  • UL+CSS for grid layout

    - by nailxx
    Hi all, I have a server-generated html like: <ul> <li><!-- few nested elements that form a block --></li> <li><!-- few nested elements that form anaother block --></li> <li><!-- etc, X times --></li> </ul> All blocks have known width 200px and unknown height. I want <li> to be arranged in table-like fashion like this: What I have for now is following css: li { display: block; width: 200px; float: left; margin: 10px; } All is fine except that columns don't get equal height. And in example above block #4 “snatch” at #1 and the result isn't what I'm trying to achieve: Is there any pure-CSS cross-browser way that will allow grid layout I want and will not enforce markup change?

  • CodeIgniter - Post multiple arrays to controller

    - by Bobe
    I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

  • jquery ui tabs redirecting to ASPX page on postbacks

    I am being redirected to the actual aspx page when I submit the form. How to avoid the redirection.

  • Doing Forms With Just Windows SharePoint Services 3.0?

    - by tekiegreg
    For the most part my organization is happy with WSS 3.0 (no upgrading to MOSS) with one exception, there is really just one form we'd like to put up somehow. It's fairly big form (basically change requests for IT services, on paper it's easily 2 full 8.5 by 11 pages). We thought about Custom ASP.NET coding as a separate stand-alone page or maybe as a web part. What have other people out there done? MOSS and Infopath is not really an option as it really is too expensive for us at this time. Thanks in advance!

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • Triple monitor setup with an ATI Radeon 4200?

    - by Ben Clapp
    I have a relatively new Powerspec computer (i5 quad core processor, about a year or two old) and just grabbed a new relatively inexpensive ($40?) graphics card. It has 1 DVI, one VGA, and one HDMI output. I have two (different type) monitors plugged into the DVI and VGA slots, and they work great. However, I cannot seem to be able to get a third monitor in the HDMI slot to work. I can see the monitor (and monitor info) show up in display settings. However, if I try to switch the monitor to 'on' and click apply, nothing happens. Anyone have the slightest idea what the problem might be? (It's a Radeon graphics card FYI; if I remember right I think it was the Radeon 4200?)

  • Hidden Features of Visual Studio winforms designer

    - by CodingBarfield
    One of the most loved and hated feautures of visual studio must be the form designer. Creating a simple form/user control layout usually is a breeze. Setting properties and adding events is easy. Setting up the toolbox to use you own controls can be a bit harder and getting the ToolBoxIcons to show up can be a pain. Using third party components by visual inheritance can throw of the designer. And using multiple inheritance on designerables can be really hard. So what are your favorite 'hidden' and or obvious visual studio designer features.

  • Which Ant property contains the CWD when the ant script is run?

    - by Chris R
    I don't want to get the basedir -- that appears to contain the build.xml script -- I want the CWD of the call to ant itself. Basically, I want to do this: $ cd /home/chrisr/projects/some_project $ ant -f ../../tools/ant-build-rules/library.xml build-library At this point, I need two things: The path to ant-build-rules in absolute form; this is currently found in the basedir property, so I'm set there. The path of some_project, in absolute form. This is what I don't know how to get. Which property contains this information?

  • Roll Your Own Passive 3D Movie System with Dual Projectors

    - by Jason Fitzpatrick
    If you’d like to enjoy 3D movies with passive polarized glasses for less than $50,000 (the average price of a passive 3D projector), this DIY setup brings the price down to a more accessible level. Courtesy of 3D movie and theater enthusiast Jahun, this guide details how you can achieve passive 3D projection using two radically less expensive projectors, cheap polarized filters, and some software. The project won’t be free-as-in-beer but with some careful shopping the bill will ring up at the thousands instead of tens-of-thousands of dollars. Hit up the link below to see how he pulled off miming a $50,000 projector for less than a tenth the cost.

  • .NET development on a Retina MacBook Pro with Windows 8

    - by Jeff
    I remember sitting in Building 5 at Microsoft with some of my coworkers, when one of them came in with a shiny new 11” MacBook Air. It was nearly two years ago, and we found it pretty odd that the OEM’s building Windows machines sucked at industrial design in a way that defied logic. While Dell and HP were in a race to the bottom building commodity crap, Apple was staying out of the low-end market completely, and focusing on better design. In the process, they managed to build machines people actually wanted, and maintain an insanely high margin in the process. I stopped buying the commodity crap and custom builds in 2006, when Apple went Intel. As a .NET guy, I was still in it for Microsoft’s stack of development tools, which I found awesome, but had back to back crappy laptops from HP and Dell. After that original 15” MacBook Pro, I also had a Mac Pro tower (that I sold after three years for $1,500!), a 27” iMac, and my favorite, a 17” MacBook Pro (the unibody style) with an SSD added from OWC. The 17” was a little much to carry around because it was heavy, but it sure was nice getting as much as eight hours of battery life, and the screen was amazing. When the rumors started about a 15” model with a “retina” screen inspired by the Air, I made up my mind I wanted one, and ordered it the day it came out. I sold my 17”, after three years, for $750 to a friend who is really enjoying it. I got the base model with the upgrade to 16 gigs of RAM. It feels solid for being so thin, and if you’ve used the third generation iPad or the newer iPhone, you’ll be just as thrilled with the screen resolution. I’m typically getting just over six hours of battery life while running a VM, but Parallels 8 allegedly makes some power improvements, so we’ll see what happens. (It was just released today.) The nice thing about VM’s are that you can run more than one at a time. Primarily I run the Windows 8 VM with four cores (the laptop is quad-core, but has 8 logical cores due to hyperthreading or whatever Intel calls it) and 8 gigs of RAM. I also have a Windows Server 2008 R2 VM I spin up when I need to test stuff in a “real” server environment, and I give it two cores and 4 gigs of RAM. The Windows 8 VM spins up in about 8 seconds. Visual Studio 2012 takes a few more seconds, but count part of that as the “ReSharper tax” as it does its startup magic. The real beauty, the thing I looked most forward to, is that beautifully crisp C# text. Consolas has never looked as good as it does at 10pt. as it does on this display. You know how it looks great at 80pt. when conference speakers demo stuff on a projector? Think that sharpness, only tiny. It’s just gorgeous. Beyond that, everything is just so responsive and fast. Builds of large projects happen in seconds, hundreds of unit tests run in seconds… you just don’t spend a lot of time waiting for stuff. It’s kind of painful to go back to my 27” iMac (which would be better if I put an SSD in it before its third birthday). Are there negatives? A few minor issues, yes. As is the case with OS X, not everything scales right. You’ll see some weirdness at times with splash screens and icons and such. Chrome’s text rendering (in Windows) is apparently not aware of how to deal with higher DPI’s, so text is fuzzy (the OS X version is super sharp, however). You’ll also have to do some fiddling with keyboard settings to use the Windows 8 keyboard shortcuts. Overall, it’s as close to a no-compromise development experience as I’ve ever had. I’m not even going to bother with Boot Camp because the VM route already exceeds my expectations. You definitely get what you pay for. If this one also lasts three years and I can turn around and sell it, it’s worth it for something I use every day.

  • AdSense CPM and content topics

    - by Silver Moon
    I run a few blogs on topics like programming, linux tips and network security. I noticed the following: Till last year had only 1 blog that had posts on PHP, linux tips, network security etc. The AdSense RPM was around 1.00. Then I split the content into 3 separate blogs, one focused on web development/PHP/MySQL. second one focused on Linux/Windows how-tos and tips and third one focused on network security and related network topics. The Adsense RPM rose significantly for 2 blogs, and was 1.38 (PHP blog), 0.87 (tech tips blog) and 1.90 (network security blog). In the month of april 2013 the site on network security had the highest traffic and the Adsense income of that site was twice that of all three sites combined previously. My question is simple, does focusing on one topic lead to higher CPC/CPM?

  • How to use the correct Google OpenID url to login to my site?

    - by Michael Mao
    Hello everyone: I am trying to implement OpenID as one preferred option to my next web app here The code is taken from this tutorial and works if I use my openID from myopenid.com However, I believe most people would just love to use their everyday email address as their openID, as far as I know, Google, Yahoo, and some other big players have already done this in their systems. My question is: how could I find the correct "url" to enter in the form to login? I used my Google OpenID account for StackOverflow and it works just fine. I try to copy my openID like this: www.google.com/accounts/o8/id?id=aitoawllano10bzdzp3ht0diffry0qt6_j2ls-m And paste it directly into my form, but it doesn't work. I also tried to remove the url parameter, but that won't do, either. Thanks a lot in advance for any tips and suggestions.

  • Windows GUI application when user is not logged in?

    - by Tiax
    I've written a Autoit script that starts a GUI application, when the application starts there is a login form. The scripts fills the login form and tries to log in. Then it records the time it took to login to the application and shuts the application down afterwards, writes a output file with the time it took. The thing is, I can't get the application to start unless Im logged in as the user the Scheduled task is running on. So my question is: Is there any way to start a GUI application even though the user isn't logged in? Or is the only way to have a user always logged in?

  • Using an actor model versus a producer-consumer model?

    - by hewhocutsdown
    I'm doing some early-stage research towards architecting a new software application. Concurrency and multithreading will likely play a significant part, so I've been reading up on the various topics. The producer-consumer model, at least how it is expressed in Java, has some surface similarities but appears to be deeply dissimilar to the actor model in use with languages such as Erlang and Scala. I'm having trouble finding any good comparative data, or specific reasons to use or avoid the one or the other. Is the actor model even possible with Java or C#, or do you have do use one of the languages built for the purpose? Is there a third way?

  • Django Distinct on queryset in forms.py

    - by Thomas
    Hi all, I try to get a list with distinct into the forms.py like this: forms.ModelMultipleChoiceField(queryset=Events.objects.values('hostname'), required=False).distinct() In the python shell this command works perfect, but when trying it in forms.py leaves me a blank form, so nothing appears. When i just do Events.objects.all() the form appears, but distinct doesn't work with Events.objects.all()... i also tried values_list etc but doesn't seem to fit into the forms neither... anyone got an idea how to get a SELECT DISTINCT into a ModelMultipleChoiceField? I read some other questions about this at stackoverflow but nothing seems to work out with me, so hopefully someone knows how to do this in forms.py. Thxs in advance

  • MemoryStream, XmlTextWriter and Warning 4 CA2202 : Microsoft.Usage

    - by rasx
    The Run Code Analysis command in Visual Studio 2010 Ultimate returns a warning when seeing a certain pattern with MemoryStream and XmlTextWriter. This is the warning: Warning 7 CA2202 : Microsoft.Usage : Object 'ms' can be disposed more than once in method 'KinteWritePages.GetXPathDocument(DbConnection)'. To avoid generating a System.ObjectDisposedException you should not call Dispose more than one time on an object.: Lines: 421 C:\Visual Studio 2010\Projects\Songhay.DataAccess.KinteWritePages\KinteWritePages.cs 421 Songhay.DataAccess.KinteWritePages This is the form: static XPathDocument GetXPathDocument(DbConnection connection) { XPathDocument xpDoc = null; var ms = new MemoryStream(); try { using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { writer.WriteStartDocument(); writer.WriteStartElement("data"); do { while(reader.Read()) { writer.WriteStartElement("item"); for(int i = 0; i < reader.FieldCount; i++) { writer.WriteRaw(String.Format("<{0}>{1}</{0}>", reader.GetName(i), reader[i].ToString())); } writer.WriteFullEndElement(); } } while(reader.NextResult()); writer.WriteFullEndElement(); writer.WriteEndDocument(); writer.Flush(); ms.Position = 0; xpDoc = new XPathDocument(ms); } } } finally { ms.Dispose(); } return xpDoc; } The same kind of warning is produced for this form: XPathDocument xpDoc = null; using(var ms = new MemoryStream()) { using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { //... } } } return xpDoc; By the way, the following form produces another warning: XPathDocument xpDoc = null; var ms = new MemoryStream(); using(XmlTextWriter writer = new XmlTextWriter(ms, Encoding.UTF8)) { using(DbDataReader reader = CommonReader.GetReader(connection, Resources.KinteRssSql)) { //... } } return xpDoc; The above produces the warning: Warning 7 CA2000 : Microsoft.Reliability : In method 'KinteWritePages.GetXPathDocument(DbConnection)', object 'ms' is not disposed along all exception paths. Call System.IDisposable.Dispose on object 'ms' before all references to it are out of scope. C:\Visual Studio 2010\Projects\Songhay.DataAccess.KinteWritePages\KinteWritePages.cs 383 Songhay.DataAccess.KinteWritePages In addition to the following, what are my options?: Supress warning CA2202. Supress warning CA2000 and hope that Microsoft is disposing of MemoryStream (because Reflector is not showing me the source code). Rewrite my legacy code to recognize the wonderful XDocument and LINQ to XML.

  • Content theft - Where can I go from here?

    - by Toby
    I am the webmaster of a very successful blog in a fairly small niche. Recently our success has started to bite us with people copying posts on the site without consent and trying to pass them off as their own work. Most sites stop as soon as you contact them but there is one in particular that is a blogger site which persists in passing off our content as their own. Every post we find we report to Google and they have been fairly good at taking the posts offline within a day or two but this isn't good enough or a long term solution. Given the nature of what is being blogged about after 24 hours the post is pretty much useless so I need some way to just stop them from taking our content? Any ideas? I don't want to go down the route of using a third party for people to get our RSS feed but I guess that is one option?

  • Disqus-like comment server

    - by wxs
    Hi all, I'm looking at setting up a blog, and I think I want to go the static website compiler route, rather than the perhaps more conventional Wordpress route. I'm looking at using blogofile, but could use jekyll as well. These tools recommend using disqus to embed a javascript comment widget on blog posts. I'd go that route, but I'd rather host the comments myself, rather than use a third party. I could certainly write my own dirt-simple comment server, but I was wondering if anyone knew of one that already exists (of the open source variety). Thanks!

  • ObjectDisposedException from core .NET code

    - by John
    I'm having this issue with a live app. (Unfortunately this is post-mortem debugging - I only have this stack trace. I've never seen this personally, nor am I able to reproduce). I get this Exception: message=Cannot access a disposed object. Object name: 'Button'. exceptionMessage=Cannot access a disposed object. Object name: 'Button'. exceptionDetails=System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Button'. at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_Handle() at System.Windows.Forms.Control.PointToScreen(Point p) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) exceptionSource=System.Windows.Forms exceptionTargetSite=Void CreateHandle() It looks like a mouse event is arriving at a form after the form has been disposed. Note there is none of my code in this stack trace. The only weird (?) thing I'm doing, is that I do tend to Dispose() Forms quite aggressively when I use them with ShowModal() (see "Aside" below). But I only do this after ShowModal() has returned (that should be safe right)? I think I read that events might be queued up in the event queue, but I can't believe this would be the problem. I mean surely the framework must be tolerant to old messages? I can well imagine that under stress messages might back-log and surely the window might go away at any time? Any ideas? If you could even suggest ways of reproducing, that might be useful. John Aside: TBH I've never quite understood whether calling Dispose() after Form.ShowDialog() is strictly necessary - the MSDN docs for ShowDialog() are to my mind a bit ambiguous.
