dll - RunTime Error 380 - Specified Fieldname not found in object -

-

i running vb6 application pervasive v9.5 database. receiving runtime error 380 - specified fieldname not found in object when 2 of users trying log in. rest of office fine...does have idea issue be? have searched few hours , can't find helpful.

the login uses vaccess control during login. caused missing dll or ocx file on client machine?

any suggestions appreciated out of ideas.

edit:

with valogon     .refreshlocations = true     .ddfpath = datapath     .tablename = "userlog"     .location = "userlog.mkd"     .open     if .status <> 0         errmsg = "error opening file " + .tablename + " - status " + str$(.status) + vbcrlf + "contact department"     end if end

i have enabled vadebug mode , on workstation in question, when app launched receive ddf error:

the vaccess control unable open field.ddf @ specified ddfpath. may result error in ddfpath or refreshlocations properties, or corrupt field.ddf.

then error message: 

acbtr732 - btrieve status = 170, brtrieve opertation code = 0, vaccessname = valogon, valocation =

then login prompts username , password , once login button clicked when user receives 380 runtime.

the error 170 means "database login required. authentication database failed due wrong or missing username." sure datapath variable has proper path in it?

can connect database through pervasive control center? require user/password?

a corrupt ddf on server typically affect users.

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

i'm attempting recode old c++ program in fortran make use of lapack (i'm aware c++ have lapack++, i'm having lot of trouble installing it, gave up). i didn't have problems compilation, when had variables declared real . when started coding section of program required lapack, found parameters passed dsyev need double precision . tried change double precision (including changing hard coded numbers double precision counterparts, i.e. 0.0 -> 0.0d0) when try compile, following error of functions , subroutines i've written: error: return type mismatch of function <function> @ (1) (real(4)/real(8)) i'm not sure coming from, in program has been changed double precision. for example, i've declared following: double precision :: alpha(3),d(3),zeta1,zeta2 double precision :: a1(3),a2(3),d1(3),d2(3) double precision :: pi pi = 3.14159265359d0 alpha = (/0.109818d0, 0.405771d0, 2.22766d0/) d = (/0.444635d0, 0.535328d0, 0.154329d0 /) 10 i=1,3 ...

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...
