Forums Developers .len returns 0 ?

hi,

i have an edit on a dialog, it contains the text "asdf", if i type:

//echo -a $did(login_dlg, 4) it returns "asdf"

if i type:

//echo -a $did(login_dlg, 4).len it returns 0

shouldnt it be 4 ?!

try //echo -a length: $did(login_dlg, 4).len it returns 0

if the first character is a digit it will echo in that colour
so /echo -a 2 will be blue and so on.

No it shouldn't. .len doesn't work with edit you'd need to use $len($did(login_dlg, 4)).

.len works with the list control.

$did($dname,$did,<line number>).len.

The .len prop requires the 'line number' field.

• //echo -a $did(login_dlg,4,1).len

Ohh, it does work with edit then.

From the help file

len returns length of line or length of Nth line

I thought it meant *only* list entry.

My bad.

Which is kinda odd, since $did(name,id).len works for other controls, like text and buttons, and returns the same as $did(name,id,1).len. I would expect it to work without a line number in single-line editboxes (or even in multi-line ones, where N would default to 1).

Indeed, it is odd the way it works for edit controls.
Even more, with a single line edit control line numbers 1-2147483647 work :tongue:
