Creating Unique login links after registration

Hi techies,
good day.
Tell me how to generate login links for the users after they registered in my website.
I cant allow them to login after immediately they register.
I have send one link to their email.
Via that link only i hav to allow them to website.(Exavtly n the same process of heidisql)
Kindly,tell anybody i much highly appreciate.
thnks,

off topic. is moderately complex, details depend on the programming language used, and has nothing to do with heidisql whatsoever. seek elsewhere (eg forum systems).

hi thnks jfalch

can u suggest me any ideas for that
am using asp.net 3.5 framewrk n c#.net

this is not a forum on how to program web systems. find a forum for this (eg C#), ask there.

Dear falch,
good day.
Kindly apologise me.I am using asp.net

thnks,
