IsWindowUnicode

The IsWindowUnicode function determines whether the specified window is a native Unicode window.

BOOL IsWindowUnicode(

HWND hWnd
// handle of window
);

Parameters

hWnd

Identifies the window.

Return Values

If the window is a native Unicode window, the return value is nonzero.

If the window is not a native Unicode window, the return value is zero.

Remarks

The system does automatic two-way translation (Unicode to ANSI-ASCII) for window messages. For example, if an ANSI-ASCII window message is sent to a Unicode window, the system translates that message into a Unicode message before calling the window procedure. The system calls the IsWindowUnicode function to determine whether to translate the message.

When this function returns FALSE, the window is a native ANSI-ASCII window.
