  • NSInvocationOperation and main thread

    - by kpower
    Imagine that I have a view with some UIKit object as its subview (for example, UIActivityIndicatorView - this doesn't matter). This view also has a selector, called doSomething, which somehow manages UIKit object (in our example it can start or stop indicator view). I create NSInvocationOperation (from view's code parts) with initWithTarget:self selector:@selector(doSomething) object:nil. Then add it to NSOperationQueue. And all works fine. How?! It should be a new thread and non-thread-safe UIKit object! Why no error found (and no crash happened)?

  • Activity in Android

    - by leduchuy89vn
    Normally, a Java p'rogram starts from an object, then that object will create some GUI objects (window) and call the "Show" method So, is there any way to do the same thing in Android, since, by default in Android, a program runs from an object created by a class which extended from Activity class?

  • Assign a unique client ID to each <rich:dataTable /> row?

    - by Dolph Mathews
    I'm relatively new to working with the UI in Seam, so I'm hoping there is something simple I can replace the three instances of UNIQUE_ID with in the following example (such as #{object.uniqueId}). The goal is to have a <rich:dataTable /> wherein each row has the ability to show/hide a <rich:modalPanel /> with more details about the particular object instance. <rich:dataTable var="object" value="#{bean.myObject}"> <rich:column> <h:outputText value="#{object.summary}" /> </rich:column> <rich:column> <a onclick="Richfaces.showModalPanel('UNIQUE_ID');" href="#">Show Details in ModalPanel</a> <a4j:form> <rich:modalPanel id="UNIQUE_ID" > <a onclick="Richfaces.hideModalPanel('UNIQUE_ID');" href="#">Hide This ModalPanel</a> <h:outputText value="#{object.details}" /> </rich:modalPanel> </a4j:form> </rich:column> </rich:dataTable> If I only had one link/modalPanel pair, this would obviously be trivial, but I don't know what to do within the scope of the <rich:dataTable />'s iteration. Also, in case it complicates things further, the page will also contain many <rich:dataTable />'s, each implementing this behavior.

  • jqModal and jquery widget long shot

    - by rod
    Hi All, I just started playing around with jquery widgets within my jqmodals in my mvc app. I know this may be a long shot but I'll take it. Initially, I can click the Add link, get the alert ("which is the prize", watching too much tv), next click cancel to close modal and get the desired results. I can, then, click the Edit link and get the same desired results. However, if I click Edit link first then I try to click the Add link, "forget about it" I don't get the alert (which means my widget did not init). But I can still go back and click Edit and get the prize (the alert message). ajax: "/Home/EditPrintAdLine" and ajax: "/Home/AddPrintAdLine" render the same web user control Any ideas? <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="indexTitle" ContentPlaceHolderID="TitleContent" runat="server"> Home Page </asp:Content> <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(ViewData["Message"]) %></h2> <p> To learn more about ASP.NET MVC visit <a href="http://asp.net/mvc" title="ASP.NET MVC Website">http://asp.net/mvc</a>. </p> <div id="printAdLineEditDialog" class="jqmWindow"></div> <div id="printAdDialog" class="jqmWindow"></div> <table> <tr><td><a id="printAdLineItem" href="#">Add a Line Item</a></td></tr> <tr><td><a id="editPrintAdLine" href="#">Edit</a></td></tr> </table> <script type="text/javascript"> $(document).ready(function() { $.widget("ui.my_widget", { _init: function() { alert("My widget was instantiated"); } }); // Add line $('#printAdLineItem').click(function(e) { $('#printAdDialog').jqmShow(this); e.preventDefault(); }); $('#printAdDialog').jqm({ ajax: "/Home/AddPrintAdLine", onLoad: function(hash) { $('#PrintAdLine_RunDate').my_widget(); } }); // Edit line $('#editPrintAdLine').click(function(e) { $('#printAdLineEditDialog').jqmShow(this); e.preventDefault(); }); $('#printAdLineEditDialog').jqm({ ajax: "/Home/EditPrintAdLine", onLoad: function(hash) { $('#PrintAdLine_RunDate').my_widget(); } }); }); </script> </asp:Content>

  • Why wont this JS code work if its all on the same line?

    - by culov
    I'm writing HTML code for a java servlet. i first write the code in html/js so i can debug what im working on, and then ill make it a java string and put it in my servlet. My problem is that the code is working fine when i view it in ff from a local html file, but when i view it on my java servlet, it doesnt work because the js isnt getting called. what I did was format the html that my servlet generated so that its not all on a single line and ran the code again. This time it worked. I copied this working code into a browser address bar so that it will all be on a single line, and copied that code back into the script in my html file. Now, when the previously working code is on a single line, it doesnt work. Here's the formatted JS: var sMax var holder; var preSet; var rated; var request; function rating(num){ sMax = 0; for(n=0; n<num.parentNode.childNodes.length; n++){ if(num.parentNode.childNodes[n].nodeName == "A"){ sMax++; } } if(!rated){ s = num.id.replace("_", ''); a = 0; for(i=1; i<=sMax; i++){ if(i<=s){ document.getElementById("_"+i).className = "on"; document.getElementById("rateStatus").innerHTML = num.title; holder = a+1; a++; }else{ document.getElementById("_"+i).className = ""; } } } } function off(me){ if(!rated){ if(!preSet){ for(i=1; i<=sMax; i++){ document.getElementById("_"+i).className = ""; document.getElementById("rateStatus").innerHTML = me.parentNode.title; } }else{ rating(preSet); document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML; } } } function rateIt(me){ if(!rated){ document.getElementById("rateStatus").innerHTML = document.getElementById("ratingSaved").innerHTML + " "+me.title; preSet = me; rated=1; sendRate(me); rating(me); } } function sendRate(sel){ alert("Your rating was: "+sel.title); addRating("rating", "?truck=kogibbq?rating="+ sel.id); } function addRating(servletName, servletArguments){ var servlet = servletName; var arg = servletArguments var req = servlet + arg; alert(req); addrequest(req); request.onreadystatechange = function(){ alert("response received"); } } function addrequest(req) { try { request = new XMLHttpRequest(); }catch (e) { try { request = new ActiveXObject("Microsoft.XMLHTTP"); }catch (e) { alert("XMLHttpRequest error: " + e); } } request.open("GET", element, true); request.send(null); return request; } Thanks.

  • How to retrive message list from p2p

    - by cre-johnny07
    Hello friends I have a messaging system that uses p2p. Each peer has a incoming message list and a outgoing message list. What I need to do is whenever a new peer will join the mesh he will get the all the incoming messages from other peers and add those into it's own incoming message list.

    I have a dropdown list that I want to show only certain options when a bool is true of false. if (mainForm.boolEdit == true) { this.cmbStatusBox.Items.AddRange(new object[] { "Cooking", "In-transit", "Delivered"}); } else { this.cmbStatusBox.Items.AddRange(new object[] { "Ordered"}); } I put this code into the saveForm.Designer.cs and got the following error: The designer cannot process the code at line 205: if (mainForm.boolEdit == true) { this.cmbStatusBox.Items.AddRange(new object[] { "Cooking", "In-transit", "Delivered"}); } else { this.cmbStatusBox.Items.AddRange(new object[] { "Ordered"}); } The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again. What are my alternatives?

  • Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • JavaScript on jQuery created code never gets called

    This is my view in ASP.NET MVC. <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Administration.Master" Inherits="System.Web.Mvc.ViewPage" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="HeadContent" runat="server"> <script type="text/javascript"> var ddlContentTypes; $(document).ready(function () { ddlContentTypes = $("#ContentTypes"); ddlContentTypes.bind("change", loadCreate); loadCreate(); }); function loadCreate() { var typeId = $("#ContentTypes option:selected").val(); $.get('~/' + typeId + '/Create', function (data) { $("#CreateForm").html(data); }); $("fieldset input").each(function (index, item) { $(item).attr("disabled", true); }); } </script> </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server"> <h2> <%=Resources.Localize.CreateWidget %></h2> <p> <% Html.RenderPartial("ContentTypeSelector"); %></p> <div id="CreateForm"> </div> </asp:Content> As you can see, it loads some HTML (actually user control) and adds it to the CreateForm div. This actually works fine. The problem is this $("fieldset input").each(function (index, item) { $(item).attr("disabled", true); }); never runs. The fieldset tag is in the response, so you don't see it here but it's there - everything is returned back fine (I checked with Firebug). Why do the above two lines of JS never run or have any effect?

  • ActionScript: Type coercion problem with BlazeDS/AMF and class interfaces

    - by mike
    Hi, I've got a problem with type coercion in a Java/Hibernate/BlazeDS/Flex-Setup. First of all, my classes look like this: --- JAVA --- Interface I (Abstract) Class A implements I Class B extends A --- ActionScript --- Interface I Class A implements I Class B extends A I got RemoteClass-Meta-Tags in all ActionScript-Classes/Interfaces I, A and B. Package structure and Class/Interface names are exactly the same. Now here's the problem: My Java Service successfully retrieves objects of class B from my database via Hibernate. I got another class C which has a member property of interface type I, so it should be possible to assign an object of type B. But for some reason i get the following error message: TypeError: Error #1034: cannot convert Object@28b44a89 to package.name.I I checked the Java object type in the service and it is of type B and seems to be totally fine. Why can't the object of type B be assigned to a member variable of type I? This is driving me nuts. Thanks in advance.

  • .NET Programmatically invoke screenclick doesn't work?

    I'm trying to programmatically invoke an onclick event however the click is not received/handled. Am I missing something, or is security preventing the click to be executed?

  • JQuery animate div "like" a Zoom

    - by Russell Parrott
    I can never get these to work - sorry - but I I am trying to animate on a mouse over then "re-animate" on a mouse out. I can never get $('#xyz').hover(function(){'something',function(){'somethingelse'}); to work. Hope you guys can help. What I am trying to do is animate + and - 20px (top and left) on some absolutely positioned divs and then add 40px to the width height returning to the original position/width/height on mouse out. I haven't even got to the css widths/heights yet .... Here is my code (which is wrong - well it must be as it doesn't work :-) ) $('.box').hover(function(){ $(this).animate({'top':'-20','left':'-20'},function(){ $(this).animate({'top':'20','left':'20' }); }); Help really appreciated. Thanks in advance

  • trying to fade out a top div on hover to reveal working links in text below using JQuery

    - by Heath
    I need to fade a div (and image) to reveal a div underneath (text with clickable links) using jQuery. <script> $(document).ready(function(){ $("img.a").hover( function() { $(this).stop().animate({"opacity": "0"}, "slow"); }, function() { $(this).stop().animate({"opacity": "1"}, "slow"); }); }); </script> Used the above code and all worked well, until I went to click the links. Seems the top hidden div is preventing me from doing so. Tried the replaceWith function and that allowed me to click the links too - but couldn't get it to go back to showing original div when I moused out. Also, bossman wants the transition to be gradual - like a fade... Any suggestions? Many thanks! Heath

  • Why does this valid Tkinter code crash when mixed with a bit of PyWin32?

    - by Erlog
    So I'm making a very small program for personal use in tkinter, and I've run into a really strange wall. I'm mixing tkinter with the pywin32 bindings because I really hate everything to do with the syntax and naming conventions of pywin32, and it feels like tkinter gets more done with far less code. The strangeness is happening in the transition between the pywin32 clipboard watching and my program's reaction to it in tkinter. My window and all its controls are being handled in tkinter. The pywin32 bindings are doing clipboard watching and clipboard access when the clipboard changes. From what I've gathered about the way the clipboard watching pieces of pywin32 work, you can make it work with anything you want as long as you provide pywin32 with the hwnd value of your window. I'm doing that part, and it works when the program first starts. It just doesn't seem to work when the clipboard changes. When the program launches, it grabs the clipboard and puts it into the search box and edit box just fine. When the clipboard is modified, the event I want to fire off is firing off...except that event that totally worked before when the program launched is now causing a weird hang instead of doing what it's supposed to do. I can print the clipboard contents to stdout all I want if the clipboard changes, but not put that same data into a tkinter widget. It only hangs like that if it starts to interact with any of my tkinter widgets after being fired off by a clipboard change notification. It feels like there's some pywin32 etiquette I've missed in adapting the clipboard-watching sample code I was using over to my tkinter-using program. Tkinter apparently doesn't like to produce stack traces or error messages, and I can't really even begin to know what to look for trying to debug it with pdb. Here's the code: #coding: utf-8 #Clipboard watching cribbed from ## {{{ http://code.activestate.com/recipes/355593/ (r1) import pdb from Tkinter import * import win32clipboard import win32api import win32gui import win32con import win32clipboard def force_unicode(object, encoding="utf-8"): if isinstance(object, basestring) and not isinstance(object, unicode): object = unicode(object, encoding) return object class Application(Frame): def __init__(self, master=None): self.master = master Frame.__init__(self, master) self.pack() self.createWidgets() self.hwnd = self.winfo_id() self.nextWnd = None self.first = True self.oldWndProc = win32gui.SetWindowLong(self.hwnd, win32con.GWL_WNDPROC, self.MyWndProc) try: self.nextWnd = win32clipboard.SetClipboardViewer(self.hwnd) except win32api.error: if win32api.GetLastError () == 0: # information that there is no other window in chain pass else: raise self.update_search_box() self.word_search() def word_search(self): #pdb.set_trace() term = self.searchbox.get() self.resultsbox.insert(END, term) def update_search_box(self): clipboardtext = "" if win32clipboard.IsClipboardFormatAvailable(win32clipboard.CF_TEXT): win32clipboard.OpenClipboard() clipboardtext = win32clipboard.GetClipboardData() win32clipboard.CloseClipboard() if clipboardtext != "": self.searchbox.delete(0,END) clipboardtext = force_unicode(clipboardtext) self.searchbox.insert(0, clipboardtext) def createWidgets(self): self.button = Button(self) self.button["text"] = "Search" self.button["command"] = self.word_search self.searchbox = Entry(self) self.resultsbox = Text(self) #Pack everything down here for "easy" layout changes later self.searchbox.pack() self.button.pack() self.resultsbox.pack() def MyWndProc (self, hWnd, msg, wParam, lParam): if msg == win32con.WM_CHANGECBCHAIN: self.OnChangeCBChain(msg, wParam, lParam) elif msg == win32con.WM_DRAWCLIPBOARD: self.OnDrawClipboard(msg, wParam, lParam) # Restore the old WndProc.

  • which is the most secure way to check variables type javascript

    - by mck89
    Hi, i need to check the type of a variable in javascript, i know 3 ways to do it: instanceof operator: if(a instanceof Function) typeof operator: if(typeof a=="function" toString method (jQuery uses this): Object.prototype.toString.call(a) == "[object Function]" Which is the most secure way to do type checking beetween these solutions? and why? Please don't tell me that the last solution is better only because jQuery uses that.

  • Managing multiple AJAX calls to PHP scripts

    - by relativelycoded
    I have a set of 5 HTML dropdowns that act as filters for narrowing results returned from a mySQL database. The three pertinent filters are for "Province", "Region", and "City" selection, respectively. I have three functions: findSchools(), which runs when any of the filters (marked with CSS class .filter) are changed, and fetches the results via AJAX from a PHP script. Once that is done, two other functions are called... changeRegionOptions(), which, upon changing the "Province" filter, and updates the available options using the same method as the first function, but posting to a different script. changeCityOptions(), which runs if the "Region" filter was changed, and updates options, again using the same method. The problem is that since I want these AJAX functions to run simultaneously, and they by nature run asynchronously, I've tried using $.when to control the execution of the functions, but it doesn't fix the problem. The functions run, but the Region and City filters return blank (no options); the FireBug report shows absolutely no output, even though the POST request went through. The posted parameter for filter_province gets sent normally, but the one for region gets cut off at the end -- it sends as filter_region=, with no value passed. So I'm presuming my logic is wrong somewhere. The code is below: // When any of the filters are changed, let's query the database... $("select.filter").change(function() { findSchools(); }); // First, we see if there are any results... function findSchools() { var sch_province = document.filterform.filter_province.value; var sch_region = document.filterform.filter_region.value; var sch_city = document.filterform.filter_city.value; var sch_cat = document.filterform.filter_category.value; var sch_type = document.filterform.filter_type.value; $.post("fetch_results.php", { filter_province : sch_province, filter_region : sch_region, filter_city : sch_city, filter_category : sch_cat, filter_type : sch_type }, function(data) { $("#results").html(""); $("#results").hide(); $("#results").html(data); $("#results").fadeIn(600); } ); // Once the results are fetched, we want to see if the filter they changed was the one for Province, and if so, update the Region and City options to match that selection... $("#filter_province").change(function() { $.when(findSchools()) .done(changeRegionOptions()); $.when(changeRegionOptions()) .done(changeCityOptions()); }); }; This is just one of the ways I've tried to solve it; I've tried using an IF statement, and tried calling the functions directly inside the general select.filter.change() function (after findSchools(); ), but they all return the same result. Any help with this would be great!

  • XSLT - make xsl:analyze-string return string instead of sequence of strings?

    - by tohuwawohu
    Is it possible to make xsl:analyze-string return one string instead of a sequence of strings? Background: I'd like to use xsl:analyze-string in a xsl:function that should encapsulate the pattern matching. Ideally, the function should return an xs:string to be used as sort criteria in an xsl:sort element. At the moment, i have to apply string-join() on every result of the function call since xsl:analyze-string returns a sequence of strings, and xsl:sort doesn't accept such a sequence as sort criteria. See line 24 of the stylesheet: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:my="www.my-personal-namespa.ce" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xsl:output indent="yes" method="xml" /> <xsl:function name="my:sortierung" > <xsl:param name="inputstring" as="xs:string"/> <xsl:analyze-string select="$inputstring" regex="[0-9]+"> <xsl:matching-substring> <xsl:value-of select="format-number(number(.), '00000')" /> </xsl:matching-substring> <xsl:non-matching-substring> <xsl:value-of select="." /> </xsl:non-matching-substring> </xsl:analyze-string> </xsl:function> <xsl:template match="/input"> <result> <xsl:apply-templates select="value" > <xsl:sort select="string-join((my:sortierung(.)), ' ')" /> </xsl:apply-templates> </result> </xsl:template> <xsl:template match="value"> <xsl:copy-of select="." /> </xsl:template> </xsl:stylesheet> with this input: <?xml version="1.0" encoding="UTF-8"?> <input> <value>A 1 b 120</value> <value>A 1 b 1</value> <value>A 1 b 2</value> <value>A 1 b 1a</value> </input> In my example, is there a way to modify the xsl:function to return a xs:string instead of a sequence?

  • .Net Dynamically Load DLL

    - by hermiod
    I am trying to write some code that will allow me to dynamically load DLLs into my application, depending on an application setting. The idea is that the database to be accessed is set in the application settings and then this loads the appropriate DLL and assigns it to an instance of an interface for my application to access. This is my code at the moment: Dim SQLDataSource As ICRDataLayer Dim ass As Assembly = Assembly. _ LoadFrom("M:\MyProgs\WebService\DynamicAssemblyLoading\SQLServer\bin\Debug\SQLServer.dll") Dim obj As Object = ass.CreateInstance(GetType(ICRDataLayer).ToString, True) SQLDataSource = DirectCast(obj, ICRDataLayer) MsgBox(SQLDataSource.ModuleName & vbNewLine & SQLDataSource.ModuleDescription) I have my interface (ICRDataLayer) and the SQLServer.dll contains an implementation of this interface. I just want to load the assembly and assign it to the SQLDataSource object. The above code just doesn't work. There are no exceptions thrown, even the Msgbox doesn't appear. I would've expected at least the messagebox appearing with nothing in it, but even this doesn't happen! Is there a way to determine if the loaded assembly implements a specific interface. I tried the below but this also doesn't seem to do anything! For Each loadedType As Type In ass.GetTypes If GetType(ICRDataLayer).IsAssignableFrom(loadedType) Then Dim obj1 As Object = ass.CreateInstance(GetType(ICRDataLayer).ToString, True) SQLDataSource = DirectCast(obj1, ICRDataLayer) End If Next EDIT: New code from Vlad's examples: Module CRDataLayerFactory Sub New() End Sub ' class name is a contract, ' should be the same for all plugins Private Function Create() As ICRDataLayer Return New SQLServer() End Function End Module Above is Module in each DLL, converted from Vlad's C# example. Below is my code to bring in the DLL: Dim SQLDataSource As ICRDataLayer Dim ass As Assembly = Assembly. _ LoadFrom("M:\MyProgs\WebService\DynamicAssemblyLoading\SQLServer\bin\Debug\SQLServer.dll") Dim factory As Object = ass.CreateInstance("CRDataLayerFactory", True) Dim t As Type = factory.GetType Dim method As MethodInfo = t.GetMethod("Create") Dim obj As Object = method.Invoke(factory, Nothing) SQLDataSource = DirectCast(obj, ICRDataLayer) EDIT: Implementation based on Paul Kohler's code Dim file As String For Each file In Directory.GetFiles(baseDir, searchPattern, SearchOption.TopDirectoryOnly) Dim assemblyType As System.Type For Each assemblyType In Assembly.LoadFrom(file).GetTypes Dim s As System.Type() = assemblyType.GetInterfaces For Each ty As System.Type In s If ty.Name.Contains("ICRDataLayer") Then MsgBox(ty.Name) plugin = DirectCast(Activator.CreateInstance(assemblyType), ICRDataLayer) MessageBox.Show(plugin.ModuleName) End If Next I get the following error with this code: Unable to cast object of type 'SQLServer.CRDataSource.SQLServer' to type 'DynamicAssemblyLoading.ICRDataLayer'. The actual DLL is in a different project called SQLServer in the same solution as my implementation code. CRDataSource is a namespace and SQLServer is the actual class name of the DLL. The SQLServer class implements ICRDataLayer, so I don't understand why it wouldn't be able to cast it. Is the naming significant here, I wouldn't have thought it would be.

  • Can't print elements in a DIV tag

  • What is the appropriate terminology in Java when building remote proxies?

    - by Uri
    Suppose that I am implementing a remote proxy in Java to an object that is likely to reside on a remote server but may reside locally. There's my real object on the remote server, there's the local implementation (the proxy itself), and there's the interface I provide to my program which hides the details of where the object actually is. The local representation may contact a local or a remote implementation of the object. What is the standard terminology in Java for these things? What should I name my interfaces/classes? I've seen the terms Subjects, Images, and Implementations thrown around (probably from the GOF days), but I wonder what is acceptable way to do the naming for a framework written in Java.
