<0> I did get a few corrupted files before this happen
<0> do you thnk it is the harddrive or ram or the mb ?
<0> the MB is an intel mb...
<0> not msi or abit or any other popular brand
<1> darklling: try newegg.com
<0> ok
<0> wow, big page
<0> wow, cheap
<0> :D
<0> hmm I just have 533 mhz ram, and the MB can handle 800 I think
<2> hi all
<0> hi frater :-)
<3> hey WraithX
<3> what is it about jazz that makes me need to drink wine
<4> Too ****ing early to be at work.
<4> Really.
<3> how early Drk`Angel?
<4> 7:15 now. 6:55 when I got here.
<3> yep. definatley too early
<5> hey ;)
<6> barbiejuudo
<5> -.-
<5> i must admit, never heard that one ;P
<0> Kenjuudo:;)
<5> joepezt ;P
<7> how can i tell if the object has been created ?
<7> *cl***)
<0> ^^
<0> Kenjuudo, se priv
<5> ok
<5> yuri`: note that you should allways set an object reference to nil when you destroy it... that way it's easy to see if it's created or not -> nil or not nil
<5> that's also why sysutils.pas has a freeandnil() function
<5> object references are in reality just typed pointers (though they can't be dereferenced)... when you call a cl*** constructor (usually create()), it allocates the memory needed to hold an instance of the cl*** (called an object), clears it according to defined and ***igns the memory address to the object reference (your object variable)... now it's ready to use... the destructor does, however, not clear the reference variable afterwards... y
<7> Kenjuudo, yes but its not possible
<7> because i cant nil the object inside the cl***
<7> i tryd sizeof(object(
<7> maby the size is changing.. but its the same
<5> sizeof(<pointer>) allways return 4...
<7> Yes
<7> there are many cases the cl*** will destory it self, so i cant track outside
<2> ok problem: application is hanging and doesn't close - what are likely causes?
<5> WraithX: doesn't process messages?
<2> seems not - it just hangs there and won't take any input
<2> the IDE can't do anything with it - and when I pause it, it gives an AV but doesn't show where
<5> yuri`: in other words; your variable occupies 4 bytes of memory... these 4 bytes contain the address of the actual object instance, and it's real memory size is "none of your concern", because it is managed by delphi
<7> Kenjuudo, can the cl*** know its holding varble ? get the memory location or somthing ?
<7> in other way to say it, is it the oly way to do it by nil ?
<5> WraithX: AV = access violation... translate that literally into your (human) language of choice... because what it means, is that you try to read from and/or write to memory areas not defined for your application
<2> yes - I realise, but this only happens after the hang - and I need to know is what might cause such a hang
<5> yuri`: the cl*** is (almost) just a type declaration... but neither does the cl***, nor the instance know if you have any variables pointing at it's location...
<5> WraithX: it doesn't process messages...
<2> what would stop it processing messages?
<5> WraithX: some infinite loop somewhere?
<2> I can't find any infinite loops
<2> in the various destroy methods
<7> Kenjuudo, is there another ways to know is the cl*** has destoryed, ?
<7> was*
<5> WraithX: there can be a multitude of causes... my suggestion is that you look into your thread logics... it's multithreaded, yes?
<5> yuri`: note that the constructor in reality acts just like a function... it returns it's address pointer typed with it's cl***
<5> yuri`: it's your decision to put that address into a variable
<5> yuri`: like this: bmp := TBitmap.Create;
<7> I dont see it in my naked eyes
<5> o.O
<7> Oh
<5> yuri`: that's why it's possible to do like this: TBitmap.Create.Destroy;
<2> ken : yes - multi-threaded
<5> though that'll make no sense ^^
<7> maby ? bmp := TBitmap.destroy ?
<5> yuri`: no, Destroy() acts like a procedure
<5> just do: bmp.Free; bmp := nil;
<5> or FreeAndNil(bmp);
<7> the free goes inside the cl***
<7> its tcp socket thread it destory it self
<5> ok... im probably not following you clearly enough... -.-
<4> tsk tsk, objects shouldn't destroy themselves.
<7> who said so ?
<5> WraithX: take care that the threads doesn't access the same resources without proper gating...
<4> yuri`: You should be saying so yourself. If it destroys itself, it is impossible to tell from the outside if a reference is still valid or not, short of accessing it and seeing if you AV.
<5> WraithX: a thread should allways be 100% sure when accessing another resource that no other threads is doing it at the same time
<7> there must be cases when it has to destory it self, but you are right
<4> Should never destroy itself.
<4> Send am essage to the owner saying "I'm done, get rid of me whnever you want"
<4> The only possible time you might want it to destory itself is if no references to it exist, and you're sure about that.
<5> yuri`: there are plenty of cases where an object must destroy itself... but since it causes the code it currently executes to be invalid memory (ie: you'll likely get an access violation), you'll allways have to find a way where you destroy it from somewhere else...
<6> besides, suicide is a sin :P
<5> hehe
<7> k
<7> thanks
<5> np
<5> have fun... make doom 5
<7> lol
<4> Its possible to self free without AVing.
<4> See: TThread.FreeOnTerminte
<4> Just you shouldn't do it often.
<7> can you tell me about abstract use, i read about it, but didnt understand it really
<7> in short of
<5> yuri`: an abstract cl*** is (in delphi) a cl*** with abstract methods, or which inherits abstract methods from it's base cl*** and doesn't implement them... and there we have it... abstract methods are just methods without implementation (ie: no code)... though you can't create instances of abstract cl***es, you can derive new cl***es from them and implement the missing implementations... these new cl***es can be instantiated ;)
<5> they are good for telling derived cl***es that they NEED those methods...
<4> You can, actually, instantiante an abstract cl***. But you really shouldn't. :)
<5> heh... never tried ^^
<4> Don't get an EAbstractError until you try to call an abstract method.
<5> oh my... i tried once... tried to create an instance of TStrings ^^
<5> you get a warning at least
<4> Yeah, I made that mistake a few times.
<4> :)
<5> :)
<6> find it weird that you can instantiate cl***es with abstract methods as strongly typed and anal delphi can be at other times :P
<4> ootje: Yeah, I agree
<5> delphi isn't a language... ^^
<6> Kenjuudo: stop being anal :p
<4> Actually, it is. Its Borland's take on Object Pascal. It is no longer object pascal, as it has a ton of Delphisms in it now. ;)
<6> yeah i was going to say that
<6> just wasnt sure of what to use as an example :)
<4> Its been so long since I wrote in pure pascal I couldnt' come up with any either :)
<8> hello
<8> Do you know any expert/addon that would increment build number when compile (D7)? Gexperts seems to work with D6 only.
<6> doesnt it do that manually
<6> `?
<6> er automtically
<4> Nick2: It does that automaticlly.
<6> build+compile
<8> when you build, yes. when you just compile, no
<4> That's why its called a "build number"
<6> Nick2: thats kind of the concept with BUILD number
<8> I don't want to build all times to increment it; sometimes is useful to have a diff build number on compile
<4> Yeah, if you like abnormally large build numbers for some reason.
<6> i know a lot few compilers/linkers use days-since-year-2000 as build nubmer
<8> for debug reason it's useful
<6> i have some code for some linker stamp updater.. maybe you can hax0r that code
<8> I can giove it a try
<6> couldnt find the url so here's my copy of it, http://dev.never.no/~rune/PEStamp.pas
<8> thanks
<9> that's a riot, rapper/actor ice tea on tv talkin about making a new "body count" album, he's like "bush is in office ****in up the whole world. we couldn't make an album with clinton in office. how you gonna make a body count album with clinton in office? clinton should be on spiketv with his own lapdance show. everyone was happier with clinton in office"
<5> "clinton is in office ****ing up monica"?
<9> gittin his **** ****ed definately didn't start any wars
<5> i don't see nothing wrong in having high bodycounts
<10> isn't there some research that suggests male aggression is related to ***ual frustration?
<11> hmm when first iraq campaign was started?
<10> daddy bush
<5> does bush have kids?
<10> doesn't mean he was getting any when he decided it would be a great idea to invade iraq
<12> re
<11> oh, i forgot then... thought is was right after that clintonjob incident
<12> if in an application i use the twain32 driver for scanner and if the application stop how can i restart the driver scanner?
<10> that was why he was accused of finishing his father's work
<12> which component free o gpl to create thumbnails in gelphi?
<12> ops delphi
<13> Good morning.
<5> sg-sg: explain what you want to do...
<14> How to make service app?
