Thank you very much for your comment. But my computer do not have a numeric keypad. Do you have any other solution to solve the problem?

Thank you very much Michael, I have check my laptop and found that the number lock is turn on. Because my laptop has only the number key near the function key (F1,F2...) so I didn't check that it has design another number area on the key MJKLIOP...
Now it is working again like before. Thank you very much for your help.

our company does not allows us to access any of our mail sites...
not even google...is there a work around.
there is a site www.meebo.com by which you can access messenger...
but is there a workaround for mail sites....
it would be of great help.
ciao,

Your company did this for a reason. So, if you want to get fired, go right ahead and circumvent the block on those sites!

I just received a project notification from a ligitimate sight that matches programmers to projects. These two projects just set off all my RED flags.
Project 1:
1) A small application that is automatically downloaded to a person's desktop.
2) Records key strokes, mouse position, and URLs in IE.
3) Sends packages back to our server in text format with timestamps.
4) Security needs to be addressed if installs will prompt security notices.
5) Uninstall automatically after set time.
Project 1:
1) Read POP3 servers.
2) Modify subject header and add content to body of e-mails.
3) Post modified e-mails to localhost (Win98/ME/XP).
I can think of no ligitimate reasons why someone would need these programs. The first one sounds like a Trojan Hourse to me, and the second one sounds like a program for spamming or lunching a DOS attack.
Am I wrong?
Is there any ligitimate/legal reason for using either of these programs?

I think your instincts are right.
I wouldn’t get involved with either project.

Ya! I just hope the service takes my note, about them, seriously.

The first project reeks of spyware. "Oh yeah! We need it to circumvent all browser security!" Yeah, right... $10 Million US cash, up front, in small non-consecutive bills, ...
The second one just injects spam and adware into every email the person sends. Again, yeah, this is "useful" to all the "right" people.

Precisely why I sent the service a message!
I wonder if they have some one to read these job offers, before they are offered to us (dought it). I might not mind the job for a short while, or may be I could take the time to write a program that throws up flags based on content.
Oh, wait a minute, that's the goverments job. 
It would be interesting to see a Trojan tracked back to a sight used to hire someone to write one.

The first project requirement 4 "Security needs to be addressed if installs will prompt security notices." made me laugh.

I thought it was pretty funny myself!
I tmade me think of who could possibly post a request like that. Some 15 year old punk maybe?

as I thoutht:
an application can have many processes and then each process can have many threads. is it right??????
but, one process can only one main-thread , what about process of application???
the books i am reading syas:
"The physical separation of this memory and resources is called a process. Of course, the application may launch more than one process. It's important to note that the words "application" and "process" are not synonymous. "
thank you very much!!!

"Application" is another word for "program" or "executable", so one software product may contain several executable files. For example, MS Office contains winword.exe, excel.exe, etc. "Application" is a human concept, all that the OS knows is executables.
When you run an executable, the OS creates a process for it to run in, and creates one thread in that process that actually runs the code.

Process boundaries isolate multiple applications running concurrently on the same machine. Memory is allocated to a process and is protected from other processes accessing it directly. You can’t pass a pointer to memory to another process. One process does not access another processes address space directly. There is always some indirection between processes, either a proxy or a memory mapped file.
Threads operate within a process and all threads can access common memory within the process that created them. Variables [or objects]that are global in scope can be accessed by any thread within the process. As with functions threads can also have local variables [or objects]that are unique to the individual thread which cannot be accessed by any other thread.
When you launch a process [execute a program] the OS assigns a unique process identifier to the process [PID] and launches the processes main thread. In this main thread you can launch many subordinate threads that run more or less simultaneously. It gets a little complicated with multiple CPUs so let’s just stick to one for illustration.
When you launch a thread you assign a dispatch priority [or take the default] which determines when (relative to other threads) a thread gets CPU cycles. The thread competes with every other thread on the machine for CPU resources in prioritized queues. Dispatching can get a little tricky so that no thread gets starved but to keep it simple, and in general, higher priority threads get resources [CPU cycles]before lower priority threads.
Take a look at the Windows Task Manager [ctl-alt-del] and in the "view - select columns" menu check PID, CPU, CPU Time and Thread Count. This will show all the process currently running on the machine. Double click the CPU column header to sort by CPU percentage and you will see the processes swapping in and out and the percentage of CPU cycles they are using.
Hope this helps.

When using local profiles on XP, the first time a user logs on their profile is created based up the Default User profile (usually in C:\Documents and Settings\[User name]), and the profile is subsequently available if the user logs is at that PC again.
Is there a limit to the number of profiles that can be stored locally, or is there an overall limit to the amount of disk space that local profiles can use?
If so, how can these limits be changed?
If there is no limit, I presume the contents of the profile folder will just grow and grow the more different users log in?
Btw, I am aware of roaming profiles and that they can be deleted upon logout after their contents have been returned to the server; bandwidth restrictions between client and server dictate that using local profiles is the only feasible option at the moment.
Thanks!

Both are limited only by disk space. There is no hard-coded limit for either.

Yep! Limited only by disk space.

Entirely true. I'm one of those people who throws everything on the Desktop, so my profile is huge, weighing in at some 4.2GB. That's not something I would want as a Roaming profile. It would take forever to login and out. You can, however, limit what is copied as part of the Romain profile and limit the size of the profile itself. Keep reading and it should make mention of this. You can also find out a bit more from here[^].

I am reading a book about OS and get some problms about memory management section:
From an application standpoint, the system paging file increases the amount of memory available for use. It makes the system appear to have much more physical memory than it actually does. This is why a machine with, say, 1GB of physical memory can run many apps simultaneously, each having a 4GB process address space that is, perhaps, 50% backed by physical storage.
Conceptually, it's helpful to think of the physical storage behind virtual memory as the system paging file. Even though pages are constantly being copied in and out of physical RAM, the vast majority of the physical storage behind the virtual memory in the system is typically in the system paging file.
I am not good at english to get insight the meaning of these sentences: so ,please do make a much more easy or give me more info to understand it .
such as the " paging File" is it a kind of technique or an exactly file ...
thank you very much

In Windows the "paging file" is really a file. Change the Explorer settings to show hidden and system files, and you can find it, usually in C:\pagefile.sys. Linux normally uses a separate partition for virtual memory backing store, and it's called "swap area".

thank you first!!
yeah, I find the file and now I have another question:
1GB of physical memory can run many apps simultaneously, each having a 4GB process address space that is, perhaps, 50% backed by physical storage.
above sentences say "each having a 4GB process address space ..." as I know there
is only 4GB virtual memory but how can each app obtains 4GB... is it also means "sharing..." .
and another :
what does it mean "50% backed.." I do really understand what is happening here....

Each application has it's own seperate address space. It's alomst like it was the only application running on the system.
kevien wrote: what does it mean "50% backed.." I do really understand what is happening here....
It's just an example. Your app thinks it has 4GB of memory, when in reality, there's only 2GB of physical RAM. The other two are simulated in the swap file.
