Hi Dude,

You can try this,

Dim RegexObj as Regex = New Regex("^\[0-9a-zA-Z ]*$")
Dim val
val = "Freinkes  9y"
RegexObj.IsMatch(val)

This will return true if your string has only alphabets,digits,spaces.

Should really be:

^[0-9a-zA-Z\s]+$

1. Whitespace is not always represent as space bar characters.
2. If you need to enforce input, you should use '+' instead of '*'.
