Microsoft Visual C++ Users

VC++ users need to setup the builder environment prior to start to 
build your program. There are few steps you need to follow as 
below:

1. Open the solution file (baseclasses.sln) or the project file 

(baseclasses.dsw) under %DXSDK%\Sam-
ples\C++\DirectShow\BaseClasses and build it.

In above, %DXSDK% is the path of DirectX SDK.

2. Add the paths to the include directory in the settings of 

your project:

%DXSDK%\include

%DXSDK%\Samples\C++\DirectShow\BaseClasses

3. Add the paths to the additional library directory in the 

settings of your project:

%DXSDK%\Lib

%DXSDK%\Samples\C++\DirectShow\BaseClasses\Release

.Net Programming Users

Microsoft DirectShow only provides C++ programming. As for .net 
users, they need convert DirectShow COM objects to .net class. 
Fortunately, the work had been done as a sourceforge project. 
Download the source codes and samples from 

http://sourceforge.net/projects/directshownet/. It is a good start to 
program your DirectShow codes by .net languages. We also pro-
vided samples dedicated to RTV cards in the installation directory.
