  • Check whether a folder is a local or a network resource in .NET

    - by rwmnau
    Is there a quick way to check whether a path I have is on a local disk or somewhere on the network? I can't just check to see if it's a drive letter vs. UNC, because that would incorrectly identify mapped drives as local. I assumed it would be a boolean in the DirectoryInfo object, but it appears that it's not. I've found classic VB code to do this check (through an API), but nothing for .NET so far.

  • Implementing hoverIntent for Drop Down Menu (coming from click_event)

    - by stormeTrooper
    I've just recently started programming, I was hoping for some help. I have a drop down menu that was originally activated by click_event, however I want to now implement hoverIntent in order to make the menu drop. The issue I am having now is being able to use the menu, because whenever I invoke the menu now, once I leave the area that activates the menu, the menu closes. If you could explain to me like I'm five, I'd appreciate it, thanks :) The code I am using as follows: JavaScript: function setupUserConfigMenu() { $('.user_profile_btn').hoverIntent( function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }, function (event) { $('#user_settings_dropdown').animate({height:['toggle', 'swing'] }, 225); }) } HTML: <li> <a href="<%= "#" %>" class="user_profile_btn" title="Your profile page"><%= truncate(current_user.full_name || current_user.name, :length => 28) %> <div class="arrow_down"></div></a> <ul id="user_settings_dropdown"> <li> <a href="<%= current_user.get_url(true) %>"> <%= image_tag current_user.get_thumb_url, :size => "30x30" %> <div> <%= truncate(current_user.full_name || current_user.name, :length => 40) %> <br> View profile </div> </a> </li> <div class="grey_line"></div> <li class="settings_list_item"> <%= link_to "Settings", edit_user_registration_path %> </li> <li class="settings_list_item"> <%= link_to "About", "/about" %> </li> <li class="settings_list_item"> <%= link_to "Logout", destroy_user_session_path, :method => :delete %> </li> </ul> </li>

  • Difference between Cloud and Virtualization

    - by Akash Kava
    Ops: This does not belong to ServerFault because it focuses on Programing Architecture. I have following questions regarding differences between Cloud and Virtualization.. How Cloud is different then Virtualization? Currently I tried to find out pricing of Rackspace, Amazone and all similar cloud providers, I found that our current 6 dedicated servers came cheaper then their pricing. So how one can claim cloud is cheaper? Is it cheaper only in comparison of normal hosting? We re organized our infrastructure in virtual environment to reduce or configuration overhead at time of failure, we did not have to rewrite any peice of code that is already written for earlier setup. So moving to virtualization does not require any re programming. But cloud is absoltely different and it will require entire reprogramming right? Is it really worth to recode when our current IT costs are 3-4 times lower then cloud hosting including raid backups and all sort of clustering for high availability? New programming architecture means new overheads of training staff, new methods of testing and new deployment schemes, does it justify over "on demand resource usage" words of cloud? We are having current development architecture with simple Server side ASP.NET WebServices with no local context and on client side Flex/Silverlight which offers pretty good REST architecture and its highly scalable. How does cloud differs from REST model of deployment? On storage, SQL Server or MySQL offers pretty good replication and high availibility then what is advantage in cloud? Data guarantee, one of our vendor hosting some other customer's app on cloud (one of most used), lost Entire Hard Disk (the virtual) and entire module in first 6 months. Second provider said its your duty to take backup, fine I agree, but no provider gives SLA for data guarantee, they give 99% uptime. However in most business apps, uptime is less important then data integrity. In our 10 years of dedicated hosting experience we had only one hard disk crash. This makes me little skeptical to go for cloud and loosing control over data. And I feel its just a big marketing buzz to sell virtulization in different form. Size of data, currently all providers charge very heavy for large data, if you are hosting only below 100GB cloud can be good alternative, but I think virtual servers and dedicated servers above 100GB to few TBs are still cheaper. Why would want to pay so high on cloud when there is no data guarentee as well as it doesnt say anything about redundancy. (I wish SO had something for spell check for Internet Explorer, sorry for wrong spellings in my post)

    - by marbrun
    Hello There are 2 arrays, both with the same length and with the same keys: $a1 = [1=>2000,65=>1354,103=>1787]; $a2 = [1=>'hello',65=>'hi',103=>'goodevening']; asort($a1); The keys of a1 and a2 are id's from a database. a1 gets sorted by value. Once sorted, how can we use the same sorting order in a2? Thanks!

  • NServicebus DNS Entry for Machine location

    - by Paul Oakham
    Hi Guys, I am trying to use a DNS entry for my NServicebus queue endpoint but no messages are being sent. It works fine when I enter the computer name or an IPAddress. I can ping the record and it resolves correctly so i'm wondering if it is possible to use a DNS record? Here is my config: <MessageEndpointMappings> <!--These are the messages which need to be sent to the BusService --> <add Messages="BusCommon.BusHeartBeatMessage, BusCommon" Endpoint="[email protected]" /> </MessageEndpointMappings> Thanks

  • What is a good generic sibling control Javascript communication strategy?

    - by James
    I'm building a webpage that is composed of several controls, and trying to come up with an effective somewhat generic client side sibling control communication model. One of the controls is the menu control. Whenever an item is clicked in here I wanted to expose a custom client side event that other controls can subscribe to, so that I can achieve a loosely coupled sibling control communication model. To that end I've created a simple Javascript event collection class (code below) that acts as like a hub for control event registration and event subscription. This code certainly gets the job done, but my question is is there a better more elegant way to do this in terms of best practices or tools, or is this just a fools errand? /// Event collection object - acts as the hub for control communication. function ClientEventCollection() { this.ClientEvents = {}; this.RegisterEvent = _RegisterEvent; this.AttachToEvent = _AttachToEvent; this.FireEvent = _FireEvent; function _RegisterEvent(eventKey) { if (!this.ClientEvents[eventKey]) this.ClientEvents[eventKey] = []; } function _AttachToEvent(eventKey, handlerFunc) { if (this.ClientEvents[eventKey]) this.ClientEvents[eventKey][this.ClientEvents[eventKey].length] = handlerFunc; } function _FireEvent(eventKey, triggerId, contextData ) { if (this.ClientEvents[eventKey]) { for (var i = 0; i < this.ClientEvents[eventKey].length; i++) { var fn = this.ClientEvents[eventKey][i]; if (fn) fn(triggerId, contextData); } } } } // load new collection instance. var myClientEvents = new bsdClientEventCollection(); // register events specific to the control that owns it, this will be emitted by each respective control. myClientEvents.RegisterEvent("menu-item-clicked"); Here is the part where this code above is consumed by source and subscriber controls. // menu control $(document).ready(function() { $(".menu > a").click( function(event) { //event.preventDefault(); myClientEvents.FireEvent("menu-item-clicked", $(this).attr("id"), null); }); }); <div style="float: left;" class="menu"> <a id="1" href="#">Menu Item1</a><br /> <a id="2" href="#">Menu Item2</a><br /> <a id="3" href="#">Menu Item3</a><br /> <a id="4" href="#">Menu Item4</a><br /> </div> // event subscriber control $(document).ready(function() { myClientEvents.AttachToEvent("menu-item-clicked", menuItemChanged); myClientEvents.AttachToEvent("menu-item-clicked", menuItemChanged2); myClientEvents.AttachToEvent("menu-item-clicked", menuItemChanged3); }); function menuItemChanged(id, contextData) { alert('menuItemChanged ' + id); } function menuItemChanged2(id, contextData) { alert('menuItemChanged2 ' + id); } function menuItemChanged3(id, contextData) { alert('menuItemChanged3 ' + id); }

  • c++ std::ostringstream vs std::string::append

    - by NickSoft
    In all examples that use some kind of buffering I see they use stream instead of string. How is std::ostringstream and << operator different than using string.append. Which one is faster and which one uses less resourses (memory). One difference I know is that you can output different types into output stream (like integer) rather than the limited types that string::append accepts. Here is an example: std::ostringstream os; os << "Content-Type: " << contentType << ";charset=" << charset << "\r\n"; std::string header = os.str(); vs std::string header("Content-Type: "); header.append(contentType); header.append(";charset="); header.append(charset); header.append("\r\n"); Obviously using stream is shorter, but I think append returns reference to the string so it can be written like this: std::string header("Content-Type: "); header.append(contentType) .append(";charset=") .append(charset) .append("\r\n"); And with output stream you can do: std::string content; ... os << "Content-Length: " << content.length() << "\r\n"; But what about memory usage and speed? Especially when used in a big loop. Update: To be more clear the question is: Which one should I use and why? Is there situations when one is preferred or the other? For performance and memory ... well I think benchmark is the only way since every implementation could be different. Update 2: Well I don't get clear idea what should I use from the answers which means that any of them will do the job, plus vector. Cubbi did nice benchmark with the addition of Dietmar Kühl that the biggest difference is construction of those objects. If you are looking for an answer you should check that too. I'll wait a bit more for other answers (look previous update) and if I don't get one I think I'll accept Tolga's answer because his suggestion to use vector is already done before which means vector should be less resource hungry.

  • Javascript terminates after trying to select data from an object passed to a function

    - by Silmaril89
    Here is my javascript: $(document).ready(function(){ var queries = getUrlVars(); $.get("mail3.php", { listid: queries["listid"], mindex: queries["mindex"] }, showData, 'html'); }); function showData(data) { var response = $(data).find("#mailing").html(); if (response == null) { $("#results").html("<h3>Server didn't respond, try again.</h3>"); } else if (response.length) { var old = $("#results").html(); old = old + "<br /><h3>" + response + "</h3>"; $("#results").html(old); var words = response.split(' '); words[2] = words[2] * 1; words[4] = words[4] * 1; if (words[2] < words[4]) { var queries = getUrlVars(); $.get("mail3.php", { listid: queries["listid"], mindex: words[2] }, function(data){showData(data);}, 'html'); } else { var done = $(data).find("#done").html(); old = old + "<br />" + done; $("#results").html(old); } } else { $("#results").html("<h3>Server responded with an empty reply, try again.</h3>"); } } function getUrlVars() { var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for (var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; } After the first line in showData: var response = $(data).find("#mailing").html(); the javascript stops. If I put an alert before it, the alert pops up, after it, it doesn't pop up. There must be something wrong with using $(data), but why? Any ideas would be appreciated.

  • How to time Java program execution speed

    - by George Mic
    Sorry if this sounds like a dumb question but how do you time the execution of a java program? I'm not sure what class I should use to do this. I'm kinda looking for something like: //Some timer starts here for (int i = 0; i < length; i++) { // Do something } //End timer here System.out.println("Total execution time: " + totalExecutionTime); Thanks

  • vim unicode bufread/bufwrite script

    - by anon
    Problem: I want my unicode characters to be stored on disk as (rather tan utf8/16 encoding) \u#### However, I want them dispalyed as unicode characters when opened up in vim. I think the easiest way to acheive this is some bufopen/bufwrite script that automatically: on opening, convert \u#### to unicode character on writing, convert unicode characters into \u#### However, I don't know what functions to call to make this happen. Can someone lend a hand? Thanks!

  • How to handle set based consistency validation in CQRS?

    - by JD Courtoy
    I have a fairly simple domain model involving a list of Facility aggregate roots. Given that I'm using CQRS and an event-bus to handle events raised from the domain, how could you handle validation on sets? For example, say I have the following requirement: Facility's must have a unique name. Since I'm using an eventually consistent database on the query side, the data in it is not guaranteed to be accurate at the time the event processesor processes the event. For example, a FacilityCreatedEvent is in the query database event processing queue waiting to be processed and written into the database. A new CreateFacilityCommand is sent to the domain to be processed. The domain services query the read database to see if there are any other Facility's registered already with that name, but returns false because the CreateNewFacilityEvent has not yet been processed and written to the store. The new CreateFacilityCommand will now succeed and throw up another FacilityCreatedEvent which would blow up when the event processor tries to write it into the database and finds that another Facility already exists with that name.

  • Multiple word Auttosuggest using Lucene.Net

    - by eric
    I am currently working on an search application which uses Lucene.Net to index the data from the database to Index file. I have a product catalog which has Name, short and long description, sku and other fields. The data is stored in Index using StandardAnalyzer. I am trying to add auto suggestion for a text field and using TermEnum to get all the keyword terms and its score from the Index. But the terms returned are of single term. For example, if I type for co, the suggestion returned are costume, count, collection, cowboy, combination etc. But I want the suggestion to return phrases. For exmaple, if I search for co, the suggestions should be cowboy costume, costume for adults, combination locks etc. The following is the code used to get the suggestions: public string[] GetKeywords(string strSearchExp) { IndexReader rd = IndexReader.Open(mIndexLoc); TermEnum tenum = rd.Terms(new Term("Name", strSearchExp)); string[] strResult = new string[10]; int i = 0; Dictionary<string, double> KeywordList = new Dictionary<string, double>(); do { //terms = tenum.Term(); if (tenum.Term() != null) { //strResult[i] = terms.text.ToString(); KeywordList.Add(tenum.Term().text.ToString(), tenum.DocFreq()); } } while (tenum.Next() && tenum.Term().text.StartsWith(strSearchExp) && tenum.Term().text.Length > 1); var sortedDict = (from entry in KeywordList orderby entry.Value descending select entry); foreach (KeyValuePair<string, double> data in sortedDict) { if (data.Key.Length > 1) { strResult[i] = data.Key; i++; } if (i >= 10) //Exit the for Loop if the count exceeds 10 break; } tenum.Close(); rd.Close(); return strResult; } Can anyone please give me directions to achive this? Thanks for looking into this.

  • has anyone produced an in-memory GIT repository?

    - by Andrew Matthews
    I would like to be able to take advantage of the benefits of GIT (and its workflows), but without the cost of disk access - I just would like to leverage the distributed revision control capabilities of GIT to produce something like a hybrid of memcached and GIT. (preferably in .NET) Is there such a beast out there?

  • Replace Components.classesByID with document.implementation.createDocument

    - by Earl Smith
    I am not the author of this code, but it is no longer maintained. So I am trying to fix it, but I have very little experience in javascript. Since Firefox 9, Components.classesByID["{3a9cd622-264d-11d4-ba06-0060b0fc76dd}"]. has been obsolete. Instead, it is suggested that document.implementation.createDocument be used. Can someone here show me how to implement these changes? I seem to be, just banging my head with everything I have tried. The example given at Mozilla developer network is: var doc = document.implementation.createDocument ("http://www.w3.org/1999/xhtml", "html", null); var body = document.createElementNS("http://www.w3.org/1999/xhtml", "body"); body.setAttribute("id", "abc"); doc.documentElement.appendChild(body); alert(doc.getElementById("abc")); // [object HTMLBodyElement] and the code in the .jsm I am trying to fix is: this.fgImageData = {}; this.fgImageData["check"] = [ " *", " **", "* ***", "** *** ", "***** ", " *** ", " * "]; this.fgImageData["radio"] = [ " **** ", "******", "******", "******", "******", " **** "]; this.fgImageData["menu-ltr"] = [ "* ", "** ", "*** ", "****", "*** ", "** ", "* "]; this.fgImageData["menu-rtl"] = [ " *", " **", " ***", "****", " ***", " **", " *"]; // I think I'm doing something slightly wrong when creating the document // but I'm not sure. It works though. *FIX* var domi = Components.classesByID["{3a9cd622-264d-11d4-ba06-0060b0fc76dd}"]. createInstance(Components.interfaces.nsIDOMDOMImplementation); this.document = domi.createDocument("http://www.w3.org/1999/xhtml", "html", null); this.canvas = this.document.createElementNS("http://www.w3.org/1999/xhtml", "html:canvas"); for(var name in this.fgImageData) { if (this.fgImageData.hasOwnProperty(name)) { var data = this.fgImageData[name]; var width = data[0].length; var height = data.length; this.canvas.width = width; this.canvas.height = height; var g = this.canvas.getContext("2d"); g.clearRect(0, 0, width, height); var idata = g.getImageData(0, 0, width, height); for(var y=0, oy=0; y<height; y++, oy+=idata.width*4) for(var x=0, ox=oy; x<width; x++, ox+=4) idata.data[ox+3] = data[y][x] == " " ? 0 : 255; this.fgImageData[name] = idata; } } },

  • Why are joins bad when considering scalability?

    - by acidzombie24
    Why are joins bad or 'slow'. I know i heard this more then once. I found this quote The problem is joins are relatively slow, especially over very large data sets, and if they are slow your website is slow. It takes a long time to get all those separate bits of information off disk and put them all together again. source I always thought they were fast especially when looking up a PK. Why are they 'slow'?
