Re: How to add a dual interface to a non-ATL, non-MFC Application

16-Nov-09 2:15

Hello VC++ gurus,
I have to add a dual interface to a non-MFC, non-ATL application.
I have a non-ATL, non-MFC enabled project and a plain Win32 application. Now, this Win32 exe must expose some services through an IDispatch interface.
My question: Can I somehow use ATL to help me with that IDispatch implementation? Event if the project is a non-ATL project?
Note: My Win32 exe must act as Local Server (CLSCTX = CLSCTX_LOCAL_SERVER) here.

I'll appreciate your help a lot.
Regards

P.S.: Thanks to all how replied to this thread.
I'll try to use ATL in my non-ATL project: use CComObjectRootEx, CComCoClass, IDispatchImpl and CAtlModuleT<base> etc. straight away. So far, it looks OK.
Regards,
Joerg

Getting the most out of IDispatch[^] may have the answer you are looking for.

Thanks. Now, let me try to understand the XYZDispatchDriver: does it assume that the IDispatch Interface has been defined (in an IDL) and a coclass has been implemented? Or, is this created dynamically on the fly?
In my situation, I do not yet have IDL defined, class implemented.

Joerg

Sorry, I'm not a COM expert, I just remembered this article from my own studies on the subject. You could try posting your question at the end of the article as it will then go to the author, who probably is an expert.

I've seen that; just trying to be lazy and avoid all that handwriting... Is there a "lazy way"?

Using ATL once you know it is "laziness" (in a good way), but learning it?

You mean, I can add ATL templates, macros and an ATL IDispatch implementation, eveen if my project is not an ATL Project? Would be good enough for me.

I suppose (note: suppose) it would be simpler transforming you project in a ATL one.

Win32 DLL Resource not found Error

There's something wrong in the post: it looks like a direct request to another Italian woman (i.e an e-mail (un)intentionally posted on the forum). The same poster was able to write a request in good English here http://www.codeproject.com/Messages/3272888/Re-Problem.aspx[^].

Hi every one,

I develpoing a MFC application which uses a Win32 dll. This Win32 dll contains a DIALOG Box resource. I wanted to show this dialog by calling an exported function from this dll. But when calling this dialog through
DialogboxParam API it returns with error 1812( RESOURCE NOT FOUND). I am solved this problem in MFC by calling AFX_MANAGE_STATE(AfxGetStaticModuleState( )). How to do this in Win32 way.

thanks

For pure Win32...

The DialogBox function has a first parameter of

hInstance

, which is the HINSTANCE of the DLL where you get the resource from.

If you loaded the DLL using LoadLibrary, then you already have that parameter. If not, then when the DllMain function of the DLL is called at load time, then the HINSTANCE is passed then. Just remember it!
(ie, in a extern variable that all the CPP files in the DLL have access to.

That's how I did it in the old days!

Hi Iain,

I am loading the dll using LoadLibrary from a MFC application. And i am using a global HINSTANCE value from DllMain.But still this cause problem. Is this cause the resource handle of the dll be changed?

thanks

Erm, your first email said you were succeeding with MFC.
I told you how to do things in pure Win32.
Now you say you still have problems.

These facts do not fit each other.

Please expand on what you are doing, so I can help better,

Iain.

Hi,

Try passing AfxGetResourceHandle[^] as the first parameter to the DialogBoxParam Function[^].

Hi:

I have started working with the library VTK and I want to use Windows Forms as GUI. I supposed that I have to create an OpenGL view on a Windows Form, and then connect in some way with VTK classes.

HOW I can do that? I'm trying to represent an VTK object in a Windows Forms. Anyone have any simple example?
I'm new in that and any kind of help would be welcome.

I'm using c++, how can I do that? Whee is this information been saved?
Can I have an access to it?

Thanks a lot
