I have managed to get bools to work with Access and VB.
My set up is:
On the windows side:variables are declared as booleanBools as char is OFFMaxlongvarchar=4094 (Not part of the bool
problembut fixed another
problem)Row versioning ON
On the PG side:variables declared as bool int4eq functions and operators for xid/int and bool/int as described
in the ODBC doco.
HTH,
