Part I: Using COM components in .NET framework In this article we review the concepts & walk-through an example that demonstrates COM interoperability in .NET framework. What is the need for Interoperability?COM components have different internal architecture from .NETcomponents hence they are not innately compatible. Most organizations,which have built their enterprise applications on COM objects [...]

Prologue This document arose when I began to seriously think about connecting to Sybase databases from C# applications. My first attempt was to use the ODBC layer. It was immediately clear that this approach was not going to work. It was about 100 times slower than the usual CT-Library/C++ solution. The framework comes equipped with [...]

Part I – Using COM in .NET COM is very deeply rooted in Microsoftproducts and it is not easy to neglect COM completely. There may besituations arise where you required to build COM in VC++ and you wantto use it in C# or even you want to use your old components. But don'tbe panic because [...]

Download : Source Code The topics covered in this article are Creating a simple COM Object in C# ( use the COM Interop property ) Accessing the COM from a VC++ Client . ( I have tested it with VC++6.0 & VC++ .NET ). Client uses the TypeLibrary ( .TLB file ) For the sake [...]

This article provides examples of using a COMcomponent in Microsoft.NET application and also using a Microsoft.NETcomponent in a normal Visual Basic 6.0 application. Many authors hadwritten about this. However, we would like to be very brief andstraight to the point in more practical way. Exposing COM components to Microsoft .NET framework First we will look [...]

Introduction: In this article I cover the areaInteroperability issues. There is no doubt that with the help of .Netone can create powerful components and Distributed applications thanany other language. But we have to think over about the past reusablecomponents, which were created by many languages such as VB etc. Is it the Usage of those [...]

COM Interoperability is the feature of Microsoft .Net that allows managed .Net code to interact with unmanaged code using Microsoft’s Component Object Model semantics. Most of the hoopla about COM Interoperability in .NET centers on the ability of .Net code to invoke legacy COM objects (such as ActiveX controls and COM objects encapsulated in DLLs). [...]
