I don't know how to detect electricity failure . But you can write the system status after some time span continuesly. When system shuts down you have nearest system status in ur file.

As Nimbu has said, QueryEndSession is the only way .. that too when the system is not being shut down abruptly. But if you still want to do, do one thing, write the staus in a remote computer.(i.e a Client machine), which gets data(status) from the server(the electrically-downed machine), now atleast you can write, *when* the system actually went down.
like...
<br />
09:40:43-29/6/05 - Status X<br />
09:41:23-29/6/05 - Status Y<br />
(Now the server is down abrubtly)<br />
09:42:23-29/6/05 - Server Down, [Here the client will still be alive to say that he's down]<br />
will this work for you?

If you have a UPS (Uniterruptible Power Supply) they send a message to the PC whe nthe mains goes off so you have time to shot down properly while the batteries in the UPS last.

Excellent Elaine, I didn't think of this idea. This would be the best option for him. But he must ensure that his UPS is enabled with communication port. Here in India, I find only APC providing that feature. That too not for the lower ends. I checked a model on the internet that had USB port, and I bought it home immediately. When I unpacked it, I found no *holes* around  I got disappointed. I called the customer care, they said, it's available only with the Japanese model  .

If we can detect the electricity failure, then we do not need of a UPS 
it is only requires if we need continue our work to power failure time

We cannot. Because at the time that we are able to notice a power failure, it has already happened. And as soon as the hard-disk looses power, it shuts itself down.
Yes, theoretically, the failure is not "sudden", but happens over a (very short) time-span.
If you wanted to monitor for electrical failure, your computer could not do anything else, because he would have to check Vcore every 1000 cycles or so. And even that probably would not be fast enough to trigger a HDD-Write before the disk spins down.
This ONLY works with an UPS, which will notify Windows that "you are on battery now. save everything you can.". All UPSes allow some kind of status monitoring, but you might have to install propietary drivers for older or more sophisticated models.
What I was going to say originally:
"You should really try to claim damages toward your local power company for not notifying you (in written form) two days in advance of any unplanned power failure."
But I thought that was too harsh.
Cheers,
Sebastian

Please find the attached snippet of the code. In the following code I am trying to call a function written in VB using function pointer in VC++ dll. This code works fine if I use the function pointer in main thread. If I try to call the function in child thread then "Unhandled exeption occurs" Can anyone help me out......
Snippet from Win32 dll
// TempDLL.cpp : Defines the entry point for the DLL application.
//
#include "stdafx.h"
#include "MALLOC.H"
#include "STDLIB.H"
long extNumberProc;
HANDLE hThread;
DWORD dwThreadId;
struct strctValue
{
DWORD dw;
};
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
return TRUE;
}
void WINAPI CallVBFunctionForNumber (char* lSomeValueToSend, DWORD s4)
{
typedef long (__stdcall *OutsideFunction)(char*); //Defining the prototype of the function.
OutsideFunction FunctionCall; //Creating an instance that will be used to call the function.
FunctionCall = (OutsideFunction)s4; //Assigning the address to be used for the call.
long da = FunctionCall("Lalit Kumar"); //Calling the function with the parameter.
}
DWORD WINAPI StartScanning(LPVOID lParam)
{
strctValue* s2;
s2 = (strctValue*)lParam;
CallVBFunctionForNumber("Lalit Kumar", s2->dw);
return 1;
}
void WINAPI getpointer(long x)
{
strctValue s1;
s1.dw = x;
BYTE* bptr = (BYTE*)malloc(sizeof(s1));
memcpy(bptr, &s1, sizeof(s1));
hThread = CreateThread(
NULL, // default security attributes
0, // use default stack size
StartScanning, // thread function
bptr, // argument to thread function
0, // use default creation flags
&dwThreadId); // returns the thread identifier
}
The Snippet from VB code is as follows:
Public Sub Callbackfuntion(ByVal str1 As String)
MsgBox "Callbackfuntion"
End Sub
Thanks in advance.............

Where i can find wrapper class so i give a art sense on my application?
|
|
|
|

your question doesn't really make sense.
if you look for wrappers as wrappers, MFC is full of them.
now, if you mean you'd like to wrap your code so that anybody could reuse it, make it a DLL or a COM component...
