    <p>I have 48 frames/images. What i did that when i click play(button14) it will move through the images automatic.</p> <p>But i also want that the trackBar Bar will move togeather with the timer. But if i make TrackBar1.Value = _indx; in the timer3 tick event then after some times when its doing play over and over again the value of the trackBar change if i had 48 frames so now the trackBar have only 15 ticks and then it stop when its getting to the end on the right.</p> <p>What i want is that if i click play it will run through the images over and over again also if i clicked pause and then continue untill i make stop.</p> <p>In fact the trackBar value change since in the timer3 tick event i also do _indx++; and when its 15 frames on the trackBar it also stop in the end instead of continue.</p> <pre><code>private void btnPlay_Click(object sender, EventArgs e) { _indx = 0; DirectoryInfo dir = new DirectoryInfo(sf); if (_files == null) _files = new List&lt;FileInfo&gt;(); FileInfo[] fi = dir.GetFiles("*.bmp"); _files.AddRange(fi); _files = _files.OrderBy(f =&gt; f.LastWriteTime).ToList(); button14.ForeColor = Color.Red; button13.ForeColor = Color.Black; button12.ForeColor = Color.Black; timer3.Start(); button13.Enabled = true; button13.Text = "Pause"; button12.Enabled = true; } private void timer3_Tick(object sender, EventArgs e) { try { Image iOLd = this.pictureBox1.Image; Image img = Image.FromFile(_files[_indx].FullName); trackBar1.Value = _indx; label23.Text = _files[_indx].Name; this.pictureBox1.Image = img; if (iOLd != null) iOLd.Dispose(); _indx++; if (_indx &gt;= _files.Count) _indx = 0; timer3.Interval = 10; timer3.Start(); } catch { } } private void btnPause_Click(object sender, EventArgs e) { button13.ForeColor = Color.Red; button14.ForeColor = Color.Black; timer3.Stop(); if (button13.Text == "Continue") { timer3.Start(); button13.Text = "Pause"; return; } if (button13.Text == "Pause") { timer3.Stop(); button13.Text = "Continue"; } } private void btnStop_Click(object sender, EventArgs e) { trackBar1.Value = 0; Image iOLd = this.pictureBox1.Image; Image img = Image.FromFile(_files[0].FullName); this.pictureBox1.Image = img; if (iOLd != null) iOLd.Dispose(); button13.Text = "Pause"; timer3.Stop(); _indx = 0; label23.Text = _files[_indx].Name; button12.ForeColor = Color.Red; button14.ForeColor = Color.Black; button13.Enabled = false; } </code></pre> <p>Button14 is Play button13 is Pause/Continue and Button12 is Stop The problem is that if i dont make trackBar1.Value = _indx; the trackBar wont move at all. And if i dont make _indx++; then nothing will work.</p> <p>_files is List and _indx is int</p>

    2. COSolved it by making a new instance of the _files List each time i click play and also added a new line in the timer3 tick inside the if _indx >= _files.count then also make trackBar1.Value = 0;

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.
