Create A TreeView With Only Folders That Include Specific Files?

[buymeapc]

Hey all,

So, I've been wracking my head against what seems to be a very simple thing, but I just can't get the desired outcome here. I'm trying to get a list of a specific file type (*.config) and display the files in a treeview where you can drill down through the folders in the treeview to the files. Below is an example from the forums (from spudw2k) that gives me almost what I want, but I don't want to display the empty folders - that's where I'm stuck.

How can I display the treeview structure without including the folders that contain any of the specified file type??

Thanks for your help.

#Include <File.au3>

$winX = @DesktopWidth * .35
$winY = @DesktopHeight * .375
$gui = GUICreate("File Browser", $winX, $winY, -1, -1, $WS_SIZEBOX)
$tree = GUICtrlCreateTreeView(0, 0, $winX * .9965, $winY * .91125)
GUICtrlSetFont(-1, $winX * .0275)

GUICtrlSetColor($tree, 0x00FF00)
GUICtrlSetBkColor($tree, 0x000000)
GUISetState(@SW_SHOW)

$root = _GUICtrlTreeView_AddChild($tree, "", "MainFolder")
_SearchFolder("C:\Users\test\Desktop\FolderWithConfigFiles", $root)

While 1
    $msg = GUIGetMsg()
    If $msg= -3 Then ExitLoop
WEnd

Func _SearchFolder($folder, $parent)
    $files = _FileListToArray($folder,"web.config", $FLTAR_FILES)
    $folders = _FileListToArray($folder,"*", $FLTAR_FOLDERS)
    _FolderFunc($folders, $folder, $parent)
    _FileFunc($files, $parent)
EndFunc

Func _FileFunc($files, $parent)
    For $i = 1 To UBound($files)-1
        _GUICtrlTreeView_AddChild($tree, $parent, $files[$i])
    Next
EndFunc

Func _FolderFunc($folders, $parentdir, $parent)
    For $i = 1 To UBound($folders)-1
        $parentitem = _GUICtrlTreeView_AddChild($tree, $parent, $folders[$i])
        _SearchFolder($parentdir & "\" & $folders[$i], $parentitem)
    Next   
EndFunc

buymeapc,

I came across the same problem when writing my ChooseFileFolder UDF. If you want to remove the empty folders from the list of those to display, you need to expand the whole tree first to determine which are empty - this can be very, very slow for large trees. When I was asked to incorporate this feature in the UDF you can follow the very similar discussion here:

https://www.autoitscript.com/forum/topic/125293-choosefilefolder-bugfix-version-11-jun-15/?do=findComment&comment=1266806

So I would suggest leaving things as they are.

Hmm...that's unfortunate. Do you think there might be any way to do it by using _FileListToArrayRec to get a list of files and create the treeview items that way?

buymeapc,

Of course, that is what I did in the first versions of the UDF. But that still entails reading the whole tree to determine which folders have the required content, so it is pretty slow for large trees.
