Hi Nadya,
How about using a combo. It could be based on a simple array like:
Public Array yesnoarray(2,2)
yesnoarray(1,1)="Yes"
yesnoarray(2,1)="No"
yesnoarray(1,2)="1"
yesnoarray(2,2)="0"
I'm using the above array to pass through a boolean to a postgres table, so you colud try to change the 1 to .T. and the 0 to .F. The array could be placed in either the load or init event of your form. Other combo properties are:
BoundColumn 2
BoundTo .T.
ControlSource Your_table_field
Number of Elements 4
Row source yesnoarray
RowSourceType 5 - array
Do not forget to release yesnoarray when when the form is closed.
