  • Setting a Forms Authentication cookie from a .NET client application

    - by Jon DellOro
    We currently have a .NET 2.0 web app that uses forms authentication via cookies. Associated with this web app is an old VB6 client application that has its own login system. Currently, the users have to login to the VB6 app, and then when they click on a link, need to authenticate themselves again with the .NET forms authentication system. I'm wondering if it's possible to create a client side .NET application, give it the username and password, and set the forms authentication cookie (without the browser being opened). Is that possible??

  • Client-side framework for web-app with good audio support

    - by Poita_
    I'm trying to create a client-side web app that generates music procedurally using some user-input parameters, so I'm looking for a framework (e.g. Flash, Silverlight etc.) that has the capability to play audio at a specified pitch. Whether it is playing a WAV/MP3 file, using MIDI output, or just playing beeps doesn't really matter -- I just need something that will enable me to generate arbitrary music client-side. I've done a bit of searching and it appears that Flash might have the ability to change pitch with the help of a third-part plugin, but I couldn't find anything similar for Silverlight. I can go a try all them out manually if need be, but I thought I'd ask here first just in case anyone had tried something like this before. Thanks in advance

  • Statically Compiled Oracle Client Drivers/Code

    - by blockcipher
    Hello, I'm looking to write a command-line program that can execute database scripts against an Oracle server, however the machine the program will be run on may not have an Oracle client installed on it. I also don't want to rely on a language that requires a VM as there's no guarantee that the VM will be installed, so a language like C is preferable for this. Is there a way that I can statically compile/build this program and not have to have the user install the Oracle client on that machine? I'm trying to be as unobtrusive as possible. Thanks.

  • JSON or YAML encoding in GWT/Java on both client and server

    - by KennethJ
    I'm looking for a super simple JSON or YAML library (not particularly bothered which one) written in Java, and can be used in both GWT on the client, and in its original Java form on the server. What I'm trying to do is this: I have my models, which are shared between the client and the server, and these are the primary source of data interchange. I want to design the web service in between to be as simple as possible, and decided to take the RESTful approach. My problem is that I know our application will grow substantially in the future, and writing all the getters, setters, serialization, factories, etc. by hand fills me with absolute dread. So in order to avoid it, I decided to implement annotations to keep track of attributes on the models. The reason I can't just serialize everything directly, using GWT's own one, or one which works through reflection, is because we need a certain amount of logic going on in the serialization process. I.e. whether references to other models get serialized during the serialization of the original model, or whether an ID is just passed, and general simple things like that. I've then written an annotation processor to preprocess my shared models and generate an implementing class with all the getters, setters, serialization, lazy-loading, etc. To make a long story short, I need some type of simple YAML or JSON library, which allows me to encode and decode manually, so I can generate this code through my annotation processor. I have had a look around the interwebs, but every single one I ran into supported some reflection which, while all fine and dandy, make it pretty much useless for GWT. And in the case of GWT's own JSON library, it uses JSNI for speed purposes, making it useless server side. One solution I did think about involved writing writing two sets of serialization methods on the models, one for the client and one for the server, but I'd rather not do that. Also, I'm pretty new to GWT, and even though I have done a lot of Java, it was back in the 1.2 days, so it's a bit rusty. So if you think I'm going about this problem completely the wrong way, I'm open to suggestions.

  • Smart Client App: How to give Different Settings for Different Users

    - by Daniel
    Hi! I have a smart client application being deployed with a CickOnce webpage. here's the current scenario. User runs the application, and the application shows a login form. User enters ID/Password in the login form, and the application sends that information to the server. The server authenticates the user and sends configuration and data to the application. Different users have different configuration and data for their application. I was concerned that anyone can download the application from the webpage if they know the URL. So I'm trying to change the authentication scheme, so that users can login at the webpage to download the application. I want to send the authentication info from the webpage(Program running at the server) to the smart client app, so that application can download the configuration information from the server, without prompting users to make a login again. How can the webpage send the ID/Passoword to the application securely?

  • InvalidOperationException when using soap client

    - by codymanix
    I've added as wsdl file using the add servece reference dialog in vs2008. MyService serviceproxy = new MyService(); When I instantiate the service proxy, I get an InvalidOperationException with the following text (translated from german): Could not find default endpoint element to the contract "ServiceName.ServiceInterface" in the service model refers client configuration section. This may be because: The application configuration file was not found or not an endpoint in the client element item is found, which corresponded to this contract. Where servicename is the name I give the service when I add it in vs2008 and ServiceInterface the interface which is automatically generated for it.

  • SharePoint Client JavaScript Documentation

    - by G N
    I'm attempting to improve the usability of a client's SharePoint deployment via JQuery; and am hitting a brick wall when trying to find any sort of documentation of what's happening in core.js (aside from painfully digging through and trying to parse any sort of meaning out of it --all 250kb of it!!!!--) Anyone have any pointers, or documentation? EDIT: Sorry, to clarify my question, i'm familiar with using JQuery with SharePoint. My question involves hooking JQuery into SharePoint's own client API. My question is inspired by this post http://www.codefornuts.com/2009/09/forcing-sharepoint-into-asynchronous.html# ; where the author is overriding methods such as "SubmitFormPost" and "STSNavigate" in order to make the UI interaction more "AJAXy".

  • How to Communicate between minifb and a GAE-Hosted Silverlight Client

    - by Nick Gotch
    I have a minifb app (technically gminifb) running on Google App Engine with a bunch of handlers for processing all kinds of requests from a Silverlight client. What's the recommended approach for adding the FB GET variables, such as fb_sig, to the HTTP requests? I believe I can technically pass the session key and uid directly and get things to work but it seems there's probably a much better way to do this. I was reading about FBJS AJAX and I'm trying to figure out how I can use it to proxy the HTTP requests from the Silverlight client through it. Is this a good way to do it? And if so, how would I go about doing so? Any other recommendations would be appreciated too. Thanks,

  • Writing html tags in GWT client side

    - by arinte
    I have this code in my gwt client side: String out = result.getConsoleOutput().replaceAll("\n", "<br/>"); transOut.getElement().setInnerText(out); Basically what comes out of consoleoutput() is text from a telnet client and transOut is a HTMLPanel in a UiBinder. I want it to show up pretty so I tried to change all the \n to html , but when it shows up in firefox it looks like this on screen blah blahblah blah.... I am guessing gwt escapes the text somewhere how can I get it to write the real tag.

  • Advantages of using a Dynamic Client with JAX-WS

    - by jconlin
    What are the advantages of using a dynamic client with JAX-WS services as opposed to just using generated client classes? What are the disadvantages? **For my particular case I am using Apache CXF, I'm not sure what other libraries allow "dynamic" clients. -I thought I didn't need to add this, but... I'm looking for non-obvious(I know...subjective) advantages. I don't need someone else to tell me that an advantage of not using generated classes is that I don't need to generate classes.

  • SOAP: JWSDP Webservice and Axis2 Client?

    - by Sophomore
    Just a plain simple question to which I could'nt find a straight answer... I'm building a SOAP webservice which is supposed to deliver some data to a client. (Actually it's RDF parsed/stripped to XML)... I'd like to use JWSDP which will generate WDSL specification. Are there any downfalls when the client is using axis2 instead of JWSDP? My intention was, that this shouldn't matter, as this is what WSDL is meant for, but I wanted to check before there arise any incompatibilities or problems...

  • Client or server side invocation to google API?

    - by Raffo
    I'm writing a web application with GWT and I've to call google calendar's API to retrieve some information. I now have this dilemma: Is it better to use a client side invocation (using javascript or gwt-gdata library) or using the standard google library for java to call the service at server side and then passing all the data to the client via an async call?? I'm not able to understand pros and cons of the two approaches... In particular, I need to call several time the calendar API to retrieve events and let users add new ones, etc. Can you help me?

  • Why does WebSharingAppDemo-CEProviderEndToEnd sample still need a client db connection after scope c

    - by Don
    I'm researching a way to build an n-tierd sync solution. From the WebSharingAppDemo-CEProviderEndToEnd sample it seems almost feasable however for some reason, the app will only sync if the client has a live SQL db connection. Can some one explain what I'm missing and how to sync without exposing SQL to the internet? The problem I'm experiencing is that when I provide a Relational sync provider that has an open SQL connection from the client, then it works fine but when I provide a Relational sync provider that has a closed but configured connection string, as in the example, I get an error from the WCF stating that the server did not receive the batch file. So what am I doing wrong? SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(); builder.DataSource = hostName; builder.IntegratedSecurity = true; builder.InitialCatalog = "mydbname"; builder.ConnectTimeout = 1; provider.Connection = new SqlConnection(builder.ToString()); // provider.Connection.Open(); **** un-commenting this causes the code to work** //create anew scope description and add the appropriate tables to this scope DbSyncScopeDescription scopeDesc = new DbSyncScopeDescription(SyncUtils.ScopeName); //class to be used to provision the scope defined above SqlSyncScopeProvisioning serverConfig = new SqlSyncScopeProvisioning(); .... The error I get occurs in this part of the WCF code: public SyncSessionStatistics ApplyChanges(ConflictResolutionPolicy resolutionPolicy, ChangeBatch sourceChanges, object changeData) { Log("ProcessChangeBatch: {0}", this.peerProvider.Connection.ConnectionString); DbSyncContext dataRetriever = changeData as DbSyncContext; if (dataRetriever != null && dataRetriever.IsDataBatched) { string remotePeerId = dataRetriever.MadeWithKnowledge.ReplicaId.ToString(); //Data is batched. The client should have uploaded this file to us prior to calling ApplyChanges. //So look for it. //The Id would be the DbSyncContext.BatchFileName which is just the batch file name without the complete path string localBatchFileName = null; if (!this.batchIdToFileMapper.TryGetValue(dataRetriever.BatchFileName, out localBatchFileName)) { //Service has not received this file. Throw exception throw new FaultException<WebSyncFaultException>(new WebSyncFaultException("No batch file uploaded for id " + dataRetriever.BatchFileName, null)); } dataRetriever.BatchFileName = localBatchFileName; } Any ideas?

  • <jaxrs:client> not getting autowired

    - by himangshu
    I am trying to build a restful client using jaxrs:client as defined in http://svn.apache.org/repos/asf/cxf/trunk/systests/jaxrs/src/test/resources/jaxrs_soap_rest/WEB-INF/beans.xml In my test class I am getting org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.abc.service.ExportServiceTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.bankbazaar.service.ExportService com.abc.service.ExportServiceTest.exportClient; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.abc.service.ExportService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true), @org.springframework.beans.factory.annotation.Qualifier(value=exportClient)} this is my spring config However exportClient=(ExportService)applicationContext.getBean("exportClient"); this works.

  • In a client-server relationship, should the server always rethrow the exception to the client?

    - by dotnetdev
    I have a set of web services (the server), and an app which consumes this (client). In this sort of relationship, should the server always throw exceptions (ie in the throw block, rethrow the caught exception), and the client catch this. Exceptions which the server can handle, it will deal with and not rethrow, but everything else will be thrown to the calling layer for further action (the consuming app can raise a msg box or whatever). Is this a good example of an exception that can be dealt with: A file cannot be written because the directory requires special privileges, so if this raises an exception, the file is written somewhere which does not require admin rights. Thanks

  • Pre-load audio files at the client-side for later use

    - by awj
    I'm building an online test which implements audio (mp3) using the native audio player (i.e. non Flash-based). The test shows one question at a time and loads each subsequent question asynchronously. Some questions have an accompanying audio file, others don't, and the audio files can be several MB in size. So what I'm hoping to do is to preload the audio files client-side at the start of the test and then move these into place when the relevant question comes up. So far I've tried loading an audio file into a QuickTime player, then when that question comes up I use jQuery's clone(true) method to copy this into a part of the page which is displayed. However, when I do this the QuickTime player has to reload the audio file from source. Same is true for Windows Media Player. Does anyone have any suggestions as to how I can preload the audio client-side and then call it forward when needed?
