InputBox backwards compatibility problem

Question

There seems to be a problem with the InputBox that Microsoft gives us for backwards compatibility.   In VB6, if the user clicked cancel, it used to give back a string with a 0 pointer.   Now it gives back String.Empty.  Unfortunately this is ambiguous with the user clearing the text and clicking OK.

In VB6 you used to be able to do this;

Dim input as String
input = InputBox("Enter some text, or else")
If StrPtr(input) = 0 Then
  Msgbox("You clicked cancel.")
End If

Is there any way in .Net to duplicate this behavior?  Our program logic depends on being able to differentiate between a Cancel and an OK with blank text.  I would prefer not to have to write my own input dialog, but may have to if there is no other solution.

Hi Collin,

I think that you can use the customized Dialof(using form) to implement this requirement. I didn't find any parameters to supply your required information in this situation.
