Question

I am trying to recreate the following C# code in VB6:

private void ChangeTab(string tabName, bool clearAll = true)
{
    Yadyyada(tabName);

    if (clearAll)
    {
        DoMoreStuff();
    }
}

Here is what I have so far:

Private Sub ChangeTab(ByVal tabName As String, Optional ByVal clearAll As Boolean)

    Yadyyada(tabName)

    If clearAll = True Then
        DoMoreStuff
    End If

End Sub

So far so good apart from the default parameter. Can I assign clearAll a default value of true in the method signature in the same way I can in C# or do I just need to do this at the start of the method?

Thanks

Wow this takes me back.. can I ask why you’re converting backwards technology-wise?

Anyway, you can use the Optional keyword:

Private Sub ChangeTab(ByVal tabName As String, Optional ByVal clearAll As Boolean = True)

Your issue is using ByVal. From memory, everything in VB6 was ByVal unless explicitly stated.

EDIT: I’m wrong. Default was ByRef.. it’s been so long!
