Description

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).

Requirements

Product Minimum Product Version
Windows Windows 7
Windows Software Development Kit (SDK) 7.0

 

Downloading the Sample

This sample is available in the following locations.

Location Path URL
Code Gallery Windows Shell Integration Samples on Code Gallery
Windows 7 SDK Download Windows 7 SDK

 

In the case of the Windows SDK, once you have downloaded and installed it, you will find the samples in the installed directory. For example, use of the default installation path for the Windows 7 SDK results in this sample being placed under C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\WinUI\Shell\AppShellIntegration\TaskbarPeripheralStatus.

Building the Sample

To build the sample from the command prompt:

  1. Open the command prompt window and navigate to the TaskbarPeripheralStatus project directory.
  2. Enter msbuild PeripheralStatus.sln.

To build the sample using Microsoft Visual Studio (preferred):

  1. Open Windows Explorer and navigate to the TaskbarPeripheralStatus project directory.
  2. Double-click the icon for the PeripheralStatus.sln file to open the project in Visual Studio.
  3. From the Build menu, select Build Solution.

Running the Sample

  1. Navigate to the directory that contains the new executable file (for instance, C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\WinUI\Shell\AppShellIntegration\TaskbarPeripheralStatus\Win32\Debug), using the command prompt or Windows Explorer.

    • If using the command line, enter PeripheralStatus.exe.
    • If using Windows Explorer, double-click the icon for PeripheralStatus.exe.

    A new window will open, with an associated taskbar button.

  2. To demonstrate overlays, choose Overlay 1 or Overlay 2 from the window's Peripheral Status menu. The chosen overlay appears on the taskbar button. To remove the overlay, choose Clear Overlay.

  3. To demonstrate the progress bar, choose Simulate Progress from the window's Peripheral Status menu. The taskbar button will show an indeterminate progress indicator then switch to a normal indicator.

  4. Choose Exit from the window's File menu to end the program.
