Well, it never goes back to NULL in correctly behaving app. CWinApp::~CWinApp just deletes m_pDocManager. But you're sure that at this point m_pDocManager is NULL when your app exits?

Yes,
It's definately null by the time the destructor is called, but the conditional breakpoint isn't called.
Does the advanced breakpoint work if its a memory overwrite ?
Interesting point -- I put a breakpoint in the connstructor and its actually called twice? I thought there was only ever 1 CWinApp derived object.

Yes, there should be exactly one CWinApp-derived object. Look at the call stack when code hits the breakpoint in constructor.

The first CWinApp Derived is
CWinApp _afxOleWinApp;
the second is the normal
CExplorerApp theApp;
I think its safe at this point to mention that i'm using some activeX controls in my applications. I suppose thats what the _afxOleWinApp is all about.
The constructor is called twice becuase two objects are created, but the destructor is called once.
I think i've got it.
The descructor is called for _afxOleWinApp and since no documents have been added to this one the m_pDocManager is NULL by the time the destructor is called.
This must cause some error and the app to terminate incorrectly.
What is _afxOleWinApp is this correct behavior, to have 2 WinApps?

_afxOleWinApp is defined in dll-related MFC source files. The comment next to declaration states that '// This CWinApp is required so this module state has a CWinApp object!'
It seems you're somehow managed to mix dll-mode MFC into your .exe. Is _afxOleWinApp declared in dllinit.cpp or dllole.cpp?

Maybe your ActiveX controls are MFC-based?

I reckon they are.. i'll contact the author.
Should it matter though, I thought the whole COM ActiveX thing was entirely self contained i.e. it shouldn't matter what they are written in as long as they have the same interface.
So basically, CExplorerApp theApp; is not being destroyed. So VC is picking up memory leaks.
There must be an error after the destruction of _afxOleWinApp before theApp can be destroyed.

Got it.
The brute force method. Make a baseline and then change code randomly untill it goes away.
Turns out it was some sort of strange recursicve pointer deletion in the Splitter Window Class.

Hi dear,
I want to save the CDC class content into a bitmap file.
How can I do this?
I've done it by using GDI+ simply because this functionality exists in GDI+ library. But I don't wanna use GDI+ in my application.
|
|
|
|
|
I hope you don't mind me asking but i was looking to implement similar functionality in my app a bit later.
Is there an article or some information you can point me to as to how to accomplish this?
Cheers

Hi dear,
I'm looking for a class or library for crating a 3D plot
for x,y,z series of data, programmatically.

Thank you in advance.

Hello,
I try to figure myself, but can't, so please help:
I want to place a input box and a button in taskbar,
which stay there all the time. When user have to search for a
keyword, type it in input and hit the button.
Which is the way to place windows controls in taskbar?
But in system tray instead??
Thanks in advance.

You need to create either a application bar or a taskbar (band?) which contains your controls.
int x=1, y=5;
x^=y^=x^=y;

Objects in the taskbar are called "Desktop bands". Article here[^]

Thanks a lot, at least I know now what
I'm searching. I really forgoted the
term "Desktop band", and I did lot of searches
after other keywords.

apart from the fact that include statements in .h files will also be included in any other files that include that .h file there is no difference.
I prefer to only add #include statements in .h file if absolutely necessary if it isn't i use forward decraltions of the classes.
