In debug mode you can see the memory leaks only if you have created your application using the wizard and MFC.
Not everybody uses MFC and/or the built-in wizards.
What you have to do is either something like:
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
Which is done automatically in MFC and WIZARDS.
Or you could overide the new/delete (and their array versions) and provide your own memory leak checks.

But everybody who has to ask such a basic question definitly should.
Please get me right:
I am not attacking the question on memory leak detection, but the implication in the answer that beginners should not be using the Wizard. We can discuss about MFC, but the Wizard is definitely a good thing to get your Project going: Setting up the whole mess is very error prone.

Use something like Boundschecker.
Or write a wrapper that reference counts memory allocation and memory freeing.

I want to write a Internet Logger that logs all visited websites during a dail up session. I have 2 questions:
1. How do i know the URLs of the websites being visited
2. How do I hide my program from the ctrl+alt+del list?
(I am allowed to show an icon in the system tray, but i have to prevent the user from terminationg the app- I already know how to prevent the user from exiting the application in the normal way- but what if he/she uses ctrl+alt+del?)
Thank u.
Satya Kiran.

You could always takes screenshots at regular intervals, pass them back to your spy server, and then use ocr to capture the urls lol

A browser helper object would do that for you. Or you could install a proxy server.

Hi guys,
I found a useful .Net Training School and thought of sharing it with all of you.They have lots of different courses in Visual C#,Visual C++.Net
Its worth taking a look. It looks like its a new institute in the Bay area.
website address is www.uicsa.com.
Thanks

Hi guys,
I'm sure there are some java gurus out there who also know c++. Anyone know the answer to the following:
In C++, I declare functions such as:
void PassInAConstantReference(const Object& o);
void PassInAModifiableReference(Object& o);
void PassInACopy(Object o);
In java, so far I only see:
void PassInAModifiableReference(Object o);
Any equivalent of the above C++ functions in Java? 
Cheers,
swine

In Java there are no pointers, and no const, and I believe everything is passed by reference.

So you can only do it non-const and by reference? That sux...

Yes, yes it does. I've been whining about the lack of const in C# for months, and the common response is that Java is the same, that's why I know. I've never coded in Java, so someone may correct me, but I'm pretty sure, and I'm *very* sure that it sucks.

Bunch of criminals, Java does have const, namely final!
LPCTSTR Dutch = TEXT("Double Dutch ");
|
|
|
|

so then, would the following work:
public boolean receiveAndUnmarshallInvoke(CRmiInvokeMessage InvokeMessage,
ServerSocket ListenSocket, Socket TheClientSocket)
{
boolean success = false;
if(TheSocket == null)
{
System.err.println("Null TheSocket passed in CRmiCommunicator.receiveAndUnmarshallInvoke().");
}
else
{
TheClientSocket = ListenSocket.accept();
}
return success;
}
Err, as in, the caller passes in a local client socket object for the TheClientSocket parameter, and when the function returns, the caller's local object is now the accepted client socket?
Thanks,

I'm sorry, I could not say, but it should not be hard to design a test to see.

No. In Java, primitive types (ints, floats) are passed by value, anything else (objects whose type begin with a capital letter, if you want a mnemonic) is passed as if with a hidden pointer. In your particular case, picturing a '*' at appropriate places will help you realize TheClientSocket won't hold the newly accepted socket on return:
public boolean receiveAndUnmarshallInvoke(CRmiInvokeMessage * InvokeMessage,
ServerSocket * ListenSocket, Socket * TheClientSocket)
{
boolean success = false;
if(TheSocket == null)
{
System.err.println("Null TheSocket passed in CRmiCommunicator.receiveAndUnmarshallInvoke().");
}
else
{
TheClientSocket = ListenSocket.accept();
}
return success;
}

Thanks Joaquin. So in the code I posted, when the function returns, the new socket object created by ListenSocket.accept() will be deleted once the TheClientSocket local reference (?) variable goes out of scope, correct?
I guess then the only way to implement this would be to go "return TheClientSocket" instead of the boolean, and pass it back to the caller in that manner?

No, it'll be deleted when the garbage collector decides to sweep it off. Whether the socket itself, as a system resource, gets released, depends on the Finalize method of Socket (I think).
I guess then the only way to implement this would be to go "return TheClientSocket" instead of the boolean, and pass it back to the caller in that manner?
This is a way. Another is to have a wrapper class around Socket and pass this to the function:
class SocketWrapper
{
SocketWrapper(Socket socket_)
{
socket=socket_;
}
public Socket socket;
}
...
public boolean receiveAndUnmarshallInvoke(CRmiInvokeMessage InvokeMessage,
ServerSocket ListenSocket, SocketWrapper TheClientSocket)
{
boolean success = false;
if(TheSocket == null)
{
System.err.println("Null TheSocket passed in CRmiCommunicator.receiveAndUnmarshallInvoke().");
}
else
{
TheClientSocket.socket = ListenSocket.accept();
}
return success;
}
...
Socket clientSocket;
receiveAndUnmarshallInvoke(...,new SocketWrapper(clientSocket));

Lol that is really really weird. Are you sure it works that way? So I have to make a whole separate class just to pass a pointer back?
Also.... do I have to explicitly call Finalize() on Socket objects? I thought perhaps it all "just gets taken care of" with the garbage collector... No?
Much thanks,
