• Silverlight 3: ListBox DataTemplate HorizontalAlignment

  - by Lee

  I have a ListBox with it's ItemTemplate bound to a DataTemplate. My problem is I cannot get the elements in the template to stretch to the full width of the ListBox. <ListBox x:Name="listPeople" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="0,0,0,0" Background="{x:Null}" SelectionMode="Extended" Grid.Row="1" ItemTemplate="{StaticResource PersonViewModel.BrowserDataTemplate}" ItemsSource="{Binding Mode=OneWay, Path=SearchResults}" > </ListBox> <DataTemplate x:Key="PersonViewModel.BrowserDataTemplate"> <ListBoxItem HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,5,5,5"> <Border Opacity=".1" x:Name="itemBorder" Background="#FF000000" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" CornerRadius="5,5,5,5" MinWidth="100" Height="50"/> </Grid> </ListBoxItem> </DataTemplate> As you can see, I have added a border within the grid to indicate the width of the template. My goal is to see this border expand to the full width of the listbox. Currently its width is determined by its contents or MinWidth, which is the only thing at the moment keeping it visible at all.

• How to repeatedly show a Dialog with PyGTK / Gtkbuilder?

  - by Julian

  I have created a PyGTK application that shows a Dialog when the user presses a button. The dialog is loaded in my __init__ method with: builder = gtk.Builder() builder.add_from_file("filename") builder.connect_signals(self) self.myDialog = builder.get_object("dialog_name") In the event handler, the dialog is shown with the command self.myDialog.run(), but this only works once, because after run() the dialog is automatically destroyed. If I click the button a second time, the application crashes. I read that there is a way to use show() instead of run() where the dialog is not destroyed, but I feel like this is not the right way for me because I would like the dialog to behave modally and to return control to the code only after the user has closed it. Is there a simple way to repeatedly show a dialog using the run() method using gtkbuilder? I tried reloading the whole dialog using the gtkbuilder, but that did not really seem to work, the dialog was missing all child elements (and I would prefer to have to use the builder only once, at the beginning of the program). [SOLUTION] As pointed out by the answer below, using hide() does the trick. But one has to take care that the dialog is in fact destroyed if one does not catch its "delete-event". A simple example that works is: import pygtk import gtk class DialogTest: def rundialog(self, widget, data=None): self.dia.show_all() result = self.dia.run() def destroy(self, widget, data=None): gtk.main_quit() def closedialog(self, widget, data=None): self.dia.hide() return True def __init__(self): self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.window.connect("destroy", self.destroy) self.dia = gtk.Dialog('TEST DIALOG', self.window, gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT) self.dia.vbox.pack_start(gtk.Label('This is just a Test')) self.dia.connect("delete-event", self.closedialog) self.button = gtk.Button("Run Dialog") self.button.connect("clicked", self.rundialog, None) self.window.add(self.button) self.button.show() self.window.show() if __name__ == "__main__": testApp = DialogTest() gtk.main()

• Should I choose <button> element or css buttons?

  - by Kenny Bones

  Ok, here's the thing. I've done a webpage which contains forms and so I added buttons as elements and this works great. I created their own css classes and use graphics as background images for each of them. All working great (these are submit buttons btw) Anyway, I've also got a jQuery script from before that takes all a href hyperlinks and add content from a set div from an external file and adds to a div in my current page, all in one animation. But this would probably not work with form buttons? In any case I need to be able to have these buttons work as traditional hyperlinks anyway. So what do I do? I thought about using css-buttons alltogether, but I'm not able to have them stack vertically. Using float left or right just put the buttons outside of their parent containers (probably a different fix for that). But in any case, using css buttons, that wouldn't work as a submit button for the forms anyway would it? Should I perhaps use both form buttons and css buttons? What do you do?

• javascript: waiting for an iframe page to load before writing to it (but not from the page that's tr

  - by Bill Dawes

  Apologies if this has been answered elsewhere, but I haven't been able to find it referenced. (Probably because nobody else would want to do such a daft thing, I admit). So, I have a page with three iframes in it. An event on one triggers a javascript function which loads new pages into the other two iframes; ['topright'] and ['bottomright']. However, javascript in the page that is being loaded into iframe 'topright' then needs to send information to elements in the 'bottomright' iframe. window.frames['bottomright'].document.subform.ID_client = client; etc But this will only work if the page has fully loaded into the bottomright frame. So what would be the most efficient way for that code in the 'topright' iframe to check and ensure that that form element in the bottomright frame is actually available to write to, before it does write to it? Bearing in mind that the page load has NOT been triggered from the topright frame, so I can't simply use an onLoad function. (I know this probably sounds like a hideously tortuous route for getting data from one page to another, but that's another story. The client is always right, etc...:-))

• How to read data from file(.dat) in append mode

  - by govardhan

  We have an application which requires us to read data from a file (.dat) dynamically using deserialization. We are actually getting first object and it throws null pointer exception and "java.io.StreamCorruptedException:invalid type code:AC" when we are accessing other objects using a "for" loop. File file=null; FileOutputStream fos=null; BufferedOutputStream bos=null; ObjectOutputStream oos=null; try{ file=new File("account4.dat"); fos=new FileOutputStream(file,true); bos=new BufferedOutputStream(fos); oos=new ObjectOutputStream(bos); oos.writeObject(m); System.out.println("object serialized"); amlist=new MemberAccountList(); oos.close(); } catch(Exception ex){ ex.printStackTrace(); } Reading objects: try{ MemberAccount m1; file=new File("account4.dat");//add your code here fis=new FileInputStream(file); bis=new BufferedInputStream(fis); ois=new ObjectInputStream(bis); System.out.println(ois.readObject()); **while(ois.readObject()!=null){ m1=(MemberAccount)ois.readObject(); System.out.println(m1.toString()); }/*mList.addElement(m1);** // Here we have the issue throwing null pointer exception Enumeration elist=mList.elements(); while(elist.hasMoreElements()){ obj=elist.nextElement(); System.out.println(obj.toString()); }*/ } catch(ClassNotFoundException e){ } catch(EOFException e){ System.out.println("end"); } catch(Exception ex){ ex.printStackTrace(); }

• Horizontally-centering an absolute position to match a relative position

  - by Chris Vandevelde

  I'm trying to make a div box, containing various elements, fixed at the top of the page once the page has been scrolled so that the box would normally be out of view, but scroll normally until that point (like the behaviour at http://perldoc.perl.org/perl.html). The conditionally-fixed part is pretty simple to implement (set the position to "fixed" once the user has scrolled past a certain point, and "static" once it's scrolled back up), but I'm having trouble with the positioning and dimensions; it screws up if I'm not specifying an absolute position (if I'm using % or "auto", rather than px, em, cm, etc.) or it, confusingly, left-aligns if the box is less than the width of the page. I can understand why, more or less, I'm just trying to fix it. My strategy right now is to have an invisible DIV hold the place of the box and use Prototype's clonePosition() function to hold its position, but it doesn't seem to work for some reason. Neither does copying the margin from one element to the other. Any ideas? Bonus points and eternal gratitude if you can come up with an idea that will adjust itself with the browser window (like auto margins) without setting an onresize event.

• Submit form with POST data in Android app

  - by datguywhowanders

  I've been searching the web for a way to do this for about a week now, and I just can't seem to figure it out. I'm trying to implement an app that my college can use to allow users to log in to various services on the campus with ease. The way it works currently is they go to an online portal, select which service they want, fill in their user name and pwd, and click login. The form data is sent via post (it includes several hidden values as well as just the user name and pwd) to the corresponding login script which then signs them in and loads the service. I've been trying to come at the problem in two ways. I first tried a WebView, but it doesn't seem to want to support all of the html that normally makes this form work. I get all of the elements I need, fields for user and pwd as well as a login button, but clicking the button doesn't do anything. I wondered if I needed to add an onclick handler for it, but I can't see how as the button is implemented in the html of the webview not using a separate android element. The other possibility was using the xml widgets to create the form in a nice relative layout, which seems to load faster and looks better on the android screen. I used EditText fields for the input, a spinner widget for the service select, and the button widget for the login. I know how to make the onclick and item select handlers for the button and spinner, respectively, but I can't figure out how to send that data via POST in an intent that would then launch a browser. I can do an intent with the action url, but can't get the POST data to feed into it. Anyone have any suggestions?

• How to modify a xml file using PHP? use a node to retrieve the value of new child nodes and add them

  - by Avinash Sonee

  I have pasted the example of what I need here : http://pastie.org/1005178 I have a xml file with say the following info <state> <info> <name>hello</name> <zip>51678</zip> </info> <info> <name>world</name> <zip>54678</zip> </info> </state> Now I need to create a new xml file which has the following <state> <info> <name>hello</name> <zip>51678</zip> <lat>17.89</lat> <lon>78.90</lon> </info> <info> <name>world</name> <zip>54678</zip> <lat>16.89</lat> <lon>83.45</lon> </info> </state> So, basically I need to add lat and lon nodes to each info element. these lat and lon correspond to the zip code which are stored in a mysql file which contains 3 fields - pin, lat and lon How do i do this recursively. I have say 1000 info elements in a file Please give me a sample code because I have already tried using simplexml and read the documentation but doesn't see to understand it properly

• Javascript getElementsByTagName broken firefox?

  - by Sheldon Ross

  I'm getting the weirdest issues with Javascript in Firefox today. I'm trying to manipulate some table rows, but .getElementsByTagName("tr"); is pulling back junk. dynamicTable.tableBody = dynamicTable.getElementsByTagName("tbody")[0]; var tableRows = dynamicTable.tableBody.getElementsByTagName("TR"); var actualTableRows = new Array(); for(var i in tableRows) { var row = tableRows[i]; alert(row.tagName); if(row.tagName == "TR"){ actualTableRows.push(row); } } dynamicTable.bodyRows = actualTableRows; The puzzling part of course is my temporary hack to fix the error. For some reason .getElementsByTagName("tr") is pulling back some functions also. Incidently the alert above goes something like this TR TR TR TR undefined undefined undefined. The code I wanted was something like this dynamicTable.bodyRows = dynamicTable.tableBody.getElementsByTagName("tr"); But then bodyrows does not contain just tr elements it has the aforementioned junk in it. Any thoughts?

• R: manipulating data.frames containing strings and booleans.

  - by Mike Dewar

  Hello. I have a data.frame in R; it's called p. Each element in the data.frame is either True or False. My variable p has, say, m rows and n columns. For every row there is strictly only one TRUE element. It also has column names, which are strings. What I would like to do is the following: For every row in p I see a TRUE I would like to replace with the name of the corresponding column I would then like to collapse the data.frame, which now contains FALSEs and column names, to a single vector, which will have m elements. I would like to do this in an R-thonic manner, so as to continue my enlightenment in R and contribute to a world without for-loops. I can do step 1 using the following for loop: for (i in seq(length(colnames(p)))) { p[p[,i]==TRUE,i]=colnames(p)[i] } but theres's no beauty here and I have totally subscribed to this for-loops-in-R-are-probably-wrong mentality. Maybe wrong is too strong but they're certainly not great. I don't really know how to do step 2. I kind of hoped that the sum of a string and FALSE would return the string but it doesn't. I kind of hoped I could use an OR operator of some kind but can't quite figure that out (Python responds to False or 'bob' with 'bob'). Hence, yet again, I appeal to you beautiful Rstats people for help!

• How to compare 2 complex spreadsheets running in parallel for consistency with each other?

  - by tbone

  I am working on converting a large number of spreadsheets to use a new 3rd party data access library (converting from third party library #1 to third party library #2). fyi: a call to a UDF (user defined function) is placed in a cell, and when that is refreshed, it pulls the data into a pivot table below the formula. Both libraries behave the same and produce the same output, except, small irregularites can arise, such as an additional field being shown in the output pivot table using library #2, which can affect formulas on the sheet if data is being read from the pivot table without using GetPivotData. So I have ~100 of these very complicated (20+ worksheets per workbook) spreadsheets that I have to convert, and run in parallel for a period of time, to see if the output using the new data access library matches the old library. Is there some clever approach to do this, so I don't have to spend a large amount of time analyzing each sheet to determine the specific elements to compare? Two rough ideas that come to mind: 1. just create a Validator workbook that has the same # of worksheets, and simply do a Worbook1!Worksheet1!A1 - Worbook2!Worksheet3!A1 for every possible cell on each sheet 2. roughly the equivalent of #1, but just traverse the cells in the 2 books using VBA, and log any cells that do not match. I don't particularly like either idea, can anyone think of something better than this, maybe some 3rd party utility I could buy?

• How to display two ObservableCollections as a single list in WPF?

  - by nareshbhatia

  I have two ObservableCollections, say ObservableCollection<Cat> and ObservableCollections<Dog>. Cat and Dog both derive from class Pet. I want to display a list of all Pets. How do I do this? I prefer not want create a new ObservableCollection<Pet> by adding items from the two source lists because this list will become stale as more Cats and Dogs are added to the source lists. I can think of two approaches: 1) Create a "Decorator" ObservableCollection that keeps the two source collections as members and iterates over them every time. 2) Create an ObservableCollection<Pet> that does have the combined elements of the two source collections, but is also dependent on the source collections. Thus if a Cat is added to the Cat collection, this collection is notified and it adds the new Cat to itself. Is there a standard way to solve this issue? I don't want to reinvent the wheel!

• Page content layout issues

  - by Prupel

  I'm designing a theme for a blog and I'm having some trouble trying to get a layout working. Here's an image of what I want. This diagram represents the individual posts and not the website itself, so it will be contained in a box of it's own, lets call it .container. Also the purple and green are in another box, let's call it .content. The other elements will be called by their color for now. so here's more or less what the CSS looks like: .container { display:block; margin:0 25px; } .gray, .blue, .content { display:block; width:100%; } .purple { display:inline-block; width:125px; height:100%; text-align:center; } .green { display:inline-block; } That's all there is at the moment. I tried float but that made no effect. What's happening is something like this. Here's a few more things you should know: .container's width is NOT set it is auto .purple and .green don't necessarily need to be the same size as long as .green doesn't go to that side. .purple CAN have a set height .green is where the meat is, that's where the actual post goes, keep that in mind. I don't think tables will help, the problem is inside .content.

• Can I flow divs down the page instead of across it?

  - by Brabster

  If I have a collection of div elements, I can use CSS to have them flow across the page and overflow onto the next line. Here's a simple example: <html> <head> <title>Flowing Divs</title> <style type="text/css"> .flow { float: left; margin: 4em 8em; } </style> </head> <body> <div class="container"> <div class="flow">Div 1</div> <div class="flow">Div 2</div> <div class="flow">Div 3</div> <div class="flow">Div 4</div> <div class="flow">Div 5</div> <div class="flow">Div 6</div> <div class="flow">Div 7</div> <div class="flow">Div 8</div> </div> </body> </html> Is it possible to have the divs flow down the page instead of across it, so that they would flow down columns not along lines, but still occupy the same space as they would if they flowed across? So for the example above, if they flowed into two lines of four divs, could I get the first column to contain Div1 and Div2 instead of Div1 and Div5?

• Javascript: Check if checkboxes are selected on page load and add a class to parent html li

  - by BoDiE2003

  Im looking a way to do it with prototype, this js, needs to loads with the page and interate over all the elements (inputs - checkboxes, in this case) with the given id and assign a class to its parent <li></li> The JS is: function changeSelectionStyle(id) { var inputId = id.substr(0,id.length-2); if(document.getElementById(inputId).checked){document.getElementById(id).className = 'yes';} alert(document.getElementById(inputId).checked); /* * if(document.getElementById(id).className != 'yes'){ * document.getElementById(id).className = 'yes'; * } else{document.getElementById(id).className = '';} */ } And the HTML (piece of it) that interacts with this JS is: <li id="selectedAuthorities-4_1li"> <input type="checkbox" id="selectedAuthorities-4_1" name="selectedAuthorities" value="ROLE_ADD_COMMENT_TO_CV" checked="checked" onclick="changeSelectionStyle(this.id + 'li'); checkFatherSelection(this.id);"> <a href="#" onclick="document.getElementById('selectedAuthorities-4_1').click(); return false;"> Agregar comentario <samp><b></b>Permite agregar comentario en el detalle</samp> </a> </li> After iteration, checking is the checkbox is checked, it has to add the class="yes" to the <li id="selectedAuthorities-4_1li">

• Modifying CSS class property values on the fly with JavaScript / jQuery

  - by JPN

  all. I've run into a unique situation that I have so far been unable to find a solution for: dynamically assigning a value to a CSS style. I know how to use jQuery to assign width, height, etc. to an element, but what I'm trying to do is actually change the value defined in the stylesheet so that the dynamically-created value can be assigned to multiple elements. What I'm building is a slideshow of images that occupy the full viewport, recalculating the image's width, height, and left properties on resize so that the image is always centered, favors width over height, except when the viewport is taller than it is wide (resizing does not reload the page, just fires a function to resize the image). I have successfully been able to get it to work on one image, and now I'm trying to determine the best way to assign those property values to all images in the slideshow without having to specify those three things individually for every image. Can the values of properties in a class be modified on the fly? I'm sure the answer is out there, I'm probably just not using the correct terminology in my searches. Hope I did a good job of describing the problem. TIA.

• Issues with intellisense, references, and builds in Visual Studio 2008

  - by goober

  Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give!

• reactivating or binding a hover function in jquery??

  - by mathiregister

  hi guys, with the following three lines: $( ".thumb" ).bind( "mousedown", function() { $('.thumb').not(this).unbind('mouseenter mouseleave'); }); i'm unbinding this hover-function: $(".thumb").hover( function () { $(this).not('.text, .file, .video, .audio').stop().animate({"height": full}, "fast"); $(this).css('z-index', z); z++; }, function () { $(this).stop().animate({"height": small}, "fast"); } ); i wonder how i can re-bind the exact same hover function again on mouseup? the follwoing three lines arent't working! $( ".thumb" ).bind( "mouseup", function() { $('.thumb').bind('mouseenter mouseleave'); }); to get what i wanna do here's a small explanation. I want to kind of deactivate the hover function for ALL .thumbs-elements when i click on one. So all (but not this) should not have the hover function assigned while i'm clicking on an object. If i release the mouse again, the hover function should work again like before. Is that even possible to do? thank you for your help!

• Get location of element you just pushed into vector C++

  - by Satchmo Brown

  I am curious about how pushing back into a vector works. I want a way to push back an element and then be able to add it's location in the vector to a double array serving as a type of map. Something like this: // Create a bomb Bomb b; b.currentTime = SDL_GetTicks(); b.explodeTime = SDL_GetTicks() + 3000; b.owner = player; b.power = 2; b.x = x; b.y = y; bombVec.push_back(b); bombs[y][x] = THIS_IS_WHAT_I_WANT; This way when I explode the bomb, I can check the map and then have an ID in the vector to deal with. Every non bomb square will have a -1. Also, just curious. Imagine I have 3 elements in a vector. I delete the second one and then add another. Does the new element go in the same location as the one that was deleted? Thanks!

• javaScript .splice() not working on correctly

• jQuery: Moving window (or FIFO) type DIV?

  - by Legend

  I have been trying to get this effect for a couple of hours now and I must admit I am failing at it. I am trying to construct a DIV that accepts a particular number of items (say 5), when the 6th item is added, the first item that was aded should be removed (first-in-first-out). The feel should have some kind of a fadeIn and fadeOut. Here's what I managed to write till now: ... //Create a ul element with id 'ulele' and add it to a div ... //Do an ajax call and when an element arrives Hash = ComputeHash(message) if(!$("#" + Hash).exists()) { var element = $("<li></li>").html(message).attr('id', Hash).prependTo("#ulele"); $("#" + Hash).hide().delay(10000 - 1000 * messageNumber).show("slow"); _this.prune("#ulele"); } ... prune: function(divid) { $("#" + divid).children().each( function(i, elemLi) { if(i >= maxMessages) $(this).delay(10000).hide("slow").delay(10000).remove(); } ); } I've tried a couple of variations but the final effect I am getting is not that of a FIFO. The elements disappear instantaneously despite the delay and hide("slow") calls. Anyone has a more straightforward approach?

• Does CSS have a "start over" feature?

  - by Rick Wayne

  I'm using calendar_date_select (henceforth CDS) in a Rails application, and have a stupid question. When I embed the CDS component in the middle of an already-CSS-styled page, all manner of things go ugly-wrong with it (spacing, fonts, etc.). Clearly the elements inside the CDS have inherited unwanted stuff from the styles already working in the containing page. Now, I could use a combination of, say, Safari's CSS debugging and analyze what's wrong element-by-element. But that's (A) tedious, and (B) might load up my component's styles with tons of container-defeating special cases. If nothing else, I'm certain to change the containing page's styles in the future and would have to maintain the special cases. My question: Is is possible to have a DIV in a page that essentially backs out all the existing styling? Is there a simple one-liner that will do this? Failing that, can it be done on an element-by-element basis? E.g. I know what tags the CDS generates, so I could list each of them: { p: "#--NOTHING--#"; a: "#--NOTHING--#"; } where #--NOTHING--# is the Magic Turn Off All Inherited Styles incantation. http://code.google.com/p/calendardateselect/ Thanks, peeps.

• ASP.NET page with base class with dynamic master page not firing events

  - by Kangkan

  Hi guys! I am feeling that I have terribly wrong somewhere. I was working on a small asp.net app. I have some dynamic themes in the \theme folder and have implemented a page base class to load the master page on the fly. The master is having the ContentPlaceHolder like: <asp:ContentPlaceHolder ID="cphBody" runat="server" /> Now I am adding pages that are derived from my base class and added the form elements. I know, Visual Studio has problem showing the page in the design mode. I have a dropdown box and wish to add the event of onselectedindexchange. But it is not working. the page is like this: <%@ Page Language="C#" AutoEventWireup="true" Inherits="trigon.web.Pages.MIS.JobStatus" Title="Job Status" AspCompat="true" CodeBehind="JobStatus.aspx.cs" %> <asp:Content ID="Content1" ContentPlaceHolderID="cphBody" runat="Server"> <div id="divError" runat="server" /> <asp:DropDownList runat="server" id="jobType" onselectedindexchange="On_jobTypeSelection_Change"></asp:DropDownList> </asp:Content> I have also tried adding the event on the code behind like: protected void Page_Load(object sender, EventArgs e) { jobType.SelectedIndexChanged += new System.EventHandler(this.On_jobTypeSelection_Change); if (!IsPostBack) { JobStatus_DA da = new JobStatus_DA(); jobType.DataSource = da.getJobTypes(); jobType.DataBind(); } } protected void On_jobTypeSelection_Change(Object sender, EventArgs e) { //do something here } Can anybody help? Regards,
