Thanks, that is a good solution.
But I did something else.
I thought a little about it and i think that true and false
sayes more than 1 and 0.
Therefore I desided to keep that. Insted I did the following.
When I'm about to save the data I use
sp_columns to get the
Type_Name from the table.
If the Type_Name is bit I convert the true/false to
1/0
