alfresco document reference; what I'm looking for is a way to access workflow attached to that document and finish it (or progress it to the next transition) through Javascript. Almost every example on the web shows how to start workflow, and from the dashlet I could call task command processor (/alfresco/command/task/end/[/transition]) if I knew the task ID, but how do I do the same thing from server-side web script starting only from the document reference? There must be a way to access workflows from document and manage them programatically.

• Running Sybase ISQL scripts from windows batch file

  - by user1328709

  I have already researched on this site as well as on google extensively for this. I have created a number of batch files that perform certain automated transactions(backups etc) on our production database. i want to further simplify my end of day processes by taking the dumps using a script that accepts input of some parameters. the script is able to login the isql prompt but unable to do the execution of the commands. @ECHO ***Started*** @ECHO Enter MonthDay(MMDD) SET /p md= @ECHO %md% mkdir \\10.20.1.17\arch\212%md%_banking set run=isql -Uuser -SORBITS -Ppass %run% @echo dump database banking to '/media/newArch/212%md%_banking/212%md%EOD_banking.dmp' with compression=5 @echo dump database master to '/media/newArch/212%md%_banking/212%md%EOD_master.dmp' @echo go pause I have been unsuccessful at putting these in a separate script file because the script itself uses a passed parameter. Please give me hints and links to Thanks

• Problem with StandardOutput stream in async mode.

  - by JF

  Hi everyone. I have a program that launches command line processes in async mode, using BeginOutputReadLine. My problem is that the .Exited event is triggered when there is still some .OutputDataReceived events being triggered. What I do in my .Exited event must happen only once all my .OutputDataReceived events are done, or I'll be missing some output. I looked in the Process class to see if anything could be useful to me, as to wait for the stream to be empty, but all I find is for sync mode only. Can any of you help? Thanx.

• List Management Via MailChimp API

  - by goombaloon

  I'm investigating using the MailChimp API to manage email notifications for a social networking site (similar to how Twitter sends email notifications to followers when a followee posts a new Tweet). My original plan was to have a "follower" list for each user in the app and then send an email to that list each time that user posts new content. However, it appears that the MailChimp API intentionally doesn't support creating campaign lists via the API (for CAN-SPAM reasons). I've read something about list segmentation in MailChimp, but I don't think that helps me with this situation. I'm curious if anyone else has run into a similar requirement to mine and how they dealt with it. Any insights would be most appreciated! Thanks.

• jquery.ajax multiple data problem

  - by Guillaume P

  Hi, I've been trying to make this code work for the last 3 hours. I've tried about everytinh, but I'm still unable to get it to work. I only managed to send 1 data. When I use this code, I only manage to retrieve recaptcha_challenge_field. If I remove recaptcha_challenge_field, I retrieve recaptcha_response_field. However, I am unable to retrieve the two at the same time. challengeField = $("#recaptcha_challenge_field").val(); responseField = $("#recaptcha_response_field").val(); var html = $.ajax( { global: false, type: "POST", async: false, dataType: "html", data: "recaptcha_response_field=" + responseField + "&recaptcha_challenge_field=" + challengeField, url: "../ajax.recaptcha.php" }).responseText; if(html == "success") { $("#captchaStatus").html("Success. Submitting form."); return true; } else { $("#captchaStatus").html("Your captcha is incorrect. Please try again"); Recaptcha.reload(); return false; }

• Problem with istringstream in C++

  - by helixed

  Hello, I'm sure I'm just doing something stupid here, but I can't quite figure out what it is. When I try to run this code: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("hello"); istringstream input(s, istringstream::in); string s2; input >> s2; cout << s; } I get this error: malloc: *** error for object 0x100016200: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug The only thing I can think of is that I allocated s2 on the stack, but I thought strings manage their own content on the heap. Any help here would be appreciated. Thanks, helixed

• Sending message from working non-gui thread to the main window

  - by bartek

  I'm using WinApi. Is SendMessage/PostMessage a good, thread safe method of communicating with the main window? Suppose, the working thread is creating a bitmap, that must be displayed on the screen. The working thread allocates a bitmap, sends a message with a pointer to this bitmap and waits until GUI thread processes it (for example using SendMessage). The working thread shares no data with other threads. Am I running into troubles with such design? Are there any other possibilities that do not introduce thread synchronizing, locking etc. ?

• managing library dependencies with Boost.Build and C++

  - by user931794

  I want to develop a project which can be built on a bunch of different platforms. The project code will be in C++, what's the the best way to manage libraries? I plan on using bjam as the build system because I'm going to be depending on Boost and their unit testing framework as well. The two dependent libraries are Boost itself and FLTK. The possibilities that come to mind for library management are: include build artifacts (binaries) and headers for all supported platforms in-tree include complete source for all dependent libraries in-tree, and somehow script them as dependencies A combination of 1 and 2, like node.js does with v8 inform the user that they need to build the libraries themselves and then have them on the PATH or in some special directory, like libcurl does with its dependencies What is the best approach here? The project will probably not grow beyond a few thousand lines over the next six months, but I want to make the right choice here so that I don't have to come back and switch everything around later.

• .NET 4.0 build issues on CI Server

  - by DMcKenna

  Anybody manage to get .net 4.0 applications compiling on a CI server without installing visual studio 2010 on a CI server. No SDK exists for .net 4.0. Have installed .NET 4.0 on CI Server. Msbuild.exe works for simple projects and give the following warning (GetReferenceAssemblyPaths target) - C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(847,9): warning MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.0" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in placeof reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.

• How do I use NTLM authentication with Active Directory

  - by Jon Works

  I am trying to implement NTLM authentication on one of our internal sites and everything is working. The one piece of the puzzle I do not have is how to take the information from NTLM and authenticate with Active Directory. There is a good description of NTLM and the encryption used for the passwords, which I used to implement this, but I am not sure of how to verify if the user's password is valid. I am using Coldfusion but a solution to this problem can be in any language (Java, Python, PHP, etc). Edit: I am using Coldfusion on Redhat Enterprise Linux. Unfortunately we cannot use IIS to manage this and instead have to write or use a 3rd party tool for this.

• Django : proper way to use model, duplicates!

  - by llazzaro

  Hello, I have a question about the proper, best way to manage the model. I am relative newbie to django, so I think I need to read more docs, tutorials,etc (suggestions for this would be cool!). Anyway, this is my question : I have a python web crawler, that is "connected" with django model. Crawling is done once a day, so its really common to find "duplicates". To avoid duplicates I do this : cars = Car.Objects.filter(name=crawledItem['name']) if len(cars) 0: #object already exists, update it car = cars[0] else: car = Car() #some non-relevant code here car.save() I want to know, if this is the proper/correct way to do it or its any "automatic" way to do it. Its possible to put the logic inside the Car() constructor also, should I do that? Thanks a lot!
