Got It! Thanks (Again)

If I don't execute the LocalFree functions - memory leak.

If I do execute ALL the LocalFree functions - program dies.

Without my "LocalFree" problems - the program works perfectly.

I know I'm doing something stupid. There is some extraneous code in here
that is due to my testing. I left it in. Once again, Thank you in advance!

Here's the code.

CString CChildView::DecryptPOP3Password(BYTE* ppData, DWORD pBytes)
{
   // Get the hard drive's serial number - used for encryption purposes.
   CHardDriveInfo hardDriveInfo;
   hardDriveInfo.InitDriveInfo();
   CString strPassword;

   DATA_BLOB DataEntropy;
   DATA_BLOB DataOut;
   DATA_BLOB EncData;

   LPWSTR description;

   DataEntropy.pbData = (BYTE*)hardDriveInfo.HardDriveSerialNumber;
   DataEntropy.cbData = (DWORD)strlen((char*)
hardDriveInfo.HardDriveSerialNumber);

   EncData.cbData = pBytes;
   EncData.pbData = ppData;

   if(CryptUnprotectData(
        &EncData,
        &description,
        &DataEntropy,
        NULL,
        NULL,
        CRYPTPROTECT_LOCAL_MACHINE,
        &DataOut))
   {
      TRACE0("Successful\n");
       
   }
   else
   {
      TRACE0("Failed\n");
   }
   strPassword = DataOut.pbData;
           
   HLOCAL MyLocalMemory;
   DWORD LastError;
   MyLocalMemory = LocalFree(description); // This works fine
   if (NULL != MyLocalMemory)
      LastError = GetLastError();

   MyLocalMemory = LocalFree(DataOut.pbData); // This works fine
   if (NULL != MyLocalMemory)
      LastError = GetLastError();

   MyLocalMemory = LocalFree(&hardDriveInfo); // DOESN'T WORK
   if (NULL != MyLocalMemory)
   {
      LastError = GetLastError();
      TRACE1("failed with error %d", LastError);
   }
   MyLocalMemory = LocalFree(EncData.pbData); // THIS FAILS - CORRUPT
                                                 // HEAP - STOPS PROGRAM

   MyLocalMemory = LocalFree(DataEntropy.pbData);
   if (NULL != MyLocalMemory)
   {
      LastError = GetLastError();
      TRACE1("failed with error %d", LastError);
   }
   return strPassword;
}
