RE: null characters in a file
Kelly, We ran into this EXACT same problem about a month ago. We were doing a cffile, then parsing through the file to modify it and then spitting the modified version to screen. We discovered, as you did, that cf chokes on null characters and were perplexed at what to do. In our situation, we ended up modifying the file on the back-end, through perl, when the file was placed in the directory (business rules state that the file gets ftp'd from the main frame to a directory on the web server). It made perfect sense to do any modifications on the back-end - why slow down cf when you know that every time you get a file, you have to modify it. After the file was modified on the back-end, we were free to call the file anyway we wanted. I.E. cffile, cfcontent, cflocation, etc. Hope that helps.

RE: null characters in a file
That's what we are considering now using VB we aren't running perl on our machine here and I would rather not hopefully VB can handle it. We are just going ot have VB split the file in 2, CF will edit the one portion then VB would put them batch together. Is Cold Fusion able to CALL a vb script/executable? I am assuming it can just have never done that. Do you know the best way to CALL something like that? Make it a COM Object?

RE: null characters in a file
I've never called a vbscript before. I would assume that if you made it an exe, that you could call it through cfexecute or, as you mentioned, instantiate an object and call it that way. Another reason we decided to modify files on the back-end instead of on-the-fly was because some of our files were rather large (up to 2mb). The size of the file, coupled with parsing, was wy to slow.

RE: null characters in a file
Not 100% sure but in CF5 isn't there a binary read, which you could then convert to a string or am I assuming binary64 on this, anyone? -Original Message- From: Kelly Matthews [mailto:[EMAIL PROTECTED]] Sent: Tuesday, 1 January 2002 3:28 PM To: CF-Talk Subject: null characters in a file Using CFFILE to read a file.

RE: null characters in a file
I heard of a similar problem. I met this guy at devcon who was using cf to
dynamicaly build images on the fly but when he got to a null on a string of
bits cf would balk. The solution escapes me atm. He was from the uk and if
he's reading this im sure he'll share his genius.
Good luck,
