ASP String limit

[Jay]

I have an HTML form with a textarea. When passing large
amount of data in the textarea, the Processing asp pages
catch an error message as follows:
Error Type:
(0x80020009)
Exception occurred.

The error is generated once the trim or length or replace
function is called on the field when long text is passed
in the textarea.
Is there a max limit on the string length that these
functions can process?
What else can be done to done to fix this problem?

Thank you,

If it is an ASP serverside code problem, post the code.

If not, ask a clientside NG.

The problem is when I call the following function that I
have created:

Function Clean(InString)

Clean=Replace(TRIM(InString), "'", "''", 1, -1, 1)

End Function

The function works well if the data passed is "small".
However when I pass larger values I get the exception. I
think larger is more than 5000 char. I have not yet
tested for the max number of char that I can pass.

I'm using Windows XP with IIS ver 5.1
Your help is highly appreciated.

Thank you,

An interesting question.

Since we are now on a ASP Newsgroup(NG) I surmize you are using
serverside ASP VBscript.

So the content of the Instring has to be brought from somware. If itis
passed from a form/get the maximum is 4000 chars, I think, if it is a
form/post the maximum could be 5000, I wouldn't know.

Perhaps that is the error bug.

You could always use a brute force equivalent of your function for
testing if the error is in your function:

Function Clean(InString)
InString = trim(InString)
clean = ""
for i=1 to len(InString)
clean = clean + mid(InString,i,1)
if mid(InString,i,1)="'" then clean = clean + "'"
next
End Function

slow, but reliable [I hope, not tested]

Although I don't think you are getting to that high of a number

I have used a similar function to your "Clean" with content up to 102,399
characters, without difficulty.

The solution is quite simple.
Don't use Replace

Imagine I have a HTML form,
I would just fetch the data and store it in SQL using a parameter

Set cmd = CreateObject("ADOB.Command")
