Most DOS commands have a Win32 API equivalent (e.g., CopyFile()). Use that instead.

What about using Direct CopyFile api!

Hi
Program crashing before create:
m_pListenSock = new CSock();
m_pListenSock->Create(200); // Before this statment ( Eror is access violation)
CSock() is a class inherited form CSocket class
Regards.

You don't provide any relevant information. Use the debugger to locate the problem more precisely. You can also use the call stack to see what causes the problem.
Where does it crash ? In the contructor of CSock or when calling the Create method ?

It crashes while calling create method

What is the value of m_pListenSock ?
Where exactly does it crash (use the debugger to find the exact instruction). If it's really on the call of Create, then it means that m_pListenSock is invalid.
Alos, what is the exact error message you get. Man, you have to provide more information when asking for help. And learn to use the tools like a debugger, it is much more helpfull than a forum.

Would it be because If the Port creation is blocked by administrator on the system?
If it is becuase of admin rights , then how can i create the port ?

Please provide more information ! And USE your debugger instead of trying to guess what the problem is. The only way to be sure of the problem is by debugging your code. If you know how to use it, your debugger will give you much more information that anybody here can give you.

error is Cx0000005 Access violation

Put a break point before this lines:
m_pListenSock = new CSock();<br />
m_pListenSock->Create(200);
And then press F11 (or F10) to step the program and find why comes the error.
Probally it depends on a bad initialization in the constructor (CSock()), or in some strange operation in Create that uses an unitialized pointer.

CSock * m_ListenSock;
m_pListenSock is the memeber of CSock class that is inherited from CSocket class.
nothing is done in CSock() constructor.
then steps are CServerHandler class that is inherited from CWinThread class
m_pListenSock = new CSock();
upto this step all is fine
it crashes at
m_pListenSock->Create(200);
and says access violation
Regards.

So step into the Create() method to narrow down the problem.

violation is at
if (m_pHashTable == NULL) in the following code in some VC++ file
void* CMapPtrToPtr::GetValueAt(void* key) const
// find value (or return NULL -- NULL values not different as a result)
{
if (m_pHashTable == NULL)
return NULL;
UINT nHash = HashKey(key) % m_nHashTableSize;
// see if it exists
CAssoc* pAssoc;
for (pAssoc = m_pHashTable[nHash]; pAssoc != NULL; pAssoc = pAssoc->pNext)
{
if (pAssoc->key == key)
return pAssoc->value;
}
return NULL;
}
Regards.

have you check, that m_pListenSock hold requested memory or not!

Use CBitmapButton
Set the property of the button as OwnerDraw.
And use LoadBitmap to load the bitmap of the button
Knock out 't' from can't,
You can if you think you can

You can derived cbutton and use event WM_DRAWITEM of course change ownerdraw in property from button

As you can see,any .exe file was compiled by Turbo C (for dos version) will run in dos mode!And if you write an application(in Turbo C) to draw something(a line,a circle...),you'll see these line or circle in dos mode!
