i have excel file have cell multiple values, split comma. instance: new york, chicago, los angeles. want rearrange cell in alphatical order, like: chicago, los angeles, new york. there easy way this? try this. following code read values in column a , give desired result in column b . sub sortstring() dim myarray variant, varswap variant dim long, min long, max long, lastrow long dim str string dim myrange range dim isswapped boolean lastrow = cells(rows.count, "a").end(xlup).row set myrange = range("a1:a" & lastrow) each cell in myrange myarray = split(cell.value, ",") min = lbound(myarray) max = ubound(myarray) - 1 isswapped = false = min max if myarray(i) > myarray(i + 1) varswap = myarray(i) myarray(i) = myarray(i + 1) myarray(i + 1) = varswap iss...

the code working has multiple headers , source files different classes face.cc, face.hh, cell.cc, cell.hh edge.cc edge.hh , headers contain includes this, #ifndef cellincluded #define cellincluded #ifndef faceincluded #define faceincluded i saw through http://www.cplusplus.com/forum/articles/10627/ , saw way write include guard #ifndef __myclass_h_included__ #define __myclass_h_included__ so in above code working on, compiler automatically understands looking face.hh or cell.hh files? better question : writing __cell_h_included__ same cellincluded ? #ifndef __myclass_h_included__ #define __myclass_h_included__ so in above code working on, compiler automatically understands looking face.hh or cell.hh files? no, compiler doesn't automatically understand mean. what happens that, when compiling translation unit , compiler holds list of globally defined macros. , so, doing defining macro __myclass_h_included__ if doesn't exists. if mac...

i want make small application read title current opened youtube video firefox or chrome browser , save in .txt file on computer. i need idea on how accomplish this. somehow possible access tabs opened in firefox or chrome via c#? do understand me? want somehow parse data browser seleceted tab , save .txt file. would have use greasemonkey scripts this? if tab active this string browser = "firefox"; //or change chrome/iexplore var browserproc = process.getprocessesbyname(browser) .where(b => b.mainwindowtitle.contains("youtube")) .firstordefault(); if (browserproc != null) { string maintitle = browserproc.mainwindowtitle; } you can parse relevant parts of maintitle if need to.

i trying series of vectors come same original, make easy example, suppose vector v= (1,2,3,4,5,6,7,8,9,10) (of course mine bigger) the first vector has this: r1=(1,3,5,7,9)= v(1:1:end) second vector: r2=(2,4,6,8,10)=v(2:1:end) third vector: r3=(3,5,7,9)=v(3:1:end) fourth vector: r4=(4,6,8,10)=v(4:1:end) ... r8=(8,10)=v(8:1:end) so questions are: is there easier way result? how can know total number of ri vectors distance = 1 can obtained v ? use matlab's cell object can hold vector in every cell. use loop fill cell object gradually. code example: %initialize v v= [1,2,3,4,5,6,7,8,9,10]; %initialize empty cell of size [10,1] r= cell(length(v)-2,1); %fill cell ii=1:length(r) r{ii} = v(ii:2:end); end %prints results ii=1:length(r) r{ii} end results (each row different vector): 1 3 5 7 9 2 4 6 8 10 3 5 7 9 4 6 8 10 5 7 9 6 8 10 7 9 8 10

i'm making app on existing database in firebird charset windows-1250. , im getting lot of troubles because of encoding, cant change it. my biggest error when im making form input object called notification this: form |f| panel iconv.conv('windows-1250', 'utf-8', 'opis zgłoszenia:'), :class=> 'panel_dodaj_new' f.input :opis_zgloszenia, label:false end end try save text in utf-8, want save in windows-1250. how force :opis_zgloszenia save in different charset utf-8? i find way change encoding in controller. in create method add: @notification.opis_zgloszenia = iconv.conv('windows-1250', 'utf-8', @notification.opis_zgloszenia) also need change update method: if @notification.update(notification_params) @notification.opis_zgloszenia = iconv.conv('windows-1250', 'utf-8', @notification.opis_zgloszenia) if @notification.save redirect_to request.url end end...
