Question:

I'm trying to have backup logs automatically sent via e-mail. What's happenning is that it's sending the first line of the file, and that's it. With a hex editor, I found that immediately following the line it does send is:

00 0D 0A 00 0D 0A

(space, CRLF, space, CRLF - I think)

By taking the spaces out, the whole file goes. Does winbatch think it's the EOF when it sees that pattern?

Answer:

That's

00 0D 0A 00 0D 0A

(*NULL*, CRLF, *NULL*, CRLF - I think)

(Space is a 20 )

The *NULL* signifies end of data. Its considered binary information making it a non-text file and beyond the capability of the SMTP function.

Presumably you could "massage" the file prior to email to remove the null characters. How big is the file. For not-too-big files you could add this code....

*NOTE: TOTALLY UNDEBUGGED*

fn="C:\temp\yourbackup.log"
fs=FileSize(fn)
bb=BinaryAlloc(fs)
BinaryRead(bb,fn)
fsX=fs-1
for xx=0 to fsX
    byte=BinaryPeek(bb,xx)
    if byte==0 then BinaryPoke(bb,xx,32)
next
BinaryWrite(bb,fn)
BinaryFree(bb)

;Now do the SMTP stuff 

Note 32 decimal == hex 20 == ascii space
