MP3 Player
Create your own mp3 player. Provides basic functionality, plus dynamic playlist management. The code uses custom toolbars as player buttons (including tooltips), and MCI library strings to operate the player. A second window with a child listbox is designed to add to and delete from a playlist. The playlist is managed as a linked list during the session, and stored in a file upon exit, so it can be loaded at next start-up.

Do you know that you can call Java classes from Visual Basic ??
well, that's not a fair tale anymore, it's possible.
let me guide you through this adventure.
Firts at all, we need a Java class,
Here you will find an example:
Java Code
//**************************************************
public class MyTest {
public int myfunction(int value1, int value2) {
return value1+value2;
}
}
//***************************************************
Compile it
i.e. javac MyTest.java
and when you get MyTest.class file, you must register it
for this you will need Microsfot SDK for Java
you can download from this link
http://www.microsoft.com/java/download/dl_sdk40.htm
when you have downloaded and installed.
include it on Path variable enviroment
just do it using Command Ms-DOS
set path=%path%;C:\Program Files\Microsoft SDK for Java 4.0\bin\
(this path could change)
then you must register our MyTest.class file.
you should do it using javareg.exe file from Microsoft SDK for Java
i.e. javareg /register /class:MyTest /progid:MyTest
if everything is well-done then you should see a MessageBox displayed with
Succesfull register Class message.
Otherwise, you must check the correct spelling on the command line.
Now, the next step, copy the new Java class file that was generated.
MyTest.class
and paste in C:\Winnt\Java\Trustlib\ folder
if you have windows 98, this folder may change.
And the last step, open a New Project on Visual Basic.
And paste this brief code on the Form Load event for example and run it.
Set x = CreateObject("MyTest")
MsgBox x.myfunction(1, 1)
Congratulations !!!
you can use Java Class from Visual Basic.
