i dont use DmNewHandle but I do use DmStrCopy in the function that is
inserting the records into the db...
is there anything wrong with that?
------
void insertRecFormDb(VoidHand FormHand,FormContainer* FormStruct, PODSMgr*
mgr)
{
CharPtr s;
UInt offset =0;
if(MemHandleResize(FormHand,20) == 0)
{
s = MemHandleLock(FormHand);
offset = 0;
DmStrCopy(s, offset, FormStruct->FieldValue);
MemHandleUnlock(FormHand);
}
}
