问题 We have been trying to install a COM DLL on a new server. The interface is Classic ASP. The Map Connector DLL seems to be the problem but that is as far as I am able to get. We are unable to get the pages served by IIS to give anything other than a 500 error. When tracing the ASP: 127. -ASP_SCRIPT_TRACE_COM_CALL_END FilePath C:\INETPUB\WWWROOT\MILER\GLOBAL.ASA LineNumber 6 CurrentStatement set g_pcmsrv=Server.CreateObject("PCMServer.PCMServer") SizeOfStatement 55 0 ms 128. -ASP_LOG_ERROR

问题 I need to call methods of the IWeatherStation interface which inherits IUnknown from C#. How do I go about it, if it is possible? Thank you 回答1: Sure. There is an example here: Example COM Class (C# Programming Guide). The first thing you should do is locate the real (idl or c/c++) definition of the interface. For this SDK it's located for example in the < setup path>\Lockheed Martin\Prepar3D v4 SDK 4.3.29.25520\inc\PDK\IWeatherSystem.h header file. This is where you will get the methods and

问题 I have created a COM add-in for Excel 2003 using Visual Studio 2005 Tools for Office. The add-in code looks like this: [Guid("EAC0992E-AC39-4126-B851-A57BA3FA80B8")] [ComVisible(true)] [ProgId("NLog4VBA.Logger")] [ClassInterface(ClassInterfaceType.AutoDual)] public class Logger { public double Debug(string context, string message) { Trace.WriteLine(message); return message.Length; } [ComRegisterFunctionAttribute] public static void RegisterFunction(Type type) { Registry.ClassesRoot

问题 if this possible to write a com control or activex in C# and use it in MFC ? 回答1: Yes. First, you need to create COM object. Below is a very simple example. [Guid("123565C4-C5FA-4512-A560-1D47F9FDFA20")] public interface IDoSomething { [DispId(1)] string Name { get; } [DispId(2)] int DoSomething(); } [ComVisible(true)] [Guid("12AC8095-BD27-4de8-A30B-991940666927")] [ClassInterface(ClassInterfaceType.None)] public sealed class DoSomething: IDoSomething { public DoSomething() { } public string

问题 I have a C# 32-bit COM DLL that talks to a C# 64-bit exe using the 'DllSurrogate' method described in Hosting a .NET DLL as an Out-Of-Process COM Server (EXE). I need this setup because the 32 bit C# talks to a legacy 32-bit C++ dll. I thought everything was working fine, but I have just realised that when you create a second instance of the 64-bit exe you do not get a second "DLL Host" (COM Surrogate) process. This is no good for my application. This is a Windows Desktop application and I

问题 I am trying to follow the steps of a Simple COM Tutorial which looks nice and logical to me. I would normally shy away from using a wizard but consensus seems to be this is the best way to do COM. To summarize Create an ATL project with the wizard Use the Add Class dialog to create an ATL simple object ( SimpleChatServer in the example) Navigate into ClassView, right click the interface for the object, Add Method ( CallMe in the example) The tutorial gives a method body to use Compile My
