Hi,

I have Structure mapping poroblem. There is structures in structure.

I recieve CERT_CONTEXT structure (Structure wich consists of another Structures) from function, next step i need to use CERT_CONTEXT->CERT_INFO->CERT_PUBLIC_KEY_INFO structure in another function, but i have "An unexpected error has been detected by Java Runtime Environment" after calling it. I think i have incorrect structure mapping... There is my structures: // typedef struct _CERT_CONTEXT { // + DWORD dwCertEncodingType; // + BYTE * pbCertEncoded; // + DWORD cbCertEncoded; // + PCERT_INFO pCertInfo; // + HCERTSTORE hCertStore; }

public static class CERT_CONTEXT extends Structure { public DWORD dwCertEncodingType; public ByteByReference pbCertEncoded; public DWORD cbCertEncoded; public CERT_INFO pCertInfo; public HANDLE hCertStore; }

CERT_INFO is: // typedef struct _CERT_INFO { // DWORD dwVersion; // CRYPT_INTEGER_BLOB SerialNumber; // CRYPT_ALGORITHM_IDENTIFIER SignatureAlgorithm; // CERT_NAME_BLOB Issuer; // FILETIME NotBefore; // FILETIME NotAfter; // CERT_NAME_BLOB Subject; // CERT_PUBLIC_KEY_INFO SubjectPublicKeyInfo; // CRYPT_BIT_BLOB IssuerUniqueId; // CRYPT_BIT_BLOB SubjectUniqueId; // DWORD cExtension; // PCERT_EXTENSION rgExtension; // } CERT_INFO, *PCERT_INFO;

public class *CERT_INFO* extends Structure implements Structure.ByReference { public DWORD dwVersion; public CRYPT_DATA_BLOB SerialNumber; public CRYPT_ALGORITHM_IDENTIFIER SignatureAlgorithm; public CRYPT_DATA_BLOB Issuer; public Pointer NotBefore; public Pointer NotAfter; public CRYPT_DATA_BLOB Subject; public *CERT_PUBLIC_KEY_INFO* SubjectPublicKeyInfo; public CRYPT_BIT_BLOB IssuerUniqueId; public CRYPT_BIT_BLOB SubjectUniqueId; public DWORD cExtension; public CERT_EXTENSION rgExtension; // public static class ByReference extends CERT_EXTENSION implements // Structure.ByReference { // } } And CERT_PUBLIC_KEY_INFO is:

// typedef struct _CERT_PUBLIC_KEY_INFO { // CRYPT_ALGORITHM_IDENTIFIER Algorithm; // CRYPT_BIT_BLOB PublicKey; // } CERT_PUBLIC_KEY_INFO, *PCERT_PUBLIC_KEY_INFO; public class *CERT_PUBLIC_KEY_INFO* extends Structure { public *CRYPT_ALGORITHM_IDENTIFIER* Algorithm; public *CRYPT_BIT_BLOB* PublicKey; }

// typedef struct _CRYPT_ALGORITHM_IDENTIFIER { // LPSTR pszObjId; // CRYPT_OBJID_BLOB Parameters; // } CRYPT_ALGORITHM_IDENTIFIER, *PCRYPT_ALGORITHM_IDENTIFIER; public class *CRYPT_ALGORITHM_IDENTIFIER* extends Structure { public Pointer pszObjId; public *CRYPT_DATA_BLOB* Parameters; }

// typedef struct _CRYPT_BIT_BLOB { // DWORD cbData; // BYTE *pbData; // DWORD cUnusedBits; // } CRYPT_BIT_BLOB, *PCRYPT_BIT_BLOB; public class* CRYPT_BIT_BLOB* extends Structure { public DWORD cbData; public Pointer pbData; public DWORD cUnusedBits; }

// typedef struct _CRYPTOAPI_BLOB { // DWORD cbData; // BYTE *pbData; // } public class *CRYPT_DATA_BLOB* extends Structure { public DWORD cbData; public Pointer pbData; }
