How to display a date before three months using date time picker from access database

[anzarriyaz]

Hi experts,
I'm a student currently doing a final year project named blood banking system.

I'm using vb.net and ms access as the back-end.

I have a doubt in date time picker control.

I added a field named dlast in my access database.

If search for a new donor in the database the result will be the three months date before the dlast field.

for eg: the dlast field is 01-March-09 then result will get like 01-January-09.

Please help me.Very Urgent.


Thanks in Advance.
