Function to strip multiple characters from string ASP

This function is very handy for stripping special characters out especially before inserting into a database. You have the ability to alter the characters you require removed.

You can change the characters you want to remove in the array and if you add orr remove any simply change the iCounter number accordingly

Code:

<%
Function StripSpecialChar(inFileName)
	dim sOut,strorigFileName,arrSpecialChar,intCounter
	 arrSpecialChar  = Array("%20","%"," ","#","+","(",")","&","$","@","!","*","<",">","?","/","|","\",",","-")
	 strorigFileName = inFileName
	 intCounter = 0

	 Do Until intCounter = 20
	  sOut = replace(strorigFileName,arrSpecialChar(intCounter)  ,"")
	  intCounter = intCounter + 1
	  strorigFileName = sOut
	  'response.write strorigFileName
	 Loop
	 StripSpecialChar = response.write(strorigFileName)
end Function
%>

To call this function simply as follows

Code:

<%
Call StripSpecialChar("I want# to strip+ @specific- characters")
%>

Trying to strip a request.form item

Hi,

Tried using StripSpecialChar on a recordset item, and it worked first time . . . which is a rare event for me . . .

But then I tried using it for a request.form item and the wheels fell off.

What I want to do is strip special characters out of a form field named "message".

Can anyone offer some advice please?

I'm using dreamweaver if that's any help (or hindrance!)
