<0> hi
<0> im trying to use FileStream to copy a string.... but it supports only byte[]... so what can i do?
<1> convert the string to a byte[] ? :)
<0> how?
<1> you have to select encoding mode, well, there's an encoding cl*** which does it
<1> if you want utf8 you use that cl*** etc
<1> lemme check the actual cl*** names
<2> System.Text.Encoding
<1> right
<2> it has a static property
<2> for utf8, ascii, unicode (16)
<1> right
<0> the FileStream only gets byte or byte[]
<0> i want to use a string to hold the data
<1> so System.Text.Encoding.ASCII.GetBytes(mystring); will return a byte[]
<0> and this byte[] is the same string?
<1> well depends on the contents ;)
<1> but yeah
<0> FileStream.Read(...) gets only the byte[] so you tell me to convert my string to byte[] and give that to the filestream?
<2> yes.
<0> ill try :)
<0> thanks
<0> i started to write a foreach loop O_o
<1> ziv4: what i was trying to say was that if the string contains say russian, some letters might not "survive" the conversion to byte[] if you use ASCII
<2> might -> will
<2> ascii cuts off the top 128
<1> if that is a concern, consider using UTF8 (you'll need to convert it back FROM utf8 when reading the string)
<2> or "Default
<2> which uses the system encoding
<0> ok
<0> i use hebrew
<1> youll most likely want to use utf8 then
<1> that'll work
<3> need TcpClient help!
<3> http://www.pastebin.ca/319371 DownloadArticle() creates/executes the Thread, Transfer() is what happens in the thread
<3> Stream.Read() causes a blocking calls exception
<4> meeeh. is there some version of an event that if signaled twice will also trigger two consequtive .wait()s ?
<2> you mean like a Semaphore
<2> ;)
<4> that might as well be what i mean yes
<4> well i use an event from one thread to tell the other thread that something is available
<4> however, if the other thread cant eat those away fast enough it locks up waiting :P
<2> why not just eat all there is
<2> after you get an event
<2> and wait again and do the same.
<4> i needto know how many there is
<2> you don't?
<2> how do you know what to do
<4> weeell, im not explicitly keeping track of it
<4> althought i dont see how a semaphore would work here
<2> you can trigger a semaphore multiple times.
<4> but you normally get and release semaphores dont you
<2> you cna use it both ways
<2> both mutex and event is based on semaphore.
<4> hm im just curious if im doing something else stupid here now anyhow x)
<4> wasnt working even if i "triggered" the event manually with a timeout
<2> :)
<4> but i guess i should look into using a semaphore anyhow..
<4> because well. what happens in this case:
<4> 1. thread 1: event.Set();
<4> 2. thread 1: event.Set();
<4> 3. thread 2: waits..
<4> 4. thread 2: waits..
<4> will #4 hang?
<4> AutoResetEvent
<2> sorry.
<2> busy.
<4> that's ok
<4> ah race condition in updating a variable...... forgot some locking somewhere i guess
<4> regarding the 1.2.3.4: YES, will hang:P
<2> 3,4 will hang obviously
<2> why shouldn't it?
<2> Only one of them will trigger
<2> if you trigger it again
<2> the other
<4> 3 wont hang, 4 will
<2> if you only set it twice
<2> the 3'rd will block
<4> thread 1 sets it twice, then nothing waits, then the 1st wait (3) by thread 2 will obviously not hang
<4> but as it is reset by 3, 4 wil hang
<2> oh yes
<2> but I meant
<2> multiple can WAIT
<2> it just can only be triggered once.
<4> sure
<4> but in this case only one thread was waiting
<4> and would be waiting
<2> thats why you normally use a semaphore
<2> when multiple are involved
<2> as it can be triggered a lot of times.
<4> yes im looking into that now
<2> it's 2.0 btw.
<2> semaphore.
<4> yep
<4> hmmm
<4> ok so ".Release()" acts as setting it then?
<4> trying to wrap my head around this
<4> http://pastebin.ca/319507
<4> im not sure why that works, but it does (when i uncomment the second release)
<2> Read the help file? :)
<4> hehe
<4> yeeees well i think i had it understood backwards
<4> thinking of it as a critical section instead
<2> it can go either way.
<4> aaaargh. snow again outside :(
<4> it's winter and spring every second day here now :\
<2> heh
<2> it's weird here too
<2> this morning I was walking in direct sunlight.
<2> It's almost dark now
<2> raining
<4> ah, well its snowing here now.. yesterday was sun and spring
<0> hello
<1> hi
<0> i want to know if there is anything in .net that find a pattern in strings
<0> like XX:XX:XX
<1> regexp
<0> works good?
<1> yes
<0> perfect :)
<0> thx
<0> it return indexes?
<1> it can yes
<0> great :)
<1> http://www.regular-expressions.info/dotnet.html
<0> can i say thx again to you?
<5> Hello, wondering if anyone could point me to a irc client in c# that have ssl implemented, since i would like to see how they do it ;)
<1> ziv4: well... ok :P
<0> so THX so much :)
<0> i was going to spend some time to make this thing
<0> but if it exists why should i?
<1> ziv4: especially since the regexp stuff is pretty fast
<1> and simple
<5> LordCrc you dont by any change have a anwser to my question? ;)
<1> Nozz: nope, dont know of any irc client code, especially in c#
<5> sad
<5> i found a few libs that do it well
<5> none of em have ssl support tho
<5> which is what i wanna look at
<0> source of c# irc client with ssl option... sounds too much specific to me
<5> :P
<0> i cant understand the language of regex
<0> \d is for any number?
<1> digit
<1> ie 0 or 4
<1> you want to extract an ip address written in hex?
<0> single character
<0> no
<1> oh
<1> just a guess :)
<0> im extracting time from something
