ToolbarWindow32

The window class name for a toolbar control is TOOLBARCLASSNAME, which is defined as "ToolbarWindow32" in Commctrl.h.

CreateWindowEx creates an empty toolbar that you fill by sending a TB_ADDBUTTONS message, specifying the address of a TBBUTTON structure.

If you use the CreateWindowEx function to create a toolbar, you must send the TB_BUTTONSTRUCTSIZE message before adding any buttons. The message passes the size of the TBBUTTON structure to the toolbar.
