Is it possible you've deleted your pointer elsewhere? If so, NULL your pointer every time you delete it, so you can find this bug more easily.

Or the function that created the pointer did it badly, and returned a pointer to a stack variable. If so, it might work for a while, until the memory got re-used...

The 0x4ea5608 looks like a legitimate pointer value - so it was probably correct, even if only briefly.

Hi,

The data located at your m_pBackButton pointer address is the magic number 0xFEEEFEEE which is used by the MSVC debug heap and this would imply that your m_pBackButton has been deleted.

0x80040111 ClassFactory cannot supply requested class

Hello,

I am getting this error :
0x80040111 ClassFactory cannot supply requested class

I already done regsvr32 for the C++ ATL dll file.
When I check the registry, I can find the entry at HKEY_CLASSES_ROOT\CLSID.
InProcServer32 has the dll path as the default while threading model is Apartment.
I verified that there are entries in regedit for :
- clsid
- typelib
- event
- interface.

I called the CoInitialize as below :

HRESULT hr_init = ::CoInitialize(NULL);  // returns S_OK
if (FAILED(hr_init))
{
    return E_FAIL;
}

HRESULT hr_init2 = m_spIEventFiringObject.CreateInstance(__uuidof(EventFiringObject_OD));  // Fails here
if (FAILED(hr_init2))
{
    return E_FAIL;
}

m_pIEventFiringObjectEventHandler = new IEventFiringObjectEventHandler(*this, m_spIEventFiringObject, &CManualTest::OnEventFiringObjectInvoke);

When I run debug, CWinApp::InitInstance() was successful.
It fails at _AtlModule.DllGetClassObject(rclsid, riid, ppv);

When I run the client software, it fails with ClassFactory cannot supply requested class error.
Your guidance on solving this problem is very much appreciated.

Thanks,
Goutam

How is m_spIEventFiringObject declared?
Did you do #import to instantiate the COM component?

Thank you for trying to help.

This is the declaration :
IEventFiringObject_ODPtr m_spIEventFiringObject;

This is from the tlh file (which shows declaration of IEventFiringObject_ODPtr) :
_COM_SMARTPTR_TYPEDEF(IEventFiringObject_OD, __uuidof(IEventFiringObject_OD));

The StdAfx.h contains :
#import "D:\Project\ODepth\ODepth\Debug\ODepth.dll"
using namespace ODepthLib;

I am using below project as sample/template file :
Understanding COM Event Handling[^]

I just made some changes to make sure my program does not clash with the sample file.
The sample file works fine, while my program errs.

MSDN is a bitch to use.

1. use google to search MSDN, prefix your searches with "site:msdn.microsoft.com".
for example, type this in google "site:msdn.microsoft.com CWnd" ...

2. if the links do not work inside the "offline" MSDN, goto 1.

Watched code never compiles.

I also prefer google search for MSDN. If searching at MSDN site directly, the results generally are not in the order of importance that I expect. It could be my misconception.

I Also avoid Bing in MSDN, and Use Google... Sorry Bing. OMG | :OMG:

Results are closer to what i'm looking for, however I user a search such as: MSDN C# System.Core...etc..

this will give a little more info (IMO) because it will give you context, and a dash of outside perspective (Lower on the gage).. and I usually iterate between MSDN and Web until I hone in on what Exactly I'm looking for on msdn.. I've found that the MSFT blogger5s usually have better info on their blogs then the Documentation and the links to the documentation are often in the blog.. a Great example of this is if you try to figure out how/when to use a spin lock....I spend 4 hours on Sunday until I found a random comment on some MSFT blog that actually explained the intricacies of it.

If your interested I think it is an great example of how the documentation is worthless...(actually says that you shouldn't use it really ever).. whereas one blog says it will cause a serious performance hit, and the final one an article about memory management says that it is faster before a threshold....

I'd blame it on the Brain farts.. But let's be honest, it really is more like a Methane factory between my ears some days then it is anything else...

Good experience to share. I remember several years ago, Microsft had an invitational meeting for developers in New York to collect feedbcks to improve the search for MSDN documentation.
That was before BING time. Then the BING took over. As a result, whatever BING does is what we get. No particular search improvement on MSDN could be seen.

Just go to the MSDN Home Page[^] and use the search facility. However, you will find that many search items will return multiple 'hits' so you sometimes need to review more than one link before finding the correct one. For example when searching for CheckMenuItem I got this page[^], but since I know I'm searching for a Windows function I can fairly easily trust that the first hit is the correct one. Try the same thing with a .NET function and its a little more difficult. The only way to get really comfortable with it is to use it as much as possible and you will soon grow to love(???) it.

Don't forget to customize it to your own requirements in terms of country and view type.

Just don't. No good can come of it. All you'll get from MSDN is an impeneterable generic entry, nonfunctional "example" code and a restatement of the parameters that you already got from intellisense.
Do yourself a favor, search with google and open the first NON-MSDN link returned. The only thing I ever got from MSDN was hypertesion and a nervous tick.

I Agree with everyone else. Ever since they revamped the layout earlier this year, the easiest way to find something on MSDN is to use Google (and then probably use a non-MSDN link).

Well despite all the negative comments and Bob1000's suggestion that I was being sarcastic, I'm sorry to say that I find MSDN extremely easy to use. It usually finds the function I'm looking for on the first search, and the answer is generally within the first three hits. Only when searching for something really obscure is Google a better choice.

I use the same configuration on a Dell laptop and it works fine. It is likely that something in your code is not correct. Can you show an extract of the code where the dialog should be displayed?
