Trying to use IIF as ternary operator/without evaluating both sides

Question

I need to use iif() for my case of checking and assigning values like:

Range(\"A1\").Value = IIf(IsNull(Range(\"A2\").Value), MsgBox(\"1\"), MsgBox(         


        

Answer 1

The VBA documentation for IIf states that it executes both True and False conditions regardless of its output.

You need code similar to the following:

Dim Result as Integer
If IsNull(Range("A2").Value) Then
    Result = MsgBox("1")
Else
    Result = MsgBox("2")
End If
Range("A1").Value = Result

Alternatively, if you're looking for an one-liner:

Range("A1").Value = MsgBox(IIf(IsNull(Range("A2").Value), "1", "2"))

Though this doesn't allow you to change the other MsgBox parameters as easily as the block-If.
