get/put(VARIANT newVal) ??

[komofilms]

Hello guys!

Im new in C++ programing, and I want to
get and put same data in my COM.
I dont have problems with basic data types.

My IDL:

[propget, id(FW_DISPID_OFFSET), helpstring("property Offset")] HRESULT Offset([out, retval] short *pVal);
[propput, id(FW_DISPID_OFFSET), helpstring("property Offset")] HRESULT Offset([in] short newVal);

My Cpp:

STDMETHODIMP CYslider::get_Offset(short *pVal)
{
*pVal = m_Offset;
return S_OK;
}

STDMETHODIMP CYslider::put_Offset(short newVal)
{
m_Offset = newVal;
SetDirty(TRUE);
FireViewChange();
return S_OK;
}

So far so good :), but now I dont know how to deal with arrays,
I googled a lot and I have found that solution is with VARIANT and safearray
but I dont know how to fill STDMETHODIMP for array.

My IDL:

[propget, id(FW_DISPID_ARRAYTEST), helpstring("property ArrayTest")] HRESULT ArrayTest([out, retval] VARIANT *pVal);
[propput, id(FW_DISPID_ARRAYTEST), helpstring("property ArrayTest")] HRESULT ArrayTest([in] VARIANT newVal);

My Cpp:

STDMETHODIMP CYslider::get_ArrayTest(VARIANT *pVal)
{
????????????????????????????????
return S_OK;
}

STDMETHODIMP CYslider::put_ArrayTest(VARIANT newVal)
{
????????????????????????????????
return S_OK;
}

I will be very happy if somebody could help me, with example, advice...

Bye,
Komofilms

If you did your googling then you had to come across this article. It illustrates an array of BSTRs, but the syntax is nearly the same for any POD (plain-old-data) type.
