  • Python inter-computer communication.

    - by matt1024
    This whole topic is way out of my depth, so forgive my imprecise question, but I have two computers both connected to one LAN. What I want is to be able to communicate one string between the two, by running a python script on the first (the host) where the string will originate, and a second on the client computer to retrieve the string. What is the most efficient way for an inexperienced programmer like me to achieve this?

    - by pirates-iiita
    We use socket.send(packet) function in java to send a "packet" to a given port. My problem is that i have to send a packet to a shutdown system using UDP protocol. The problem with send() function is that first it verifies whether the host IP is multicast or not. Now my local area network is of broadcast type. So i am having problem is using this function. can anyone please give me a way ?

  • Are NHibernate lists loaded on demand?

    - by André Pena
    This is a pretty simple question. When I do this: session.CreateCriteria(typeof(Product)).List(); The resulting list will load as I access it? Let's say, from 100 to 100 elements for example? Or will it load all once? In the case it's not "virtual" how can I make it so? What's the best pratice about it? Thanks;

  • state server session - cross appDomain?

    - by newone1
    When using a State server for session, are sessions still appDomain specific? So for example, I have two different IIS applications(virtual directories) on a web server, and they both point to one state server for session. The session guid from the cookie will be the same across requests from both applications, so will the same session be accessible across both of these applications? Thanks.

  • Is It Possible to Make Close Sourced PHP Product?

    - by Morgan Cheng
    I'm curious that whether all PHP product must be open sourced if it is to be deployed to other's web site. Since PHP code is executed by interpretation, if I have PHP product to be deployed on other's host, it seems no reason to prevent others view the source code. So, PHP product is destined to be open source, right?

  • Maximum nametable char count exceeded

    - by doc
    I'm having issues with the maximum nametable char count quota, I followed a couple of answers here and it solved the problem for a while, but now I'm having the same issue. My Server side config is as follows: <system.serviceModel> <bindings> <netTcpBinding> <binding name="GenericBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> <security mode="None" /> </binding> </netTcpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior> <serviceMetadata httpGetEnabled="false" /> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="1000000" /> </behavior> </serviceBehaviors> </behaviors> <services> <service name="REMWCF.RemWCFSvc"> <endpoint address="" binding="netTcpBinding" contract="REMWCF.IRemWCFSvc" bindingConfiguration="GenericBinding" /> <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:9081/RemWCFSvc" /> </baseAddresses> </host> </service> </services> </system.serviceModel> I also have the same tcp binding on the devenv configuration. Have I reached the limit of contracts supported? Is there a way to turn off that quota? EDIT Error Message: Error: Cannot obtain Metadata from net.tcp://localhost:9081/RemWCFSvc/mex If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

There is an error in the XML document. The maximum nametable character count quota (16384) has been exceeded while reading XML data. The nametable is a data structure used to store strings encountered during XML processing - long XML documents with non-repeating element names, attribute names and attribute values may trigger this quota. This quota may be increased by changing the MaxNameTableCharCount property on the XmlDictionaryReaderQuotas object used when creating the XML reader. I'm getting that error when trying to run the WCF (which is hosted in a windows service app).

  • How to infer the type of a derived class in base class?

    - by enzi
    I want to create a method that allows me to change arbitrary properties of classes that derive from my base class, the result should look like this: SetPropertyValue("size.height", 50); – where size is a property of my derived class and height is a property of size. I'm almost done with my implementation but there's one final obstacle that I want to solve before moving on, to describe this I will first have to explain my implementation a bit: Properties that can be modified are decorated with an attribute There's a method in my base class that searches for all derived classes and their decorated properties For each property I generate a "property modifier", a class that contains 2 delegates: one to set and one to get the value of the property. Property Modifiers are stored in a dictionary, with the name of the property as key In my base class, there is another dictionary that contains all property-modifier-dictionaries, with the Type of the respective class as key. What the SetPropertyValue method does is this: Get the correct property-modifier-dictionary, using the concrete type of the derived class (<- yet to solve) Get the property modifier of the property to change (e.g. of the property size) Use the get or set delegate to modify the property's value Some example code to clarify further: private static Dictionary<RuntimeTypeHandle, object> EditableTypes; //property-modifier-dictionary protected void SetPropertyValue<T>(EditablePropertyMap<T> map, string property, object value) { var property = map[property]; // get the property modifier property.Set((T)this, value); // use the set delegate (encapsulated in a method) } In the above code, T is the Type of the actual (derived) class. I need this type for the get/set delegates. The problem is how to get the EditablePropertyMap<T> when I don't know what T is. My current (ugly) solution is to pass the map in an overriden virtual method in the derived class: public override void SetPropertyValue(string property, object value) { base.SetPropertyValue((EditablePropertyMap<ExampleType>)EditableTypes[typeof(ExampleType)], property, value); } What this does is: get the correct dictionary containing the property modifiers of this class using the class's type, cast it to the appropiate type and pass it to the SetPropertyValue method. I want to get rid of the SetPropertyValue method in my derived class (since there are a lot of derived classes), but don't know yet how to accomplish that. I cannot just make a virtual GetEditablePropertyMap<T> method because I cannot infer a concrete type for T then. I also cannot acces my dictionary directly with a type and retrieve an EditablePropertyMap<T> from it because I cannot cast to it from object in the base class, since again I do not know T. I found some neat tricks to infere types (e.g. by adding a dummy T parameter), but cannot apply them to my specific problem. I'd highly appreciate any suggestions you may have for me.

  • C++ class member functions instantiated by traits

    - by Jive Dadson
    I am reluctant to say I can't figure this out, but I can't figure this out. I've googled and searched Stack Overflow, and come up empty. The abstract, and possibly overly vague form of the question is, how can I use the traits-pattern to instantiate non-virtual member functions? The question came up while modernizing a set of multivariate function optimizers that I wrote more than 10 years ago. The optimizers all operate by selecting a straight-line path through the parameter space away from the current best point (the "update"), then finding a better point on that line (the "line search"), then testing for the "done" condition, and if not done, iterating. There are different methods for doing the update, the line-search, and conceivably for the done test, and other things. Mix and match. Different update formulae require different state-variable data. For example, the LMQN update requires a vector, and the BFGS update requires a matrix. If evaluating gradients is cheap, the line-search should do so. If not, it should use function evaluations only. Some methods require more accurate line-searches than others. Those are just some examples. The original version instantiates several of the combinations by means of virtual functions. Some traits are selected by setting mode bits that are tested at runtime. Yuck. It would be trivial to define the traits with #define's and the member functions with #ifdef's and macros. But that's so twenty years ago. It bugs me that I cannot figure out a whiz-bang modern way. If there were only one trait that varied, I could use the curiously recurring template pattern. But I see no way to extend that to arbitrary combinations of traits. I tried doing it using boost::enable_if, etc.. The specialized state information was easy. I managed to get the functions done, but only by resorting to non-friend external functions that have the this-pointer as a parameter. I never even figured out how to make the functions friends, much less member functions. The compiler (VC++ 2008) always complained that things didn't match. I would yell, "SFINAE, you moron!" but the moron is probably me. Perhaps tag-dispatch is the key. I haven't gotten very deeply into that. Surely it's possible, right? If so, what is best practice?

  • What causes POCO proxy entities to only sometimes be created in Entity Framework 4.

    - by Kohan
    I have set up my POCOs and I have marked their public properties as virtual and I am successfully getting Proxies most of the time (95%) but randomly I am getting EF return some proxies and some non-proxies. Recycling the app pool when this happens will then fix this instance of the error and it will go away for an amount of time. Then it will re-occur in some other random (it seems) place. What can cause this sort of behaviour? Thanks, Kohan

  • How to kill locked mysql queries

    - by jcure
    Hi, I am creating and testing a mysql join query but each time so far it causes the database tables to lockup and the site hangs. I have to then call the host and they kill the locked queries. Is this something I can do from phpmyadmin so not to bother them while I tweak the script to work? Thanks for any reply.

  • How do I diagnose a failure in the Membership service on an ASP.NET remote site?

    - by ProfK
    Yesterday I added a custom MembershipProvider to an ASP.NET web application, but when I deployed the application to its remote host server, it failed. I know I had the login info correct, and I also know that for nearly any exception in the login process, the Login control displays the standard error message, "Your login failed", so I assume something is wrong in the code/config. What can I do to diagnose what is wrong on the server?

  • Hosting MSMQ Integration Binding with WAS

    Appears that WAS does not support the integration binding. I've tried setting it up by enabling the net.msmq protocol in WAS just to confirm it to no avail. Has anyone gotten this to work and if not, what are you using to host integration services? I'm leaning towards a Windows Service.

  • debug=true in web.config = BAD thing?

    - by MateloT
    We're seeing lots of virtual memory fragmentation and out of memory errors and then it hits the 3GB limit. The compilation debug is set to true in the web.config but I get different answers from everyone i ask, does debug set to true cause each aspx to compile into random areas of ram thus fragmenting that ram and eventually causing out of memory problems?
