I'm troubled.
Code:

Code: Select all

Public Sub FindDirs(SearchPath As String)
  Dim AllDirectorys As Strings = Dir.FindFile(SearchPath & "/", "*", "System;Hidden;AllDirs")
  For Each Directory As String in AllDirectorys
    If Dir.IsDir(Directory) = True Then
      ListBox1.Append(Directory)
      DoEvents()
      SourceDirLab.Caption = Str(ListBox1.Length())
      DoEvents()     
      FindNextDirs(Directory)
    End If
  Next
End Sub

Public Sub FindNextDirs(SearchPath As String)
  Dim AllDirectorys As Strings = Dir.RecursiveFindFile(SearchPath & "/", "*", "System;Hidden;AllDirs") 
 
  For Each Directory As String in AllDirectorys
    If Dir.IsDir(Directory) = True Then
      ListBox1.Append(Directory)
      DoEvents()
      SourceDirLab.Caption = Str(ListBox1.Length())
      DoEvents()
    End If
  Next
End Sub


Calling it,

Code: Select all

FindDirs("C:/Windows")

9 out of 10 runs KBasic will report,

Deleting the Cache does not help.
In my opinion it works or it doesn't, but not sometime it does and sometime it doesn't

Hhmmmm...

Created a new project, and copied your code. Changed the FormName to fit.

It works every time as expected, 745 entries in the ListBox...

Code: Select all

'Sub Form_OnOpen()
'  ListBox1.RemoveAll
'  FindDirs("C:/Windows")
'End Sub
'

Public Sub FindDirs(SearchPath As String)
  Dim AllDirectorys As Strings = Dir.FindFile(SearchPath & "/", "*", "System;Hidden;AllDirs")
  For Each Directory As String in AllDirectorys
    If Dir.IsDir(Directory) = True Then
      ListBox1.Append(Directory)
      DoEvents()
      frmMain.Caption = Str(ListBox1.Length())
      DoEvents()     
      FindNextDirs(Directory)
    End If
  Next
End Sub

Public Sub FindNextDirs(SearchPath As String)
  Dim AllDirectorys As Strings = Dir.RecursiveFindFile(SearchPath & "/", "*", "System;Hidden;AllDirs") 
 
  For Each Directory As String in AllDirectorys
    If Dir.IsDir(Directory) = True Then
      ListBox1.Append(Directory)
      DoEvents()
      frmMain.Caption = Str(ListBox1.Length())
      DoEvents()
    End If
  Next
End Sub


Private Sub CommandButton1_OnEvent()
  ListBox1.RemoveAll
  FindDirs("C:/Windows")
  frmMain.Caption = Str(ListBox1.Length()) & "   DONE!"
End Sub

It's frustrating me.
Certainly because it's code i have used in the past and it worked without problems.
I have started a few day's ago and the problems started, stripped all the code till the code i listed
and keep the same problems.
I have directory's with more than 20k entry's and one moment it runs fine and the second try bingo again KBasic unknow exception.
Take a much smaller directory and the same problem.
When ported the code to Q7Basic i can easily use FindDirs("C:/") it runs without problems every time.
Use the latest version of KB (5 okt 2010).
i'm out of options.

Because i was out of options i did install a fresh copy of Windows XP.
sadly no luck, it seems that at the first glance it solved my problems but when reading a somewhat bigger directory
i got the same error.

Thinking loud...

Could it be somthing with VBox, as I understand it youre running XP in a VM....

My kbrun.exe is dated 2010-10-21

You could have a valid point Henning,

I don't have Windows hardware anymore started in 2006 with the mac.
But do have older realeses of Virtualbox, will try and let you know.

Did try some older releases of VB but still no luck.
I'll let it rest.

I didn't let it rest, tried it on Windows 7
I now have reclaimed 25 GB
The first 300 directory's where no problem but after the aprox. 300 directory's
the directory's where read in by 1 in each 3 or 4 minutes
Now i'll let it rest.

How much RAM have you allocated for XP in the VM?

745 entries in my app in < 5 sec.

/Henning

In VB i have 2GB allocated for XP.
The speed isn't a problem with XP that problem i encountered with Windows 7 (64 bit)
If it's not crashing i can read 40K directory's in 11 seconds
I'm now testing nearly the same code in Q7B, so far no crashing.
