ITaskbarList::SetActiveAlt method (shobjidl_core.h)

Marks a taskbar item as active but does not visually activate it.

Syntax

HRESULT SetActiveAlt(
  HWND hwnd
);

Parameters

hwnd

Type: HWND

A handle to the window to be marked as active.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

SetActiveAlt marks the item associated with hwnd as the currently active item for the window's process without changing the pressed state of any item. Any user action that would activate a different tab in that process will activate the tab associated with hwnd instead. The active state of the window's item is not guaranteed to be preserved when the process associated with hwnd is not active. To ensure that a given tab is always active, call SetActiveAlt whenever any of your windows are activated. Calling SetActiveAlt with a NULL hwnd clears this state.
