I have already changed it. I do not have the type long in my code, just NativeLong, but it does not work. My Structure class is correct? My pointers are correct? Is it possible to use JNA with any DLL? Thank so much!!!

to post the signatures of java functions and the C++ function, for comparasion. I cannot see the errors, the type mapping is correct? I do not get compiler errors and do not get execution error, just does not work.

C signatures

int Initialize_HL(PCHAR BoardID,void ** hDev); int K_Move_Data_HL(void ** hDev,BOOL RW,unsigned short Nb_Words, unsigned short * Buffer,signed long DSPAddress, int MemSpace,char * Symbol,struct HSymTbl SymTable);

LoadUser_HL(void ** hDev,char * FilePath,struct HSymTbl * pSymTable);

Java Assignatures:

public interface SignalRangerInterface extends Library { public int Initialize_HL(String boardId, PointerByReference hDev); public int LoadUser_HL(PointerByReference hDev, String filePath, SignalRanger.HSymTbl pSymTable); public int K_Move_Data_HL(PointerByReference hDev, int rw, short nbWords, short[] buffer, long dSPAdrress, int memSpace, String symbol, SignalRanger.HSymTbl.ByValue symTable);

Change long to NativeLong for DSPAddress.

public int ExecUser_HL(PointerByReference hDev, long dSPAddress, String symbol, SignalRanger.HSymTbl.ByValue pSymTable);

Ditto here.
