Question about DLLStructCreate

[Jango]

Hello,

I want to create these structures with DLLStructCreate, the first structure is included in the second. How to do that with DLLStructCreate ?

typedef struct {
BYTE certif[];
long certifLength;
char certifLabel[];
long certifStatus;
} BEID_Certif;

typedef struct {
long usedPolicy;
BEID_Certif certificates[]; // <-- ARRAY of BEID_Certif 1st struct
long certificatesLength;
long signatureCheck;
} BEID_Certif_Check;

One more question, i also noticed that there is a type BOOL but i cant' find it in the autoit help file, so what can i use instead ?

[weaponx]

Boolean should be the same as Int.

Boolean should be the same as Int.

Thank you weaponx... what about my first question ?

I don't believe you can create a dynamic arrays like "BYTE certif[...]" or "char certifLabel[...]". You need to know the sizes of these variables in order to create your structs. It appears that the certif[] size is provided by the certifLength variable, but its impossible to know where that variable is located in memory because it comes after the certif data. Can you provide the documentation for these structs?

the lenght of the array are fixed, for example BEID_MAX_CERT_LEN is a constant. here it is:

#define BEID_MAX_CERT_LEN                           2048
#define BEID_MAX_CERT_NUMBER                     10
#define BEID_MAX_CERT_LABEL_LEN              256


typedef struct 
{
    BYTE certif[BEID_MAX_CERT_LEN];
    long certifLength;              
    char certifLabel[BEID_MAX_CERT_LABEL_LEN+1];
    long certifStatus;                  
    BYTE rfu[6];
} BEID_Certif;

typedef struct 
{
    long usedPolicy;                    
    BEID_Certif certificates[BEID_MAX_CERT_NUMBER];
    long certificatesLength;            
    long signatureCheck;                   
    BYTE rfu[6];
} BEID_Certif_Check;

Normally, you would do it this way:

$BEID_Certif = "BYTE certif[2048]; long certifLength; char certifLabel[256+1]; long certifStatus; BYTE rfu[6]"
$BEID_Certif_Check = "long usedPolicy; " & $BEID_Certif & "; long certificatesLength; long signatureCheck; BYTE rfu[6]"

But here, It is used as an Array ... Don't know, how a Struct is used as Array in a Struct. Possibly you can't to it in AutoIt

Const $BEID_MAX_CERT_LEN =  2048
Const $BEID_MAX_CERT_NUMBER = 10
Const $BEID_MAX_CERT_LABEL_LEN = 256

$sBEID_Certif = "byte[" & $BEID_MAX_CERT_LEN & "];long CertifLength;char [" & $BEID_MAX_CERT_LABEL_LEN+1 & "];long CertifStatus;byte rfu[6]"

$sBEID_Certif_Check = "long UsedPolicy;"
For $i = 1 To $BEID_MAX_CERT_NUMBER
    $sBEID_Certif_Check &= $sBEID_Certif & ";"
Next
$sBEID_Certif_Check &= "long CertificatesLength;long SignaturesCheck;byte rfu[6]"

$tBEID_Certif_Check = DllStructCreate($sBEID_Certif_Check)

well, you are a god Siao ... thank you !
