Multi Select For Query

[Ryan]

I have copied the following code into my Database however I cannot get it to
work if the field is of a Date type. I can change the varValue data type from
Variant to Date however this then damages all other fields. Any ideas?

Function IsSelectedVar( _
strFormName As String, _
strListBoxName As String, _
varValue As Variant) _
As Boolean
'strFormName is the name of the form
'strListBoxName is the name of the listbox
'varValue is the field to check against the listbox
Dim lbo As ListBox
Dim item As Variant
If IsNumeric(varValue) Then
varValue = Trim(Str(varValue))
End If
Set lbo = Forms(strFormName)(strListBoxName)
For Each item In lbo.ItemsSelected
If lbo.ItemData(item) = varValue Then
IsSelectedVar = True
Exit Function
End If
Next
End Function

"I cannot get it to work if the field is of a Date type."
What does this mean? What happens?
It sounds like you need to treat date data as a string, you can use CStr()
function?

Ryan -

What do you mean by 'damages all other fields'?

Have you stepped through the code to see what is happening?

I don't understand this piece of code - why would you convert a date (which
is stored as a number) to a string, and then try to compare it to a date in
the list box? I would remove this (comment it out).
If IsNumeric(varValue) Then
varValue = Trim(Str(varValue))
End If

If there could be some dates and some date/times in the comparison, I would
change the comparison to be this:
If DateValue(lbo.ItemData(item)) = DateValue(varValue) Then

You also need your function statement to set varValue As Date.

If this doesn't help, let us know what you mean by 'damages other fields'...
