  • Silverlight + ItemsControl + Get Control Property Value

    - by Villager
    Hello, I have an ItemsControl with a DataTemplate that has been defined. My ItemsControl definition looks like the following: <ItemsControl x:Name="myItemsControl" ItemsSource="{Binding}"> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <CheckBox x:Name="myCheckBox" Content="{Binding Name}" /> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> This is a simplified version of my DataTemplate. Regardless, when a user clicks a button on the page, I want to loop through the items in myItemsControl and determine if the CheckBox element associated with the item is checked. How do I determine if a CheckBox is checked for a specific item within an ItemsControl? Thank you!

    Hi, I have a small sql question. I have 2 tables Members and Managers Members has: memberID, Name, Address Managers has: memberID, EditRights, DeleteRights EditRights and DeleteRights are of type bit. Mangers have a relationship with Members, because they are members themselves. I want to select all members id's, name and adress and for the members that are managers show if they have editrights and/or deleterights. SO: Exmaple data Members: ID, Name, Address 1, tom, 2 flat 2, dan, 3 flat 3, ben, 4 flat 4, bob, 6 flat 5, sam, 9 flat Managers: ID, Editrights, deleterights 2, 0, 1 4, 1, 1 5, 0, 0 I would like to display a select like this: 1, tom, 2 flat, no rights 2, dan, 3 flat, Delete 3, ben, 4 flat, no rights 4, bob, 6 flat, Edit&Delete 5, sam, 9 flat, no rights Any help would be great

  • Generating code for service proxies

    - by Hadi Eskandari
    I'm trying to generate some additional code base on the auto-generated webservice proxies in my VS2010 solution, I'm using a T4 template to do so. The problem is, automatically generated proxies are added in "Service Reference" folder but ProjectItems (files) are hidden by default and the following code does not find them in the project structure: var sr = GetProjectItem(project, "Service References"); if(sr != null) { foreach(ProjectItem item in sr.ProjectItems) { foreach(var file in item.ProjectItems) { //Services.Add(new ServiceInfo { Name = file.Name }); } } } The above code runs and although service reference is found, and there are ProjectItems under that node (named by the webservice reference name), under object under that node is of type System.__ComObject and I'm not sure how to progress. Any help is appreciated.

  • JQuery validation - how to set the title attribute to the error message

    - by JK
    In JQuery validation the default behavior on an error is to create a label like so: <label for="FirstName" generated="true" class="error">This field is required.</label> Is it possible to change it so that it will output this instead (with a title attribute set to the error message)? <label for="FirstName" generated="true" class="error" title="This field is required.">This field is required.</label> I've tried the highlight method, but the label has not been created yet: $("#form").validate({ highlight: function (element, errorClass) { var label = $("label[for=" + element.id + "]"); // but label doesn't exist yet so this doesnt work if (label && label.length > 0) { // label.length is always 0 label.attr('title', label.text()); } } });

  • Flash AS3 button eventlistener array bug

    - by Tyler Pepper
    Hi there, this is my first time posting a question here. I have an array of 12 buttons on a timeline that when first visiting that part of the timeline, get a CLICK eventlistener added to them using a for loop. All of them work perfectly at that point. When you click one it plays a frame label inside the specific movieClip and reveals a bio on the corresponding person with a close button and removes the CLICK eventlisteners for each button, again using a for loop. The close button plays a closing animation, and then the timeline goes back to the first frame (the one with the 12 buttons on it) and the CLICK eventlisteners are re-added, but now only the first 9 buttons of the array work. There are no output errors and the code to re-add the eventlisteners is exactly the same as the first time that works. I am completely at a loss and am wondering if anyone else has run into this problem. All of my buttons are named correctly, there are absolutely no output errors (I've used the debug module) and I made sure the array with the buttons in it is outputting all 12 at the moment the close button is clicked to add the eventlisteners back. for (var q = 0; q < ackBoDBtnArray.length; q++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[q]].addEventListener(MouseEvent.CLICK, showBio); } private function showBio(eo:MouseEvent):void { trace("show the bio"); bodVar = ackBoDBtnArray.getIndex(eo.target.name); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDPgArray[bodVar]); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.addEventListener(MouseEvent.CLICK, hideBio); for (var r = 0; r < ackBoDBtnArray.length; r++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].mouseEnabled = false; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].removeEventListener(MouseEvent.CLICK, showBio); } } private function hideBio(eo:MouseEvent):void { trace("hide it!"); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.removeEventListener(MouseEvent.CLICK, hideBio); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDClosePgArray[bodVar]); for (var s = 0; s < ackBoDBtnArray.length; s++){ trace(ackBoDBtnArray[s]); contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].mouseEnabled = true; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].addEventListener(MouseEvent.CLICK, showBio); } Thanks in advance for any help and insight you can provide...I have a slight feeling that its something that may be obvious to another set of eyes...haha.

  • Bash: using commands as parameters (specifically cd, dirname and find)

    - by sixtyfootersdude
    This command and output: % find . -name file.xml 2> /dev/null ./a/d/file.xml % So this command and output: % dirname `find . -name file.xml 2> /dev/null` ./a/d % So you would expect that this command: % cd `dirname `find . -name file.xml 2> /dev/null`` Would change the current directory to ./a/d. Strangely this does not work. When I type cd ./a/d. The directory change works. However I cannot find out why the above does not work...

  • How to get compatibility between C# and SQL2k8 AES Encryption?

    - by Victor Rodrigues
    I have an AES encryption being made on two columns: one of these columns is stored at a SQL Server 2000 database; the other is stored at a SQL Server 2008 database. As the first column's database (2000) doesn't have native functionality for encryption / decryption, we've decided to do the cryptography logic at application level, with .NET classes, for both. But as the second column's database (2008) allow this kind of functionality, we'd like to make the data migration using the database functions to be faster, since the data migration in SQL 2k is much smaller than this second and it will last more than 50 hours because of being made at application level. My problem started at this point: using the same key, I didn't achieve the same result when encrypting a value, neither the same result size. Below we have the full logic in both sides.. Of course I'm not showing the key, but everything else is the same: private byte[] RijndaelEncrypt(byte[] clearData, byte[] Key) { var memoryStream = new MemoryStream(); Rijndael algorithm = Rijndael.Create(); algorithm.Key = Key; algorithm.IV = InitializationVector; var criptoStream = new CryptoStream(memoryStream, algorithm.CreateEncryptor(), CryptoStreamMode.Write); criptoStream.Write(clearData, 0, clearData.Length); criptoStream.Close(); byte[] encryptedData = memoryStream.ToArray(); return encryptedData; } private byte[] RijndaelDecrypt(byte[] cipherData, byte[] Key) { var memoryStream = new MemoryStream(); Rijndael algorithm = Rijndael.Create(); algorithm.Key = Key; algorithm.IV = InitializationVector; var criptoStream = new CryptoStream(memoryStream, algorithm.CreateDecryptor(), CryptoStreamMode.Write); criptoStream.Write(cipherData, 0, cipherData.Length); criptoStream.Close(); byte[] decryptedData = memoryStream.ToArray(); return decryptedData; } This is the SQL Code sample: open symmetric key columnKey decryption by password = N'{pwd!!i_ll_not_show_it_here}' declare @enc varchar(max) set @enc = dbo.VarBinarytoBase64(EncryptByKey(Key_GUID('columnKey'), 'blablabla')) select LEN(@enc), @enc This varbinaryToBase64 is a tested sql function we use to convert varbinary to the same format we use to store strings in the .net application. The result in C# is: eg0wgTeR3noWYgvdmpzTKijkdtTsdvnvKzh+uhyN3Lo= The same result in SQL2k8 is: AI0zI7D77EmqgTQrdgMBHAEAAACyACXb+P3HvctA0yBduAuwPS4Ah3AB4Dbdj2KBGC1Dk4b8GEbtXs5fINzvusp8FRBknF15Br2xI1CqP0Qb/M4w I just didn't get yet what I'm doing wrong. Do you have any ideas? EDIT: One point I think is crucial: I have one Initialization Vector at my C# code, 16 bytes. This IV is not set at SQL symmetric key, could I do this? But even not filling the IV in C#, I get very different results, both in content and length.

  • How to change the assemblyIdentity of an executable

    - by David
    I want to hide the tool I used to create an .exe file. I am not doing anything illegal, I just want to protect my intellectual property from being copied. If I open the exe file in a text editor I see the following section. <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="XXX.XX" processorArchitecture="X86" name="Microsoft.Windows.NameOfTheTool" type="win32" /> </assembly> I have attempted to change the name to: name="Microsoft.Windows.SomeOtherName" This resulted in the following message when I attempted to execute the file. "This application has failed to start because its side-by-side configuration is incorrect." How can I solve this?

  • java get file paths

    - by user283188
    hey everybody, I have a jsp page which contains the code which prints all files in a given directory and their file paths. The code is if (dir.isDirectory()) { File[] dirs = dir.listFiles(); for (File f : dirs) { if (f.isDirectory() && !f.isHidden()) { File files[] = f.listFiles(); for (File d : files) { if (d.isFile() && !d.isHidden()) { System.out.println(d.getName()+ d.getParent() + (d.length()/1024)); } } } if (f.isFile() && !f.isHidden()) { System.out.println(f.getName()+ f.getParent() + (f.length()/1024)); } } } The problem is that it prints the complete file path, which when accessed from tomcat is invalid. For example, the code spits out the following path: /usr/local/tomcat/sites/web_tech/images/scores/blah.jpg and I want it to only print the path up to /images ie /images/scores/blah.jpg I know I could just mess around with an actual string, ie splitting it or string matching, but is there an easier way to do it? Thanks

  • Most efficient way to save tile data of an isometric game

    - by Harmen
    Hello, I'm working on an isometric game for fast browsers that support <canvas>, which is great fun. To save information of each tile, I use a two-dimensional array which contains numbers representing a tile ID, like: var level = [[1, 1, 1, 2, 1, 0], [0, 1, 1, 2, 0, 1], [0, 1, 1, 2, 1, 1]]; var tiles = [ {name: 'grass', color: 'green'}, {name: 'water', color: 'blue'}, {name: 'forest', color: 'ForestGreen'} ]; So far it works great, but now I want to work with heights and slopes like in this picture: For each tile I need to save it's tile ID, height and information about which corners are turned upward. I came up with a simple idea about a bitwise representation of all four corners, like this: 1011 // top, bottom and left corner turned up My question is: what is the most efficient way to save these three values for each cell? Is it possible to save these three values as one integer?

  • Lua class instance with nested tables

    - by Anonnobody
    Hello, Simple lua game with simple class like so: creature = class({ name = "MONSTER BADDY!", stats = { power = 10, agility = 10, endurance = 10, filters = {} }, other_things = ... }) creatureA = creature.new() creatureB = creature.new() creatureA.name = "Frank" creatureB.name = "Zappa" creatureA.stats.agility = 20 creatureB.stats.power = 12 -- blah blah blah Non table values are individual to each instance, but table values are shared among all instances and if I modify a stats.X value in one instance, all other instances see the same stats table. Q1: Is my OO implementation flawed? I tried LOOP and the same result occured, is there a fundamental flaw in my logic? Q2: How would you have each instance of creature have it's own stats table (and sub tables)? PS. I cannot flatten my class table as it's a bit more complicated than the example and other parts of the code are simplified with this nested table implementation. Thanks a bunch.

  • NSLinguisticTagger on the contents of an NSTextStorage- crashing bug

    - by Remy Porter
    I'm trying to use an NSLinguisticTagger to monitor the contents of an NSTextStorage and provide some contextual information based on what the user types. To that end, I have an OverlayManager object, which wires up this relationship: -(void) setView:(NSTextView*) view { _view = view; _layout = view.layoutManager; _storage = view.layoutManager.textStorage; //get the TextStorage from the view [_tagger setString:_storage.string]; //pull the string out, this grabs the mutable version [self registerForNotificationsOn:self->_storage]; //subscribe to the willProcessEditing notification } When an edit occurs, I make sure to trap it and notify the tagger (and yes, I know I'm being annoyingly inconsistent with member access, I'm rusty on Obj-C, I'll fix it later): - (void) textStorageWillProcessEditing:(NSNotification*) notification{ if ([self->_storage editedMask] & NSTextStorageEditedCharacters) { NSRange editedRange = [self->_storage editedRange]; NSUInteger delta = [self->_storage changeInLength]; [_tagger stringEditedInRange:editedRange changeInLength:delta]; //should notify the tagger of the changes [self highlightEdits:self]; } } The highlightEdits message delegates the job out to a pool of "Overlay" objects. Each contains a block of code similar to this: [tagger enumerateTagsInRange:range scheme:NSLinguisticTagSchemeLexicalClass options:0 usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) { if (tag == PartOfSpeech) { [self applyHighlightToRange:tokenRange onStorage:storage]; } }]; And that's where the problem is- the enumerateTagsInRange method crashes out with a message: 2014-06-04 10:07:19.692 WritersEditor[40191:303] NSMutableRLEArray replaceObjectsInRange:withObject:length:: Out of bounds This problem doesn't occur if I don't link to the mutable copy of the underlying string and instead do a [[_storage string] copy], but obviously I don't want to copy the entire backing store every time I want to do tagging. This all should be happening in the main run loop, so I don't think this is a threading issue. The NSRange I'm enumerating tags on exists both in the NSTextStorage and in the NSLinguisticTagger's view of the string. It's not even the fact that the applyHighlightToRange call adds attributes to the string, because it crashes before even reaching that line. I attempted to build a test case around the problem, but can't replicate it in those situations: - (void) testEdit { NSAttributedString* str = [[NSMutableAttributedString alloc] initWithString:@"Quickly, this is a test."]; text = [[NSTextStorage alloc] initWithAttributedString:str]; NSArray* schemes = [NSLinguisticTagger availableTagSchemesForLanguage:@"en"]; tagger = [[NSLinguisticTagger alloc] initWithTagSchemes:schemes options:0]; [tagger setString:[text string]]; [text beginEditing]; [[text mutableString] appendString:@"T"]; NSRange edited = [text editedRange]; NSUInteger length = [text changeInLength]; [text endEditing]; [tagger stringEditedInRange:edited changeInLength:length]; [tagger enumerateTagsInRange:edited scheme:NSLinguisticTagSchemeLexicalClass options:0 usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) { //doesn't matter, this should crash }]; } That code doesn't crash.

  • Ruby Built In Method to Create Multidimensional Array From Single Dimensioned Array

    - by Ell
    If I have an array like this: [0, 1, 2, 3, 4, 5], is there a built in method to create this: [[0, 1, 2], [3, 4, 5]] given a width of 3? If there is no built in method, how could I improve on this? def multi_to_single(array, width) return [].tap{|md_array| (array.length.to_f / width).ceil.times {|y| row = (array[(y*width), width]) md_array.push( row + Array.new(width - row.length)) } } end I feel like I have missed something obvious because I haven't programmed ruby in a while! Thanks in advance, ell. EDIT: It needs to be in the core library, so no ruby on rails or anything.

  • Background-image won't change using jquery in IE6

    - by slav
    There is a panel on my page with no default background-image css. On load it is set with jquery to an initial image, waits for 10 seconds then loads a random image out of some predetermined images. There are previous and next buttons which allow you to cycle through the images. In ie6 the initial image loads and then a random image also loads after 10 seconds, however pressing prev/next causes the background to become white and the images aren't loaded. With alerts I was able to find that it's still keeping track of the position and url of the image it's supposed to load, but just won't load it. Here is the code below. <script type="text/javascript"> var facts = new Array(); var position; $(document).ready(function() { <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/../node[@nodeName='Fun Fact Folder']/node"> facts[<xsl:value-of select="position()" />] = '<xsl:value-of select="." />'; </xsl:for-each> if(window.location.pathname == "/homepage.aspx" || window.location.pathname == "/") { $(".fun_facts_bg").css("background-image", "url(images/fun_fact_homepage.JPG)"); setTimeout("randomFact()",10000); } else { randomFact(); } }); function randomFact() { $("a.previous_button").css("display", "block"); $("a.next_button").css("display", "block"); position = Math.ceil(Math.random() * (facts.length - 1)); changeFact(0); } function changeFact(increment) { position = checkPosition(position, increment); $(".fun_facts_bg").css("background-image", "url(" + facts[position] + ")"); } <xsl:text disable-output-escaping="yes">&lt;!--//--&gt;&lt;![CDATA[//&gt;&lt;!-- function checkPosition(currentPos, increment) { currentPos = currentPos + increment; if (currentPos &gt; facts.length - 1) { currentPos = 1; } else if (currentPos &lt; 1) { currentPos = facts.length - 1; } return currentPos; } //--&gt;&lt;!]]&gt;</xsl:text> </script> <a class="previous_button" href="javascript:void(0);" onclick="changeFact(-1);"> <a class="next_button" href="javascript:void(0);" onclick="changeFact(1);">

  • Strange behavior of move with strings

    - by Umair Ahmed
    I am testing some enhanced string related functions with which I am trying to use move as a way to copy strings around for faster, more efficient use without delving into pointers. While testing a function for making a delimited string from a TStringList, I encountered a strange issue. The compiler referenced the bytes contained through the index when it was empty and when a string was added to it through move, index referenced the characters contained. Here is a small downsized barebone code sample:- unit UI; interface uses System.SysUtils, System.Types, System.UITypes, System.Rtti, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.Layouts, FMX.Memo; type TForm1 = class(TForm) Results: TMemo; procedure FormCreate(Sender: TObject); end; var Form1: TForm1; implementation {$R *.fmx} function StringListToDelimitedString ( const AStringList: TStringList; const ADelimiter: String ): String; var Str : String; Temp1 : NativeInt; Temp2 : NativeInt; DelimiterSize : Byte; begin Result := ' '; Temp1 := 0; DelimiterSize := Length ( ADelimiter ) * 2; for Str in AStringList do Temp1 := Temp1 + Length ( Str ); SetLength ( Result, Temp1 ); Temp1 := 1; for Str in AStringList do begin Temp2 := Length ( Str ) * 2; // Here Index references bytes in Result Move ( Str [1], Result [Temp1], Temp2 ); // From here the index seems to address characters instead of bytes in Result Temp1 := Temp1 + Temp2; Move ( ADelimiter [1], Result [Temp1], DelimiterSize ); Temp1 := Temp1 + DelimiterSize; end; end; procedure TForm1.FormCreate(Sender: TObject); var StrList : TStringList; Str : String; begin // Test 1 : StringListToDelimitedString StrList := TStringList.Create; Str := ''; StrList.Add ( 'Hello1' ); StrList.Add ( 'Hello2' ); StrList.Add ( 'Hello3' ); StrList.Add ( 'Hello4' ); Str := StringListToDelimitedString ( StrList, ';' ); Results.Lines.Add ( Str ); StrList.Free; end; end. Please devise a solution and if possible, some explanation. Alternatives are welcome too.

  • Combining Two Models in Rails for a Form

    - by matsko
    Hey Guys. I'm very new with rails and I've been building a CMS application backend. All is going well, but I would like to know if this is possible? Basically I have two models: @page { id, name, number } @extended_page { id, page_id, description, image } The idea is that there are bunch of pages but NOT ALL pages have extended_content. In the event that there is a page with extended content then I want to be able to have a form that allows for editing both of them. In the controller: @page = Page.find(params[:id]) @extended= Extended.find(:first, :conditions = ["page_id = ?",@page.id]) @combined = ... #merge the two somehow So in the view: <%- form_for @combined do |f| % <%= f.label :name % <%= f.text_field :name % ... <%= f.label :description % <%= f.text_field :description % <%- end This way in the controller, there only has to be one model that will be updated (which will update to both). Is this possible?

  • Retrieve names by ratio of their occurance

    - by jjiffer
    Hello, I'm somewhat new to SQL queries, and I'm struggling with this particular problem. Let's say I have query that returns the following 3 records (kept to one column for simplicity): Tom Jack Tom And I want to have those results grouped by the name and also include the fraction (ratio) of the occurrence of that name out of the total records returned. So, the desired result would be (as two columns): Tom | 2/3 Jack | 1/3 How would I go about it? Determining the numerator is pretty easy (I can just use COUNT() and GROUP BY name), but I'm having trouble translating that into a ratio out of the total rows returned. Any help is much appreciated!

  • MVC validation error with strongly typed view

    - by Remnant
    I have a simple form that I would like to validate on form submission. Note I have stripped out the html for ease of viewing <%=Html.TextBox("LastName", "")%> //Lastname entry <%=Html.ValidationMessage("LastName")%> <%=Html.TextBox("FirstName", "")%>//Firstname entry <%=Html.ValidationMessage("FirstName")%> <%=Html.DropDownList("JobRole", Model.JobRoleList)%> //Dropdownlist of job roles <% foreach (var record in Model.Courses) // Checkboxes of different courses for user to select { %> <li><label><input type="checkbox" name="Courses" value="<%=record.CourseName%>" /><%= record.CourseName%></label></li> <% } %> On submission of this form I would like to check that both FirstName and LastName are populated (i.e. non-zero length). In my controller I have: public ActionResult Submit(string FirstName, string LastName) { if (FirstName.Trim().Length == 0) ModelState.AddModelError("FirstName", "You must enter a first name"); if (LastName.Trim().Length == 0) ModelState.AddModelError("LastName", "You must enter a first name"); if (ModelState.IsValid) { //Update database + redirect to action } return View(); //If ModelState not valid, return to View and show error messages } Unfortunately, this code logic produces an error that states that no objects are found for JobRole and Courses. If I remove the dropdownlist and checkboxes then all works fine. The issue appears to be that when I return the View the view is expecting objects for the dropwdownlist and checkboxes (which is sensible as that is what is in my View code) How can I overcome this problem? Things I have considered: In my controller I could create a JobRoleList object and Course object to pass to the View so that it has the objects to render. The issue with this is that it will overwrite any dropdownlist / checkbox selections that the user has already made. In the parameters of my controller method Submit I could aslo capture the JobRoleList object and Course object to pass back to the View. Again, not sure this would capture any items the user has already selected. I have done much googling and reading but I cannot find a good answer. When I look at examples in books or online (e.g. Nerddinner) all the validation examples involve simple forms with TextBox inputs and don't seems to show instances with multiple checkboxes and dropdownlists. Have I missed something obvious here? What would be best practice in this situation? Thanks

  • How to have multiple tables with multiple joins

    - by williamsdb
    I have three tables that I need to join together and get a combination of results. I have tried using left/right joins but they don't give the desired results. For example: Table 1 - STAFF id name 1 John 2 Fred Table 2 - STAFFMOBILERIGHTS id staffid mobilerightsid rights --this table is empty-- Table 3 - MOBILERIGHTS id rightname 1 Login 2 View and what I need is this as the result... id name id staffid mobilerightsid rights id rightname 1 John null null null null 1 login 1 John null null null null 2 View 2 Fred null null null null 1 login 2 Fred null null null null 2 View I have tried the following : SELECT * FROM STAFFMOBILERIGHTS SMR RIGHT JOIN STAFF STA ON STA.STAFFID = SMR.STAFFID RIGHT JOIN MOBILERIGHTS MRI ON MRI.ID = SMR.MOBILERIGHTSID But this only returns two rows as follows: id name id staffid mobilerightsid rights id rightname null null null null null null 1 login null null null null null null 2 View Can what I am trying to achieve be done and if so how? Thanks

  • Phonegap/Cordova orientation change Android 4

    - by user1477576
    I have a problem changing the orientation of the device (Android 4). In other versions it works fine. Versión of Cordova: cordova-1.8.0.js / cordova-1.8.1.js In Android 4 the app crash or show: "A network error occurred. (file:///android_asset/www/index.html)" I searched a lot about this and no answer solves the problem. In most cases users suggest adding: android:configChanges="orientation|keyboardHidden|screenSize" In other cases: super.setIntegerProperty("loadUrlTimeoutValue",60000); That not work for me :( My manifest activity: <activity android:name=".AppNameActivity" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden|screenSize"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> The application should run on Android 2.2 to 4. Thank you very much for the help.
