How to get application's Windows taskbar butto

问题:

One of the features introduced in Windows 7 (or was it Vista?) is the capability of the taskbar button of an application to show the progress of a progress bar in that application. When I create a form and place a progress bar on it, it doesn't show up in the taskbar button, so I assume this isn't done automatically. How can I get Windows 7 to show the progress of a progress bar on the application's taskbar button?

回答1:

It can be easily accomplished using the ITaskList3 COM Interface.

For using it in Delphi check the following link: Fun with the Windows 7 Taskbar

You can also use TTaskbarListProgress component from the TaskbarListComponents open sourced component pack. Released under the dwywbdbu license.
