Hi All,
Please help me in the following problem.
I am having some files with AVI extension. I want to make two programs in
Visual Basic .NET which will work with these AVI Files. One program should
work as encrypter and another program should work as decrypter.
The frist program, encrypter should lock (the user should not be able to
open) any AVI file by editing the file. The second program, decrypter should
unlock (the user can be able to open) the encrypted file.
The editing (encryption) of the file can be done by any process or any
method. The only thing i need here is the user should not be able to use or
unlock that AVI file with out the second program (Decrypter).
Please help me, whether this Encrypter and Decrypter are possible in
Visual Basic .NET or not. Is there any other option to encrypt or decrypt
AVI Files?
With Regards,
Vanga Sasidhar

There is Crypto classes available in the framework that would make this
simple. All you have to do is read the file in as a stream of bytes then
write it back out encrypted. Do the reverse to decrypt.

I was wondering if there is a way to globally include files throughout all scripts within PHP. This is possible in ASP within the Global.ASA file but through my research I've found that PHP does not have an equivalent to the Global.ASA.

The reason for wanting to do this is because I...

Hi,
I need to open an existing file, seek to a position at X number of
bytes, and write out Y number of bytes overwriting any existing bytes,
but no erasing any other data. Is this possible?
I've opened a file in append "a" mode, and then used fseek with
SEEK_SET to seek to 0 bytes into the file, but this sets the position
at the end of existing data, not actually at the start of the file.
