我想請問假設我開啟一個小算盤，能不能夠把裡頭的功能利用我寫的寫程式
把它 disable，不過我希望的 disable 是達到讓那個功能顏色變成灰階的的效果。
本來我是利用中間蓋一層透明的 Form 來做控制，不過結果不是很好。
打擾各位了，感謝各位不吝指教 ^____^

The EnableWindow function enables or disables mouse and keyboard input to the specified window or control. When input is disabled, the window does not receive input such as mouse clicks and key presses. When input is enabled, the window receives all input.
BOOL EnableWindow(
HWND hWnd, // handle to window
BOOL bEnable // flag for enabling or disabling input
);

Parameters
hWnd
Identifies the window to be enabled or disabled.
bEnable
Specifies whether to enable or disable the window. If this parameter is TRUE, the window is enabled. If the parameter is FALSE, the window is disabled.

Return Values
If the window was previously disabled, the return value is nonzero.
If the window was not previously disabled, the return value is zero. To get extended error information, call GetLastError.
Remarks
If the enabled state of a window is changing, a WM_ENABLE message is sent before the EnableWindow function returns. If a window is already disabled, all its child windows are implicitly disabled, although they are not sent a WM_ENABLE message.
A window must be enabled before it can be activated. For example, if an application is displaying a modeless dialog box and has disabled its main window, the application must enable the main window before destroying the dialog box. Otherwise, another window will receive the keyboard focus and be activated. If a child window is disabled, it is ignored when Windows tries to determine which window should receive mouse messages.
By default, a window is enabled when it is created. To create a window that is initially disabled, an application can specify the WS_DISABLED style in the CreateWindow or CreateWindowEx function. After a window has been created, an application can use EnableWindow to enable or disable the window.
An application can use this function to enable or disable a control in a dialog box. A disabled control cannot receive the keyboard focus, nor can a user gain access to it.

我看函式的解釋，他是把諸如滑鼠鍵盤對於某個特定的視窗，把這些事件 disable，不過我又再去
看看我原來PO的內容，是我描述不好(我其實只是想把某些我期望的功能給disable )，例如我開了
一個踩地雷好了，然後我的程式可以把踩地雷的假設 "遊戲->新遊戲" 這個功能給 disable (如果可以
把這個 menuitem 給灰階掉那效果更好)，謝謝你的回覆!!

編輯記錄

用shunchia63 的方法可以Enable和Disable一些窗口类控件（不能控制菜单项），但如果不做轮巡可能不能保证一直有效，因为原程序自己可能会去改变窗口的状态。补充办法就是Hook掉原程序的消息处理函数，这样就可以知道那些消息去使用控件了，不过不一定能令控件灰掉。
