ActiveSocket can be well integrated into ASP environments.
This document describes how the ActiveSocket FtpServer object can be integrated into HTML 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: Installation of ActiveSocket

When using HTML, there are two ways to install the ActiveSocket Toolkit on a client PC:

Automatically using HTML code;
Using the ActiveSocket Toolkit InstallShield installation.

Automatic installation using HTML code

You can install the ActiveSocket Toolkit automatically using the following HTML code on top of the HTML page:

   <head>
      <object id="objSnmpManager" codeBase="http://www.activexperts.com/files/activsocket/asocket.dll" height="30" width="200" 
              classid="CLSID:4F986D6D-E04F-4BEE-B8C7-8252577CB282" viewastext></object>
   </head>

The ActiveSocket Toolkit will be installated automatically. The user will be asked to confirm the installation, because the DLL is coming from an untrusted site (www.activexperts.com).
There are two ways to avoid prompting:

Add the ActiveX/COM location to the user's trusted sites. You can manage trusted manually (by using the Internet Explorer), through a logon script (by appyling the registry change from the logon script) or by using Active Directory Group Policies;
OR use a trusted location for the DLL. For instance your Intranet site, because most probably this site has already been added to the list of trusted sites for all users.

Manual installation using the ActiveSocket Toolkit installation procedure

On each client PC, download the ActiveSocket Toolkit from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.
