I have done a control with some stock prop pages. It works fine until I added a font stock prop page. I get a warning from midl saying font type doesn't follow automation. In the test container it works fine to change the font and in design mode in VC too. But when I try to run a client with the control it says "Invoked failed on DISPID xyz..."
What additional coding from the wizard-generated code has to be done to get the font stock prop page to work?
Cheers!

Where is the best place to go read how to use COM+ without the acronym MTS being mentioned?
Kind regards,
Al.
VBer who wants to go back to, but will have to learn again, C++. I'll carry on using VB for the front-end; so when I get proficient at C++/STL can I jump straight to ATL and avoid the MFC?

Hi All:
How I can create such a ActiveX control that can catch all the messages of the container.
For instance, When the frame (contain my control) resizes, My control can be informed and do some things.

Have a look at this and can anyone help me ?
classA.h
class A
{
class B;
method_A;
method_AA;
};
***********************
classB.h
class B
{
Method_B;
Method_BB;
};
How (if one can that is) do I access a method in class A say method_A from the Method_B in class B ?

OK,I found a very simple solution...
template <class t,="" const="" iid*="" piid,="" class="" cdv="CComDynamicUnkArray">
class CAdviSeNotify: public IConnectionPointImpl<t,piid,cdv>
{
public:
typedef IConnectionPointImpl<t,piid,cdv> baseClass;
CAdviSeNotify(){};
virtual ~CAdviSeNotify(){};
STDMETHOD(Advise)(IUnknown* pUnkSink, DWORD* pdwCookie)
{
T* pT = static_cast<t*>(this);
pT->OnClientAdvise(pUnkSink,piid);
return baseClass::Advise(pUnkSink,pdwCookie);
}
STDMETHOD(Unadvise)(DWORD dwCookie)
{
T* pT = static_cast<t*>(this);
return baseClass::Unadvise(dwCookie);
}
};

The New ATL Object menu item was disappeared from my Insert menu. Anyone knows what happened to the ATL Object Wizard and how can I get it back as normal?
Thanks,
Tony
|
|
|
|

Select Tools/Customize, then select "Insert" from the "Category" combobox on the "Commands" tab. Drag the icon for the "New ATL Object" command over the "Insert" menu, and drop it into place.
Thats it!

Hi Folks, Does anyone know how to capture no. of clicks on an Image drawn through an IPicture Interface in an ATL Project. Also is it possible to redirect to a website when a user clicks on the Image.
Thx a lot.

HI,
Say I have a MFC application. On InitInstance or InitDialog I want to check if there is any COM server(registered) that belongs to the application.(I don't know any CLSID)Is it possible to do that. If so then I wan't to add an item in the menu for each com server I find.
|
|
|
|
|
Hi,
Information about registered COM objects is stored in the registry. You can try the CLSIDFromProgID function to check if specified ProgID is registered. You can also create an instance of the object and then release it, to be 100% sure that all pieces in place.

Hi,
COM object is a binary file, and dll also binary file.
what is difference between them (internally)?
thanks,

Hi,
COM object can be stored in the DLL or EXE file. When a COM object is stored in the DLL the only difference with the usual DLL file, is that the COM DLL must have several COM related methods:
DllGetClassObject
DllRegisterServer
DllUnregisterServer
DllCanUnloadNow
See description of these functions in MSDN for more details...

Hello Everybody 
I have written what I think to be a comprehensive, seven-step tutorial which is easy enough for beginners to use, and posted it on The Code Project to help you get started on DCOM programming. It guides you through using and doing:
+ Implementing a DCOM server as a Windows NT Service;
+ using the ATL COM AppWizard;
+ using all of the Visual C++-IDE features like New ATL Object Wizard, Add Method to Interface, etc etc
- implementing Connection Points:
+ Over the network with DCOM
+ On the client side with MFC and ClassWizard (!)
+ MFC and AppWizard and ClassWizard on the client side
Full source code provided for each step of the tutorial, and a full client that reports status is provided with the last step, plus a source code archive and Questions and Answers page.
Check it out! It's as yet an "unedited reader contribution" but I want to invite you to look at it anyway and let me know what you think. Feedback is so very needed on this kind of a project.
The tutorial starts with Step 1. Enjoy!
(NOTE: "Step 1" above is a hyperlink to the tutorial.)

Hi,
what is exact difference between aggragation and containment.
aggregation is 'has a' relationship between classes.
Inheritence is 'is a' relationship. is it correct?
what about containment?
send me msdn links
thanks,

Hi,
In C++ you can use inheritance, which is 'kind-of' relationship, or composition, which is 'has-a' relationship. You also can use the private inheritance, which is just a syntactic variant of composition.
Aggregation and containment are related to the COM. Aggregation is exposing a binary sub-object to the client as is using the QueryInterface. Not all classes are aggregatable and you may want to expose only part of the object's functionality, in this case you can use containment.
The best source of information on this topic is the Don Box's book "Essential COM".

In simple terms aggregration means that the COM Component has an Internal Interface which is doing all your work though you are talking to front interface which redirects your job to its internal interface. As far as containment is correctly interpreted by me refers to the interface by which COM is exposing the rest of the interface contained inside it.
