  • Efficient process SQL Server and numerical methods library

    - by darkcminor
    Is there a way to comunicate a numeric method library, that can exploit all .net's (numerical methods called by .net that does SQL Server things) habilities?, What library do you recomend, maybe using MATLAB, R? How to comunicate SQL Server and .net with such library or libraries? Do you have an example? What steps must be followed to make the link between numerical libraries, .net and SQL Server

  • Python c_types .dll functions (pari library)

    - by silinter
    Alright, so a couple days ago I decided to try and write a primitive wrapper for the PARI library. Ever since then I've been playing with ctypes library in loading the dll and accessing the functions contained using code similar to the following: from ctypes import * libcyg=CDLL("<path/cygwin1.dll") #It needs cygwin to be loaded. Not sure why. pari=CDLL("<path>/libpari-gmp-2.4.dll") print pari.fibo #fibonacci function #prints something like "<_FuncPtr object at 0x00BA5828>" So the functions are there and they can potentially be accessed, but I always recieve an access violation no matter what I try. For example: pari.fibo(5) #access violation pari.fibo(c_int(5)) #access violation pari.fibo.argtypes=[c_long] #setting arguments manually pari.fibo.restype=long #set the return type pari.fibo(byref(c_int(5))) #access violation reading 0x04 consistently and any variation on that, including setting argtypes to receive pointers. The Pari .dll is written in C and the fibonacci function's syntax within the library is GEN fibo(long x) (docs @http://pari.math.u-bordeaux.fr/dochtml/html/Arithmetic_functions.html#fibonacci, I need more rep it seems). Could it be the return type that's causing these errors, as it is not a standard int or long but a GEN type, which is unique to the PARI library? Any help would be appreciated. If anyone is able to successfully load the library and use ANY function from within python, please tell; I've been at this for hours now.

  • Calling COM Library From XBAP

    - by Benny
    I am trying to call an old COM library from my XBAP and continue to receive the following exception: System.AccessViolationException was unhandled Message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I have tried adding the HKLM value for RunUnrestricted to no avail. I don't get anything else but this error when calling the library. Any ideas? (This library even works from a pure ASP.NET app)

  • Is it possible to use XStream with an abstract node?

    - by Dan Watling
    My client application is making calls to a service that returns a common "root" XML, but a different result node. The "root" XML contains possible error codes. Is it possible to use XStream in this scenario? Example: public class RootNode { ErrorInfo errorInfo; BaseResult result; ... } public class ErrorInfo { String message; ... } public abstract BaseResult { } public class SearchResult extends BaseResult { List<Object> searchResults; ... } public class AccountResult extends BaseResult { String name; ... } The XML coming back could be one of two formats: <root> <errorInfo><message>...</message></errorInfo> <result> <searchResults>...</searchResults> </result> </root> OR <root> <errorInfo><message>...</message></errorInfo> <result> <name>...</name> </result> </root> I have set up my XStream object as follows: XStream x = new XStream(); x.alias("root", Root.class); x.alias("errorInfo", ErrorInfo.class); x.alias("result", <SearchResult.class OR AccountResult.class depending on what I am expecting back>); Of course, when I run this I receive an error telling me XStream cannot instantiate the base class (BaseResult). For fun, I also converted the BaseResult into an interface but received a similar error. I've looked through XStream's documentation and it isn't clear to me how to handle a situation like the one I just described. Is it even possible to do using XStream? Thanks, -Dan

  • Connection string in app.config in a class library

    - by Copeleto
    I am creating solution and inside I have three projects: A WCF Service Library Project A DataAccess Project (Class Library) A Web site for hosting WCF service The implementation of the service is on the project # 1, but in order to access the DataBase I use a second project that implements the data access using a class library project. That problem is in order to get data access I need to configure a connection string, but that connection string must be configurable in a production environment, I meant in production I am going to deploy the site, which is a very simple project that contains only a reference WCF Service Library Project then a guy from database department will configure the connection string. In development I have an app.config on the data access project but when I do the release that app.config is embedded on the dll. Any ideas how can we achieve our purpose

  • Refactoring a C# derived class with method dependancies

    - by drelihan
    Hi Folks, I want to get your opinion on this. I have a class which is derived from a base class. I don't have control over the code in the base class and it is critical to the system that I derive from it. In my class I inherite two methods that are critical to the system and are used in pretty much every function, many times. I intend to refactor this derived class and extract some classes from it - this won't be a problem. What I'm not sure about is, is it worth extracting class if I have to constantly make call backs to my main class to access the two methods (or public wrappers to the methods)??? Thanks

  • Flex Unit testing of library and mxml using FlexUnit

    - by user344722
    Hi, I have some software classes(library) to run commands on any mxml file. These classes(library) are wrapped in a SWC file. This SWC file is referenced by any sample mxml application (by adding as SWC file). My problem is that I want to test these software classes(library) against my sample mxml file using FlexUnit. That is, I should test methods run by software classes on the mxml file. How can I accomplish this? Thanks, Pradeep

  • WCF service with 2 Bindings and 2 Base Addresses

    - by Sean
    I have written a WCF service (I am a newb) that I want to provide 2 endpoints for (net.tcp & basicHttp) The problem comes when I try to configure the endpoints. If I configure them as seperate services, then my service names are the same which causes a problem. I have seen recomended creating shim classes (classA : MyService, and ClassB : MyService) but that seems smelly. <services> <service name="MyWcfService.MyService" behaviorConfiguration="MyWcfService.HttpBehavior"> <endpoint name="ApplicationHttp" address="Application" binding="basicHttpBinding" bindingConfiguration="HttpBinding" contract="MyWcfService.Interfaces.IMyService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8731/MyWcfService/" /> </baseAddresses> </host> </service> <service name="MyWcfService.MyService" behaviorConfiguration="MyWcfService.MyBehavior"> <endpoint name="Application" address="Application" binding="netTcpBinding" bindingConfiguration="SecuredByWindows" contract="EmsHistorianService.Interfaces.IApplicationHistorianService" /> <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:49153/MyWcfService" /> </baseAddresses> </host> </service> </services> I have tried using a single service with the base address integrated into the address, but that gives me errors as well <services> <service name="MyWcfService.MyService" behaviorConfiguration="MyWcfService.HttpBehavior"> <endpoint name="ApplicationHttp" address="http://localhost:8731/MyWcfService/Application" binding="basicHttpBinding" bindingConfiguration="HttpBinding" contract="MyWcfService.Interfaces.IMyService" /> <endpoint address="http://localhost:8731/MyWcfService/mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <endpoint name="Application" address="net.tcp://localhost:49153/MyWcfService/Application" binding="netTcpBinding" bindingConfiguration="SecuredByWindows" contract="EmsHistorianService.Interfaces.IApplicationHistorianService" /> <endpoint address="net.tcp://localhost:49153/MyWcfService/mex" binding="mexTcpBinding" contract="IMetadataExchange" /> </service> </services> Any ideas?

  • What's the best way to do base36 arithmetic in perl?

    - by DVK
    What's the best way to do base36 arithmetic in Perl? To be more specific, I need to be able to do the following: Operate on positive N-digit numbers in base 36 (e.g. digits are 0-9 A-Z) N is finite, say 9 Provide basic arithmetic, at the very least the following 3: Addition (A+B) Subtraction (A-B) Whole division, e.g. floor(A/B). Strictly speaking, I don't really need a base10 conversion ability - the numbers will 100% of time be in base36. So I'm quite OK if the solution does NOT implement conversion from base36 back to base10 and vice versa. I don't much care whether the solution is brute-force "convert to base 10 and back" or converting to binary, or some more elegant approach "natively" performing baseN operations (as stated above, to/from base10 conversion is not a requirement). My only 3 considerations are: It fits the minimum specifications above It's "standard". Currently we're using and old homegrown module based on base10 conversion done by hand that is buggy and sucks. I'd much rather replace that with some commonly used CPAN solution instead of re-writing my own bicycle from scratch, but I'm perfectly capable of building it if no better standard possibility exists. It must be fast-ish (though not lightning fast). Something that takes 1 second to sum up 2 9-digit base36 numbers is worse than anything I can roll on my own :) P.S. Just to provide some context in case people decide to solve my XY problem for me in addition to answering the technical question above :) We have a fairly large tree (stored in DB as a bunch of edges), and we need to superimpose order on a subset of that tree. The tree dimentions are big both depth- and breadth- wise. The tree is VERY actively updated (inserts and deletes and branch moves). This is currently done by having a second table with 3 columns: parent_vertex, child_vertex, local_order, where local_order is an 9-character string built of A-Z0-9 (e.g. base 36 number). Additional considerations: It is required that the local order is unique per child (and obviously unique per parent), Any complete re-ordering of a parent is somewhat expensive, and thus the implementation is to try and assign - for a parent with X children - the orders which are somewhat evenly distributed between 0 and 36**10-1, so that almost no tree inserts result in a full re-ordering.

  • Ubuntu: SWT App Can't Load GTK Library

    - by Nifty255
    I have supplied the Linux SWT jar and packaged my app in Eclipse to include swt.jar inside my app's jar. When I try to run it on Ubuntu, I get the following error text (posting only cause): Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-pi-gtk-4234 in java.library.path no swt-pi-gtk in java.library.path /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk-4234.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory Can't load library: /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk.so This indicates to me it can't load a GTK file, but anything beyond that, and I'm at a loss. I'm only using Ubuntu to test my app, so I know very little.

  • groovy call private method in Java super class

    - by Jeff Storey
    I have an abstract Java class MyAbstractClass with a private method. There is a concrete implementation MyConcreteClass. public class MyAbstractClass { private void somePrivateMethod(); } public class MyConcreteClass extends MyAbstractClass { // implementation details } In my groovy test class I have class MyAbstractClassTest { void myTestMethod() { MyAbstractClass mac = new MyConcreteClass() mac.somePrivateMethod() } } I get an error that there is no such method signature for somePrivateMethod. I know groovy can call private methods but I'm guessing the problem is that the private method is in the super class, not MyConcreteClass. Is there a way to invoke a private method in the super class like this (other than using something like PrivateAccessor)? thanks Jeff

  • Unit testing an iPhone static library with XCode 3

    - by teabot
    I am writing a number of static libraries for the iPhone and wish also to have suites of unit tests. XCode 3 provides templates for both static libraries and unit tests but I am wondering how they should fit together in a static library project? In my static library project I have created a target for unit testing but expect to also create an executable to kick off the unit tests than run against the classes in the static library. What is the procedure for doing this?

  • Polymorphic functions with parameters from a class hierarchy

    - by myahya
    Let's say I have the following class hierarchy in C++: class Base; class Derived1 : public Base; class Derived2 : public Base; class ParamType; class DerivedParamType1 : public ParamType; class DerivedParamType2 : public ParamType; And I want a polymorphic function, func(ParamType), defined in Base to take a parameter of type DerivedParamType1 for Derived1 and a parameter of type DerivedParamType2 for Derived2. How would this be done without pointers, if possible?

  • ActionScript: Type coercion problem with BlazeDS/AMF and class interfaces

    - by mike
    Hi, I've got a problem with type coercion in a Java/Hibernate/BlazeDS/Flex-Setup. First of all, my classes look like this: --- JAVA --- Interface I (Abstract) Class A implements I Class B extends A --- ActionScript --- Interface I Class A implements I Class B extends A I got RemoteClass-Meta-Tags in all ActionScript-Classes/Interfaces I, A and B. Package structure and Class/Interface names are exactly the same. Now here's the problem: My Java Service successfully retrieves objects of class B from my database via Hibernate. I got another class C which has a member property of interface type I, so it should be possible to assign an object of type B. But for some reason i get the following error message: TypeError: Error #1034: cannot convert Object@28b44a89 to package.name.I I checked the Java object type in the service and it is of type B and seems to be totally fine. Why can't the object of type B be assigned to a member variable of type I? This is driving me nuts. Thanks in advance.

  • How to generate Doctrine models/classes that extend a custom record class

    - by Shane O'Grady
    When I use Doctrine to generate classes from Yaml/db each Base class (which includes the table definition) extends the Doctrine_Record class. Since my app uses a master and (multiple) slave db servers I need to be able to make the Base classes extend my custom record class to force writes to go to the master db server (as described here). However if I change the base class manually I lose it again when I regenerate my classes from Yaml/db using Doctrine. I need to find a way of telling Doctrine to extend my own Base class, or find a different solution to a master/slave db setup using Doctrine. Example generated model: abstract class My_Base_User extends Doctrine_Record { However I need it to be automatically generated as: abstract class My_Base_User extends My_Record { I am using Doctrine 1.2.1 in a new Zend Framework 1.9.6 application if it makes any difference.

  • Nested namespaces, correct static library design issues

    - by PeterK
    Hello all, I'm currently in the process of developing a fairly large static library which will be used by some tools when it's finished. Now since this project is somewhat larger than anything i've been involved in so far, I realized its time to think of a good structure for the project. Using namespaces is one of those logical steps. My current approach is to divide the library into parts (which are not standalone, but their purpose calls for such a separation). I have a 'core' part which now just holds some very common typedefs and constants (used by many different parts of the library). Other parts are for example some 'utils' (hash etc.), file i/o and so on. Each of these parts has its own namespace. I have nearly finished the 'utils' part and realized that my approach probably is not the best. The problem (if we want to call it so) is that in the 'utils' namespace i need something from the 'core' namespace which results in including the core header files and many using directives. So i began to think that this probably is not a good thing and should be changed somehow. My first idea is to use nested namespaces as to have something like core::utils. Since this will require some heavy refactoring i want to ask here first. What do you think? How would you handle this? Or more generally: How to correctly design a static library in terms of namespaces and code organization? If there are some guidelines or articles about it, please mentoin them too. Thanks. Note: i'm quite sure that there are more good approaches than just one. Feel free to post your ideas, suggestions etc. Since i'm designing this library i want it to be really good. The goal is to make it as clean and FAST as possible. The only problem is that i will have to integrate a LOT of existing code and refactor it, which will really be a painful process (sigh) - thats why good structure is so important)

  • Constrain generic extension method to base types and string

    - by hitch
    I want to have an extension method for XElement/XAttribute that allows me to apply a "ValueOrDefault" logic - perhaps with various slightly different implementations: ValueOrNull, ValueOrDefault, NumericValueOrDefault (which validates if the value is numeric), but I want to constrain these methods so that they can only work with ValueTypes or String (i.e. it does not really make sense to use any other reference types. Is it possible to do this with one implementation of each method, or will I have to have one where the constraint is "Structure" and one where the constraint is "String" - if I combine Structure and String in the generic constraint, I get the error : 'Structure' constraint and a specific class type constraint cannot be combined. An example of the current method implementation is as follows: <Extension()> _ Public Function ValueOrDefault(Of T As {Structure})(ByVal xe As XElement, ByVal defaultValue As T) As T If xe Is Nothing or xe.Value = "" Then Return defaultValue End If Return CType(Convert.ChangeType(xe.Value, GetType(T)), T) End Function

  • Invalid character in a Base-64 string when Concatenating and Url encoding a string

    - by Rob
    I’m trying to write some encryption code that is passed through a Url. For the sake of the issue I’ve excluded the actual encryption of the data and just shown the code causing the problem. I take a salt value, convert it to a byte array and then convert that to a base64 string. This string I concatenate to another base64 string (which was previously a byte array). These two base64 strings are then Url encoded. Here’s my code... using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Security.Cryptography; using System.IO; using System.Web; class RHEncryption { private static readonly Encoding ASCII_ENCODING = new System.Text.ASCIIEncoding(); private static readonly string SECRET_KEY = "akey"; private static string md5(string text) { return BitConverter.ToString(new MD5CryptoServiceProvider().ComputeHash(ASCII_ENCODING.GetBytes(text))).Replace("-", "").ToLower(); } public string UrlEncodedData; public RHEncryption() { // encryption object RijndaelManaged aes192 = new RijndaelManaged(); aes192.KeySize = 192; aes192.BlockSize = 192; aes192.Mode = CipherMode.CBC; aes192.Key = ASCII_ENCODING.GetBytes(md5(SECRET_KEY)); aes192.GenerateIV(); // convert Ivector to base64 for sending string base64IV = Convert.ToBase64String(aes192.IV); // salt value string s = "maryhadalittlelamb"; string salt = s.Substring(0, 8); // convert to byte array // and base64 for sending byte[] saltBytes = ASCII_ENCODING.GetBytes(salt.TrimEnd('\0')); string base64Salt = Convert.ToBase64String(saltBytes); //url encode concatenated base64 strings UrlEncodedData = HttpUtility.UrlEncode(base64Salt + base64IV, ASCII_ENCODING); } public string UrlDecodedData() { // decode the url encode string string s = HttpUtility.UrlDecode(UrlEncodedData, ASCII_ENCODING); // convert back from base64 byte[] base64DecodedBytes = null; try { base64DecodedBytes = Convert.FromBase64String(s); } catch (FormatException e) { Console.WriteLine(e.Message.ToString()); Console.ReadLine(); } return s; } } If I then call the UrlDecodedData method I get a “Invalid character in a Base-64 string” exception. This is generated because the base64Salt variable contains an invalid character (I’m guessing a line termination) but I can’t seem to strip it off.
