C++ - multi-dimensional arrays and variable lengths? -


so, dealing code base attempting merge several code bases 1 neat stack. i'm running trouble byte arrays use. our stuff based around communication via byte arrays, , each of our apps stores messages needs send so:

byte arr[] = {0x00, 0x01, 0x02};

so now, smashing arrays arrays of arrays try group them together, so:

byte grouponearrs[][15] =  {    {0x01, 0x02, 0x03}, };  byte grouptwoarrs[][15] =  {    {0xff, 0xa9, 0xaa}, };

and etc. however, running issues, because sizes of individual messages must preserved, because in order messages considered valid, must same lengths defined them as. got around defining int array actual lengths of each element, it's dirty. there easier way store these 2d arrays, preserve lengths of each individual array?

edit: it's sounding i'm sol vs 2008 , variable-length 2d arrays in header files. there way work around with, say, struct? like

struct message{    byte message[20];    int size; }

and initialize like...

message messages[] = {    {{0x01, 0x02, 0x03}, 3}, };

well, should say, tried this, , blew up. that, anyway. don't want have make variable names each array preserve size, seems silly.

rather making 2d array, use adjacency list. vector should best purpose. come handy in forming adjacency lists.

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)...
