7bit:
#import "yourdll.dll"
double DataCollection1(int para1, double para2, double para3, double &DataCollection1Return[]);
#import
and to call the function:
foobaz = DataCollection(foo, bar, baz, resDataCollection1);
The dll will receive a pointer to the first element of the array.
Thanks 7bit I got it. Thank you very much

I am in process of creating a dll. In a mql4 function I would like to pass 2 or more parameters, which will be called in a dll. And the dll function should return multiple parameters.
In this process I am passing a reference of an array resDataCollection1, which will store the data that is be returned.
Is this code correct??
MQL4 FUNCTION
double resDataCollection1[2]={0,0};DataCollection1(para1, para2, para3, &resDataCollection1);
DLL FUNCTION
MT4_EXPFUNC double __stdcall DataCollection1(int para1, double para2, double para3, double *DataCollection1Return)
{
// do some calculation
DataCollection1Return[0]=return1;
DataCollection1Return[1]=return2;
return 0;
}
