 EN_CHANGE

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.

    LRESULT CALLBACK WindowProc(
      HWND hwnd,       // handle to window
      UINT uMsg,       // WM_COMMAND
      WPARAM wParam,   // edit control identifier, EN_CHANGE
      LPARAM lParam    // handle to edit control (HWND)
    );

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.

Remarks

Rich Edit: 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.
