we've been using tfs years, i'm not sure how mapping got state. when @ manage workspaces tool particular team project, there mapping: active $/data_production_system c:_portal but when @ sub-directories within project in source control explorer, of them mapped different directory structure. structure used exist - not anymore. causes problems when trying compare versions, etc. i tried removing root mapping , adding back, made no difference. on whim, tried deleting .suo file main solution team project didn't change either (nor should - paths in question don't coincide the paths used projects in solution). does know references these bad paths held? i'd delete them. i'm considering browsing through tfs , making note of bad mappings, trying override creating specific mappings folders. seems lame.

why when using matrix parameter of function must specify number of columns don't have indicate number of rows? i assume you're talking function definition like void foo( int matrix[][cols] ) { ... } this requires little background... except when operand of sizeof or unary & operators, or string literal being used initialize array in declaration, expression of type "n-element array of t " converted ("decay") expression of type "pointer t ", , value of expression address of first element of array. so, given declaration int arr[10]; the expression arr have type "10-element array of int "; unless expression operand of sizeof or unary & operators, converted ("decay") expression of type "pointer int ". if pass array function, like blurga( arr ); what blurga receives pointer int , not array of int . can define blurga as void blurga( int *ap ) { // ap[i] } the formal param...

i not find in documentation, far found out experimental calling getallframes() returns internal frames exactly in z order. does know if observation true or can give reference it? does know if observation true i yes. or can give reference it? look @ source code getallframes() method. iterates through components in container. , since components in zorder when iteration returned array in zorder.

i have machine multiple websites. websites not use same domain name. example 1 website test.test1.com test.test2.com. have uc certificate lists of domains doesn't use wildcard * in of domains. when try create bindings each can't add host header binding https. if use appcmd second domain can no longer access first domain. how setup bindings can access test.test1.com default port 443 , test.test2.com when host header? thanks help!! gary in iis 7 can not have ssl bindings based on host headers. if want multiple sites https , don't have wildcard certificate, have use multiple ip addresses, 1 each ssl site. add ip addresses os , set dns entries them, bind sites against ip addresses, not host names.

from rpm .spec file documentation, version tag intended correspond version of software being packaged. release tag intended increment new build of .rpm . what point of release tag then?? if software has not changed in meantime , version same, definition software , behaves same, , .rpm file before, release should same. suppose original .rpm file lost need recreate it, , there no changes, then, of course recreated file should before - 1 wants in case of no changes software. i don't need release tag, please explain me. added: docs @ http://www.rpm.org/max-rpm/s1-rpm-inside-tags.html say (...)if necessary repackage software @ same version, release should incremented.(...) maybe not mean? maybe intended here is, "repackage software @ same version, there may minor changes not deserve new version, increment release instead". meant here?? there lot of factors go binary rpm file, beyond upstream version of source code. compiler/configure opti...

i have project several sub-directories. works fine, except if try access files inside /root/javascript directory, 404. files in fact exist, , in fact typing path correctly. if rename directory can access files. rename back, , 404 again. vhost file works fine. no .htaccess files involved. apache version: 2.4.9 os: ubuntu 13.10 after searching , trying different things, here's problem came down to: by default, apache 2.4 on ubuntu enables config file called javascript-common, redirects requests files inside /javascript (that is, directory @ root of project called 'javascript') /usr/share/javascript. solution 1 use following command disable javascript-common configuration file: a2disconfig javascript-common solution 2 add javascript files inside /usr/share/javascript directory. way apache find files , no 404 returned. 1 benefit of doing things way won't need multiple copies of same files (jquery.js, etc.js) multiple projects use... solution 3...

can add mixin variable in less? something this @input-border-radius: .rounded(); or @h1: .font-size(46) // pulls rem calculator mixin. looked @ less docs can't see way it. there way. you can define properties of (possibly immaginary) class , recall properties of class in style of different class. example: .fontstyling { font-weight: bold; color: black; } h1 { font-size: 46px; .fontstyling; } h2 { font-size: 38px; .fontstyling; } (thats not best way format headings - other exemples useful!)
