The following code example uses the DrawVerticalChunks method in a Timer.Tick event handler to draw each increment of a progress bar. This code example is part of a larger example provided for the ProgressBarRenderer class.
// Handle the timer tick; draw each progressively larger rectangle. private void progressTimer_Tick(Object myObject, EventArgs e) { if (ticks < NumberChunks) { using (Graphics g = this.CreateGraphics()) { ProgressBarRenderer.DrawVerticalChunks(g, progressBarRectangles[ticks]); ticks++; } } else { progressTimer.Enabled = false; } }
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
