[ACFUG Discuss] Urgent help needed.. CF custom tag to read tab delimited text file. HOw to add trim functionality??

[Ajas Mohammed]

Hello everyone,
I need help on this one real quick. One of my colleauges used this custom CF
tag which parses a tab delimited text file and stores in array. How do I add
functionality to this code so that it would trim all the spaces i.e either
left or right or if value sent in txt file has spaces?

If you understand the code , that will be great and if you could pinpoint me
to what needs to be done, then nothing like it... Also any explanation of
this code will help a lot.

I tried ltrim(rtrim(colvalue)) while inserting records but it doesnt work in
sql server 2000. Once records are inserted in table, I am not able to trim
the records.. If you know any sql server 2000 fix for removing extra spaces
left or right or remove extra spaces for values which are sent with empty
tabs or spaces???

Thanks in advance.. Had to resend this,because the attachment was not
accepted, here is the code...







   
   

   
   
   
   

   
   int_NextPos = REFind("#arguments.str_Delimiter#|$",
arguments.str_Content, int_CurrPos);
   while (int_NextPos gt 0)
   {
   str_Token = trim(mid(arguments.str_Content, int_CurrPos,
int_NextPos - int_CurrPos));
   arrayAppend(ar_Tokens, str_Token);
   int_CurrPos = int_NextPos + len(arguments.str_Delimiter );
   int_NextPos = REFind("#arguments.str_Delimiter#|$",
arguments.str_Content, int_CurrPos);
   }

   // If the line ends with a token, add
   // an extra empty element to the array
   if (len(arguments.str_Content) gt 0and mid(arguments.str_Content,
len(arguments.str_Content), 1) is arguments.str_Delimiter)
   {
   arrayAppend(ar_Tokens, "");
   }

Seth,
What Dean says is pretty valid and is often talked of.  There has been more
success with putting distorted math equations into captcha images.

This is typically a first line of defense though.  It is recommended that
you monitor the data submitted through the forms and then filter the data
submission for scripting attacks and a black list of keywords.  The black
list approach can be very tedious and becomes adaptive over time.

Wordpress uses Akismet for spam protection and it works pretty well. (

 image generator/validator spam prevention
  

I know this has
 come up previously, but I don’t know
 what to search for.
I need to generate
 an image that has that skewed text on it,
 so that spammers can’t read it, to
 validate the form submission is a human.
1) What do you
 CALL that thing?
2) Do you know
 if there is a tag or function out there somewhere
 (hopefully free) that auto generates it?
Thanks

Its called CAPTCHA.  And its easily bypassed by computers or humans.   
If there is enough value behind the CAPTCHA some cheap south Asia  
labor will break them day and night.
