or if want data dir use:

mysql -uuser -p -e 'show variables variable_name = "datadir"'

this work on windows well.

btw, when executing which mysql in linux told, you'll not installation directory on linux. you'll binary path, /usr/bin on linux, see mysql installation using multiple folders store files.

if need value of datadir output, , that, without column headers etc, don't have gnu environment (awk|grep|sed ...) use following command line:

mysql -s -n -uuser -p information_schema -e 'select variable_value global_variables variable_name = "datadir"'

the command select value mysql's internal information_schema database , disables tabular output , column headers.

output on linux:

/var/lib/mysql

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)...
