Hi,
If FldGetTextHandle returns NULL, the field it empty!
However, I do not understand why you create a new handle h and then have the
OS overwrite it with the current text handle of the field.
h = FldGetTextHandle(FieldPtr);
This line OVERWRITES your handle h with the fields handle-h doesn�t point to
the Handle you created anymore after this call!

I use the following code to retrieve text from a field...

-------
h = MemHandleNew(50); // allocate chunk of memory in
heap
FieldPtr = FrmGetObjectPtr(pForm, FrmGetObjectIndex(pForm,
controlID));
h = FldGetTextHandle(FieldPtr);
p = MemHandleLock(h); // prevent the chunk from moving
(lock) and obtain pointer to location
MemHandleResize(h, StrLen(p)+1);
MemHandleUnlock(h);
return p;

my question is how to check that the field is not empty. If the field
is empty, I get a NULL handle error at the designated line.
thanks,
