Question

I am trying to make a progress bar form load and while loading, if I press the cancel button the whole application will stop whatever it is doing.

Below is my code calling the progress bar form. I was wondering anyone could help out with this?

Loading loader = new Loading();


    private void lockButton_Click(object sender, EventArgs e)
    {
        if (this.ddCheckBox.Checked == false)
        {
            if (this.passwordtextBox.Text == "")
            {
                MessageBox.Show("Please enter a password!");
            }
            else if (this.retypeTextBox.Text == "")
            {
                MessageBox.Show("Please retype password!");
            }
            else if (this.passwordtextBox.Text == this.retypeTextBox.Text)
            {
                //details = new Details();
                details.SetPassword(this.passwordtextBox.Text);

                if (this.EncryptionComboBox.Text == "AES - 128 bit" | this.EncryptionComboBox.Text == "AES - 192 bit" | this.EncryptionComboBox.Text == "AES - 256 bit")
                {
                    this.Hide();

                    Thread thread = null;
                    thread = new Thread(new ThreadStart(delegate() { loader.dLabel.Text = "Locking Files..."; loader.ShowDialog(); }));
                    thread.Start();

                    details.SetEncryption(this.EncryptionComboBox.Text);

You should use a BackgroundWorker for this, instead of System.Threading.Thread.
