interop

问题 Background: We are designing a physics app, that will do a lot of data analysis, but our focus is integrating physical electronic equipement. Basically I would like to be able to call root (it's a big data analysis library from CERN written in C++) library written in C++ library from Java. Basically ability to use ROOT classes from Java (and doing it without losing much time to code JNI wrappers) is a showstopper to us (if it will be hard, most probably we will be using Qt). I can think of

问题 We are inserting content controls programmatically in word document and we don't want to add actions to the undo stack of word. The only way that we found is to access the undo commandbar-combobox and to remove the items related to inserting content control action, we are using the code below : var commandBars = _wordDocument.CommandBars.Cast<CommandBar>(); var standardCommandBar = commandBars.First(bar => bar.Name.Equals("Standard")); CommandBarComboBox undoControl = standardCommandBar

问题 Actually there should be a straight forward answer to this question (is about the "Object" property below): Having the following data contract: [KnownType(typeof(bool))] [KnownType(typeof(int))] [KnownType(typeof(string))] [KnownType(typeof(Customer))] [KnownType(typeof(Client))] public class Transaction { // properties [DataMember(Name = "UID")] public int UID{} [DataMember(Name = "Type")] public Enums.TransactionType Type{} [DataMember(Name = "Data")] public Object Data{} } and the

问题 faacEncConfigurationPtr FAACAPI faacEncGetCurrentConfiguration( faacEncHandle hEncoder); I'm trying to come up with a simple wrapper for this C++ library; I've never done more than very simple p/invoke interop before - like one function call with primitive arguments. So, given the above C++ function, for example, what should I do to deal with the return type, and parameter? FAACAPI is defined as: #define FAACAPI __stdcall faacEncConfigurationPtr is defined: typedef struct faacEncConfiguration

问题 I'm trying to consume an IBM DataPower 3.7.1.x web service in WCF getting the following error message: Cannot find a token authenticator for the 'System.IdentityModel.Tokens.X509SecurityToken' token type. Tokens of that type cannot be accepted according to current security settings. The HTTP response is coming back as 200 and I can see the correct SOAP response while debugging it in Fiddler. However, the WCF clients doesn't seem to know how to process the BinarySecurityToken element in the

问题 Is there a way using JNI and C# code to create a program that invoke any given Java method? Assume that I have a jar containing classes hierarchy and I'm responsible for loading the JVM and these classes, can I write a C# program that receives the java method signature + arguments values on the fly and call the java code? Please try to restrict your answers to free technologies (JNI solutions prefered). 回答1: IKVM is one option. It implements a JVM in .Net and provides interop tools. 回答2: IMHO

问题 I am building a particle system using OpenGL and OpenCL. I need to share VBOs between OpenGL and OpenCL and therefore create an OpenCL context with the appropriate properties. I am aware that glfw3 exposes some native API functions however I can't figure out how to access the CGL ones. https://github.com/glfw/glfw/blob/master/include/GLFW/glfw3native.h I basically need to find how to run this with glfw3: CGLContextObj kCGLContext = CGLGetCurrentContext(); CGLShareGroupObj kCGLShareGroup =

问题 Using visual basic in say Excel, I am able to declare WinAPI functions using the DECLARE keyword - e.g. Declare Function SetLocaleInfo Lib "kernel32" Alias "SetLocaleInfoA" ( _ ByVal Locale As Long, ByVal LCType As Long, ByVal lpLCData As String ) As Boolean However when using this syntax in a *.VBS file - it fails with a compile error. Can anyone tell me what I need to do to run WinAPI functions from *.VBS files? 回答1: You can't run WinAPI functions from VBScript without some extra third

问题 We have developed a s/w architecture consisting of set of objects developed in C#. They make extensive use of events to notify the client of changes in status, etc. The intention originally was to allow legacy code to use these managed objects through COM interop services. That was easy to write in the design specification but, I'm seeing that actually implementing it is more problematic. I've searched for many hours looking for a good sample of event handling using this method. Before we
