change a report property if * used in query parameter

[Stan]

In this where claus if the user types * for the parameter [Time Period] the
report that uses it displayes the first record field value in the
corresponding text box. I want to substitute that value for something like
all. how can I do this?

 

[Stan]

The where statement is
WHERE (((Survey1.DaySegment) Like UCase([Time Period])) AND ((Survey1.[Date
Surveyed]) Between [DateStart] And [DateEnd]))

The most flexible solution is to omit the parameters from the query, and
instead build a WhereCondition from only the boxes on a form where the user
enters something.

The article contains a sample database you can download and see how it
works. The sample filters a form, but the technique of building the filter
string is identical for filtering a report.
