 |
|
Hi folks,
I have been trying to parse a mail header to remove the subject line and
just give the" from name"
however i can't find out what the the seperator is
example of header------
meathome<meatwork@mail.com>just a test
here it shows as a " " on a simple text editor (notepad its a vertical bar)
when I copy the seperator in a @asc() it tells me its a period ( .) or 46
and thats not quite right...
thanks for the input...

Hi Harry,
The character you posted is the ASCII character "7". As in @chr(7)... Strange that an email header would have such a character?
| Code: |
%%Myheader = "meathome<meatwork@mail.com>""just a test"
%%Myheaderlen = @len(%%Myheader)
%%cnt = 1
repeat
%%Char = @SubStr(%%Myheader,%%cnt)
Info %%Char@CR()@asc(%%Char)@CR()
%%cnt = @Succ(%%cnt)
until @Greater(%%cnt,%%Myheaderlen)
|
I hope the above code helps you.

Hi all,
Something is wrong with the VDS code option on the forum... When you download the script above it does not include the script just the header...
Below is a resubmit with the regular PHPBB Code button...
| Code: |
%%Myheader = "meathome<meatwork@mail.com>""just a test"
%%Myheaderlen = @len(%%Myheader)
%%cnt = 1
repeat
%%Char = @SubStr(%%Myheader,%%cnt)
Info %%Char@CR()@asc(%%Char)@CR()
%%cnt = @Succ(%%cnt)
until @Greater(%%cnt,%%Myheaderlen)

as i said the seperator is different (each time) if its copied and pasted
on this site or into notepad or even the vds script window....
i agree with you that its strange!!!!!!!!!!!!!!!!!

Harry,
Open the header of the email with a Hex editor to see what the value of the character really is. I take it is in a file if your downloading the email with a custom application right? If so there is a Hex editor demo that comes with VDS 5 that you can use to view the header. If you using VDS to capture the header then just iterate through the characters of the header with the code that I posted and it will actually show you the character that is being sent.
I am thinking that it is something specific to either the POP3 or SMTP servers that are in the chain when the email is sent and recieved from point A to B...
If all else fails you can try reading the RFC (ie.. Request for comments)for email. The RFC you want to read is rfc822 and can be found here ftp://ftp.isi.edu/in-notes/rfc822.txt
or
here http://www.worldtalk.com/Standards%20and%20Tech/emailref.shtm
