1 How do you invoke a COM Class in a specific COM DLL in
.Net?
Imtiaz Alam discusses both early and late binding techniques in his article
entitled Accessing COM+ component using C# on
C# Corner.
2 How do you make .Net components that could be used by
COM?
The tool Regasm.exe can create a COM typelib and creates the necessary
entries in the registry (the CLSID and Typelib ). If only a typelib is
required, you can use tlbexp.exe. A com callable wrapper (CCW) will be
created when a COM client (VB, VBS, JS, C++ etc.) creates an instance of a
(managed) class. Posted on
C# Corner.
3 How can I read and display Excel files from within my
C# application?
.NET's interoperability makes it easy to work with COM Capable Applications
such as Word and Excel.
See Mike Gold's article on
C# Corner
for a detailed discussion.
4 Should I try to use Interoperability or migration to
use COM with .NET?
John Godel tackles this question through a lengthy article on
C# Corner. In it, he discusses the basics (and more) of both .NET
Interoperability and Migration.
5 How can I get events fired by an Office XP chart
control hosted in my Windows Forms app?
To get these events instead of using event delegates, you can create a sink
for the events by using the IConnectionPointContainer and IConnectionPoint
interfaces of the Spreadsheet/Chart component. Here are two articles that
you can check:
