.net - ASP.NET membership using created UserId in query string -

-

hi learning .net , building first real website using .net.

i wondering if people considered ok use generated membership userid in query string? , use foreign key in database link relevant information user?

why need in querystring? provided by...

if httpcontext.current.user.identity.isauthenticated     dim user membershipuser = membership.getuser()     dim guid guid= directcast(user.provideruserkey, guid) end if

i wouldn't display such sensitive data users if wouldn't cause security issues, because application looks unsafe if can see more needs see. store temporarily in session pass page 1 page2.

if want save userid foreignkey possible use uniqueid provided membershipprovider.

if want use integer instead(readability, less disk space), have create table(aspnet_userid) maps guid int-id in one-to-one relationship. create trigger inserts , deletes on aspnet_users-table, example:

create trigger [dbo].[trgcreateuserid] on [dbo].[aspnet_users] insert  insert dbo.aspnet_userid(fiuser)     select userid inserted

and

create trigger [dbo].[trdeleteuserid] on [dbo].[aspnet_users] delete  delete dbo.aspnet_userid      fiuser in(select userid deleted)

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
