Nesting Inputbox If Statements

Question

This is probably a simple question, but if I need to collect data at the start of a sub, using several input boxes, which one of these is the right way?

Example 1:

InputText1 = InputBox("Enter your name")  
If InputText1 = "" Then Exit Sub

InputText2 = InputBox("Enter your age")
If InputText2 = "" Then Exit Sub

'Do something

Example 2:

InputText1 = InputBox("Enter your name")  
If Not InputText1 = "" Then  
  InputText2 = InputBox("Enter your age")  
  If Not InputText2 = "" Then  
    'Do something  
  End If
End If

Answer 1

I think a better way would be to create a form asking for all of the data.

However both your sets of code work. It depends on if you believe that there should only be one exit in a procedure. Your second example only has one exit. The reasoning for that is that you always know where it exits. However the downside is that the code becomes nested and more complex visually. I prefer to exit if he condition is simple and the subroutine is ending with an error exit ie not doing something. SO I would prefer Example 1.

There is another returned state you can test for: the Cancel button.

Dim InputText1 As String

InputText1 = InputBox("Enter your name")
If StrPtr(InputText1) = 0 Then
    MsgBox "*Canceled*"
ElseIf InputText1 = "" Then
    MsgBox "*Empty*"
Else
    MsgBox InputText1
End If

It may not matter in this case, but it can be useful to tell the difference.
