处理EN_CHANGE消息

--------------------------------------------------------------------------------

The EN_CHANGE notification message is sent when the user has taken an action that may have altered text in an edit control. Unlike the EN_UPDATE notification message, this notification message is sent after the system updates the screen. The parent window of the edit control receives this notification message through a WM_COMMAND message.

Syntax

EN_CHANGE

WPARAM wParam
LPARAM lParam;
Parameters

wParam
The low-order word specifies the edit control identifier.
The high-order word specifies the notification message.

lParam
Handle to the edit control.
Return Value

No return value.
Remarks

Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. To receive EN_CHANGE notifications, specify ENM_CHANGE in the mask sent with the EM_SETEVENTMASK message. For information about the compatibility of rich edit versions with the various system versions, see About Rich Edit Controls.

The EN_CHANGE notification is not sent when the ES_MULTILINE style is used and the text is sent through WM_SETTEXT.

Notification Requirements

Minimum DLL Version None
Header Declared in Winuser.h, include Windows.h
Minimum operating systems Windows 95, Windows NT 3.1

EN_UPDATE Notification

--------------------------------------------------------------------------------

The EN_UPDATE notification message is sent when an edit control is about to redraw itself. This notification message is sent after the control has formatted the text, but before it displays the text. This makes it possible to resize the edit control window, if necessary. The parent window of the edit control receives this notification message through a WM_COMMAND message.

Syntax

EN_UPDATE

WPARAM wParam
LPARAM lParam;
Parameters

wParam
The low-order word specifies the edit control identifier.
The high-order word specifies the notification message.

lParam
Handle to the edit control.
