BCGControlBar Pro for MFC
BOOL CBCGPColorButton::m_bEnabledInCustomizeMode

Indicates whether the color button is enabled in customization mode.

Set this member to TRUE to enable the color button in customization mode.

For example, if you need to put a color button on a customization dialog's page (or allow the user another color selection during customization) you need to set the m_bEnabledInCustomizeMode to TRUE explicitly to enable the button.

By default this flag is set to FALSE for backward compatibility.
