I have one Singleton COM Server which is launched by the windows service. In antother aplication i want the interface pointer of the Singleton COM Server.(Both are in single machine). In this case instead of getting the existing Singleton COM Server pointer its creating a new instace. Whenever we declare a COM Server with DECLARE_CLASSFACTORY_SINGLETON macro. It will create a one instance on the local machine. Any body plz suggest some possible ways to overcome this problem

Hello,
I need the updated WUA header files from M$ for a project.
(http://msdn.microsoft.com/library/en-us/wua_sdk/wua/updating_windows_update_agent_header_files.asp)
Unfortunately are the links on their site broken.
Where can I download the file wua_api_headers_i386.EXE?
And can somebody help me with code snippets for beginning with the WUA api?
Please.
Thanks.

In VS 2003 one may find two different looking web browser controls. One from .NET named the AxWebBrowser1 and the other thru' the interop via COM. What is the purpose of this second one whose object name is WebBrowser? Can this be used together with MSHTML for some application? This one has no visiblity except its availability thru code. I am interested in knowing whether it was included to the C++ developers or does it have any other utility.

Yuwraj,
please note that messages posted in these forums are coming from real persons and not compilers. Hence do not post messages that are kind of the-following-code-contains-errors-please-find-them without any explanation.
Describe the error, what environment you are using and what you are trying to do and then, maybe, someone can provide you with some help.
The more information you give about your problem, the more detailed help you can be given. This is also why your post has not been answered earlier.
Now, about your code...
Both IEngine and ICar have the same UUID in the code snippet you posted.
If this doesn't help you, post some more information about what errors you get when you're building.

It's supposed to be hard, otherwise anybody could do it!

LIBID and CLSIDs are equal too. Not that I think that will mean any problems. The two IIDs will however.

Hello Yuwraj !
When I objserved you code, I found two things :
1. you put same IID for both the interfaces
2. same ID for class and library.
But actully all these are to be different. so, put different IDs for all the elements... 
- Malli...!

Hi
I try to write an Web Application on wich you can draw some
lines using the inkobj.dll.
In ASP.net, no Problem. You have to create an Windows.Forms.Control wich
you can call from an <object> Tag in your ASP.net Webapp.
I just want to know if it's possible to draw some lines using
classic ASP and the COM Object.
Some Code:
<br />
var oInkColl = Server.CreateObject("MSINKAUT.InkCollector");<br />
oInkColl.hWnd =
I think hWnd needs an Form Object.. How can I say that the Window is the IE?
I that possible?

I get this message when I use mshtml in vb.net. I am trying to declare a variable doc as New mshtml.HTMLTextElement
An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in test.exe
Additional information: COM object with CLSID {3050F4BA-98B5-11CF-BB82-00AA00BDCE0B} is either not valid or not registered.
I find the CLSID in Googles' folder in HKEY_USERS with the same qualification, that is:
CLSID {3050F4BA-98B5-11CF-BB82-00AA00BDCE0B} is either not valid or not registered.
Could it be Google's search somehow getting into the registry?
Any clues? hints? suggestions? links?

Hi,
I have two questions :
1) How would you create a singleton ATL COM Class? (Like when you do a CoCreateInstace for the interface, you always get the same instance of the class)
Right now I did a work around of declaring all the data as static variables.
I also read about a macro called as DECLARE_SOMETHING_SINGLETON (Not sure about the correct name)
2) I also have some global functions in the same COM Class. These global functions need to access the COM Class member functions. So the global functions need to access only the single instance of this COM Class at any cost. My COM Component is an Out-Proc Win NT Service.
The global function code looks like
CALLBACK Global_Fn()
{
//call the class's function
CCOMCLASSA *pA = NULL;
pA->MemberFunA(); //this is crap piece of code, but due to static vbles, it is working as of now
}
Any ideas to do all this elegantly? All help will be greatly appreciated.
Thanks
Misha

1. You're thinking of the DECLARE_CLASSFACTORY_SINGLETON macro. You'd use it like this:
class ATL_NO_VTABLE CYourClass :
public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<Csadfas, &CLSID_sadfas>,
public IDispatchImpl<Isadfas, &IID_IBlah, &LIBID_ATLPROJLib>
{
DECLARE_CLASSFACTORY_SINGLETON(CYourClass)
2. Given that the class factories have been registered (it's an .EXE server) using the CoRegisterClassObject API you can safely and efficiently implement your globals like this:
void MyGlobal()
{
CComPtr<IMyInterface> spInt;
if ( SUCCEEDED(spInt.CoCreateInstance(CLSID_YourCLSID)) )
{
spInt->YourMethod();
}
}

I am again into dilemma here. I am sorry, very new to COM programming.
The problem is:
I have two kinds of functions in my COM class.
1) Functions that are exposed via the interface
2) Internal routines of the COM class which the global functions/main program may need to call
So if I am creating a COM Class, does it mean that the only link to my COM Class should be via the interface routines? i.e. all the internal routines which require to be called by the global functions also need to be exposed as interface routines?
So what I gather from this is that if somebody wants to access your COM Class (from anywhere, say the winmain routine of your service or some global function in your COM Class itself etc), it has to be via the interface pointer only.
Any help greatly appreciated.
Thanks & Regards,
Misha

The easiest way (not pretty to look at) is to make your functions look like this:
void MyGlobal()
{
CComPtr<IMyInterface> spInt;
if ( SUCCEEDED(spInt.CoCreateInstance(CLSID_YourCLSID)) )
{
CYourClass* pClass = static_cast<CYourClass*>(spInt.p);
pClass->YourMethod();
}
}

I think it won't work that way. Maybe (and I'm not sure) only if the COM object is created within the same process. In that case you could do like:
CYourClass * pClass = new CYourClass();
instead of creating any com object.

I was assuming that the globals you were talking about where in the COM server - In which case the technique I gave will work. You couldn't just create a new class each time because it wouldn't be a singleton in this case. If the global you're talking about are meant to be in the client then this technique will not work - But in that case the only real solution is to expose the functionality as COM interfaces.

Thanks Stephen,
I was looking all over the internet for an answer to this. And to say it was just a macro DECLARE_CLASSFACTORY_SINGLETON.
