Any way to handle an exception thrown from called c# exe in c++? -


i wonder way handle inner exceptions of called exe c++ code?

my sample code:

char *fprog = "..\\consoleapp\\ezf\\encryptzipftp.exe"; char *fpath = "c:\\users\\min\\desktop\\foto"; char *fpass = "wxrfsdmkh1994wxrmk";  char command[500]; sprintf (command, "%s %s %s", fprog, fpath, fpass);   try  {    system(command); } catch(exception &err) { }

you need check return value system() (as need check return value c functions). this:

int status = system(command); if (status == -1)     std::cerr << "oops, not launch " << command << std::endl;  int rc = wexitstatus(status); if (rc != 0)     std::cerr << "error " << command << ": " << rc << std::endl;

if child program @ well-behaved, return nonzero indicate failure when unhandled exception occurs.

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)...
