This message sets the number of bytes per tab reserved for application-defined data in a tab control. You can send this message explicitly or by using the TabCtrl_SetItemExtramacro.
Syntax
TCM_SETITEMEXTRA wParam = (WPARAM)(int) cb; lParam = 0; |
Parameters
- cb
-
Number of extra bytes.
- lParam
-
Not used.
Return Value
TRUE indicates success. FALSE indicates failure.
Remarks
By default, the number of extra bytes is four. An application that changes the number of extra bytes cannot use the TCITEMstructure to retrieve and set the application-defined data for a tab. Instead, you must define a new structure that consists of the TCITEMHEADERstructure followed by application-defined members.
Requirements
Header | commctrl.h |
Windows Embedded CE | Windows CE 1.0 and later |
Windows Mobile | Windows Mobile Version 5.0 and later |
