Iterate Over Static Array of Objects

Question

I want to iterate over several ComboBox objects in the same Worksheet sht:

Dim obj As ComboBox
Dim sht as Worksheet
...
For Each obj In Array(sht.ComboBox1, sht.ComboBox2)
Next obj

Runtime error 424: object required (raised at For Each ...)

I also tried to address the objects by iterating over the names:

Dim s as Variant
Dim obj As ComboBox
Dim sht as Worksheet
...
For Each s In Array("ComboBox1", "ComboBox2")
    obj = CallByName(sht, s, VbGet)
Next s

Runtime error 91: Object variable or With block variable not set. (raised at obj = ...)

1. What is the correct way?

2. And why don't these approaches work as I would expect them to?

Answer 1

Approach 1

Prepending Set as suggested by @KostasK. to the assignment works:

Dim s as Variant
Dim obj As ComboBox
Dim sht as Worksheet
...
For Each s In Array("ComboBox1", "ComboBox2")
    Set obj = CallByName(sht, s, VbGet)
Next s

Approach 2

The ComboBox is part of Worksheet.OLEObjects. In this case obj must be declared as type OLEObject to work (as long as Option Explicit is set)

Dim s as Variant
Dim obj As OLEObject
Dim sht as Worksheet
...
For Each s In Array("ComboBox1", "ComboBox2")
    Set obj = sht.OLEObjects(s)
Next s
