It's my bug.
I write:
memset(p,0,sizeof(*p));
which overwrite the list member. Too careless.
|
|

|

i have tried with the sample snippet. its working fine for me. check for the error code using GetLastError
std::list<wsabuf*> m_ListBuf;
WSABUF* pWsabuf = new WSABUF;
m_ListBuf.push_back(pWsabuf);

I declare it in a class
class PerIOData : public OVERLAPPED
{
public:
int m_Operation;
SOCKET m_Socket;
WSABUF *m_pBuf;
int m_BufNum;
int m_NextStart; std::list<WSABUF*> m_ListBuf;
};

wow, you write for all
this code has one bug or no
std::list<wsabuf> m_ListBuf;
CAnswer *p=new CAnswer;
memset(p,0,sizeof(*p));
p=this;
p->m_pBuf=new WSABUF;
p->m_pBuf->len=128;
p->m_pBuf->buf=new char[128];
p->m_ListBuf.push_back(p->m_pBuf);

I used a wrong memset.
Thank you.

As said above,
WSABUF* pWsabuf = new WSABUF is necessary.

use like this, in a thread:

p->m_pBuf->len=128;
p->m_pBuf->buf=new char[128];
when data is received through IOCP:
p->m_ListBuf.push_back(p->m_pBuf);

These are the only two things you have inside WSABUF? can you please display the structure of WSABUF ?

I dont think that new -ing that pointer is necessary.
List will keep whatever the value we are passing in the type specified as template argument.
he may be bugging with some other issues

Check whether there is any dependecies with any other DLL using dependency walker. it is available with Visual Studio.

Are all required DLLs present and registered correctly? Are you using any ActiveX controls?

Try creating the exe in release mode..
If that too fail use Dependecny Walker in the other mechine to find the missing dlls

Use Dependency Walker to find out what all dll's does your application depend on. When you take your app to new location you have to have these dependent dll's there too else the application won't work.

I dont know your code also what is it?
sometimes you need to these files
mfc71d.dll msvcp71d.dll msvcr71d.dll
of course this is not always and it maybe depend to your code
