  • Override absolute position on child container (modal window)

    - by Shawn Mclean
    I have a modal window that is pulled from the server and inserted into a container that is absolute positioned. When that window is triggered to open, it does not display properly, it positions itself inside the container and most of it is hidden. Is there a specific css to be written for the container of the modal window (MyModalWindow). My code is as follows: <div style="position:relative;"> <div style="position: absolute;"> <div id="MyModalWindow"> </div> </div> </div> This is a jquery tools window and attaches the following style to MyModalWindow when it shows.: element.style { display:block; left:183.5px position:absolute; top:468.4px; z-index:9999; } I basically need the div to not be a child of the parent, since as jquery calculates it to be positioned at the center of the webpage no matter where the div is.

  • Strange(?) Opera Floating

    - by SkaveRat
    I have some strange floating behaviour on opera (IE f's up completely different, but that's for later). I'm floating the i-icons to the right. It works nicely on Fx and WebKit, but opera shifts the icons down a bit. Anyone got an idea how this happenes? CSS: .dataRow { margin: 5px 0; clear:right; } .dataRow label{ display: block; float:left; width: 160px; vertical-align: middle; font-size: 80%; } .dataGroup a img { border:0;float:right; position:relative; right:0; } .dataGroup a:hover { background:#EBEDC7; text-decoration:none; } .dataGroup a.tooltip span { display:none; padding:2px 3px; margin-top:20px; width:100px; font-size: 80%; } .dataGroup a.tooltip:hover span { display:inline; position:absolute; border:1px solid #632D11; background:#C2BD6C; color:#fff; } HTML: <fieldset class="dataGroup"> <div class="dataRow"><label>Foobar:</label> <input name="foobar" size="10" value="somedata" /> <a href="#" class="tooltip"><img src="/img/admin/information.png"/><span>Tooltip Info</span></a></div> </fieldset>

  • VS2010 Web Deploy: how to remove absolute paths and automate setAcl?

    - by Julien Lebosquain
    The integrated Web Deployment in Visual Studio 2010 is pretty nice. It can create a package ready to be deployed using MSDeploy on a target IIS machine. Problem is, this package will be redistributed to a client that will install it himself using the "Import Application" from IIS when MSDeploy is installed. The default package created always include the full path from the development machine, "D:\Dev\XXX\obj\Debug\Package\PackageTmp" in the source manifest file. It doesn't prevent installation of course since it was designed this way, but it looks ugly in the import dialog and has no meaning to the client. Worse he will wonder what are those paths and it looks quite confusing. By customizing the .csproj file (by adding MSBuild properties used by the package creation task), I managed to add additional parameters to the package. However, I spent most of the afternoon in the 2600 lines long Web.Publishing.targets trying to understand what parameter influenced the "development path" behavior, in vain. I also tried to use the setAcl to customize security on a given folder after deployment, but I only managed to do this with MSBuild by using a relative path... it shouldn't matter if I resolve the first problem though. I could modify the generated archive after its creation but I would prefer if everything was automatized using MSBuild. Does anyone know how to do that?

  • boost::filesystem - how to create a boost path from a windows path string on posix plattforms?

    - by VolkA
    I'm reading path names from a database which are stored as relative paths in Windows format, and try to create a boost::filesystem::path from them on a Unix system. What happens is that the constructor call interprets the whole string as the filename. I need the path to be converted to a correct Posix path as it will be used locally. I didn't find any conversion functions in the boost::filesystem reference, nor through google. Am I just blind, is there an obvious solution? If not, how would you do this? Example: std::string win_path("foo\\bar\\asdf.xml"); std::string posix_path("foo/bar/asdf.xml"); // loops just once, as part is the whole win_path interpreted as a filename boost::filesystem::path boost_path(win_path); BOOST_FOREACH(boost::filesystem::path part, boost_path) { std::cout << part << std::endl; } // prints each path component separately boost::filesystem::path boost_path_posix(posix_path); BOOST_FOREACH(boost::filesystem::path part, boost_path_posix) { std::cout << part << std::endl; }

  • LINQ to Entities question about orderby and null collections.

    - by Chevex
    I am currently developing a forum. I am new to LINQ and EF. In my forum I have a display that shows a list of topics with the most recent topics first. The problem is that "most recent" is relative to the topic's replies. So I don't want to order the list by the topic's posted date, rather I want to order the list by the topic's last reply's posted date. So that topics with newer replies pop back to the top of the list. This is rather simple if I knew that every topic had at least one reply; I would just do this: var topicsQuery = from x in board.Topics orderby x.Replies.Last().PostedDate descending select x; However, in many cases the topic has no replies. In which case I would like to use the topic's posted date instead. Is there a way within my linq query to order by x.PostedDate in the event that the topic has no replies? I'm getting confused by this and any help would be appreciated. With the above query, it breaks on topics with no replies because of the x.Replies.Last() which assumes there are replies. LastOrDefault() doesn't work because I need to access the PostedDate property which also assumes a reply exists. Thanks in advance for any insight.

  • IE6 transparency+radio button can't be clicked

    - by Jonas Byström
    IE6: when I place a partially transparent image in a div, the radio buttons in that div that overlap the non-transparent pixels of the image become unclickable. Example: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <style media="screen" type="text/css"> div { position: relative; width: 500px; height: 300px; _filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=http://upload.wikimedia.org/wikipedia/commons/thumb/f/fc/Olympic_flag_transparent.svg/200px-Olympic_flag_transparent.svg.png, sizingMethod='crop'); } input { position: absolute; top: 40px; left: 60px; } </style> </head> <body> <div> <input type="radio" value="1" name="1"/> </div> </body> </html> If you test the code, you can also try moving the button from (60, 40) to (40, 40) where the image is transparent, and voilà - the clicking is back in business again. This bug might, or might not, be related to the IE6 links transparency bug, but I'm not knowledgable enough to grasp any resemblence. Have I done something wrong? Or how can I circumvent? Is there some other option apart from removing the _filter:progid?

  • JSmooth question on bundling a JRE

    - by chama
    I'm trying to bundle a JRE with my jar file so that I can run my application on any windows computer, regardless of if it has Java or not. The jsmooth manual says: For the option to work correctly, you have to put a JRE in a directory near the EXE (generally in a subdirectory called "jre" or whatever). Once the exe is generated, it will FIRST try to locate the JRE at the location mentioned. If it can't be found there, then it will fallback in the normal jre look-up mode (search for a jre or a jdk in the Windows registry or in commonly-used environment variables). There is no JVM-version check when using a bundled JRE, as the packager is supposed to bundle a suitable JVM for the application. Does this mean that the jre subfolder should be included in the jar, be its own separate jar, or put in the folder that comes along with the exe? If it is supposed to be in a folder with the exe, how can I specify the relative path to the jre subfolder? My directories are as follows: setup/ -jre/ -myprogram.exe I tried using ..\jre, .\jre, ..\setup\jre in the GUI screen, but none of them worked. Any ideas or leads would be greatly appreciated. Thanks so much! EDIT: when I tried jre (and ..\jre I think), I got the following error message from windows when I tried running it "MyProgram.exe has stopped running." When I look at the problem details, it says APPCRASH and the fault module name is jvm.dll

  • Conditional column values in NSTableView?

    - by velocityb0y
    I have an NSTableView that binds via an NSArrayController to an NSMutableArray. What's in the array are derived classes; the first few columns of the table are bound to properties that exist on the base class. That all works fine. Where I'm running into problem is a column that should only be populated if the row maps to one specific subclass. The property that column is meant to display only exists in that subclass, since it makes no sense in terms of the base class. The user will know, from the first two columns, why the third column's cell is populated/editable or not. The binding on the third column's value is on arrangedObjects, with a model path of something like "foo.name" where foo is the property on the subclass. However, this doesn't work, as the other subclasses in the hierarchy are not key-value compliant for foo. It seems like my only choice is to have foo be a property on the base class so everybody responds to it, but this clutters up the interfaces of the model objects. Has anyone come up with a clean design for this situation? It can't be uncommon (I'm a relative newcomer to Cocoa and I'm just learning the ins and outs of bindings.)

  • Help with use of .NET Generics/Dictionary in replacing my Arrays

    - by Rollo R
    Hello, I have these code: Mypage.cs string[] strParameterName = new string[2] {"?FirstName", "?LastName"}; string[] strParameterValue = new string[2] {"Josef", "Stalin"}; MyConnection.MySqlLink(strConnection, strCommand, strParameterName, strParameterValue, dtTable); Myclass.cs public static void MySqlLink(string strConnection, string strCommand, string[] strParameterName, string[] strParameterValue, DataTable dtTable) { dtTable.Clear(); MySqlConnection MyConnection = new MySqlConnection(strConnection); MySqlCommand MyCommand = new MySqlCommand(strCommand, MyConnection); for (int i = 0; i < strParameterName.Length; i++) { MyCommand.Parameters.AddWithValue(strParameterName[i].ToString(), strParameterValue[i].ToString()); } MySqlDataAdapter MyDataAdapter = new MySqlDataAdapter(MyCommand); MyDataAdapter.Fill(dtTable); } And then my Sql Command will be something like "SELECT * FROM MyTable WHERE FirstName=?FirstName AND LastName=?LastName" As you can see, I am using arrays for the Parameter Name and Parameter Value and they both have to "match" with each other and ofcourse the Sql Command. Someone recommended to me that I use .NET "Dictionary" instead of arrays. Now I have never used that before. Can someone show me a relative example of how I am to use .NET Dictionary here?

  • How to force positioned elements to stay withing viewable browser area?

    - by jessegavin
    I have a script which inserts "popup" elements into the DOM. It sets their top and left css properties relative to mouse coordinates on a click event. It works great except that the height of these "popup" elements are variable and some of them extend beyond the viewable area of the browser window. I would like to avoid this. Here's what I have so far <script type="text/javascript"> $(function () { $("area").click(function (e) { e.preventDefault(); var offset = $(this).offset(); var relativeX = e.pageX - offset.left; var relativeY = e.pageY - offset.top; // 'responseText' is the "popup" HTML fragment $.get($(this).attr("href"), function (responseText) { $(responseText).css({ top: relativeY, left: relativeX }).appendTo("#territories"); // Need to be able to determine // viewable area width and height // so that I can check if the "popup" // extends beyond. $(".popup .close").click(function () { $(this).closest(".popup").remove(); }); }); }); }); </script>

  • How should I configure grub for booting linux kernel from a USB hard drive?

    - by skolima
    I have a laptop hard drive in an external enclosure which I use as a large pendrive. For an added twist, I have installed Linux on it, so I can boot any machine with my distribution of choice (e.g. for data recovery or repairing a b0rked system or just using a borrowed laptop without destroying the preinstalled Windows). The problem is that, depending on the hardware configuration, the USB hard drive may be visible under different paths. For grub configuration I just use (hda0,0) as it is relative to the device the grub was launched from. I have UUID entries in /etc/fstab. I also specify rootwait in the kernel parameters so that it waits for the USB subsystem to settle down before trying to mount the device. What should I pass to the kernel as root= ? Currently boot from the pendrive once, check the debug messages to see what /dev/sdX device has been assigned to the USB drive by the kernel, then reboot and edit the grub configuration. I can't change anything on the PC besides enabling Boot from USB hard drive in BIOS and setting it to higher priority than internal hard drives. There are various initrd generating scripts which include support for UUID in root device path, unfortunately the Gentoo native one (genkernel) does not support rootwait and I had no luck trying to use others. The boot process goes like this (it is quite similar in Windows): The BIOS chooses the boot device and loads whatever is its MBR (which happens to be grub stage-1). Grub loads it's configuration and stage-2 files from device it has set as root, using (hd0) for the device it was loaded from by BIOS. Grub loads and starts a kernel (still the same numbering, so I can use (hd0,0) again ). Kernel initializes all built-in devices (rootwait does it's magic now). Kernel mounts the partition it was passed as root (this is a kernel parameter, not grub parameter). init.d starts the userland booting process, including mounting things from /etc/fstab. Part 5 is the one giving me problems.

  • asp.net master page/content page interaction with style sheet

    - by Matt
    Learning how to do a master page in asp.net. Trying to figure out how my style sheet interacts with respects to the master page and content page. I can get HTML tags like body and the style sheet to react. But when I call the ID attribute of a label no styling takes place. What am I missing here as far as interaction? BTW I'm using VS2008 CSS sample: body { height:1200px; width:920px; border-style:solid; border-color:blue; padding:10px 10px 10px 10px; } #toptext1 { position:relative; top:-225px; right:-500px; font-size:22px; font-weight:bold; } From the master page: <body> <form id="form1" runat="server"> <asp:image id="cookNookLogo" ImageUrl="images/Logo.gif" runat="server" AlternateText="CookNook" Width="449px"></asp:image> <p> <asp:Label ID="toptext1" runat="server" Text="Quality Recipes, Hints and Supplies"></asp:Label> </p> From the content page: <%@ Page Language="C#" MasterPageFile="~/CNMasterPage.master" AutoEventWireup="true" CodeFile="Home.aspx.cs" Inherits="Home" Title="Untitled Page" %> <asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"> <link href="App_Themes/cn/cn.css" rel="stylesheet" type="text/css" /> </asp:Content> When I was doing this without a master page it worked so where am I going wrong with the attributes?

  • How to make ActionController::Base.asset_host and Base.relative_url_root independent?

    - by GSP
    In our Intranet environment we have a decree that common assets (stylesheets, images, etc) should be fed from Apache root while Rails apps runs from from a "sub directory" (a proxy to a Mongrel cluster). In other words: <%= stylesheet_tag '/common' %> # <link href="http://1.1.1.1/stylesheets/common.css" /> <%= link_to 'Home', :controller=>'home', :action=>'index' %> # <a href="http://1.1.1.1/myapp/" /> What I would like to do is define the assets and relative url in my configuration like this: ActionController::Base.asset_host=http://1.1.1.1 ActionController::Base.relative_url_root=/myapp But when I do this, the relative_url_root value gets appended to the asset_host value. (e.g. <link href="http://1.1.1.1/myapp/stylesheets/common.css"> ) Is there a way to stop this? And, more importantly, is there a best practice for how to deploy a rails app to an environment like this? (BTW, I don't want to simply hard code my asset paths since the development environment does not match the test and production environments.) Environment: Rails 2.3.4 Ruby 1.8.7 RedHat Linux 5.4?

  • mimic a table using css

    - by user357523
    I'm trying to display a grid of items, with each item having a photo on the left and a description on the right, something like this: ---------------------------- | photo | item description | ---------------------------- I want to display these items in a 3x3 grid on the page. I have the grid part worked out, what I'm having trouble with is alignment of the photo and description. When the height of the description exceeds the height of the photo, I don't want the text to wrap under the photo. I essentially want to maintain two separate columns. I have tried this: .item{ padding-left: 60px; // size of photo + 5px margin background-position: 5px 0px; } <div class="item" style="background-image: url('/img/photo123.jpg');"> Here is the item description </div> That has worked very well. the markup is clean and I don't have to mess around with absolute/relative, however, now I can't add a border to the image. Can anyone suggest a workaround or alternative?

  • Queries within queries: Is there a better way?

    - by mririgo
    As I build bigger, more advanced web applications, I'm finding myself writing extremely long and complex queries. I tend to write queries within queries a lot because I feel making one call to the database from PHP is better than making several and correlating the data. However, anyone who knows anything about SQL knows about JOINs. Personally, I've used a JOIN or two before, but quickly stopped when I discovered using subqueries because it felt easier and quicker for me to write and maintain. Commonly, I'll do subqueries that may contain one or more subqueries from relative tables. Consider this example: SELECT (SELECT username FROM users WHERE records.user_id = user_id) AS username, (SELECT last_name||', '||first_name FROM users WHERE records.user_id = user_id) AS name, in_timestamp, out_timestamp FROM records ORDER BY in_timestamp Rarely, I'll do subqueries after the WHERE clause. Consider this example: SELECT user_id, (SELECT name FROM organizations WHERE (SELECT organization FROM locations WHERE records.location = location_id) = organization_id) AS organization_name FROM records ORDER BY in_timestamp In these two cases, would I see any sort of improvement if I decided to rewrite the queries using a JOIN? As more of a blanket question, what are the advantages/disadvantages of using subqueries or a JOIN? Is one way more correct or accepted than the other?

  • CSS style submit like href tag

    - by seth.vargo
    Hi all, I have a button class that I wrote in CSS. It essentially displays block, adds some styles, etc. Whenever I add the class to a tags, it works fine - the a tag spans the entire width of its container like display:block should do... However, when I add the button class to an input button, Chrome, Safari, and Firefox all add a margin-right: 3px... I've used the DOM inspector in both Chrome and Safari and NO WHERE should it be adding a extra 3px padding. I tried adding margin: 0 !important; and/or margin-right: 0 !important to my button class in my CSS, but the browser STILL renders a 3px right margin! Is this a known issue, and is there a CSS-based solution (i.e. not jQuery/javascript) CODE FOLLOWS: .button { position: relative; display: block; margin: 0; border: 1px solid #369; color: #fff; font-weight: bold; padding: 11px 20px; line-height: 18px; text-align: center; text-transform: uppercase; cursor: hand; cursor: pointer; }

  • Set z-index with javascript setTimeout()

    - by user2266261
    What I'm trying to do is to have 4 expandable divs overlapping each other with transition set in css for 0.6s. Because the expanding lasts for 0.6s I'd like to have the expanded div lose it's higher z-index after it's done collapsing, otherwise it looks silly. However, it doesn't work, the z-index remains unchanged. It's probably somethings stupid, but I just can't find it. Thanks! <div class="wrapper" style="position: relative;"> <div id="one" style="position: absolute;" onmouseover=" this.style.height='250px'; this.style.zIndex='1'; " onmouseout=" this.style.height='50px'; setTimeout(function() {this.style.zIndex='0';},600); ">blahblahblahblah</div> <div id="two" style="position: absolute;" onmouseover=" this.style.height='250px'; this.style.zIndex='1'; " onmouseout=" this.style.height='50px'; setTimeout(function() {this.style.zIndex='0';},600); ">blahblahblahblah</div> </div>

  • Significance in R

    - by Gemsie
    Ok, this is quite hard to explain, but I'm at a complete loss what to do. I'm a relative newcomer to R and although I can completely admire how powerful it is, I'm not too good at actually using it.... Basically, I have some very contrived data that I need to analyse (it wasn't me who chose this, I can assure you!). I have the right and left hand lengths of lots of people, as well as some numeric data that shows their sociability. Now I would like to know if people who have significantly different lengths of hand are more or less sociable than those who have the same (leading into the research that 'symmetrical' people are more sociable and intelligent, etc. I have got as far as loading the data into R, then I have no idea where to go from there. How on Earth do I start to separate those who are close to symmetrical to those who aren't to then start to do the analysis? Ok, using Sasha's great advice, I did the cor.test and got the following: Pearson's product-moment correlation data: measurements$l.hand - measurements$r.hand and measurements$sociable t = 0.2148, df = 150, p-value = 0.8302 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: -0.1420623 0.1762437 sample estimates: cor 0.01753501 I have never used this test before, so am unsure how to intepret it...you wouldn't think I was on my fourth Scientific degree would you?! :(

  • Is memory allocation in linux non-blocking?

    - by Mark
    I am curious to know if the allocating memory using a default new operator is a non-blocking operation. e.g. struct Node { int a,b; }; ... Node foo = new Node(); If multiple threads tried to create a new Node and if one of them was suspended by the OS in the middle of allocation, would it block other threads from making progress? The reason why I ask is because I had a concurrent data structure that created new nodes. I then modified the algorithm to recycle the nodes. The throughput performance of the two algorithms was virtually identical on a 24 core machine. However, I then created an interference program that ran on all the system cores in order to create as much OS pre-emption as possible. The throughput performance of the algorithm that created new nodes decreased by a factor of 5 relative the the algorithm that recycled nodes. I'm curious to know why this would occur. Thanks. *Edit : pointing me to the code for the c++ memory allocator for linux would be helpful as well. I tried looking before posting this question, but had trouble finding it.
