HTML/CSS IE Not displaying my dropdown menu z-index related -

-

for reason cannot display dropdown menu on ie when add z-index in header of number. when remove it, works. dropdown appears behind container , content in firefox , chrome. either take out or leave in, cant seem satisfy browsers. tried making separate ie stylesheet without z-index doesnt work either. know separate ie css working because changed backgrounds uses dropdown menu in master stylesheet.

thank

edit: lets got work on ie since ie gives problems. dropdown menu appears behind content on other browsers firefox , chrome. did remove z-index in #head div. anyway fix dropdown menu without adding z-index head div?

edit: got dropdown work on ie9 firefox , chrome. not ie 6, blew up.

#head {     position:relative;     height: 140px;     width: 100%;     background: #fff;     filter:alpha(opacity=93);     padding-top:20px;     /* css3 standard */     opacity:0.93;     -moz-box-shadow: 0 0 5px black;     -webkit-box-shadow: 0 0 5px black;     box-shadow: 0 0 5px black;     z-index:1; }

ok had , there's news , bad ;)

the opacity filter in #head div means overflow: hidden being triggered, why no menus (it's unfortunate side effect of filters , overflow i'm afraid).. remove , can have z-index need anyway

next transparency (opacity) dropdowns can use rgba(255,255,255,0.9) on #nav ul li ul rule instead of #fff; (though leave #fff before rule fallback browsers can't rgba() yet.. read more!)

that's happy - can rgba() transparency ie using gradient filter..

so rule landed looked (in ie conditional comment):

#nav ul li ul {   zoom: 1;   background: transparent;   -ms-filter: "progid:dximagetransform.microsoft.gradient(startcolorstr=#e5ffffff,endcolorstr=#e5ffffff)"; /* ie8 */       filter: progid:dximagetransform.microsoft.gradient(startcolorstr=#e5ffffff,endcolorstr=#e5ffffff);   /* ie6 & 7 */     /*  behavior: url(pie.htc);*/ /* yuk filter */   }

and thought go..

but bad news

the behavior commented out because can have 1 or other, transparency or rounded corners, :( apparently

i didn't research though ymmv

i noticed problem or 3 in ie7, not sure if want support in case do.. or want check final code got stage pasted in pastebin

that code replaces main css - #head rule , whole /*navigation*/ section

update: more news , little bad!

you can have transparency , rounded corners css3 pie's own -pie-background property, but not box shadow well, way pie deals box shadow means fills div instead of drawing on outside -pie-background reading of rgba background transparent shows grey color used shadow!

my solution:

i added border make loss of box-shadow, it's not looking bad, , it's working across ie's ;) here's update conditional comment above:

<!--[if lte ie 9]> <style type="text/css" media="screen"> #nav ul li ul  {     box-shadow: none;      -pie-background: rgba(255,255,255,0.9);     border: 3px double #eee;     border-width: 0 3px 3px 3px;      behavior: url(pie.htc); /* yuk filter */ } </style> <![endif]-->

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...
