Cancel with Input Box

Cancel with Input Box

Cancel with Input Box

(OP)
Does anyone know how to handle Cancel with an Input Box, and distinguish it between an empty string when hitting Enter?  I've seen code that looks like:

Sub TestInput()
Dim ans As String
ans = InputBox("Response:")
If StrPtr(ans) = 0 Then
  MsgBox "You hit cancel"
  Exit Sub
ElseIf ans = "" Then
 MsgBox "You hit OK with no entry"
 Exit Sub
Else
  MsgBox "Your answer is " & ans
End If

but when I tried this, and strptr(ans) seems to be a random number?  Any ideas what's missing?  Using Excel 2002 btw.

RE: Cancel with Input Box

The code you posted worked fine for me.  Needed to add an End Sub at the end, otherwise didn't have to do a thing.

I've got Excel 2000.

RE: Cancel with Input Box

I have Excel 2003 and it worked fine. Like Mint said, had to add the end sub line.

RE: Cancel with Input Box

(OP)
The end sub is in my code (simply forgot to copy it to here), but it still doesn't explain why there is a random number generated by the strptr() function.

RE: Cancel with Input Box

I have never seen nor used the StrPtr() function, but it looks and smells to me like it is a pointer. Thus it may be returning an address that points to the data. Depending on what memory is available at the time, then it may return what appears to be a 'random' address. If cancel is selected, the pointer never gets assigned, and thus the call returns zero.

Just a hunch...
