  • Explain DLL Dependencies to a lay person

    - by wheaties
    This follows from a previous posting I made about lack of a clean test machine for software installations. I'm doing a bad job of explaining how DLL dependencies work and how some machines might not have the right libraries at the time of installation. The problem is that it's being viewed as a defect with the build process. I'm trying to educate the higher ups that it's not the build process per se but rather the installation process which is to blame. Here's a quote from my boss relating subcontractor work to our work to put it into perspective: I'm not a software person. All I see is that when they hand something to us it just works but when we hand something to the client there's all sorts of problems. There must be something wrong with how you're building the code. It's very easy to see how someone who is smart (scarily smart) could come to the wrong conclusion. So how would you explain the whole DLL dependency issue?

  • PHP e-commerce site talking to internal database for stock / ordering?

    - by CitrusTree
    Hi. I'm working on an e-commerce site (either bespoke with PHP, or using Drupal/Ubercart), and I'd like to investigate the site interacting with an internal (filemaker) database we use to manage stock and orders. Currently we manually transfer orders from the web site to our own database, and the site does not check or record changes in stock. My plan to allow the 2 to interact is as follows: Make the internal database available externaly on a machine with a fixed IP Allow external access from the site only Connect to the internal database using ODBC (or similar) Use simple queries to check stock / record stock changes / record order details Am I missing something here as this sounds quite straight forward? Is there another solution I should be taking a look at? Thanks in advance for any help or comments.

  • Platform Framework and Middle-ware

    - by Walidix
    I really want to fix the meanings of this terms.This is what I know about them: Platform: is an environment that allows an application to run and it is usually composite by hardware and software e.g. your machine with your OS installed on it. However some software stack are also called as platform like Java Platform. Framework: is design-oriented. That is, it defines a skeleton of an application type. Also it saves time by offering, through an API, the common functionalities that a kind of applications must implement. Moreover a Framework include a software components that manage the application life-cycle. Middle-ware: is a software that offers services to an application in order to let it inter-operates with other applications or supports different platforms. Middle-ware can be a part of a framework. Is there something wrong or missing ?

  • Console Utility that can remote connect to other systems and issue commands

    - by vivekeviv
    Hi Frequenlty my work involves to VNC to a remote system and work on it. SInce i run command line apps on this remote system most of the time, i was wondering if there's an alternative software to command prompt which i could install on my local machine. Using this i should be able to create a session with the remote system and from then on all commands issued in command prompt should run in remote system. localHostdir -- should list the directory contents in remotehost active directory localhostapp.exe should run app.exe in remote host and display its contents in localhost command prompt I browsed a little and read about cmdlets in powershell. But it looks like i need to write a cmdlet for each app in the path (dir, mkdir, app.exe in the path). Correct me if am wrong. Once session is established, i simply need the commands invoked in local host to be run in the remote host and return the console output to local host. Please let me know if powershell + cmdlets are the only way THanks

  • VB.NET: Can the .EXE built by VS2005 be deployed as a standalone EXE?

    - by Craig Johnston
    VB.NET: Can the .EXE built by VS2005 be deployed as a standalone EXE? When I change the mode in VS2005 to "Release" and build the solution, the bin\Release directory then contains the solution .EXE file, but also a .pdb, vshost.exe and .xml file. What are these extra files and are they necessary? I copied the .exe file to another machine and it executed properly, but there was a significant delay when it first executed - thereafter it was like any other program. What is the reason for this, and can it be helped? Is it because the other 3 files in the Release folder are not there with it?

  • Minimum requirements to use Indefero + SVN

    - by Gnucom
    Hey everyone, I made sure there wasn't a similar discussion before posting but forgive me if I am mistaken. Question: Can I use Indefero - http://www.indefero.net/ - with SVN on a linux server if I do not have any sort of web interface installed for Apache? Instead, I want to use Indefero with SVN by just using the svnserve server. From my readings, I'm not finding this exact situation mentioned anywhere, so I'm doubting if this configuration is possible. Forgive my ignorance; Thanks. :) EDIT: the svnserve server and Indefero installation will be running on the same machine.

  • Jquery .Ajax error when trying to POST data in ASP.NET MVC

    - by GB
    I am unable to access an action in my controller using .ajax. The code works on my development machine but as soon as I place it on the server it gives the error 401 Unauthorized. Here is a snippet of the code in the .aspx file... var encoded = $.toJSON(courseItem); $.ajax({ url: '<%= Url.Action("ViewCourseByID", "Home") %>/', type: "POST", dataType: 'json', data: encoded, //contentType: "application/json; charset=utf-8", success: function(result) { Update: The only time this doesn't work is when I pass json data to the Ajax call, it works fine with HTML data.

  • keep open windows console after a python syntax error

    - by basweber
    File associations on my machine (winxp home) are such that a python script is directly opened with the python interpreter. If I double click on a python script a console window runs and every thing is fine - as long as there is no syntax error in the script. In that case the console window opens up for a moment but it is closed immediately. Too fast to read the error message. Of course their would be the possibility to manually open a console window and to execute the script by typing python myscript.py but I am sure that there is a more convenient (i.e. "double click based") solution.

  • Custom URL protocol in Windows to serve HTML content

    - by Jen
    This question addresses how to register a custom URL protocol to launch an application in response to a link, but I want my handler to serve dynamic content. Essentially, I'm looking to create a web application that runs on the user's machine instead of a web server. I could set up a localhost, but I want to use a "friendly" URL format that the user can reference elsewhere, e.g. a hypothetical cats protocol: cats:fluffy/cheeseburger-consumption-stats How can I accomplish this? Also, do you see any pitfalls with this approach, such as security warnings from browsers? Thanks!

  • how much concurrent http request can erlang handle

    - by user209123
    I am developing a application for benchmarking purposes, for which I require to create large number of http connection in a short time, I created a program in java to test how much threads is java able to create, it turns out in my 2GB single core machine, the limit is variable between 5000 and 6000 with 1 GB of memory given to JVM after which it hits outofmemoryerror with heap limit reached. It is suggested around that erlang will be able to generate much more concurrent processes, I am willing to learn erlang if it is capable of solving the problem , although I am interested in knowing can erlang be able to say generate somewhere around 100000 processes which are essentially http requests waiting for responses, in a matter of few seconds without reaching any limit like memory error etc.,

  • How do I determine if my R installation on OS X has the "--enable-R-shlib" option enabled?

    - by Milktrader
    I've installed R on my OS X machine via the .pkg method. I'm trying to get a Ruby gem called RSRuby to work and though it installed correctly, it's throwing an error when I try to invoke the gem. Fatal error: R home directory is not defined Reading the documentation, R should be installed with the option --enable-R-shlib. But the R documentation states that the Mac OS X installation does this by default. How can you verify that this option is enabled on an installation if you don't know it was explicitly called during installation? I'm chasing down why RSRuby can't find R home directory and this seems like the most likely problem.

  • Why is it supposedly "hard" to deploy Ruby on Rails to production?

    - by johnny
    I admit that I don't follow much of anything "right" on deploying test versus production code. I have been using ASP.NET, and I typically run it locally in Visual Studio, it works, I upload it, I test it again on the production server. I have read several people say that deploying Rails apps is harder and there are special programs/ways on the ruby site about deploying RoR. I've only toyed with RoR. What is special about deployment? You don't just copy and paste the code and run it (from development machine to the production)? Is it because one is in Apache and the other running on the built in server? This will be on a Mac Server if it matters. Thank you for comments.

  • "SQL Server does not exist or access denied." upon VB.Net Deployment

    - by JasonMHirst
    Have built a small VB.Net app in VS2010. The connection string to the SQL Server is as follows: <connectionStrings> <add name="IWSR_DataDownloadWizard.My.MySettings.sqlConnection" connectionString="Provider=SQLOLEDB.1;Data Source=SQLServer;Integrated Security=SSPI;Initial Catalog=IWSROL" providerName="System.Data.OleDb" /> </connectionStrings> Within the VS2010 environment AND on my machine, the connection works perfectly, however when I deploy to clients I get an error message of: [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. I've tried to search the net for solutions, have seen a few instances of people saying to NOT use the Server Name but the IP Address instead (this doesn't work) and some saying to remove the "Provider=SQLOLEDB.1", again this doesn't work. Can anyone suggest a solution please? Further information: Development System is Windows7 using VS2010 Deployment systems are a combination of Windows XP, Windows 2000 and Windows 7 SQL Server is SQL2000 (soon to be SQL2005). TIA

  • Cannot execute cut-n-paste VBScripts

    - by IcedDante
    I have been going mad trying to figure out why my scripts weren't working, until I started copying and pasting sample source code directly from a few websites only to have it fail there as well. I am getting the following error in my VBScripts: C:\temp\vbs\script.vbs(19, 53) Microsoft VBScript compilation error: Expected statement' For a line of code that looks like this: wdoc.Application.Selection.Find.Execute Replace:=wdReplaceAll This is interfacing with Microsft Word in Office 2007 to conduct a search and replace. Index 53 point directly to the := part of the assignment. Since this type of syntax doesn't work on my machine and I am using it from several websites, I was wondering if the cscript.exe I use is out of date. Am I not calling cscript properly?

  • Finding final/effective web.config values (from inherited configurations)

    - by gregmac
    Are there any apps that can show the final configuration as applied to a particular application directory? What I'm picturing is something along the lines of FireBug's CSS viewer. Basically, it should show the equivalent single web.config file (as if you only had one), with all the values that apply to the directory in question, with each element (or even attribute) annotated with its source (the real .config file it came from). This would greatly help deploying applications into foreign environments (eg, customer sites) where they sometimes have strange configs, that add in global includes (eg, they put the include in machine.config, instead of the web.config for that app) or have allowOverride=false, etc.

  • Flex Builder 3 executing old source codes

    - by Gorro
    I'm facing this problem again and again, but can't find any solution (except mine, which is not as a good one I guess). Don't know why, sometimes Flex Builder executes old source codes after making changes. While debugging I see how it steps through a source (e.g. changing local variables) which does not exist (even if I delete all that block or function). My way to solve that is to delete the project (backing up the source codes of course) and create a new one, add the backed up sources to the project and rebuild. It starts to work as it should work, but this way is not as comfortable, especially if sources are on a remote machine and you need to configure .net back-end. Anyone knows how to solve?

  • Turn off the display on remote PC

    - by concretemixer
    Hello. I'm fixing some bugs in the application for remote control (remote desktop-like) for Windows. And there is a feature that you can blank screen on remote machine - all the programms keep running unaffected, but the person who looks into the display on remote PC sees nothing but black screen. It is implemented by sending IoCtl request IOCTL_VIDEO_SET_OUTPUT_DEVICE_POWER_STATE, which is undocumented. And this request does not work on Vista and above. Are there another ways to do what I want? In fact, SendMessage(-1,WM_SOMMAND,SC_MONITORPOWER,2) does the trick, but screen turns back on if someone toches keyboard/mouse.

  • Fastest way to deploy rails apps with Passenger

    - by yuval
    I am working on a Dreamhost server with Rails 2.3.5. Every time I make changes to a site, I have to ssh into the site, remove all the files, upload a zip file containing all the new files for the site, unzip that file, migrate the database, and go. Something tells me there's a faster way to deploy rails apps. I am using mac Time Machine to keep track of different versions of my applications. I know git tracks files, but I don't really know how to work with it to deploy my applications, since passenger takes care of all the magic for me. What would be a faster way to deploy my applications (and avoid the downtime associated with my method when I delete all files on the server)? Thanks!

  • Calling a web service from a windows service

    - by Arun
    I'm sure there's an elegant solution to the problem but I just can't get my head around it. I am trying to call a web service from within a Windows service. The web service is secured (using Windows authentication). The account that the windows service runs under does have the rights to call the web service but I can't figure out how to get those credentials and send them off to the web service. The web service is WCF and is hosted on the same machine (in IIS) as the windows service.

  • Automatic upload of 10KB file to web service?

    - by Joseph Turian
    I am writing an application, similar to Seti@Home, that allows users to run processing on their home machine, and then upload the result to the central server. However, the final result is maybe a 10K binary file. (Processing to achieve this output is several hours.) What is the simplest reliable automatic method to upload this file to the central server? What do I need to do server-side to prevent blocking? Perhaps having the client send mail is simple and reliable? NB the client program is currently written in Python, if that matters.

  • Installing Ruby on Rails in Fresh Ubuntu 10.10 System

    - by Benedict Aluan
    There are a lot of tutorials on how to install Ruby on Rails in Ubuntu 10.10. But even following the steps, there are still errors and dependencies that will encountered in order to successfully install RoR. The system varies on the developer's setup. To make it uniform, installation must be on a fresh Ubuntu 10.10 system. Is there a step-by-step guide on how to install RoR on a Fresh Ubuntu 10.10 machine? Like the first thing I need to do after starting the terminal.

  • Windows Workflows - While Activity for creating multiple tasks not working

    - by Georgil Mathew
    I am using a while activity for creating multiple tasks for a workflow. The code is executed fine and the task is created when the loop runs only once. But when the loop runs twice or more, only one task is getting created. Also the WF status shows as Error Occured. All I want to do here is create multiple tasks (no of tasks depends on an entered column value) for the same user. Is it posible to use 'while' in this scenario? Or is there any other way to go ahead? NB: I am using state machine workflow.

  • Proper way to have an endless worker thread?

    - by Neil N
    I have an object that requires a lot of initialization (1-2 seconds on a beefy machine). Though once it is initialized it only takes about 20 miliseconds to do a typical "job" In order to prevent it from being re-initialized every time an app wants to use it (which could be 50 times a second or not at all for minutes in typical usage), I decided to give it a job que, and have it run on its own thread, checking to see if there is any work for it in the que. However I'm not entirely sure how to make a thread that runs indefinetly with or without work. Here's what I have so far, any critique is welcomed private void DoWork() { while (true) { if (JobQue.Count > 0) { // do work on JobQue.Pop() } else { System.Threading.Thread.Sleep(50); } } } After thought: I was thinking I may need to kill this thread gracefully insead of letting it run forever, so I think I will add a Job type that tells the thread to end. Any thoughts on how to end a thread like this also appreciated.

  • Time order of messages

    - by Aiden Bell
    Read (skimmed enough to get coding) through Erlang Programming and Programming Erlang. One question, which is as simple as it sounds: If you have a process Pid1 on machine m1 and a billion million messages are sent to Pid1, are messages handled in parallel by that process (I get the impression no) and(answered below) is there any guarantee of order when processing messages? ie. Received in order sent? If so, how is clock skew handled in high traffic situations for ordering? Coming from the whole C/Thread pools/Shared State background ... I want to get this concrete. I understand distributing an application, but want to ensure the 'raw bones' are what I expect before building processes and distributing workload. Also, am I right in thinking the whole world is currently flicking through Erlang texts ;)

  • Rails - Permission denied when try to save uploaded file in windows

    - by logoin
    I'm writing my own file upload in rails. I saw some related questions but it doesn't answer my question. I use File.open ("#{RAILS_ROOT}/public/docs/attachments/#{@file_name}", "wb") {|f| f.write(@temp_file.read)} to write the file on my local machine (OS: Windows XP) instead of saving it in database. I got a Permission denied error on the File.open method. Since I have cygwin installed, I chmod 777 the folder that files should write to and also make sure the file I upload can be read. But I'm still getting the same error. Any ideas? Thanks!
