Step 1: Create a new Visual C++ project

Launch 'Microsoft Visual C++' from the Start menu, and choose 'New' from the 'File Menu'. The 'New' dialog appears.

Select the type of project (for instance: 'Win32 Console Application'), enter a 'Project name' and select the 'Location':

Select the kind of project, for instance a 'Hello, world!' application and click 'Finish':

Step 2: Refer to the Network Component Library and declare the objects

A new Project is created now.

Before you can use Network Component, you need to refer to the Network Component library. The actually reference files are shipped with the product and are located in the following directory:

C:\Program Files\ActiveXperts\Network Component\Examples\Visual C++\Include

Copy all files in the above directory ('AxNetwork.c', 'AxNetwork_i.c' and 'AxNetworkConstants.h') to your project directory.

On top of your code, declare the following object:

Step 3: Create the objects

Since the Network Component is a COM object, you must initialize the COM library before they can call COM library functions (e.g. Network Component functions):

CoInitialize(NULL);

Create the object in the following way:

CoCreateInstance(CLSID_TftpServer,NULL,CLSCTX_INPROC_SERVER,IID_ITftpServer,(void**) &pTftpServer);

You can download the complete samples here. There are many other working Network Component scripts on our site and shipped with the product.

NOTE: Demo Projects are created with Microsoft Visual Studio 2008

The Network Component project ships with a set of Microsoft Visual Studio .NET samples, including samples for Microsoft Visual C# .NET. The projects are created with Microsoft Visual Studio 2008.

Users with a later version of Microsoft Visual Studio can open such a project. The Visual Studio Conversion Wizard will guide you through the process of converting the project to the version used.
