I see... so this will run it on another thread basically and I can see the start and stop points. Well I was trying to figure out how to see how much bytes have been written to the SQL database somehow. Sad there isn't something to do it...

hi ,
i'm creating an application that's checks if a blank dvd is inserted in the drive.
i want to prevent that my application is closed by a user using the task manager.
- i've tried to use code injection to Task manager to hide my process from the process list but this solution closes hides other processes but not mine.
- i've tried to use a windows service to verify if the application is still running and to restart it if it is closed ,but shows me the application in the process list but there is no UI.
- I tried to impersonate the code to a higher level user ,but this returns an exception because i'm trying to instanciate "MsftDiscMaster2 discMaster" : discMaster.IsSupportedEnvironment is always to false.
Thx

I doubt this is possible. I recall seeing this question a couple of times and the general consensus was that it can't be done. Also, your service could be disabled.
Off topic, but why do you want the user not to be able to kill your app? I would generally consider that very hostile behaviour and make sure I remove every trace of it.

the problem is that only the administrator could be able to close the application.
This application should record every dvd or cd burning action.
that's why i don't want the user to be able to close this application .
To burn a dvd or a cd the User should unlock the dvd burner using this application .
if i tried to run the application in the User account and there is a problem using the isolated storage and the IMAPI2 .

Maybe when the form is closing you could run another process of that application unless it was closed by a certain user? (Environment.UserName)

Well, if thats that then make a formless application, name it 'svchost'. Since too many processes have the same name, it will be hard to know which one is yours and if someone closes the wrong svchost process then I'm sure window will react strange and will require a restart. Thats the way I use...;)

since the user is not an administator , i'm managing to create a batch file that runs this application at windows startup using the runas command with Administator privilege.
This way , the user cannot stop the application using the Task manager , the UI for this application is visible and i've change the security policies to disable the regedit .

hi
your problem has been solved by me
i have a program that nothing can close it
and it can watch your application and when something closes it my program
will restart it agane
all you have to do is send me yor application process name(the one that apear in task maneger) and your application path (like c:\windows\myapp.exe)

I want to extract attachments from a PST or OST file from C# code and save the attachments to my local drives. I use OUTLOOK 2003 with the exchange server.
Any idea is appreciated.

I've written some code that takes 2 or more files and joins them together into a single file, essentially duplicating the functionality you see when you use the DOS copy /B file + file + file outputfile command. The problem is that it takes what I consider an exorbitant amount of time to perform this action. Granted the source files are as big as 1gb in size, but it just seems to me that I can make this process faster, so I'm here asking for possible approaches to the problem.
Essentially, I'm opening up each source file and reading blocks of the file at a time, and then writing to the target file. Due to the total size of the target file, I can't simply read in the entire set of files at once (as big as 8gb) and then write it out all at once) I've tried 256k blocks, 512k blocks, and 1mb blocks, but they all perform about the same (no empirical data to back this up, just an "impression"). Is it better to go with reading larger blocks or smaller blocks? Anyone have any insight?

Are you doing the read and write synchronously? Did you try using the asynchrounous BeginRead/BeginWrite methods?

For maximum performance I would:
- not use .NET File and Stream classes, instead use low-level Win32 file operations (CreateFile, ReadFile,...)
- if coding in .NET make sure all buffers are managed, and marshaling is not copying data, just passing pointers (use byte[] and GCHandle)
- try and get the files NOT cached (don't recall how that was done)
- use two separate disks, one for source, one for destination
- transfer a moderate amount of data at a time, try and make it an exact multiple of the cluster size (if unknown try 2*3*5*7*11* 64KB)
- make sure system activity is low (i.e. no other disk accesses)
and for file concatenation I hope each file's size is a multiple of your sector size (512B), if not can you accept padding? when unaligned with respect to sectors, I would compensate for that on the reading half of the code, i.e. as much as possible write at file address that are multiples of 512.
What are the copy numbers you are getting (MB/sec)? you should be able to achieve 30MB/sec on moderate hardware.

By passing FILE_FLAG_NO_BUFFERING to CreateFile perhaps? I never tried that, maybe it doesn't work, but it sounds like it has a chance

this is reading all text and throwing away all but the last line.
You need to read and store all lines in memory first, in the Load handler. File.ReadAllLines can be used for this.
Then set your Control's Text property to whatever you want it to show; probably do this in the tick handler.
FYI: You could do without the string array, keeping all text inside the Control, but that is much harder to do correctly.

Hi
in sql server, u can set some extra properties to any object in database (like description).
u can query for this ExtendedProperties via this command :
SELECT o.Name AS ObjectName,
o.type AS ObjectType,
s.name AS SchemaOwner,
ep.name AS PropertyName,
ep.value AS PropertyValue,
ep.major_id As ObjectID,
c.name AS ColumnName,
c.colid AS Ordinal
FROM sys.objects o INNER JOIN sys.extended_properties ep
ON o.object_id = ep.major_id
INNER JOIN sys.schemas s
ON o.schema_id = s.schema_id
LEFT JOIN syscolumns c
ON ep.minor_id = c.colid
AND ep.major_id = c.id
WHERE o.type IN ('V', 'U') and ep.name <> N'microsoft_database_tools_support'
Howeve, i'm looking for a way to retrieve this properties via this code :
this.Text = this.users.ExtendedProperties["MS_Description"].ToString();
Is there anyway to do this ?
Thanks

If you parse out the ProprtyValue field (I assume ms_description is in there) I see no reason you can't do what you want. You could create a method to support users.extendedproperties to support ["some property name"].
AFAIK there is no internal method to do this.
[edit] It would make a useful article as well [\edit]

Thanks Mycroft
i know it'll be implemented by providing a method, but i think Ado.net has easier way to do this automatically, but how to do ?

You have probably already considered this, but from some time ago, when I was playing about with some of the SQLServer samples, I remember there being an ExtendedProperties property which I think was a ExtendedPropertiesCollection. All of this was in the SqlServer.Smo namespace, if memory serves.

Here be dragons. So you want to make a use configurable form, I'm sure there are articles which will help you with this BUT be very sure you want to pursue this type of app before getting any deeper, this needs some very strong business reasons for developing such a beast and you will NEVER be satisfied with the result until you build another IDE.
