Question

I come from an Object Oriented background. Why does “Test” (notice the quotes) display (in the message box) in this code fragment. I would expect the logical test: ‘If Test = “True”‘ to return False because the variant contains a Boolean and not a String. Therefore I would not expect the Message Box to appear, but it does:

Dim Test As Variant

Test = True

If Test = "True" Then //line 5
    MsgBox ("Test")
End If

Answer 1

Variant type values in VB6 (and most other languages that support them) automatically convert between data types as needed; they’re used extensively in COM interactions.

The code you’re using uses the automatic (implicit) conversion from boolean to string here:

if Test = "True"

after using it as it’s original assigned type (boolean) here

Test = True

Here, though, you’re not using the variant at all; you’re using a hard-coded string "Test".
