Hi,
I have a funtion named unzipper() which does the work of unzipping the
files.
Is there a way I can identify what is the type of the file which'll be
passed to unzipper().
If yes, I'll be able to make out if it's a zip file or a tar or a bz2
file.
Thanks,
Ritesh 8 2123

Under Linux you can use the file command in a pipe.
In all cases, you use the "magic" repository of the file command directly like
this (I found the '\xff\xd8' for jpeg in /usr/share/file/magic.mime on my
debian)
In [69]: f = file ('samurai_tux.j pg')
In [70]: s = f.read(2)
In [71]: s == '\xff\xd8'
Out[71]: True
Thanks, Ritesh

But isn't there any library function ?
Something like
XX.filetype(nam e)
Directory
File-Tar
File-Zip
File-MPEG

Also,

throws an error.

I bet you have rebound "file" to a string, like this:
file = "some name"

This happens if you rebind names of builtins. In this case to a string.
Don't do that!
In [5]:file
Out[5]:<type 'file'>
In [6]:file = 'foo.txt'
In [7]:file
Out[7]:'foo.txt'
In [8]:file('x')

stange, did you define a function named file ?
You can use open instead.

You know all the times people say in this group "Don't use list
or str or file[HINT] or anything else that shadows a built in as
a variable name"? Now you know why.

Do I have to use some APIs? or do you know a method to find out the file

realized its great that I now know the latest file, but I need to know
the name of the file. Unfortunately, I am only passing the date into
the array.
Do I need to create a m-d array ? If so how do I create a 2-d array
where I do not know how many rows I will be looping thru ?

Afternoon,
I've spent all morning trawling the net looking for an answer to this. In the end, I've had to resort to good old fashioned asking.
How do you determine a file's MIME type using VB.NET?
The problem is:
- I have an ASP.NET web application
- I can display a list of all files in a directory on the server (it's a "directory share" for a scanner)
- I want the user to be able to select one of the files to import into the...
