 WM_ICONERASEBKGND

Windows NT 3.51 and earlier: The WM_ICONERASEBKGND message is sent to a minimized window when the background of the icon must be filled before painting the icon. A window receives this message only if a class icon is defined for the window; otherwise, WM_ERASEBKGND is sent. This message is not sent by newer versions of Windows.

Parameters

• wParam
Handle to the device context of the icon.
• lParam
This parameter is not used.

Return Value

An application should return nonzero if it processes this message.

Remarks

Windows NT 3.51 and earlier: The DefWindowProc function fills the icon background with the class background brush of the parent window. On newer versions of Windows, the DefWindowProc function ignores the message.

Notification Requirements

• Minimum DLL Version None
• Header Declared in Winuser.h, include Windows.h
• Minimum operating systems Windows 95, Windows NT 3.1
