Hi,
A safe control must not perform disk IO or access the memory or registers of a machine directly. As I know DirectX is using direct memory access. But it's up to you to make a final decision...

So you're saying that you wouldn't mark the control as safe if it is using DirectX. But this control needs to access the sound card for data. I guess that using the multimedia functions of the WIN32 API has the same problem than DirectX, which leaves me no chance to make it a safe control.
Thanks so much, Alex!

Hello All,
I have being trying to use the PDF Reader ActiveX control for IE in my own application. It is easy with VB, but with
MFC I get an error message "catastrophic failure" after
the splash screen is displayed signifying the start of the server, and the viewer does not show up. However, if I try
to resize the view window the same error message is displayed.
Any help? please.
Best Regards,
Paul.

Hi,
I am looking for ways to simplify obtaining data across multiple operating systems. The data could be from anywhere from databases to shared memory to flat files.
My first thoughts were to use TCP/IP and create a custom messaging protocol but I have read a little about CORBA and wondered whether anyone had used and whether it was useful?
DCOM obviously cannot be used as it is Microsoft specific unless you use a COM/CORBA bridge.
Cheers
James

Hi,
I think custom TCP/IP protocol is the best solution! You will never achieve the same performance using COBRA or DCOM. And it's not very hard to do...

I would recommend OmniORB (www.omni.org) It is free.
But as another replied you will never achieve the same performance as you can with raw TCP/IP. That said, we are running 5000 requests a second on a PIII/500 using omniORB.

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,

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.

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!
