How to debug browser crash when running Silverlight app

- by onedozenbagels

I am on a team of three people who are developing a Silverlight application. On two of our developers' machines the app seems to randomly crash. It never crashes on the third developer's machine. The nature of the crash is that internet explorer just dies with an "Internet Explorer has stopped working" message. The problem details look like this: Problem Event Name: BEX Application Name: IEXPLORE.EXE Application Version: 8.0.6001.18882 Application Timestamp: 4b3ed243 Fault Module Name: StackHash_2cd8 Fault Module Version: 0.0.0.0 Fault Module Timestamp: 00000000 Exception Offset: 0024df00 Exception Code: c0000005 Exception Data: 00000008 OS Version: 6.0.6002.2.2.0.256.6 Locale ID: 1033 Additional Information 1: 2cd8 Additional Information 2: 0c337fa6c2057a9dbce1860c5e2d8315 Additional Information 3: e13b Additional Information 4: 5da012709e52526a1af19795dc4a33fd Then windows displays this message: "To help protect your computer, Data Execution Prevention has closed Internet Explorer." If I am attached to the app with the Visual Studio debugger the only information I get is this line in the output window: "The program '[2140] iexplore.exe: Silverlight' has exited with code -1073741819 (0xc0000005)." How should I go about debugging this problem? I'm not really sure where to start.

desktop shortcut icon not showing in web setup project

- by davsan

i've created a web setup project and i wanted it to create a desktop shortcut to the web application (ex: http://localhost/xx/yy.aspx). up to this point it was pretty easy: i created a shortcut (doesnt matter where), gave it the url i wanted, added this to the User's Desktop special folder of my web setup project, and it was placed on the desktop after the installation. but then i wanted to display my custom shortcut icon. i set the icon of the shortcut i've created on my file system. then i re-included this to the setup project. however after the installation the shortcut kept showing the default IE icon again. (i tried these on windows 2003 server, on win xp the shortcut showed up iconless) after some trials i found another way: i recreated an iconless shortcut on my file system, opened my web setup project, included this shortcut and my icon to Web Application Folder under File System on Target Machine, then clicked on User's Desktop, right clicked on the right hand side blank area, selected Create New Shortcut and chose the shortcut i've just added. Then under User's Desktop i clicked on the newly created shortcut, opened the Properties window and set its Icon property to my included icon. These steps solved it all both on 2003 server and win xp. Though this wasnt really a question i wanted to share it anyways because it was quite annoying.

JSF Render response programmatically

- by Shamik

I have one parent page with a parentManagedBean (attached to Session Scope). On click of a button on this parent page, one popup comes which has a childManagedBean (attached to Request scope). Now ChildManagedBean holds a reference to parentManaged bean through JSF's managed property facility. On this popup window, user selects some option which populates a large value object. I use the managed property of childManagedBean to set the values from this large object to that of parentManagedBean. Problem is - The parent page shows a link, on click of which a popup comes, on selection of the popup, the popup disappears and set the values to the parentManaged bean. So far so good, but the newly set values need to appear on the parent page. This is where I am stuck. How to programmatically render the master page/render page when I am at the child managed bean? Is there a way I can get handle of the parent page and refresh it? Note: I'm using JSF 1.1 EDIT- After following the solution of "resubmit-ing the form" from javascript, I am seeing that the old form is getting resubmitting which overwrites all of my changed values.

o3d javascript uncaught reference error

- by David Menard

hey, im new to javascript and am intersted in creating a small o3d script: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Test Game Website</title> </head> <body> <script type="text/javascript" src="o3djs/base.js"></script> <script type = "text/javascript" id="myscript"> o3djs.require('o3djs.camera'); window.onload = init; function init(){ document.write("jkjewfjnwle"); } </script> <div align="background"> <div id="game_container" style="margin: 0px auto; clear: both; background-image: url('./tmp.png'); width: 800px; height:600px; padding: 0px; background-repeat: no-repeat; padding-top: 1px;"></div> </div> </body> </html> the browser cant seem to find o3djs/base.js in this line <script type="text/javascript" src="o3djs/base.js"></script> and gives me an uncaught referenceerror at this line o3djs.require('o3djs.camera'); Obviously, because it can't find the o3djs/base.js... I have installed the o3d pluggin from google and they say that should be IT ive tried on firefox, ie and chrome thanks

Need to kill a session?

- by rob - not a robber

Really quick here... I think I have the answer, but just looking for some validation. I have a site with two "points of entry." One is for a standard user and one is for an admin account. In the real world, an admin could have a standard user account and try to login as an admin while already being under the standard user session. I have two separate front ends to facilitate login. The normal user one is frilly and has ads and the like, the admin one is strictly business, so any suggestion to have the two user types login through the same "door" is not on the table. Would you advise on the admin login page to destroy any active sessions? Once the admin is in, they'll only be tooling around in their admin area and not on the main site. Has anyone run into probs using this method and having an admin-type user try to log back in in a new window as a "user" to view changes from a logged in user's prespective? Thanks in advance. So many cans of worms :)

javascript class calling XMLHttpRequest internally, then handling onreadystatechange

- by Radu M

this thing almost works: function myClass(url) { this.source = url; this.rq = null; this.someOtherProperty = "hello"; // open connection to the ajax server this.start = function() { if (window.XMLHttpRequest) { this.rq = new XMLHttpRequest(); if (this.rq.overrideMimeType) this.rq.overrideMimeType("text/xml"); } else this.rq = new ActiveXObject("Microsoft.XMLHTTP"); try { this.rq.onreadystatechange = connectionEvent; this.rq.open("GET", this.source, true); this.rq.send(null); this.state = 1; } catch (err) { // some error handler here } } function connectionEvent() { alert("i'm here"); alert("this doesnt work: " + this.someOtherProperty); } } // myClass so it's nothing more than having the XMLHttpRequest object as a member of my class, instead of globally defined, and invoking it in the traditional way. however, inside my connectionEvent callback function, the meaning of "this" is lost, even though the function itself is scoped inside myClass. i also made sure that the object that i instantiate from myClass is kept alive long enough (declared global in the script). in all the examples of using javascript classes that i saw, "this" was still available inside the inner functions. for me, it is not, even if i take my function outside and make it a myClass.prototype.connectionEvent. what am i doing wrong? thank you.

iPhone UI addSubview causing concurrency exception

- by Eli

This is really odd... I run my app, and while it is opening and the views are constructing I get: Collection <CALayerArray: 0x124650> was mutated while being enumerated. The code trace goes through the following: main UIApplicationMain -[UIApplication _run] CFRunLoopRunInMode CFRunLoopRunSpecific _UIApplicationHandleEvent -[UIApplication sendEvent:] -[UIApplication handleEvent:withNewEvent:] -[UIApplication _runWithURL:sourceBundleID:] -[UIApplication _performInitilizationWithURL:sourceBundleID:] -[AppDelegate applicationDidFinishLaunching:] +[Controller initializeController] //This is my own function [window addSubview: pauseMenuController.view] //This is the last point of my code it goes through -[UIView(Hierarchy) addSubview:] -[UIView(Internal) _addSubview:positioned:relativeTo:] -[UIView(Hierarchy) _makeSubtreePerformSelector:withObject:] -[UIView(Hierarchy) _makeSubtreePerformSelector:withObject:withObject:copySublayers:] -[UIView(Hierarchy) _makeSubtreePerformSelector:withObject:withObject:copySublayers:] _NSFastEnumerationMutationHandler objc_exception_throw I've run the game lots and lots and lots of times and I've never seen this, then suddenly it popped up. The weird thing is that I'm not creating any other threads (that I know of) until after this code all gets called. It'll be easier for me to debug this if someone can give me some explanation of what might be getting modified while it's being accessed in a UIView. Does it have something to do with adding something to the view while it's already adding something, maybe? Any ideas?

Synchronize DataGrid and DataForm in Silverlight 3

- by SpiralGray

I've been banging my head against the wall for a couple of days on this and it's time to ask for help. I've got a DataGrid and DataForm on the same UserControl. I'm using an MVVM approach so there is a single ViewModel for the UserControl. That ViewModel has a couple of properties that are relevant to this discussion: public ObservableCollection<VehicleViewModel> Vehicles { get; private set; } public VehicleViewModel SelectedVehicle { get { return selectedVehicle; } private set { selectedVehicle = value; OnPropertyChanged( "SelectedVehicle" ); } } In the XAML I've got the DataGrid and DataForm defined as follows: <data:DataGrid SelectionMode="Single" ItemsSource="{Binding Vehicles}" SelectedItem="{Binding SelectedVehicle, Mode=TwoWay}" AutoGenerateColumns="False" IsReadOnly="True"> <dataFormToolkit:DataForm CurrentItem="{Binding SelectedVehicle}" /> So as the SelectedItem changes on the DataGrid it should push that change back to the ViewModel and when the ViewModel raises the OnPropertyChanged the DataForm should refresh itself with the information for the newly-selected VehicleViewModel. However, the setter for SelectedVehicle is never being called and in the Output window of VS I'm seeing the following error: System.Windows.Data Error: ConvertBack cannot convert value 'xxxx.ViewModel.VehicleViewModel' (type 'xxxx.ViewModel.VehicleViewModel'). BindingExpression: Path='SelectedVehicle' DataItem='xxxx.ViewModel.MainViewModel' (HashCode=31664161); target element is 'System.Windows.Controls.DataGrid' (Name=''); target property is 'SelectedItem' (type 'System.Object').. System.MethodAccessException: xxxx.ViewModel.MainViewModel.set_SelectedVehicle(xxxx.ViewModel.VehicleViewModel) It sounds like it's having a problem converting from a VehicleViewModel to an object (or back again), but I'm confused as to why that would be (or even if I'm on the right track with that assumption). Each row/item in the DataGrid should be a VehicleViewModel (because the ItemsSource is bound to an ObservableCollection of that type), so when the SelectedItem changes it should be dealing with an instance of VehicleViewModel. Any insight would be appreciated.

Bubble Breaker Game Solver better than greedy?

- by Gregory

For a mental exercise I decided to try and solve the bubble breaker game found on many cell phones as well as an example here:Bubble Break Game The random (N,M,C) board consists N rows x M columns with C colors The goal is to get the highest score by picking the sequence of bubble groups that ultimately leads to the highest score A bubble group is 2 or more bubbles of the same color that are adjacent to each other in either x or y direction. Diagonals do not count When a group is picked, the bubbles disappear, any holes are filled with bubbles from above first, ie shift down, then any holes are filled by shifting right A bubble group score = n * (n - 1) where n is the number of bubbles in the bubble group The first algorithm is a simple exhaustive recursive algorithm which explores going through the board row by row and column by column picking bubble groups. Once the bubble group is picked, we create a new board and try to solve that board, recursively descending down Some of the ideas I am using include normalized memoization. Once a board is solved we store the board and the best score in a memoization table. I create a prototype in python which shows a (2,15,5) board takes 8859 boards to solve in about 3 seconds. A (3,15,5) board takes 12,384,726 boards in 50 minutes on a server. The solver rate is ~3k-4k boards/sec and gradually decreases as the memoization search takes longer. Memoization table grows to 5,692,482 boards, and hits 6,713,566 times. What other approaches could yield high scores besides the exhaustive search? I don't seen any obvious way to divide and conquer. But trending towards larger and larger bubbles groups seems to be one approach Thanks to David Locke for posting the paper link which talks above a window solver which uses a constant-depth lookahead heuristic.

javascript addEventListener onStateChange not working in IE

- by user347456

Hi, I have two colorbox popup boxes which show a youtube video in each. When they're finished playing, I'm trying to have them automatically close the colorbox window. This code below works perfect in firefox, but in IE I can't get addEventListener to work. I've tried attachEvent with no success. Can anybody offer any suggestions as to how to solve this? It seems simple but I'm exhausted trying to find a solution. By the way, this is my first time as stackoverflow and it's very impressive. var params = { allowScriptAccess: "always" }; var atts = { id: "ytplayer1" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO1&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo1", "popupVideoContainer1", "640", "385", "8", null, null, params, atts); var params2 = { allowScriptAccess: "always" }; var atts2 = { id: "ytplayer2" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO2&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo2", "popupVideoContainer2", "640", "385", "8", null, null, params2, atts2); function onYouTubePlayerReady(playerId) { if(playerId == 'ytvideo1'){ var ytplayer = document.getElementById('ytplayer1'); ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if(playerId == 'ytvideo2'){ var ytplayer = document.getElementById("ytplayer2"); //ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); if (ytplayer.addEventListener) { ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if (ytplayer.attachEvent) { ytplayer.attachEvent("onStateChange", onytplayerStateChange); } } } function onytplayerStateChange(newState) { if(newState == 0){ $.fn.colorbox.close(); } }

Ajax.BeginForm driving me crazy

- by Fabio Milheiro

ASP.NET MVC3 I have a partial view that is initially rendered inside a div. The following is the partial code: @model Venue.Models.Validation.CustomerRequestModel <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> <script type="text/javascript" src="/Scripts/MicrosoftAjax.js"></script> <script type="text/javascript" src="/Scripts/MicrosoftMvcAjax.js"></script> <script type="text/javascript" src="/Scripts/MicrosoftMvcValidation.js"></script> @{ Html.RenderPartial("Message"); } @Html.ValidationSummary() @using (Ajax.BeginForm( "Customer", "Service", null, new AjaxOptions() { HttpMethod = "post", InsertionMode = InsertionMode.Replace, LoadingElementDuration = 100, LoadingElementId = "loading-customer", OnBegin = "hideSubmitButton", OnSuccess = "hideForm", OnComplete = "showSubmitButton", OnFailure = "showErrorMessage", UpdateTargetId = "formclientes", }, new { id = "customer-form" })) { // Fields are all type="text" although some are numbers. <input type="text" name="Address" class="clientes_form" /> } The action: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Customer(CustomerRequestModel customer) { // ... } In the immediate window, this is what I get: this.Request.IsAjaxRequest() false Why?!

facebook connect button not producing pop-up

- by bigmac

This is a really simple question, but I can't seem to find the answer. I am just getting started with Facebook Connect. I would like to use it only for user authentication, so there is no need for my users to create another account. I used a very basic example from wiki.developers.facebook.com : <html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"> <head></head> <body> <fb:login-button></fb:login-button> <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php/en_US" type="text/javascript"></script> <script type="text/javascript"> FB.init("***api-key***", "xd_receiver.htm"); </script> </body> </html> Very straight forward. It seems to work fine. However, if I am currently already logged in to Facebook, the pop-up window doesn't come up when I click the login button. Why is that?

Hudson plugin, Java error "... disagree on InnerClasses attribute"

- by StackedCrooked

I am trying to be able to step through the code of a Hudson plugin called SVNPublisher. I checked out the code for SVNPublisher, used Netbeans to open the project, and clicked "Debug Main project". This results in a Firefox window opening address http://localhost:8080 which shows the Hudson main page. Clicking the "New Job" link results in an error page: HTTP ERROR: 500 jar:file:/home/francis/svn/svnpublisher/target/work/webapp/WEB-INF/lib/hudson-core-1.319.jar!/lib/hudson/newFromList/form.jelly:43:47: <j:forEach> hudson.scm.SubversionTagAction and hudson.scm.SubversionTagAction$DescriptorImpl disagree on InnerClasses attribute RequestURI=/newJob Caused by: org.apache.commons.jelly.JellyTagException: jar:file:/home/francis/svn/svnpublisher/target/work/webapp/WEB-INF/lib/hudson-core-1.319.jar!/lib/hudson/newFromList/form.jelly:43:47: hudson.scm.SubversionTagAction and hudson.scm.SubversionTagAction$DescriptorImpl disagree on InnerClasses attribute at org.apache.commons.jelly.impl.TagScript.handleException(TagScript.java:713) at org.apache.commons.jelly.impl.TagScript.run(TagScript.java:282) at org.apache.commons.jelly.impl.ScriptBlock.run(ScriptBlock.java:95) ...

Windows could not start the Apache2 on Local Computer - problem

During the installation of Apache2 I got the following message into cmd window: Installing the Apache2.2 service The Apache2.2 service is successfully installed. Testing httpd.conf.... Errors reported here must be corrected before the service can be started. httpd.exe: Could not reliably determine the server's fully qualified domain name , using 192.168.1.3 for ServerName (OS 10048)Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs Note the errors or messages above, and press the key to exit. 24... and after installing everything look fine, but it isn't. If I try to start service I got the following message: Windows could not start the Apache2 on Local Computer. For more information, review the System Event Log. If this is a non-Micorsoft service, contact the service vendor, and refer to service-specific error code 1. Apach2 version is 2.2.9 Does anyone have the same problem, or could help me.

Thumbnail Provider not working

- by Dan

I'm trying to write a Windows Explorer thumbnail handler for our custom file type. I've got this working fine for the preview pane, but am having trouble getting it to work for the thumbnails. Windows doesn't even seem to be trying to call the DllGetClassObject entry point. Before I continue, note that I'm using Windows 7 and unmanaged C++. I've registered the following values in the registry: HKCR\CLSID\<my guid> HKCR\CLSID\<my guid>\InprocServer32 (default value being path to my DLL) HKCR\CLSID\<my guid>\InprocServer32\ThreadingModel (value = "Apartment") HKCR\.<my ext>\shellex\{E357FCCD-A995-4576-B01F-234630154E96} (value = my guid) I've also tried using the Win SDK sample, and that doesn't work. And also the sample project in this article (http://www.codemonkeycodes.com/2010/01/11/ithumbnailprovider-re-visited/), and that doesn't work. I'm new to shell programming, so not really sure the best way of debugging this. I've tried attaching the debugger to explorer.exe, but that doesn't seem to work (breakpoints get disabled, and none of my OutputDebugStrings get displayed in the output window). Note that I tried setting the "DesktopProcess" in the registry as described in the WinSDK docs for debugging the shell, but I'm still only seeing one explorer.exe in the task manager - so that "may" be why I can't debug it?? Any help with this would be greatly appreciated! Regards, Dan.

Extremely slow MFMailComposeViewControllerDelegate

- by Jeff B

I have a bit of a strange problem. I am trying to send in-app email. I am also using Cocos2d. It works, so far as I get the mail window and I can send mail, but it is extremely slow. It seems to only accept touches every second or so. I checked the cpu usage, and it is quite low. I paused my director, so nothing else should be happening. Any ideas? I am pulling my hair out. I looked at some examples and did the following: Made my scene the mail delegate: @interface MyLayer : CCLayer <MFMailComposeViewControllerDelegate> { ... } And implemented the following function in the scenes: -(void) showEmailWindow: (id) sender { [[CCDirector sharedDirector] pause]; MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [picker setSubject: @"My subject here"]; NSString *emailBody = @"<h1>Here is my email!</h1>"; [picker setMessageBody:emailBody isHTML:YES]; [myMail presentModalViewController:picker animated:NO]; [picker release]; } I also implemented the mailComposeController, to handle the callback.

Modified jQuery innerfade sluggish

- by Jay Hankins

HI. I am using the jQuery innerfade plugin to scroll through some images on my site. Innerfade is sluggish to move on Firefox 3.6.3, and IE 8. IE 8 is much worse than Firefox, and Chrome runs smoothly. Can you analyze my code to see what the problem is? I've used the modified innerfade from here: http://www.stylephp.com/2009/01/17/customizing-jquery-innerfade-plug-in-adding-controls-navigation-and-caption/ My sites are here: Without bg image: http://dl.dropbox.com/u/145908/doozie2/index.html With bg image: http://dl.dropbox.com/u/145908/doozie2/index2.html Removing my background image fixes the situation; it's not that big of a file. I don't understand why that is an issue. I am using a technique to resize the image to fit the browser window, as you can see in the CSS. Thanks so much. P.S. Sorry, I'm a new user so I can't post more than one link. Please copy and paste the address between <.

Debugging MinGW program with gdb on Windows, not terminating at assert failure

Help with editing data in entity framework.

- by Levelbit

Title of this question is simple because there is no an easy explanation for what I'm trying to ask you. I hope you'll understand in the end :). I have to tables in my database: Company and Location (relationship:one to many) and corresponding entity sets. In my wpf application I have some datagrid which I want to fill with locations and to be able to edit every row in separate window as some form of details view (so I don't want to edit my data in datagrid). I did this by accessing Location entity from selected row and creating a new Location entity and then I copy properties from original entity to newly created. Something like cloning the object. After editing if I press OK changed data is copied to original object back, and if I press Cancel nothing happens. Of course, you probably thinking I could use NoTracking option and AttachAsModified method as was mentioned as solution in some earlier questions(see:http://stackoverflow.com/questions/803022/changing-entities-in-the-entityframework) by Alex James, but lets say I had some problems about that and I have my own reasons for doing this. Finally, because navigation property(Company) of my location entity is assigned to newly created location object(during cloning) from some reason in object context additional object as copy of object I want to edit from datagrid is created without my will(similar problem :http://blogs.msdn.com/alexj/archive/2009/12/02/tip-47-how-fix-up-can-make-it-hard-to-change-relationships.aspx). So, when I do ObjectContext.SaveChanges it inserts additional row of data into my database table Location, the same as the one i wanted to edit. I read about sth like this, but I don't quite understand why is that and how to block or override this. I hope I was clear as I could. Please, solutions or some other ideas.

Can anyone tell me about a jQuery modal dialog box library that doesn't suck

- by Ritesh M Nayak

jQuery based modal dialog boxes are great as long as you do as much as the example tells you to. I need a jQuery based modal dialog box library that has to have the following characteristics: It should be fast, something like the add and link dialog on StackOverflow. Most libraries take an eternity to load the dialog with its fancy effects and stuff. I want to call it using a script. Show a hidden div or a span element inline. MOst of the libraries talk filling an anchor with rel, class and href=#hiddenDiv sort of things. I need to be able to what I want without adding unnecessary attributes to my anchor. Something like this function showDialog(values) { processToChangeDom(values); changeDivTobeDisplayed(); modalDialog.show(); } It should reflect changes I make to the DOM in the hidden Div. I used facebox and found out that it makes a copy of the hidden div and changes to the DOM doesn't reflect on the modal window. I need to be able call the close modal div using javascript and also attach beforeOpen and afterClose handlers to the action. Does anyone have any suggestions? I have already tried facebox, simplemodal and a whole range of libraries, most of them don't support one or the other of these functions I described above.

Error mounting CloudDrive snapshot in Azure

- by Dave

Hi, I've been running a cloud drive snapshot in dev for a while now with no probs. I'm now trying to get this working in Azure. I can't for the life of me get it to work. This is my latest error: Microsoft.WindowsAzure.Storage.CloudDriveException: Unknown Error HRESULT=D000000D ---> Microsoft.Window.CloudDrive.Interop.InteropCloudDriveException: Exception of type 'Microsoft.WindowsAzure.CloudDrive.Interop.InteropCloudDriveException' was thrown. at ThrowIfFailed(UInt32 hr) at Microsoft.WindowsAzure.CloudDrive.Interop.InteropCloudDrive.Mount(String url, SignatureCallBack sign, String mount, Int32 cacheSize, UInt32 flags) at Microsoft.WindowsAzure.StorageClient.CloudDrive.Mount(Int32 cacheSize, DriveMountOptions options) Any idea what is causing this? I'm running both the WorkerRole and Storage in Azure so it's nothing to do with the dev simulation environment disconnect. This is my code to mount the snapshot: CloudDrive.InitializeCache(localPath.TrimEnd('\\'), size); var container = _blobStorage.GetContainerReference(containerName); var blob = container.GetPageBlobReference(driveName); CloudDrive cloudDrive = _cloudStorageAccount.CreateCloudDrive(blob.Uri.AbsoluteUri); string snapshotUri; try { snapshotUri = cloudDrive.Snapshot().AbsoluteUri; Log.Info("CloudDrive Snapshot = '{0}'", snapshotUri); } catch (Exception ex) { throw new InvalidCloudDriveException(string.Format( "An exception has been thrown trying to create the CloudDrive '{0}'.

Please help as this has me royally stumped! Thanks in advance. Dave

I am trying to make each number displayed clickable. "1" should alert() 80, "2" should produce 60, etc. However, when the alert(adjust) is called, it only shows 0, not the correct numbers. However, if the commented out alert(adjust) is uncommented, it produces the correct number on page load, but not on clicking. I was wondering why the code inside addEvents cannot access the previously defined variable adjust. <html> <head> <script type="text/javascript" charset="utf-8" src="mootools.js"></script> <script type="text/javascript" charset="utf-8"> window.addEvent('domready', function() { var id_numbers = [1,2,3,4,5]; for(var i = 0; i<id_numbers.length; i++) { var adjust = (20 * (5 - id_numbers[i])); // alert(adjust); $('i_' + id_numbers[i]).addEvents({ 'click': function() { alert(adjust); } }); } }); </script> </head> <body> <div id="i_1">1</div> <div id="i_2">2</div> <div id="i_3">3</div> <div id="i_4">4</div> <div id="i_5">5</div> </body> </html> Thanks.

Symbolicate adhoc iphone app crashes.

- by gotye

Hey everyone, I can't manage to make my code symbolicated ... I read the part "below" : Given a crash report, the matching binary, and its .dSYM file, symbolication is relatively easy. The Xcode Organizer window has a tab for crash reports of the currently selected device. You can view externally received crash reports in this tab - just place them in the appropriate directory. This is the same as the Mac OS X directory described in the first section. It doesn't matter which device you have tethered, but the directory in which you place the crash report must be the directory for the tethered and selected device. It is not necessary to place the binary and .dSYM file in any particular location. Xcode uses Spotlight and the UUID to locate the correct files. It is necessary, though, that both files be in the same directory and that this directory is one that is indexed by Spotlight. Anywhere in your home directory should be fine. But it doesn't work for me ... here is what I did : I opened xcode organizer and I had my iphone device with crash logs App and dsym files are in my xcode project which is on my desktop All the rest should be automatic, right ? but crash logs aren't symbolicated yet ... Any comments welcome. Cheers. Gotye.

TinyMCE Image Alignment

- by will.earp.co.uk

TinyMCE has always been a little difficult to align images. Either the align tag, or adding style="float: left;" has been it solution. Ideally I would just like to add class="left" or class="right" so that I can set the border and margins of the image. Up until now the only way to do this without using the advimage plugin was to insert the image, then select it, the select a style from the style menu. Ideally I should be able to use the align control in the image dialogue to set the alignment class or use the alignment controls on the toolbar when in the main editing window. I have just again started looking at a solution to this, now that IE6 is finally starting to die, I can use CSS attributes in selectors, so IMG[style="float: left;"] {} Works, but I would rather use a class incase there are any other style attributes which will cause the selector to fail. And it doesn't work in IE6, and you know some corporate clients will still be running the bloody thing! So I looked through the TinyMCE documentation and found the formats configuration option, that seems to allow you to specify how tinyMCE applies code for various operations. Here I can add the IMG tag as a selector, and have classes: "left" for the alignleft function. This applies the class correctly when the alignment is selected from the toolbar, but it still writes an inline style when the alignment is selected through the image dialogue. Am I doing something wrong or is there a better way of doing this that will allow my clients to select image alignment from both the image dialogue and the toolbar, whilst applying a class to the image?

Sometimes Xcode appears to ignore target build settings?

- by Derek Clarkson

Hi all, I've created a iPhone static library project with two targets like this Project -- Library (Device) target -- Library (simulator) target The device target has the SDK set to the device so it produces an armv6/7 library and the simulator target is set to the simulator SDK so it produces an i386 library. The issue I'm having is that the SDK settings on the targets keep getting overridden by the XCode active target setting. i.e. if I build the device target, but the XCode window is showing the active SDK as being the simlulator, XCode will build a simulator library instead of a device library, ignoring the settings of the target. Although it will put it into the *-iphoneos/ directory in the build directories! I originally had the same issue with another static library project, and after a lot of playing around got everything to work correctly. i.e. The targets ignore the XCode active SDK because they have their own specifications of what to build. The problem is that I don't know what made it work in that project and I have not been able to reproduce the issue in it either. Does anyone have any ideas as to what is going on? ciao Derek
