IMenuButton::SetButtonState method (mmc.h)

The IMenuButton::SetButtonState method enables a user to change the state of a menu button.

Syntax

HRESULT SetButtonState(
  [in] int              idCommand,
  [in] MMC_BUTTON_STATE nState,
  [in] BOOL             bState
);

[in] idCommand

A value that specifies a user-supplied value that uniquely identifies the menu button in which the state is being changed.

[in] nState

A value that specifies the state of the button. This value can be one of the following values taken from the MMC_BUTTON_STATE enumeration:

The button accepts user input. A button that does not have this state does not accept user input and appears dimmed.

The button is not visible and cannot receive user input.

[in] bState

A value that specifies whether the state is to be turned on or off. TRUE indicates that the button state is on; otherwise, set to FALSE.

This method can return one of these values.
