Hi,

I want to write a regular expression which may enforce input in upper case and one embedded space.
Eg. I want to give me input as "M23 9RQ".

Please help me the regular expression for this input or some other better solution like customer validator etc.

Thanks

The regex isn't complex, "([A-Z]|\d){3} ([A-Z]|\d){3}" but why do it that way at all?
Either:
1) Use a masked edit box set to upper case / digits / space as required
or
2) Upper case the input before you use it. That way the user isn't inconvenienced by having to ensure his caps key is on, or he hits the shift, etc. Makes it easier for the disabled, too.
