SECTab::m_pExtra
void* SECTab::m_pExtra
This member stores an opaque pointer to an optional user-defined buffer. If you would like to associate some user-defined data with each tab in a tab control, you can accomplish this by setting this member to point to that data. Alternatively, you might prefer to derive your own class from SECTab. The same can be accomplished in this way, but you avoid the hassle of creating an extra structure if more than one extra data member is required.
