Off course there are opportunities when you need to use COM or DCOM, but the savest way of using them is to avoid the usage  .
|
|
|
|
|
I've only used DCOM between machines and processes. When I did try to use it quite a while ago, I soon gave up on it due to security and permission problems when trying to do anything between machines in a corporate environment and so used MSMQ (Message Queuing) instead - much easier to work with and provides nice decoupling. Setup a named queue, connect at one end to post messages, connect at the other end to receive messages. Makes testing easy too. As others have said there are other ways as well.

I would definitely use a socket for IPC, maybe shared memory in some cases. The most lightweight interprocess communication channel is probably an unnamed pipe but sockets are more flexible not to mention that the loopback interface is decoupled from the network stack so if both endpoints are on your machine then sockets are super-fast. With sockets you have the opportunity to run the processes on different machines anytime without much effort (possible with name pipes too, but thats more hassle and not crossplatform like sockets). In my opinion COM and DCOM are just unnecessary complications to solve your problem.
|
|
|
|
|
I backup the opinions on using sockets. Use them. That knowledge will help in the long run and will be good for other platforms. I wrote some articles on TCP/IP that might be useful. Search for them on this site.
Thanks for your time

You can use COM objects if you make sure they are automation compatible (have the [oleautomation] attribute and use only automation compatible types in their methods). This will assure that all required marshalling code exists - it will be just like DCOM. There might be other ways (like writing your own marshalling code), but this is a way that will work. You can, of course, also use DCOM.
However, it depends very much on the details of your project, is this is the right way. The advantages are, that COM takes care of everything, like marshalling your data correctly (even between 32/64 bit processes). But also you might run into a lot of things that will be not so easy to solve for unexperienced COM programmers.
There are quite some articles here on CP about IPC, might be worth to take a look there.
In case you want to experiment a bit (and I would strongly suggest that before you decide for a certain solution!) I would suggest WTL (check out http://www.codeproject.com/kb/wtl/ [^]. A series of some very good articles is Michael Dunn's WTL for MFC Programmers). Create a project with the option "Create as COM Server" (will appear in the Application wizard). It will give you an exe project with a UI, that also acts as a COM server. Create two such projects in your solution, add some COM objects and start to play around a bit.

Normally the backward compatibility was planed to ensure that if one soft is compiled for an old version of the library, it can continue to work with the new higher version of the library without recompilation or special adaptation.(situation 1)
Is the reverse also true?
Means if the soft is compiled with the new higher version of dll it can continue to work with the old version of the library without recompilation or special adaptation.(situation 2)
My situation is the first one, So I ask if should I have also situation 2 works ?

|
|
Without knowing what library you are talking about, or what your program does, it is impossible to answer this question.
Use the best guess
|
|
|
|
|
In the end, no one of us can see into the future, therefore it is not possible to say that your program will work with another version of the DLL in the future. Just because it is... you know... the future.

I had an application which is using MFC serialization mechanism w.r.t MBCS (both for serialization/ de serialization ). Now I would like to convert my application to read/write Unicode using MFC serialization mechanism.
What would list of changes in this regard. (dos & dont's) Thanks in Advance !!

Apart from the fact that you need to use the WCHAR and PWSTR types to refer to your characters there is no difference.

According to the documentation[^] that is equivalent to ERROR_MOD_NOT_FOUND which means it cannot find the file containing the COM class.

Here is the VoipTestCom_i.c & VoipTestCom.idl code I used to call the object. The object is nammed SimpleClient and the method I call is nammed TestOnRegisterStatusChanged(). I want to use ATL component into my Composite Control(CYHtapiCom) in C++ with ATL. When i test this code on my atl control. I am getting the error: CoCreateInstance failed 0x0000007e. How to add VoipTestCom controls to an ATL composite control programmatically in Visual C++? Thank you.

LRESULT CYHtapiCom::OnInitDialog(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
CAxWindow wnd;
CLSID clsid;

HRESULT hr = CLSIDFromProgID(OLESTR("VoipTestCom.SimpleClient"), &clsid);
hr = CoCreateInstance(clsid, NULL, CLSCTX_ALL, IID_IUnknown, (void**)&pUnkCtrl);
CComQIPtr spPerStm(pUnkCtrl);
spPerStm->InitNew();
wnd.Attach(m_hWnd);
wnd.AttachControl(pUnkCtrl, &pUnkCont);
return TRUE;

You don't really think I can read through all that and come to a sensible conclusion?
Use the best guess

The obvious question is: did you initialise COM?
Steve
|
|
|
|
|
CoInitialize? Where do I add the CoInitialize?
|
|
|
|
|
Somewhere before you use COM.

Hi
VC++ 2008. I have this web browseron my dialog based MFC app which hosts JavaScript functions thatI access from the app using COM stuff. It worked. I then shifted all the COM related code to a worker thread because that's where I'm receiving data, from the socket, to be displayed on the web browser. And that's where things are not working. I've read things about marshalling which needs to be done if COM is to be accessed from or accross threads. But I can't figure out where to start!
spDisp = m_ex->get_Document();
spDisp->QueryInterface(IID_IHTMLDocument2,(void**)&m_spDoc);
m_spDoc->get_Script(&spScript);
This is the code, copied form some example on the web. m_ex is the pointer to the CExplorer1 object (the web browser control). The program crashes on the last line. Can someone please guide me what to do exactly so that it runs in the thread? Thanks.

At a guess I would say that the second line failed, so m_spDoc has not been given a valid pointer. You should check the results of your API calls to see if they succeed or not, as described in this MSDN page[^].
Use the best guess
