EnumWindows Function
The EnumWindows function enumerates all top-level windows on the screen by passing the handle to each window, in turn, to an application-defined callback function. EnumWindows continues until the last top-level window is enumerated or the callback function returns FALSE.
Syntax
BOOL EnumWindows(
WNDENUMPROC lpEnumFunc,
LPARAM lParam
);
Parameters
lpEnumFunc
[in] Pointer to an application-defined callback function. For more information, see EnumWindowsProc.
lParam
[in] Specifies an application-defined value to be passed to the callback function.
Return Value
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
If EnumWindowsProc returns zero, the return value is also zero. In this case, the callback function should call SetLastError to obtain a meaningful error code to be returned to the caller of EnumWindows.
Remarks
The EnumWindows function does not enumerate child windows, with the exception of a few top-level windows owned by the system that have the WS_CHILD style.
This function is more reliable than calling the GetWindow function in a loop. An application that calls GetWindow to perform this task risks being caught in an infinite loop or referencing a handle to a window that has been destroyed.
lpEnumFunc must be the address returned by JNative.createCallback()

throws NativeException,
java.lang.IllegalAccessException
RegisterClass Function
The RegisterClass function registers a window class for subsequent use in calls to the CreateWindow or CreateWindowEx function.
The RegisterClass function has been superseded by the RegisterClassEx function. You can still use RegisterClass, however, if you do not need to set the class small icon.
Syntax
ATOM RegisterClass(
CONST WNDCLASS *lpWndClass
);
Parameters
lpWndClass
[in] Pointer to a WNDCLASS structure. You must fill the structure with the appropriate class attributes before passing it to the function.
Return Value
If the function succeeds, the return value is a class atom that uniquely identifies the class being registered. This atom can only be used by the CreateWindow, CreateWindowEx, GetClassInfo, GetClassInfoEx, FindWindow, FindWindowEx, and UnregisterClass functions and the IActiveIMMap::FilterClientWindows method.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

NativeException
public static LONG LoadIcon(LONG hInstance,
java.lang.String lpIconName)
throws NativeException,
java.lang.IllegalAccessException
HICON LoadIcon(
HINSTANCE hInstance,
LPCTSTR lpIconName
);
Parameters
hInstance
[in] Handle to an instance of the module whose executable file contains the icon to be loaded. This parameter must be NULL when a standard icon is being loaded.
lpIconName
[in]
Pointer to a null-terminated string that contains the name of the icon resource to be loaded. Alternatively, this parameter can contain the resource identifier in the low-order word and zero in the high-order word. Use the MAKEINTRESOURCE macro to create this value.
To use one of the predefined icons, set the hInstance parameter to NULL and the lpIconName parameter to one of the following values.
IDI_APPLICATION
Default application icon.
IDI_ASTERISK
Same as IDI_INFORMATION.
IDI_ERROR
Hand-shaped icon.
IDI_EXCLAMATION
Same as IDI_WARNING.
IDI_HAND
Same as IDI_ERROR.
IDI_INFORMATION
Asterisk icon.
IDI_QUESTION
Question mark icon.
IDI_WARNING
Exclamation point icon.
IDI_WINLOGO
Windows logo icon. Windows XP: Default application icon.
IDI_SHIELD
Security Shield icon.
Return Value
If the function succeeds, the return value is a handle to the newly loaded icon.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.

NativeException
java.lang.IllegalAccessException
public static LRESULT SendMessage(HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam)
throws NativeException,
java.lang.IllegalAccessException
SendMessage Function
The SendMessage function sends the specified message to a window or windows. It calls the window procedure for the specified window and does not return until the window procedure has processed the message.
To send a message and return immediately, use the SendMessageCallback or SendNotifyMessage function. To post a message to a thread's message queue and return immediately, use the PostMessage or PostThreadMessage function.
Syntax
LRESULT SendMessage(
HWND hWnd,
UINT Msg,
WPARAM wParam,
LPARAM lParam
);
Parameters
hWnd
[in] Handle to the window whose window procedure will receive the message. If this parameter is HWND_BROADCAST, the message is sent to all top-level windows in the system, including disabled or invisible unowned windows, overlapped windows, and pop-up windows; but the message is not sent to child windows.
Msg
[in] Specifies the message to be sent.
wParam
[in] Specifies additional message-specific information.
lParam
[in] Specifies additional message-specific information.
Return Value
The return value specifies the result of the message processing; it depends on the message sent.
