Re: Uploading large files to SP 2010 - InfoPath limits and alternatives

Yes, I have. As written in the original post: "Although it is technically possible (incrementing user session data -to allow large files- and moving programmatically the attachment to a SP library -to don't blow up the form-), it seems like it is not recommended because of the performance impact on the farm [1]."

Basically, I have already tested that approach (just coding it, without using QRules) but that was not what I've asked in the post. (the point is not depending on user/form session data ...)

Anyway, thanks for your time! Perhaps someone else can bright some light here ;)

Have you already seen the answer here proposing to use QRules ?

Uploading large files to SP 2010 - InfoPath limits and alternatives

Hi there, anyone can give me his/her two cents?

Problem)

We have several complex InfoPath forms in production. Got a new requirement for one of them: Client needs to be able to upload large files to SP libraries using this IP form (as file attachments).

Caveat)

Although it is technically possible (incrementing user session data -to allow large files- and moving programmatically the attachment to a SP library -to don't blow up the form-), it seems like it is not recommended because of the performance impact on the farm [1].

Looking for solutions)

Thus, we are thinking about how can we manage this situation (leveraging the already designed InfoPath form). We have thought about several alternatives:

1) "Embedding" a FileUpload ASP.NET control within the form.

2) Simply put a link pointing to an ASP.NET page containing the FileUpload control.

Problems with the solutions)

1) I think it's not technically possible to upload files from InfoPath without using the user/form session storage (even if it were possible to embed the FileUpload control within the form).

2) Since we want to know if the user has uploaded a file -and, in that case, which file it was- (to insert the proper reference inside the form), we would need some kind of "feedback" coming back from the ASP.NET page to the form. [It would be like a synchronous call, waiting for the task to be done ... and then informing about the results of it].

I have been reading/thinking for a while ... and wasn't able to come with a feasible solution (I mean, any other than reimplementing the whole form from scratch without using InfoPath technology).

Thank you very much in advance!!
