  • HTML Table: How to resize data cells when already specified "colspan"?

    - by Jenny
    I have tabular data to display, which has a meaning to both rows and columns. Columns are time blocks, rows are days. A particular datacell is confined to a single day, but can be in multiple time block. To show this, I am using the colspan tag. <div id = "GuideTable"> <table> <tr> <td colspan = 3> </td></tr></table> </div> Or Whatever. I'm trying to apply CSS formating to the entire table, and for changing colors, etc, things are fine, but wanting to have a consistent width is where I am running into problems. Right now, each data cell's width seems tied to the maximum width in its column (everything auto lines up). Some columns are itty bitty, others are huge. I'm trying to make columns consistently sized (even if that means every column is as big as the biggest column needs to be), but setting an individual datacells width (either via css or in the tag itself) is getting me nowhere. I'm thinking maybe the colspan tag is overriding my manual width? If that's the case, how can I change the width of a column as a whole, especially since they aren't explicitly defined? (CAN you explicitly define columns?) Examples of the CSS I'm using: #GuideTable td{ background:#ffffff; border-style: solid; border-width: 1px; width: 100px; }

  • selecting text by ignoring inner Elements of div tag javascript

    - by sugar
    <html> <body> <script language="javascript"> function getSelectionHTML() { var div = document.getElementById("myDiv").childNodes; if (document.createRange) { var textNode=div.firstChild; var rangeObj=document.createRange(); rangeObj.setStart(textNode,0); rangeObj.setEnd(textNode,10); selRange.collapse(true); var elem = document.getElementById('myDiv') elem .innerHTML = elem .innerHTML.replace(rangeObj.toString(), '<span style="background-color: lime">'+rangeObj.toString()+'</span>') } } </script> <div id="myDiv"> asdf as<b>dfas df asf asdf sdfjk dvh a sjkh jhcdjkv</b> iof scjahjkv ahsjv hdjk biud fcsvjksdhf k </div> <form name="aform"> <input type="button" value="Get selection" onclick="getSelectionHTML()"> </body> </html> Ok. Let me explain - getSelectionHTML() method is for selection of characters from 0 to 10. I am getting the values by "myDiv" id. but inner bold, italic & other tags are putting me in trouble. In simple words, I just want to make selection of first ten characters (& apply them span tag) which are in "myDiv" tag. What exactly I am missing ? Can anyone help me ?

  • Client-side user custom CSS single file for overriding multiple domains

    - by Cawas
    This is for using in Safari, though it could probably be used on Firefox as well. In Chrome you have to add a plugin anyway (which generally allow for custom CSS per domain), and Opera already allows this to be done without needing any CSS. But while it's for customizing on the client-side, it's also a pure CSS question. So I'm using no plugins here. So, again, I got a custom CSS code (easily) working for all domains. Now I want to get specify CSS code for each domain. All with just 1 CSS file that's being loaded by Safari. Over the web and googling, I've found two ways to supposedly do this, but none actually worked. They're both documented on userstyles.com: @-moz-document domain("your-domain.com") { }. This would be perfect, since I can have several tags like that and just choose which style will be loaded for which domain. It just doesn't work. @namespace is quite confusing and I've tried every variation I could think of. None worked.

  • Progressbar behaves strangely

    - by wanderameise
    I just created an application in C# that uses a thread which polls the UART for a receive event. If data is received an event is triggered in my main thread (GUI) and a progress bar is controlled via PerformStep() method (of course, I previously set the Max value accordingly). PerformStep is invoked using the following expression to handle cross threading this.Invoke((Action)delegate{progressBar2.PerformStep();}) When running this application the progressbar never hits its final value. It stops at 80%. When debugging and stopping at the line mentioned above, everything works fine using single steps. I have no idea what is going one! Start read thread on main thread: pThreadWrite = new Thread(new ThreadStart(ReadThread)); pThreadWrite.Start(); Read Thread: private void ReadThread() { while(1) { if (ReceiveEvent) { FlashProgressBar(); } } } Event that is triggered in main thread: private void FlashProgressBar() { this.Invoke((Action)delegate { progressBar2.PerformStep();}); } (It's a simplified representation of my code) It seems as if the internal progress is faster than the visual one.

  • C++ STL question related to insert iterators and sets

    - by rshepherd
    #include #include #include #include using namespace std; class MyContainer { public: string value; MyContainer& operator=(const string& s) { this->value = s; return *this; } }; int main() { list<string> strings; strings.push_back("0"); strings.push_back("1"); strings.push_back("2"); set<MyContainer> containers; copy(strings.begin(), strings.end(), inserter(containers, containers.end())); } The preceeding code does not compile. In typical STL style the error output is verbose and difficult to understand. The key part seems to be this... /usr/include/c++/4.4/bits/stl_algobase.h:313: error: no match for ‘operator=’ in ‘__result.std::insert_iterator::operator* [with _Container = std::set, std::allocator ]() = __first.std::_List_iterator::operator* [with _Tp = std::basic_string, std::allocator ]()’ ...which I interpet to mean that the assignment operator needed is not defined. I took a look at the source code for insert_iterator and noted that it has overloaded the assignment operator. The copy algorithm must uses the insert iterators overloaded assignment operator to do its work(?). I guess that because my input iterator is on a container of strings and my output iterator is on a container of MyContainers that the overloaded insert_iterator assignment operator can no longer work. This is my best guess, but I am probably wrong. So, why exactly does this not work and how can I accomplish what I am trying to do?

  • How can I change the default startup directory for cmd.exe?

    - by Nano HE
    Hi. My Procedure last day as below Click Start, Run and type Regedit.exe Navigate to the following branch: HKEY_CURRENT_USER \ Software \ Microsoft \ Command Processor In the right-pane, double-click Autorun and set the startup folder path as its data, preceded by “CD /d “. If Autorun value is missing, you need to create one, of type REG_EXPAND_SZ or REG_SZ in the above location. Example: To set the startup directory to D:\learning\perl, set the Autorun value data to CD /d D:\learning\perl Then I clicked Start, run and type cmd. It successfully. I could do perl practice more conveniently now. But today, I find when I try to build my Visual Studio 2005 solution which included some Pre-build event Command like this: perl.exe MyAppVersion.pl perl.exe AttrScan.pl It doesn't work. Show error: can't find the path. I check the environment variable setting and find the variable-path and it's value-c:\perl\bin\; still exist. Finially, I try to removed the Regedit.exe configuration "Autorun" value and test again. The issue fixed. I only changed the default startup directory for cmd.exe command. Why the pre-build event perl command was impacted? (I am using winxp and activePerl 5.8)

  • How to pass javascript/jQuery settings from page to page in rails?

    - by aronchick
    When doing javascript manipulation of what's visible, how does one pass that from page to page (ideally in Rails)? For example, let's say I have the following simple jQuery code: <% link_to "Next Page", report_path %> <div class="clickable-div" style="background-color:#FFFFFF;"></div> <script> $('.clickable-div').click(function () { var color = $(this).css("background-color", "#000000"); }); </script> If it's not clear, the code is just supposed to change the color of the div based on whether or not it has been clicked. Regardless, there's also a link on the page that allows someone to go to the reporting page. What's a way to pass the state of the div to the action call? EDIT It seems unnecessary to do it in a session - am I wrong? This is just something from one page to the next, I couldn't care less anywhere else on the site. EDIT 2 To confirm, Rails needs to have access to the action that occurred in Javascript on the previous page.

  • Strange offset space between <button> as parent container and <div> as child.

    - by Maxja
    I need to decorate a standard html button. The base element I took <button> instead of <input>, cos I decided that the element must be a parent container. And there is child element <div> in it. This <div> element will be been the core element for decoration, and should occupy the entire space of the parent element - button. <button> <div>*decoration goes here*</div> </button> And within Cascading Style Sheets it might be looks like this: css button { margin: 0; border: 0; padding: 0; width: *150*px; height: *50*px; position: relative; } div { margin: 0; border: 0; padding: 0; width: 100%; height: 100%; background: *black*; position: absolute; top: 0; left: 0; } html <button type="button"> <div>*decoration goes here*</div> </button> So, Opera(10) is doing well, webkits Chrome(6) and Safari(4) is doing also well, but Internet Explorer(8) is bad - DOM Inspector shows some strange Offset space in top and left, FireFox(3) is also bad - DOM Inspector shows that <div> get some negative value in css-property right: and bottom:. Even if this property will set to zero(0) DOM-Inspector still shows same negative value. I almost broke my brain. Help me, solve this problem, please!

    Please see the form HTML code below <form method="post" action="register"> <div class="email"> Email <input type="text" tabindex="1" id="email" value="" name="email"> </div> </div> <div class="agreement"> <div tabindex="2" class="terms_radio"> <div onclick="changeTerm(this);" class="radio" id="terms_radio_wrapper" style="background-position: left 0pt;"> <input type="radio" id="terms" value="1" name="terms"><label for="terms">I have read and understood the ZapAV</label> </div> </div> </div> <div class="form_submit"> <input type="button" tabindex="3" value="Cancel" name="cancel"> <input type="submit" tabindex="4" value="Submit" name="submit"> </div> </form> Here I syled teh agreement check box insuch a way that radio input is completly hidden and background image is applied to the wrapper div, and onclick of the wrapper div will toggle the backgroud image as well as the checked status of teh radio input. I need to set the tabindex index on the 'terms_radio' DIV, simply tabindex="2" attribute on div is not working, Is it possible to bring the dotted border on the label for the radio input up on pressing the TAB when the cursor is at email input field?

  • How do i find if an object is before or after a waypoint?

    - by BoMann Andersen
    Im working on a racing game for a school project. Using Visual studio 10 pro, and Irrlicht. Sorry for bad grammar ., and its my first question so not sure if its done right. How i want it to work is that i make waypoints at different points on the track, and then i run my waypoint check to see if a car is past its next waypoint (the next it "needs" to go past), if yes then it updates the next waypoint, else nothing. The way i hope this will work is, i make a vector from n to n+1, then find the vector that is perpendicular to the first vector at n. Then i see if the object is in front or behind that vector. I found a Gamedev.net forumpost that helped me make this function: void Engine::checkWaypoint(Vehicle* vehicle) { btVector3 vector = waypoints[vehicle->nextWaypoint]; // n btVector3 nextVector = waypoints[vehicle->nextWaypoint + 1]; // n+1 vector = nextVector - vector; // First vector btVector3 pos = btVector3(vehicle->position.X,vehicle->position.Y,vehicle->position.Z); float product = vector.dot(pos - waypoints[vehicle->nextWaypoint]); // positiv = before, negative = behind if(product < 0) vehicle->nextWaypoint += 1; } Current bugs with this is: Updates the nextwaypoint more then ones without going past a new point. When it gets to the end and resets, it stops triggering on the first waypoints. So my questions: Is this an good way to do this? Did i do it right?

  • How to proxy calls to the instance of an object

    - by mr.b
    Edit: Changed question title from "Does C# allow method overloading, PHP style (__call)?" - figured out it doesn't have much to do with actual question. Also edited question text. What I want to accomplish is to proxy calls to a an instance of an object methods, so I could log calls to any of its methods. Right now, I have code similar to this: class ProxyClass { static logger; public AnotherClass inner { get; private set; } public ProxyClass() { inner = new AnotherClass(); } } class AnotherClass { public void A() {} public void B() {} public void C() {} // ... } // meanwhile, in happyCodeLandia... ProxyClass pc = new ProxyClass(); pc.inner.A(); // need to write log message like "method A called" pc.inner.B(); // need to write log message like "method B called" // ... So, how can I proxy calls to an object instance in extensible way? Method overloading would be most obvious solution (if it was supported in PHP way). By extensible, meaning that I don't have to modify ProxyClass whenever AnotherClass changes. In my case, AnotherClass can have any number of methods, so it wouldn't be appropriate to overload or wrap all methods to add logging. I am aware that this might not be the best approach for this kind of problem, so if anyone has idea what approach to use, shoot. Thanks!

  • How do I change the application background color at run-time in a Flex 3.5 application?

    - by Adam Tuttle
    I have a Flex 3.5 application that will serve multiple purposes, and as part of the visual changes that I'd like to make to indicate which mode the application is in, I want to change its background color. Currently, the application tag looks like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:com="ventures.view.component.*" xmlns:views="ventures.view.*" layout="absolute" preinitialize="onPreInitialize()" creationComplete="onCreationComplete()" applicationComplete="onApplicationComplete()" click="onClick(event)" enabled="{(!chainController.generalLocked)}" backgroundGradientColors="[0xFFFFFF, 0xFFFFFF]" > I've tried using a binding, for both the backgroundColor and backgroundGradientColors attributes: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundColor="{app_background_color}" > —and— <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundGradientColors="{app_background_color}" > but for the former binding is not allowed, and for the latter there is a warning that: Data binding will not be able to detect assignments to "app_background_color". I also ran across this page which seems to indicate that I could do it with the setStyle() method, but the documentation seems to indicate that this method is only available for components, not the main canvas. I suppose I could wrap everything in a <mx:Canvas></mx:Canvas> specificially for this purpose, but that seems wasteful—like Div-itis in HTML or something. What's the best way to change the main application background color at run-time?

  • Spring annotation-based container configuration context:include & exclude filters

    - by lisak
    Hey, first off I point to the similar question. I spent more than an hour to set this up, but PathMatchingResourcePatternResolver still scans everything. I have one common.xml (that is imported from specific.xml) and a specific.xml bean definition file. The context is loaded from specific.xml. In common.xml there is this element: <context:component-scan base-package="cz.instance.transl"> <context:exclude-filter type="aspectj" expression="cz.instance.transl.model..* &amp;&amp; cz.instance.transl.service..* &amp;&amp; cz.instance.transl.hooks..*"/> </context:component-scan> Where classes in packages like cz.instance.transl.service.* should not be subject of scanning, but everything else in here cz.instance.transl.* should be scanned through. But PathMatchingResourcePatternResolver marks everything as matching resources. It is the same with regex. BTW: in xml style configuration, one can have many components that share a common.xml beans via "import resource" when loading context. How this is done when Annotation-based container configuration is used ?

  • Unexpected behaviour of Process.MainWindowHandle

    - by Ed Guiness
    I've been trying to understand Process.MainWindowHandle. According to MSDN; "The main window is the window that is created when the process is started. After initialization, other windows may be opened, including the Modal and TopLevel windows, but the first window associated with the process remains the main window." (Emphasis added) But while debugging I noticed that MainWindowHandle seemed to change value... which I wasn't expecting, especially after consulting the documentation above. To confirm the behaviour I created a standalone WinForms app with a timer to check the MainWindowHandle of the "DEVENV" (Visual Studio) process every 100ms. Here's the interesting part of this test app... IntPtr oldHWnd = IntPtr.Zero; void GetMainwindowHandle() { Process[] processes = Process.GetProcessesByName("DEVENV"); if (processes.Length!=1) return; IntPtr newHWnd = processes[0].MainWindowHandle; if (newHWnd != oldHWnd) { oldHWnd = newHWnd; textBox1.AppendText(processes[0].MainWindowHandle.ToString("X")+"\r\n"); } } private void timer1Tick(object sender, EventArgs e) { GetMainwindowHandle(); } You can see the value of MainWindowHandle changing when you (for example) click on a drop-down menu inside VS. Perhaps I've misunderstood the documentation. Can anyone shed light?

  • method for creating PHP templates (ie html with variables)?

    - by Haroldo
    I'm designing my html emails, these are to be a block of html containing variables that i can store in a $template variable. My problem comes with the storing in the variable part. putting all my html into php makes it a pain in the bum to work with. for example, the below code is fine for a simple email but once i start getting nested tables etc its going to get really confusing... $template.= 'Welcome ' . $username . '<br /><br /><br />'; $template.= 'Thank-you for creating an account <br /><br />'; $template.= 'Please confirm your account by click the link below! <br /><br />'; $template.= '<a href="' . $sitepath . '?email=' . $email . '&conf_key=' . $key . '" style="color: #03110A;"><font size="5" font-family="Verdana, Geneva, sans-serif" color="#03110A">' . $key . '</font></a>'; $template.='</body></html>'; is there a way i can still store the html in a $var but not have to write it like this?

  • JavaScript: Changing src-attribute of a embed-tag

    - by Mike
    I have the following scenario. I show the user some audio files from the server. The user clicks on one, then onFileSelected is eventually executed with both the selected folder and file. What the function does is change the source from the embedded object. So in a way, it is a preview of the selected file before accepting it and save the user's choice. A visual aid. HTML <embed src="/resources/audio/_webbook_0001/embed_test.mp3" type="audio/mpeg" id="audio_file"> JavaScript function onFileSelected(file, directory) { jQuery('embed#audio_file').attr('src', '/resources/audio/'+directory+'/'+file); }; Now, this works fine in Firefox, but Safari and Chrome simply refuse to change the source, regardless of Operating System. jQuery finds the object (jQuery.size() returns 1), it executes the code, but no change in the HTML Code. Why does Safari prevent me from changing the <embed> source and how can I circumvent this?

  • TDD approach for complex function

    - by jamie
    I have a method in a class for which they are a few different outcomes (based upon event responses etc). But this is a single atomic function which is to used by other applications. I have broken down the main blocks of the functionality that comprise this function into different functions and successfully taken a Test Driven Development approach to the functionality of each of these elements. These elements however aren't exposed for other applications would use. And so my question is how can/should i easily approach a TDD style solution to verifying that the single method that should be called does function correctly without a lot of duplication in testing or lots of setup required for each test? I have considered / looked at moving the blocks of functionality into a different class and use Mocking to simulate the responses of the functions used but it doesn't feel right and the individual methods need to write to variables within the main class (it felt really heath robinson). The code roughly looks like this (i have removed a lot of parameters to make things clearer along with a fair bit of irrelevant code). public void MethodToTest(string parameter) { IResponse x = null; if (function1(parameter)) { if (!function2(parameter,out x)) { function3(parameter, out x); } } // ... // more bits of code here // ... if (x != null) { x.Success(); } }

  • Bootstrap inline button dropdown within <p> jumbotron

    - by C.B.
    Currently I have a jumbotron setup with some paragraph text, and I would like to stick a button dropdown inline with the text. Dropdown button <span class="btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown"> Button... <span class="caret"></span> </button> <ul class="dropdown-menu" role="menu"> <li><a href="#">Opt 1</a></li> <li><a href="#">Opt 2</a></li> </ul> </span> Jumbotron <div class="jumbotron"> <h1>Hello!</h1> <p>Welcome</p> <p>Another paragraph <!-- dropdown is here --> </p> </div> <!-- jumbotron --> If the dropdown is within the <p> tag, it does not "dropdown" (but renders). If it is outside of the <p> tag it functions fine, but I would like it to be inline with the text and need the text to be in the <p> tag to get the style. Any ideas? Things to note -- If I replace the <span> tags with <div> tags, it will work fine within the <p> tags, but won't be inline.

  • (HTML) PNG on top of another PNG - possible to eliminate full transparency?

    - by MHTri
    I'd like to put a logo png onto of another coloured png. They both have transparent backgrounds. When I try this the images blend together. Curiously, in Photoshop the logo retains its opaque-ness - I put colours on the layers underneath it, another image, etc etc, the logo is still opaque. I'd like to do it this way so I can rotate the background images. How do I fix this? [edit]I've cooked up an example image: http://i.imgur.com/XtoGn.png The left is what I want to happen, the right is what happens on all browsers (I know the background isn't transparent but bear with me - they're both transparent pngs, with the background having a gradient layer mask). I've put the images like this <div> <img id="backgroundImg" style="position: absolute; top: 0;" src="/Images/background.png" /> <img id="logoImg" src="/Images/logo.png" /> </div> I'm not entirely sure what blending mode I'm using in PS.

  • ASP.Net MVC and Windows 7 404 error

    - by Paul Rivers
    O.K. Stupid question..... I sepnt nearly a day getting an MVC site working, and then I published it. After that, the hell began. I'm using Windows 7, Visual Studio 2008 and MVC. I published it and first the Default.aspx wouldn't come up. I gave up on playing with that for a few and just did the easy thing a typed in default.aspx. I'll fix that problem later. So, I clicked on one of my navigation buttons which prior to this worked just fine in the internal development IIS, and I get a 404 error. I spent two days surfing the Microsoft support forums and every other support forum I can find. No fix. So, I tried something a little different. Just to see if I screwed up. I created a new TestMVC application. Set the output to a website on the local IIS. Compiled and after typing in the default.aspx (it was set as the startup file in the project) I then clicked on the About button on the base MVC application. And what do I get? 404. I know this is new, folks, but this is crazy. What is it about this process that would take this much effort to get it right, especially since it works on the test server.

  • Rails RESTful routs without #new, rspec trouble

    - by pdkl95
    I'm currently writing a Rails app, and hit a somewhat strange quirk. I have a controller PermissionsController, which is mainly for display purposes at the moment. So my routing is locked down: map.resources :permissions, :only => [:index, :show] Unfortunately, when writing the tests, one of the routing tests fails: it "does not recognize #new" do { :get => "/permissions/new" }.should_not be_routable end with the error: Expected 'GET /permissions/new' to fail, but it routed to {"action"=>"show", "id"=>"new", "controller"=>"permissions"} instead Obviously, the #show action's route is matching with /permissions/:id, which also gives the expected error Couldn't find Permission with ID=new if you actually browse to that URL. This is not a serious error, as it is correctly raising an exception with the bad :id parameter, but it's kind of ugly. Is there any way to actually make Rails reject that route? Some trick in the routing options that I'm missing? I suppose I should just leave that test out and ignore it, or maybe remove the whole RESTful idea altogether and go back to a simpler map.connect 'permissions/:id' style. I strongly suspect I'll be expanding this in the future, though, and kind of wanted to keep my controllers consistent with each other. Just having to add occasional :only or :except rules made routes.rb nice and clean...

  • WPF Binding Path=/ not working?

    - by Mark
    I've set up my DataContext like this: <Window.DataContext> <c:DownloadManager /> </Window.DataContext> Where DownloadManager is Enumerable<DownloadItem>. Then I set my DataGrid like this: <DataGrid Name="dataGrid1" ItemsSource="{Binding Path=/}" ... So that it should list all the DownloadItems, right? So I should be able to set my columns like: <DataGridTextColumn Binding="{Binding Path=Uri, Mode=OneWay}" Where Uri is a property of the DownloadItem. But it doesn't seem to like this. In the visual property editor, it doesn't recognize Uri is a valid property, so I'm guessing I'm doing something wrong. It was working before, when I had the data grid binding to Values, but then I took that enumerable out of the DownloadManager and made itself enumerable. How do I fix this? PS: By "doesn't work" I mean it doesn't list any items. I've added some to the constructor of the DM, so it shouldn't be empty.

    I am writing an app where I want the customer to be able to upload to Amazon S3 straight from the browser. I can make this work just fine. But when errors occur, I want to handle them more gracefully than splattering an XML document on the customer's screen. I have a scheme that I think would work, but it's failing. Here's what I'm trying: Create a form to do the upload, and store the form on S3 itself, in the same domain as the "action" attribute of the form. Redirect the customer to this form. Now their browser is sitting on https://<bucket>.s3.amazonaws.com/something. The page contains a hidden iframe. The form sets its target to the iframe. The load event handler looks at the contents of the iframe, and acts upon it. So, something like this: <iframe id="foo" name="foo" style="display: none" /> <form target="foo" action="https://<bucket>.s3.amazonaws.com/"> <input type="hidden" name="..." value="..." /> <input type="file" name="file" /> </form> with this javascript (using jquery): function handler() { var message = $("#foo").contents().find('message').text(); alert(message); } $("#foo").load(handler); Using firebug, I can see that the iframe contains an XML document, that contains a "message" node. However, the .find('message') always fails to find anything within the XML document. Notice that the action of the form has the same domain, port, and scheme as the document itself. So, I don't think that I should be running afoul of the same-origin policy. Right? But it fails every time. This is using Firefox and Google Chrome browsers. Thanks for any advice!
