Hi Vasanth,

I'll send it in a view. The playlist part of the code is missing. I've never seen the actual code behind the ListView (I never really used a ListView in programs I wrote).

Due to the missing of part of the code, I have made guesses about parts, but I think you could fit it into your code.

Hi Vasanth,

My mistake. Ater calling DoWaiting, I didn't break the execution of the code (which would result in calling the Thread.Sleep(2000) and thus waiting for 2 more seconds). Change the code to

ResetTime();
if (DoWaiting())
{
e.Cancel = true;
break;
}

Hi Vasanth,

I think I have a solution. I can't test it though and thus I'm not sure if it will solve issue 1.

First of all add the following code:

private int timeInMilliSecondsRemaining = 0; //Initialize the time at 0.

private bool DoWaiting()
{
while (timeInMilliSecondsRemaining > 0)
{
Thread.Sleep(200); // 200 milliseconds
timeInMilliSecondsRemaining -= 200; // substract waited time from timeremaining
if (backgroundWorker1.CancellationPending)
{
return true;
}
}

timeInMilliSecondsRemaining = 0;
return false;
}

private void ResetTime()
{
// Only reset time if the current time has been finished, otherwise resume
if (timeInMilliSecondsRemaining <= 0)
timeInMilliSecondsRemaining = Convert.ToInt32(listview_playlist.SelectedItems[0].Tag.ToString());
//timeInMilliSecondsRemaining = Convert.ToInt32(txtboxSleep.Text);
}

Secondly change part of the loop into:

backgroundWorker1.ReportProgress(i * 100 / count, j);
//Thread.Sleep(2000);
//if (backgroundWorker1.CancellationPending)
//{
// e.Cancel = true;
// break;
//}
ResetTime();
e.Cancel = DoWaiting();

The code does the following. To pause you need something to pause. In the former code the backgroundworker did wait the required seconds and then checked to see if a cancellation was pending. So it was inpossible to stop halfway. The DoWaiting method checks every 0.2 seconds if a cancellation is pending.

To check the time remaining I added a int with the time remaining in milliseconds. When the time remaining reaches 0, the waiting will be finish. DoWaiting returns true if the pause button has been hit (assuming that your pausebutton will cancel the background worker).

To set the time remaining I added the ResetTime method. It will take the time form the playlist (you might need to mulitply the seconds with 1000, i forget that).

Concerning Issue 1 this also might be solved. When you push the start button the reset time function will check if there was a time remaining and the code will continue where it left. If you don't want this funcionality, then remove the 'if (timeInMilliSeccondsRemaing <= 0)'

I hope it will work
