azure - Best Table Structure Design for Synchronization or Replication -


dears,

i have choose following table structure common tables in application : 

create table [dbo].[equipm]( [id2] [uniqueidentifier] not null, [id] [bigint] identity(1,1) not null, ...... ......   constraint [pk22_equipm] primary key nonclustered ( [id2] asc)with (pad_index = off, statistics_norecompute = off, ignore_dup_key = off, allow_row_locks = on, allow_page_locks = on) on [primary]) on [primary] textimage_on [primary]

explanation:
guid primary key not clustered. use newsequentialid()
bigint unique , clustered index, , used relations other tables.

question 1: structure optimal ?
question 2: shall use guid primary key , relations other tables since use synchronization or may replications in future ? if yes, consequences should keep in mind ?

extra information
above design used in application support multi user signing different geographical locations, use sql azure sync databases between main office of company , branches.

i hope post clear
thanks

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
