So
far about 60 people have downloaded my little TiVo Decoder GUI
program and I have received some suggestions for improvements from
some fine folks at the TiVo forums. I'm currently working on the
next version that will hopefully incorporate most of these
improvements.
For
the first time, I have decided to use a software configuration
management tool to help me with this process. I decided to use
Visual Source Safe 6.0d because I had purchased a copy at a computer
show awhile ago and it integrates nicely with Visual Studio 2005.

Managed Wrappers |

.NET World

Let’s recap what we know about interoperating with legacy code from .NET. We basically have two methods.
If the legacy code is in the form of a DLL, we can use P/Invoke from any .NET language. We can also use C++ Interop if we are using C++/CLI to access this DLL.
If the legacy code is in the form of a C/C++ source file, then we can use C++ Interop to access it.
No matter which method we choose to interoperate with legacy code, we should consider wrapping up our work into a package that will be useable from any of the .NET languages. This technique involves creating a managed wrapper that acts as a proxy for the legacy native code.
Once this is done, the legacy code will then be available to any other .NET language as a .NET class. So, we tradeoff some more work in the beginning for less work further down the line.
For example, suppose our legacy code is already in the form o ...

Value Types, Reference Types, Boxing and Unboxing |

Most
of the .NET literature I've come across reads somewhat easily because
it is so similar to Java and I had already taken several Java
classes.
But
one of the things that I find confusing in the .NET literature is
their talk of boxing and unboxing and their emphasis on Value Types
and Reference Types. I couldn't remember
a similar topic in Java. What I do remember from Java was that ...

Using C++ Interop to access Legacy code |

C++
Interop, also known as “It Just Works”, is only available if you
are using C++/CLI. It is my preferred way of accessing legacy C/C++
code. The basic idea is that things should work as they have always
worked before .NET came along. In other words, if you want to access
functions within a DLL from C++/CLI, you perform the same steps as if
you were using Visual C++ 6.0.
To
illustrate how this is done, suppose you have access to a legacy
library packaged in a DLL called MathDLL.dll. This is the same
library that I used earlier to illustrate how to use P/Invoke to
access functions in a DLL.
Now
suppose you use Visual Studio 2005 to create a ne ...

In 2002, Microsoft introduced a new programming framework called the .NET Framework. Programs written in any .NET language are compiled to an intermediate code called the Microsoft Intermediate Language (MSIL) and this intermediate code is run on top of something called the Common Language Runtime (CLR). The .NET Framework also includes a large set of prewritten classes called the Framework Class Library.
The Microsoft Intermediate Language, C ...

A GUI front end for TiVo Decoder |

TiVo Decoder GUI is a GUI front end to the TiVo Decoder utility written by Jeremy Drake.
TiVo Decoder converts TiVo files (obtained from using TiVo Desktop) into standard MPEG2 files which can then be used to produce a DVD that is playable on any DVD player. Prior to TiVo Decoder, the only official way to produce a DVD from your TiVo files was to use Roxio's MyDVD or Easy Media Creator.
