c++ - Is there a way to specify user data for Shell_NotifyIcon using NIF_INFO? -


i able mark each balloon user data (an id or void*) when receive nin_balloonuserclick can identify balloon clicked , perform action meaningful specific notification. far can tell, isn't possible given notifyicondata structure.

as far can tell, isn't possible given notifyicondata structure

that correct. there no provision in shell_notifyicon() api associating user-defined data notifications.

however, since can display 1 balloon @ time anyway, store data somewhere off side, , retrieve when balloon dismissed. if have multiple notifications, use stack of kind store data, , have balloons pop data stack.

another option use different ucallbackmessage value each individual balloon when using nif_message flag, , have window message handler differentiate between message ids needed. instance, if have array of data, pick unique base message id (maybe registerwindowmessage() , add array index it.

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
