  //Description:

  // This function maps a character string to a wide-character (Unicode) string

  //

  //Parameters:

  // lpcszStr: [in] Pointer to the character string to be converted

  // lpwszStr: [out] Pointer to a buffer that receives the translated string.

  // dwSize: [in] Size of the buffer

  //

  //Return Values:

  // TRUE: Succeed

  // FALSE: Failed

  //

  //Example:

  // MByteToWChar(szA,szW,sizeof(szW)/sizeof(szW[0]));

  //---------------------------------------------------------------------------------------
