r1 , r2 asking gender of person.

r1 male , r2 female

r3 , r4 asking whether user continue.

r3 yes , r4 no.

when click r1 , r3 becomes unchecked , vice versa. similar case r2 , r4. @ time can check 1 radio button. how can around problem . groupbox essential cannot remove it.

radiobuttons grouped parent-control. sufficient re-group them in panel.

current layout:

groupbox     radiobutton     radiobutton     radiobutton     radiobutton

new layout:

groupbox     panel         radiobutton         radiobutton     panel         radiobutton         radiobutton

c# - Is it possible to remove an existing registration from Autofac container builder? -

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
