VB.NET Inputbox - How to identify when the Cancel Button is pressed?

Question

I have a simple windows application that pops up an input box for users to enter in a date to do searches.

How do I identify if the user clicked on the Cancel butt

Answer 1

I know this is a very old topic, but the correct answer is still not here.

The accepted answer works with a space, but the user can remove this space - so this answer is not reliable. The answer of Georg works, but is needlessly complex.

To test if the user pressed cancel, just use the following code:

Dim Answer As String = InputBox("Question")
If String.ReferenceEquals(Answer, String.Empty) Then
    'User pressed cancel
Else if Answer = "" Then
    'User pressed ok with an empty string in the box
Else
    'User gave an answer
