  • IE Information Bar, download file...how do I code for this?

    - by flatline
    I have a web page (asp.net) that compiles a package then redirects the user to the download file via javascript (window.location = ....). This is accompanied by a hard link on the page in case the redirect doesn't work - emulating the download process on many popular sites. When the IE information bar appears at the top due to restricted security settings, and a user clicks on it to download the file, it redirects the user to the page, not the download file, which refreshes the page and removes the hard link. What is the information bar doing here? Shouldn't it send the user to the location of the redirect? Am I setting something wrong in the headers of the download response, or doing something else wrong to send the file in the first place? C# Code: m_context.Response.Buffer = false; m_context.Response.ContentType = "application/zip"; m_context.Response.AddHeader("Content-Length", fs.Length.ToString()); m_context.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}_{1}.zip", downloadPrefix, DateTime.Now.ToString("yyyy-MM-dd_HH-mm"))); //send the file

Click here Anyway i have integrated this pluigin into my site and i have come across the following error message in my element inspector..Click here "TypeError: Object # has no method 'observe'" from the following code <script type="text/javascript"> document.observe('dom:loaded', function(evt) { var select, selects, _i, _len, _results; if (Prototype.Browser.IE && (Prototype.BrowserFeatures['Version'] === 6 || Prototype.BrowserFeatures['Version'] === 7)) { return; } selects = $$(".chzn-select"); _results = []; for (_i = 0, _len = selects.length; _i < _len; _i++) { select = selects[_i]; _results.push(new Chosen(select)); } deselects = $$(".chzn-select-deselect"); for (_i = 0, _len = deselects.length; _i < _len; _i++) { select = deselects[_i]; _results.push(new Chosen(select,{allow_single_deselect:true})); } return _results; }); </script> Does anyone know how i can solve this problem??

  • Quickly or concisely determine the longest string per column in a row-based data collection

    - by ccornet
    Judging from the failure of my last inquiry, I need to calculate and preset the widths of a set of columns in a table that is being made into an Excel file. Unfortunately, the string data is stored in a row-based format, but the widths must be calculated in a column-based format. The data for the spreadsheets are generated from the following two collections: var dictFiles = l.Items.Cast<SPListItem>().GroupBy(foo => foo.GetSafeSPValue("Category")).ToDictionary(bar => bar.Key); StringDictionary dictCols = GetColumnsForItem(l.Title); Where l is an SPList whose title determines which columns are used. Each SPListItem corresponds to a row of data, which are sorted into separate worksheets based on Category (hence the dictionary). The second line is just a simple StringDictionary that has the column name (A, B, C, etc.) as a key and the corresponding SPListItme field display name as the corresponding value. So for each Category, I enumerate through dictFiles[somekey] to get all the rows in that sheet, and get the particular cell data using SPListItem.Fields[dictCols[colName]]. What I am asking is, is there a quick or concise method, for any one dictFiles[somekey], to retrieve a readout of the longest string in each column provided by dictCols? If it is impossible to get both quickness and conciseness, I can settle for either (since I always have the O(n*m) route of just enumerating the collection and updating an array whenever strCurrent.Length strLongest.Length). For example, if the goal table was the following... Item# Field1 Field2 Field3 1 Oarfish Atmosphere Pretty 2 Raven Radiation Adorable 3 Sunflower Flowers Cute I'd like a function which could cleanly take the collection of items 1, 2, and 3 and output in the correct order... Sunflower, Atmosphere, Adorable Using .NET 3.5 and C# 3.0.

  • Script says Undefined

  • Getting the full-name of the current user, returns an empty string (C#/C++)

    - by Nir
    I try to get the full-name of the current log-in user (Fullname, not username). The following code C#, C++ works fine but on XP computers not connected to the Net, I get empty string as result if I run it ~20 minutes after login (It runs OK whithin the first ~20 minutes after login) A Win32 API (GetUserNameEx) is used rather that PrincipalContext since it PrincipalContext may takes up to 15 seconds when working offline.

  • How to test whether a char is NOT in a string? (java, junit)

    - by JB
    As title says, im having trouble with my junit tests passing for checking if a character is not in a string and how to check if an empty string doesnt have a character. here is the method i have: public static boolean isThere(String s, char value){ for(int x = 0; x <= s.length(); x++){ if(s.charAt(x) == value){ return true; } else if(s.length() == 0){ return false; } } return false; And here is the junit test: public void testIsThere() { { String sVal = "Jeff George"; boolean hasA = StringMethods.isThere(sVal,'e'); assertTrue(hasA); boolean hasE = StringMethods.isThere(sVal, 'o'); assertTrue(hasE); boolean notIn = StringMethods.isThere(sVal,'b'); assertTrue(notIn); } { String sVal = ""; boolean nothingIn = StringMethods.isThere(sVal,'a'); assertFalse(nothingIn); boolean notIn = StringMethods.isThere(sVal,'b'); assertFalse(notIn); } } Thank you very much, appreciated

  • Managing StringBuilder Resources

    - by Jim Fell
    My C# (.NET 2.0) application has a StringBuilder variable with a capacity of 2.5MB. Obviously, I do not want to copy such a large buffer to a larger buffer space every time it fills. By that point, there is so much data in the buffer anyways, removing the older data is a viable option. Can anyone see any obvious problems with how I'm doing this (i.e. am I introducing more performance problems than I'm solving), or does it look okay? tText_c = new StringBuilder(2500000, 2500000); private void AppendToText(string text) { if (tText_c.Length * 100 / tText_c.Capacity > 95) { tText_c.Remove(0, tText_c.Length / 2); } tText_c.Append(text); } EDIT: Additional information: In this application new data is received very rapidly (on the order of milliseconds) through a serial connection. I don't want to populate the multiline textbox with this new information so frequently because that kills the performance of the application, so I'm saving it to a StringBuilder. Every so often, the application copies the contents of the StringBuilder to the textbox and wipes out the StringBuilder contents.

  • jQuery / Loading content into div and changing url's (working but buggy)

    - by Bruno
    This is working, but I'm not being able to set an index.html file on my server root where i can specify the first page to go. It also get very buggy in some situations. Basically it's a common site (menu content) but the idea is to load the content without refreshing the page, defining the div to load the content, and make each page accessible by the url. One of the biggest problems here it's dealing with all url situations that may occur. The ideal would be to have a rel="divToLoadOn" and then pass it on my loadContent() function... so I would like or ideas/solutions for this please. Thanks in advance! //if page comes from URL if(window.location.hash != ''){ var url = window.location.hash; url = '..'+url.substr(1, url.length); loadContent(url); } //if page comes from an internal link $("a:not([target])").click(function(e){ e.preventDefault(); var url = $(this).attr("href"); if(url != '#'){ loadContent($(this).attr("href")); } }); //LOAD CONTENT function loadContent(url){ var contentContainer = $("#content"); //set load animation $(contentContainer).ajaxStart(function() { $(this).html('loading...'); }); $.ajax({ url: url, dataType: "html", success: function(data){ //store data globally so it can be used on complete window.data = data; }, complete: function(){ var content = $(data).find("#content").html(); var contentTitle = $(data).find("title").text(); //change url var parsedUrl = url.substr(2,url.length) window.location.hash = parsedUrl; //change title var titleRegex = /(.*)<\/title/.exec(data); contentTitle = titleRegex[1]; document.title = contentTitle; //renew content $(contentContainer).fadeOut(function(){ $(this).html(content).fadeIn(); }); }); }

  • Calling arrays from other methods in a different class

    - by Jake H
    Hello, I need help dealing with an array in my java program. in my first class, "test", I set 4 variables and then send them to my other class (test2). arr[i] = new test2(id, fname, lname, case); at that point, variables are set and then I want to return those variables. So in the test2 class, I have a method that strictly returns one of those variables public int getId(){ return id; } I understand this is a little stupid, but professor gets what professor wants I guess. What I want to do now is in my main method in "test" I want to retrieve that variable and sort the array based on that int. Unfortunately, I have to create my own sort function, but I think this would work for what I want to do. for(j = 0; j < arr.length; j++){ int indexMin =j; for(i = j; i < arr.length;i++){ if(arr[i] < arr[indexMin]){ indexMin = i; } } int tmp = arr[j]; arr[j] = arr[indexMin]; arr[indexMin] = tmp; } I appreciate any help anyone could provide. Thank you

  • What is the best practice for including jQuery ext functions?

    - by Metropolis
    Hey everyone, Currently I have a file that I named JQuery.ext.js which I am including in all of my pages. Inside this file I have numerous functions that do things like the following, (function($) { /** * Checks to see is the value inside ele is blank * @param message string The message that needs to be displayed if the element is blank * @return bool */ $.fn.isEmpty = function(message) { var b_IsEmpty = false; //Loop through all elements this.each(function() { //Check to see if an empty value is found if($(this).val().length <= 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsEmpty = true; return false; } return true; }); //Return false if the evaluation failed, otherwise return the jquery object so we can reuse it return (b_IsEmpty) ? true : false; }; /** * Checks to see if the value inside ele is numbers only * @param message string The message that needs to be displayed if the element is not numeric * @return bool */ $.fn.isNumeric = function(message) { var expression = /^[0-9]+$/; var b_IsNumeric = true; //Loop through elements checking each one this.each( function() { //Check to see if this value is not numeric if(!$(this).val().match(expression) && $(this).val().length > 0) { //If message is not blank if(message) { alert(message); $(this).focus().select(); } b_IsNumeric = false; } return b_IsNumeric; }); return b_IsNumeric; }; })(jQuery); Is there another way to do this? or is this the way most people do it? Thanks for any help, Metropolis

  • jQuery Suspected Naming Convention Problem

    - by donfigga
    Hi all, I'm having a problem with this jQuery function, the portion of the function that renames the id, class and name of the dropdown only works for the first dropdown, subsequent ones do not work, any ideas? I suspect it may have something to do with naming convention as in cat.parent_id but it is required for asp.net mvc model binding. $(document).ready(function () { $("table select").live("change", function () { var id = $(this).attr('id'); if ($(this).attr('classname') != "selected") { var rowIndex = $(this).closest('tr').prevAll().length; $.getJSON("/Category/GetSubCategories/" + $(this).val(), function (data) { if (data.length > 0) { //problematic portion $("#" + id).attr('classname', 'selected'); $("#" + id).attr('name', 'sel' + rowIndex); $("#" + id).attr('id', 'sel' + rowIndex); var position = ($('table').get(0)); var tr = position.insertRow(rowIndex + 1); var td1 = tr.insertCell(-1); var td2 = tr.insertCell(-1); td1.appendChild(document.createTextNode('SubCategory')); var sel = document.createElement("select"); sel.name = 'parent_id'; sel.id = 'parent_id'; sel.setAttribute('class', 'unselected'); td2.appendChild(sel); $('#parent_id').append($("<option></option>").attr("value", "-1").text("-please select item-")); $.each(data, function (GetSubCatergories, Category) { $('#parent_id').append($("<option></option>"). attr("value", Category.category_id). text(Category.name)); }); sel.name = 'cat.parent_id'; sel.id = 'cat.parent_id'; } }); } }); });

  • How to create Hash object/array using jquery?

    - by Patrick
    Hi folks I know there is a Hash() object in the Javascript prototype framework, but is there anything in Jquery like this? As I would like to stick with one javascript framework, rather than mixing the Prototype Frame work and the JQuery framework and use at the same time, as I worry there will be conflict and create side-effects. So my question is: how to create Hash object/array using jquery? Here is my function: /* prototype framework, I want to change this to jQuery! */ var starSaves = new Hash(); function myHover(id, pos) { var starStrip = $('star_strip_' + id); if (starSaves.keys().indexOf(id) == -1) { var starSave = new Array(); var imgs = starStrip.select("img") alert(imgs); for (var i = 0; i < imgs.length; i++) { starSave[starSave.length] = imgs[i].src; if (i < pos) imgs[i].src = "/images/star_1.gif"; else imgs[i].src = "/images/star_0.gif"; } starSaves.set(id, starSave); } }

  • Is there a more elegant solution than an if-statement with no else clause?

    - by Jay
    In the following code, if Control (the element that trigers Toggle's first OL) is not Visible it should be set Visible and all other Controls (Controls[i]) so be Hidden. .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ Reveal("hide",20,0.3,Controls[i]); }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Although the function [Toggle] works fine, it is actually setting Controls[i] to Hidden even if it is already. This is easily rectified by adding an If statement as in the code below, surely there is a more elegant solution, maybe a complex If condition? .js function Toggle(Control){ var Controls=document.getElementsByTagName("ol",document.getElementById("Quote_App")); var Control=Control.getElementsByTagName("ol")[0]; if(Control.style.visibility!="visible"){ for(var i=0;i<Controls.length;i++){ if(Controls[i]!=Control){ if(Controls[i].style.visibility=="visible"){ Reveal("hide",20,0.3,Controls[i]); }; }else{ Reveal("show",20,0.3,Control); }; }; }else{ Reveal("hide",20,0.3,Control); }; }; Your help is appreciated always.

    Hello, I have a dynamic chained select box that I am attempting to show the value of on a page load.

  • C# Convert string to nullable type (int, double, etc...)

    - by Nathan Koop
    I am attempting to do some data conversion. Unfortunately, much of the data is in strings, where it should be int's or double, etc... So what I've got is something like: double? amount = Convert.ToDouble(strAmount); The problem with this approach is if strAmount is empty, if it's empty I want it to amount to be null, so when I add it into the database the column will be null. So I ended up writing this: double? amount = null; if(strAmount.Trim().Length>0) { amount = Convert.ToDouble(strAmount); } Now this works fine, but I now have five lines of code instead of one. This makes things a little more difficult to read, especially when I have a large amount of columns to convert. I thought I'd use an extension to the string class and generic's to pass in the type, this is because it could be a double, or an int, or a long. So I tried this: public static class GenericExtension { public static Nullable<T> ConvertToNullable<T>(this string s, T type) where T: struct { if (s.Trim().Length > 0) { return (Nullable<T>)s; } return null; } } But I get the error: Cannot convert type 'string' to 'T?' Is there a way around this? I am not very familiar with creating methods using generics.

All is fine up until now BUT: the description of Commited Bytes Counter says that "Committed memory is the physical memory which has space reserved on the disk paging file(s)." I also read "Windows via C/C++ 5th edition" and this book says that commiting memory means reserving space in the page file.... The last two cases don't make sense to me... If you commit memory, doesn't that mean that you commit to physical storage (RAM)? The page file being there for swaping out currently unused pages of memory in case memory gets low. The book says that when you commit memory you actually reserve space in the paging file. If this were true than that would mean that for a committed page there is space reserved in the paging file and a page frame in physical in memory... So twice as much space is needed ?! Isn't the page file's purpose to make the total physical memory larger than it actually is? If I have a 1G of RAM with a 1G page file = 2G of usable "physical memory"(the book also states this but right after that it says what I discribed at point 2). What am I missing? Thanks.

    - by DanTransformer
    Ive got a jQuery navigation menu loading external content into my #main div, which works fine when the content is static, but the site im working on contains jQuery galleries/slideshows which id like to call into the div. The problem im having is when the gallery is loaded, the images all appear but the jQuery functionality does not work. Any help appreciated. here is the javascript im using... $(document).ready(function() { // Check for hash value in URL var hash = window.location.hash.substr(1); var href = $('#accordion ul li a').each(function(){ var href = $(this).attr('href'); if(hash==href.substr(0,href.length-5)){ var toLoad = hash+'.html #main'; $('#main').load(toLoad) } }); $('#accordion ul li a').click(function(){ var toLoad = $(this).attr('href')+' #main'; $('#main').hide('fast',loadContent); $('#load').remove(); $('#wrapper').append('<span id="load">LOADING...</span>'); $('#load').fadeIn('normal'); window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5); function loadContent() { $('#main').load(toLoad,'',showNewContent()) } function showNewContent() { $('#main').show('normal',hideLoader()); } function hideLoader() { $('#load').fadeOut('normal'); } return false; }); });

  • How to debug JBoss out of memory problem?

    - by user561733
    Hello, I am trying to debug a JBoss out of memory problem. When JBoss starts up and runs for a while, it seems to use memory as intended by the startup configuration. However, it seems that when some unknown user action is taken (or the log file grows to a certain size) using the sole web application JBoss is serving up, memory increases dramatically and JBoss freezes. When JBoss freezes, it is difficult to kill the process or do anything because of low memory. When the process is finally killed via a -9 argument and the server is restarted, the log file is very small and only contains outputs from the startup of the newly started process and not any information on why the memory increased so much. This is why it is so hard to debug: server.log does not have information from the killed process. The log is set to grow to 2 GB and the log file for the new process is only about 300 Kb though it grows properly during normal memory circumstances. This is information on the JBoss configuration: JBoss (MX MicroKernel) 4.0.3 JDK 1.6.0 update 22 PermSize=512m MaxPermSize=512m Xms=1024m Xmx=6144m This is basic info on the system: Operating system: CentOS Linux 5.5 Kernel and CPU: Linux 2.6.18-194.26.1.el5 on x86_64 Processor information: Intel(R) Xeon(R) CPU E5420 @ 2.50GHz, 8 cores This is good example information on the system during normal pre-freeze conditions a few minutes after the jboss service startup: Running processes: 183 CPU load averages: 0.16 (1 min) 0.06 (5 mins) 0.09 (15 mins) CPU usage: 0% user, 0% kernel, 1% IO, 99% idle Real memory: 17.38 GB total, 2.46 GB used Virtual memory: 19.59 GB total, 0 bytes used Local disk space: 113.37 GB total, 11.89 GB used When JBoss freezes, system information looks like this: Running processes: 225 CPU load averages: 4.66 (1 min) 1.84 (5 mins) 0.93 (15 mins) CPU usage: 0% user, 12% kernel, 73% IO, 15% idle Real memory: 17.38 GB total, 17.18 GB used Virtual memory: 19.59 GB total, 706.29 MB used Local disk space: 113.37 GB total, 11.89 GB used

  • In AS3/Flex, how can I get from flat data to hierarchical data?

    - by Dave S
    I have some data that gets pulled out of a database and mapped to an arraycollection. This data has a field called parentid, and I would like to map the data into a new arraycollection with hierarchical information to then feed to an advanced data grid. I think I'm basically trying to take the parent object, add a new property/field/variable of type ArrayCollection called children and then remove the child object from the original list and clone it into the children array? Any help would be greatly appreciated, and I apologize ahead of time for this code: private function PutChildrenWithParents(accountData : ArrayCollection) : ArrayCollection{ var pos_inner:int = 0; var pos_outer:int = 0; while(pos_outer < accountData.length){ if (accountData[pos_outer].ParentId != null){ pos_inner = 0; while(pos_inner < accountData.length){ if (accountData[pos_inner].Id == accountData[pos_outer].ParentId){ accountData.addItemAt( accountData[pos_inner] + {children:new ArrayCollection(accountData[pos_outer])}, pos_inner ); accountData.removeItemAt(pos_outer); accountData.removeItemAt(pos_inner+1); } pos_inner++; } } pos_outer++; } return accountData; }
