Salve,
Dovrei tradurre un sorgente scritto in C collegandomi ad una DLL in xHarbour e FWH 9.05. Ho usato la classe tStruct (non so se nel corso del tempo ha subito cambiamenti),
ma il risultato è che non riesco a collegarmi al device. Qualcuno mi saprebbe indicare la soluzione
Grazie
typedef struct
{
char IPAddress[16]; //xxx.xxx.xxx.xxx
int Port;
} TETHParameters;
typedef struct
{
char Amount[8+1];
char ECRId[8+1];
char PaymentType[1+1];
char TerminalId[8+1];
} TECRData;
typedef struct
{
char TerminalId[8+1];
char AcquirerId[11+1];
char TransactionType[3+1];
char TransactionResult[2+1];
} TPOSData;
TETHParameters ETHParameters;
strcpy(ETHParameters.IPAddress, “192.168.1.2”);
ETHParameters.Port = 1234;
IAE17AX_InitEth(ÐParameters);
TECRData ECRData;
TPOSData POSData;
int TransactionResult;
strcpy(ECRData.Amount, “00000001”);
strcpy(ECRData.PaymentType, “0”);
strcpy(ECRData.ECRId, “12345678”);
strcpy(ECRData.TerminalId, “87654321”);
TransactionResult = IAE17AX_Payment(&ECRData, &POSData);
ECRData e POSData sono puntatori alle strutture
