file io - Perl in memory content writing in raw mode -


i using perl 5.10.0 , trying write content in memory buffer in raw mode. not working. in following code snippet tried compare result between 3 scenarios

my ($s1, $s2); open rawf, '>:raw', \$s1;     #<-------  opening in memory reference in raw mode print rawf 'hello world in raw mode', "\n";  open fh, '>:raw', 'testfile.bin'; #<-------  opening file in raw mode print fh 'hello world in file', "\n";  open norf, '>', \$s2;   #<-------  opening in memory reference in normal mode print norf 'hello world in normal mode', "\n";     print $s1;    #<------ doesnt print print $s2;    #<------ prints expected

however, if use perl 5.14.* works. limitation of perl 5.10.1? or should done in other way work?

apparently bug fixed in perl 5.12 timeframe. see perlbug #80764 - though initial report/fix doesn't mention problem, problem comes in discussion on bug , rolled patches.

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)...
