Chain some streams together. You want to write your data to a compression stream and feed that to an encryption stream.
Going the other way read from a decryption stream to a decompression stream to a normal stream.
This http://support.microsoft.com/kb/307010[^] tells you about encryption streams.
Off the top of my head I believe there is a compression stream somewhere in .NET2.0. If not the free assembly ICSharpZipLib has what you need.

My question pertains to the native code.
When i underwent the following line ----
When you compile code that uses the .NET Framework library, you don't immediately create operating system–specific native code. Instead, you compile your code into Microsoft Intermediate Language (MSIL) code. This code isn't specific to any operating system and isn't specific to C#.
Just-in-Time (JIT) compiler compiles MSIL into native code that is specific to the OS.
I understood that native code is the binary code (0,1)
Am i right ?
If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Not really, no. Binary is a number system. Native code is referring to Machine Code[^]

Hello,
I am using Domain Specific Language(DSL) tool to create some task flows.
We can add Icon Decorator in DSL designer which can contain an image but this image can not be modified at run time.
How should i make sure that the DSL can supply the default image as an Icon Decorator but it can be overridden at run time?
Thanks.

Getting the current cpu temperature is proving very very difficult.
Ive looked into WMI which although there is a WIN32_temperatureProbe [CurrentReading] this is not currently
availble (future production) or is very limited to certain boards.
So Ive hunted around and come across that I can get the information via Ring0 access!
Great! errrh.......what do I do?
So I havent found any info on how to actually program this (apart from c# wont work with it).
I really just want a assembly object that my c# can call
1.amount of cpu(and cores)
2. cpu temp?
has anyone or does aanyone got the know how on how to do this?
being a c# and vb programmer my knoweldge is limited.

ring0 basically means kernel level in windows world, which is to be expected if you want to query hardware properties and state. you have found the way to interact with kernel through

. You can't improve much on this, and not at all in managed code.
CPU usage is another thing, which u can access through managed code(c#). Try looking into System.Diagnostics namespace especially PerformanceCounter class and related.
there are no facts, only interpretations

Hi, nah dont need usage just need temperature for each cpu.

If you are using Sql Server 2005 you can use DateDiff[^]

U can Put the value of Birthday and Reminder on Veriable then U can Easily Companre .
Else
u can use Datediff function

can i take ( 2/13/2008) - 3 days..
i cant use the datediff to deduct..
please help..
|
|
|
|

Put the Value of Date in DateTime Variable
Then U can easily deduct date value
Like
Dim var_date as datetime
Var_date = "2/13/2008"
var_Date = Var_Date.days - 3

hi all,
I am a beginner in C#. I want to Send and receive files through parallel port. Since i am working in Windows 2000 Professional, I used Inpout32.dll for parallel port access. I used 0x378(data register)(888) for sending and 0x379(status register) for receiving. I can send data as 1 byte . But on receiving side, data received is different.
Eg: If i send 1 , i will get ---- as 136
for 2, i wil get 144.
for 15 - i wil get 0.
Does anyone can help........?
Thanks

Hi,
Some of the status inputs are inverted...
Here is a link showing which ones are.
http://www.doc.ic.ac.uk/~ih/doc/par/[^]
Also... there only appears to be 5 inputs... so how can you receive 8 bits (1byte).

Thanks Matthew.....
then, how would i get the data?
i wan to get the data i sent. On sending, we send as 8bits.(1 byte).
How can we receive tat data using 5 bits?
any idea...?
Please help yar..........
Once again Thanks..................

If your are using a DB-25 port then...
According to Wikipedia... (Quote)
<br />
Monodirectional parallel ports<br />
In early parallel ports the data lines were monodirectional (data out only) so it was not easily possible to feed data in to the computer. However, a workaround was possible by using 4 of the 5 status lines. A circuit could be constructed to split each 8-bit byte into two 4-bit nibbles which were fed in sequentially through the status lines. Each pair of nibbles was then re-combined into an 8-bit byte.<br />
The general idea with parallel ports is that you only send 'Data' in one direction (away from the computer) and only send back status bits.
When you receive data it shouldn't go 'into' a parallel port, it should be read (all 8 bits) onto the controller (microcontroller etc) port.
When sending data back, 4 bits of the controller's port should be connected to four of the status bits (see wiki page) and then the fifth status bit could be used to say which nibble (half-byte) is being sent.
To summarise...
The computer (the master) has 8 bits output, and 4 (or 5) bits input.
The device (the slave) will have as many pins as needed (8 bits receive, 4 (or 5) bits send).
You need to send data from the slave to the master in two (half-byte) sections.
[Also: Is there any particular reason why you are using parallel ports? (Serial is really simple to use)]
Hope this helps.
Matthew Butler

Thank u dear...
as u said, serial is better. But i used to transfer data between an instument and Computer via parallel port(Since interface provided by the instrument is Parallel Port (db 25 pin connector), i have to use this port for data transfer)...
Once again,
thank u for ur reply

How do I find a memory leak in C#, I have several hundred datatables I load data to. On shutting these datatables down I do not reclaim all the memory it used while loading, I probably loose about 50% of my memory.
Thanks in advance,
Michael
