Narayana,
This method that I am using masks the one you mention. Here is the
method definition:
static void * GetObjectPtr (UInt16 objectID)
{
FormPtr frm;
frm = FrmGetActiveForm ();
return (FrmGetObjectPtr (frm, FrmGetObjectIndex (frm, objectID)));
}
Regards,
JV

hi,
i am also a newly learning palm devoloper. I do not know whether your
'GetObjectPtr' in fldP = GetObjectPtr(ApgarInput);
is your own method. if not u should use FrmGetObjectPtr(pointer to form,
objectindex). the prototype and definition is:
Prototype void *FrmGetObjectPtr (
const FormType *formP,
uint16_t objIndex
)
Parameters → formP Pointer to the form. → objIndex
Index of an element in the form. You can obtain this by using
FrmGetObjectIndex().
and continue with FldInsert().
you are getting error because your program does not know which form (memory)
should it access. try this and and kindly let me know if you are able to
get the answer.
But to efficiently insert text use FldGetTextHandle() method.
