PowerTCP Server for ActiveX

PowerTCP Server for ActiveX Features

FtpServer ActiveX Control

The FtpServer control is used to build custom FTP server applications. Features include:

 

• The FtpServer control uses an internal Daemon object and dynamically creates internal TCP objects as each passive connection is automatically accepted. Use this TCP object to send and receive data to that individual connection.
• When a request is received, a corresponding event is raised. Write your own custom handling code in the event handler.
• Add authentication and customized user directories within the Login event.
• Disallow changing directories within the ChangeDirectoryUp and ChangeWorkingDirectory events to those who do not have proper permissions.
• Disallow directory creation/deletion within the MakeDirectory and RemoveDirectory methods to those who do not have proper permissions
• Disallow file upload/download within the Retrieve and Store event to those who do not have proper permissions.

 

Development Environments

• Visual Studio .NET (.NET Framework)
• Visual Basic (VB)
• Visual C++ (VC++)
• FoxPro
• ASP
• Office 97/2000
