Parameters

NameDescription
hToolbarHandle to the toolbar control.
cbSize, in bytes, of the TBBUTTON structure.

Description

Specifies the size of the TBBUTTON structure.

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 CreateWindowExW function to create the toolbar, the application must send this message to the toolbar before sending the TB_ADDBITMAP or TB_ADDBUTTONS message.
