Hello everyone!

I am using Salesforce Community to develop a mobile application. I want to store files (file feeds) into Amazon S3 instead of Salesforce. Does anyone know how to do that? Any help would be much appreciated.

I want to upload large files to S3 server from visualforce page. How can we achieve this? Now I am able to upload small files. Any help?

Hi,

 We have around 1000's of uploads done over the course of years and reaching our limit on storage. I can download the file but one file at a time is not a solution production wise. Please could you recommend on how to achieve downloading/exporting the pdf's to computer in a bulk method. 

 

Thanks.

Our users need to download multiple ContentDocument files, based on queries of related metadata (custom object) and/or file content (ContentVersion). 

 

And there could be 100s of such files that they want to download to their local computer based on one query....

 

We're replacing a  legacy system with SF, and that legacy system allows users to build such queries resulting in hundreds of files.  The legacy system then combines the files (along with a few standard report pages of the associated metadata) into a single (BIG) .PDF file which they then download to their local computer and print (or not) - so clicking hundreds of individual download links, giving a location/name for each file, would be quite tedious.  Users generally burn CDs with the PDF file - they don't normally print this much paper.

 

Any suggestions on how to do this, or something reasonably equivalent, in SF / VF?  

 

By the way, the users have Adobe Professional on their local computer, so if we could just get the files from SF into a single folder (or combine the file(s) into a single file or two) the users could then use Adobe to build their own PDF locally - I'm really interested in automating the download of ContentDocument file(s)  if at all possible...

Hi,

 

We have a process where customers need to submitted / upload scanned documents via a force.com app

Is it possible to store the documents externally via Google Docs OR Amazon S3 services?

 

There will be 100's of jpg scanned docs per week uploaded via the application.

 

Appreciate any advise on best practice.

 

Many thanks

Matt

Hi All,

 

We are using Amazon s3 as storage server to upload files from salesforce.It is working fine.

But some clients are facing issues with file upload/download due to their proxy restrictions.So the user who is uploading

the file is clueless about what went wrong.To handle this, I am trying to connect to https://s3.amazonaws.com

using XMLHttpRequest in Java script.If the request fails, I am displaying that "Unable to connect to

https://s3.amazonaws.com. Reason: Proxy Restriction".

XMLHttpRequest is failing because of cross domain problem.Can anyone guide me through this.Does anyone have

better approach?

 

Thanks

Gops
