MaskedTextBox overrides its base control's implementation of ProcessKeyMessage to properly handle character events when the user is entering characters using an Input Method Editor (IME), such as is used for entering Japanese, Chinese, and other complex non-Latin scripts. ProcessKeyMessage detects any WM_CHAR messages that occur after it receives a WM_IME_CHAR message and suppresses them in order to prevent these characters from showing up in the control. If you derive from this control and override this message, you should duplicate this behavior if you wish your new control to work with IMEs.
