UNICODE字符串互转:

 

//-------------------------------------------------------------------------------------
  //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]));
