For my memo  only

at D:......PortTEstsrc>java porttest.PorTest, app window will comes out

:)

Thanks for your reply and it is good practise for java tuturial before using
too friendly Java tool

I think the tools is for direct access I/O serial port, RIght not for Internat Network card
port access ?

Duncan

Did you run the PortTest window,

it need us to specifiy Address(hex) value,

If I want to read port 10000 and just type
2710 (Decimall 10000) and let Value is empty to read

Right ?

it run suddenly but the window of NTport need to register copy?

Could you use it for I/O port read and wirte?

There is a lot of java ibrary path. Which one is correct ? How about include the NTPortjava.dll at command line, javac, with -classpath, Is it okay?

copy NTPortJava.dll %WINDIR%

No right to access

And run your Props ,give me the result as follows

Where I should put the NTPortJava.dll in my directory ?

So when You use Elicipse, it create other syntax to be remember.I don't know why they will create such more package or directory for so called  such as nonesense system manner or directory handling .Lanauge is similar to the C but the operation is more complicate to C . it intends wants users not to use java like Ie browser or windows.

java java porttest.PortTest

Your command is wrong, What is java java ?please advise, just three files spend
a lot time.

I found the NTPortJava.Dll ?

But how to include it on java
is it ?

javac -d . -classpath NTPortJava.dll Frame1.java

But it is still not working, and report the same could find the symbol

Duncan

Neither, but you certainly need the dll loaded by the app. Get it wherever you got the code from if you can

http://technojeeves.com/joomla/index.php/free/118-errors

Works fine for me (compilation)

Dear CEJI,

import NTPortJava.*;
That means I need jar file or .dll file, please advise ?
How to make dll if so

Duncan

Dear CEJi,

it is not working, the NTPortJava could not be found
package porttest;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.*;
import NTPortJava.*;
