EN_CHANGE notification code

  • Article

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

EN_CHANGE

    WPARAM wParam;
    LPARAM lParam;

Parameters

wParam

The LOWORD contains the identifier of the edit control. The HIWORD specifies the notification code.

lParam

A handle to the edit control.

Remarks

Rich Edit: Supported in Microsoft Rich Edit 1.0 and later. To receive EN_CHANGE notification codes, 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 code is not sent when the ES_MULTILINE style is used and the text is sent through WM_SETTEXT.
