Trigger an event from a pokerstars hand completion in vb.net

 This will search the Pokerstars hand history folders on your comp and trigger an event when the size of one of those hand history files changes.

I set the timer to 3 seconds and get NO processor spike at all and it catches every append to pokerstars HH files in as many tables you are on. If you plan on parsing hands just split the string in the streamreader with (vbnewline & vbnewline & vbnewline) .  Add it to an array. You will have an array of every hand played in that HH file to parse any info you need after each hand completes. You could also use lastindexof for the latest completed hand.

 

 


Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick 'Martin Carter – psxpoker.com Dim dir As String dir = System.Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) 'this is the pokerstars default directory Dim MyHHpath As String = dir & "\PokerStars\HandHistory\" 'create the array to put all the directories in to search for HH files.
Dim DirList As New ArrayList 'get the subdirectories If (System.IO.Directory.Exists(dir & "\PokerStars\HandHistory")) Then GetDirectories(MyHHpath, DirList) 'this is a folder i also save HH files in DirList.Add(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments).ToString & "\HH") lstDirFile.Items.Clear() For Each x In DirList Dim files() As System.IO.FileInfo Dim dirinfo As New System.IO.DirectoryInfo(x.ToString) files = dirinfo.GetFiles("HH*Hold'em*.txt", IO.SearchOption.AllDirectories) For Each file In files 'skip the holdem omaha mixed games If file.ToString.Contains("Omaha") = True Then GoTo skipOmahaFile 'path and filename Dim FileN As String = dirinfo.ToString & "\" & file.ToString Dim filex As New FileInfo(FileN) sizeInBytes2 = filex.Length 'i use this to only add files modified today (ext.letfof is a function... ext.leftof("blah","ah") returns "bl" Dim Lastwrite As Date = eXt.LeftOf(filex.LastWriteTime, " ") 'add the size in bytes and filename to list a If Lastwrite = eXt.LeftOf(Now, " ") Then lstDirFile.Items.Add(sizeInBytes2.ToString & ", " & FileN) End If SkipOmahaFile: Next Next If lstDirFile.Items.Count = 0 Then Exit Sub Else ' populate list b from list a if its empty If lstDirFile2.Items.Count = 0 Then For i = 0 To lstDirFile.Items.Count - 1 lstDirFile2.Items.Add(lstDirFile.Items.Item(i)) Next Else 'start compare and refresh list here 'loop thru list a For i = 0 To lstDirFile.Items.Count - 1 'loop thru list b For x = 0 To lstDirFile2.Items.Count - 1 'If the 2 filenames are the same If eXt.RightOf(lstDirFile.Items.Item(i), ", ") = eXt.RightOf(lstDirFile2.Items.Item(x), ", ") Then 'if the sizes dont match then a hand has just completed If eXt.LeftOf(lstDirFile.Items.Item(i), ", ") <> eXt.LeftOf(lstDirFile2.Items.Item(x), ", ") Then 'here is the file that changed and it is read into memory Dim sr As New IO.StreamReader(eXt.RightOf(lstDirFile.Items(i), ", ").ToString) Dim Sr2 As String = sr.ReadToEnd 'your event would go here

I collect 77 different data values from 9 players per hand and store that data on a list of 7000+ players. I parse about 2300 hands per minute on a laptop with this code. Don’t forget to handle exceptions.

    A fascinating discussion is definitely worth comment. I believe that you should create much more about this topic, it might not be a taboo matter but usually people don’t speak about these issues. Towards the next! Very best wishes!!
