ASP .NET (Visual Basic) ICMP Ping Sample Source Code
Network Component provides an easy-to-use development interface to a variety of IP protocols. By using Network Component, you can very easily create or enhance applications with network features.
Network Component features the following: DNS, FTP, HTTP, HTTPs, ICMP Ping, IP-to-Country, MSN, NTP, RSH, SCP, SFTP, SNMP v1/v2c (Get, GetNext, Set), SNMP Traps, SNMP MIB, SSH, TCP, Telnet, TFTP, UDP, Telnet, Wake-On-LAN and more.
Network Component can be well integrated into any development platform that supports ActiveX objects.
This document describes how the Network Component FtpServer object can be integrated into your projects.
The most important functions of the FtpServer object are:
- Connect - connect to the (remote) FTP server on port 21 or any alternate port;
- Disconnect - to diconnect after a connect call;
- GetCurrentDir - retrieve the current directory;
- ChangeDir - change the current directory;
- CreateDir - create a new directory;
- RenameDir - rename a directory;
- DeleteDir - delete a directory;
- FindFile - find a specific file in the current directory;
- FindFirstFile - iterate over all files in the current directory; find the first file;
- FindNextFile - iterate over all files in the current directory; find the next file;
- RenameFile - rename a file in the current directory;
- DeleteFile - delete a file in the current directory;
- 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 Network Component
Download Network Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.
Step 2: Create a new ASP .NET VB Project
Launch Microsoft Visual Studio from the Start menu. Choose 'New' from the 'File' menu and click on 'Web Site'. In the 'Web Site' dialog, select 'ASP .NET Web Application'. Select a name for the application and a name for the solution. Also, select the directory where you want to store the project:
Step 3: Refer to the Network Component Library and create the objects
Now that a new project has been created, you must add a reference to the Network Component library in the project to be able to use the Network Component 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 'Network Component Type Library' as shown in the following picture:
Click 'OK' to close the 'Add Reference' dialog.
Step 4: Create the objects
On top of your code, type the following line to use the Network Component namespace:
In your Main function, declare and create the following object:
Public objFtpServer As FtpServer objFtpServer = New FtpServer()
You can download the complete sample on our FTP site ftp.activexperts-lab.com/samples/network-component/. 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.
