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.

Thanks in advance.

Hello,
I need to bring up 2 dialog windows and I need to work with then. How can I bring up 2 dialog windows and use them at the same time?.
When I do it now I can olny use the last dialog I show.
I work with MFC. Please help me.
|
|
|
|
|
|
Just create dialogs as modeless dialogs not modal. Here is an example:
CMyDlg1 dlg1;
dlg1.Create(...);
CMyDlg2 dlg2;
dlg2.Create(...);
A. Riazi
|
|
|
|
|
Create?
What should I type in the Create?
dlg1.Create(???);
|
|
|
|
|
dlg1.Create(ID_OF_YOUR_DIALOG);
A. Riazi
|
|
|
|
|
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.
|
|
|
|
|
Define dlg1 and dlg2 as member variables of your main class.
A. Riazi
|
|
|
|
|
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?
|
|
|
|
|
The Create() member function must show you dialog window, if you didn't see anything, you did something wrong.
A. Riazi
|
|
|
|
|
Well I see that It somehow destroj the dialog window,
Is ther anthing I need to do?

Hi,
In one of our applications, we are using a lot VBScripts to get some work done like file transfer, etc., since the requirements for these normally varies and hence is not nice to put into our application itself.
Now, the problem we are facing is that when these scripts are executed by our application using the CSCRIPT interpreter, common anti-virus apps like Norton, disable them or pop-up a question to the user. Is there a way to avoid this??
Thanks,
Krishnan

We wrote the management scripts for our project using python to get around this problem, but I guess that isn't what you wanted to hear, 
From a quick experiment it looks like NAV hooks into the actual COM objects that of WSH (only a guess) - I tried getting smart and renaming the interpreters, but it still brings up the error dialogs. This Microsoft Knowledge Base Article seems to indicate that Microsoft don't even have a consistent approach to working around this problem.

I don't believe a standard CEdit supports multi-selection.

Hi,
I was doing one of the beginning VC++ tutorials, and I added a member variable to a class by right clicking on the class name and choosing Add Member Variable from the context menu. However, I typed in the wrong name for the variable, so I wanted to delete it. There didn't seem to be a way to delete a variable using the Class Wizard, so I navigated to the variable in the header file, and I deleted it.
However, when I tried to add the variable with the correct name (once again right clicking on the class name, and choosing Add Member Variable), a pop up box informed me the variable name could not be added. So, I added it by hand to the header file, as well as a few more variables, but when I went to build the project, I got 18 errors relating to the top of the .cpp file for the class.
Is my only option to delete the whole program and start over?
Below I included parts of the code with some comments:
