Validate Using Regular Expressions

[Jster]

I'm having a difficult time in finding or making my own user validating Regular Expression. The format for our User name is something like BOB.12345. If I use the RegExp "[^a-zA-Z0-9\.]", and I put in ' or 1=1-- in the text field, it displays or 1=1--. It didn't even strip out the = or the --.

Here is the code:

Function Sanitize(strInput)
     Set regExLogin = new RegExp
     regExLogin.Pattern = "[^a-zA-Z0-9\.]"
     Sanitize = regExLogin.Replace(strInput,"")
End Function

Any help would be appreciated.

Thanks,
Jster

Function Sanitize(strInput)
     Set regExLogin = new RegExp
     regExLogin.Pattern = "[^a-zA-Z0-9\.]"
     Sanitize = regExLogin.Replace(strInput,"")
End Function

My knowledge in Regular Expressions is not so good since I've only used them on a few occasions, but I believe your pattern is incorrect format. Shouldn't it be something like this?

^[a-z]|[A-Z]\.[0-9]

Give it a try and see if it works. Meanwhile, I'll look more into this and see if I can find an answer.
