hello together,
although my english is not very well i'd like to ask the experts what i do wrong with calling a function in a dll ...
i created a c-dll that includes the function SCORE ... this needs an indata and outdata array and does some calculating ...
-----------------------------------------------------------------------------------------------
CODE of th c-program:
#include <math.h>
#include <string.h>
#include <memory.h>
#include <ctype.h>
#include "neural_header.h"
#include "cscore.h"
#define csCLOSE indata[0].data.fnum
#define csCLOSE_1 indata[1].data.fnum
... and so on
#define csVOLUME_9 indata[74].data.fnum
#define csEM_PREDICTION outdata[0].data.fnum
#define csP_TARGET outdata[1].data.fnum
#define cs_WARN_ outdata[2].data.str
SFDKeyWords void __stdcall score( PARM *indata, PARM *outdata )
{
/*--- Auto Variables ---*/
double csH11;
double csH12;
.... and so on
double cs_NOCL_;
double cs_NTRIALS;
double cs_SUM_;
strcpy(cs_WARN_," ");
/*--- initialize stand alone formats library ---*/
#if FMTLIB == 1
xfinit();
#endif
cs_DM_BAD =0;
/** **************************/
/** writing the node intervaltargets */
/** **************************/
if ( cs_DM_BAD== 0)
{
csP_TARGET = 7.71649047510018;
/********************************/
/** end scoring code for neural*/
/********************************/
/*------------------------------------------------------------**/
/* tool: score node*/
/* type: assess*/
/* node: score*/
/*------------------------------------------------------------**/
/*------------------------------------------------------------**/
/* score: creating fixed names*/
/*------------------------------------------------------------**/
csEM_PREDICTION = csP_TARGET;
return;
}
usrNbucket usrnBuckets[]={
/* not used */
{0,0,0,NULL,NULL,' ',0.0}
};
usrCbucket usrcBuckets[]={
/* not used */
{NULL, NULL, 0, NULL}
};
usrFormat usrnFormats[] = {
{"**unused**",0.0,0,0,0,-1,-1,0}
};
usrFormat usrcFormats[] = {
{"**unused**",0.0,0,0,0,-1,-1,0}
};
int usrNumNfmts = 0;
int usrNumCfmts = 0;
--------------------------------------------------------------------
now i want to read the value outdata[1].data.fnum from metatrader and i include the dll and the function what works well ...
the following script code crashes the terminal and i have no idea what is happening, because i'm not a very good programmer ...
