File upload - Network path was not found
This is mind boggling to me. I've been at this for 2 weeks. I've put debug steps and I thought I'd fixed it but still get the same error.
This is what I'm doing:
1. I build a letter in code
2. I have it as PDF
3. I want to save it in database
4. I also fax the letter using a 3rd party API. This works
Sometimes, it doesnt happen all the time...i get the error below. I've run out of ideas on what I need to do to get rid of this error...
at System.Data.SqlTypes.SqlFi
I think it comes from the database when I'm trying to save the doc
My code:

Can you paste the UserControl_NonMemberFax.b

Here it is. I put debug steps all over that submit code to see if I can capture the error and I think maybe it's coming from the store proc. Any insight would be great

could it be because of this port 445?

I know the error is coming from that function because the code never reaches the line of debug after it: dc.usp_debugfileUpload("La
I can add the try catch you have as well. Now, if you look at my stored proc...is there a way to keep retrying that stored proc or anyway to keep retrying the save function. It doesnt happen all the time...it happens sometimes so I can keep retrying in the code...if possible

Yes, you can keep retrying it, but you have to code the correct if/else or try/catches and depending on the result, i.e. if (success) { next step } else { function(); }
ASKER
i wonder why it's happening to begin with. Is it firewall, is it connection, why it happens sometimes and why it doesnt at times...it's weird.

>>To avoid this and other headaches it is good practice to not store the file in a directory somewhere then instead of storing the actual file in SQL, just store a link / directory path to where the file is stored.
Isnt using SQL Server 2008's filestream recommanded by Microsoft? With Filestream, the actual file is not stored in SQL...correct?
