Header Control (MSAA UI Element Reference)

Note  This topic describes Header Control objects for purposes of MSAA UI Element Reference. How to create Header Control objects in various UI frameworks is not described here. See the API reference documentation for the UI framework you're using.

The window class name for a header control is WC_HEADER, which is defined as "SysHeader32" in Commctrl.h.
