TB_BUTTONSTRUCTSIZE

  • Artigo

A version of this page is also available for

Windows Embedded CE 6.0 R3

4/8/2010

This message specifies the size of the TBBUTTON structure.

Syntax

TB_BUTTONSTRUCTSIZE wParam = (WPARAM) cb; 
    lParam = 0;

Parameters

  • cb
    Size, in bytes, of the TBBUTTON structure.
  • lParam
    Not used.

Return Value

None.

Remarks

The system uses the size to determine which version of the common control dynamic-link library (DLL) is being used.

If an application uses the CreateWindowEx function to create the toolbar, the application must send this message to the toolbar before sending the TB_ADDBUTTONS or TB_INSERTBUTTON message. The CreateToolbarEx function automatically sends TB_BUTTONSTRUCTSIZE, and the size of the TBBUTTON structure is a parameter of the function.

Requirements

Header commctrl.h
Windows Embedded CE Windows CE 1.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
