I tried with "hr = m_pRecycleBin->CreateViewObject (m_hWnd, IID_IShellFolder2, (VOID**)&pDetails);"
But problem is remain same.
It is also returning E_NOINTERFACE.

What is the "scope" of a mutex? (you know, when preventing multiple instances)
Is it "active" for multiple users?? i mean, lets say an app creates a Mutex to mark it's residency....if a second user executes an app...and it attempts to "OpenMutex()" is it successfull??
Also What's the Scope of Atoms??? (across multiple users)
offtopic : how long does it take for an article to be verfied by CP staff?

I'm no huge expert, but I've just had a look at the documentation for CreateMutex...
Terminal Services: The name can have a "Global\" or "Local\" prefix to explicitly create the object in the global or session name space. The remainder of the name can contain any character except the backslash character (\). For more information, see Kernel Object Name Spaces.
Windows XP: Fast user switching is implemented using Terminal Services sessions. The first user to log on uses session 0, the next user to log on uses session 1, and so on. Kernel object names must follow the guidelines outlined for Terminal Services so that applications can support multiple users.
So, I'd guess you need to put Global\ in front of a mutex name for the same one to be accessed (and there used) by differing processes from differing users.
If you look online for the documentation, I'm sure you can see how they work for Vista too - but I'd be surprised if it's different.
As for atoms? They're all around us, maaaaaaaan. (OK, I don't know, but I imagine it's in MSDN too)
OT: Mine took ~2 weeks, but that wasn't recent.

Hello everyone,
1.
After my study, the address of IAT of an executable is known at compile/link time, other than known at load/runtime, right?
I have this confusion because if an EXE needs to link with an import library, some of the instructions in the import library contains pointers to the address to the IAT entries of the EXE (right?) which needs to be fixed-up during load time. So, if IAT address is not known at compile/link time, import library will not be able to contain pointers to the address of IAT.
2.
IAT address of an EXE is some default address which has the same values for all EXE?
thanks in advance,
George

So, if IAT address is not known at compile/link time, import library Lookup Table will not be able to contain pointers to the address of IAT.
Yes. That is true...but certain programs (like viruses,exe protected files) can "build" (or rather fill) their Import Table by themselves...The IAT is sometimes "purposely" corrupted ...it used to be some kind of anti-disassembly trick. (i doubt if it works anymore...)
IAT address of an EXE is some default address which has the same values for all EXE?
No, It does not have a fixed addr...You can grab the RVA (Relative Virtual Address) from the PE Header...For the Physical Address you'll need to convert RVA into Physical Address.

No. i guess i need to have admin rights to register an OCX.. right?
Thanks.. Guess the query is resolved

At first, you need to be an administrator or power user to register a component with DLLRegisterServer. But don't yet decide your query is resolved. It could have failed for other reasons too.

I'm working in a VC++ project. I've received an error which states that
error C2440: 'static_cast' : cannot convert from 'void (__thiscall CPerspectiveView::* )(UINT,short,CPoint)' to 'BOOL (__thiscall CWnd::* )(UINT,short,CPoint).
When I double click on this error,the cursor goes to a Windows Message Map called ON_WM_MOUSEWHEEL(). I have checked the address of the function corresponding to this Message in both the files(i.e .cpp and .h).
They are the same only. Please help me to resolve this error.
|
|
|
|
|
i assume CPerspectiveView is your custom class derived indirectly from CWnd
the return type of the function corresponding to the message map should be BOOL.
change the return type of message handler for ON_WM_MOUSEWHEEL in the CPerspectiveView to BOOL;
|
|
|
|
|
|
the problem can be with the return type.. change the return value from void to BOOL. is should work.

I will not do that.
If you want to do that, you need to tell us what you've tried and where exactly you're stuck.

Normally to create and run the MFC SDI application, the document page will be displayed.instead of doc user can add our own excel sheel and run the application output should be displayed in excel sheet.
