• Parsing a list of dictionaries passed as a POST parameter

  - by andyashton

  I have a list of python dictionaries that look like this: sandwiches = [ {'bread':'wheat', 'topping':'tomatoes', 'meat':'bacon'}, {'bread':'white', 'topping':'peanut butter', 'meat':'bacon'}, {'bread':'sourdough', 'topping':'cheese', 'meat':'bacon'} ] I want to pass this as a POST parameter to another Django app. What does the client app need to do to iterate through the list? I want to do something like: for sandwich in request.POST['sandwiches']: print "%s on %s with %s is yummy!" % (sandwich['meat'], sandwich['bread'], sandwich['topping']) But I don't seem to have a list of dicts when my data arrives at my client app.

• How to point to jdni.properties file to set properties in Java

  - by prosseek

  I can use System.getProperties() method to set properties in Java. System.getProperties().put("java.naming.factory.initial", "fr.dyade.aaa.jndi2.client.NamingContextFactory"); System.getProperties().put("java.naming.factory.host", "localhost"); System.getProperties().put("java.naming.factory.port", "16400"); How can I get the same effect by reading the properties stored in a file? When I have a jdni.properties with the following content: java.naming.factory.initial fr.dyade.aaa.jndi2.client.NamingContextFactory java.naming.factory.host localhost java.naming.factory.port 16400 How can I teach Java to read them as properties?

• Silverlight 4 launch a trusted application into the browser ?

  - by Niklaos

  Hi guys, I just lost 5 hours looking for a answer which i haven't been able to find :p First, I'd like to force a trusted application (i need to access the file system) to display into the browser. Based on what i found on google a trusted application must be installed and launched as a desktop application (also called out-of-browser application). So, i want to have an installed application on the client side but meanwhile, the user must also be able to start this same application into a browser window when he goes on my web site. Is this possible ? Second, I'd like to give to the user the possibility to start the application from the browser. To be clear be the application is installed on the client computer but i want a button on my web site which starts the desktop application. How can i do that ? Thanks

• Reliable session faulting for unknown reason

  - by Scarfman007

  I am trying to achieve the following - one client-side proxy instance (kept open) accessed by multiple threads using a reliable session. What I have managed so far is to have either A) a reliable session with a client-side proxy which is created and disposed per call or B) what I aim for, but without a reliable session. When I enable reliable sessions on my binding however, the following behaviour is exhibited: Client-side Upon application startup everything appears to work fine until roughly 18 messages in to the WCF session. I firstly get the proxy.InnerChannel.Faulted event raised, then an exception is caught at the point where I am calling the method on the proxy. The exception is a System.TimeoutException, with message: "The request channel timed out while waiting for a reply after 00:00:59.9062512. Increase the timeout value passed to the call to Request or increase the SendTimeout value on the Binding. The time allotted to this operation may have been a portion of a longer timeout." The inner exception has a similar message: "The request operation did not complete within the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout." With the method at the top of the inner stack trace being: System.ServiceModel.Channels.ReliableRequestSessionChannel.SyncRequest.WaitForReply(TimeSpan timeout) I then call proxy.Close followed by proxy.Abort (catching and ignoring exceptions). If I utilize the default settings (i.e. have simply <reliableSession/>), then calling proxy. Close results in another System.Timeout exception (although this time the allotted timeout is 00:00:00), however if I override the defaults as specified above no exception is thrown. Service-side Utilizing WCF tracing I get a System.ServiceModel.CommunicationException, with message: "The sequence has been terminated by the remote endpoint. The session has stopped waiting for a particular reply. Because of this the reliable session cannot continue. The reliable session was faulted." And a stack trace ending at: System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result) When remotely attaching to the server I get the same message, which occurs when code execution steps over the return statement of my service in the service call which causes the error. The puzzling thing to me is that the service is stable and runs with options A) or B) as decribed at the beginning of my post, and occurs after a varying number of messages (around 18). The former fact points to there being nothing wrong with the code (indeed I have checked that no exceptions are thrown), and the latter just serves to confuse me and is why I modified the settings on the reliable session binding. I am quite stuck on this. Can anyone suggest why the reliable session would fault in such a way?

• How to recive more than 65000 bytes in C++ socket using recv()

  - by Mr.Cool

  I am developing a client server application (TCP) in Linux using C++. I want to send more than 65,000 bytes at the same time. In TCP, the maximum packet size is 65,635 bytes only. How can I send the entire bytes without loss? Following is my code at server side. //Receive the message from client socket if((iByteCount = recv(GetSocketId(), buffer, MAXRECV, MSG_WAITALL)) > 0) { printf("\n Received bytes %d\n", iByteCount); SetReceivedMessage(buffer); return LS_RESULT_OK; } If I use MSG_WAITALL it takes a long time to receive the bytes so how can I set the flag to receive more than 10 lakhs bytes at time.

• How can I convert arbitrary strings to CLS-Compliant names?

  - by Brian Hinchey

  Does anyone know of an algorithm (or external library) that I could call to convert an arbitrary string (i.e. outside my control) to be CLS compliant? I am generating a dynamic RDLC (Client Report Definition) for an ASP.Net Report Viewer control and some of the field names need to be based on strings entered by the user. Unfortunately I have little control over the entry of the field names by the client (through a 3rd party CMS). But I am quite flexible around substitutions required to create the compliant string. I have a reactive hack algorithm for now along the lines of: public static string FormatForDynamicRdlc(this string s) { //We need to change this string to be CLS compliant. return s.Replace(Environment.NewLine, string.Empty) .Replace("\t", string.Empty) .Replace(",", string.Empty) .Replace("-", "_") .Replace(" ", "_"); } But I would love something more comprehensive. Any ideas? NOTE: If it is of any help, the algorithm I am using to create the dynamic RDLC is based on the BuildRDLC method found here: http://csharpshooter.blogspot.com/2007/08/revised-dynamic-rdlc-generation.html

• Is it possible to have an out-of-process COM server where a separate O/S process is used for each ob

  - by Tom Williams

  I have a legacy C++ "solution engine" that I have already wrapped as an in-process COM object for use by client applications that only require a single "solution engine". However I now have a client application that requires multiple "solution engines". Unfortunately the underlying legacy code has enough global data, singletons and threading horrors that given available resources it isn't possible to have multiple instances of it in-process simultaneously. What I am hoping is that some kind soul can tell me of some COM magic where with the flip of a couple of registry settings it is possible to have a separate out-of-process COM server (separate operating system process) for each instance of the COM object requested. Am I in luck?

• Detecting/Repairing NSConnection failure

  - by anthony

  I would like to use NSConnection/NSDistributedObject for interprocess communication. I would like the client to be able to handle the case where the server is only occasionally reachable. How can I determine if sending a message to the NSConnection will fail or has failed? Currently if my server (the process that has vended the remote object) dies, the client will crash if it sends a selector to the remote object. Ideally I'd like to have a wrapper for the remote object that can lazily instantiate (or reinstantiate) the connection, and return a default value in the case where the connection could not be instantiated, or the connection has failed. I don't really know the correct way to do this using objective c. Here's some pseudocode representing this logic: if myConnection is null: instantiate myConnection if MyConnection is null: return defaultValue try return [myConnection someMethod] catch myConnection = null return defaultValue

• Move namespace declaration from payload to envelope on an axis created web service

  - by rmarimon

  I just created a web service client using axis and eclipse that does not work with my web service provider. The message created by the web service client looks like this: <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <soapenv:Body> <enviarMensajeRequest xmlns="http://www.springframework.org/spring-ws/Imk-Zenkiu-Services"> <usuario>someuser</usuario> <clave>somepassword</clave> <mensaje>somemessage</mensaje> <contacto> <buzonSMS>somenumber</buzonSMS> <primerNombre>somefirstname</primerNombre> <primerApellido>somelastname</primerApellido> </contacto> </enviarMensajeRequest> </soapenv:Body> </soapenv:Envelope> I see nothing wrong with the message but my provider insists the message should be: <?xml version="1.0" encoding="UTF-8"?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:imk="http://www.springframework.org/spring-ws/Imk-Zenkiu-Services"> <soapenv:Body> <imk:enviarMensajeRequest> <imk:usuario>someuser</imk:usuario> <imk:clave>somepassword</imk:clave> <imk:mensaje>somemessage</imk:mensaje> <imk:contacto> <imk:buzonSMS>somenumber</imk:buzonSMS> <imk:primerNombre>somefirstname</imk:primerNombre> <imk:primerApellido>somelastname</imk:primerApellido> </imk:contacto> </imk:enviarMensajeRequest> </soapenv:Body> </soapenv:Envelope> Notice the namespace declaration moving from the enviarMensajeRequest to the soapenv:Envelope and the qualification with imk: on the parameters. I've tried many combinations on the process but my web service, wsdl and xml knowledge is very limited. The provider says that they can't help beyond telling me this. Any ideas? Perhaps a different framework that I can use to create the correct client.

• What alternatives are there in OS projects for c# similar to Joomla/Mambo/Drupal?

  - by Joseph

  I'm beginning a project with a client to build a web application and I'm a little stuck on which solution to go with. I've used Joomla for many clients in the past, but this client has specific requests that I KNOW I'm going to have to build myself. The problem I'm facing is that I work full time under the .NET spectrum and while I am a novice developer in PHP, and I've been studying Joomla's plug in architecture for about a month now, I am a lot more comfortable building something in ASP.NET than I am in PHP. My question is, what OS projects are out there that have a similar community following as Joomla/Mambo/Drupal, along with a plug in architecture that is somewhat akin to Joomla as well? I don't really have the time to build out a full blown CMS system in ASP.NET, but if something already exists that can give me X% (25%, 50%, something) of what Joomla has that will at least get me on the right path. Joomla just has too many extensions and too much of a community backing for me to pass it up if there's not something comparable in the ASP.NET realm.

• IP address problem

  - by mavric

  I built a TicTacToe game application (I'm using TCP protocol) that consist of server and client (that run two times to represent the 2 opponents). I have a problem and I can't find the solution for it, that is why I'm asking this question. the problem is : when the client try to connect the server on my machine, it never connect because of the IP address(obtained from the support tab from the local area connection in my windows) of my machine isn't correct. I tried to obtain my IP address from websites that told you your IP but I doesn't work. I have a problem to determine my IP address that any machine can connect to me from anywhere. p.s. I'm using router to connect the internet. thanks.

• How do I assign a non-persistent (in-memory) cookie in ASP.NET?

  - by Jørn Schou-Rode

  The following code will send a cookie to the user as part of the response: var cookie = new HttpCookie("theAnswer", "42"); cookie.Expires = DateTime.Now.AddDays(7); Response.Cookies.Add(cookie); The cookie is of the persistent type, which by most browsers will be written to disk and used across sessions. That is, the cookie is still on the client's PC tomorrow, even if the browser and the PC has been closed in between. After a week, the cookie will be deleted (due to line #2). Non-persistent/in-memory cookies are another bread of cookies, which have a lifespan determined by the duration of the client's browsing session. Usually, such cookies are held in memory, and they are discarded when the browser is closed. How do I assign an in-memory cookie from ASP.NET?

• RST packet sent by the server

  - by intoTHEwild

  I am developing a client in Flash and using http req/resp to communicate with the server. For a while the session works fine and then the connection is terminated by the server. I did a wireshark sniff at the server and the last message which it sends is a RST packet. Also it happens only when I'm using IE and the server and client are in different domains. This does not happen in FireFox. I have been struggling to find a sol, till I found this thread. It's a bit old but I hope I could get some help. I am not sure if this bit of info is important but I am connecting to the server via a gateway. Any clue or suggestions for where should I look into to locate the problem ?

• Detecting regional settings (List Separator) from web

  - by Toms Mikoss

  After having the unpleasant surprise that Comma Seperated Value (CSV) files are not necessarily comma-separated, I'm trying to find out if there is any way to detect what the regional settings list separator value is on the client machine from http request. Scenario is as follows: A user can download some data in CSV format from web site (RoR, if it matters). That CSV file is generated on the fly, sent to the user, and most of the time double-clicked and opened in MS Excel on Windows machine at the destination. Now, if the user has ',' set as the list separator, the data is properly arranged in columns, but if any other separator (';' is widely used here) is set, it all just gets thrown into a single column. So, is there any way to detect what separator is used on the client machine, and generate the file accordingly? I have a sinking feeling that it is not, but I'd like to be sure before I pass the 'can't be done, sorry' line to the customer :)

• Do not use IE browser settings when using a proxy with Indy

  - by JD

  Hi At one of our customer sites, we have a Delphi 2007 application that makes a number of HTTPS requests using indy components. All requests are made using the proxy settings the client provides. For this to work, in IE we have to put the URL's in the trusted zones section. After a month due to security settings the trusted zones are cleared. This means we have to re-add the URLs again to make our application work. Is there a way of bypassing IE settings or using a client side HTTP stack so we do not go through the browser to make https requests? JD

• Socket programming and telnet with VB.net

  - by Mike

  I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy. So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API? Does Mono have something like this? Barring an easy solution, does anyone have a good tutorial they can point to for telnet client programming in VB.net?

• What is the best practice for mvc2 confirm password field?

  - by Andrey

  I have asked a similar question recently but getting no answers i am taking a step back with a more broad approach. I am looking to create a confirm password field using asp.net MVC2 that works on the client. All my other client validation is done with MicrosoftMvcValidation.js by just adding the Html.EnableClientValidation(); call. Some of my considerations. Should the confirm password be part of the model object? Using that approach i have created server side validation by creating my own model binder. Are there any projects out there that have done this?

• Designing a service for consumption on multiple mobile platforms

  - by Nate Bross

  I am building and designing a (mostly) read-only interface to some data. I'll be uing ASP.NET MVC to build a psudo-restful API. I'm wondering if anyone can provide some resources for building full-client applications for various mobile platforms, iPhone, Android, Blackberry, Windows Mobile, etc. I'm thinking that serving up XML data is going to be the most simple and universal, but parsing XML in objective-C for example doesn't sound like fun to me, but maybe there are some good libaries out there to help ease this task? In other words, what formt will be the quickest to implement on the client side? Are there any JSON parsrs for iPhone or Android? I know there are .NET JSON parsers, but not sure about other platforms -- is ther another format that might better? Or should I stick with pure XML and deal with it on each platform differently?

• How to ensure that a Serialized object is completely read over a Socket ?

  - by Amitd

  Hi guys, I am trying to write a socket server and Client that communicate with each other via serialized Objects.eg:To Login, Client sends server a serialized Login object and then the server deserialises the object to read login details. Similarly for other types of request/response. I just wanted to be sure if Socket.receive() can read(untill) large serialized objects completely. I have tried this code but seems to fail when a large object is serialised and sent over the internet.(seems to work fine in LAN situations.) http://stackoverflow.com/questions/2134356/sending-large-serialized-objects-over-sockets-is-failing-only-when-trying-to-grow using(MemoryStream ms = new MemoryStream()) { int bytesRead; while((bytesRead = m_socClient.Receive(buffer)) > 0) { ms.Write(buffer, 0, bytesRead); } // access ms.ToArray() or ms.GetBuffer() as desired, or // set Position to 0 and read } Are there any other ways to ensure that the object gets completely read.

• Is it actually possible to connect to ActiveMQ via XMPP and query/browse queues using "AciveMQ.Agen

  - by Oleg Kiorsak

  I tried what I think are 4 most popular XMPP (aka "Jabber") clients (Spark, Pidgin, Psi, Pandion) to connect to ActiveMQ instance (Apache ActiveMQ ver. 5.3.0) on XMMP connector with an idea to use the "AciveMQ.Agent chatroom" for querying queues/etc and no success at all Some of them fail with 'Unknown error', some don't fail but kind of "hang"... interestingly, some communication does indeed reach the ActiveMQ side, because when I close a client it spits an exception "could not close" or something to that effect... and if I try "register new user" option (present on most clients" the ActiveMQ also spits some most cryptic warning message But I was never able to get to the point when I could see or specify "ActiveMQ.Agent" as chatroom and issue any commands... Before I waste any more time on this curious feature, I would like to hear whether anyone had any success with it? Thank you! PS: BTW, the book "ActiveMQ in Action book" http://www.manning.com/snyder/ shows that it is apparently works and is very easy using some Mac client (AdiumX), but I wanted it on a Windows PC ;)
