TB_BUTTONSTRUCTSIZE (Windows CE 5.0)
This message specifies the size of the TBBUTTON structure.
TB_BUTTONSTRUCTSIZEwParam=(WPARAM)cb;lParam= 0;
Parameters
- cb
Size, in bytes, of the TBBUTTON structure. - lParam
Not used.
Return Values
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
OS Versions: Windows CE 1.0 and later.
Header: Commctrl.h.
