How can I distinguish between a hardware CDROM unit and a virtual one? I tried GetDriveType() but it doesn't ditinguish a DaemonTools Virtual unit from a real one.
In VC++ please...

Erm, that's kinda the POINT of things like daemontools. They spend a lot of effort to NOT be distinguishable. As far as the operating system is concerned it is a CDROM drive. Only at the deep driver level does it make a detour to look at a file on the hard disk, rather than a physical cd.

Thanks! It's over my actual possibilities.

Such applications *normally* use a rootkit[^] to show itself to the OS as a Optical disk drive (or whatever it wants to appear to be). So, you'll have to write application that will detect a rootkit and find if it actually is hiding itself to provide a virtual disk drive capability.
There may be some X application that may not be using a rootkit. So, I don't see a "generic" approach to figure out this stuff.
A crude way is to note down the registry entries and folders all such applications create and look out if there's anything of that present in the machine. But if there were multiple drives (including actual optical drives), ...
Yours is an ambitious project, sir.

I have to show the Pointer position on the Windows XP screen without over-write any information on the screen (like the mouse without using any GUI). Is there any way to do that or I have to use interrupt 33h? If in the latter case, how I do that in VC++ codes to call interrupt 33h?
Thanks for any help

Most interrupts are not allowed/possible in Windows.
What exactly is it that you are after? Are you writing a console or a GUI application?

I think I better off with the console because I would like to show the pointer moving around PC monitor
- I do not want to use any interrupt, but when the pointer moving I do not want it erasing any thing on the screen (like the mouse movements). Certailly, I have to provide the coordination to display the pointer ... but I do not know how to do it.
Can you help

The latter does not require the former. For what reason do you have to have a console application?

I'm not sure what you are saying here, but the mouse does not normally erase anything as it moves around on the screen.

Yes, you are right! Sorry my statement were not clear enough, I would like to display the pointer on the monitor (as the mouse) which not erase any thing when it pass over!
To do the above mentioned, even with VC++ console or MFC or any thing within VC6.0, then it will be oK for me!
For now, I do not know how to do that

The simplest way is to create a dialog-based applicaton, call SetCapture(), and then respond to the WM_MOUSEMOVE message. When you are done, be sure and call ReleaseCapture().

Thank for the suggestion, but I am not sure that I can display my pointer as I wish? Let say I would like to display my pointer (not the mouse position) at the top-left sreen then at the bottom-right of the screen (1280 x 800 resolution) ... what can I do?
Thanks in-advanced

Call SetCursorPos().

It works beautifully, however I wonder that: Can I not use the Dialog base? Because I still have the dialog apprearing on the screen, by any chance we don't have to do that?
Anyway, thanks a lot for help

Your best bet is to just try it and see.

Try searching for these:
FindWindow(<string>) (MFC)
CLSID_ActiveDesktop (COM)
CreateDC("DISPLAY",NULL,NULL,NULL) (MFC)
though I'm also not sure what exactly you're looking for (an interrupt for mouse movement?), the first will get you an HWND to whatever window you want ("progman" is the top level window), from which you can get almost any information you need... the second lets you adjust the desktop, and the third is involved in painting the screen, in case you wanted to capture the screen.
If your window has focus, maybe handle the ON_WM_MOUSEMOVE event (MFC)
...
I also remember capturing the mouse coordinates with a simple DJGPP graphics library circa 2000, so there're probably other ways of doing THAT.

As I just mentionned (in other reply) that I do not want to use any interrupt (but I am not sure do I need it or not) to show the pointer moving around the monitor screen without erasing any thing on it (as the mouse movement)
Can we do it. If Yes, then how I do it & is there any sample available
Can you help me

Hello,
I was hoping someone could provide an explanation on how to open a new dialog window and close the old dialog window with a click of a button. I can create a new dialog window using:
SecondDlg myDialog;
myDialog.DoModal();
However, I have two windows on the monitor when all I want is the recently opened window. I've tried EndDialog(IDCANCEL) and DestroyWindow(), but this just seems to close both window when the OK or CANCEL button is selected.
void CVetDent_11Dlg::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
SecondDlg myDialog;
myDialog.DoModal();
EndDialog(IDCANCEL);
Thanks

Why not hide the first dialog (using...errrm...ShowWindow[^]) before the second dialog's DoModal? That way, you'll only have one dialog on the screen at once, so it looks like the first dialog's been destroyed
As you've found, you can't just have DoModal then EndDialog, or vice versa, as a) DoModal blocks, and b) EndDialog terminates the current message handler.

Thanks Stuart,
That seem to do the trick. Solution code:
ShowWindow(SW_HIDE);
SecondDlg myDialog;
myDialog.DoModal();
EndDialog(IDCANCEL);

In the button-click handler of SecondDlg, call EndDialog() with an argument that denotes what button was clicked. Back in the main window, do something like:
SecondDlg myDialog;
int nResult = myDialog.DoModal();
if (nResult == 1)
{
ThirdDlg myDialog;
myDialog.DoModal();
}
else if (nResult == 2)
{
FourthDlg myDialog;
myDialog.DoModal();
}By chance are you trying to implement some sort of "wizard?"

I have a simple ascii text file on a particular path. So
its at www.website.com/temp/notepad.txt
And the file has a few lines of data. Is there a sample
project anywhere that shows me how to access that file and
read it and make changes to it and close it on the server
side? I can download the file, do what I want to do and
reupload it with changes, but Im trying to find a way to be
efficient and just make the changes on the server side.
Is this possible?
Any response any one can give me will be greatly appreciated.
Sincerely,
Danielle Brina

Mmm - not without some help on the server side, I suspect. HTTP's not really targeted at opening a file, updating it and closing it again.
