[VS 2003] Best way to get data from text file
Just after a quick piece of advice, I'm trying to write an application that will read stored chess games in .pgn files and eventually replay them move by move on a chess board (thats a way off for now )
The advice I'm looking for is the most efficient way to extract the data from the .pgn file (this is all in plain text , see sample below). I need to get the event name, site, date, round ....etc. I initially thought of reading it in one char at a time until I hit a " then store the following characters until I hit the next " etc but this seems a bit long winded is there a better way ?
[Event "Wch U10"]
[Site "Bratislava"]
[Date "1993.??.??"]
[Round "1"]
[White "Martinez, J."]
[Black "Akobian, Varuzhan"]
[Result "0-1"]
[WhiteElo ""]
[BlackElo ""]
[ECO "C02"]
1.e4 e6 2.d4 d5 3.e5 c5 4.c3 Nc6 5.Nf3 Qb6 6.Bd3 Bd7 7.O-O cxd4 8.cxd4 Nxd4
9.Nxd4 Qxd4 10.Nc3 Qxe5 11.Re1 Qb8 12.Nxd5 Bd6 13.h3 Ne7 14.Nxe7 Bxe7 15.Qg4 O-O
16.Bh6 Bf6 17.Qe4 g6 18.Bxf8 Bc6 19.Qb4 Qxf8 20.Qxf8+ Kxf8 21.Be4 Bxb2 22.Rab1 Bd4
23.Bxc6 bxc6 24.Red1 Rd8 25.Kf1 Ke8 26.Ke2 Rd7 27.Kf3 c5 28.g4 Ke7 29.Rb8 e5
30.Rh8 e4+ 31.Kxe4 Bxh8 32.Rxd7+ Kxd7 33.Kd5 Kc7 34.f4 Kb6 35.Kc4 Kc6 36.h4 f5
37.gxf5 gxf5 38.Kd3 Kd5 39.h5 c4+ 0-1

Re: [VS 2003] Best way to get data from text file
Use Streamreader.ReadLine & split(""""c) on the line [Event "Wch U10"] gives you this string array
("[Event ", "Wch U10", "]")... Then get the 2nd element from the array.
VB Code:
Dim line As String
While sr.Peek <> - 1
line = sr.ReadLine()
If line.StartsWith("[") Then
strWhatYouNeed = line.Split(""""c)(1)
End If
End While

Re: [VS 2003] Best way to get data from text file
Thanks for the help it works great
I've looked at the dynamic help on split but it really doesn't explain in great detail what's going on, could you tell me what then 'c' does in the split arguments.
