First find some virus, study how they function, and how they infect the system, Then figure out how to reverse its action, And there you have an antivirus.

Wow - that's a tall order. I would suggest that you actually need to actually design and write one, and then ask for help on more specific issues.
But for starters, I would guess you need to find out how to:
* Hook the filesystem (so you know when files are being changed)
* Storage and update mechanisms for virus signatures
* Heuristics to detect new viruses
* Efficiently scan the changes to see if they match known virus signatures
* Isolate infected files and/or revert the changes being made (for isolation, you probably want a storage environment where files cannot be directly accessed or executed, like an encrypted virtual file system?)
* Internally validate your code to ensures it isn't infected by malicious code or otherwise affected by somethign trying to undermine it (man-in-the-middle attacks, shutting down components, outright replacing them, etc)
That's a big job, so I wish you good luck.

OK look at one I wrote and see if this would help you.
If so I can post the source.

Please remember I just check for one virus at a time at this point.
To do it properly you are going to have to do some array work.
Also may have a leak or two.
Wrote it in one night for a buddy the got WelchWorm.
Used a great deal of code off this site.

When I call UpdateData(TRUE) on my non-modal dialog, a box pops up saying that this action is not supported.
Is UpdataData() strictly for modal dialogs?
I have several textfields linked to some UINT variables.
using: [VISUAL STUDIO 6.0 sp5] [WIN98/2]

|
|
|
|
UpdateData works on modeless dialogs (and property pages). You probably have removed a control associated to a variable...

There you go :
strFileName can be of any file type. The right exe will be launched according to the extension.
<br />
HINSTANCE nResult = ::ShellExecute(NULL,_T("open"),strFileName,NULL,NULL, SW_SHOW );<br />
if ( (int) nResult < 32 )<br />
{<br />
AfxMessageBox(_T("Cannot open file");<br />
}<br />

perfect thank you so much

I am tring to create a groupbox on the client window
in a wtl project. I can not get it to work, it creates
a window the right size but does not paint the text
or the group outline. I have created buttons and checkboxes
and all work fine painting and all.
Here is the code for the groupbox I am tring to create.
hWndGroup = ::CreateWindow(WC_STATIC, _T("Check Item(s) to Disable."),
WS_CHILD | WS_VISIBLE | BS_GROUPBOX | BS_LEFTTEXT | BS_TEXT,
70, 50, 200, 130, m_hWnd, (HMENU)ID_GROUPBOX,
((LPCREATESTRUCT)lParam)->hInstance, NULL);
Thank You

Try WC_BUTTON for the window class.

Hi,
I would like to change the proxy settings of IE for dial-up connection. In INTERNET_PER_CONN_OPTION_LIST structure how do I specify the type of connection ? If I specify the connection type as NULL it modifies the global settings. But, I would like to change for dial-up.
-Thanks

I have no idea if this will help! I just did a quick seach of MSDN (for "dial up) and found "Dialing Up the Internet with RAS".

The following snippet does what you want, I guess:
char szConnection[]=...;
char szProxy[]=...;
INTERNET_PER_CONN_OPTION_LIST List;
INTERNET_PER_CONN_OPTION Option[1];
unsigned long nSize = sizeof(INTERNET_PER_CONN_OPTION_LIST);
Option[0].dwOption = INTERNET_PER_CONN_PROXY_SERVER;
Option[0].Value.pszValue = (LPSTR)szProxy;
List.dwSize = sizeof(INTERNET_PER_CONN_OPTION_LIST);
List.pszConnection = (LPSTR)szConnection;
List.dwOptionCount = 1;
List.dwOptionError = 0;
List.pOptions = Option;
InternetSetOption(NULL, INTERNET_OPTION_PER_CONNECTION_OPTION, &List, nSize); The proxy is set for all protocols within the connection (HTTP, FTP, etc.) Hope this helps.

I need to understand Net Bios Names please.
A static NetBIOS name mapping consists of a NetBIOS name from 1 - 15 characters, a name type from 0 - 255, and a corresponding IP address. TAS resolves a NetBIOS name by first searching the list of static NetBIOS names and, failing that, broadcasting a query for the desired name. Augment name resolution to effectively cross routers by using the Enterprise Name Service or Windows Internet Naming Service.

Good information now may I ask a few question please.
In the following URL
http://www.microsoft.com/windows2000/en/server/help/default.asp?url=/windows2000/en/server/help/sag_TCPIP_und_nr_NetBIOS.htm
I found in part the following>
Gateway Server Service
Computers running Windows 2000 are B-node by default and become H-node when they are configured with a WINS server. Windows 2000 can also use a local database file called Lmhosts to resolve remote NetBIOS names. The Lmhosts file is stored in the systemroot\System32\Drivers\Etc folder. For more information, see TCP/IP database files
I am running XP Home and have found the following information.
Under windows/system32/drivers/etc
file name type
host file
host.ics ics file
imhost.sam sam
networks file
quotes file
services file
protocols file
I am not using wins server so I might assume I am running in B-Mode.
How does one know which mode one is running in?
How does one retrieve the type of protocol any computer might be running?
How do I retrieve the netbios name for any computer.
Once this is done may I get the MAC address by polling with the netbios name?
Best Wishes,
