Brad,
That's very kind of you, thanks!
James.

James (and the list),
The JS code isn't anything special and is pasted below. Comments
show usage. The 'countfield' parameter allows you to dynamically
update an on-screen message area to indicate remaining allowed
characters.
function textareaSizeLimit (field, countfield, maxlimit) {
// // Used to limit how much text can be typed or pasted into a
form textarea.
// Installed 2005-Apr-13, bdp w/ modifications.
//
// Usage: <textarea name=message // ...
// onKeyDown="textareaSizeLimit
(this.form.message,this.form.remLen,125);" //
onKeyUp="textareaSizeLimit(this.form.message,this.form.remLen,125);">
// </textarea>
//

// Dynamic 'fix' by: Nannette Thacker

if (field.value.length > maxlimit) {
field.value = field.value.substring(0, maxlimit); // if too
long...trim it!
alert ('This field only allows ' + maxlimit +
'characters'); // ... and let user know
}
else countfield.value = maxlimit - field.value.length; //
otherwise, update 'characters left' counter
}

James,
I haven't implemented that solution, but got the idea from a
project where we've had to warn users about pasting in to much
text (the target 4D field is type text).
I have the JavaScript code that does the textarea character count.
I'll dig it up and send it to you privately.

Brad,
Yes, what a neat idea!
I agree with Aparajita, however the customer doesn't, as it's
their dime I'll try and implement Brad's idea!
Cheers all
James.

You could use Javascript to check the size of your text field
and chunk any text > 32K into hidden 'overflow' variables. Then
on form submit, concatenate textfield + textover32K +
textover64k+... into the blob.
Brilliant!
But if people are regularly sending large >32K, I would argue
from a user interface standpoint an upload is preferable.
Pasting >32K of text is kind of unwieldy, and they must have
gotten it from a file in the first place.
