• transfer files with ftp with ftpwebrequest

  - by Dejan.S

  Hi. currently I'm working on this ftp transfer. http://msdn.microsoft.com/en-us/library/ms229715.aspx I have setup my server computers iis to have a ftp site on port 21 and transfering files works great. But I want to add ftp to a hosted site I got on the server and it's here where I get the problems with connecting. when I try to connect through the command promt I get unknown host error. I have changed the port and open it up in firewall. and even if I could connect how can I decide what folder I want to upload to?

• sscanf + c99 not working on some platforms ?

  - by Jane

  When I compile a simple Hello World! program that uses the sscanf function on my local Debian lenny x64, it works. But when I upload the same program to the server running CentOS x86, it will not work. If I do not use sscanf, then the program works on both computers. gcc -std=c99 -O2 -pipe -m32 If I compile it with sscanf but without -std=c99, then it works on both computers. gcc -O2 -pipe -m32 What is the problem with sscanf and c99 on CentOS x86 ? I thought that compiling with the -m32 flag would work on all Linuxes ? (I have limited access to the CentOS server, so I do not have access to error messages.)

• Create and access folder outside Apache Tomcat webapps folder

  - by Padur

  My web application requires functionality where end users can upload content, that can be later downloaded or viewed by others, the problem with current scheme is If I create such folder as part of your web project under webapps, every time I do deploy your web application (*.war), the content of that directory will be lost (or overridden). I think the best way to accomplish that is to create folder outside of standard tomcat webapps and access it from there, not sure how to do. Please point in correct direction. I am using Tomcat 4.x soon will be moving to 6.x. -Padur

• Choose a local file w/o uploading the chosen file

  - by Austin Hyde

  I am making a simple development tool for myself using PHP on my local development server. I would like a way to have a simple file-chooser to select a file without uploading it, but just retaining the file path. This is useful, because I will be the only one using the tool, and so PHP will have access to the chosen file without having it uploaded. My first thought is to have a <input type="file"...>, but as far as I know, there's no way to prevent the upload from happening. Is there a way to do this?

• Display a "Waiting Menssage" before the POST form send

  - by DomingoSL

  I have a upload file form, when you hit Submit it send the file to my server, but it takes a while, in the mean time i need to tell the user wait in order to get the file uploaded, because he can press Submit again because there is no menssage to prevent him. So, the user fill a few fields in the form, including a file. When he Send the form it sends the variables via POST to the same page: <form action="<?php echo $_SERVER['PHP_SELF']; ?>" enctype="multipart/form-data" method="post"> A php script detect the page now have POST variables a do something. In the time between the send action and the page reload i need to display a mensage, how can i do that??? Thanks It will be nice if you now how to trigger that with colorbox. I know how to use it from a link but no from this POST action.

• File version maintainence via PHP FTP?

  - by Michael

  Currently I'm working on a "plugin" that will be installed on many different sites and I was wondering on the best way for me to maintain the file version of this "plugin". Here's what I was thinking. Have a "master copy" of the plugin on a server, then connect via FTP to the target sites and upload the copy to their site overwriting whatever files they may have. I was wondering the best way to go about this. The "plugin" will have many different folders and files so transferring one file at a time will be too tedious. Is there a way to copy an entire folder over at a time? Or even better, is there a way to recurse through the folders and checking for file difference before uploading the new file? This is to make sure we are uploading a new file and not just the same one.

• Attachment_fu error

  - by cswebgrl

  Hello, I am getting an error while trying to upload images on an Ubuntu machine that's running Rails 2.3.4, Ruby 1.8.6 using attachment_fu with image science. FreeImage exception for type ???: IPTC: Invalid key 'Tag 0x025C' The error seems to point to this line in the image_science_processor in the attachment_fu plugin: def with_image(file, &block) ::ImageScience.with_image file, &block end My initial thoughts are that it has something to do with meta tags and the images and maybe free image. I don't actually see this error on my dev machine - Mac Snow Leopard, Rails 2.3.5, Ruby 1.8.7. Before I start messing versions on the production boxes, has anyone else encountered this issue and have an idea to fix it? THANKS!!!!

• What is the best way to read the uploaded files from Request.Files, StreamReader or BinaryReader or

  - by ramesh.nagul

  I have a form where the user can upload multiple files. I am using MVC 2.0 and in my controller I need to call a webservice that is a common import interface requires the files to passed in as byte[]. .NET exposes Request.Files as a HttpFileCollectionBase and I access the filehandle using HttpPostedFile or HttpPostedFileBase that provides access to the Stream member. What is the best way for me to read the bytes from the stream? BinaryReader? StreamReader? BufferedStream?

• How to handle HTTPStatus Response 201 with AS3 / Flash / SWFUpload

  - by Praveen Sharma

  Hey all. I'm using SWFUpload on a Rails site to allow for MP3 Uploads direct to Sound Cloud. To avoid having to first upload a large file to my server and push to Sound Cloud, I'm hitting their API directly via SWFUpload, passing necessary OAuth token data. Everything works - EXCEPT - Flash can't handle the HTTP response code that Sound Cloud's API returns (201). This ALWAYS triggers an unhandled IO Error with Flash. Even though SWFUpload allows me to override that in the JS, it breaks any response data (the URI to the uploaded file). Does anyone know how I could somehow intercept the 201 code so that I can make it a 200 code for flash? I'm at a loss at how I can avoid this IO Error. I've tried try/catch statements around everything and have even recompiled SWFUpload to try new things to no avail. Any help would be greatly appreciated.

• Access SDExplorer (System Folder) from my C# app

  - by Søren

  Hello everyone I am trying out Windows Live SkyDrive, and I installed SDExplorer (http://www.cloudstorageexplorer.com/) It works by adding my SkyDrive folder to Windows Explorer, but it does not get a drive name or anything, so how can I access that drive/folder from my C# application? When I go into the folder and look at the address bar it says "Computer\SDExplorer". Directory.GetDirectories(@"\Computer\SDExplorer") does not work, because it translates to "C:\Computer\SDExplorer". I would like to be able to create a small application that can create folders and upload files to my SkyDrive account. Anybody know how these special folder/drives work? - I noticed MozyHome appears in the same way in my Windows Explorer.

• Drupal Background Image as Block or Node

  - by Marcy Sutton

  Hi There. I am having trouble wrapping my head around how to make editable background images in my custom Drupal 6 theme. My client wants to have a different background image for each main section (which use multiple content types: page, blog, image gallery)... I am wondering, is there a way to make a custom content type into a dynamic background image block? I am using the Image, Image Cache, Views, CCK, Image Assist, Panels, Filefield, and Imagefield modules. What I'd like to do is add a background image field to various content types that allows a user to reference an image from the content library or upload a new image (similar to ImageAssist), and have it apply to a region in my template. Any suggestions on the best approach for this? Thank you!

• How to check a SQL database table to see if a record exists

  - by Anthony

  I have a SQL database that creates a record for every document uploaded by the user to the server. I want to check this table before a user uploads a document to ensure they don't upload a file with name that already exists. I know how to make the connection and make the SqlCommand to query the table for an existing record. But I don't know how to check the record count from the sqlCommand I made. Does that make sense? Using myConnectionCheck As New SqlConnection(myConnectionStringCheck) Dim myCommandCheck As New SqlCommand() myCommandCheck.Connection = myConnectionCheck myCommandCheck.CommandText = "SELECT * FROM Req_Docs WHERE Doc_Name =" & DocName myConnectionCheck.Open() myCommandCheck.ExecuteNonQuery() End Using Thanks in advance, Anthony

• Can't get max_post_size php variable set in lunar pages.

  - by Behrooz Karjooravary

  I need to increase max post size and upload size for php to use the audio module of drupal. I read this has to be set in php.ini. However I don't think I have access to that file in lunar pages. I also read it can also be set in .htaccess. However it doesn't change anything. I tried: php_value post_max_size "40M" php_value upload_max_filesize "40M" i also tried: php_value post_max_size 40M php_value upload_max_filesize 40M On localhost it says restart webserver. But this is not possible on shared host. Could that be the problem?

• cakephp VS codeigniter VS zend framework

  - by i need help

  Very possibly very related: What PHP framework would you choose for a new application and why? Zend or CakePHP? Which one is better? Some people say CakePHP is better for php 4, what do you think? In my case, I would like the following: Lesser code to write, have really strong library and plugin base. Always have new library etc added in from contributor, eg: google map and etc... Ability to use together with the templating system like smarty. Have ACL that can control all the permission level issue. Load class when needed, unload when not needed. Load class once and use globally. Can run in windows environment (I am using xampp to run my php in windows.) After the site done, I will upload all codes into windows 2008 server (using php 5)

• ASP.NET FileUpload

  - by John

  Greetings! I am using the ASP.NET FileUpload control to allow users to upload text files to our web server. Everything works great in terms of saving the file to where we wanted, etc, using the SaveAs() method of the control. But we were caught off guard by one seemingly simple caveat: the original timestamp of the uploaded file was lost such as the date last modified and date create. The date last modified and date created become the actual date and time when the file is saved to the server. My question is: is there anyway to retain the original timestamp by setting some attributes that I am not aware of yet or is it possible to read the metadata of the file to get its original time stamp? Any in-sight and suggestions are greatly appreciated. John

• Image Uploading - security issues

  - by TenaciousImpy

  Hi, I'm developing an ASP.NET Web app and would like the user to be able to either upload an image from their local system, or pass in a URL to an image. The image can either be a JPG or PNG. What security issues should I be concerned about doing this? I've seen various ways of embedding code within JPG files. Are there any methods in C# (or external libraries) which can confirm that a file is a JPG/PNG, otherwise throw an error? At the very least, I'm making the directory which holds uploaded images non-browsable and putting a max size limit of 1mb, but I'd like to implement further checks. Thanks for any advice.

• OpenCV SVD Matrix format.

  - by Rick

  I currently have a set of 2D Cartesian coordinates e.g. {(1,3), (2,2), (3,4)} Which will be put into a 2D array, to perform SVD properly would the matrix be put together such that the coordinates form the columns or the rows e.g. 1 3 2 2 3 4 or 1 2 3 3 2 4 I have been doing a little trial and error comparing to examples of SVD I have found online, the resulting matrix usually seems to be negated, with some of the values shuffled around. To clarify further if I had a matrix E which was MxN as shown here http://upload.wikimedia.org/wikipedia/commons/b/bb/Matrix.svg To define the matrix as a 2D array would it be Array[M][N] or Array[N][M] I am assuming this actually matters due to matrix arithmetic not being commutative? Can anyone actually verify this?

• Running tasks in the background with lower CPU priority

  - by Brendon Muir

  I have a feature in my CMS that allows a user to upload a zip file full of images and the server will extract them and insert each one into an image gallery. I've noticed that this grinds up the CPU quite severely and causes other requests to slow down. I'm thinking of using the delayed_job plugin to delegate each image addition into the background, but I also want to give that process a lower CPU priority so that it doesn't bog down the server. I'm pretty confident in the delaying part of the exercise, but the throttling part is where I'm stuck. Is there a ruby way of lowering the priority of a method call? It's the image resizing that causes the CPU chew. Any ideas welcome :)

• How do I serve nested static content on Heroku?

  - by Matthew Murdoch

  I have a rails application with static content in the public directory (e.g. public/index.html) and additional static content in nested subdirectories (e.g. public/one/two/index.html). All the static content is served correctly if I run it locally via script/server but when I upload it to Heroku the top-level page loads correctly but the nested content returns a 404. I've found a number of resources (for example this question) which discuss static content in rails but they all seem to assume a fairly simple structure with a single directory containing all the files. Is there any way I can fix this?

• Detecting a image 404 in javascript.

  - by xal

  After a user uploads a file we have to do some additional processing with the images such as resizing and upload to S3. This can take up to 10 extra seconds. Obviously we do this in a background. However, we want to show the user the result page immediately and simply show spinners in place until the images arrive in their permanent home on s3. I'm looking for a way to detect that a certain image failed to load correctly (404) in a cross browser way. If that happens, we want to use JS to show a spinner in it's place and reload the image every few seconds until it can be successfully loaded from s3.

• Nexus: removing repository

  - by David

  Hi, I accidently removed a hosted snapshot repository from Nexus containing a few artifacts needed by other developers on my team. Fine, I'll be able to recreate it fairly easy, but when I tried to add the repository again with the same name as the one I removed, the "Upload Artifact" tab did not show. I tried to clean the cache and reindex the public and public snapshot repos, but that didn't help. I also tried setting an alternative storage path by entering an alternative path on "Override Local Storage Location", same result. Will I have to create a brand new repository with a different name and change all repository reference in my projects? Thanks, David
