Hello guys,
I have an ATL project with a COM object called IJeremy it has a method called SetMsg which takes an IMessage* as an [in] param.
This object fails to compile - it tells me:
error MIDL2025 : syntax error : expecting a type specification near "IMessage"
What is the best way around to get it to work?
I have tried importing CDOSys.Idl from my IDL, however it does not compile because of many errors.
Has anyone done this before?
Thanks for the help,
Jeremy

Have you tried inserting a forward declaration for IMessage?

Yes, I did that, however, I get another error when I do that.
error MIDL2011 : unresolved type declaration : IMessage [ Parameter 'pIMessage' of Procedure 'Submit' ( Interface 'ISubmitMsg2' ) ]
'Submit' is my method
'ISubmitMsg2' is my interface
Thanks,
Jeremy.

Try moving the forward declaration of IMessage into the library block where ISubmitMsg2 is defined.

Why not pass the IUnknown* I/F and requery back for IMessage* I/F?

I assume that IMessage I/F is your own custom interface. You will have to import the interface definition file that provides the marshalling definition for this interface. This is created when compiling the IDL file that contains the IMessage I/F definition. Give it a try.

Jeremy,
Try making your "in" look like this
[in]BSTR param
make sure you change the prototype in header file to reflect this change and update the function on the CPP file also.
let me know if this helps
in your code after you get the message that the container is returning to you, you will need to do something like this:
STDMETHODIMP CJeremy::SetMsg(BSTR param)
{
USES_CONVERSION;
LPSTR lpParam = W2A(param);
::MessageBox(NULL, lpParam, "Title", MB_OK);
return S_OK;
}
or very close to that in order to read the .

How can I catch a fired COM event in an ATL based NT/win2k service?
I have found only examples of clients written in VB or MFC.

Hi, everyone!
Look at the source codes,
--------
/* #define WIN32 */
#ifdef WIN32
#define MORECORE wsbrk
#endif
--------
Such is the comments,
--------
WIN32 (default: undefined)
Define this on MS win (95, nt) platforms to compile in sbrk emulation.
--------
I have two questions,
1. What means WIN32? When the variable "WIN32" becomes
defined? When it is not defined?
2. What means "sbrk" in the comment? What means "wsbrk"?
Btw: the software is written for both Windows and Linux
platforms.
Cheers,
George

You need not crosspost, unless you intend to be flamed in no time ,

Thanks, StephaneRodriguez pal!
What means "flamed"? My English is not
very nice.  But I will accept your advice.
However my boss is asked me to hand in the
project immediately, but I am in trouble as you
see.
Cheers,
George

A couple of people have already argued against you about the crosspost. See for yourself : the lounge.

Oh, I am sorry about that, StephaneRodriguez.
Yesterday, it is a very urgent case, my boss, ...
I promise that case will not happen again.
Cheers,

We are asking you not to post in multiple forums. For example, your size_t question does not belong in the ATL/WTL/STL forum. Posting in more forums will not get you an answer quicker, and it's considered impolite on the net.

Thats a very non-hurtful way of putting it Michael  ["Damn annoying thing to do on the net" would be another way of putting it  ]

Well, I saw no reason to be mean, really. Now if it had been Bill Sergio, that would be another matter.

Hi, everyone!
I have searched the help page for "size_t" but failed
to find the help page and information about "size_t".
Where can I find the help page or information about
"size_t"? Can you paste detailed information about
"size_t".
Thanks.
Cheers,
George

It's just an unsigned int. Nothing more.

If you're in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins. Maybe it'll make everyone think how stupid war is, and while they are thinking, you can throw a real grenade at them.
