I have a form which is bound to a table.  Some of the records in the table do not have data in the field named "Description"  If there is nothing in the description field I do not want those records to show in the form (continuous form by default).

I thought I could do it with in the onopen event of the form but this doesn't work:

    Me.Filter = [Description] <> "*"
    Me.FilterOn = True

Change the form's RecordSource query to include criteria so the records are never retrieved.

Select ..
From ..
Where Description & "" <> "";

I could have said:
Where Not (Description Is Null) AND Not (Description = "")
but the first expression handles both nulls and ZLS and is easier to understand.  Compound negatives can get confusing.

This should do it:

     Me.Filter = "[Description] Is Not Null"
     Me.FilterOn = True

Gus,
That assumes the Description is null.  It may be a ZLS which is indistinguishable visually.  In most cases, I do not allow ZLS in my tables.  They cause nothing but confusion and extra work.  It is only imports from other applications that may include them and only in staging tables.

A common way to get a ZLS in a text field that isn't set to prevent them is via a form.  If the user enters a value in a text field and then changes his mind and uses the backspace to get rid of the typing, a ZLS is saved in the field rather than null.  Access knows the field was dirtied but is now empty so it saves a ZLS.  Of course, you would get an error on save if the table does not allow ZLS.

Neither do I, and you have to actively select it. In most cases, if it is allowed, it's by an error.
That's why my filter string should do it; the wording is carefully selected.
