You don't need to convert. You need to use secured version advised by the compiler.
Refer Security Enhancement in CRT[^] for more information.

I am working on a project where i have to generate a lot of image files. While i am doing this, the size of the page file increases such that i run out of memory. I am thinking of flushing page file at certain intervals but not sure if its the right idea. I am not even sure if it is possible to do it programatically. Is there anyway to programatically flush the page file??
Regards,
Srinivas

I dont think its good idea i dont even think it would be posible. page file will be automaticly flushed when you will delete your in memory images. if you still have images in memory loaded and flush page file you will be in trouble bro because when you will access image it would try to load from pagefile and there you wont find anything.

Whats the result if you run this code?
CMenu* m_MainMenu= GetMenu();
CMenu* m_Submenu = m_MainMenu->GetSubMenu(0);
m_Submenu->EnableMenuItem(ID_TEST, MF_BYCOMMAND | MF_DISABLED );

In my code, I have instantiated a template class in the following manner:
CallbackWrapperSpecific<MainWindow, void (MainWindow::*)(int&), int>* cbwsPtr = new CallbackWrapperSpecific<MainWindow, void (MainWindow::*)(int&), int>(this, &MainWindow::DoWork, i);
The above object is a functor, which encapsulates a class member function pointer. In this case, I assume that the class member function pointer always has a pointer to this (meaning that the class does not go out of scope while the functor exists), but I would not like to make the assumption that the functor pointer will not go out of scope, because it may very well do so until the time that the function pointer actually gets called. If it goes out of scope before that, then I will lose the pointer to that object and run into a memory leak. The difficulty here is not in capturing that pointer and deleting it later, but rather, in capturing that pointer, and making sure to delete it as a class of the type that I have listed above. Manually recasting to such a long-winded (and infinitely varying) type is not a good solution.
Because new and delete check the sizes of the objects (I think), would it be a good idea in this case to call malloc(), store both the pointer and the size of the pointer initially, and then call free() on the pointer, while specifying a size?

you definately do need help.
Please read the guidelines for posting questions (at the top of the forum), then maybe modify your post to reflect those guidelines.
Then maybe you might get a better response

I think you can find a cube on the examples of MSDN did you see it?

I would like to intercept outgoing port 80 connections, redirect the http request, and inject the response back into the stream as if it had never been redirected.
Each time a user desires a web page, he transmits a request to a web server, and the web server transmits a response back to the user. Let us assume that user A is only able to access the IP address of user B, but user B is able to access the IP addresses of everybody. If user A desires a web page from someone other than user B, he will be unable to. The solution is as follows.
When user A requests a web page, instead of sending the request directly to the web server, the request is sent to user B. User B then requests the same request from the web server, and receives the corresponding response. That response is then sent back to user A.
To user A, it appears as if the request and response were completed with out having to send packets to user B. This is because all of the tunneling work goes on in the background. User A does not need to configure his web browser to connect to a certain proxy. Instead, when user A requests a certain page from a web server, a program running on user A's computer intercepts that request, does the necessary tunneling to user B, and finally injects the response back into user A's tcp stack, as if user A had himself contacted the web server.
I do not want to use a normal proxy. This all needs to occur in the background. The problem is implementing the previous paragraph. How do I tap into the windows tcp stack like that? I know that Google Desktop does it to modify search results, so it is definitely possible.
How do I do this? Sample code anyone? Sample projects? Any articles that have been written on this? Any help is welcomed.

Given the following two classes:
class A
{
public:
A() {}
A( const A &si )
{
m_strName = si.m_strName;
m_strStatus = si.m_strStatus;
}
A( const A *si )
{
m_strName = si->m_strName;
m_strStatus = si->m_strStatus;
}
A( LPCTSTR lpszName, LPCTSTR lpszStatus )
: m_strName(lpszName), m_strStatus(lpszStatus)
{
}
virtual ~A() {}
private:
CString m_strName;
CString m_strStatus;
};
typedef CArray<A*, A*> arr;
class B
{
public:
B() {}
B( const B &mi )
{
m_arrServices.Append(mi.m_arrServices);
}
virtual ~B() {}
arr GetServices( void ) const
{
return m_arrServices;
}
private:
arr m_arrServices;
};I can't seem to figure out exactly what the compiler is complaining about (other than the obvious). I've changed the typedef statement to store actual objects, and references to an A object, all to no avail. I've had different types of constructors for A, but none of them seem to make a difference. The B::GetServices() method is supposed to return a copy of the m_arrServices array. I don't want to return a reference or a pointer to that array because I don't want it changed.
Both classes have several private members that I'm trying to provide getter and setter methods for. Any ideas?
Thanks,
DC

My first thought as well. I suspect the 'problem' for the compiler is with the CArray class. It must be attempting to call some form of copy constructor which doesn't exist. I'd investigate the implementation of CArray with a view to determining which one.
Of course it is just possbile that the definition of CArray doesn't exist at this point in the compilation, if it was forward declared, and the compiler can't determine whether there is a copy constructor or not. It's cautious like that 
Nothing is exactly what it seems but everything with seems can be unpicked.

CArray doesn't have a copy ctor. It doesn't matter what you use as the template params, there's no copy ctor to copy any CArray object. I'd suggest this:
const arr& GetServices() const { return m_arrServices; }Or if you absolutely can't return m_arrServices (the caller could cast away the const and muck with it) make the caller pass in a CArray that you fill in:
void GetServices(arr& a) const { a.Copy(m_arrServices); }

I think the copy constructor on CArray is declared as explict and therefore its not allowed to create a copy.
Sameer.

In an SDI application i am using one dialog box and i am using many number of radio buttons. When i close this dialog box and open it once again is there any way that i can get the same dialog box i.e which buttons which i selected earlier(before closing the dialog box).
Please reply.

Yes, just save the state of the buttons in a configuration file or the registry.

If you are closing the dailog and open it again without closing the main SDI application then u just have to make the dialog class object a member variable or a gloabal variable ( not recomended ). Now I suppose u r doing it as a local variable.

If u really dont want to close the dialog, just hide it instead of closing.
