hibernate - Database design consideration on foreign-key both way between two tables -


i have 2 class, user , status, while user have number of status, naturally many-to-one relation , can mapped db tables.

however, requirement need user maintain “current” status, i.e., in user table, need have foreign-key status table. result of having 2 foreign-keys between 2 tables in opposite direction.

one obvious problem of once records inserted 2 tables, can delete neither of them cause deleting 1 table violate other table's foreign-key.

what best design situation?

  1. in status table , add column determine whether status record "current" or not. ** for performance issues , can set "current" status records '1' value , rest null value
    1. you don't have use 2 foreign keys , 1 - status user.
    2. if using hibernate post's tag :) can create view in database select "current" status records , have same structure status table.
    3. connect view user entity using one-to-one relation,

i hope helped !

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
