  • install remote desktop in a PC with FTP and HTTP access

    - by user39862
    Hi, I have a machine behind a firewall to which I have only FTP and HTTP access - is there any remote desktop software available that I can install over FTP and access over HTTP (java based perhaps)? The reason I'm asking is because ultraVNC stopped working for no reason and I need to access the PC (it has installed windows 7 with UAC disabled). thanks

  • Suggestions for jQuery-based Date/Time Selector

    - by Jason Palmer
    Hi everyone, I'm in search for a jQuery-based Date/Time Selector. I have found a few that are quite nice, but one of my requirements is that I can provide a json/xml/etc source of available days/times and the control should only allow selections of available days/times. Is anyone aware of a plugin that does this, or at least a plugin that could be modified to do this? Thanks!

  • Check if a GtkEntryCompletion is currently visible

    - by Joe
    I have a GtkEntry with a GtkEntryCompletion attached to it. The Entry does something fairly expensive if the user hasn't changed the text in it for a second (to preview search results). However it's very common for the user to stop typing in order to select the correct autocompletion. So I'd like to delay the preview until the user has stopped typing and the GtkEntryCompletion is not currently suggesting anything. GtkEntryCompletion is not a real widget however, and doesn't seem to have any way to get to whatever widget does own the CellRenderers it uses. Is there a way I can detect if it's visible or not?

  • Sorted directory size display in Unix

    - by Srikanth M
    How do i display directory sizes in a sorted manner in Unix while listing only innermost sub-directories? For example, I don't want to something like this - 100270480 /a/b/BP/b/bat/qc3 100270416 /a/b/BP/b/bat/qc3/logs 99020464 /a/b/BP/b/bat/qc3/logs/i 99005456 /a/b/BP/b/bat/qc5 99005408 /a/b/BP/b/bat/qc5/logs 97726832 /a/b/BP/b/bat/qc5/logs/i I just want - 99020464 /a/b/BP/b/bat/qc3/logs/i 97726832 /a/b/BP/b/bat/qc5/logs/i

  • Running DllImport commands from CreateRemoteThread

    - by Gbps
    I have a function named Msg that's imported from a dll named tier0.dll. I can DllImport this just fine, but the command only works when the dll is attached to another process which can complete the Msg command. Using CreateRemoteThread, it is possible that I could call Msg using C# while still letting it have access to the variables of the attached process it needs to complete the command? Thanks!

  • How do I load content with ujs, jquery and rails?

    - by Joseph Silvashy
    I'm trying to figure out the best way to insert content into a light box using rails UJS. I have a link that looks like this: <%= link_to "login", login_path, :remote => true %> Which produces html as such: <a data-remote="true" href="/login">login</a> So this all works great, and I've created the view file: user_sessions/new.js.erb which also loads just fine, but my question what is the preferred method of inserting appending the html into the page? Like I already have the login form on the non-js page, so can't I just load that partial into the page? Any ideas would be very welcomed.

  • WPF: How do I bind a Control to a formula composed of several dependency properties?

    - by Pablo
    Hi all, I'm working on Expression Blend and I'm currently designing a custom control which has a Grid with 5 rows inside, and also has two Dependency properties: "Value", and "Maximum". Three of the rows have fixed height, and what I'm trying to do is set the remaining rows height to "Value/Maximum" and "1-Value/Maximum" respectively. How do I go and do that? When I set the height to "Value" it seems to react, but when I go and set it to "Value/Maximum" it stops working. I'm still a bit new around WPF, so there must be another way to achieve what I'm intending, but after searching I couln't find my problem elsewhere. Code: <Grid x:Name="LayoutRoot" Width="Auto" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="32"/> <RowDefinition Height="{Binding Path=(Value/Maximum), ElementName=UserControl, Mode=Default}"/> <RowDefinition Height="16"/> <RowDefinition Height="{Binding Path=(1-Value/Maximum), ElementName=UserControl, Mode=Default}"/> <RowDefinition Height="32"/> </Grid.RowDefinitions> (...) By the way, Value is always a not negative double less than or equal to Maximum; so the result of the division will be number between 0.0 a 1.0. I want a "star" instead of "pixel" row height.

  • CPU-adaptive compression

    - by liori
    Hello, Let assume I need to send some data from one computer to another, over a pretty fast network... for example standard 100Mbit connection (~10MB/s). My disk drives are standard HDD, so their speed is somewhere between 30MB/s and 100MB/s. So I guess that compressing the data on the fly could help. But... I don't want to be limited by CPU. If I choose an algorithm that is intensive on CPU, the transfer will actually go slower than without compression. This is difficult with compressors like GZIP and BZIP2 because you usually set the compression strength once for the whole transfer, and my data streams are sometimes easy, sometimes hard to compress--this makes the process suboptimal because sometimes I do not use full CPU, and sometimes the bandwidth is underutilized. Is there a compression program that would adapt to current CPU/bandwidth and hit the sweet spot so that the transfer will be optimal? Ideally for Linux, but I am still curious about all solutions. I'd love to see something compatible with GZIP/BZIP2 decompressors, but this is not necessary. So I'd like to optimize total transfer time, not simply amount of bytes to send. Also I don't need real time decompression... real time compression is enough. The destination host can process the data later in its spare time. I know this doesn't change much (compression is usually much more CPU-intensive than decompression), but if there's a solution that could use this fact, all the better. Each time I am transferring different data, and I really want to make these one-time transfers as quick as possible. So I won't benefit from getting multiple transfers faster due to stronger compression. Thanks,

  • Render MVCContrib Grid with No Header Row

    - by Ben Griswold
    The MVCContrib Grid allows for the easy construction of HTML tables for displaying data from a collection of Model objects. I add this component to all of my ASP.NET MVC projects.  If you aren’t familiar with what the grid has to offer, it’s worth the looking into. What you may notice in the busy example below is the fact that I render my column headers independent of the grid contents.  This allows me to keep my headers fixed while the user searches through the table content which is displayed in a scrollable div*.  Thus, I needed a way to render my grid without headers. That’s where Grid Renderers come into play.  <table border="0" cellspacing="0" cellpadding="0" class="projectHeaderTable">     <tr>         <td class="memberTableMemberHeader">             <%= Html.GridColumnHeader("Member", "Index", "MemberFullName")%>              </td>         <td class="memberTableRoleHeader">             <%= Html.GridColumnHeader("Role", "Index", "ProjectRoleTypeName")%>              </td>                <td class="memberTableActionHeader">             Action         </td>     </tr> </table> <div class="scrollContentWrapper"> <% Html.Grid(Model)     .Columns(column =>             {                 column.For(c => c.MemberFullName).Attributes(@class => "memberTableMemberCol");                 column.For(c => c.ProjectRoleTypeName).Attributes(@class => "memberTableRoleCol");                 column.For(x => Html.ActionLink("View", "Details", new { Id = x.ProjectMemberId }) + " | " +                                 Html.ActionLink("Edit", "Edit", new { Id = x.ProjectMemberId }) + " | " +                                 Html.ActionLink("Remove", "Delete", new { Id = x.ProjectMemberId }))                     .Attributes(@class => "memberTableActionCol").DoNotEncode();             })     .Empty("There are no members associated with this project.")     .Attributes(@class => "lbContent")     .RenderUsing(new GridNoHeaderRenderer<ProjectMemberDetailsViewModel>())     .Render(); %> </div> <div class="scrollContentBottom">     <!– –> </div> <%=Html.Pager(Model) %> Maybe you noticed the reference to the GridNoHeaderRenderer class above?  Yep, rendering the grid with no header is straightforward.   public class GridNoHeaderRenderer<T> :     HtmlTableGridRenderer<T> where T: class {     protected override bool RenderHeader()     {         // Explicitly returning true would suppress the header         // just fine, however, Render() will always assume that         // items exist in collection and RenderEmpty() will         // never be called.           // In other words, return ShouldRenderHeader() if you         // want to maintain the Empty text when no items exist.         return ShouldRenderHeader();     } } Well, if you read through the comments, there is one catch.  You might be tempted to have the RenderHeader method always return true.  This would work just fine but you should return the result of ShouldRenderHeader() instead so the Empty text will continue to display if there are no items in the collection. The GridRenderer feature found in the MVCContrib Grid is so well put together, I just had to share.  * Though you can find countless alternatives to the fixed headers problem online, this is the only solution that I’ve ever found to reliably work across browsers. If you know something I don’t, please share.

  • How can I prevent Telerik RadChart from generating an onerror attribute?

    - by Sean McMillan
    We're using the Telerik Rad Controls for ASP.Net Ajax on an ASP.Net MVC project. The RadChart generates the following HTML: <img onerror="if(confirm('Error loading RadChart image.\nYou may also wish to check the ASP.NET Trace for further details.\nDisplay stack trace?'))window.location.href=this.src;" src="ChartImage.axd?UseSession=true&amp;ChartID=e25ad666-e05b-4a92-ac0c-4f2c729b9382_chart_ctl00$MainContent$AverageCTMChart&amp;imageFormat=Png&amp;random=0.501658702968461" usemap="#imctl00_MainContent_AverageCTMChart" style="border-width: 0px;" alt=""> I'd like to remove the onerror attribute; I don't really want the customers being offered the option to see a stack trace if something goes wrong. I can't see any way to control the markup that this control generates. Google searches provide no help. Has anyone dealt with this before? How do I remove the onerror attribute?

  • setsockopt TCP_NODELAY question on Windows Mobile

    - by weki
    Hi all, I have a problem on Windows Mobile 6.0. I would like to create a TCP connection which does not use the Nagle algorithm, so it sends my data when I call "send" function, and does not buffer calls, having too small amount of data. I tried the following: BOOL b = TRUE; setsockopt(socketfd, IPPROTO_TCP, TCP_NODELAY, (char*)(&b), sizeof(BOOL)); It works fine on desktop. But on Windows Mobile, if I set this value, than I make a query for it, the returned value is 8. And the network traffic analysis shows that the nothing changed. Is there any way to force a flush to my socket?

  • My mental block - struggling to learn Objective C

    - by iqessar
    Hello people, this would be my first question after signing up! Anyway heres my question, I did Java at university and I was always told I am a good programmer. However I never pursued it as a career - I went into support and management instead. Im pretty much bored with my job, I have therefore started to learn Objective C so that I can develop apps for the iphone. I am currently watching several different Videos / Books. My problem is that when I go through the Apple documentation, although I understand most of it, sometimes I stumble. I believe that because you/we have the Apple documentation (i.e. Framework references) , everything should be clear, and therefore you should have no need to refer to a book or video (in order to learn how to use a particular class). But I alway do refer to a book and video and subsequently feel guilty as I believe the framework reference should be enough. (I therefore feel I am not up to being a programmer) I also believe that you shouldn't need example code in order to learn how to use a particular class because Apple provides documentation for each class, but AGAIN I find my self googling example code and I find my answer like that - again I feel guilty for doing this. Am I right in saying that Apple documentation is simply not clear? and that its ok to refer to a video/book or google? or forums for that matter? I have proffesional programmers who tell me that I am worrying too much and that I should get on with it and use all the resources that I have. I just cant seem to get round this mental block that I have in my head. When I start a programming project I am able to use the excellent search skills that I have to find the code I need, copy and paste it (yes I do understand it) BUT then I feel guilty telling myself that why didn't you think up the code yourself???? Therefore your not a real programmer, your just good at googling. Currently I am going through 20+ books so that I can learn most of the frameworks, syntax etc to develop iphone apps. I believe if I do this, then when I think of a project I can make it quickly. Should I read a few books, like 2-3 and then just start a project /app , and if I get stuck just google it and get the code I need? Can anybody please answer my questions?

  • How can I do something when a runloop event is done processing?

    - by quixoto
    I have some processing in my Cocoa app that sometimes ends up calling through a hierarchy of data to do a bunch of work as the result of an event. Each small piece creates and destroys some resources. I don't want those resources around most of the time, but I would like to find a smart way of creating them before all the work and killing them at the end. Short of making those buffers etc available globally from the "parent" or elsewhere, is there a way to know locally in some code when an event loop run has ended? Then I could create them if they're not there, and keep them until the run loop ends, reusing them for any subsequent calls before that time. EDIT: I'm not looking for suggestions on how to restructure my code, which I may do anyways. This issue just brought up the question for me of how to know when the runloop is done. If I were writing in, I dunno, Javascript, I'd use a setTimeout with zero to accomplish end-event cleanup. I suppose an NSTimer with an interval of zero might accomplish this too, but wondering if there's something cleaner. Thanks.

  • Using MEF to build a tabbed application dynamically

    - by Mmarquee
    I'm rather taken with MEF and plan to use it to build a demo application to load different tabs. I am a begineer at MEF and WPF and although MEF is loading the assemblies I'm stuck at loading the controls into the TabItem I have created. My code looks a bt like this .. foreach (var page in pages) { TabItem item = new TabItem(); item.Header = page.PageTitle; /// Errm??? // Add each page tcPageControl.Items.Add(item); } The tabs are Pages, so I might be doing it totally wrong, and any help would be appreciated. Thanks in advance

  • jQuery: How to collect values from sliders into simple object with id as keys

    - by Svish
    I have several jQuery UI Sliders and I want to collect their values. Thought it would be a simple task, but when I was going to do it I got stuck and not quite sure what to do anymore :p The object I would like to end up with should look something like this: { a: 80, b: 90, c: 20, ... } I can do it manually like this: var values = { a: $('#a').slider('value'), b: $('#b').slider('value'), c: $('#c').slider('value'), ... }; But that's a bit tedious, especially if I need to add or remove or rename. Was hoping I could do something with the map or each function or something like that, but I can't figure it out. Anyone have some clever ideas?

  • Rails / omitted from link_to?

    - by dannymcc
    Hi Everyone, I am using a Gem to communicate with FreeagentCentral via their API. I have the following code to display a link to the relevant freeagent project: <%= link_to "#{image_tag('/images/icons/Spinning Beach Ball.png')} Freeagent Project", "#{Freeagent::Base.site.to_s + Freeagent::Project.element_path(@kase.freeagent_id).gsub(/\A\//, '').gsub!(/.xml/,'')}" if @kase.freeagent_id %> The problem - There is a / omitted from the URL which makes the url like this: https://XXXXX.freeagentcentral.comprojects/12345 where it should be: https://XXXXX.freeagentcentral.com/projects/12345 This may be simple, but to me - it's driving me crazy! Thanks, Danny

  • What some good PHP jobs?

    - by ggfan
    I am no professional PHP coder or anything, in fact I am fairly new. I can develop sites but nothing too crazy or fancy with PHP,Mysql,CSS,HTML,javascript. Up to now, all I have been doing is practice coding from books and websites. I am now looking for a 'real-life' experience. Besides going to a company and getting an interview, are there any other options in which I can get paid to code? I have posted some ads on craiglists but that's about it. And because this is my first time going to the 'real-word' and can make mistakes, am I liable if...a site I made for someone gets hacked and that person losses information?
