Thanks for your reply, but this is not for my demand.

I''d searched on Google and I found some snippet, but I couldn't understand precise sequence.

I want to capture images from full screen Direct3D applications(e.g Games) by my program.
How to do this ?

I can retrieve multi-monitor informations by API, but MONITORINFOEX::szDevice is not the commercial name of the monitor that directed by MONITORINFOEX.

How can I retrieve the above informations ?

I've fixed this problem !
Seems this error had not came from CComQIPtr and COM。　MFC's some points might be causes... fmmmm

I'd resolved by using OnWindowPosChanged event handler on CChildFrame.

I using CPaneDialog-derived class(called CMyPane) and MDI-tabbed document style on MFC.
CMyPane will be docked to CChildFrame using DockPane method of CChildFrame.

CMyPane will be docked...

I've saw no difference by this method.

I have to unregister my COM component for the special reason that related to the running state of my application( running or shutting down. e.g. DirectShow filters). So I handling the registration of...

No, it's a special case. I'll use COM smart pointers mainly. it's just a test case.
I found the problem in implementations in basic MDI-frameworks( CMainframe, CChildFrame, CMyApp, CMyDoc, CMyView)....

There are users who think like that some software are not uninstalled after uninstallation if some COM components don't unregistered. So I do these things in my program.

And sorry for my poor...

I mean the nullification as the uninstallation of software modules.
I've known about the nullification of pointers of COM interfaces in terms of 'SafeRelease'.

By the way, therefor I've deleted...

Yes, the problem is in my code exactly, but access violation exception message pumped up in the ntdll.dll.

Thanks Arjay
But if I didn't run this code at least once this issue will occurs.



CoInitialize(NULL);
{
ISkype *pSkype(NULL);

// do something

I've created COM smart pointers only in the main thread explicitly and above worker thread just using the skype's COM interface.


void operator()(void)
{...

skype4COM is a COM library.
I didn't use LoadLibrary so I didn't use delayed load.

I've using '#import' pragma to import Skype's class information like below in the cpp file that implementing...

My worker thread routine is as below.



class Worker{
Worker(){}
void operator()(void)
{
CoInitialize(NULL);

The above code is just the initializing part. CoUninitialize is used in my program.

I've known the delay load of DLL but have not known the delay load around COM and CComPtr(or CComQIPtr). What is that ?
I haven't using delay loaded DLL(s).

Additionally, I've using Skype4COM.dll...

Ｔｈａｎｋｓ.
I'm using many CComQIPtr(s) and released all of them before CoUninitialize and checked timing of release, therefor I couldn't resolve this issue. Why?

Do you mean the 'smart pointer' as COM's smart pointers ?
How is the boost::shared_ptr ?

But, I hadn't saw this problem on VS2008.

I've screwed up with an access violation in the _delayLoadHelper2 function when I closing the application.

My application using COM and CoUninitialize function seems a cause of this problem.
What...

My program using COM and some DLLs and this program invokes access violation exception when I close the application. I've grabbing information below


- dli {cb=36 pidd=0x5caf5a1c ppfn=0x5cb175e4...

I've solved this problem by enumerating documents from document templates and proceed desired behavior.
It's a safe way to synchronize between each view.



GCDEF, thank you for this log...
