I have a search form with 21 check boxes on, I have to perform a search depending on which check box has been checked. There can be any number of boxes checked.

My problem is, how do I work out which box or boxes have been checked and pass the results to the SearchResults form?

Hi peter,

Have a peak at:

You might find it useful. Its how I routinely do multiple-parameter searches. The search form builds the appropriate WhereCondition string in code, stores it in the variable strWhereCondition, then opens a search results form filtered by the WhereCondition.

DoCmd.OpenForm FormName:="frmSearchResults", WhereCondition:=strWhereCondition

To add checkbox criteria to the WhereCondition building code, add a parameter like:

  '-----------------------------------------------------------------
  ' 5. Build BatteriesIncluded parameter
  '-----------------------------------------------------------------

    If Me!chkBatteriesIncluded Then
        If IsNothing(strWhereCondition) Then
            strWhereCondition = "([BatteriesIncluded] Is Not Null)"
        Else
            strWhereCondition = strWhereCondition & " AND ([BatteriesIncluded] Is Not Null)"
        End If
    End If

HTH,

Or you might need:

If Me!chkBatteriesIncluded Then
        If IsNothing(strWhereCondition) Then
            strWhereCondition = "(Not [BatteriesIncluded])"
        Else
            strWhereCondition = strWhereCondition & " AND (Not [BatteriesIncluded])"
        End If
End If

or

If Me!chkBatteriesIncluded Then
        If IsNothing(strWhereCondition) Then
            strWhereCondition = "[BatteriesIncluded]"
        Else
            strWhereCondition = strWhereCondition & " AND [BatteriesIncluded]"
        End If
End If

If BatteriesIncluded is a boolean (Yes/No) field, the first snippet above would fulfill a request for a checkbox labeled:

"Don't list products that include batteries"

In my previous post, BatteriesIncluded would be a text field in your data source that stores the type of batteries included. So:

 If Me!chkBatteriesIncluded Then
        If IsNothing(strWhereCondition) Then
            strWhereCondition = "([BatteriesIncluded] Is Not Null)"
        Else
            strWhereCondition = strWhereCondition & " AND ([BatteriesIncluded] Is Not Null)"
        End If
    End If

would fulfill a request for a checkbox labeled:

"List all products that include batteries" (i.e., the BatteriesIncluded field isn't null).

It all depends on what type of data your check boxes indicate should be included in the query.

HTH,

Bob

Ok Bob
thanks for the quick reply, I'll give it a try..
