好的,试试这个(C++ ATL EXE 服务器):
[
object,
uuid(F7F8E65F-EBAD-4191-B916-2DB2A1EA0720),
dual,
nonextensible,
helpstring("IAofA Interface"),
pointer_default(unique)
]
interface IAofA : IDispatch{
[id(1), helpstring("method GetArray")] HRESULT GetArray([out,retval] VARIANT* pVals);
};
CComVariant CreateByteArrayAsVariant(BYTE *pData, ULONG size)
{
CComSafeArray<BYTE> sa(size);
for (ULONG i=0; i!=size; ++i)
{
sa.SetAt(i, pData[i]);
}
CComVariant var(sa);
return var;
}
STDMETHODIMP CAofA::GetArray(VARIANT* pVals)
{
CComSafeArray<VARIANT> sa(3);
BYTE a[] = {1};
BYTE b[] = {1, 2};
BYTE c[] = {3, 2, 1};
sa.SetAt(0, CreateByteArrayAsVariant(a, sizeof(a)));
sa.SetAt(1, CreateByteArrayAsVariant(b, sizeof(b)));
sa.SetAt(2, CreateByteArrayAsVariant(c, sizeof(c)));
CComVariant var(sa);
var.Detach(pVals);
return S_OK;
}
这是一个 VB.net 客户端:
Imports AofAServerLib
Module Module1
Sub Main()
Dim s As IAofA = New AofA
Dim a() = s.GetArray
For i As Integer = 0 To a.Length - 1
For j As Integer = 0 To a(i).Length - 1
Console.Write(a(i)(j))
Console.Write(" ")
Next
Console.WriteLine()
Next
End Sub
End Module
没有错误检查,但它有效。
