Power,

In whatever method you are opening the view put code like this;

* Whatever method
LOCAL ldStart, ldEnd
ldStart = Thisform.TxtStartDate.Value
ldEnd = Thisform.txtEndDate.Value
* Then either
USE TheView
* OR
Requery("TheView")

In the view desinger set up your filter as;

DateField >= ?ldStart AND
DateField <= ?ldEnd

The ? will make those variable names view parameters and VFP will use the variables to resolve the filter when you opne or requery the view.
