How might that piece of software work? I found it a few hours ago and it apparently it uses NtShutdownSystem(). I've done some research on that, and it doesn't seem to cause any disk corruption.
Any advice? Thanks.

I was going to mention this earlier but decided not to give you bad advice. You are correct in that you can safely call NtShutdownSystem() and it will (probably) not corrupt the Windows OS. Because NtShutdownSystem() flushes the registry hive to disk and empties the page file and then flushes the cache of all drives and disables interrupts before emitting the same machine instructions I posted in the prior posting.
However you need to consider that everything executing in ring-3 will be oblivious to what your doing. Which means any applications with unsaved data will be unexpectedly terminated. This also includes the service controller which expect its ScShutdownNotificationRoutine to be invoked by a CTRL_SHUTDOWN_EVENT message. You may need to manually invoke ScShutdownAllServices() if possible. BTW this is why Windows takes so long to shutdown... each service is given up to 20 seconds to respond to the SERVICE_CONTROL_SHUTDOWN notification. Most respond within a second or two.
I would also recommend broadcasting a WM_QUERYENDSESSION followed shortly by a WM_ENDSESSION message to all top level windows. At least give them a chance to shutdown properly.
But now we are close to Microsofts implementation now aren't we! 
I'm afraid your on your own here. I certainly hope this is not a commercial application your creating. 
Good Luck,

So what difference does it make if your application exits before or after Word or Paint?

If this code actually works... it will only work in DOS. I don't have a DOS box here in my office so I cannot test it.
void RebootWithoutAsm(bool bWarm)
{
int iWarm = true == bWarm ? 0x1234 : 0;
void ((*Reboot)())=(void(*)())((0x0040L << 16) | 0x0072L);
*(int*)((0x0040L << 16) | 0x0072L) = iWarm;
(*Reboot)();
}

Hi, i wonder if there is a method to get more informations about the inside of a template. For example
template<typename databasetype="">
int OKDatabaseFile<databasetype>::OpenDatabase ....
Inside this function OpenDatabase, i have the template DATABASETYPE. I can get the size of this template with "sizeof", still i want more. I want the number of variables inside the DATABASETYPE struct, i want the names of the variables, the datatypes.
Is that possible?

no. C++ doesn't have any such capability.

Does the WS_EX_RTLREADING style work for you? It can be set at design time as well as run-time.

I have 3 USB ports on my PC. I am using one for my keyboard and other is connected to a mouse and the 3rd one is free.
But the device manager of my PC shows 5 USB Universal Host controllers 27C8,27C9,27CA,27CB & 27CC.
I will be connecting a controller board to the free USB port. I need to use CreateFile(), ReadFile() and WriteFile() to read and write to the USB port.
Now how do I identify the free port?
|

You don't access the USB port the same way you access a serial port (so, you don't specify the "port name" to the CreateFile function). Instead you get a handle to a device driver which will communicate with the USB device. So, you need to give the identification of this driver to the CreateFile function. This is of course totally dependant of which USB device you are trying to communicate with. Normally, this should be described in the documentation of the controller board.

a simple cast is not enough, you need a string conversion, for instance using WideCharToMultiByte, see this sample.

Have you tried:
printf("\n equivalent string is [%S]\n ",(char*)pTmpBuf->usri3_name);They don't necessarily hurt anything, but you might also consider removing those unnecessary #include statements.

Hi,
I developed an application in MFC dialog,
where i am printing the Html page using ExecWB command.
The problem is, initially my application memory consumption is low.
But when i call print command (ExecWB) the memory usage rises
tremendously.
But for further execution of command its stable..!!
I am not getting whats the exact problem is..??
Plz help me in this regard..
Thanx in advance.

Maybe it's something internal to the ExecWB() function.

void CWebBrowser2::ExecWB(long cmdID, long cmdexecopt, VARIANT* pvaIn, VARIANT* pvaOut)
{
static BYTE parms[] =
VTS_I4 VTS_I4 VTS_PVARIANT VTS_PVARIANT;
InvokeHelper(0x1f6, DISPATCH_METHOD, VT_EMPTY, NULL, parms,
cmdID, cmdexecopt, pvaIn, pvaOut);
}
Actually its internally calling 'InvokeHelper' which may b using some
stack..

Can you show us what ExecWB() is doing?
