If you want a list of running processes, use EnumProcesses from the Process Status APIs. That works on Windows 2000 and later, and on Windows NT 4.0 if you install the redistributable version of psapi.dll.
You can also use the ToolHelp APIs on Windows 9x and on Windows 2000 and newer. Call CreateToolhelp32Snapshot with the TH32CS_SNAPPROCESS flag, then call Process32First to start enumerating processes, and call Process32Next until it returns FALSE to get subsequent results.

Thaks, but that isn´t what I need.
I need process list by using NtQuerySystemInformation Handles.

Stating the same thing twice isn't going to change the way people suggest you do something unless you tell us why you can't use the approved and recommended way? It's always better to use the MS blessed functions than those that are listed as "may be unsupported in future versions" unless there is a good reason. An example of a good reason would be that this is a native mode app. More info please.
To answer the actual question, even though I strongly suggest you get your list the way Mike suggested ...
Looking at the documentation for NtQuerySystemInformation, it appears straightforward to get the list. Call it twice with SystemProcessInformation as the first parameter. The first time, use a buffer for return data (param 2 and 3) that is only a byte long. This will make the sysetm return the required buffer size in the 4th parameter. Allocate a buffer of the specified time. Call it the second time with that buffer to get the actual data.

Startup task items - Norton Internet Security 2007, Webroot Spy Sweeper, Lexmark Printer Controler, Speed Fan, Retrowhatever for WD external HD, Norton Save and Restore.
It usually takes a couple of minutes to get a fully started up Windows logged in, any ideas what I could do?
The computer is a media center, 2.8 GHz, 1 GB of RAM.

Yeah, dump all the Norton junk. My Dad has all that crap installed and sees the same problem.

Well I never got an answer to what I should use to replace it when I asked last time about Norton specifically. All the answers seemed uninformed and not possible for my situation.

I never knew you asked. The big one as far as a performance killer is Save and Restore. It's also useless because my Dad's machine has been killed more than a few times by an installation that S&R just couldn't recover from. It's useless, offering no better performance over XP's built in System Restore.
As far as the firewall, to each his own. I don't use any on my machines.

AVG Anti-Virus is a good, simple, and non-resource-hogging anti-virus package. I don't bother with an outbound firewall, in my experience they're all annoying and offer little security benefit as long as you're keeping malware off your machine. I just use XP SP2's built-in firewall.

My SO got a new laptop from her company that has 4Gb of RAM. I was wondering how useful this is on a 32 bit processor that only addresses 4Gb of physical memory. As I recall from my VAX/VMS days, User space is the lower 2Gb and the upper space is System, for virtual memory, paging, etc. So if the machine has 4Gb of RAM, it means that the entire O/S is running in memory, right?
I don't quite understand what the benefits might be, since the whole idea of virtual memory is to use a limited amount of physical memory for User mode processes. Can someone explain this to me? There's still paging going on, as processes are switch in and out of context, right?

Hi all,
I've recently started a new job and one of my first tasks is to sort out the company login 'script'. It's actually a VB app (with one function spanning 5000 lines...) that displays a form and then configures machine settings, adds reg keys, printers, virus updates etc etc. As it stands, log in time for a machine is ~90 seconds and I've been challenged with not only reducing this to ~20 seconds but to have a look at other ways of configuring the machine at startup.
What sort of techniques are other people using to update their networked machines? I've already started having a look at BITS from MS for installing software updates which looks like it might be a nice solution but that only accounts for about 15s of loading time. Standard desktop OS is XP Pro SP2 if that helps.
Any advice is much appreciated!
Dave

Group Policy and Active Directory is what normally handles this. Get the Windows Server 2003 Resource Kit and read up on it.

I once had a problem like this and it was caused by my firewall(Norton internet security 2007) blocking internet explorer from connecting to the internet.
So check to see whether it is a firewall blocking your browser from connecting.

I've wasted the entire day so far trying to get XP to install and boot off of a new 300Gb Maxtor drive. I've chosen the default partition size of the entire drive, installed XP SP2, and XP hangs on the initial post-installation boot.
I tried formatting the drive with the Maxtor utility with the same results. Then I tried installing Win2K, which worked, but only allowed me access to a 137Mb partition, which is a known behavior.
I'm about to haul this drive back to Fry's to trade in for a different manufacturer, but I thought it might be a good idea to ask the gurus here if this is a known issue.
Thanks,
-- Dave

I had a similar problem once, it was because my BIOS didn't recognize large drives and therefor installed Windows on a 150Mb partition instead of the full 300. What I had to do was update my BIOS and then reinstall once more. The BIOS then recognized the entire drive and installed properly.

Thanks for the information M/C. I checked the motherboard (EliteGroup 848P-A) manufacturer's web site and none of their suppport links work. This board is only two years old, so I'm surprised that a) the BIOS don't support big drives, and b) the manufacturer doesn't seem to be supporting this board anymore. It looks like it's time for a new motherboard  Or maybe it's time to build a new computer.
Thanks again for your suggestion.

Well, my solution was pretty simple. It was clearly the BIOS, so I bought a new mo-bo that was on sale with an Intel 2.6Ghz duo-core processor. $640 later for 2Gb of DDR2, a 500Gb HD for the same price as the 300, a new case, and a super deal on a $20 DVD writer (after rebate) and I've got a brand new screaming system. After the shopping spree, it only took a couple of hours of (very cautious) assembly. The old system has now replaced my ancient Win98 home-use computer, which is now sitting in the recycling pile. I'm a very  dude and the new system is very

IN windows Xp there is a command Runas /user <appln> .The password can be entered only when asked.
Is there any way to give the password also with the Runas command?

Nope. How secure would it be if you could type your password in clear text on the command line?

No Dave - iam not giving it directly from command prompt. Iam calling the command in a VBS file thro my VC++ program.
IT works
Option explicit
dim oShell
set oShell= Wscript.CreateObject("WScript.Shell")
oShell.Run "runas /user:administrator ""PrintArt.exe"""
WScript.Sleep 100
'Replace the string yourpassword~ below with
'the password used on your system. Include tilde
oShell.Sendkeys "yourpassword~"
Wscript.Quit

How much do you want to bet you're not?
This has some problems because you're waiting 100 (0.1) seconds, then sending the keys. What if the window takes longer than that to show up?? You just typed your password into another window, possibly Notepad??  Nice...you just typed your password, in clear text, into a TextBox.

Why???? Why not just do the same thing in your VC++ app where you'll have much greater control?
