Strings in VB are differ from VC. Use BSTR instead of CString.

I was wondering if anybody could tell me where to find a ports list for controling the ethernet card. That or some code showing how to change the cards mac address? The ports would be better.

I think you can't change the MAC address of a card. The MAC placed on the card by it's manufacturer.

sure you can change the mac address....search for it on the web and you'll find applications like SMac which you can use to change the mac address for your ethernet card.

If I changed the MAC address of my network card to one that exist in a LAN, what happened? Also, is it possible to change MAC address of DVB cards?

If you change your Mac Address to something that exists, bad things can happen. Exactly what depends on many things. If you never transmit, and you have a switched network nothing will happen. If you have hubs, then you will see all traffic for the other machine as if it went to yours. (better to tell the card to listen for everything if you want to do this though)

If you transmit you mess up the network, and the sys admin will be down your throat. Don't do it.

Nearly all[1] cards support changing the Mac Address from software. DecNet requires this ability. Everyone is afraid that the last person on earth who runs DecNet will buy their card and it won't work. Besides, because everything ethernet has always supported changing the Mac Address, it is easier to leave that in each upgrade than to take it out.

I don't know what a DVB card is, so I can't speak for that particular case.

[1]It is probably safe to just say all. I know of no exceptions and find them unlikely.

Thanks for your comment. Very useful. DVB is a card for receiving data from satellite. Sending data done via a regular modem but receiving data done by DVB. DVB has a MAC address, if received data contains this MAC, then capture this data and deliver it to Windows.

You'll need to create a couple of modeless[^] dialogs.

Just create dialogs as modeless dialogs not modal. Here is an example:

CMyDlg1 dlg1;
dlg1.Create(...);

CMyDlg2 dlg2;
dlg2.Create(...);

A. Riazi

Larsson10-Oct-04 3:17

Create?
What should I type in the Create?

dlg1.Create(???);

Abbas_Riazi10-Oct-04 3:35

10-Oct-04 3:35

dlg1.Create(ID_OF_YOUR_DIALOG);

A. Riazi

Larsson10-Oct-04 3:39

10-Oct-04 3:39

Yes but the dialog will not show it self.
If I try ShowWindow(SW_SHOW); I still not see it,
And if I try dlg1.DoModle(); its the same.

So how can I bring up the dialog window and see it.

Abbas_Riazi10-Oct-04 3:53

10-Oct-04 3:53

Define dlg1 and dlg2 as member variables of your main class.

A. Riazi

Larsson10-Oct-04 6:57

10-Oct-04 6:57

I Have done that byt how can I show the dialog?,
Well I can use DoModal if I do that I get;
you cant use that with a modless dialog so how can I show the dialog?. If I use ShowWindow(SW_SHOW) nothing happends so I need to show the window but how do I do that?

Abbas_Riazi10-Oct-04 10:14

The Create() member function must show you dialog window, if you didn't see anything, you did something wrong.
