ActiveSocket can be well integrated into ASP environments. This document describes how the ActiveSocket TftpServer object can be integrated into ASP .NET (C#) projects.

The most important functions of the TftpServer object are:

  • GetFile - get (download) a file, either using binary transfer or ASCII transfer;
  • PutFile - put (upload) a file, either using binary transfer or ASCII transfer.

Step 1: Download and install ActiveSocket

Download the ActiveSocket Toolkit from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create a new ASP .NET C# Project

Launch Microsoft Visual Studio (for instance 'Microsoft Visual Studio 2005') from the Start menu. Choose 'New' from the 'File' menu and click on 'Web Site'. In the 'Web Site' dialog, select ASP .NET Web Site. Select a name for the application (for instance: 'DemoApp') and a name for the solution (for instance: 'DemoSolution'). Also, select the directory where you want to store the project (for instance: 'C:\MyProjects):

Step 3: Refer to the ActiveSocket Library and create the objects

Now that a new project has been created, you must add a reference to the ActiveSocket toolkit in the project to be able to use the ActiveSocket object. To do so, choose 'Add Reference...' from the 'Project' menu. In the 'Add Reference' dialog that pops up, select the 'COM' tab and select the 'ActiveSocket 2.4 Type Library' as shown in the following picture:

Click 'OK' to close the 'Add Reference' dialog.

On top of your code, type the following line to use the ActiveSocket namespace:

   using ASOCKETLib;

In your Main function, declare and create the following object:

   public TftpServer m_objTftpServer;

   m_objTftpServer = new TftpServer();
