TreeView color file and belonging tree

[xtcislove]

Hello,

i stuck again,

Im using this function to create a treeview from root dir.

#include <File.au3>
#include <WindowsConstants.au3>

Global $sPath = @ScriptDir
Global $hGui = GUICreate('TreeView-Example', 400, 600)
Global $idTreeView = GUICtrlCreateTreeView(10, 10, 380, 580, Default, $WS_EX_CLIENTEDGE)
GUISetState()
_CreatePath($sPath, $idTreeView)
Do
Until GUIGetMsg() = -3

Func _CreatePath($sPath, $idParent)
    Local $aFolder, $aFiles, $idItem
    If StringRight($sPath, 1) <> '\' Then $sPath &= '\'
    $aFolder = _FileListToArray($sPath, '*', $FLTA_FOLDERS)
    If Not @error Then
        For $i = 1 To $aFolder[0]
            $idItem = GUICtrlCreateTreeViewItem($aFolder[$i], $idParent)
            _CreatePath($sPath & $aFolder[$i], $idItem)
        Next
    EndIf
    $aFiles = _FileListToArray($sPath, '*', $FLTA_FILES)
    If @error Then Return
    For $i = 1 To $aFiles[0]
        $idItem = GUICtrlCreateTreeViewItem($aFiles[$i], $idParent)
    Next
EndFunc

Folder Structure:

Folder1

Folder2

Folder3

If a file exists in multiple folders, i like to color it red, if not green. 

I know how to do this for files, but nut for the folders.

Because if there is only 1 file in Folder2 that is also in Folder1 that it should only color this single file red, inlcuding its whole tree.

The Folder1 and Folder2 should be red in this case, too. Other files and trees should stay green.

 

Edit:
Basically i like to color a file and its belonging tree red if the file exists more than 1 time.

The color change for file and folders is the same, just use GUICtrlSetBkColor. Here the script a little enhanced:

it's only demostration (playing). If you want to know how to build the logic, than i must ask:

What's a duplicate file?

• Same name
• Same size
• Same hash

Files with same name and size can be different, files with same hash most are real duplicates.

So i suggest try following example(s) in help:

• _GUICtrlListView_SetItemParam
• _Crypt_HashFile 

these will help to build a stable logic.

@AutoBert

I like to check only by name. 
The path structures and filenames are unique. 

If a file is in Folder 1 and Folder 2 its in the same sub directorys.

Folder structure: (Edit: Colored for desired result)

So i am able to check if a file is in more than one folder and color it red instead of green, but i dont know how to paint the sub directorys red, it is in.

My function for finding duplicated files: 

Func _FindDuplicates($sPath)
    Local $aFolder, $aFiles, $aFind, $aRet
    $aFolder = _FileListToArrayRec($sPath, "*", 1, 1, 0, 1)
    $aFiles = _FileListToArrayRec($sPath, "*", 1, 1, 0, 0)
    For $i = 1 To $aFiles[0]
        $aFind = _ArrayFindAll($aFiles, $aFiles[$i])
        If UBound($aFind) <> 1 Then $aRet &= $aFolder[$i] & "|"
    Next
    $aRet = StringSplit(StringTrimRight($aRet, 1), "|")
    Return $aRet
EndFunc

This will return all "trees" that need to be colored red.

 

I could loop trough each line of this array and split each line by "\" but that would also color the characters folder red in Folder_3, too.

I was thinking of using GUICtrlCreateDummy() or to handle each TreeView Item in a array and if the file is a duplicate i could loop trough GUICtrlCreateDummy() or the array, but that wouldnt work either, since the CreatePath function, loops torugh each folder and not the whole tree.

So i found out how to build an array from every folder/file with its Handle:

But i dont know how to use it and the structure is not quiet right.

Have you made it work? It's not impossible.

This is a way it can be done. The treeview is created with your code from a previous post. A dictionary object is used to find file duplicates. In case of duplicates, ItemParam is set to the value 1 all way up through the treeview. In custom draw code, items with ItemParam = 1 are drawn with red background color. Otherwise green.

The zip-file contains the code and a simpel file/folder structure to test it.
