When I'm debugging a DLL that uses DirectShow, and I make a call to OleCreatePropertyFrame, the program produces an access violation (0x00000005) and all i get is a window with this:
00000000 ???
00000001 ???
00000002 ???
00000003 ???
00000004 ???
00000005 ???
00000006 ???
...
...
FFFFFFFF ???
One of the lines is highlighted, but it also reads "???".
What the heck have I done to get this? How do I find out what's really wrong?

Seems like execution has jumped to the low area of virtual memory. Maybe some callback that has not been properly set?

Maybe, try to delete a object twice, or use the object had been deleted

Guys, Any body remember how I can get the cpu in C, Not in VC++... I'm sorry for this very old Question....

Hola Carlos,
I've found this (seemingly abandoned) Intel's white paper: Intel Processor Identification and the CPUID Instruction. It comes with some asm and C code you can copy and paste.
I'm saying "seemingly abandoned" because it's in the Intel's Russian site (!) but nowhere on developer.intel.com, and the files it refers to are not downloadable anymore (though you can copy & paste from the paper, as I said above).

If your computer says, "Printer out of Paper," this problem cannot be resolved by continuously clicking the "OK" button.

Forget about "seemingly abandoned". Here's the latest version of the doc (at developer.intel.com).

If you're using MFC, then you could use CObArray. Or one of it's derived classes ( CStringArray, CPtrArray, CByteArray, CWordArray, CDWordArray).
They're pretty funky and already do exactly what you want.
Sorry to dissapoint you all with my lack of a witty or poignant signature.

I have an ActiveX control which fires an event. In the event handling code in the containing app, I create and display a pop-up menu. If I click anywhere outside of the menu, it gets dismissed as expected, but the application stays stuck in the menu modal loop until I get the menu to display again by again firing the event from the control (by clicking the control again).
Whats going on?
And more importantly, do you have any idea on how to fix it?

This is just guessing, but could it be that you haven't specified correctly the parent window in TrackPopupMenu?

Thanks for the tip, but the correct window is the parent.

Another guess: maybe your event handler is being called from a different thread than your main window belongs. A possible fix could be that the event handler sends a user message to the main window (say WM_HANDLE_EVENT) and then doing the popup menu stuff in OnHandleEvent (which executes in the right thread). Maybe it's worth a try.

I need to export C++ objects out of a DLL. The objects don't have to be used outside of the DLL, they just have to be able to be passed back in to the DLL for use inside - essentially, they are containers for the DLL's state.
These objects would never be shared between threads or processes.
I was thinking this might be a way to do it:
typedef HGLOBAL HMYOBJ;
HMYOBJ GetDLLObject()
{
HGLOBAL hObj = GlobalAlloc(GPTR, sizeof(CMyClass));
CMyClass *pClass = (CMyClass *)hObj;
pClass->Init();
return (HMYOBJ)hObj;
}
...
BOOL UseDLLObject(HMYOBJ hObj)
{
CMyClass *pClass = (CMyClass *)hObj;
return pClass->DoSomething();
}
void DestroyDLLObject(HMYOBJ hObj)
{
CMyClass *pClass = (CMyClass *)hObj;
pClass->CleanUp();
GlobalFree(hObj);
}
...
HMYOBJ hObj = GetDLLObject();
BOOL ok = UseDLLObject(hObj);
DestroyDLLObject(hObj);
Does that seem reasonable? It does seem to work, I just wanted someone else to look at it.

Does that seem reasonable?
It looks very reasonable to me except for one thing. IMHO instead of
HGLOBAL hObj = GlobalAlloc(GPTR, sizeof(CMyClass));
CMyClass *pClass = (CMyClass *)hObj;
pClass->Init();
return (HMYOBJ)hObj;
it's simpler to write
CMyClass *pClass = new CMyClass();
return (HMYOBJ)pClass;
which works just the same.
If you want to take extra precautions to make sure that the object passed back from the user app is a valid pointer, you can have an internal table of pointers and pass an index to that table, instead of the actual pointer --that's how Win32 does it most of the time.

Dear all,
Would you please help me with subj. I want to send defenite packet by means of Winsock2, and destination is MAC address not IP address. But I haven't found how I can do that by using WS2. Is it possible to resolve this prolem?
And if it possible to do in this way, could you ask to me, how I can create packet with required to me structure.
Thanx in advance

I don't think you can do that.
The IP network that you are transmitting traffic, uses the IP address to route the traffic. If there's no IP address, it won't know where to go.

Yeah I gave inaccurate information. I would like to send packet on the mannear of ARP protocol, which would turn on computer in my internal network (192.168....). Simply to say i want to use Wake-up on LAN function. Is it possible to do with VC++ tools and in particularly with using WSock 2?
Thanx for your time

In Platform builder (3.0), I created a CEPC based WinCE OS which I want to download on a Laptop (Toshiba Tecra 8000) by using the parallel port since the laptop does not have the required CE-Debug compatible ethernet card. the "loadcepc.exe" programs always fails with:
"
Sending boot packet: aa
WaitForStatus: PPSH Disconnected
"
I am able to start a release build of the WinCE OS (Kernel debugging disabled) after I copied the nk.bin file over to the target.
However a debug build always resets the machine.
Is there something wrong (not standard) with the parallel port of the Laptop?
Hints and tips receive a warm welcome.
BR,
Gert.

never mind, I just figured out I need a special parallel cable, which my collegue manufactured while burning his fingers with the solder...

Hi,
I´m running and Ms Word instance in-place, but if I fail to create it ( for example when there is one instance of Ms Word running but unstable), it shows an ugly exception message from word ( then If the user presses ok, my program will continue and it will create the embedded solution), that message is shown in:
pItem->CreateNewItem(clsid);
Is there anyway to avoid that the message is shown to the user ?
Thanks, Bye !

I would like to create a sort of library of method in vc++ to be used in excel. So i believe that if i create a .dll application instead of a .exe, i would be better. But i have read that i could use especially OLE Automation for that kind of application. I have read in msdn the comexcel sample, but it's not really what i want to do.
In fact, i would like that the methods defined in first in vc++ could be used in excel as we could to simply when we create functions in vba. So how we could do that? Where could i find samples?
thanks in advance for your answers.
