    <p>How can I create a progress bar and a playlist for a media player? I'm making my own media player in C#.</p> <p>Here is the code to play a file</p> <pre><code>using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using QuartzTypeLib; using System.Runtime.InteropServices; namespace trying { public partial class Form1 : Form { [DllImport("winmm.dll")] public static extern int waveOutGetVolume(IntPtr hwo, out uint dwVolume); [DllImport("winmm.dll")] public static extern int waveOutSetVolume(IntPtr hwo, uint dwVolume); public Form1() { InitializeComponent(); } // Define constants used for specifying the window style. private const int WS_CHILD = 0x40000000; private const int WS_CLIPCHILDREN = 0x2000000; // Hold a form-level reference to the media control interface, // so the code can control playback of the currently loaded // movie. public IMediaControl mc =null; public IMediaPosition m=null; // Hold a form-level reference to the video window in case it // needs to be resized. public IVideoWindow videoWindow = null; public int a; private void button1_Click(object sender, EventArgs e) { if (mc != null) { mc.Run(); } } private void button2_Click(object sender, EventArgs e) { mc.Stop(); } private void button3_Click(object sender, EventArgs e) { mc.Pause(); } private void trackBar1_Scroll(object sender, EventArgs e) { //Calculate the volume that's being set int NewVolume = ((ushort.MaxValue / 10) * trackBar1.Value); // Set the same volume for both the left and the right channels uint NewVolumeAllChannels = (((uint)NewVolume &amp; 0x0000ffff) | ((uint)NewVolume &lt;&lt; 16)); // Set the volume waveOutSetVolume(IntPtr.Zero, NewVolumeAllChannels); } private void newFileToolStripMenuItem_Click(object sender, EventArgs e) { // Allow the user to choose a file. OpenFileDialog openFileDialog = new OpenFileDialog(); openFileDialog.Filter = "Media Files|*.mpg;*.avi;*.wma;*.mov;*.wav;*.mp2;*.mp3|" + "All Files|*.*"; if (DialogResult.OK == openFileDialog.ShowDialog()) { // Stop the playback for the current movie, if it exists. if (mc != null) mc.Stop(); // Load the movie file. FilgraphManager graphManager = new FilgraphManager(); graphManager.RenderFile(openFileDialog.FileName); // Attach the view to a picture box on the form. try { videoWindow = (IVideoWindow)graphManager; videoWindow.Owner = (int)pictureBox1.Handle; videoWindow.WindowStyle = WS_CHILD | WS_CLIPCHILDREN; videoWindow.SetWindowPosition( pictureBox1.ClientRectangle.Left, pictureBox1.ClientRectangle.Top, pictureBox1.ClientRectangle.Width, pictureBox1.ClientRectangle.Height); } catch { // An error can occur if the file does not have a video // source (for example, an MP3 file). // You can ignore this error and still allow playback to // continue (without any visualization). } // Start the playback (asynchronously). mc = (IMediaControl)graphManager; mc.Run(); } } </code></pre> <p>I want this to work</p> <pre><code>this.progressBar2.Value =(int) m.CurrentPosition; </code></pre> <p>but it doesn't work.</p>

    1. COIt appears that you don't know how to handle basic casting and this project may be a bit above your head. I would recommend reading through a C# book or guide.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
