Problem while getting files' thumbnail

Question

Hi,

I've made an app which loads files into listviews, and those files have a large thumbnail which is achieved by this code:

http://www.datafilehost.com/get.php?file=3510e755
(so long code so uploaded a text file...)

It works like a charm except... Except when an "*.mp3" file doesn't have a album cover so it has no thumbnail... Then app crashes on the line which contains "throw ex" and says "NotImplementedException"...

I got no way to solve it so I'll be really thankful for help...

Maybe a code which retrieves whether the file has a thumbnail or just a simple icon...

Thanks in advance...

How is this posting any different than http://www.codeproject.com/Questions/810857/Problem-with-getting-file-tumbnails?arn=7?
http://www.datafilehost.com/get.php?file=3510e755 is a URL for something it is not the code that you wrote and is causing a problem.

I think it's mistakenly double posted, really sorry for that...

And no, that's not written by me, I'm not that expert but I can fix that if I know how can I understand whether an icon has thumbnail or no...

Oh God it must've been much much much easier :/

NotImplementedException is typically used by a programmer to indicate that a feature or workflow has been stubbed in, but not actually implemented, or occasionally to indicate a condition or state that is unexpected/shouldn't happen.

In your case is sounds like the application does not expect to encounter a file without a thumbnail, and so the exception is thrown.

The only solutions are:
1. Don't feed it files like that.
2. Get the source code and have it skip these files.

You're right but this program must show all kind of files with or without thumbnails, and, I can't get the code skip those files, I'm confused...

Perhaps you need to write it, not "get"... :-)

We're programmers. If you post code, we can help.

Of course. OP should understand: getting help is not the same as getting the whole work done for him.
We will gladly help by an advice on how to write some code, fix a bug and a lot more.
