To use a Distinct ActiveX control in a Visual J++ applet, the applet
must include definitions of the actions and errors for the control. These definitions are
listed in the D_*.java file (where * represents the control name) shipped with the ActiveX
control. For example, the D_FTP.java file contains the definitions for the FTP control.
The contents of this file must be included in the class that uses the control. Next, a
wrapper class must be made for the control. Select Java Type Library Wizard from the Tools
menu, and check the Distinct ActiveX control of interest. Click on the OK button. This
wrapper class must then be imported.
As Java is unable to catch events, the java applet and ActiveX control need to be
placed on a html page and VBScripting needs to be used to catch the ActiveX control events
and pass them to the java applet. The VBScript must also initially pass the ActiveX
control to the java applet. See the readmeVJ.doc in the ..\samples\VJ directory for
detailed instructions and example code on how to implement this.
You must have Microsoft SDK-JAVA 2.0 or later and the Microsoft Virtual machine for
Java installed to run these samples.
Samples are stored in the VJ folder. Below we describe what each sample
does. The folder column shows the subfolder name that contains one or more samples and the
ActiveX control whose use is illustrated by the sample.
| Folder |
Included Samples |
| Daytime (Windows Sockets ActiveX) |
The daytime sample program illustrates how make a UDP
or TCP connection to the remote host and retrieve the reply from the host. |
| Finger (Finger ActiveX) |
This program illustrates how to include Finger functionality
into an application using the Finger ActiveX control. |
| Firewall (Firewall ActiveX) |
There are two samples in this folder each of which illustrate
how to program your application to handle connections through SOCKS firewalls: Daytime:
This shows you how to make a connection to a remote host through a firewall and how to
retrieve the hosts reply.
Send: This sample shows how to connect to a host through a firewall server to
send a message. |
| FTP(FTP Client ActiveX) |
The ftpclnt sample program shows you how to make a
connection to the FTP server, send FTP commands and close your FTP connection. It
demonstrates much of the functionality of the FTP client ActiveX control, illustrating the
functions as menu items to simplify the code breakdown and allow the programmer to quickly
find some sample code for a particular method or property. This sample also illustrates
how to connect to an FTP server through a SOCKS firewall proxy. |
| FTPSRV (FTP Server ActiveX) |
This ftpsrv sample program shows you how to integrate
an FTP server that is capable of creating and modifying a client database, servicing
several clients (up to 64) simultaneously and providing statistics on client activity. It
demonstrates much of the functionality of the FTP server ActiveX control, illustrating the
functions through a simple interface, user database structure and menu items to simplify
the code breakdown and allow the programmer to quickly find some sample code for a
particular method or property. This program illustrates how to write a custom FTP server
application using the FTP Server ActiveX control. |
| Message (Windows Sockets ActiveX) |
This folder contains two programs recv and send that are
intended to work together to illustrate how to write the client and server side of a TCP
connection using the Windows Sockets control. |
| MIME (Mime, SMTP and POP ActiveXs) |
This folder contains three subfolders each with a sample
application: Mime: The Mime program shows how to encode and decode files, and how
to create and extract messages with attachments
SmtpMime: The SmtpMime sample illustrates the combined use of the SMTP and MIME
ActiveX controls. It illustrates how to create an SMTP plain text message and attach MIME
or UUencoded files. It then emails the messages using SMTP. You need to have a valid SMTP
server to run this sample.
PopMime: The SmtpMime sample illustrates the use of the Mime ActiveX in
conjunction with the POP ActiveX. It shows you how to connect to a POP3 server, download
and extract MIME encoded or UUencoded mail messages. |
| NNTP (NNTP ActiveX) |
The nntpclnt sample program illustrates how to access
a News server using the NNTP ActiveX control. The NNTP sample shows how to read, post,
position and list news articles and how to navigate news groups. It also illustrates how
to connect to the remote server through a firewall proxy. |
| POP (POP ActiveX) |
The popclnt sample program shows you how to make a
connection to the POP 2 or POP 3 server, send POP commands, download messages, and close
your POP connection. It demonstrates much of the functionality of the POP client ActiveX
control, illustrating the functions as menu items to simplify the code breakdown and allow
the programmer to quickly find some sample code for a particular method or property. |
| RCP (RCP ActiveX) |
The rcpclnt program illustrates how to include remote
copy operations into an application using the RCP ActiveX control. This sample shows how
to copy files between the local and remote machine, or from one remote machine to another.
It also illustrates how to do recursive file copying. The sample also allows you to create
a new file and save it to a remote file as well as view the contents of a remote file. |
| Resolve (Windows Sockets ActiveX) |
The resolve program illustrates how to resolve a host
name to an internet address, or an internet address to a host name using the Windows
Sockets ActiveX control. |
| RLIB (RLIB ActiveX) |
The rlibclnt program illustrates how to include remote
command execution into an application using the RLIB ActiveX control. The sample
demonstrates the use of remote execution (Rexec), remote shell(rsh) and remote
login(rlogin). Note: In order to be able to connect using RLIB (RSHELL &
REXEC) you must make the PC running RLIB client, a trusted host on the Unix machine that
you are trying to connect. |
| Server (TCP Server ActiveX) |
This folder contains two sub folders one with a client
application and one with a server application. They are intended to be run together to
illustrate how a server application handles a client call: Tcpclnt: This is a
simple windows sockets application that makes a connection to a TCP server and sends data
to the server
Tcpsrv: This is a very simple server application that can be put in listen mode
to accept TCP connections and data sent from the tcpclnt application. For simplicity this
sample has only two display windows and accepts two concurrent connections. You can modify
the sample to accept more connections. |
| SMTP (SMTP ActiveX) |
The smtpclnt sample program shows you how to make a
connection (including connecting through a SOCKS firewall server) to the SMTP server, send
SMTP commands and mail, and close your SMTP connection. It demonstrates much of the
functionality of the SMTP client ActiveX control, illustrating the functions as menu items
to simplify the code breakdown and allow the programmer to quickly find some sample code
for a particular method or property. |
| Telnet (Telnet ActiveX) |
The telnet sample program illustrates how to include
Telnet type login capabilities into an application. It establishes a telnet connection
(with the option of establishing this through a SOCKS firewall), allows you to send telnet
commands and disconnects from the server. |
| TFTP (TFTP ActiveX) |
The tftpclnt sample program illustrates how to include
TFTP file transfer functionality into an application using the TFTP ActiveX control. It
demonstrates how to copy files between the local and remote machine, or from one remote
machine to another. |
| VT220 (VT220 ActiveX) |
The VT220 sample program illustrates how to include
complete VT220 terminal emulation into an application using the VT220 ActiveX control.
This sample shows how to manage and customize configurations, how to capture data from the
remote terminal, and how to map the keyboard. |
| WhoIs (WhoIs ActiveX) |
This program illustrates how to include WhoIs functionality
into an application. |
