  • UIButton in UITableViewCell events not working

    - by Tristan
    I see this problem all over the net, and none of the solutions listed work for me! I have added UIButton to a UITableViewCell in IB. I have assigned a custom UITableViewCell class to the UITableViewCell. My custom UITableViewCell class has an IBAction that im connecting to the Touch Up Inside event (I have tried other events they all don't work) but the IBAction function is never called! There is nothing else in the UITableViewCell, I have added the UIButton directly into the Content View. And everything has user interaction enabled! It is as simple as that I have nothing complex going on! What is is about a UITableViewCell that stops buttons working? EDIT: By request the code where I initialize my UITableViewCells the custom class is called DownloadCell - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"DownloadCell"; DownloadCell *cell = (DownloadCell *)[aTableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { UIViewController * cellController = [[UIViewController alloc] initWithNibName:@"DownloadCell" bundle:nil]; cell = (DownloadCell *)cellController.view; [cellController release]; } SoundLibrarianIPhoneAppDelegate * del = (SoundLibrarianIPhoneAppDelegate *)[UIApplication sharedApplication].delegate; DownloadQueue * dq = del.downloadQueue; DownloadJob * job = [dq getDownloadJob: indexPath.row]; [job setDelegate:self]; SoundInfo * info = [job sound]; NSArray * seperated = [info.fileName componentsSeparatedByString: @"."]; NSString * displayName = [seperated objectAtIndex:0]; displayName = [displayName stringByReplacingOccurrencesOfString:@"_" withString:@" "]; displayName = [displayName capitalizedString]; [cell.titleLabel setText: displayName]; cell.progressBar.progress = job.percentCompleted; [cell.progressLabel setText: [job getProgessText]]; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.userInteractionEnabled = YES; [cell setDelegate:self]; return cell; }

  • C# - Possible to use IOCTL

    - by theblip
    I'm trying to code for a Point Of Sale system which allows for a "Cash Drawer" attachment. Code is provided in the manual for opening the cash drawer (in C++ using IOCTL). Since I am coding in C# .NET, is it possible to perform something similar from within C# or will I have to write some unmanaged code? Am I able to get a handle to "\\.\ADVANSYS" from within C#? Do I need to use DLLImport? Would appreciate it if someone could point me in the right direction. // IOCTL Codes #define GPD_TYPE 56053 #define ADV_OPEN_CTL_CODE CTL_CODE(GPD_TYPE, 0x920, METHOD_BUFFERED, FILE_ANY_ACCESS) #define ADV_STATUS_CTL_CODE CTL_CODE(GPD_TYPE, 0x900, METHOD_BUFFERED, FILE_ANY_ACCESS) void OpenDrawer(UCHAR uWhichDrawer) // uWhichDrawer = 1 => CD#1, uWhichDrawer = 2 => CD#2 { HANDLE hFile; BOOL bRet UCHAR uDrawer = uWhichDrawer; // Open the driver hFile = CreateFile(TEXT("\\\\.\\ADVSYS"), GENERIC_WRITE | GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0); if (m_hFile == INVALID_HANDLE_VALUE) { AfxMessageBox("Unable to open Cash Drawer Device Driver!"); return; } // Turn on the Cash Drawer Output (Fire the required solenoid) bRet = DeviceIoControl(hFile, ADV_CD_OPEN_CTL_CODE, &uDrawer, sizeof(uDrawer), NULL, 0, &ulBytesReturned, NULL); if (bRet == FALSE || ulBytesReturned != 1) { AfxMessageBox("Failed to write to cash drawer driver"); CloseHandle(hFile); return; } CloseHandle(hFile); }

  • Delphi - E2010 Incompatible types: 'Integer' and 'Char' - Any ideas

    - by zeencat
    I've been tasked with porting a legacy Delphi application over to C# .Net. The original delphi developer left several months before I was hired. I'm receiving the E2010 Incompatible types: 'Integer' and 'Char' error for the below method. I'm trying to compile the application within the Delphi 2007 IDE, I've been told that original application is either Delphi 4 or 5 if that helps any. I understand what the error is telling me but I don't understand why\how it is applied to the code snippet below. Any help\direction would be greatly appreciated. Thanks in advance function StrIComp_JOH_PAS_1(const Str1, Str2: PChar): Integer; var Ch1, Ch2 : Char; Offset : Integer; PStr : PChar; begin; PStr := Str1; Offset := Str2 - PStr; repeat Ch1 := Upper[PStr^]; Ch2 := Upper[PStr[Offset]]; if (Ch1 = #0) or (Ch1 <> Ch2) then Break; Inc(PStr); until False; Result := Integer(Ch1) - Integer(Ch2); end;

  • VS2008 -> VS2010 leads to cryptic STL errors

    - by Jakobud
    The following C++ library was successfully compiled in VS2008 http://sourceforge.net/projects/xmlrpcc4win/files/xmlrpcc4win/XmlRpcC4Win1.0.8.zip/download When I open it in VS2010, it goes through the conversion wizard process without any errors. Now, when I attempt to compile it in VS2010, I get some weird STL errors like these: 1>TimXmlRpc.cpp(1018): error C2039: 'back_insert_iterator' : is not a member of 'std' 1>TimXmlRpc.cpp(1018): error C2065: 'back_insert_iterator' : undeclared identifier 1>TimXmlRpc.cpp(1018): error C2275: 'XmlRpcValue::BinaryData' : illegal use of this type as an expression 1>TimXmlRpc.cpp(1018): error C2065: 'ins' : undeclared identifier 1>TimXmlRpc.cpp(1018): error C2039: 'back_inserter' : is not a member of 'std' 1>TimXmlRpc.cpp(1018): error C3861: 'back_inserter': identifier not found 1>TimXmlRpc.cpp(1019): error C2065: 'ins' : undeclared identifier 1>TimXmlRpc.cpp(1031): error C2039: 'back_insert_iterator' : is not a member of 'std' 1>TimXmlRpc.cpp(1031): error C2065: 'back_insert_iterator' : undeclared identifier 1>TimXmlRpc.cpp(1031): error C2275: 'std::vector<_Ty>' : illegal use of this type as an expression 1> with 1> [ 1> _Ty=char 1> ] 1>TimXmlRpc.cpp(1031): error C2065: 'ins' : undeclared identifier 1>TimXmlRpc.cpp(1031): error C2039: 'back_inserter' : is not a member of 'std' 1>TimXmlRpc.cpp(1031): error C3861: 'back_inserter': identifier not found 1>TimXmlRpc.cpp(1032): error C2065: 'ins' : undeclared identifier I'm not sure what to make of some of these. For instance, back_insert_iterator is in fact a member of std, but VS doesn't seem to think it is. How do I fix errors like these? They just don't seem to make much sense so I'm not sure where to begin. Perhaps its something in my project settings? For example, here is line 1018, which gives the std error: std::back_insert_iterator<BinaryData> ins = std::back_inserter(*(u.asBinary)); If anyone could give me some direction I'd appreciate it. I'm new enough to C++ that I'm having a tough time figuring out this one.

  • .htaccess - RewriteRules working, but browser address bar displaying full (unfriendly) URL

    - by axol
    Hey there, Haven't been able to find a solution to this around the net or these forums - apologise if I've missed something! My .htaccess RewriteRules are working well - have search-engine and user -friendly links in my web pages, and unfriendly database URLs running hidden in the background. Except when I added a RewriteRule to add "www." to the front of URLs if the user didn't enter it - to ensure only one appears in search engines. Here's what now happening, and I can't figure out why! My friendly URL structure for content is like this, and the database query string uses the first "importantword": www.example.com/importantword-nonimportantword/ .htaccess snippet: Options +FollowSymLinks Options -Indexes RewriteEngine on RewriteOptions MaxRedirects=10 RewriteBase / RewriteRule ^/$ index.php [L] RewriteRule ^(.*)-(.*)/overview/$ detail.php?categoryID=$1 [L] RewriteCond %{HTTP_HOST} !^www.example.com$ RewriteRule ^(.*)$ http://www.example.com/$1 [L] What's happening since I added the last 2 lines: CASE 1: user types (or clicks) www.example.com/honda-vehicle/overview/ - Works correctly - They are taken to the correct page and the browser URL bar says: www.example.com/honda-vehicles/overview/ CASE 2: user types example.com - Works correctly - They are taken to www.example.com and the browser URL bar says: www.example.com CASE 3: user types (or clicks) example.com/honda-vehicles/overview/ i.e. without the prefix "www" - Does NOT work correctly - They are taken to the right page, but the browser URL bar displays the unfriendly URL: www.example.com/detail.php?categoryID=honda I figure there's some issue with the order of the RewriteRules, but it's doing my head in trying to logically step through it and figure it out! Any assistance at all or pointers would be most appreciated!

  • WCF deadlock when using callback channel

    - by mafutrct
    This is probably a simple mistake, but I could not figure out what was wrong. I basically got a method like this: [ServiceBehavior ( ConcurrencyMode = ConcurrencyMode.Reentrant, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true) ] public class Impl : SomeContract { public string Foo() { _CallbackChannel.Blah(); return ""; } } Its interface is decorated: [ServiceContract ( Namespace = "http://MyServiceInterface", SessionMode = SessionMode.Required, CallbackContract = typeof (WcfCallbackContract)) ] public interface SomeContract { [OperationContract] string Foo (); } The service is hosted like this: ServiceHost host = new ServiceHost (typeof (Impl)); var binding = new NetTcpBinding (); var address = new Uri ("net.tcp://localhost:8000/"); host.AddServiceEndpoint ( typeof (SomeContract), binding, address); host.Open (); The client implements the callback interface and calls Foo. Foo runs, calls the callback method and returns. However, the client is still struck in the call to Foo and never returns. The client callback method is never run. I guess I made a design mistake somewhere. If needed, I can post more code. Any help is appreciated.

  • MP3 Decoding on Android

    - by Rob Szumlakowski
    Hi. We're implementing a program for Android phones that plays audio streamed from the internet. Here's approximately what we do: Download a custom encrypted format. Decrypt to get chunks of regular MP3 data. Decode MP3 data to raw PCM data in a memory buffer. Pipe the raw PCM data to an AudioTrack Our target devices so far are Droid and Nexus One. Everything works great on Nexus One, but the MP3 decode is too slow on Droid. The audio playback starts to skip if we put the Droid under load. We are not permitted to decode the MP3 data to SD card, but I know that's not our problem anyways. We didn't write our own MP3 decoder, but used MPADEC (http://sourceforge.net/projects/mpadec/). It's free and was easy to integrate with our program. We compile it with the NDK. After exhaustive analysis with various profiling tools, we're convinced that it's this decoder that is falling behind. Here's the options we're thinking about: Find another MP3 decoder that we can compile with the Android NDK. This MP3 decoder would have to be either optimized to run on mobile ARM devices or maybe use integer-only math or some other optimizations to increase performance. Since the built-in Android MediaPlayer service will take URLs, we might be able to implement a tiny HTTP server in our program and serve the MediaPlayer with the decrypted MP3s. That way we can take advantage of the built-in MP3 decoder. Get access to the built-in MP3 decoder through the NDK. I don't know if this is possible. Does anyone have any suggestions on what we can do to speed up our MP3 decoding? -- Rob Sz

  • Silverlight: Problem using CellEditingTemplate

    - by Charles
    Hello Silverlight gurus, I am experiencing a problem with the DataGrid where my data-bound object's properties are not being updated when using the CellTemplate/CellEditingTemplate: <data:DataGridTemplateColumn Header="Text"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Text}" ></TextBlock> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> <data:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <TextBox Text="{Binding Text, Mode=TwoWay}" /> </DataTemplate> </data:DataGridTemplateColumn.CellEditingTemplate> </data:DataGridTemplateColumn> I am binding to a code-gen'd entity via the RIA Services. I've added an event handler to the PropertyChanged event, and it is never fired. However, if I do not use a template and instead use a DataGridTextColumn, everything works fine. I'm sure this sounds like an easy fix - I'm only using a TextBox in my editing template, so why not us a DataGridTextColumn? The problem is that I want to have a multi-line textbox, so using the DataGridTextColumn is not an option. Any suggestions? Do you know of any differences between using a CellEditingTemplate containing a single TextBox and using a DataGridTextColumn? Thanks, -Charles [UPDATE] I posted a bug report here: http://silverlight.net/forums/p/118729/267521.aspx I can't imagine that this is "as-designed"... If someone else has known about this and I'm just being dumb, I'd appreciate an explanation - I'd prefer embarrassment over ignorance :).

  • MSDeploy migrate only configuration from IIS 6 to 7

    - by Matt
    We have 19 websites, many of which have many "virtual" directories, on a IIS 6 server. I am trying to migrate the whole thing over to IIS 7 on a different server. Following the instructions on http://learn.iis.net/page.aspx/427/migrate-a-web-site-from-iis-60-to-iis-70/ I attempted the following command line execution: msdeploy -verb:sync -source:metakey=lm/w3svc -dest:package=D:\Temp\Sites.zip > D:\temp\WebDeployPackage.log It appeared to be working until I got a "There is not enough space on the disk" error. The D drive, which you'll notice is the target location for the package and the log has plenty of space (all the resources for the websites are about 5gb, the drive has 200+). Though the C drive is of limited size (6Gb), so that might be the problem. Anyway, I figure the best bet was to try and do a migration of settings/configurations only, not the actual resources. We can easily deploy the resources to the new server with our NAnt build scripts, so that's not an issue. Getting all the correct configurations moved over, however, would be challenging to do manually. So, is there a way to export/package only the configuration/options of the IIS 6 server using msdeploy (or any other tool?)

  • MSTest: Problems with DeploymentItem attribute

    - by Juri
    Hi, I'm currently maintaining an "old" system written in C#.net, removing some obsolete features and doing some refactoring. Thanks god, the previous guy wrote some unit tests (MSTests). I quite comfortable with JUnit tests, but didn't do yet much with MSTests. The test methods have a DeploymentItem attribute, specifying a text file which is parsed by the business logic method that is being tested and a 2nd DeploymentItem where just a path has been specified containing a bunch of TIF files that have to be deployed too. [TestMethod()] [DeploymentItem(@"files\valid\valid_entries.txt")] [DeploymentItem(@"files\tif\")] public void ExistsTifTest() { ... } The tests worked before, but now I had to change the names of the TIF files contained in the \files\tif directory. According to a rule, the TIF filenames have to match a certain pattern which is also checked by the ExistsTifTest() method. Now I had to change the filenames in order to adapt them to the new requirements and suddently the TIF files are no more being deployed as before. Can someone give me a hint why this happens or what may be the cause? The same thing happens also if I add a new text-file say "my2ndTest.txt" beside the "valid_entries.txt" in the \files\valid\ directory with the according DeploymentItem attribute on the test method. The file doesn't get deployed? I got the images now deployed by defining the deployment path directly in the testrunconfig, but I'd like to understand why these things happen or why for instance my new file "my2ndTest.txt" doesn't get deployed while the others do. Thanks a lot. Juri

  • SSRS 2008 Report Manager Error

    - by Nick
    I have just installed SQL Server 2008 including Reporting Services on Windows Server 2003. I'm having a problem though accessing the Report Manager. When the Reporting Service is first started I can access it fine but after maybe an hour when I try and access it I get an error saying: Unable to connect to the remote server. The reporting service is still running at this point. I can connect to it through Reporting Services Configuration Manager and clicking on the Web Service URL gives a directory listing (I assume that is correct behaviour). If I stop and start the service through Reporting Services Configuration Manager then I can access Report Manager once again (although in maybe an hour I will get the same error once again). I've installed the latest SP1 service pack. I'm using the same domain account to run all the SQL services. The report server is set to use the default ReportServer virtual directory, is set to IP address All Assigned, TCP Port 80 and no SSL certificate. The report manager is set to use the default Reports virtual directory, IP address All Assigned, TCP Port 80 and no SSL certificates. In the log file I get an error: Unable to connect to remote server HTTP status code 500 An attempt was made to access a socket in a way forbidden by its access permissions. Does anyone have any idea why this is happening? I've searched the net but haven't been able to find a solution.

  • Windows services with windows forms in the same process

    - by andrecarlucci
    Hello, I have a c# application that runs as a windows service controlling socket connections and other things. Also, there is another windows forms application to control and configure this service (systray with start, stop, show form with configuration parameters). I'm using .net remoting to do the IPC and that was fine, but now I want to show some real traffic and other reports and remoting will not meet my performance requirements. So I want to combine both applications in one. Here is the problem: When I started the form from the windows service, nothing happened. Googling around I've found that I have to right click the service, go to Log on and check the "Allow service to interact with desktop" option. Since I don't want to ask my users to do that, I got some code googling again to set this option in the user's regedit during installation time. The problem is that even setting this option, it doesn't work. I have to open the Log On options of the service (it is checked), uncheck and check again. So, how to solve that? How is the best way to have a windows service with a systray control in the same process, available to any user logging in? UPDATE: Thanks for the comments so far, guys. I agree it is better to use IPC and I know that it is bad to mix windows services and user interfaces. Even though, I want to know how to do that.

  • c# How to Verify Signature, Loading PUBLIC KEY From PEM file?

    - by bbirtle
    I'm posting this in the hope it saves somebody else the hours I lost on this really stupid problem involving converting formats of public keys. If anybody sees a simpler solution or a problem, please let me know! The eCommerce system I'm using sends me some data along with a signature. They also give me their public key in .pem format. The .pem file looks like this: -----BEGIN PUBLIC KEY----- MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDe+hkicNP7ROHUssGNtHwiT2Ew HFrSk/qwrcq8v5metRtTTFPE/nmzSkRnTs3GMpi57rBdxBBJW5W9cpNyGUh0jNXc VrOSClpD5Ri2hER/GcNrxVRP7RlWOqB1C03q4QYmwjHZ+zlM4OUhCCAtSWflB4wC Ka1g88CjFwRw/PB9kwIDAQAB -----END PUBLIC KEY----- Here's the magic code to turn the above into an "RSACryptoServiceProvider" which is capable of verifying the signature. Uses the BouncyCastle library, since .NET apparently (and appallingly cannot do it without some major headaches involving certificate files): RSACryptoServiceProvider thingee; using (var reader = File.OpenText(@"c:\pemfile.pem")) { var x = new PemReader(reader); var y = (RsaKeyParameters)x.ReadObject(); thingee = (RSACryptoServiceProvider)RSACryptoServiceProvider.Create(); var pa = new RSAParameters(); pa.Modulus = y.Modulus.ToByteArray(); pa.Exponent = y.Exponent.ToByteArray(); thingee.ImportParameters(pa); } And then the code to actually verify the signature: var signature = ... //reads from the packet sent by the eCommerce system var data = ... //reads from the packet sent by the eCommerce system var sha = new SHA1CryptoServiceProvider(); byte[] hash = sha.ComputeHash(Encoding.ASCII.GetBytes(data)); byte[] bSignature = Convert.FromBase64String(signature); ///Verify signature, FINALLY: var hasValidSig = thingee.VerifyHash(hash, CryptoConfig.MapNameToOID("SHA1"), bSignature);

  • UINavigationController inside tabbar loading a child root view

    - by Doug
    Hi guys, Firstly i'll preface by saying that i am a complete Cocoa touch/objective c noob (.Net dev having a dabble) I have searched on Google as well as here but cannot seem to find an easy solution. I have a UItabbarcontroller view with a UINavigationController inside its first tab I have the root view for this UINavigationController stored in a seperate class and NIB as i am trying to seperate the data viewing from the data loading (i'm going to reuse the table list in multiple places in my database) and simply pass the root view its data using a loading method and have it take it from there. What i want to happen: App loads and loads the first view of the tab bar (A UINavigationController) The UINavigationController inside the first view loads a root view (a UIViewController with a table view) and sets its title The UINavigationController loads the data from a web service and parses it The UINavigationController sends the data to a loading method inside the UIViewController Am i thinking about this completely wrongly? What currently happens: the first tab bar loads with an empty uinavigationcontroller (no table view) the data methods fire and get the webservice data this child view gets sent its data using the loading method the tableview delegate events fail to fire inside the child view telling it to load the data into the table I just can't seem how to load my second view inside the root view of the navigation controller and then send it my data?

  • how many types of code signing certificates do I need?

    - by gerryLowry
    in Canada, website SSL certificates can be had for as low as US$10. unfortunately, code signing certificates cost about 10 time as much, one website mentions Vista compatibility ... this seems strange because my assumption is they must support XP, Vista, Windows 7, Server 2003, and Server 2008 or they would be useless. https://secure.ksoftware.net/code_signing.html US$99 Support Platforms Microsoft Authenticode. Sign any Microsoft executable format (32 and 64 bit EXE, DLL, OCX, DLL or any Active X control). Signing hardware drivers is not currently supported. Abode AIR. Sign any Adobe AIR application. Java. Sign any JAR applet Microsoft Office. Sign any MS Office Macro or VBA (Visual Basic for Applications) file. Mozilla. Sign any Mozilla Object file. The implication is that a single code signing certificate can do ALL of the above. ksoftware actually discounts Commodo certificates and the Commode website is unclear. QUESTION: Will ONE code signing certificate be enough or do I need one for Microsoft executables, and a second for things like Word and Excel macros? my main goal is to sign things like vs2008 code snippets so that I can export them securely; however, I would like to be able to use the same code signing certificate for signing other items too. Thank you ~~ regards, Gerry (Lowry)

  • Installing MonoTouch - ibtool not found error

    - by Nic Wise
    I've had Xcode (3.2.1 - SnowLeopard, iphone 3.1.3) installed for a while, and I can run and build apps on it fine. I installed MonoTouch, as I want to leverage the 8+ years of .NET skills I have :) So I installed: Mono: MonoFramework-2.6.1_1.macos10.novell.x86 MonoTouch: monotouch-eval-1.5.0 MonoDevelop: MonoDevelop-2.2.1-r152508 (was 2.2.1, but when I started it up, it said there was an update, which I installed - thats the update version) If I make a new project and build it, I get any of the following errors: Build failed. Object reference not set to the instance of an object. Build failed: ibtool not found (btw, it's in /Developer/usr/bin/ibtool) or a similar one to the second one if I use the older (2.2.1 released) version of MonoTouch. I can't find any debug info anywhere. I could reinstall XCode/iPhone SDK, but as it already is installed and works (and no, this isn't a SL upgrade), it doesn't make sense. Anyone got any ideas? I SO want to use MonoTouch - Obj-C drives me up the wall! Console apps (mono ones) work fine. Mac OS X 10.6.2, Macbook Pro, clean install with old settings moved over.

  • Heroku and Github integration (how to structure the project)

    - by Noah
    I'm creating a webservice and I want to store the source on github and run the app on heroku. I haven't seen my exact scenario addressed anywhere on the 'net so far, so I'll ask it here: I want to have the following directory structure: /project .git README <-- project readme file TODO.otl <-- project outline ... <-- other project-related stuff /my_rails_app app config ... README <-- rails' readme file In the above, project corresponds to http://github.com/myuser/project, and my_rails_app is the code that should be pushed to heroku. Do I need a separate branch for the rails app, or is there a simpler way that I'm missing? I guess my project-related non-rails files could live in my_rails_app, but the rails README already lives there and it seems inconsistent to overwrite that. However, if I leave it, my github page for the rails app will contain the rails readme, which makes no sense. Thanks, Noah P.S. I tried just setting it up as described above and running git push heroku from the main project folder. Of course, heroku doesn't know I want to deploy the subfolder: -----> Heroku receiving push ! Heroku push rejected, no Rails or Rack app detected.

  • cellForRowAtIndexPath not being called on tableView reloadData

    - by BotskoNet
    I have a UITableView on one view that loads in data at the start of the application, and then later when a user enters text into a box and hits a button, I re-query the database, re-populate the original NSMutableArray that stores the data for the table. All of that is working perfectly. In some logging statements I can tell that the array has the correct information, the numberOfRowsInSection method is returning the proper count, and is being called after the reload is called. However, the cellForRowAtIndexPath is never called the second time (after the reload) and the table data is never updated. I've spent hours searching the net and I've found nothing that helps. Can anyone help? All code is at: http://github.com/botskonet/inmyspot The specific reload is being called at: http://github.com/botskonet/inmyspot/blob/master/Classes/InMySpotViewController.m Roughly Line 94 From: http://github.com/botskonet/inmyspot/blob/master/Classes/PlateFormViewController.m Roughly line 101 A bit more info: once the new data has been added to the mutablearray, if I try to start scrolling the table, it eventually dies with: "Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (29) beyond bounds (29)'" Which I assume means the table cells can't find any data in the array to match the scroll position, which seems to be because the array has the new data, but the table doesn't.

  • Silverlight: Download local files with WebClient

    - by David
    The directory structure of my Silverlight project is like the following: \Bin - MainModule.xap - \Images --- Image1.png --- Image2.png - \Modules --- SubModule.xap I want to be able to run it through either a web server or through Visual Studio directly (for debugging purposes I want to bypass content downloading). In my media loading code I do something like the following: if (runningLocally) { var bitmapImage = new BitmapImage(); bitmapImage.UriSource = new Uri("Images/Image1.png", UriKind.Relative); var image = new Image(); image.Source = bitmapImage; } else { WebClient wc = new WebClient(); wc.OpenReadCompleted += (s, e) => { var bitmapImage = new BitmapImage(); bitmapImage.SetSource(e.Result); var image = new Image(); image.Source = bitmapImage; }; wc.OpenReadAsync(new Uri("Images/Image1.png", UriKind.Relative)); } This works for images but I also have sub-modules which are just assemblies housing UserControls. Since Silverlight has no ability to read disk I've resigned myself to the fact that I'm going to have to "download" the XAPs I need whether I'm running locally or not. Problem is if I run the project locally and try to use a WebClient to download a XAP I get an exception: System.Net.WebException: An exception occurred during a WebClient request. ---> System.NotSupportedException: The URI prefix is not recognized. Is there any way (WebClient or otherwise) I can get to my sub-module XAPs when running the Silverlight project directly rather than hitting a web server?

  • Redrawing rounded corners when using curvycorners-plugin for jQuery.

    - by timkl
    I'm using the curvycorners jQuery plugin (http://www.curvycorners.net/instructions/) to force IE to render rounded corners on divs. It works really well, apart from one thing: I have a validation error-message that pops up inside the div, using jQuery's "show" method. Curvycorners adds an extra div that is absolute positioned and has a set height, this means that you have to redraw the rounded corners if you want the containing div to resize when the error-message is shown. Curvycorners include a functions you can call to redraw the rounded corners, however it doesn't execute when I put it inside this click-function: $("input[type='submit']").click(function(e) { curvyCorners.redraw(); }); This is my markup: <fieldset class="curvyRedraw"> <legend>Some legend</legend> <form id="someForm"> <div id="error-message"></div> <div class="buttons"> <input type="submit" id="cancel" value="Cancel" name="action" /> <input type="submit" id="submit" value="Confirm" name="action" /> </div> </form> </fieldset> Anyone had similar issues?
