[QUOTE="EDN Admin, post: 797700, member: 20559"] I have this click button event where i start the timer3: <pre class="prettyprint private void button5_Click(object sender, EventArgs e) { _indx = 0; if (HistogramLoadedFile == true) { DirectoryInfo dir = new DirectoryInfo(directoryName); if (_files == null) _files = new List<FileInfo>(); FileInfo[] fi = dir.GetFiles("*.bmp"); _files.AddRange(fi); _files = _files.OrderBy(f => f.LastWriteTime).ToList(); button5.ForeColor = Color.Red; button6.ForeColor = Color.Black; button7.ForeColor = Color.Black; timer3.Start(); button6.Enabled = true; button6.Text = "Pause"; button7.Enabled = true; } else { DirectoryInfo dir = new DirectoryInfo(subDirectoryName); if (_files == null) _files = new List<FileInfo>(); FileInfo[] fi = dir.GetFiles("*.bmp"); if (fi.Length == 0) { fi = _fi; } _files.AddRange(fi); _files = _files.OrderBy(f => f.LastWriteTime).ToList(); button5.ForeColor = Color.Red; button6.ForeColor = Color.Black; button7.ForeColor = Color.Black; timer3.Start(); button6.Enabled = true; button6.Text = "Pause"; button7.Enabled = true; } }[/code] And then the timer3 tick event: <pre class="prettyprint private void timer3_Tick(object sender, EventArgs e) { //timer3.Stop(); try { Image iOLd = this.pictureBox1.Image; Image img = Image.FromFile(_files[_indx].FullName); myTrackPanelss1.trackBar1.Value = _indx; label22.Text = _files[_indx].Name; this.pictureBox1.Image = img; if (iOLd != null) iOLd.Dispose(); _indx++; if (_indx >= _files.Count) _indx = 0; timer3.Interval = 10; timer3.Start(); } catch { } }[/code] The timer interval is set to 10. So why its moving so slow ? And why in the end the timer stop ? The end i mean when the trackBar1 slider get to the end. Instead of repeating and keep playing it stop i dont understand why. Two strange things. And this is the only place i set in my code the timer3 interval. 1. Why its slow ? 2. Why it stop in the end ? And the variable _files contain 2255 files(indexs) inside. <hr class="sig danieli [url=http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/82fd9204-872a-4de1-b444-3f663db9e162]View the full article[/url] [/QUOTE]
