Smart Defaults

[Peter Barker]

Can anyone say what is wrong with this please:


Private Sub Combo18_AfterUp date()
Dim SQLStmt, R As Recordset
SQLStmt = "SELECT DISTINCT [Height Pixels] FROM [Pictures]WHERE
[Pictures].[Height Pixels] IS NOT NULL AND [Width Pixels]= '" & Me![Combo18]
& "';"
Me![Height Pixels].RowSource = SQLStmt
Me![Height Pixels].Requery
Set R = CurrentDb.OpenR ecordset(SQLStm t)
If R.RecordCount > 0 Then
R.MoveLast
If R.RecordCount = 1 Then
Me![Height Pixels] = R![Height Pixels]
End If
End If
End Sub

Control Source for Combo18 is Width Pixels. The idea is a “smart” default
for Height Pixels field, but I just get “Run-time error 438”

Thanks

Peter

Re: Smart Defaults

Maybe I misunderstand, but wouldn't both HeightPixels and WidthPixels be
numeric? You are enclosing the value for WidthPixels in quotes as though it
were a string.

It also appears that you are never setting the value of HeightPixels if more
than one record was returned. Try indenting your code as a reminder to
yourself.

Since you set its RowSource, I assume that the HeightPixels to which you
refer is a Combo or List Box. Could it be that it has the same name as the
Field to which it is bound? A Field, of course, does not have a RowSource.

All of the above are just observations... not related to the error you
experienced. In regards to which, so people don't have to go look up the
description of an error*, it's good to include it. It is also useful to
indicate on which line of the procedure the error occurred. Remote debugging
is difficult at best, but without all the information, it is impossible.

* most, like me, just won't take the time to do so
unless they find the problem very intriguing
