DLL help

[ZeRider]

Hi,
Could someone help me translate this C++ code with DLL into HTBasic ?

1/ The C++ original is :

SESSION sessionID; /// Handles current session
DWORD cardNum; /// Card’s logical number
char ID_String[100]; /// Holds string of a card

/// The Function obtains identification string of a specified card
/// The function retrievs information of card’s “Model name, serialNum, firmwareRevisison”
status = PIPLX_CardId(sessionID, cardNum, ID_String, sizeof(ID_String));

2/ My actual HTBasic nonfunctional translate is :

LONG Status
LONG Session
LONG Card
INTEGER Size

DIM Data$(1:100)[1] ! <— I think the issue is on these 2 parameters …
Size=SIZE(Data$,1) ! =100
!
DLL GET “STDCALL LONG Piplx_w32:_PIPLX_CardId@16” AS “Identity”
Status=FNIdentity((Session),(Card),Data$(1),(Size))

Here is the function description, if that could help …

PIPLX_CardId

unsigned long PIPLX_CardId (long session, unsigned long cardNumber, char cardID[], unsigned long length);

Purpose
Obtains the identification string of the specified card. The string contains these elements:
“model code;serial number;revision code”
The <revision code> value represents the hardware version of the unit – cards have no firmware on-board.

Parameters

Session/ Type/ Description
Input/ long /Handle of current session.

cardNumber/ Type/ Description
Input/ unsigned long/ Card number.

length/ Type/ Description
Input/ unsigned long/ Length of character string buffer.

CardID/ Type/ Description
Output/ char []/ Identification string of the specified card. The string contains these elements:
“model code;serial number;revision code”
The <revision code> value represents the hardware version of the unit – cards have no firmware on-board.

Return Value/ Type/ Description
Return/ unsigned long/ Zero for success, or no-zero error code.

Solution found !!!

Size=100
ALLOCATE Data$[Size]
!
DLL GET “STDCALL LONG Piplx_w32:_PIPLX_CardId@16” AS “Identity”
Status=FNIdentity((Session),(Card),Data$,(Size))
