because of asking last question , i've changed code use return . have problem return: know should use return (where comment in code below) dont know how should define work? help. public double bigzarb(int u, int v) { double n; int x=0; int y; int w=0; int z; string[] = textbox7.text.split(','); int[] nums = new int[i.length]; (int counter = 0; counter < i.length; counter++) { nums[counter] = convert.toint32(i[counter]); } u = nums[0]; double firstdigits =math.floor(math.log10(u) + 1); v = nums[1]; double seconddigits = math.floor(math.log10(v) + 1); if (firstdigits >= seconddigits) { n = firstdigits; } else { n = seconddigits; } if (u == 0 || v == 0) { messagebox.show("the multiply 0"); } string threshold = textbox9.text; int intthreshold = convert.toint32(threshold); int intn = convert.toint32(n); if (intn <=

i have been struggling code quite time. loading xml google maps , geocoding addresses xml. need add delay code when there many addresses @ once. here entire code doing this i need have load xml file delay, loads @ once , geocoder can not handle many requests when xml large. xml file changing continuously needs reloaded , re-geocoded. becomes problem when xml file becomes larger, when need work most. i have placed delay around geocoder.getlocations(address,createmarker); address variable contains addresses not delay it. if place delay around var address = markers[i].getattribute("address"); not pass i variable function. can give appreciated. // create marker function createmarker(response) { var place = response.placemark[0]; var point = new glatlng(place.point.coordinates[1], place.point.coordinates[0]); var marker = new gmarker(point); gevent.addlistener(marker, "click"

so i've been using mysql_real_escape_string insert data database...but when replaces apostrophes symbol ’ so instead of display it's, it's displaying it’s....... is there way reconvert ’'s apostrophes when read database? this character encoding issue in way. because in utf-8, ’ (u+2019) encoded 0xe28099. , represents characters â (0xe2), € (0x80), , ™ (0x99) in windows-1252 . so seems forgot specify output character encoding properly browser uses default character encoding windows-1252 instead.

i hope switch between 2 uiviewcontroller using uinavigationcontroller. (auiviewcontroller, buiviewcontroller relate uiview aview,bview) aview has uibutton, bview has uibutton also. if press button on aview, push bviewcontroller , display bview. if press button on bview, bviewcontroller pop , go auiviewcontroller. i hope use uinavigationcontroller's navigation function hide 'go back' bar , navigation bar, use 2 buttons tell uinaviationcontroller needs do. possible? to hide uinavigationcontroller's navigation bar: [self.navigationcontroller setnavigationbarhidden:yes]; to push view controller button: - (void)pushnextviewcontroller { nextviewcontroller *page = [[nextviewcontroller alloc] initwithnibname:nil bundle:nil]; [self.navigationcontroller pushviewcontroller:page animated:yes]; } to pop view controller one: - (void)poptolastviewcontroller { [self.navigationcontroller popviewcontrolleranimated:yes]; }

i in process of reviewing old java/jdbc code clob-handling on oracle database. existing code uses approach similar approach mentioned in this question . i found an article states: prior oracle jdbc 10g, manipulate clob data in jdbc, oracle extension class oracle.sql.clob used. now, oracle jdbc 10g has few enhancements simplifies clob manipulation in jdbc applications. enables handling of large data using of available standard apis, instead of using oracle extension classes. the article gives following information details of enhancement: by default, method preparedstatement.setstring() allow processing of strings 32765 bytes. in order insert data greater 32765 bytes, newly introduced connection property - setbigstringtryclob can set. forces preparedstatement.setstring() use newly introduced method, oraclepreparedstatement.setstringforclob() instead. however warns: ... handling large amounts of data way may not wise; streaming data better alternative. but a

i know can't have 2 programs listening same port, wondering if possible fake somehow, example: my machine has 2 applications, 1 listening port 80 , other port 6653 . if incoming connection, let's mysite.com:80/chat forwarded internally application listening on port 6653 , data returned server forwarded port 80 somehow. the reason want accomplish because there many firewalls seem block connections ports other 80. i have chat server want run on port 80, perhaps ip , machine that, feels trouble single chat server. any helpful feedback appreciated. thanks! you can mod_rewrite if you're running apache. link has plenty of examples, including want (i think). edit: see you've updated tags "asp.net". i'm guessing you're not running apache, then. i'm sure there similar tool iis, or can use proxy server same thing.

i'm learning basics of programming here (c#) think question generic in nature. what simple practical situations lend closer particular type of loop? the while , for loops seem pretty similar , there several questions addressing differences between two. how foreach ? basic understanding, seems ought able foreach loop within for loop. 1. foreach , for a foreach loop works ienumerator , when for loop works index (in object myobject = mylistofobjects[i] , index). there big difference between two: an index can access directly object based on position within list. an enumerator can access first element of list, , move next element (as described in previous link msdn). cannot access element directly, knowing index of element within list. so enumerator may seem less powerful, but: you don't know position of elements in group, because groups not ordered/indexed. you don't know number of elements in list (think linked list). even when it's o

how possible following : (i using mysql - phpmyadmin ) this query returns table name : select table_name table1 id = 1 i want use inside query , : select val (select table_name table1 id = 1) but sure not work, , since phpmyadmin not support calling stored procedures, there possible solution ? you cannot in single sql statement. you trying use data (field value) metadata (table name), , sql not allow this. you break in 2 statements or write dynamic sql in stored procedure. note not client layers support returning resultsets stored procedures.

i know people google have asked not put scrollable view inside scrollable view there official statement them directing not so? is close enough? you should never use horizontalscrollview listview, since listview takes care of own scrolling. importantly, doing defeats of important optimizations in listview dealing large lists, since forces listview display entire list of items fill infinite container supplied horizontalscrollview. http://developer.android.com/reference/android/widget/horizontalscrollview.html update: since may forced use 2 dimensional scrollview, may consider using this: internet archive of blog.gorges.us/2010/06/android-two-dimensional-scrollview/ i haven't used may reasonable approach.

in silverlight application want open xaml in new web browser. how can that? htmlpage.window.navigate aspx pages - maybe can convert xaml aspx? 10x! a xaml page cannot shown in browser window. silverlight showing silverlight program within < object > tag in aspx (or html) page; nothing more. in silverlight project, if chose host project in new web site, see second project both htm , aspx file hosts object links xap file. so basically, need create second silverlight project hosted in different aspx page. in main silverlight project can open new aspx page in new web browser window.

we study lot deadlocks in operating system courses. how occur ? or rather how there chance deadlock(the os doesn't let dead lock occur)? deadlocks occur program multi thread programs synchronizers , don't know you're doing. you have release mutex, example, before placing thread on wait long need same mutex awake thread, , that's small example.

hello i'm not sure if i'm understand following piece of code. glad if read explanations , correct me if i'm wrong. first of i'm declaring struct 3 arrays of char , integer. struct employee { char last[16]; char first[11]; char title[16]; int salary; }; after declare function takes 3 pointers char , integer value. function uses malloc() , sizeof() create struct on heap. creations of object on heap not clear me. when use struct employee* p = malloc(sizeof(struct employee)) , happens there exactly ? happens when use function struct employee* createemployee (char* last, char* first, char* title, int salary) several times different input. know pointer p isn't same pointer same struct on heap. rewrite information on heap, when use function several times? or create new object in different memory space? struct employee* createemployee(char*, char*, char*, int); struct employee* createemployee(char* last, char* first, char* title, int salary

i'm writing imap crawler, part of open source app, , incremental crawling i'd use message uids find out whether i've seen particular message or not. now found a post 2007 says imap uids aren't reliable. more specifically, if flag uidnotsticky set, can't assume uids same. question is, have take case uidnotsticky=true seriously, or imap servers non-sticky uids legacy stuff , not in (widespread) use anymore? if uidnotsticky response code returned during select or examine, you'll see uidvalidity value on mailbox (the imap term folder) changes every time select or examine mailbox. have check change in uidvalidity anyway since mailbox's uidvalidity not guaranteed immutable, , such change invalidates cached uids. yes, uidvalidity values generally don't change. code's going have deal case, , doing you'll have covered uidnotsticky case.

what difference between var regex = /\d/; and var regex = new regex("\d"); bob both evaluate same exact regex, first literal, meaning cannot use variables inside it, cannot dynamically generate regex. the second uses constructor explicitly , can used create dynamic regular expressions. var x = '3', r = ( new regexp( x + '\d' ) ); r.test('3d') the above example of dynamically constructing regex constructor, can not in literal form. in 99% of cases rely on first version ( literal ) regexpes in js. in advanced scenario need say, user input dynamically construct regex that's when you'll need second form. edit #1 : the first matches digit, second matches letter d . have double-escape second 1 in order equal first one, assume meant do. remember advice typed above accurate if second example new regexp('\d'). /\d/.test('3') // true ( new regexp('\d') ).test('3') // false ( new regexp('

i have mvvm wpf application, has 'user settings' injected view. these settings contain things last used search terms, or column widths on datagrids etc. works nicely , viewmodel unaware of these settings view specific , viewmodel may shared multiple views. these values bound in xaml of view. however, of settings have level of interference properties on viewmodel. an example: viewmodel has property of public int maxresults { get; set; } used limit number of results query brings back. when user changes value from, say, 100 50, ideally want saved in view's settings; enabling next time view used value 50 used rather 100. my first question: how can bind both view settings, , viewmodel property same element? thinking multi value converter, unsure of whether there funkier ways of performing operation. need both bindings 2 way, not horrible update loops. my second question: sometimes i'll want viewmodel take precedence on values supplied view settings. i&
