  • Using PHP, can I put variables inside of variables?

    - by Rob
    For example, take this code: $ch = curl_init($resultSet['url']."?get0=get0&get1=".$get1."&get2=".$get2."&get3=".$get3); This of course, looks very ugly, and kind of a pain in the ass to read. So my question is, would I be able to use something like this: $allgets ="?act=phptools&host=".$host."&time=".$duration."&port=".$port; $ch = curl_init($resultSet['url'] . $allgets); Very simple question I suppose, but my server is undergoing maintenance, so I can't upload it and test it myself. I suppose a yes or no answer will suffice, but if you have a more efficient way of doing this, that would be even better. :)

  • Compile C++ program on Mac to run on Linux

    - by mav
    I have an application that I wrote in C++/SDL, using FMOD library. The app is portable and compiles without any code change on Mac and on Linux. But one annoyance is that when I want to ship Linux version, I have to run my Linux box, copy the source code over there (over USB drive, because I have no network there, it's an old laptop) and compile it, then copy it again over USB to my Mac and upload it. My question is - is there a better way of doing it? Ideally, could I compile the app to run on Linux directly from Xcode, where I compile it for Mac?

  • Web App fails when moved to production environment. Which server permissions do I need?

    - by Ashley Ward
    I have developed a small web app. This app allows users to upload images. It also produces text files with the names of those images (the names are stored and retrieved to/from an MySQL Database.) I have developed this app using MAMP. To create the uploaded image files I use the PHP function imagejpeg('my/path/name.jpg') and to delete the files I use the PHP function unlink('folder1/folder2/name.jpg') to write to the text document I am using the function fopen('folder1/folder2/name.txt', 'w') all three of these functions produce errors related to permissions - now the site has been moved to a live hosting environment. Why is this? and what permissions do I need to set the folder's folder1 and folder2 to? I know that permission 777 is generally bad because it opens up your server to the public. However what I have found is that the functions fail to work unless I use 777 on the folders. Can anyone shed any light on my dilemma?

  • MovieClip.onResize event? how?

    - by Phil
    I have a an swf, called 'controls' that I created with flash cs4. I upload the controls.swf to my web server. I create an application in flex and it loads the external swf controls into itself. So far I can manipulate the controls.swf via my flex app. I created a class in my external swf, but I need to add some onResize event/check to my scroll bar. For example, if my scrollbar size increases/decreases, I want it to change variable values. Is there some movieClip.onResize event?

    - by Nitz
    Hey guys How to make software work like torrent work? Bcz always when i see that torrent software then i am really amazed by their sizes and what they do in that sizes? How they managed the download by parts and then all together as soon as u downloaded full part? and as soon as you had great speed then your download speed automatically goes up?

Sorry i had asked many question. I know how downloading is happening means peer-to-peer all that.. but i don't know how they have built that kind of thing?

  • FileContentResult and international characters

    - by suzi167
    Hello, I am using a fileContentResult to render a file to the browser. It works well except that it throws an exception when the fileName contains international characters. I remember reading somewhere that this feature does not support international characters but I am sure there mustbe a workaround or a best practice people follow in cases the application needs to upload files in countries other than US. Does anyone know of such a practice?Here is the ActionResult Method public ActionResult GetFile(byte[] value, string fileName) { string fileExtension = Path.GetExtension(fileName); string contentType = GetContentType(fileExtension); //gets the content Type return File(value, contentType, fileName); } THanks in advance Susan

  • MYOB Service Sales Import

    - by sjw
    I have developed an export file from our Job Management system that I want to be able to import into MYOB Accounting Plus v18.5. The file is generated without issue and I have included every single field to make it easy for upload (i.e. Match All matches every field) The problem I am having is no matter what I do, I cannot get the sales to import... Every time, no matter what I do or how I create the customer card comes back with: Error -190: Customer not found. Sale invoice not imported. I have tried matching using - co./Last Name, Card ID & Record ID and every time I get the same error. I have created a single customer with a simply Co./Last Name, Card ID & Record ID and still, when I try to import using these same fields exactly matched, I get the same error...

  • How can I handle maxRequestLength exceptions elegantly?

    - by JMP
    In my ASP.NET MVC (v2 if it matters) app, I have a page that allows the user to upload a file. I've configured the maxRequestLength for my app to allow files up to 25MB. As a test, I send it a 500MB file which throws the exception: Maximum request length exceeded. (I only know this because ELMAH catches the error and logs it.) In my web.config, I've set customErrors mode="On" with a defaultRedirect, but the user isn't redirected at all, they don't even get a yellow-screen-of-death. In Chrome, for example, you'll see the error: Error 101 (net::ERR_CONNECTION_RESET): Unknown error. Is it possible to provide a more elegant user experience for this situation?

  • How can I set up jnlp for use with Sinatra?

    - by mmr
    I have a website currently running Sinatra and a bunch of other technologies. I wanted to get progress bars running, but that's been a no go. So, a friend of mine whipped up a quick upload in Java, and I'm running that through scponly (chrooted) to make sure they can't do anything funny with changing directories and suchlike. But how can I start the jnlp file from Sinatra? Is it as simply as making it a link and then letting it be downloaded by the user? This code suggests otherwise, but there are a lot of things in there I don't understand (probably because I'm not reading it in the context of the larger program there).

  • How to display some data differnetly than it is stored.

    - by Ben
    Hello, I seem to have a problem that I can't find a solution for. I have a table that has this format. projectId | departmentId | plan | ETC | month | year | ID But, I need to find a way to take that data and display it like this. Since this is my first time here I can't upload an image, but you can view it here. http://img85.imageshack.us/img85/8253/image004y.png Is this something a gridview can handle, or a repeater, or something else? Thank you. Ben

  • Storing uploaded content on a website

    - by Matt
    For the past 5 years, my typical solution for storing uploaded files (images, videos, documents, etc) was to throw everything into an "upload" folder and give it a unique name. I'm looking to refine my methods for storing uploaded content and I'm just wondering what other methods are used / preferred. I've considered storing each item in their own folder (folder name is the Id in the db) so I can preserve the uploaded file name. I've also considered uploading all media to a locked folder, then using a file handler, which you pass the Id of the file you want to download in the querystring, it would then read the file and send the bytes to the user. This is handy for checking access, and restricting bandwidth for users.

  • Continuous Deployment with a C#/ASP.NET website?

    - by Amber Shah
    I have a website in C#/ASP.NET that is currently in development. When we are in production, I would like to do releases frequently over the course of the day, as we fix bugs and add features (like this: http://toni.org/2010/05/19/in-praise-of-continuous-deployment-the-wordpress-com-story/). If you upload a new version of the site or even change a single file, it kicks out the users that are currently logged in and makes them start over any forms and such. Is there a secret to being able to do deployments without interfering with users for .NET sites?

  • Learning Algorithms and Data Structures Fundamentals

    - by valya
    Can you recommend me a book or (better!) a site with many hard problems and exercises about data structures? I'm already answering project Euler questions, but these questions are about interesting, but uncommon algorithms. I hardly used even a simple tree. Maybe there is a site with exercises like: hey, you need to calculate this: ... . Do it using a tree. Now do it using a zipper. Upload your C (Haskell, Lisp, even Pascal or Fortress go) solution. Oh, your solution is so slow! Self-education is very hard then you trying to learn very common, fundamental things. How can I help myself with them without attending to courses or whatever?

  • iPhone filesystem POSIX-compliant?

    - by Seva Alekseyev
    Hi all, I'm trying to pass some files from one app to another. I communicate the path (via a custom URL). The target application cannot read the file, citing errno 13 (permission denied). I've checked the permissions on file - they're 0644 (O+R), the permissions on directories all the way up to the root are 755 (O+RX). From a POSIX perspective, the file should be readable to any process and any user. Yet it's not. Any ideas, please? I can think of some workarounds. I could use a Web service (upload, get a cookie, communicate the cookie to the other app, other app downloads). I could also pass the actual file data in the URL - unelegant, and probably subject to length limitations. Clipboard is not supported on iPhone OS 2 IIRC.

  • memory usage in C# (.NET) app is very high, until I call System.GC.Collect()

    - by Chris Gray
    I've written an app that spins a few threads each of which read several MB of memory. Each thread then connects to the Internet and uploads the data. this occurs thousands of times and each upload takes some time I'm seeing a situation where (verified with windbg/sos and !dumpheap) that the Byte[] are not getting collected automatically, causing 100/150MB of memory to be reported in task manager if I call System.GC.Collect() i'm seeing a huge drop in memory, a drop of over 100MB I dont like calling System.GC.Collect() and my PC has tons of free memory. however if anyone looks at TaskManager they're going to be concerned, thinking my app is leaking horribly. tips?

  • How do you control the playback levels (decibles?) using the iPhone AVAudioPlayer? Or do I need to u

    - by Joshua
    My audio clips sound perfect when I upload them to the iPhone via iTunes. And I am pretty sure it is because the iPod has a maximum playback level, so the audio doesn't sound overdriven. In my app, I include the same audio files, and when I play them [myAudio play]; the levels are so high that the audio becomes indiscernible. I found in the library http://developer.apple.com/iphone/library/documentation/AVFoundation/Reference/AVAudioPlayerClassReference/Reference/Reference.html#//apple_ref/doc/uid/TP40008067-CH1-SW2 that it says that you can "Control relative playback level for each sound you are playing" but I've been searching this issue out for hours and I haven't gotten anywhere. Any help would be wonderful!

  • Export to Excel from dataset with out using htmltextwriter

    Export to Excel from dataset with out using htmltextwriter Hey, I'm having an issue occuring when I want to import data back into a table from a file. My export creates a file successfully as a .xls file. However, my contents for the file are being written as standard html table as seen below rather than the file content that normal excel files are saved in. The issue I have now is this. I need to take this file along with whatever changes or additions that were made by an end user and upload it back to a table in SQL Server. The error I get is: External table is not in the expected format.

  • Is SQL server the best DB for Storing and comparing images in database for a small ecommerce applica

    - by iecut
    I have been trying to create a small e-commerce web based application using MS Dot Net framework. The application will let the user allow to store the image of their product that they want to sell or purchase, then they will have the option to upload the image of a particular product and compare that image with the similar images in the database. So my two main concerns are: - Is MS SQL a good option to store and compare the images. - Is the any other better database that can do the same work with less complexity of work and that is also easy to integrate with MS dot net framework.

  • Problem w/ Paperclip, MacPorts, ImageMagick & Snow Leopard

    I'm attempting to use ImageMagick along w/ Paperclip to handle the images on my rails app. The problem is whenever I try to upload an image I get the following in the terminal: [paperclip] An error was received while processing: #<Paperclip::NotIdentifiedByImageMagickError: /var/folders/go/goZ833AaFaqyvv5RnLqQmE+++TM/-Tmp-/stream20110107-6356-1xfs9j1-0.jpg is not recognized by the 'identify' command.> I have added the following to my environments/development.rb file: Paperclip.options[:command_path] = "/usr/local/bin" If I try to interact w/ ImageMagick in the terminal by using "convert" or something similar I get: dyld: Library not loaded: /opt/local/lib/libltdl.7.dylib Referenced from: /usr/local/bin/convert Reason: Incompatible library version: convert requires version 10.0.0 or later, but libltdl.7.dylib provides version 9.0.0 Trace/BPT trap I've already tried updating everything w/ port but the problem still persists.

  • Django gives "I/O operation on closed file" error when reading from a saved ImageField

    - by Rob Osborne
    I have a model with two image fields, a source image and a thumbnail. When I update the new source image, save it and then try to read the source image to crop/scale it to a thumbnail I get an "I/O operation on closed file" error from PIL. If I update the source image, don't save the source image, and then try to read the source image to crop/scale, I get an "attempting to read from closed file" error from PIL. In both cases the source image is actually saved and available in later request/response loops. If I don't crop/scale in a single request/response loop but instead upload on one page and then crop/scale in another page this all works fine. This seems to be a cached buffer being reused some how, either by PIL or by the Django file storage. Any ideas on how to make an ImageField readable after saving?

  • Bulkloading schema less entities on Google App Engine

    - by Rahul
    The new bulkloader added into SDK 1.3.4 works great for models that have a schema. For models inheriting db.Expando (or loosely defined schemas) i would like to understand what i would have to do to bulk upload them. I defined a custom connector, that implemented the ConnectorInterface and converted my data to the python dict required. How can i use this dict to define entities that get uploaded to the data store ? In the documentation there seems to be a post_import_function that can be used to return the entities that get uploaded. Is there an example on how this function is used ?

  • Is it possible to take a screenshot of a web page with Javascript or HTML5/Canvas?

    - by Ryan Kearney
    Is there a way I could insert some code into a page that would take a screenshot of what the user sees in the browser window, then upload that image via a web form of some sort? I'm working on a clone of a pay-to-use service that lets you install a widget on a web page which in turn allows viewers to report bugs in the sites layout. Currently they use a Java applet to take the screenshot, which, in my opinion, is probably the worst way to go about it (aside from requiring the user to install a plugin) Is there a javascript/flash/other alternative? Thanks

  • Replacement for Azure SDK Powershell commandlets for deployments

    - by Frank Rosario
    Hi, We've run into an issue with the New-Deployment Azure Powershell commandlet timing out; we've put in a bug report with MS. While they gave us an explanation for it (the path and timeout threshold used to upload through commandlets is different then what's used by the web portal); they don't have a fix for us. We need to get this running so we can automate our build deployments, so we're looking into developing a custom commandlet to replace New-Deployment using the Azure SDK; hoping this path will not have the timeout issues the commandlet did. But before we go down that route; are there any other scriptable tools I can use to replace the New-Deployment functionality? I looked at Cloudberry for Windows Azure; but that doesn't have a scriptable interface yet. Any constructive input is greatly appreciated.

  • ASP.net error message when using REST starter kit

    - by jonhobbs
    Hi all, I've written some code using the REST starter kit and it works fine on my development machine. However, when I upload it to our server the page gives me the following error message... CS1684: Warning as Error: Reference to type 'System.Runtime.Serialization.Json.DataContractJsonSerializer' claims it is defined in 'c:\WINNT\assembly\GAC_MSIL\System.ServiceModel.Web\3.5.0.0__31bf3856ad364e35\System.ServiceModel.Web.dll', but it could not be found I've removed code line by line and it appears that the following line of code is triggering the error... HttpContent newOrganizationContent = HttpContentExtensions.CreateXmlSerializable(newOrganizationXml); Really haven't got a clue how to fix it. I assumed it might be because it needs a newer version of the framework to run, but looking in IIS it says it's running version 2.0.50727 which I think is the lates version because it says that even when we're using framework 3.5 Very confused, any ideas?
