Well if you're looking into getting rid of it and you have a Win 9x system have you tried "fdisk"? Just thought I would my two cents Smile | :)

How to Send/Recieve Packets in Client/Server environment based on MAC address ONLY?

I have no problem obtaining the MAC address of a client, given the IP of the client.
IP Helper API under Windows 2k allow the retrieval of the MAC address given the
IP address.

The question I'm having is, if the IP of the client is not given, and only its MAC address is known. Can Winsock send a packet to the client based on the client's MAC address? Likewise, can the client listen for this packet?

I am currently looking into NDIS for possible solution, but hopefully there is an easier solution than NDIS.

The only way I am aware of to do MAC to IP would be if you could some how access a routers ARP table...

Probably didn't help any.

Sorry for not clearly specifying my problem.

I need to communicate MAC between client and server.
By this I mean, to send a packet from the client to
the server (or vice versa) using ONLY a MAC address.

It seems to me that since the bottom layer of the OSI model
talks ARP, it is evident that Winsock communicate ARP
at a some stage. As such, further investigation leads
me to NDIS. Which is 2 layers below TCP/IP and UDP.
It is at this level that I am hitting the break wall.

Any solution you can offer at either the Winsock level
or the NDIS level would be great.

Thanks in advance for the help.

icon topic. please help

Hi all!

I use appWizard to make a dialog base program. the default icon for my program will then be the MFC icon. I have a nice (32 X 32) icon file, and want to use it instead. the problem is when I imported this icon into the resource, the size becomes 16 X 16. This make the picture look very ugly. Besides this problem, was another one. What I did to change the icon was I changed the line:
//m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
with this line bellow:
m_hIcon = AfxGetApp()->LoadIcon(IDI_MY_LOGO);

after doing this, my icon was still not visible. I had to delete the MFC icon from the resource to make mine work.

Can someone please tell me how to change icon the proper way and how to load 32X32 icons

Thank you very much
Vu

I tend to use the resource editor and clear out the contents of the IDR_MAINFRAME image and then paste my icon into IDR_MAINFRAME. Saves a lot of hassle,

Try this Code

HICON hIcon;
LPCTSTR lpIconName;
lpIconName = MAKEINTRESOURCE(IDI_MY_LOGO);
hIcon = ::LoadIcon(AfxFindResourceHandle(lpIconName, RT_GROUP_ICON), lpIconName);
GetActiveWindow()->SetIcon(hIcon, TRUE);

Remember:
LoadIcon can only load an icon whose size conforms to the SM_CXICON and SM_CYICON system metric values. Use the LoadImage function to load icons of other sizes.

using CAsyncSocket class without mfc

hi, ok my question is the following:

i have a win32 project in Visual C++ and i'm not using mfc whatsoever. Lets say i created a dialog window from a resource file, so it displays a window on the screen, still pure win32. Now if i go to the classwizard and i click "add new" i can add a new class based on another class. I pick CAsyncSocket as the base class and it adds the class to my win32 project. If i try to compile now i keep getting "Base Class Undefined" and it adds a line to the cpp file of the SocketClass "#include "script1.h" but that file doesn't exist.

Is this because you can't use the CAsyncSocket class without mfc or do i have to change some things to make it work?

Thanks for your time Smile | :)

CAsyncSocket is part of MFC. you'd need to include MFC include files, and link to MFC libs, and enable "use MFC" in your project.

Sorry to dissapoint you all with my lack of a witty or poignant signature.

We make a device which currently connects to the COM ports.
However of late I see COM ports are to be abolished mid-next year.

Does anyone have any info on programming USB???

I see there are hardware converters available to convert COM->USB.
What exactly do these do? Surely software written to address a COM port cannot access a USB in the same manner - so the adaptor is rendered useless???
