Hi, Any more thoughts on this? This is what I do currently:
$oldBLOB_x:=Old($CurrentField_ptr->) Case of : (BLOB size($oldBLOB_x)=0) & (BLOB size($CurrentField_ptr->)=0) : (Generate digest($oldBLOB_x;MD5 digest)=Generate digest($CurrentField_ptr->;MD5 digest)) Else // It's different End case Is there a more efficient mechanism?
