File Copy With JProgressBar

Question

Hi i'm using the below code to copy a file and display the progress on screen. However the file copies ok by the progressbar is never shown. Can somebody please show me how to use the JProgressBar Component to copy a file and show the progress?
Thanks
Arlef
public void copyFileToMediaFolder(File f){
String newFileName = f.getName();
try{
File inputFile = f.getAbsoluteFile();
int fSize = (int)f.length();
FileCopyProgress fcp = new FileCopyProgress(this,true);
File outputFile = new File(mediaFolder + File.separatorChar + newFileName);
FileInputStream in = new FileInputStream(inputFile);
FileOutputStream out = new FileOutputStream(outputFile);
int c;
int bytesRead = 0;
int counter = 0;
while ((c = in.read()) != -1){
out.write(c);
counter = counter + 1;
bytesRead = fSize / 100 * counter;
in.close();
out.close();
fcp.dispose();
}catch(Exception ex){
//System.out.println("nEW FILE NAME = "+newFileName);
}

Answer 1

The progressbar is in a JDialog and is represented in
the following line in the code i sent earlier
FileCopyProgress fcp = new FileCopyProgress(this,true);Yes, i'm aware of that, but what I'm saying is that you don't seem to be updating the status of the progressbar while copying the file...I suppose the progressbar would start with 0 or 0% and then there should be some functions to be called to make it "progress" to 10..20...50..60% etc... So I believe you should call such a function from inside the loop where the file is being copied...I remember it used to be like that in Visual C++, so i'm supposing the behavior is similar in Java.
Good luck :)
