Question about Visual Studio *.sln file format -

-

i using text editor manually edit *.sln file. confused following lines:

project("{fae04ec0-301f-11d3-bf4b-00c04f79efbc}") = "test2008", "tools\test2008\test2008\test2008.csproj", "{00b5ebb2-fda5-4b23-bdc5-27e9f82e7c69}"     projectsection(projectdependencies) = postproject         {82b9bec0-c9cc-4423-b54f-61e3c4af53d8} = {82b9bec0-c9cc-4423-b54f-61e3c4af53d8}     endprojectsection endproject

what's point of

{82b9bec0-c9cc-4423-b54f-61e3c4af53d8} = {82b9bec0-c9cc-4423-b54f-61e3c4af53d8}

statement? looks totally superfluous.

it seems redundant syntax 1 of quirks required msbuild recognize project's dependency:

it appears visual studio keeps dependencies in 2 ways, 1 of read msbuild. see because still can specify dependencies in gui, copy solution other machine , build vs in correct order. -victor sergienko

as why "superfluous equation statement" required, seems assigning project's guid own guid workaround issue msbuild 4.0 causes msbuild not recognize or respond project dependencies listed in solution (.sln) file, or build dependencies out of order.

the screwed "{x}={x}" syntax you're asking variation of standard msbuild syntax referencing project (i.e. example @sergio's answer).

apparently, embedding dependency declaration in projectsection block in conjunction self-named dependency guid causes msbuild change build order of depended-upon project, doesn't add reference it.

there's discussion on microsoft connect wherein workaround discussed. in it, dan microsoft suggests cleaner workaround msbuild glitch in 2nd post on page, , mentions fix you're asking about:

that fixes ordering, libraryproject wait on codegeneratingproject, build otherwise not affected. can tidy removing dependency in solution file - removing these lines, unnecessary:

projectsection(projectdependencies) = postproject     {b79ce0b0-565b-4bc5-8d28-8463a05f0edc} = {b79ce0b0-565b-4bc5-8d28-8463a05f0edc} endprojectsection

and still works fine.

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

fortran - Function return type mismatch -

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...
