I like that it creates stand alone exe's and has a long list of user defined functions.

I also wrote a component that's more efficient. I haven't looked at that code for awhile. I think it will write bytes to a file without needing to load the file. But it uses basic VB methods like Seek, Put, etc. I'm not certain that the file is not loaded "behind the scenes" with those methods. http://www.jsware.net/jsware/scripts.php5#jsbin

I'm sure there is a *simple* way, but unfortunately, your first post did not mention if you will always be replacing the characters with the same number of other characters, if the characters to be replaced are in a fixed location within file, or even what OS this will be used on. -- Todd Vargo (Post questions to group only.

Sorry for my lack of precision, I didn't think that was important. The replacement is always located in the firt line of the text file. The firt line is always of this form : ------------------------------------ number: 2345 ------------------------------------ where : - "number: " is a label which never changes. - "2345" is a number which changes. In fact, the number increases. So, the number of characters can change, it's possible to have "12044". But this number represents the number of printed pages by a user. So, it's almost sure that the necessary number of characters will be lower than 20 (for example). The script should work sometimes in Windows 2000 server and sometimes in Windows XP pro. I hope this time, my precisions are enough. :-) -- Fran�ois Lafont |
