That's beyond what winsock can do. Firewalls involve packet capturing.

I should know how to do this but for the life of me I can't find the answer. How do I convert an __int64 value to a string. TCHAR[XXX] or CString doesn't matter.

I'd try using an ostringstream. It's a better alternative than CString::format or ( heaven forbid ) sprintf in any case.
I have an article on CP if you don't know how to use it.

Thanks for the feedback.
CString strTemp;
__int64 iValue = ULONG_MAX + ULONG_MAX;
strTemp.Format("%d", iValue);
This does not produce the correct result. It works for 32 bit numbers, but it does not appear to work for 64 bit numbers. I have not tried the STL solution, though. I will try it next time I get a chance.
I have solved the problem, though.

Just as Chris said, you have a CString str; you can do a str.Format("%d", yourIntData);

Hello.
Could someone please help on how I can tackle this little program using any data structure( a stack, link list or queue).
Having a computer processing one line at at time,whereby each line of input contains an ID#, a starting time,and a sequence of integers representing the duration of each job.If the jobs are in a 1st run 1st come basis.The output of the program should be a list of ID#s, a starting and finishing time for each job, and the average waiting time for each job.
Thanks.

I'd use a std::deque<job>, where job is a struct defined by you containing the relevant info about a job.

Any help ?
I would like to implement in my own program the Reascan disks of the Disk Administrator of Windows NT/2000/XP.
I can't find any entry in the MSDN...
Anyone knows how to do that ?
Thanks

In order to use the Microsoft Web Browser ActiveX control, I need to call AfxEnableControlContainer() in my App::InitInstance. My application requires that I also call CoInitializeEx(NULL, COINIT_MULTITHREADED).
When I comment out the CoInitializeEx() call, the browser displays. If I let it run, the dialog with the ActiveX control won't initialize.
Any guesses as to what the problem is?

If you're using MFC I believe that you are supposed to use AfxOleInit() instead, though it's been a while so I could be wrong.

Ok, but AfxOleInit doesn't let me set the threading model. And I need a multithreaded environment for my callbacks. When I use it, my callbacks stall out. 
Any other ideas?

I have a standard MFC SDI application. I need to generate some simple text reports to be printed, and I thought I could just have few routines spit out HTML into a viewer control.
Can someone recommend a method for doing this? I already have documents and views, so I don't think CHtmlView will do it for me.
Any pointers would be greatly appreciated.

Who knows how to deallocate memory I allocated using something like this: char *x = new char[100000000]; ? I know tha there is a 'delete' command, but it deallocates mem only for the current app and I want to give the memory back to the OS. Any ideas ?

Take a look at the VirtualAlloc routines.

I have made a program to make questions for a boardgame i'm making. I use structures and write them to a file with fwrite so there are often long strings of unused data stored. The strange thing is that when I use the Release version of my program the long strings is just random garbage that happend to be in the memory. But when I use the Debug version the long strings are made up of the same characters (which is very very good when I compress the savefiles). Why is this happening?

the Debug verion of the memory allocators automatically initailize their buffers.
The Release version of memory allocators simply use the memory as it is found.
This is to allow you to find bugs in debug mode, and not slow down your release mode operation. What you may want to do if you are concerned with this is initialize all of the buffers that you use.

the compiler often initializes memory for debug builds. it's not so nice in release builds.

What kind of view?
It could be as simple as calling SetWindowText(hWnd, ""); It could be as involved as destorying all your internal document objects and calling Invalidate(FALSE);
Unless you are using one of the MFC provided control-views (tree view, edit view, list view), you are doing all the drawing yourself in the OnDraw function. If that is the case you will have to do whatever you need to do to blank the screen.
For CEditView, just SetWindowText, for CTreeView I believe it is DeleteAllItems and for CListView I believe it is DeleteAllItems also.
Look in MSDN for more info.

Everytime I try to step into the VC7 source code (MFC/CRT) in the debugger, VC7 demands that I insert a CD (actually, it tells me it can't find the file, and points to a location on the f: drive, which is even more puzzling, since my CD is the D drive..., and I don't have an F:/ drive). Or sometimes it simply breaks into disassembly code, rather than showing me source. As far as I can tell, the MFC and CRT source code is present on my machine. Does anyone know why VC7 can't find it?
TIA -

It's very frustrating. I get the same thing when debugging. VC will come up and say that it can't find a given INL or H file. I'm like "You installed the damn files! How can you not find them?!" Typically, I simply need to point to the correct include folder, but it's stil annoying nonetheless. There's no doubt that VS.NET was rushed to market as it has numerous bugs
