Dear All,
I have a problem with some of the users of my web application. Couple of them started to complain that they can't open a report exported to excel and downloaded and when I try to open this XLS file with the report they are sending me I got the following message:
"Office File Validation detected a problem while trying to open this file. Opening it may be dangerous."
Then if I go and export this report by myself it's working without a problem. The file is a bit bigger in size so I assume that the user is not downloading the XLS file completly and this is the problem. My suspicion is that the user has very poor internet connection and the transfer is terminated before the file is downloaded completly.
The report that I'm referring to is a local RDLC report created in MS VS2005. I'm using report viewer 2005 control embeded on a aspx page. Some techincal details:
- .Net framework 3.5
- Microsoft SQL Server 2008 (SP3) - 10.0.5512.0 (X64) Aug 22 2012 19:25:47 Copyright (c) 1988-2008 Microsoft Corporation Standard Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1) (VM)
Now the question is how to make sure that this is the case? Also if yes then how to make sure that the user will manage to download the file completly?
I cannot see any errors in the event log. Is there any place where I can look into to see if there are any potential problems with the XLS file generation?
Thanks in advance,
Dzordz
