submit value in winform using Enter Button

Hi,

am using vb.net  2003, having 1 question on submitting information

i have 1 text box accepting UPC number " 000000000000 " 

1 - i need to validate this input as soon as user press enter ( validation in this case mean no alphabets or any other special character and length must be lets say 12 in this case.)


2 -need to submit this information after validation o lets say SP in sql 2000

i am not sure how i can do all that on enter event .


Regards
SMB
