Re: Getting Ethernet Card ID

19-Apr-03 11:08

Another question. How can I get the ethernet card number of a computer because I've read somewhere that that number is unique and I would like to explore the possibility of using it at a unique identifier to protect my software. That's why I want to read BIOS info too, because I can get the motherboard number etc. I have seen DiskId32 but that was too confusing and frustratting enough for me I couldn't find any of the macros, data structures, and functions used by the software.

Check this out:

They also show 2 other methods that don't rely on having NetBIOS.

Reading BIOS

Can someone direct me to a website where I can learn how to read BIOS information using API or MFC, or even Win32 Assembly, please?

I'm not totally sure, but I think under WIN32 you would raise an exception when you tried to access BIOS while running under protected mode. Protected mode is what applications all run under. When apps need resources like perhaps what your requesting, a device driver is needed and a task switch is performed (i believe) where for a small period of time the device driver code gets to run in a un-restricted environment (Starting with the 80x386/286??? CPU's could run in several different states, virtual, protected, etc...it's been a while since I glanced at my assembly books Smile | :)

please forgive any technical discrepancies )

Anyways...I recall reading in a book once that bios parameters were accessed using the IO asm instructions IN/OUT and for some reason PORT 78h or something rings a bell...so you might wanna check that out.

I'll dig through my library and try and find the book i have that actually shows you how to read from the bios, however it will only work under DOS.

Thank you Hockey. I just needed a confirmation. I had tried in the past to access hardware directly by using interrupts but I learned the hard way that that is impossible in Windows, while in DOS that's easy. I just wanted to make sure that there are no BIOS data structures provided by MS, because I have seen some source code where they use IOCTL (I think) macros which don't seem to exist anywhere. And they would access the hardware. I really don't know anything about windows devices so for now I guess I will have to postpone my BIOS reading project, until I develop some skills in VxD.

This will only work in windows 9X. Windows NT, 2000 and XP will use device driver .sys

I was just saying that a VXD will only work in windows 9X.

Problem with MAPI

Hi!

I've got trouble when I try to use another Mailing Program than Outlook or Outlook Express (i.e. Incredimail, ...).
I'm using the Win32 API's functions (MAPISendMail, MAPISendDocument).
The message field is not the one I expect, and I can't attach any files. Incredimail adds "--------------Boundary-00=_U8SLQL80000000000000
Content-Type: Text/Plain
Content-Transfer-Encoding: " in the message field before my text.

Does anyone know how to fix these issues, or have another solution to send mails using Visual C++ 6?

Thks in advance!

Use Spy++ to get the handle of the "Go" button. Get the parent of button and use SendMessage(parent_wnd_of_go_button, WM_COMMAND, 0, id_of_Go_button);

I think it would work... hope....

Rather than manipulate IE with simulated keystrokes and such, why not just use IE Automation. You get way more functionality.

From MSDN:

<big>CWinApp::GetPrinterDeviceDefaults 
BOOL GetPrinterDeviceDefaults( PRINTDLG* pPrintDlg );</big>
<br>
Example<br>

void CMyApp::SetLandscapeMode()
{
   PRINTDLG pd;
   pd.lStructSize=(DWORD)sizeof(PRINTDLG);
   BOOL bRet=GetPrinterDeviceDefaults(&pd);
   if(bRet)
   {
      // protect memory handle with ::GlobalLock and ::GlobalUnlock
      DEVMODE FAR *pDevMode=(DEVMODE FAR *)::GlobalLock(m_hDevMode);
      // set orientation to landscape
      pDevMode->dmOrientation=DMORIENT_LANDSCAPE;
      ::GlobalUnlock(m_hDevMode);
   }
}

Give it a try...

Hi Paolo,

Thank you for your tip, I did try but when it comesto :

<br />
pDevMode->dmOrientation=DMORIENT_LANDSCAPE;<br />

a) I had an Error & could not continue! I attach my small project
PrintLandscape.zip & did send to you ... so that you can see the problem!

b) When I ran debugging until this ,I recognized that pDevMode equals
Zero's ... might be I did not initiallize right?

Can you help a bit more?

Many thanks

Hi,

I didn't get your attachment yet, but are you sure to call CWinApp::SelectPrinter after showing the dialog box?
