i know how setting proxy manually , use in webview. settings -> wireless networks ->mobile networks-> access point names->telkila. enter proxy server address , port (which 80). webview.enableplatformnotifications(); but can set proxy setting code? user didn't have set manually? thanks there no legal way change webview proxy settings programmatically. it's possible use java reflection change mproxyhost value android.net.http.requestqueue class. it's private value , there no setters it, reflection seems possible variant. used in project , works. here sample of method: private boolean setproxyhostfield(httphost proxyserver) { // getting network class networkclass = null; object network = null; try { networkclass = class.forname("android.webkit.network"); field networkfield = networkclass.getdeclaredfield("snetwork"); network = getfieldvaluesafely(networkfield, null); } ca

hi i'm trying row count table using watin ie 1.get table (done) 2.count rows in table (not done) 3.compare count (already have idea) how row count table,using watin?any ideas?can point me right direction hi guys;thanks helping,i hit roadblock here i'm using this int countnumberofrows = this.elements.joblistinggrid.owntablerows .skip(1) .where(r => !r.classname.contains("rowhidden")) .count(); ok i'm able count '21' :),my problem page using same control,and number of row each page same if click activelink rows 21 , if click on pendinglink although rows hidden still 21.i need differentiate number of rows because way me this if (countnumberofrows != 0) { this.elements.activelink.click(); } else { this.elements.pendinglink.click(); } is idea possible?or need @ way if have table tablerows collection gives number of rows:

i've got code: protected void ddltemplate_selectedindexchanged(object sender, eventargs e) { template t = new template(); t.loadbyid(convert.toint32(ddltemplate.selecteditem.value)); foreach (widget w in t.templatewidgets) { usercontrols_widget ucwidget = (usercontrols_widget)loadcontrol("~/usercontrols/ucwidget.ascx"); ucwidget.widgettitle = w.name; ucwidget.parameters = w.parameters; pnlwidgets.controls.add(ucwidget); } } protected void lnksubmit_click(object sender, eventargs e) { foreach (control cc in pnlwidgets.controls) { } } basically i'd foreach widgets added page in ddltemplate_selectedindexchanged event. question how usercontrols added. you can add usercontrols list<usercontrols_widget> , loop through instead of looping through controls on page.

edit: clarify - asking advice on both unit testing and user interface testing. currently, don't use tdd. while developing application testing working on. testing iteration minor function changes entire models. try not code before test. instant feedback. of course, experience can see potential problems or bugs occurring i'm coding. but, after application complete go through entire app on frontend , ensure functions working expected. means literally everything. every add/edit/delete, sort, filter, broken links , such. this can take lot of time ensure work hardly ever contains bugs after deployment. however, i'm looking more standard solution. experienced developers do? assume moment single developer , not have testing department etc do hire beta testers (no if app sensitive public use)? is viable build series of 'general' unit tests can example test sorting, filter functions. 1 testing add/edit/delete functions. love hear feedback. changing way de

i trying change document content type. must use workflow, , best way workflow create in sharepoint desingner. know how programatical in visual studio i know old question, figured out: you can using spd workflow (spd 2007 or 2010). can call content type field in 2 ways: in workflow, use "if [field] equals [value]" or "set [field] [value]" for "if" statement, field called "content type". "set" statement field called "content type id". in either case can assign value based on available content types. you need enable content types on list or library settings. here's example workflow based on custom list record accounts payable entries: list column: request type (choice column choices of reimbursement, department expense, other) list content types: default, accounts payable, accounts receivable if [request type] equals [reimbursement] set [content type id] [accounts payable] when workflow fires, se

what regular expression od -0d -123d -145y 234w , not +234d or -678m etc. i have string exp_regex_valid_literal = @"[0-9]*[d|d|w|w|m|m|q|q|y|y]"; regex regex = new regex(exp_regex_valid_literal); return regex.ismatch(inputstring); but failing "/0345d" validation rules: the expression alphanumeric one(where alphabets optional) alphabets can d|d|w|w|m|m|q|q|y|y , can appear after numerals. if character can come before numerals can minus.so -123 valid or -123d or 123d or 123w valid. not 23dw or +12d etc. thanks if understand want, may work: /^-?\d+[dwmqy]$/i c# syntax (not quite sure): regex.match("/0123d", "^-?\d+[dwmqy]$",regexoptions.ignorecase); where: ^ begining of string -? optionnal - \d+ 1 or more digits [dwmqy] 1 of these char $ end of string case insensitive

there easy solution this, can't figure out. looking to: take csv file array loop through array , split fields variables if array field empty set variable "n/a" note: setting $variable " n/a " cannot working. for example: foreach $var (@list) { ($name,$date,$size, etc...)=split(/,\"/,$var); } how set $date " n/a " if field in array empty? so produce: $name = jim $date = n/a $size = small i hope makes sense , easy fix. -thanks assuming variable $date undefined when "empty": if (!defined($date)) { $date = 'n/a'; } or more concisely: $date //= 'n/a'; or if empty string, i.e. $date = ''; (this work in case $date undefined, don't want use if only want identify case undefined): if ($date eq '') { $date = 'n/a'; } or more concisely (note set $date n/a if $date '0' due perl's weak typing): $date ||= 'n/a';

hi i'm trying check if html element scrollable.only gecko support needed (and webkit support nice not necessary). documentation tells scrollheight , clientheight same when element has no vertical scrollbar https://developer.mozilla.org/en/dom/element.scrollheight discovered gecko adds margin size scrollheight. so, element margins, scrollheight superior clientheight. https ://bugzilla.mozilla.org/show_bug.cgi?id=576976#c2 so, use like: var clientheight = element.clientheight; var bordertop = window.getcomputedstyle(element,null).getpropertyvalue('border-top-width'); var borderbottom = window.getcomputedstyle(element,null).getpropertyvalue('border-bottom-width'); var scrollheight = element.scrollheight - parseint(bordertop, 10) - parseint(borderbottom, 10); it works fine except in 1 case: when use firefox zoom. let's have border of 1px around element. clientheight , scrollheight have difference of 2px (1 top, 1 bottom). unfortunately, window.getcompute

i'm trying create animation link 2 position of view. position of view defined overridden method onlayout. i'm getting position before , after position update getlocationonscreen method. here code simplified: int[] startposition = new int[2]; view.getlocationonscreen(startposition); // layout update changed view position on screen requestlayout(); invalidate(); int[] endposition = new int[2]; view.getlocationonscreen(endposition); animation anim = new translateanimation(startposition[0], endposition[0], startposition[1], endposition[1]); anim.setduration(100); view.startanimation(anim); the problem onlayout method isn't called after layout update , call requestlayout... found calling requestlayout schedule layout pass of view tree. question is: how make layout calculation synchronously ? or wait end ? use postdelayed or add event system onlayout method, i'd test cleaner methods first... call onlayout method myself, don't know how calculate arguments.

what difference between mysql-5.5.8.zip , mysql-5.5.8-win32.zip in http://dev.mysql.com/downloads/mysql/ download page. have win 2k environment, binary should use , why have huge size difference between above? the smaller package not contain test suite , embedded server. anyway, suggest use msi installer instead - installation , configuration way more straightforward.
