Even though that's the correct MIME type for an .xlsx file, I suggest you ask the maker of the web service for what it recognizes and supports. It's entirely possible that it doesn't support an .xlsx file, but maybe an older Excel format.
At this point, anyone to answer is just guessing, as are you.
Ravi has provided you with a link that should answer your question, so I'm not going to add to it. I'd like to make a suggestion as well. If you can, change the format of the date:
yyyy-MM-dd yyyy_MM_dd or yyyymmdd or somesuch
The format you have can be ambiguous between US and European date formats. This might not be a problem in itself (you may only ever deal in US dates). The other thing changing the date will do is allow you to sort the files by date via their filenames.
hi guys , today i have read sth about exponential memory i dont know what is it or even if its exist or not .
can you guys give me some info , i need sth like this , bcz im working on a puzzle 8 problem and i want to slove it with bfs algorithm , and every time i start my code it gave me a overflow error bcz it fill up the memory too fast and make the program stop of working so , is that things that im noticed (exponential memory ) is really work or not ? and can you suggest me sth ?
From what I gather, I think you need to rethink your strategy. .Net can hold up objects in memory up to two GB I believe, if that's not enough for a puzzle 8 problem you're really, really going into the wrong direction.
