EnableWindow
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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
