i have following code snippet getting wrong output. class program { static void main(string[] args) { var = 10000; var j = 10000; console.writeline((object) == (object) j); } } i expecting true getting false you boxing numbers (via object cast) creates new instance each variable. == operator objects based on object identity (also known reference equality) , seeing false (since instances not same) to correctly compare these objects use object.equals(i, j) or i.equals(j) . work because actual runtime instance of object int32 equals() method has correct equality semantics integers.

i know when add submodule git repository tracks particular commit of submodule referenced sha1. i'm trying find sha1 value stored. the .gitmodules , .git/config files show paths submodule, not sha1 of commit. the git-submodule(1) reference speaks of gitlink entry , gitmodules(5) reference doesn't either. it stored in git's object database directly. tree object directory submodule lives have entry submodule's commit (this so-called "gitlink"). try doing git ls-tree master <path-to-directory-containing-submodule> (or git ls-tree master if submodule lives in top-level directory).

thanks bunch tip on static of folks answered! feeling little less frustrated now. i not going ask questions step step through whole assignment, want make sure way go 1 of next tasks. have written following, compiles fine (the purpose check string make sure numeric, , user may have entered isbn number or without dashes): private string validateisbn(string booknum) { string[] book; int j=0; ( int i=0;i<booknum.length();i++) if (character.isdigit(booknum.charat[i])) booknum.charat[i]=book[j];j++; i haven't written next part, has allow x last digit in string (which apparently how isbn numbers work). assume if above correct (or close), need check ninth character digit or x, writing like: if book[9] isdigit() || if book[9] == "x" || if book[9] == "x"; is right (isbn numbers 10 numbers or 9 numbers , x @ end)? the last digit of isbn-10 check digit. since method supposed check if entered isbn c...

i able add multiple label controls panel , display them on onlick event. code have want first time, label simple replaced new label on second onlick event , on. here have far: private void createtasklabel(guid goalid, string goal) { label tasklabel = new label(); tasklabel.id = goalid.tostring(); tasklabel.text = goal.tostring(); taskpanel.controls.add(tasklabel); } so, instance, creates new label uniqueid (handled elsewhere) , places within panel , displays it. when onlick fires again, same label replaced instead of new 1 appearing below it. dynamically created controls not persisted after postback. need keep track of how many controls have generated , regenerate of them each time work how want. basic implementation: list<string> labeidlist = new list<string>(); override saveviewstate(..) { if (labelidlist.count>0) { viewstate["labeldilist"]=labelidlist; } base.saveviewstate(..) } override loadvie...

i keep running problems unresolved imports in django project (in eclipse w/ pydev). after googling while on given issue can find right thing add pythonpath solve problem. seems i'm missing concept or process can definitively "obviously there should add thing import properly". makes more frustrating i'm following basic django tutorial, i'd expect these things dealt with. in java world pretty clear because can find out library particular package coming from, download , add build path. equivalent concept in python/django world? i not looking solve specific problem here, rather know steps follow, or up, or concept missing. or possibly find out there not 1 , guesswork... i running on ubuntu 10.10, python 2.6 from question assume quite new python, let's start @ beginning. my advice @ traceback django generates , search line looks this: "importerror: no module named somemodule". tells name of missing module. once know name of modu...

i have algorithmic problem in have derived transfer matrix between lot of states. next step exponentiate it, large, need reductions on it. contains lot of symmetry. below examples on how many nodes can eliminated simple observations. my question whether there algorithm efficiently eliminate symmetry in digraphs, way i've done manually below. in cases initial vector has same value nodes. in first example see b , c , d , e receive values a , 1 of each other. hence contain identical value, , can merge them. in example spot, graph identical point of view of a , b , c , d . respective sidenodes, doesn't matter inner node attached. hence can reduce graph down 2 states. update: people reasonable enough not quite sure meant "state transfer matrix". idea here is, can split combinatorial problem number of state types each n in recurrence. matrix tell how n-1 n . usually interested value of 1 of states, need calculate others well, can next leve...

i'm trying unusual powershell parsing. basically, have literal string contains name of variable. tell powershell "hey, i've got string (may) contain 1 or more variable names--dynamically parse it, replacing variable names values" here's textbook way understand parsing works: ps c:\> $foo = "rock on" ps c:\> $bar = "$foo" ps c:\> $bar rock on and if change value $foo: ps c:\> $foo = "rock off" ps c:\> $bar rock on no surprises here. value of $bar parsed assigned, , didn't change because value of $foo changed. ok, if assign $bar single quote? ps c:\> $foo = "rock on" ps c:\> $bar = '$foo' ps c:\> $bar $foo that's great, there way powershell parse on demand? example: ps c:\> $foo = "rock on" ps c:\> $bar = '$foo' ps c:\> $bar $foo ps c:\> some-parsefunction $bar rock on ps c:\> $foo = "rock off" ps c:\> some-parsefunc...

i in process of creating website small company, catalog page shows categories , listing of products. have images each product, stored in 1 folder per product, each folder containing small, medium , large version of file (for use in diff. places). is recommended/more efficient combine small, medium , large images in 1 folder each, when catalog listing dynamically created using php / mysql server (shared hosting) doesn't have in 10 different folders, there 1 image each? would notice 10 items per page/request? (total of 500 products?) how images created , prepared? mean image software stores 1 size per folder. if kept there's no intermediate step necessary move/copy images. guess efficiency not different. may ask if use framework site?

i have image in imageview placed in scrollview., zoom in , out performed on pinches, now, want zoom in , out on clicking buttons placed zoom in , zoom out. how it? there option? if knows please tell me. thanks in advance. you can set zoom scale of scroll view programatically based on tap of button. simple implementation: - (ibaction)zoomin:(id)sender { if(scrollview.zoomscale < scrollview.maximumzoomscale) { scrollview.zoomscale = (scrollview.zoomscale + 0.1); } } - (ibaction)zoomout:(id)sender { if(scrollview.zoomscale > scrollview.minimumzoomscale) { scrollview.zoomscale = (scrollview.zoomscale - 0.1); } }

i made own implementation of strlen in assembly, doesn't return correct value. returns string length + 4. consequently. don't see why.. , hope of do... assembly source: section .text [global stringlen:] ; c function stringlen: push ebp mov ebp, esp ; setup stack frame mov ecx, [ebp+8] xor eax, eax ; loop counter startloop: xor edx, edx mov edx, [ecx+eax] inc eax cmp edx, 0x0 ; null byte jne startloop end: pop ebp ret and main routine: #include <stdio.h> extern int stringlen(char *); int main(void) { printf("%d", stringlen("h")); return 0; } thanks you not accessing bytes (characters), doublewords. code not looking single terminating zero, looking 4 consecutive zeroes. note won't return correct value +4, depends on memory after string contains. to fix, should use byte accesses, example changing edx dl .
