Is there a way to access all the controls in a page or form without refering to each of them by name?
For example a way to refer to them generically as an object that is a member of a collection, enumeration, list, array or some such group.
I want to create a re-useable data-driven function that can be placed in any form's "Before Show" (or other) event to examine or override a control's value or other properties.
Thanks,
Mark

Yes, add this Function to Classes.asp within the clsControls class.
Function GetItemByName(ItemName)
Dim Element
For Each Element In Objects
If Objects.Item(Element).Name = ItemName Then
Set GetItemByName = Objects.Item(Element)
Exit Function
End If
Next
Set GetItemByName = Nothing
End Function
Then you should be able to refer to Form's controls like:
Set FormControls = form_name.Controls
FormControls.GetItemByName("control_name").Visible = True
Replace "form_name" and "control_name" with own values.

Thanks, your solution worked perfectly.
However, after running your solution I have a related question:
I'm looping through all the controls to find all the TextBox controls. When then code below hits a 'Button' control, I ge this message:
Microsoft VBScript runtime error '800a01b6'
Object doesn't support this property or method: 'ControlTypeName'
( I received the same error for ControlType)
Sample Code:
If Controls.GetItemByName(control_names(x)).ControlType = csTextBox
then
do some stuff......
end if
Do all controls provide a property or method that will indicate what kind of control I'm currently working with while in the loop?
I need to take different actions on different controls and completely ignore others (buttons).
Thanks,
Mark

I'll have to check into this.
Although as a workaround you may be able to use the control names instead. For example name all your buttons "ButtonXYZ" and then check if the "GetItemByName.Name" starts with the word "Button". I haven't tried this though - just an idea...

The Button has no 'Name" property. An alternative might be to use the
GetItemByID and populate the Id property of the controls you are interested
in looping through. That, or a Select-Case to bypass the Button (possibly
others without Names).
Any good HTML reference will show which ones have a Name and which don't.

Possibly try:
If TypeName(control) <> "clsButton" Then _
If control.ControlType = ccsTextbox Then
' do something
