did try fix way labview interferes normal alt-tab behaviour using autohotkey? alt-tab inside labview puts non-labview windows end of list. so if have alt-tabbed labview window browser takes (2 × number_of_currently_open_labview_projects -1) keystrokes back. great idea. find functionality annoying , there doesn't appear easy fix anywhere on web. here's script. 2 quick notes: i had lot of trouble re-mapping alt-tab. if that's critical can try starting here help. to knowledge it's not possible rid of "screen flicker" because windows requires delay between keystrokes. note: adapt code various windows - "ahk_class" using window spy tool included in autohotkey installer . code #noenv ; recommended performance , compatibility future autohotkey releases. #warn ; enable warnings assist detecting common errors. sendmode input ; recommended new scripts due superior speed , reliability. setworkingdir %a_scriptdir% ; ensur

so have pretty huge solution many projects, few of them use dlls other projects in solution, projects copy files other directories after build performed.

(the error not give me data on went wrong) so before sit debug of this. know how can smartly manage build actions performed locally , via build server , see deltas? i able build solution same on build server on machine (with directory structure, post build events..etc) thanks lot the accepted way you're after use nuget managing assembly references. can publish dependent assemblies nuget part of continuous delivery process, reference (and update!) dependencies in solutions consume them necessary. this removes ambiguity ("what version of foo.dll project x using?") , reduces runtime errors ("why

i've run problem when attempting express pointer type within macro. take simple example. #define index_of_data(data, type, index) \ ((type *)data)[index] this works: index_of_data(buffer, float, 3); where fails: index_of_data(buffer, float[2], 3); because cast should (float(*)[2]) . is there way express "the pointer of type " , ...without using typeof ? (which isn't standard c). note, there of course other ways make specific example work. cast char , offset sizeof(type) * index example. interested in way express pointer type in c. doing heavily complicated stuff c types may fun sport, it's extremely confusing in real code. to avoid wrecking heads on complicated pointer expressions much, people use typedef ! if typedef types expect use macro of yours, won't have problems. observe: #include <stdlib.h> #define index_of_data(data, type, index) \ ((type *)data)[index] int main(void) { float (*buffer)[2]

this question has answer here: extract digits string in java 12 answers i have several lines of text such as: "you current have 194764bleh notifications" "you current have 32545444bleh notifications" "you current have 8132bleh notifications" "you current have 93bleh notifications" what's best way integers text ? currently using line.split twice, once "have" , once "bleh". seems inefficient doing integers. are there better ways that? e.g. string str = "you current have 194764bleh notifications"; str = str.replaceall("\\d", ""); // replace non-digits using regex take away non-digits option, not restrict having 'have' & 'bleh' wrap numbers. not entirely sure efficiency compared using split though.
