We need to download multiple files from remote servers. It is a process that would take few hours to complete, since we are talking about images ~50kb each and more than 250.000 in total. Each images will downloaded, resized and then imported to SQL.DB, so we do not need to write files to the disk. Also the applications need to use network credentials, since it is behind ISA.
From your experience, what is the best method to implement this? Should we use WebClient or HttpSockets? Should we use Async methods or Threads ? How can we implement for example 5 simultaneously download to achieve better speed, since we may getting files from many different servers at once?

I have coded a routine that creates a series of excel files in a folder called "SaveExcelFiles". This routine works fine. What I now want to do is to create a routine that will let my user download (copy) the entire folder to his PC. I do not want to have the user have to download each excel file separately if this can be avoided. Also I would like to have a routine that deletes all of the excel files in the folder.

View 1 RepliesI have a web application that allows users to upload files which are stored in a database. Users can then search for files and click a link to download them. Clicking the link opens a new window which retrieves the file from the database and offers the user the chance to open the file or save it.
All of the users within our organisation use IE 6, yet while some can click a link and download the file, others can't. The new window simply opens for a split second, then closes. If it was all users I would think it might be the application, but as it is only some I am tempted to think it is a browser issue.

I creating a page where our clients can view advertising images and then able to download the images in different file formats. So I need the images and the different download types all saved into the same row in the database so that when I go to display them on the page when they select a picture the right download links will be there. So here where my problem comes in, I don't know how to code it so that I can insert mulitiple file paths into the database at once. The images are saved in a table called images. The downloads are saved in a table called Image Downloads.
Here is the code for the page I have it coded to submit the images to the database but not sure how to add the rest. I have got three different sql datasources for each table not sure if that's the way to go.

I have an application that uses resource files to display items in multiple languages. My app uses quote a lot of javascript and the alerts need to display in the local language. To do this, I have created an http handler which will read the keys and values of the culture-specific resource file and write them to a JSON array which is then embedded in the page in a script tag, the messages can then be accesses using, for exmaple:
Message.Error (en-GB = "Error", fr-FR = "Erreur")
The messages http handler works great in development, however when I run the application on a test server, I get the error: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Resources.Alerts.resources" was correctly embedded or linked into assembly "App_GlobalResources.b0n9j90e" at compile time, or that all the satellite assemblies required are loadable and fully signed. The code that I use to acccess the resource file is:
ResourceManager manager = Resources.Alerts.ResourceManager;
ResourceSet resourceSet= Resources.Alerts.ResourceManager.GetResourceSet(Thread.CurrentThread.CurrentCulture, true, true);
Where Resources.Alerts is the type that contains my multi-lingual definitions. The build action for the Alerts.resx file is set to "Embedded Resource". Any ideas why this works locally but not on my test server, am I missing something?
downloading files from an FTP server. The FTP server produces new files from time to time. so my application needs to Download only the "NEW" files and disregard what i have already downloaded previously. I have a time stamp on when was the last download time. I Using FtpWebRequest, WebRequestMethods.Ftp.ListDirectory, WebRequestMethods.Ftp.GetDateTimestamp. The problem is the ListDirectory gives me all the List in the FTP directory and i have to loop all the way down starting again from the start to the last file and check it with my last time stamp to DL the NEW files another problem is the FTP Directory contains 30,000 Files so it would take long until ill find the my last download time to start again on that point..
