vba - Get Column name from a query table -


with normal tables, can access column name using 

select column_name information_schema_columns table_name = '" & tbl & "' "

and works...

but during execution of vba code need retrieve columns name not tables, table resulting after query, how can in vba?

dim qry querydef dim mrgtbls querydef dim t1 string dim t2 string dim sqljoin string

...

set mrgtbls = currentdb.createquerydef(qry.name, sqljoin)

... , later on want create query such as

select column_name information_schema_columns table_name = 'mrgt'

which returns nothing since table mrgt not in information_schema_columns, unlike other tables.

to column names querydef, can use fields collection:

dim firstcolumnname string firstcolumnname = mrgtbls.fields(0).name

alternatively can use pure sql , msysobjects , msysqueries system tables. see here details structure of table.

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)...
