OK; I changed to numeric(8,4) for this field; what happens is:
VB does'nt regocnize decimals anymore:
from pgsql:
update auftrag set rabproz = 5.5;
from VB in debug mode:
? data1.recordset!rabproz
5.5
? data.recordset!rabproz > 5
True
? data.recordset!rabproz < 6
False
? data.recordset!rabproz > 50
True
? data.recordset!rabproz < 60
True
and bound controls display the value without decimals ?
What am I doing wrong ?
