Depends on how sane your USB-Parallel adapter is but it should still be LPT1: unless you also have a genuine parallel port. There will be a horrible, USB style, mile long device name as well but the chances of using that successfully in any software designed to talk to COM1: or LPT1: I would rate at low to very low.
If LPT1: is absent then a session of poking around in Device Manager or SysInfo should give you your answer.
Good Luck.
Nothing is exactly what it seems but everything with seems can be unpicked.

Yes, the machines I'm testing on both have a real LPT1:, and yes, the long USB name (or bits thereof) is unusable. Further spelunking in the SDK doco led me to QueryDosDevice() and DefineDosDevice(). Using these, I can create a LPT2: device, attached to the same \Device\USBPDO-? that the USB alphabet soup is linked to. It works most of the time - I think I have a USB timing issue, since firing up a (software) USB protocol analyser makes it work better. LPT2: doesn't survive a reboot, but I can handle all that in startup code.
Thanks

So here I am teaching myself some of the command line tools for AD when I realize that some of my changes don't seem to be working. In a panic I scour the net, msdn, technet. White papers. Blue paperss. Yellow papers. More.
All that trouble could've been avoided had it been mentioned that from time to time when using the command line AD may not render your changes. Solution. Press F5 to refresh the GUI.
Hope some of you find that as useful as I did.

Can anyone tell me how to run a full screen app on two Screens in xp? App in windowed mode is fixed size, but will accept any resolution for full screen on command line, but the os only puts the full screen app on one screen. in windowed mode it ignores the command line resolution argument. Cheers

AFAIK maximize always uses and fills one screen, being the screen that contains most of the
window when not maximized. There is no way to maximize over more than one screen. (The
excuse may be it is not always true the combined screens form a rectangle).

I thought so too, until I met the Nullsoft Installer (NSIS) User Manual (.chm). On my system with a rectangle of two monitors (secondary above primary), it came up over two full screens. Maximise it and it fills one screen! On my other system with two different-sized monitors it behaves as you describe.
No idea what's going on.
BTW, this monitor stacking makes negative screen coordinates do something useful.
Cheers,
Peter

Hi,
maximize behaves as I stated before.
if you have the source code, you can make your app cover whatever rectangle you want,
including the sum of two screens (if that's a rectangle) by giving it the appropriate
Bounds; but then you are not running in "full screen" mode, and as you noted,
maximizing it would bring it back to one screen.
BTW maximize mode sets the window size a bit larger (IIRC 4 pixels) than the screen size!

In a multithreaded server unix environment, when the system calls are invoked
it is returning the descriptor number 0 randomly and is creating decriptor leakage problems.
Noramlly the system reserve 0 ,1,2 for input ,output and error.

Hi,
It is said that using the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Policies\System\DisableTaskMgr
we can disable Task Manager for all users of a computer. As I test it, in both Win2k and WinXp, its not true. The registry key is only effective if used with HKEY_CURENT_USER, not with HKEY_LOCAL_MACHINE.
Can anybody help me with that, plz?

Thanks, But I have to disable Task Manager from a C++ program. So I can't use the Group Policy Editor (gpedit.msc) of Windows to do this task.
I need to do this via HKEY_LOCAL_MACHINE of the Windows Registry.

Why do you wish to disable this tool with a dll?

I want to provide an interface for the user to enable/disable all windows access options(My computer, partition access, network setting, log off...). The Disable Task Manager is mentioned only as a sample. I had managed this in a previous version of my program.
The real problem started when I decided to run the program(for security issues) from 'RunAs' option of Windows. So whatever used to work for HKEY_CURRENT_USER does not work anymore. I need to find a way to enable/disable windows access option for ALL users of a PC within the program(I can't use Group Policy Editor). I tried to use HKEY_LOCAL_MACHINE but it does not work at all, despite being mentioned in may websites like http://www.pctools.com/guides/registry/detail/163
That's the story.
I'd be grateful if anybody could help me.

If you're building a GUI you may find a better answer asking this question in the forum dedicated to your programming language of choice than a more general forum such as this one.
Otoh, you could always build a batch file then use the button click event of your GUI to envoke the batch file....hmmm
