Just a shot-in-the-dark:
Based on your code line alone:
BYTE *pb = reinterpret_cast<???>(m_pProcess) + m_pProcess->MaxSize();
Is MaxSize by any chance the fourth virtual method in m_pProcess? Do you have a memset(m_pProcess, 0, sizeof(...)) or equivalent somewhere? If so I think you are zeroing out the vtable. You can't use memset on a class with virtual methods.
Based on the code above that is the only thing I can think of that would make it crash.

Thank u very much for attending this matter.Actually I dont know what is error that comes when im runing the application.
There appears a window asking whether to send the error report to Microsoft. I tried to see the technical information in that report.But can't understand.It states about an exception. The appilication error states that the memory could not read at a location(memory address was given)
When I debug it following appeared..

Right - that is to be expected! That information says exactly the same thing as your OP.
> The thread 0x9C8 has exited with code -1073741819 (0xC0000005).
0xC0000005 is the code for an access violation. I refer you to my previous post - what is m_pProcess? One of your classes? Or a library class? If so, which library and what's its type? CProcess? Check to make sure you aren't memset-ing m_pProcess to zero anywhere.

look at the Shell_NotifyIcon() API. You can add an icon, then later modify it using this API.

Hi all,
I have flicked through the examples here on CP but not really found what I want. I'm looking for code examples/thoughts/ideas on the following:
1. Self modifying code
2. Self detecting if exe has been copied
3. PC serial numbers (anything unique to a single computer)
Maybe it is impossible but I am trying to develop 'full version' exe that will revert back to a 'demo version' if copied to another machine.

Not possible as far as I know.

Even if you were to take the HDD's volume/serial number, what would happen if my HDD crashed and I got everything restored to a new HDD? The software would detect that something is different and stop working. I'm not sure how to effectively handle this.

You can do this in Assembly, which is more fun than C++ anyway.
Good luck with it

the only thing i can think of is using resources, reate some kind of CRC em embedd it in a resource (ex: image)
However this is easy to crack

Network card adapter number (MAC address)?
People could allways change the card from one PC to another, but the software only works wher the card is.

Thanks for all the ideas everybody. This project is just something I would like to try in the near future. I guess I have a bit more reading to do before I make a start.

U r looking for objects in a class or objects of a class? If it is the later, ie how to track the the number of objects created for a class, u can use below demo.
class InstanceCntDemo{<br />
<br />
private :<br />
static int nCnt; <br />
public:<br />
InstanceCntDemo(){<br />
nCnt++;<br />
}<br />
static int GetCnt()<br />
{<br />
return nCnt;<br />
}<br />
};<br />
int InstanceCntDemo::nCnt =0;<br />
<br />
int main(){<br />
<br />
InstanceCntDemo ic;<br />
InstanceCntDemo ic1;<br />
InstanceCntDemo ic2;<br />
InstanceCntDemo ic3;<br />
<br />
int nCnt = InstanceCntDemo::GetCnt(); <br />
};
Does this make sense?
Cheers MiltonKB.

Dear all,
I had one MDI application and I want to limit its execution to single instance.
I had tried source code from lots of articles (i.e Newcomer's, Naughter ...Armen...)
it will work ...but while closing the second instance it raises an exception ...
Abnormal program termination!!!
This exception generated from "WinMain" when the
"pthread->ExitInstance()" get called...
How can I solve this ?
I am using Windows XP SP2 .....and VC++ 6.0
Thanks in advance......
