C++ and collections

[Jake]

Hello

I am interfacing a C++ program with a VB program and I am trying to
determine how to properly define the collection in my c++ program. I
am using the import function to import the functions of the dll that I
am interfacing with and when I look at the tli file that is created
during the compile I see the following
inline _IMSUsersPtr _cIMSBch::GetIMSUsers ( VARIANT_BOOL UserGroups )
{
struct _IMSUsers * _result = 0;
HRESULT _hr = raw_GetIMSUsers(UserGroups, &_result);
if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));
return _IMSUsersPtr(_result, false);

_cIMSBchPtr ptrIMSBch(__uuidof(cIMSBch));

ptrIMSBch->GetIMSUsers(FALSE);
I do above statement and it compiles but at this point it does not
have a problem because I don't have a datatype setup to return the
collection into

What I want is something like the following

usercollection = ptrIMSBch->GetIMSUsers(FALSE);

but I don't know how to define usercollection - From what I can tell
the return value definition is a

struct _IMSUsers * <---Does this mean that C++ sees the collection
as a ptr to a structure?

I have tried different things but have not come up with a solution

one of which was

_IMSUsersPtr ptrIMSUsersPtr(__uuidof(IMSUsers));

ptrIMSUsersPtr = ptrIMSBch->GetIMSUsers(FALSE);

This compiles but goes off into lala land when it runs

struct usercollection *collectuser

collectuser = ptrIMSBch->GetIMSUsers(FALSE); - does not compile

(ptrIMSUsersPtr)collectuser = ptrIMSBch->GetIMSUsers(FALSE); - does
not compile

Can someone help? I am a little confussed.

Ultimately we are going to have a function that returns a couple non
related data types as well as a collection. However the collection
will never be used in my interface but the dll I am interfacing with
requires the collection as something that needs to be returned because
other future interfaces might require the use of the collection. This
seems strange for me to ask to define something that is not used
directly but nonetheless it happens to be the case so given that I
need to do make sure that the collection is defined properly so that
it compiles and that can hold the returned data.

Any ideas?

Thanks
Jake

I think you might rather try asking in a VB forum, as it appears that the
information you require is highly VB-specific; this newsgroup deals only
with C++ *language* issues.

Good luck,

When you're struggling with basic C syntax you should not be attempting
to interface C++ with other languages.

No doubt you'll get it to "work" and it will be full of bugs.

Forget it.

I'm not sure why you wasted your time posting if you didn't have any
real insight into the issue. Maybe your just trying to feel superior
for whatever reason (tiny penis) but really all I wanted was some
help. After all that is the reason these groups exist. Your attempt
to insult me while I am trying to ask for help only makes you come off
like a jerk.

Please don't quote signatures, don't post off-topic questions, don't
post infantile dribble to the group, and in general, read the FAQ before
posting. You got good advice in spite of that. Now please disappear.

Now, now children. To the OP: yes, you committed multiple heinous crimes
against Usenet etiquette (see above).

To Alf P.: that was to my mind unnecessarily snippy. In particular:

Perhaps you have never been in the situation where your job *forces* you
to engage with some technology that you are unfamiliar with. Not good,
but perhaps the OP has no option.

No doubt you'll get it to "work" and it will be full of bugs.

Maybe, but that's unhelpful.

Forget it.

Tell that to his boss.

The return value seems to be a class and not a raw pointer. That might be
the reason why your attempts did not work.

Since we can hardly guess what you are doing without actual source code and
class declarations, it would really be better if you ask this in a
Microsoft or VB specific newsgroup, as the other posters suggested.

Lets have a go at parsing your post.

to plonk - put someone in one's killfile.
mom - Americanism for mother
ass - either a wild donkey or the Americanism for arse.

So we have

"Put your mother donkey/arse in my kill file"
