Taskbar Peripheral Status Sample

Taskbar Peripheral Status Sample

Demonstrates taskbar icon overlays and progress bars.

This topic contains the following sections.


This sample creates an example taskbar button on which it demonstrates the use of ITaskbarList3::SetOverlayIcon by allowing you to apply various overlays chosen from a menu.

The sample also provides the option of simulating a progress indicator on the button, demonstrating the use of ITaskbarList3::SetProgressState and ITaskbarList3::SetProgressValue by showing at first an indeterminate progress indicator (TBPF_INDETERMINATE), and then a normal proportional indicator (TBPF_NORMAL).
