• Consuming an RPC/encoded Web Service in .NET

  - by Timmy O' Tool

  I'm trying to build the proxy class for a web service using the wsdl Executing this command: wsdl [http://WSDL_URL] I'm getting Warning: This web reference does not conform to WS-I Basic Profile v1.1. R2706: A wsdl:binding in a DESCRIPTION MUST use the value of "literal" for the use attribute in all soapbind:body, soapbind:fault, soapbind:header and soapbind:headerfault elements. ... Error: Cannot find definition for http://schemas.xmlsoap.org/wsdl/:BouBinding. Service Description with namespace http://schemas.xmlsoap.org/wsdl/ is missing. Parameter name: name The author of the web service told me that the SOAP protocol is RPC/encoded. Is there is any way to generate a proxy class for this?

• Apache rewriteBase in .htaccess for development subdomains

  - by Das123

  I think I'm missing something and don't think I really understand how rewriteBase works. The problem I have is that I have a production site where the site is in the root directory yet I have my development site in a localhost subdirectory. Eg http://www.sitename.com/ vs http://localhost/sitename/ If I have for example an images folder I want to reference the images from the site root by using the initial slash in the href. Eg Using a relative href (without the initial slash) is not an option. This will work on the production site but the development site is looking for http://localhost/images/imagename.jpg instead of http://localhost/sitename/images/imagename.jpg So I thought all I needed to do was setup the following in my .htaccess file to force the site root to my subdomain within the development environment: Options +FollowSymLinks RewriteEngine On RewriteBase /sitename But this still uses localhost as the site root instead of localhost/sitename. Can anyone please give me some pointers?

• After adding a UILabel to my view, how do I delete it?

  - by Travis

  I have added a UILabel to my view programmatically like this: myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 30.0f)]; myLabel.center = CGPointMake(160.0f, 120.0f); myLabel.backgroundColor = [UIColor clearColor]; myLabel.textColor = [UIColor whiteColor]; myLabel.font = [UIFont fontWithName:@"Helvetica" size: 18.0]; myLabel.textAlignment = UITextAlignmentCenter; myLabel.text = @"Hello"; [self.myView addSubview:myLabel]; To add a label to my view. What I can't seem to find out is once I'm done w/ the label (at a future point) how can I delete it from the view? [myLabel release] doesn't seem to work which I think makes sense because the view it's added to probably retained it's over reference. So what is the best practice?

• How to include simple collections in ConfigurationSection

  - by mikemanne

  Is there a way for me to include a simple array of strings, or List<string> on my custom subclass of ConfigurationSection? (Or an array or generic list of simple data objects, for that matter?) I'm becoming familiar with the new (and VERY verbose) ConfigurationSection, ConfigurationElement, and ConfigurationElementCollection classes, but I'm by no means an expert yet. It seems like ConfigurationSection should handle simple collections/lists on its own, without me having to create a custom ConfigurationElementCollection subclass for each and every one. But I haven't found any reference to this ability online.

• RenderAction in an HtmlHelperExtension Method?

  - by TimLeung

  I am trying to call the RenderAction Extension Method within my own Html Helper: System.Web.Mvc.Html.ChildActionExtensions.RenderAction(helper, "account", "login"); this is so that along with some additional logic, I would like all html helpers to use a common method name structure when calling it on the view: <%= Html.CompanyName().RenderAccount() %> but the problem I am having is that, asp.net will complain about not finding the actual route it needs to process. It does not take in the parameters of "controller" to be used as the action and "login" to be used as the action. It seems to only reference the current route. Any ideas how I can package up the RenderAction?

• Why is the servlet request not available in the portlet API

  - by John Smith

  The portlet API deos not provide any reference to the enclosing servlet request and response objects. I know it is not the preferred model of interaction with the user, but it seems draconian to remove all access. I understand that for portlet driven interaction with the user, you want to use portlet URLs, and let the portlet container manage all the complexity. However if you have a number of portlets which are basically showing variants of the same data, it makes sense for them to be able to use the enclosing request to drive the data. We ended up using using a Liferay specific call to get the request, and it all seems to work as we wish. However I do feel the guilt. So my question really is, is there an underlying deep reason for the prohibition, or is it just to enforce the authors view of the API environment?

• How to detect the language of MS Excel from C#

  - by Babba

  If i try to use Excel from C# (interop) i receive error (HRESULT: 0x80028018) when current thread language is different from Excel language: so i need to set thread language, they must be the same. Which is the best method to understand the language of Excel/Office? 1) registry (HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\LanguageResources\UILanguage ? How understand wich version (12.0/14.0/...?) 2) with Application like suggested here (http://stackoverflow.com/questions/2804556/how-to-detect-the-language-of-ms-excel) ? It's ok but i need a strong reference to a specific version Microsoft.Office.Core and so i can't do it for different versione of Office: Excel.Application application = new Excel.Application(); int iUi = application.LanguageSettings.get_LanguageID(Microsoft.Office.Core.MsoAppLanguageID.msoLanguageIDUI); MessageBox.Show(iUi.ToString()); 3) other?

• Sum an Array - Objective-C

  - by Graham

  Hi Guys, I'm just starting out and I'm looking for an easy way to sum a simple array. I've read into apple developer site on key value coding and I don't understand how to apply that to my array or if that's the appropriate way to sum this. My stumbling block with the key value coding is the .keypathToProperty - I can sort of understand that you need a further reference in a 2D array but they don't show the array code, only the keypath to the title of the row so I can't figure it out yet. NSMutableArray *numArray = [NSMutableArray arrayWithCapacity:4]; [numArray addObject:num1]; [numArray addObject:num2]; [numArray addObject:num3]; [numArray addObject:num4]; I appreciate the replies! Thanks Graham

• Why does GetClusterShape return null when the cluster specification was retrieved through the GetClu

  - by Markus Olsson

  Suppose I have a virtual earth shape layer called shapeLayer1 (my creative energy is apparently at an alltime low). When i call the GetClusteredShapes method I get an array of VEClusterSpecification objects that represent each and every one of my currently visible clusters; no problem there. But when I call the GetClusterShape() method it returns null... null! Why on earth would it do that? I used firebug to confirm that the private variable of the VEClusterSpecification that's supposed to hold a reference to the shape is indeed null so it's not the method that's causing the problem. Some have suggested that this is actually documented behavior Returns null if a VEClusterSpecification object was returned from the VEShapeLayer.GetClusteredShapes Method But looking at the current MSDN documentation for the VEShape class it says: Returns if a VEClusterSpecification object was returned from the VEShapeLayer.GetClusteredShapes Method Is this a bug or a feature? Is there any known workarounds or (if it is a bug) some plan on when they are going to fix it?

• Using Thrift to connect to Cassandra from .NET

  - by vtortola

  Hi, I'm interested in Cassandra and I'd like to test it at home in my Windows XP computer. I've found instructions for install an run Cassandra in Windows, and it's already up and running; I've also found the thrift executable for Windows and generate the C# interfaces, but... when I try to compile that generated code in Visual Studio I got : "The type or namespace name 'Thrift' could not be found (are you missing a using directive or an assembly reference?)", so I'm missing something else, but I cannot find what... What is it? Is it a dll? I've looked in the thrift code and I cannot find anything related to .net , so what am I missing? Thanks in advance. Regards.

• Compiling Allegro source code (C#)

  - by 7331

  I am trying to build a C# project (downloaded code) in Visual Studio Express 2008. I get the error (my translation): The type or namespace name "Allegro" couldn't be found. for the line using Allegro; I know the 2D graphics library Allegro, of course, but I can't find much information on how to use it in C#. It is being used for visualization in the project I am trying to compile. I also get the warning This reference couldn't be resolved. The Universal assembly couldn't be found. I haven't been working with C# before and and I barely know Visual Studio Express. These are newbie mistakes - but I just need a fast solution for this problem. Could someone provide me with a short step-by-step solution?

• Mathematica Plot3D does not produce a plot when graphing a user-defined function?

  - by pythonscript

  I'm writing a simple Mathematica implementation of the black-scholes model and using Plot3D to plot the pricing surface. However, when I run this code, no plot is produced. My call and put functions to produce correct values when run separately, but no plot is produced. Code: Clear[d1, d2, call, put, stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] d1[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := (Log[stockPrice / strikePrice] + (riskFreeRate + 0.5*volatility^2)*timeToExp) / (volatility * Sqrt[timeToExp]) d2[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility] - volatility*Sqrt[timeToExp] call[stockPrice_, strikePrice_, riskFreeRate_, timeToExp_, volatility_] := stockPrice * CDF[NormalDistribution[0, 1], d1[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] - strikePrice * Exp[-riskFreeRate*timeToExp] *CDF[NormalDistribution[0, 1], d2[stockPrice, strikePrice, riskFreeRate, timeToExp, volatility]] Plot3D[call[stockPrice, 500, 0.0030, timeToExp, 0.39], {stockPrice, 10, 1000}, {timetoExp, 0.0833333, 5}] Other plots, like this sample from the reference, do work. Plot3D[{x^2 + y^2, -x^2 - y^2}, {x, -2, 2}, {y, -2, 2}, RegionFunction -> Function[{x, y, z}, x^2 + y^2 <= 4], BoxRatios -> Automatic]

  I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong?

• Samba share not accessible from Win 7 - tried advice on superuser

  - by Roy Grubb

  I have an old Red Hat Linux box that I use, amongst other things, to run Samba. My Vista and remaining Win XP PC can access the p/w-protected Samba shares. I just set up a new Windows 7 64-bit Pro PC. Attempts to access the Samba shares by clicking on the Linux box's icon in 'Network' from this machine gave a Logon failure: unknown user name or bad password. message when I gave the correct credentials. So I followed the suggestions in Windows 7, connecting to Samba shares (also checked here but found LmCompatibilityLevel was already 1). This got me a little further. If click on the Linux box's icon in 'Network' from this machine I now see icons for the shared directories. But when I click on one of these, I get \\LX\share is not accessible. You might not have permission... etc. I tried making the Win 7 password the same as my Samba p/w (the user name was already the same). Same result. The Linux box does part of what I need for ecommerce - the in-house part, it's not accessible to the Internet. As my Linux Fu is weak, I have to avoid changes to the Linux box, so I'm hoping someone can tell me what to do to Win 7 to make it behave like XP and Vista when accessing this share. Help please!? Thanks Thanks for replying @Randolph. I had set 'Network security: LAN Manager authentication level' to Send LM & NTLM - use NTLMv2 session security if negotiated based on the advice in Windows 7, connecting to Samba shares and had restarted the machine, but that didn't work for me. I'll try playing with other Network security values. I have now tried the following: Network security: Allow Local System to use computer identity for NTLM: changed from Not Defined to "Enabled". Restarted machine Still says "\LX\share is not accessible. You might not have permission..." etc. Network security: Restrict NTLM: Add remote server exceptions for NTLM Authentication (added LX) Restarted machine Still says "\LX\share is not accessible. You might not have permission..." etc. I can't see any other Network security settings that might affect this. Any other ideas please? Thanks Roy

• Google app engine - what is the lifecycle of PersistenceManager?

  - by Domchi

  What is the preferred way of using GAE datastore PersistenceManager for web app? GAE instructions are a bit ambiguous on the matter. Do I instantiate PersistenceManagerFactory for each RPC call, or do I use only one factory for all requests? Do I call PMF.get().getPersistenceManager(), or do I call PMF.get().getPersistenceManagerProxy()? Do I close PM after each RPC call, or do I leave it open? What are you guys doing? Furthermore, I'm not certain how GAE handles 30-second-per-request limit. Is it even possible to reference the same PM between requests?

• xerces serialization in Java 6

  - by Jim Garrison

  In Java 6, the entire xerces XML parser/serializer implementation is now in the Java runtime (rt.jar). The packages have been moved under the com.sun.* namespace, which places them off-limits for explicit reference within client code. This is not a problem when using the parser, which is instantiated via javax API-defined factories. However, our code also uses xerces serialization (org.apache.xml.serialize.* ). AFAICT, there are no javax.xml API-defined factories for creating instances of Serializer and OutputFormat. This seems to imply that the only way to get one is to explicitly call the com.sun.org.apache.xml.serialize.* APIs. I've found the serialization classes in javax.xml.stream, but they don't seem to provide any output-formatting control like the xerces OutputFormat class. Question: Is there a way to access the xerces serialization functionality (which is in rt.jar) via a javax standard API, without including xerces.jar and also without explicitly instantiating com.sun.* classes? If not, is there an javax API-compliant way to achieve the same effect?

• Centralised/shared COM DLL, possible?

  - by vikp

  Hi, We have a system that makes a use of 3rd party COM DLL written in vba We have a centralised web application and 1-50 client machines that must reference that COM DLL in order to use our centralised web application. The COM DLL is going to be updated rapidly in the future, which means that it has to be re-installed on every machine manually. Is it possible to centralise this COM DLL somwhere on the network? Is there any other alternatives? Otherwise the maintenance overhead will be huge... Thank you

• WCF does not generate the properties

  - by BDotA

  I have a .NET 1.1 ASMX and want to use it in a client WinForms app. If i go wit the old way and add it as a "WebRefrence" method then I will have access to two of its properties which are "url" and "UseDefaultCredentials" and it works fine. But if I go with the new WCF way and add it as a ServiceReference I still have access to the methods of that ASMX but those two properties are missing. what is the reason for that? so for example in the old way ( adding WebReference) these codes are valid: TransferService transferService= new TransferService(); transferService.Url = "http://something.asmx"; transferService.Credentials = System.Net.CredentialCache.DefaultCredentials; string[] machines = transferService.GetMachines(); But in the new way ( adding Service Reference ) using(TransferServiceSoapClient transferServiceSoapClient = new TransferServiceSoapClient("TransferServiceSoap")) { transferServiceSoapClient.Url = "someUrl.asmx"; //Cannot resolve URL transferServiceSoapClient.GetMachines(new GetMachinesRequest()); transferServiceSoapClient.Credentials = .... // //Cannot resolve Credentials }

• Cmake suddenly can't find my source files anymore...

  - by aheld

  To make a long story short: To add insult to injury, CMake actually ran fine several times. I was wrestling with a compiler error when CMake suddenly didn't feel like working anymore. For reference, here's the whole CMakeLists.txt file: set(CMAKE_INCLUDE_CURRENT_DIR ON) Find_Package ( SDL REQUIRED ) Find_Package ( SDL_image REQUIRED ) Find_Package ( SDL_mixer REQUIRED ) if ( NOT SDL_FOUND ) message ( FATAL_ERROR "Make sure that SDL is installed" ) endif ( NOT SDL_FOUND ) link_libraries ( ${SDL_LIBRARY} ${SDLIMAGE_LIBRARY} ${SDLMIXER_LIBRARY} SDLmain ) set(wiggle_SOURCES level.cpp levelgenerator.cpp main.cpp player.cpp scoreboard.cpp snake.cpp soundplayer.cpp titlescreen.cpp ) add_executable(Wiggle ../${wiggle_SOURCES}) The error occured for the first time when, instead of simply typing "make", I typed "make -lSDL -lSDL_image -lSDL_mixer" - make refused to find the header files SDL.h and SDL_image.h after I detached the project from Code::Blocks.

• Detecting when Bluetooth is disabled on iOS5

  - by Non Umemoto

  I'm developing blog speaker app. I wanna pause the audio when bluetooth is disabled like iPod app. I thought it's not possible without using private api after reading this. Check if Bluetooth is Enabled? But, my customer told me that Rhapsody and DI Radio apps both support it. Then I found iOS5 has Core Bluetooth framework. https://developer.apple.com/library/ios/documentation/CoreBluetooth/Reference/CoreBluetooth_Framework/CoreBluetooth_Framework.pdf CBCentralManagerStatePoweredOff status seems like the one. But, the description says this api only supports Bluetooth 4.0 low energy devices. Did anyone try doing the same thing? I want to support current popular bluetooth headsets, or bluetooth enabled steering wheel on the car. I don't know if it's worth trying when it only supports some brand new bluetooth.

• Renaming ICSharpCode.SharpZipLib.dll

  - by John B.

  Hi, well I am having a problem renaming the ICSharpCode.SharpZipLib.dll file to anythig else. I am trying to shorten the file name. I reference the assembly in the project, but when the program reaches the statements where I use the library. It spawns an error that it could not find the assembly or file 'ICSharpCode.SharpZipLib'. When I change the file name back to ICSharpCode.SharpZipLib.dll the application works noramally. So, is there any way to change the file name. Also, am I allowed to change it without violating the license (I am going to use it in a commercial application). Thanks.

• MPMediaickerController memory leak

  - by Joe

  This is code from Apple's Addmusic example. MPMediaPickerController *picker = [[MPMediaPickerController alloc] initWithMediaTypes: MPMediaTypeMusic]; picker.delegate = self; picker.allowsPickingMultipleItems = YES; picker.prompt = NSLocalizedString (@"Add songs to play", "Prompt in media item picker"); // The media item picker uses the default UI style, so it needs a default-style // status bar to match it visually [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleDefault animated: YES]; [self presentModalViewController: picker animated: YES]; [picker release]; I'm using this code in my app and the Leaks instrument highlights a leak on the line: [self presentModalViewController: picker animated: YES]; I think that this is because this line retains a reference to picker which cannot be subsequently released. Is there any way around this?

• UI Terminology - Enabled vs. Active

  - by Pamela

  When designing a feature that can be accessed by different user levels, I'm wondering how the use of "enabled" versus "active" will work. If I'm an administrator, it means I have the ability to turn on and off a feature. Does this mean the feature is enabled for me or active? Once I turn this feature on, is it then enabled or active? Terminology is the pits. On the subject, does anyone know of a reference book or site dedicated to questions regarding standard terminology for UIs? Thanks a million!

• Upgrade from .NET 2.0 to .NET 3.5 problems

  - by Bashir Magomedov

  I’m trying to upgrade our solution from VS2005 .NET 2.0 to VS2008 .NET 3.5. I converted the solution using VS2008 conversion wizard. All the projects (about 50) remained targeting to .NET Framework 2.0., moreover if I’m changing target framework manually for one of the projects, all referenced dll (i.e. System, System.Core, System.Data, etc. are still pointing to Framework 2.0. The only way to completely change targeting framework I found is to remove these references and refer them again using proper version of framework. Doing it manually is not best choice I think. 50 projects ~ 10 references each ~ 0.5 minutes for changing each reference is about 5 hours to complete. Am I missing something? Are there any other ways of converting full solution from .NET 2.0 to .NET 3.5? Thank you.
