  • .NET remoting: System references wrong .NET dll, but how to cure ?

    - by Quandary
    Question: I defined an interface like below. The problem now is, that when I add the dll (API.dll) as reference in an asp.net project, it references a wrong API.dll, though I referenced the correct dll. In turn, it doesn't find GetLDAPlookup, but there is another method that is not in defined here, but in an older version of API.dll... I rebuilt the dll I referenced, so it is definitely the latest version that I added as reference. Do I have to add another GUID, or something ? Imports System.Runtime.InteropServices Namespace RemoteObject ''' <summary> ''' Defines server interface which will be deployed on every client ''' </summary> ''' <GuidAttribute("921DE547-32FA-40BB-961A-EA390B7AE27D")> _ Public Interface IServerMethods ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="strMessage">Some text</param> ''' Sub ServerPrint(ByVal strMessage As String) ''' <summary> ''' Function to call the server from the client ''' </summary> ''' <param name="strMessage">Some text</param> ''' <returns>Some interesting text</returns> ''' Function GetLDAPlookup(ByVal strMessage As String) As System.Data.DataSet End Interface End Namespace

  • Language neutral plugin architectures

    - by Mmarquee
    I am looking at extending an existing application through the use of a plugin architecture. The application id written in Delphi, but I want to be able to implement various plugins in whatever language is best of the job. Currently we have skills in Delphi, C# and Java, and would like to be able to implement a plugin in whatever language is required. Does anyone know of an example system that can be used to implement this ? I am assuming that I could standardise on a particular COM interface and anything that implements that interface could be a plugin. Does anyone have any pointers ? Thanks

  • Millisecond-Accurate Scheduling of Future Events in C++/CLI

    - by A Grad Student at a University
    I need to create a C++/CLI mixed assembly that can schedule future calls into a native DLL with millisecond accuracy. This will, of course, mean setting a timer (what kind?) for a millisecond or three beforehand, then spinning until the moment and calling the native DLL function. Based on what I've read, I would guess that the callback that the timer calls will need to be native to make sure there are no thunks or GC to delay handling the timer callback. Will the entire thread or process need to be native and CLR-free, though, or can this be done just as accurately with #pragma unmanaged or setting one file of the assembly to compile as native? If so, how? If there is indeed no way to do this in mixed-mode C++/CLI, what would be the easiest way to set up an app/thread (ie, DLL or exe?) to handle it and to get the data back and forth between the native and managed threads/apps?

  • Why does Ordered[A] use a compare method instead of reusing compareTo?

    - by soc
    trait Ordered[A] extends java.lang.Comparable[A] { def compare(that: A): Int def < (that: A): Boolean = (this compare that) < 0 def > (that: A): Boolean = (this compare that) > 0 def <= (that: A): Boolean = (this compare that) <= 0 def >= (that: A): Boolean = (this compare that) >= 0 def compareTo(that: A): Int = compare(that) } Isn't it a bit useless to have both compare and compareTo? What is the huge benefit I'm missing here? If they had just used compareTo I could just had replaced Comparable with Ordered in my code and be done.

  • How to pass a const unsigned char * from c++ to c#

    - by tzup
    So I have a function in unmanaged c++ that gets called when some text happens to have "arrived": #using <MyParser.dll> ... void dump_body(const unsigned char *Body, int BodyLen) { // Need to pass the body to DumpBody, but as what type? ... lMyParser::Parser::DumpBody(???); } DumpBody is a function defined in a C# DLL that should take one parameter of type? Body holds an array of characters (text) of length BodyLen. There's obviously some marshalling to be done here but I have no idea how. Please help.

  • Exposing a C++ API to C#

    - by Siyfion
    So what I have is a C++ API contained within a *.dll and I want to use a C# application to call methods within the API. So far I have created a C++ / CLR project that includes the native C++ API and managed to create a "bridge" class that looks a bit like the following: ManagedBridge.h namespace ManagedAPIWrapper { public ref class Bridge { public: int bridge_test(void); int bridge_test2(api_struct* temp); } } ManagedBridge.cpp int Bridge::bridge_test(void) { return test(); } int Bridge::bridge_test2(api_struct* temp) { return test2(temp); } I also have a C# application that has a reference to the C++/CLR "Bridge.dll" and then uses the methods contained within. I have a number of problems with this: I can't figure out how to call bridge_test2 within the C# program, as it has no knowledge of what a api_struct actually is. I know that I need to marshal the object somewhere, but do I do it in the C# program or the C++/CLR bridge? This seems like a very long-winded way of exposing all of the methods in the API, is there not an easier way that I'm missing out? (That doesn't use P/Invoke!)

  • Binding Data to Word 2007 Content Controls Using Visual Studio Tools for the Office System (3.0)

    - by Simon Lomax
    Hi, I found this article (http://msdn.microsoft.com/en-us/library/bb967663.aspx) and thought great thats exactly what I'm trying to do. I want to programatically build a product brochure using content controls and openXML. The article in question refers to an accompanying video which unfortunately does not appear to be available, nor does the code. I posted a comment to ask where they are but in the meantime does anybody know of a good example. There are plenty of examples of binding/merging one record into a openXML Word document. But I want to bind a whole list of records to create a product brochure. Can anyone point me to good tutorial? Thanks

  • Creating a C# DLL and using it from unmanaged C++

    - by John
    I have a native (unmanaged) C++ application (using wxWidgets for what it's worth). I'm considering a separate tool application to be written in C# which would contain winform-based dialogs. putting some of those dialogs in a separate DLL would be useful as I'd hope to be able to use them from my C++ app. But I have no idea how much messing about is needed to accomplish this, is it particularly easy?

  • structure in .NET

    - by redpaladin
    My problem is very simple.. My problem is to send a structure beetween a program in C to a C# program.. I made a struct in C#: public struct NetPoint { public float lat; // 4 bytes public float lon; // 4 bytes public int alt; // 4 bytes public long time; // 8 bytes } Total size of the struct must be 20 bytes When i do a sizeof() of this struct System.Diagnostics.Debug.WriteLine("SizeOf(NetPoint)=" + System.Runtime.InteropServices.Marshal.SizeOf(new NetPoint())); The debug console show : SizeOf(NetPoint)=24 But i expected to have 20 bytes ? Why do I have a difference ? Thank you in advance

  • Blittable Vs. Non-Blittable in IL

    - by Michael Covelli
    I'm trying to make sure that my Managed to Unmanaged calls are optimized. Is there a quick way to see by looking at the IL if any non-blittable types have accidentally gotten into my pinvoke calls? I tried just writing two unmanaged functions in a .dll, one that uses bool (which is non-blittable) and one that uses ints. But I didn't see anything different when looking at the IL to let me know that it was doing something extra to marshal the bool.

  • Add 64 bit offset to a pointer

    - by Novox
    In F#, there's the NativePtr module, but it seems to only support 32 bit offsets for its’ add/get/set functions, just like System.IntPtr does. Is there a way to add a 64 bit offset to a native pointer (nativeptr<'a) in F#? Of course I could convert all addresses to 64 bit integers, do normal integer operations and then convert the result again to nativeptr<'a, but this would cost additional add and imul instructions. I really want the AGUs to perform the address calculations. For instance, using unsafe in C# you could do something like void* ptr = Marshal.AllocHGlobal(...).ToPointer(); int64 offset = ...; T* newAddr = (T*)ptr + offset; // T has to be an unmanaged type Well actually you can't, because there is no "unmanaged" constraint for type parameters, but at least you can do general pointer arithmetic in a non-generic way. In F# we finally got the unmanaged constraint; but how do I do the pointer arithmetic?
