vba - mid()=foo in VBS? -

-

in vba , vb6 can assign mid example mid(str,1,1)="a" in vbs doesn't work. need because string concatenation freakin' slow here actual code hacked real quick

function fastxmlencode(str)     dim strlen     strlen = len(str)     dim buf     dim varptr     dim     dim j     dim charlen     varptr = 1     buf = space(strlen * 7)     dim char     = 1 strlen         char = cstr(asc(mid(str, i, 1)))         charlen = len(char)         mid(buf, varptr, 2) = "&#"         varptr = varptr + 2         mid(buf, varptr, charlen) = char         varptr = varptr + charlen         mid(buf, varptr, 1) = ";"         varptr = varptr + 1     next     fastxmlencode = trim(buf) end function

how can work in vbs?

authoritative source explicitly stating it's not available in vbscript:

visual basic applications features not in vbscript:

strings: fixed-length strings lset, rset mid statement strconv

vba has both mid statement , mid function. vbscript has mid function.

the 1 other option have if stuck doing in vbscript make api calls. since comfortable working directly string buffer might not big jump you. page should started: string functions

sorry, looks api calls out, too: rube goldberg memorial scripting page: direct api calls unless want write activex wrapper calls, we're starting awful lot of work (and additional maintenance requirements) now.

php - What is the difference between $_SERVER['PATH_INFO'] and $_SERVER['ORIG_PATH_INFO']? -

-
what’s difference between $_server['path_info'] , $_server['orig_path_info'] ? how use them? when run print_r($_server) , path_info , orig_path_info not present in array. why not? how can enable them? i have read php manual on them, still don’t understand them. the path_info variable present if invoke php script this: http://www.example.com/phpinfo.php/hello_there it's /hello_there part after .php script. if don't invoke url that, there won't $_server["path_info"] environment variable. the porig_ prefix uncommon. path_info standard cgi-environment variable, , should never prefixed. did read that? (there issues around php3/php4 if invoked php interpreter via cgi-bin/ - hardly has such setups today.) for reference: http://www.ietf.org/rfc/rfc3875

queue - mq_receive: message too long -

i implementing communication between 2 processes using queue. problem when call function mq_receive, error: message long. i have done following: struct mq_attr attr; long size = attr.mq_msgsize; .... // initializing queue "/gateway" int rc = mq_receive(gateway, buffer, size, &prio); if print size value, size=1, while when print same size program (got same mechanism), not long integer ( -1217186280 )... how can solve error?....so while size = 1, believe it's right "message long" why 1? p.s. have tried put : int rc = mq_receive(gateway, buffer, sizeof(buffer), &prio); but no result. it seems need read docs more carefully. when call mq_receive should pass size of destination buffer. this size must greater mq_msgsize attribute of queue . in addition, seems have error in queue attributes initialisation makes proper mq_receive call impossible. here standard message queue session: fill mq_attr struct ( doc ): struct mq_a...
