Hi. I have had similiar kind of things happened to me. You best bet is the API reference at palmos.com.
The comment for the FldGetTextPtr says this: -------------------------------------- The pointer returned by this function can become invalid if the user edits the text after you obtain the pointer. Do not modify the contents of the pointer yourself. If you change the text while it is being used by a field, the field's internal structures specifying the text length, allocated size, and word wrapping information can become out of sync. To avoid this problem, follow the instructions given under FldGetTextHandle. ----------------------------- There shouldn't be any surprise. :) Max --- Dave Mottorn <[EMAIL PROTECTED]> wrote: > That worked.
