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>
//

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.
