I am a bit confused about the whole CAL thing and was wondering if anyone could enlighten me.
The current system architecture is:
Windows Server 2003 server with SQL Server 2005 Express installed on it.
A main service runs on the server which reads and writes data to the database. It also recieves and distributes information to some other services running on the server.
External devices, e.g. GUI's and output displays, connect to these services to send and recieve information.
My query is obviously "How many CAL's do I need?". Having looded around abit, I don't believe we need any for SQL Server 2005 Express (only the Standard and Enterprise editions), but do we require a server CAL for each external device that exchanges data between our services running on the server?
Thanks for any help.

Me and My friend has operating syaytem windows xp proffessional service pack 2.I connected my hard disk as a slave to his system. After booting syatem recognizes his all the drives but mine only c drive is recognized by the system. if i click that drive it is giving me a message box saying
"Do you want to format the drive" with yes or no option.. What is the problem..?? Why his sytem is not detecting my hard disk..? Plse reply.. Thank you..

the file system on the partition you want to read from is not compartible or the harddisk partition is simply not accessible.
Alternatively, do the reverse, master your harddisk and slave your friend's.

I just came from a meeting, we're creating a new VPN solution for the company. I'm on the Quality Assurance side.
During the meeting someone mentioned something about an S-N-X connection. Can anyone clarify, I think I understood it incorrectly, i'm hoping someone is familiar with Networks and what not that can point me to the correct terminology.
Thanks.

All, I thank you for checking, would it make sense if they were simply referring to 100BASE-SX aka Fast Ethernet?

Dear All
We have one time critical program on windows 2000 service pack 5.
Our Threads should be run in exactly predefined time slots.
But in our program, I find that sometimes, Our threads blocks and doesnt work.
We make our threads with very high Thread priority(25,26,27,28,29,30,31).
It is not accepted for me that any program blocks my time critical program.
Do you have any idea about this problem and how to overcome this.
Regards
Monhi

Someone else can probably give a more definitive answer, but I believe in Win2000 hardware interupts always trump even the real time thread priorities. In other words, it ain't really real time. You may also be competing with other system processes that are running at the high priorities you have selected.
|
|
|
|
|
In operating systems:
1- Hardware interrupts have the highest priorities and you can't disable them in win2000 because its multitasking and doing so harms the scheduling using the clock interrupt!
2- Process Managers and Reincarnation servers and memory manager have always the highest priorities so you cannot beat them!
To follow the path, Walk with the MASTER, See through the MASTER, Be the MASTER!

Basically, what everyone is telling you is that you cannot do this in Windows. You're writing code that requires a Real Time operating system, and Windows isn't one of them.
|
|
|

Interrupt servicing and Deferred Procedure Calls pre-empt ordinary threads in the Windows NT scheduling model. DPCs are a way for device drivers and other kernel-mode code to defer processing of device interrupts to a later time - the interrupt service routine (ISR) typically does enough to acknowledge the interrupt (stopping the device from interrupting) and schedules a DPC for later on to actually handle the I/O request. All DPCs for the current processor are processed before returning to user-mode.
Typical Windows device drivers are not designed for real-time operation - their operations are not predictable in time. Video and sound drivers are typically particularly bad in hogging the buses and doing too much work in one go, rather than breaking a complex operation into a lot of small steps (allowing other work to happen).
If you want to stick with the Windows family, you have a couple of options. You can get a real-time extension for desktop Windows such as RTX[^]. Or, you can build your own Windows CE[^] platform. Windows CE is designed to be real-time, as you can control scheduling of device interrupts versus user threads. This is because the interrupt model has an Interrupt Service Routine which is solely responsible for clearing an interrupt and setting an event object; that event object wakes up a regular Interrupt Service Thread which is scheduled against all the other threads in the system.

All the documents I have read relating to this topic have left me with gray hair, so I hope somebody here could clear things up a little.
Using the DeviceIoControl() api I can get a NTFS_VOLUME_DATA_BUFFER structure. This structure lists 3 MFT regions ( MFT, MFT2 and MFTZONE ). Each of these regions start at different points on my HD.
Correct me if I'm wrong:
1. The MFT size ( in clusters ) is MftValidDataLength / BytesPerCluster.
2. The MFT2 size is the same as that of MFT.
3. The MFTZone size is MftZoneEnd - MftZoneStart.
Here is where I am confused:
From what I have read the MFTzone is space to be used last to help keep the MFT contiguous on the disk. This leads me to think that the MFT and MFTZone should start at the same cluster, or the MFTZone should start immediatly after the MFT. Why is my MFT located towards the beginning of my volume and the MFTZone towards the end? Is this because at some point it became fragmented?
I have also read about an MFT mirror. Is this the MFT2 above? Regarding this I have read that it's size is the larger of the first 4 records in the MFT or the cluster size. How exactly can I calculate the size?

I seemed to have answered some of my own questions by opening the $MFT and $MFTMirr files. From what I have found, the NTFS_VOLUME_DATA_BUFFER structure is only useful for finding the MFTZone. The position and size of the MFT2 can be found by opening the file and getting it's retrieval pointers. Also this file seems to always be contiguous.
The MFTstart member of the struct only points to the first cluster. By opening the file I have found it to be heavily fragmented ( 11 fragments on my C volume ). As to what the validDataLength member means I have no clue.
I can only guess that the position of the MFTZone reflects where the next fragment of the MFT would be located if it were required.

Hi,
I'm developing an add in for Powerpoint and i have run into some problems.
Powerpoint has opened a file which i need to replace (the file in question is a simple data file).
my app runs as an add in (dll loaded by powerpoint). so i should be able to close the aforementioned file from within powerpoint. i have seen some tools do this.
can anyone help me with unlocking the file (closing).
thanks

You have to replace a datafile that PowerPoint has opened?? What file is that?? Part of your presentation??
There is no way to SAFELY close the file without crashing the app that has it open. You didn't open the file, so you really don't have the rights to close it.

the file in question has been opened by a flash component inserted onto the slide.
during slide show when the flash component is active it opens the file. after slideshow it no longer remains active but doesnt release the handle it opened earlier. is there some notification from powerpoint to flash object when slide show ends, so that i could manually close the file.
|

You opened this Flash which in turn opened the data file. Why would you expect Powerpoint to then close a data file it never opened?

its right that i opened the file inside flash. but what i am expecting is when the slide show is over does powerpoint give me (Active Object : flash in this case) any signal that Show is over and you need to deactivate?

If you're using PP2007 then goto the developer tab and select controls on your ribbon. You should be able to find a control for what you want there...hopefully.
