Hello im new to this forum

I posted this request twice into some forums and sadly no luck

I had a richtextbox1 contains the following text:

Code:
<REPLY username =chicco1502
status = OK
user_id =3377436
>
<user_register.php: 2011-02-19 10:00:06

and so on..

So once i click button1 it should extract only Email plus Password into

Email:Password

edwardzh*[email protected]:640716
gabriele.sc*[email protected]:010585

so the email sympol is email= <email that should be extracted here>
and so the password sympol password= <password that should be extracted here>

if you didn't exactly understood what i meant you could download the source code about little clear example about what i needed here
