#Include <WinAPIEx.au3>
_WinAPI_CallWindowProcW ( $pPrevWndProc, $hWnd, $iMsg, $wParam, $lParam )

参数

$pPrevWndProc The address of a previous window procedure, or a special internal value meaningful only to
_WinAPI_CallWindowProcW() function.
$hWnd A handle to the window procedure that received the message.
$iMsg The message.
$wParam Additional message-specific information. The content of this parameter depends on the message.
$lParam Additional message-specific information. The content of this parameter depends on the message.

返回值

Success The result of the message processing and depends on the message sent.
失败: 返回 0 并设置 @error 标志为非 0 值.

注意/说明

Use this function for window subclassing. Usually, all windows with the same class share one window procedure.
A subclass is a window or set of windows with the same class whose messages are intercepted and processed by
another window procedure (or procedures) before being passed to the window procedure of the class.

The _WinAPI_CallWindowProcW() function handles Unicode-to-ANSI conversion. You cannot take advantage
of this conversion if you call the window procedure directly.
