MapVirtualKey

This function translates, or maps, a virtual-key code into a scan code or character value, or translates a scan code into a virtual-key code.

UINT MapVirtualKey( 
  UINT uCode, 
  UINT uMapType 
);

uMapType
[in] Specifies the translation to perform. The value of this parameter depends on the value of the uCode parameter

Value	Description
0	uCode is a virtual-key code and is translated into a scan code. If it is a virtual-key code that does not distinguish between left- and right-hand keys, the left-hand scan code is returned. If there is no translation, the function returns 0.
1	uCode is a scan code and is translated into a virtual-key code that does not distinguish between left- and right-hand keys. If there is no translation, the function returns 0.
2	uCode is a virtual-key code and is translated into an unshifted character value in the low-order word of the return value. Dead keys (diacritics) are indicated by setting the top bit of the return value. If there is no translation, the function returns 0.
3	uCode is a scan code and is translated into a virtual-key code that distinguishes between left- and right-hand keys. If there is no translation, the function returns 0.

A character value indicates success. Zero indicates that there is no translation.
