google chrome - How can i create a new tab via browserAction and then execute a script -

-

i want create tab clicking on browser action button , insert content script or execute script. far, not working well.

background.html

chrome.browseraction.onclicked.addlistener(function(tab)  {    chrome.tabs.create({url: "dreamer.html"}, function(tab)    //dreamer.html file in extension    {         //add script        chrome.tabs.executescript(tab.id, {file:'dreamer.js'});    }); });

manifest.json

{    "name" : " dreamer",    "version" : "0.1",    "description" : "my extensionr",    "browser_action" : {"default_icon" : "app/appdata/images/icon.png", "default_title":"start   dreamer" },    "background_page" : "app/appdata/background.html",    "content_scripts" :[{"matches":["http://*/*"],"js":["app/view/uimanager.js"]}],    "permissions": [ "cookies", "tabs", "http://*/*", "https://*/*" ] }

i error in background page

error during tabs.executescript: cannot access contents of url "chrome-extension://femiindgnlfpdpajimkmldpgpccngfmd/dreamer.html". extension manifest must request permission access host.

i know how create tab(new tab) , run script immediately

edit:

the kind of application creating requires following actions:

-allow user create new tab clicking browseraction button
-on creation of new tab, file in extension (dreamer.html) opened
-add content script or execute script in new tab

thanks

is there particular reason need inject script? since both dreamer.html , dreamer.js seem hardcoded, include <script type="text/javascript" src="dreamer.js"></script> in former, right?

as side benefit, if need send info background page, can access directly chrome.extension.getbackgroundpage() instead of setting complex listeners come content scripts, too.

injecting content scripts injecting scripts outside extension sandbox. dreamer.html, however, part of extension.

edit

if want (unwieldy) example of how execute script in extension page, see here:

http://code.google.com/p/chromium/issues/detail?id=30756#c11

i don't think applies case, however.

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...
