Problem passing an array

[jkepler]

Hi,

I have the following problem: I have a routine in C/C++ (compiled in a DLL) in the form of:


void function1(double rrd[],...){...}


I want to pass an array from VB6 to that routine. So I have the following routine in VB6:


Private Sub function1 Lib "test.dll" (ByRef rrd as double,...)


and I call it:


Dim dat(6)
...
Call function1(dat(0),...)


The problem is that when I call it from VB6 I get always an error - VB6 crashes.

Any suggestions?

Kind regards,

JKepler

your array have six elements from 0 to 5 but you put only first element to pass method and first element is not an array then crash is your result

Hi,

How should I solve the problem then? Pass the values one by one? What if the array has 200 elements?

Kind regards,

pass all elements if the method parameter is an array.I don't know VB so I write in c++


void FunctionSample(double arDouble[])
{

}
void Main()
{
double arDoubles[] = double[10];
FunctionSample(arDoubles[0]);//it's wrong. we should pass an array not an element of array.
FunctionSample(arDoubles);//error solved. we passed an array and work perfectly.
}
