I have to restrict the user to enter string with any space or any backslashes. Rest all characters shoul be allowed. I tried earlier with below string for regex. 

Please correct or help me with a new regular expression to help me with the same. I am doing this in access - vba

`[^0-9a-zA-Z~@#$%^&*()_?<>,.[]{}|-+=]`.   
I am novice in using regex.

Problem solved by this.

```
[\s \\ \/]
