Hello Everyone, Admin. I'm new to this Forum and i want to ask how to search files from a certain directory with progressbar & background worker?Â
Code: (from the Admin-(Brandonio)) :
----------------------------------------------------------------------------------------------------------
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    BackgroundWorker1.RunWorkerAsync()
  End Sub
  Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
    Dim directory = "Path"
    Dim files() As System.IO.FileInfo
    Dim dirinfo As New System.IO.DirectoryInfo(directory)
    files = dirinfo.GetFiles("*", IO.SearchOption.AllDirectories)
    For Each file In files
      ListBox1.Items.Add(file)
    Next
  End Sub
----------------------------------------------------------------------------------------------------------
But whenever i click the button, i get an error saying :Â Cross-thread operation not valid: Control 'ListBox1' accessed from a thread other than the thread it was created on.
----------------------------------------------------------------------------------------------------------
I'm new in VB.NET and i'm making an application that cleans up the Temporary folder.
Thank you. and uh, i like this forum.

I've just finished watching your tenth "Learning Java" part and I want to limit the character number to five digits only.Â
I've tried this:
Code: import java.util.*;
public class digitExtractorTester {
static Scanner userInput = new Scanner(System.in);
public static void main(String[] args){
String rNumber = "12345";
System.out.print("Enter a custom, five digit number: ");
String nSequence = userInput.next();
System.out.println(" ");
if (nSequence.chars() != rNumber.chars()){
System.out.println("Your input contains too many or too less digits.\nOnly five digit numbers are allowed.");
}
else{
digitExtractor byMath = new digitExtractor(Integer.valueOf(nSequence));
byMath.returnNumberSequenceByMath();
System.out.println(" ");
digitExtractor byChar = new digitExtractor(nSequence);
byChar.returnNumberSequenceByChar();
}
}
}
Never mind. I solved my own problem.
If anyone's wondering, I was using chars() when I was supposed to be using length(). (Source of information)
Code: nSequence.length() != rNumber.length()

It has come to my attention that the Krypton Toolkit (ComponentFactory) is no longer available for download. Instead, the page simply contains no download link.
In the past, certain components of the software were free, while others were free for a limited number of days. In order to continue using the software indefinitely, a license key is needed.
Since the files are no longer available from the ComponentFactory webpage, here is the link to 4.4
http://www.megafileupload.com/nb2X/Krypton440.zip
(Apologies for the file provider.. it's a pretty big file)

| Adding backgroundcolor to snake applet |

Hi guys,
first, i'm not the best english speaker and -writer. Therefore i ask you to apologize my language mistakes 
Problably in your eyes, i have a very simply problem, but i cant add the background function to Brandonio's Snake Project. I want to have a black background in the applet. After this, i want to change the color of the grid to white.
I try to add two JPanel's to snakeApplet.java. But is it still not working. Every time i started the Applet, the background is white.
Code: import java.applet.Applet;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import javax.swing.JPanel;
public class snakeApplet extends Applet{
private snakeCanvas c;
JPanel jp1 = new JPanel();
JPanel jp2 = new JPanel();
public void init()
{
jp1.setBackground(Color.BLACK);
add(jp1);
jp2.setBackground(Color.BLACK);
add(jp2, BorderLayout.SOUTH);
c = new snakeCanvas();
c.setSize(new Dimension(640, 480));
c.setPreferredSize(new Dimension(640, 480));
c.setVisible(true);
c.setFocusable(true);
this.add(c);
this.setVisible(true);
this.setSize(new Dimension(640, 480));
}
public void paint(Graphics g)
{
this.setSize(new Dimension(640, 480));
}
}
If the idea of the black background and white grid is not to be a looker, than i would to add a picture in the background of the grid.
But i dont know how i can code it.
I hope someone can help me please
Yours sincerley
Kevin
Edit: Kevin is only a nickname
