java - Android App Stops and Crashes when using a long nested loop -


i trying make nested loop show me on screen combinations of letters , numbers, created nested loop make string of 15 characters put in string named "pass". "tr" activity made translate numbers resulted in letters or numbers (something ascii table), thought translate activity problem commented whole thing out leaving loops , app freeze. here code:

  private void nestedlooptest() {             (int aa = a; aa < 35; aa++) {                 (int bb = b; bb < 35; bb++) {                     (int cc = c; cc < 35; cc++) {                         (int dd = d; dd < 35; dd++) {                             (int ee = e; ee < 35; ee++) {                                 (int ff = f; ff < 35; ff++) {                                     (int gg = g; gg < 35; gg++) {                                         (int hh = h; hh < 35; hh++) {                                             (int ii = i; ii < 35; ii++) {                                                 (int jj = j; jj < 35; jj++) {                                                     (int kk = k; kk < 35; kk++) {                                                         (int ll = l; ll < 35; ll++) {                                                             (int mm = m; mm < 35; mm++) {                                                                 (int nn = n; nn < 35; nn++) {                                                                     (int oo = o; oo < 35; oo++) {                                                                         pass = tr                                                                                 .translate(aa)                                                                                 + tr.translate(bb)                                                                                 + tr.translate(cc)                                                                                 + tr.translate(dd)                                                                                 + tr.translate(ee)                                                                                 + tr.translate(ff)                                                                                 + tr.translate(gg)                                                                                 + tr.translate(hh)                                                                                 + tr.translate(ii)                                                                                 + tr.translate(jj)                                                                                 + tr.translate(kk)                                                                                 + tr.translate(ll)                                                                                 + tr.translate(mm)                                                                                 + tr.translate(nn)                                                                                 + tr.translate(oo);                                                                         passtxt.settext(pass);                                                                     }                                                                 }                                                             }                                                         }                                                     }                                                 }                                             }                                         }                                     }                                 }                             }                         }                     }                 }             }         }

how can solve ? edit: app freezes 10mins , after display last generated string, how can make code show every string , pause ?

you realize have o(35^m) m = # of loops have. not desktop computer can handle many operations. don't understand you're trying do, should come better algorithm.

php - regexp cyrillic filename not matches -

i take list of files php glob(."*.pdf") . files have cyrillic names. example: ООО «Рога и копыта» then load company names database , try find them in file names: preg_match("/$firm_name/ui", $file_name, $match); i have problem: firms if $firm_name visually similar $file_name , preg_match says there no match. mb_detect_encoding both variables return utf-8. there problem in file name, or maybe there encoding or something, can not understand, ask help. upd: $file_name='ООО «Рога и копыта»'; preg_match("/... .Рога и копыта./ui", $file_name, $match); as result, ОО «Рога и копыта» , 1 О missing

c# - OpenXML hanging while writing elements -

i have program pulls data database, caches file , exports data multiple formats (excel, excel 2003, csv). i'm using openxml sdk 2.0 excel work. these export processes run in parallel (using parallel.foreach ), , amount of data can pretty large - e.g. csvs 800mb. during these larger exports, i've noticed writing of xml documents hang. instance, if have 8 exporting in parallel, @ point "pause". hang around same point: //this.writer openxmlwriter created worksheetpart. this.writer.writeelement(new cell() { cellvalue = new cellvalue(value), datatype = cellvalues.string }); when happens, pause debugger (vs2013 in case) , notice threads blocking around same portion of code - bit deeper in openxml sdk - stem call openxmlwriter.writeelement . i dug through source using justdecompile didn't find answers. appears there intermediary stream in use writing isolated storage , is, reason, blocking. underlying stream each of these filestream . here screenshot ...

sql - Select Query has unexpected multiple records (MS Access) -

i may tired, can't seem figure out happening. have 2 queries. query 1 has 10 fields. query 2 has 5 fields. fields 1 through 3 same in both queries. trying write select query , simple add field 5 query2 query1 result should query1 additional field (query2.field5). i join first 3 fields both queries , choose select records in query1 , in query2 match. don't know sql, use query designer. expect same number of records have query 1 instead have 3 times or more. can tell me doing wrong. tried reversing joins still seem same records. thanks in advance. here query: the fields in common divisionname , supplierid = vendorid , commodityname . select [part revenue exposed query p1].divisionname, [part revenue exposed query p1].commodityname, [part revenue exposed query p1].suppliername, [part revenue exposed query p1].partnumber, [part revenue exposed query p1].partdescription, [part revenue exposed query p1].bucode, ...
