Umm - which bit is the function table? (Note - it is NOT a virtual function table - that has a specific meaning, which isn't the one you're using).
I see no function or function calls in sub_4594F5 at all.
Which could be why you can't hook any of them.

No, no i mean sub_4594F5() is the function that has virtualtable inside it, so i hooked it with micorsoft detours and inside sub_4594F5()i want to do vtable hooking like that
int dword_4B006C;<br />
dword_4B006C = (unsigned int)testmy_sub_438213 ^ 0xD6C45DD7;
But function sub_438213 wont get hooked and that function is second function from the vtable
|
|
|
|
|
That is because testmy_sub_438213 isn't being called! They are XORing its address with 0xD6C45DD7.
There are no function calls there! So there's no way any hooking can intercept any calls.

This isn't the problem you are asking about, but shouldn't your operator >> and operator << be using the stream passed to it as an argument instead of using cin/cout?
|
|
|
|

if you mean this yet the same error:
friend istream &operator >> (istream &is,const code_ch &C){
is>>C.number>>C.ch;
return is;
}
friend ostream &operator << (ostream &os,const code_ch &C){
os<<C.ch<<" number="<<C.number;
return os;
}
or :
<code><br />
friend istream &operator >> (istream &is,const code_ch &C){<br />
return is>>C.number>>C.ch; <br />
}<br />
<br />
friend ostream &operator << (ostream &os,const code_ch &C){<br />
<br />
return os<<C.ch<<" number="<<C.number;<br />
}<br />

Yes, that is what I was meant. As I said, it wasn't the problem that you were asking about, so it doesn't surprise me that it gives you the same error message. It was still a problem.
I just spotted something.

}
This function changes the code_ch object passed to it. So the parameter can not be const.

ok thanks it solve my first problem but yet:
[sajad@sajad Desktop]$ g++ c++file.cpp
c++file.cpp: In function ‘int main(int, char**)’:
c++file.cpp:66: error: ‘struct std::_List_iterator<code_ch>’ has no member named ‘begin’

oh sorry ,it is a part of huge program so i only copy it and no member is in the list.but when i fix it and add:
for(int i=0;i<10;i++){
code_ch *h=new code_ch;
h->number=i;
h->ch='1';
w.push_front(*h);
}
or :
code_ch H;
H.number=10;
H.ch='k';
w.push_front(H);
yet the same problem.

True, you still have this problem. Why don't you take a closer look at it.

int *a=new int [200];
for(int i=0;i<200;i++)
a[i]=0;
list<code_ch>::iterator l=w.begin();
cout<<"the list is:"<<endl;
copy(l.begin(),l.end(),ostream_iterator<code_ch>(cout," "));

;
And your error message was:

c++file.cpp:66: error: ‘struct std::_List_iterator<code_ch>’ has no member named ‘begin’

That says that your iterator does not have a begin or end member. It is right, iterators don't. What does have a begin and end? What is it that you want to be copying from?
You should be able to get it from here.

if you mean this?
adding this in the main:
for(int i=0;i<10;i++){
code_ch *h=new code_ch;
h->number=i;
h->ch='1';
w.push_front(*h);
}
or :
code_ch H;
H.number=10;
H.ch='k';
w.push_front(H);
yet the same problem.

No, I don't mean that.
Play closer attention to the error message and the line it is referring to. It is telling you what the problem is and where it is. Go over each part of that line and look for a difference between what you intended and what you wrote.

i can not understand:
even for this does not work:
list<int> PL;
PL.push_front(100);
list<int>::iterator p=PL.begin();
copy(p.begin(),p.end(),ostream_iterator<int>(cout," "));
cout<<endl;
while in another where i wrote:
list<code_ch>::iterator p=t.begin();
int i=0;
while(p!=t.end()){
heap[i]=*p;
p++;
i++;
heapsize++;
}
//part of a program
and correctly works.
does list has not such ability to iterate over list elements as i want to do?
|
|
|
|
|
ok i must write:
copy(x.begin(),w.end(),ostr.....)
very simple error and stupidly error !!!
thanks.
|
|
|
|
|
Good. You got it.
Though of course its:
copy(w.begin(),w.end(),ostr.....)

I know it's a little more than a little funny  but I don't know how some process have the user name SYSTEM within the window task manager while they are not a system process. E.g some anti viruses and ...
|
|
|
|
|
SYSTEM is a user in the Windows system that has a different set of privileges than the interactive user.
This name of the user does not mean it only runs system processes.
For example, most of the services that you create are run in the SYSTEM user context.

Hi
I want to use CArchive to seek backward. I did following:
int CmyClass::Serialize(CArchive& ar)
{
...
ar >> bt;
ar >> bt;
...
----->>>> Move ar file pointer backward here.
}
How can I implement this? Or How can I stop CArchive moving forward while I read something from a file?
Thanks,
|
|
|
|
|
CArchive is not a file, it manages a number of internal data to handle the serialization process, that must remain synchronized with the file itself.
Unless you want to mess-up the file content, you shouldn't move any CArchive "file pointer" (note that CArchive does not define such concept) nor you uattempt any seek to the CFile associated with CArchive.
The proper way to do that is, after saving is finished, close the archive,
cleanup the application in-memory data,
open the archive again for reading (you'd better to constrict another one, not use the same) and read the data from it.

What are you expecting lActual to be? What is the current value of the file pointer prior to calling Seek()?
