ActiveX - custom method - Can I pass a vector<double> as a parameter 1

[joelwenzel]

I am creating an activeX control and I want to pass a vector containing a bunch of doubles. I know I can pass a pointer to an array of doubles but I would also like to be able to pass a vector from <vector.h>.

Is this possible? It is not in the 'Type ' drop down list.

Also, I want to test my control in the test container. The problem is that the method I wish to test requires that I pass an array of doubles to it. Is this possible in this test container?

In general, the way to pass a vector to a function expecting an array is to pass the address of the first element (assuming its not empty): &vec[0]

And vectors are in <vector>, not <vector.h>

 

[joelwenzel]

yeah , I know. <vector>

Anyway, I did not know that I could pass a vector as an array. That is a very useful tip. Thank you.

to pase some arrays you should pass a SAFEARRAY
