<0> which is a stupid concept anyway
<0> doesn't contain anything
<0> moonlord: http://www.imdb.com/name/nm0032375/
<1> why is it stupid?
<2> just read the records the way they are now and put em out in another record type either way
<3> cute
<0> :)
<3> but i don't need more series to watch, i need less!!!
<3> :p
<1> did you like Jericho, ki9a?
<0> no
<0> you ?
<4> in other words i must try to open the file changing my record structure until i get my program working?
<0> moonlord: but you can get this on dvdbox :)
<1> yeah i liked it
<0> aMDS: you should use a database.
<0> they're made for that
<2> record first,last,adress,city:string[15];state:string[2]
<2> or sumpin like dat?
<4> ki9a: y but i'm trying to create a program compatible with another one
<1> although, i think there is a lot more room to turn the story to ****, than most programs
<0> oh yeah
<1> i might not like it 2 or 3 episodes into it though
<1> aMDS: probably better to create a new database, then create a database converter for it
<4> y but i don't know how to convert for it because i don't know the record structure
<4> this is the problem
<2> still need to know the structure commin and going
<0> it's not a problem
<1> how do you even know it has a record structure and its not a database format?
<0> if it's a file of record
<0> you just have to do some trial and error
<2> if its a file of record you gotta know the record type
<1> exactly
<0> just look at the file
<0> and check how it's stored
<1> how can you know that its a file of record, without knowing what record is?
<2> yep usually find the size of the records right off
<1> still better to use a TFileStream :-D
<4> Rahly: because i've created a similar record
<2> recuring 00 so many bytes apart...
<4> but i don't know how to complete mine record
<1> aMDS: and?
<1> k
<2> yo can factor the filesize too
<1> weird, must be an old app
<1> most database files have keyblocks
<1> they aren't just a flat file
<2> you talkin sql... list of lists then?
<2> bit harder to figgure then
<1> na
<0> you don't generally "reverse" a db file.
<0> you just use it.
<1> depends on the db file
<1> thats generally only recently too
<0> maybe btrieve :)
<1> last 10 years or so
<2> yup just get the record ya want
<2> all the keys and sorts and pointers already done
<1> b,b+,b*tree don't store column names and types, thats something a database ENGINE does, not the files
<2> what was the question?
<0> is there one?
<0> And I was thinking we were just haviing a pointless discussion
<2> something about reading a file record as record
<1> you pay the midgets to do it by hand
<4> i want to know how can i recreate the record structure
<1> TRecord = record { Insert Fields here} end; // voila
<4> eheheh
<4> but i don't know every field
<0> with patience.
<1> and a good hex editor
<0> and trial
<0> and error
<0> and more error
<0> How many records are there?
<0> divide the file size with that
<0> and you at least know what the record size is.
<4> i know the record size
<0> so what is the problem ?
<4> this isn't a problem for me
<0> Just read it all in a byte array
<0> and find out what the stuff is
<0> you don't kno.w
<2> godd txt editor usually works... gotta tell it not to have insert on and not to pad or add crlf and word wrap
<0> hex is most useful
<4> Petety: y i'm using it
<0> since < 32 is sorta unreadable in notepad.
<4> but how can a know that is a boolean and not integer?
<4> i know*
<1> you can tell
<1> but ***ume an integer until you know more
<2> bool is ff and 00
<1> you can fake it as a boolean when you know exactly what it is
<5> a boolean will have two values, and integer has more different values and takes way more space
<1> Petety not always
<5> Petety not always
<2> true can get 8 booleans in a byte if they pack
<5> it depends how the databse stores it, but again, really easy to figure out
<1> esp in a record system
<2> and if ya know the record size its a no brainer
<1> get a listing of all the values in a field in all the records, and you can usually figure it out
<2> just need most of the feilds really
<1> for example if they are all, 1 and 0 or FF+ and 0, then its probably boolean
<4> can i link the forum with hex code?
<2> havent programmed in hex since the z80
<1> link the forum, eh?
<1> you can paste links in here, thats ok, if thats what you mean
<2> som of the stamp cpu's are pretty easy in hex
<2> like 10 op codes
<4> http://www.rafb.net/paste/results/hJFbrO72.html
<4> this is a sample record
<4> opened with a hex editor
<1> looks pretty simple to me
<4> y because there are many string
<4> but there are not only strings :(
<2> 4 text feilds and a couple numerics at the front
<4> here is the original topic http://www.teamspeak-einstieg.de/index.php?name=PNphpBB2&file=viewtopic&t=2940&highlight=udp
<4> Petety: 5 text fields
<2> so the first 21 bytes are # or bool
<2> and all the rest is txt
<4> y i know
<4> but for example
<4> what is F4 BE 03
<4> i don't think that is a boolean
<2> account number ? number of fish in the aquarium?
<2> amt opf tax owed?
<2> gotta know what to expect... theres gotta be a reason for the numbers
<2> the # may be in byet order rather then word
<2> f4 be may be 256 *be + f4
<6> FF = 256
<0> or a float?
<2> 03 +256*0 for 3
<6> 255.. but 0 is counted
<2> float is usually more non zero bytes
<2> very seldom se a float in a db
<6> (256*0)+3=3
<2> pennies are usually int / 100
<2> db usually has unsigned int
<2> one col credit, one debit, think accountantspeak
<0> hrmm
<0> VLC is slow at starting dvds
<2> floats round and accountants dont like that
<1> ff <> 256 ff = 255
<1> i like how people think floats are "inaccurate", i think thats funny
<0> they just cannot represent everything
<1> kinda like how we represent 1/3rd as .33333
<1> the inaccuracy comes from the conversion from the float to a printed value on the screen
<7> http://noname.c64.org/csdb/release/?id=38967 great c64 pic
<7> woo and http://noname.c64.org/csdb/release/?id=37677
<1> c64 brings back so many gaming memorys
<1> one of my fav was Sid Meier's Pirates!
<7> aye
