Migrating COM/DCOM Applications in Microsoft .NET Framework
In the current Internet scenario, various classic applications run on multiple networks. These applications could have been written using different languages like Visual Basic, Visual C++. For example, a retail organization would have different systems, such as an inventory management system, a bill of material systems, and a general ledger system, all implemented using various technologies available for application development. These systems need to be integrated to form a higher-level enterprise information system for an organization.

Mapping Microsoft Excel columns with XML data (XML data integration) programmatically using a .Net Application.
Using this program you can map Excel columns programmatically and generate an XML file containing the cell values that you had in your Excel document. After generating the XML file we can read it into a dataset.
DTS Custom Task in C#
During last year I wrote an article about DTS and how to use it in C#. In that article I stated that I didn’t manage to solve the problem related to CustomTask. Today I finally forced myself to tackle that problem again and here is the result. Writing simple CustomTask in C# is the easiest part.
Platform Invocation Services in .NET Framework
This article will cover the details of Platform Invocation Services provided in .Net Framework. Platform Invoke Services acts as a bridge between the managed and unmanaged code. This service enables managed code to call unmanaged functions which are being exposed by any dynamic link libraries (DLL’s) such as Win32 API’s or any custom DLLs.

The Interoperability services make it very easy to work with COM Capable Applications such as Word and Excel. This article reveals using Excel from a managed application. Excel is the spreadsheet component of Microsoft Office 2000.
C# and ActiveX DLL
As you know with Visual Basic 6.0, it is possible develop a COM server and implement them in a Visual Basic client program. But this is being done by using Visual Basic. You may wonder about the idea of calling this DLL in a C# Application. Well, C# language provides us a way to call this COM server in a program. When we compile a C# program an Intermediate Language is generated and it is called as Managed Code.
XP, Component Services and .NET
First of all, COM+ does revolutionize COM; it is not only a superior new version of the COM programming model it is also a new platform to design and develop components. In addition, COM+ Services in XP does have some differences from Windows 2000; also XP and COM+ 1.5 offer a richer set of services than was available in COM+ 1.0. This article will describe the basic component services on the XP.
