I use FWH 19.06 , Harbour , ADO
Ther is differnce betwenn 19.06 and FWH 18.07 ( which I use as an official version )
The problem is the class datarow.prg and the memo fields
If the memo field is NULL
- with FWH 18.07 ? valtype( oRec:MEMO) ---> C
- with FWH 19.06 ? valtype( oRec:MEMO) ---> U
this causes me several errors
