Using Blowfish algorythm with Crypto API

Hi! I got a key was generated by Blowfish algorythm then how can I use it
with Crypto API. The key length is 56 bytes and I had trouble with importing
it from CryptImportKey(). The error code I get back is 80090007.
Thanks for all the help from you guys.
Below are the code I'm using.

// Clean out the container that we want to use.
dwReturnCode = CryptAcquireContext(
&hCryptProv, // [out] HCRYPTPROV *phProv
"MyContainer", // [in] LPCTSTR pszContainer
MS_ENHANCED_PROV, // [in] LPCTSTR pszProvider
PROV_RSA_FULL, // [in] DWORD dwProvType
CRYPT_DELETEKEYSET); // [in] DWORD dwFlags

if(! dwReturnCode && GetLastError() != NTE_BAD_KEYSET)
{
printf("Error during CryptAcquireContext!\n");
return false;
}//endif
else
{
if (! CryptAcquireContext(
&hCryptProv, // [out] HCRYPTPROV *phProv
"MyContainer", // [in] LPCTSTR pszContainer
MS_ENHANCED_PROV , // [in] LPCTSTR pszProvider
PROV_RSA_FULL, // [in] DWORD dwProvType
CRYPT_NEWKEYSET)) // [in] DWORD dwFlags
{
printf("\nError during CryptAcquireContext!\n");
return false;
}//end if.
}//end else.

printf("Successfully calling CryptAcquireContext...\n");

dwDataLen = sizeof(BLOB_SessionKey);

// We now import the session key.
if(! CryptImportKey(hCryptProv, // [in] HCRYPTPROV hProv
BLOB_SessionKey, // [in] BYTE* pbData
dwDataLen, // [in] DWORD dwDataLen
0, // [in] HCRYPTKEY hPubKey
0, // [in] DWORD dwFlags
&hSessionKey)) // [out] HCRYPTKEY* phKey
{
printf("Error during CryptImportKey!\n");
HandleError("Import key error...");
return false;
}//endif

printf("Successfully calling CryptImportKey...\n");

Could anyone help me to find where I can get Blowfish files (.h, .cpp...)?
