I am validating numbers typed into a text box but it is not allowing spaces.

What I have tried:

If Asc(e.KeyChar) <> 8 Then
If Asc(e.KeyChar) < 46 Or Asc(e.KeyChar) > 57 Or (Asc(e.KeyChar) < 48 And Asc(e.KeyChar) > 46) Then
e.Handled = True
MessageBox.Show("Invalid character")
End If

Exactly the same why you do for letters in your previous question: How to allow backspace and space when validating letters in VB?[^]
Just replace IsLetter with IsDigit
