EN_CHANGE Notification

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.

    LPARAM lParam;

Parameters

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.
