TabCtrl_SetItemExtra info  Overview  Group

The TabCtrl_SetItemExtra macro sets the number of bytes per tab reserved for application-defined data in a tab control. You can use this macro or explicitly send the TCM_SETITEMEXTRA message.

BOOL TabCtrl_SetItemExtra(

    HWND hwnd,

    int cb



Handle to the tab control.
Number of extra bytes.

Return Values

Returns TRUE if successful or FALSE otherwise.


By default, the number of extra bytes is four. An application that changes the number of extra bytes cannot use the TC_ITEM structure to retrieve and set the application-defined data for a tab. Instead, you must define a new structure that consists of the TC_ITEMHEADER structure followed by application-defined members.

An application should only change the number of extra bytes when a tab control does not contain any tabs.
