sql - Updating Inserted record using triggerc -


i have table need update column's value identity of inserted record.

following trigger have written: 

create trigger [dbo].[updaterecordid] on [dbo].[employee] after insert  begin        update dbo.employee     set recordid = (select employeeid inserted ) employeeid= (select employeeid inserted ) end

the trigger created when insert record table following error:

maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32).

if don't put condition in update statement , write trigger following:

alter trigger [dbo].[updaterecordid] on [dbo].[employee] after insert  begin        update dbo.employee     set recordid = (select employeeid inserted ) end

i following error:

subquery returned more 1 value. not permitted when subquery follows =, !=, <, <= , >, >= or when subquery used expression. statement has been terminated.

what best practice update record keep primary key in column can add more records in same table , keep them related?

i can write update statement in stored procedure inserting record using @@identity wanted same using trigger.

you should join table on inserted table can contain more rows.

create trigger [dbo].[updaterecordid] on [dbo].[employee] after insert  begin        update e     set recordid = i.employeeid      dbo.employee e     inner join inserted on i.employeeid = e.employeeid end

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
