access vba - Trying to resolve an "invalid use of Null" in VBA -

-

quick snippet first:

dim guid string dim givennames, familyname, preferredname, gender, comments, carer, medicarenumber, patientnumber string dim dob variant dim deceased, resolved, consultnotes boolean dim age variant  givennames = null familyname = null preferredname = null gender = null dob = null comments = null deceased = false resolved = false carer = null age = null consultnotes = false patientnumber = null ' error

any idea why last variable 1 trip up? i've assigned null bunch of other strings without errors.

in vba/vb6, strings cannot set null; variants can set null. in addition, when declare variables inline comma-separated in question, last 1 typed string; of others typed variants. declare them on 1 line type have include type

dim string, dim b string ...

that's why makes sense declare them on single line.

(btw, should noted deceased, resolved typed variants same reason.)

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...
