Hello,
"COM+ Programming: A Practical Guide Using Visual C++ and ATL" by Pradeep Tapadiya is the best.

Ok, I plead guilty for using global variables in a COM project of mine.
I know global variables are bad but sometimes it's hard to avoid.
My question is: Can I have some "global in the instance scope only" kind of variables? That is, inside the instance the variables are global, every class can see them. But each instance of the object has its own set of individual "global" variables.
Is it possible to work around this?

To me this sounds like a contradiction in terms: if “each instance of the object has its own set of individual "global" variables” then they're not global!?!?

Do you write global to mean public?

No. I mean a global variable which doesn't belong to any class. (Quite similar to a static variable. ) Like the "theApp" variable in those wizard-generated MFC project.
Lets say I have an ActiveX control called MyCtrl.
Now I insert two of MyCtrl in an dialog:
CMyCtrl1 m_ctrl1;
CMyCtrl2 m_ctrl2;
And somewhere in MyCtrl there is a global variable int g_nVariable.
The global(or static) variable g_nVariable is shared by m_ctrl1 and m_ctrl2. There is only one copy of g_nVariable.
All I want is a global variable, but of which each instance og the control has its own copy.
If I can get a pointer to the "active instance of COleControl", I can solve the problem too.
Sorry for my lousy English as it's not my first language and I am too frustrated...

Why don't you use just a class member static variable?

Again I ask the question: if each instance has its own copy how is it global since, by definiton, all instances share the same globals?

If the object is not having GlobalMultiUse instancing automatically the object will have its own copy of global variables. No doubts in this regard.

How to set the instancing property in MFC activeX? Thanks.

Hai all.
I have created a Toolbar for Internet Explorer.
I need to get the window handle of an Explorer Band(Created by me) in my tool bar.
I know the class ID of the Explorer Band, and I am able to hide and unhide the Explorer Band using that Class ID , from the toolbar using ShowBrowserBar(&vtBandGUID, &vtShow, 0); function.
But for my purpose, I need to get the window handle of the Explorer Band
How I can Get the window handle?? .
Please Help me
Thanks

IWebBrowser2::get_HWND gives you handle to main explorer window.
Use EnumChildProc,enumerates children using this handle. You should get any window you want.

Hi,
I am working on an application that will require the creation of hot-spots on a windows form (win32). This is the scenario: I want to display a schematic diagram (like a circuit diagram) and high-light certain components as clickable hotspots. Clicking these components will result in events being generated which I can handle.
Please does anyone have ideas about how I can get about this?

How can I access to unread messages in the Inbox folder using C++ (COM/EMAPI).
<br />
void __stdcall CAddin::OnNewMail()<br />

Hi all,
I was using COM. But when I started to use EMAPI I got a link error:
error LNK2001: unresolved external symbol _IID_IMAPIProp in
<br />
IUnknown *pUnk;<br />
spMailItem->get_MAPIOBJECT(&pUnk);<br />
CComQIPtr < IMAPIProp, &IID_IMAPIProp > pMAPIProp(pUnk);<br />
In the link tab I have mapi32.lib.
So where can be a problem?
