Specifies the size of the TBBUTTON structure.
Parameters
-
wParam
-
Size, in bytes, of the TBBUTTON structure.
-
lParam
- Must be zero.
Return value
No return value.
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_ADDBITMAP or TB_ADDBUTTONS message. The CreateToolbarEx function automatically sends TB_BUTTONSTRUCTSIZE, and the size of the TBBUTTON structure is a parameter of the function.
