hi all,
i've asked a similar question recently regarding accessing the Windows
Address Book by creating a wrapper class in C#
I need to know whether I'm barking up the wrong the tree?
What i've started doing is creating the required structs and declaring
function calls within the wab32.dll in managed code (C#) but the problem i'm
now faced with having to pass an pointer (IntPtr) to an interface as a
parameter to one of the functions.
Do i have to declare the interfaces i need as c# interfaces? or can i need
to DllImport them?
if you know what i'm talking about then you probably know i don't
any help / pointers appreciated

Sam,
Which function are you trying to declare in wab32.dll? If you can give
the function (and possibly the unmanaged declaration) it would help
tremendously.

hi nick,
thanks for reply,
it's
HRESULT WABOpen(
LPADRBOOK *lppAdrBook,
LPWABOBJECT *lppWABObject,
LPWAB_PARAM lpWABParam,
DWORD Reserved2
);
Basically i'm guessing the implementation would be something like
[DllImport("wab32.dll")]
static public extern uint WABOpen(ref IntPtr lppAdrBook, ref IntPtr
lppWABObject, ref IntPtr lpWABParam, uint Reserved2);
so you can obtain an IntPtr to an object (interface) that has a series of
methods, how do you then invoke those methods?
Thanks
Sam

Sam,
You should actually define the IAddrBook interface in your code (using
the appropriate ComImport and Guid attributes as well), and then set the
return type to that. The COM interop layer will take care of it. Just make
sure that the parameter type is "ref IAddrBook".

ok, so i think i've got it
basically define the IAddrBook interface in c# - how do you know what Com
attribs to use
I've been looking for a while now and still no good examples of how to do
this. (normally the interop classes are created by tlbimp no?)
thanks again mate
