Having a problem with DLL trying to return several values. Please help.

[Vladimir]

For some reason, my indicator crashed when I try to return several values through a DLL. Currently in my DLL I have something like this

MT4_EXPFUNC void __stdcall myDLL(const double x, const double y, double& sum, double& product)

{

sum=x+y;

product=x*y;

}

In my mq4 code, I have

#import "myDLL.dll"
void myDLL(double x, double y, double& sum, double& product);
#import

int start()
{

double x=2.0;

double y=3.0;

double sum,product;

myDLL(x,y,sum,product);

}

The terminal crashes when I try to run this. It also crashes if I change the mq4 code to

#import "myDLL.dll"
void myDLL(double x, double y, double sum, double product);
#import

int start()
{

double x=2.0;

double y=3.0;

double sum,product;

myDLL(x,y,sum,product);

}

Where is my mistake?

Hmmm, believe I had the same problem... returned an array instead.

check: 'MySQL wrapper'

I guess the solution is in there.
