You can also set button states using the nStyle parameter; however, because button states are controlled by the ON_UPDATE_COMMAND_UI handler, any state you set using SetButtonStyle will be lost during the next idle processing. See How to Update User-Interface Objects and TN031: Control Bars for more information. |
