I believe you have a little mix-up in your terminology 
There can be up to four "primary partitions" on a disk, where "primary" simply indicated the "most basic partitioning system". Extended partitions are primary partitions, too.
There can only be one ACTIVE primary partition, though.
See here for more information.[^]

Well your right for your explanation but let me add that the primary partition is the one that we can wright on their bootsector(located at the first sector from the first track(512KB) of your PRIMARY partition only which is also called BOOT partiton ) that is, operating systems may be installed on one till 4 primary partitons that gives you a chance for multi-boot(Windows, Linux, BSD Unix ..etc.) on same machine, and extended partitons cannot be boot partitions and thus they may hold logical drives for saving data only!
I really do not agree with you that

Hi,
IIRC Windows knows of only one primary partition on a disk; all other partitions are
either invisible, ignored, or treated as "logical" partitions.
But some tools (I use PowerQuest PartitionMagic) are indicating there can be more
than one primary partition. My disk in a Dell laptop has 4 primary partitions,
1 being Dell-specific (I think it is either a recovery thing or the hibernate feature),
1 is the normal C: partition
1 is an "extended partition" that, at the Windows level, holds all the extra drive letters
(such as E:, F:, G:, ...)
1 is holding some spare room.
And IIRC I once had a desktop PC with Norton Commander, supporting multiple "primary
partitions" and a boot selection (again, once booted, the running Windows OS would
only see one of those, i.e. its own C .
Hope this helps

You can use disk management from (Run:compmgmt.msc) you may use Partition magic or a sort like this...

Hi,
Is there a simple API to detect Windows XP restart within a process?
I wanted to do special initialization within the process startup only right after system restart.
Thank you & Regards, Renuka

try SystemEvents.SessionEnding event

Thank you for the replies. Unfortunately my application is a console application. From MSDN help on the above event it seemed "Console applications do not raise the SessionEnding event".

Hi,
the simple solution is to turn your app into a Windows application then.
the main form could be hidden, or if some input/output is necessary a console could
be simulated on the form.
the same MSDN page however also hints at another approach: shutdown/restart will
result in a WM_QUERYENDSESSION message; so if you manage to set up a message pump
you can still catch these.
I have not done this, nor do I know any details. If I really needed this, I would
try with a separate thread, probably using Application.Run, and a hidden form, and
possibly an overridden WndProc.
I trust going for the Windows app is the easier way !

Hi,
Thank you for the reply. But by design I chose the process to be a console exe.
Thanks again & Best Regards, Renuka

Probably your best bet is to define a special command-line option and put this in your Startup shortcut or Run registry key. Otherwise some way of measuring the system uptime is probably necessary.
GetTickCount is supposed to return the number of milliseconds since the system started, but I believe there are options somewhere to force the initial count to be a large number, so that counter rollover happens fairly soon after system startup, so this may not be reliable. If using the .NET Framework, the equivalent is System.Environment.TickCount.
GetSystemTimes tells you how much clock time has been spent idle, running kernel-mode code and running user-mode code. The sum of these three should be the amount of time the system has been running for.

Thank you for the kind response. I kept my application under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry key.
But still I'm under the impression that process should compare its startup time with the system up time to know whether the present startup is the first startup right after windows reboot.
Does this make sense?
I felt that it was necessary because the console application can be killed once started via CTRL+C, CTRL+BREAK, TaskManager-> EndTask. Under such scenarios in the next iterations of process startup it is not necessary for the process to do the special initialization done during the very frist startup right after machine reboot.
Thanks again & Best Regards, Renuka

This will not tell you if its first start or not. Depending on how fast or slow the system does initialization of things before it gets to the Run key, this time can be very variable.
Better to log within your initialization when the proram was started. When your process starts compare the entry to the latest eventlog entry 6009, which tells you the time of the last restart of the system. If the eventlog entry is newer than what you logged last time, it means its the first start. Otherwise its not the first.

Okay, I'm going insane. I have a Win XP Pro development machine that will not find any files when I search for them. FWIW, indexing is off on the hard drive. I don't care about performance, as I only search short trees of files.
So, I go to the top of a tree, hit search, enter in a filename that I know is in the subdirectories, press search. no results.
This has to be something really stupid. msdn searches yielded nothing... ideas?

Click Change Preferences, Change files and folders search behaviour, Advanced, then OK. Expand More Advanced Options and change Type of File to (All Files and Folders). Tick 'Search system folders', 'Search hidden files and folders' and 'Search subfolders'. Ensure the options under When Was It Modified? and What Size Is It? are set to 'Don't Remember'.
While in the Change Preferences box I click 'Without An Animated Screen Character' too.

That ("Rover") actually does not take much resources. The search algorithm itself is slower.

Yeah, I know. That's not why I turn it off. I turn it off because it's annoying.

It is slow also and none of the applications would get CPU slice. I would prefer GDC (Google Desktop Search).

Well, so far, no joy. I went through all of the settings to see if they matched up, and they did. I don't need a super efficient search. I know better than to search "C:\". My typical use is to start at the top of a source tree and see if I can locate a header file.
This is just weird.

I have developed a server and client application for lan monitoring.The problem is that I have to change the permissions of of my client application for all users, but changing permissions in all the computers is hectic task(when we have a large no. of computers connected to server). so I want to cahnge permissions from server only without going to all computers.
Is there any application to do this.
please help urgently

Hi - trying to check connectivity with tracert command

(2) how do I check connectivity to a subnet:
<br />
208.134.161.0 [255.255.255.0]
Thanks very much!

(1) That means that tracert stopped waiting on a reponse by that node because it took too long.
(2) Use Ping. ICMP Type 3 Code 0 is for "Network unreachable". You might get that reply from a chatty (not stealthy) router which realized it has no port to send your ping request to.
However, these computers could be anywhere, they don't have to be in the same room physically, so "checking for subnet connectivity" is not something you usually do.
Cheers,
Sebastian

Like the other poster said, there are 3 possibilities.
1. The 11th hop is down for some reason.
2. The 11th hop takes too long to respond, where TRACERT times out and give up waiting for a response.
3. The 11th hop is configured to ignore/drop/misroute ICMP ECHO requests.

30th hop total - what does it suggest? max depends on routing protocol? 30 seems a big number...?
