limit in treeview item?

3 posts in this topic

hi

im am inserting items into the treeview but i am stuck at exactly 4088 items

is there another way to increase the limit here??

tnx

$TreeView1 = GUICtrlCreateTreeView($leftMargin, $topMargin, $leftVSplit - $leftMargin, $topHSplit - $topMargin, BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS), $WS_EX_CLIENTEDGE)

; all sorted tracks now..
    For $i = 1 To $numtracks
        $data = StringSplit($itunes_ALLTRACK[$i], '|')
        $artist = $data[1];
        
        If $artist <> $oldartist Then

            $anz = $anz + 1 

            $atvItem[$i] = GUICtrlCreateTreeViewItem($anz & " " & $artist, $TreeView1) ;        
                                EndIf
        $oldartist = $artist
    Next

There is limit 4096 window controls in AutoIt GUI.

By the GUICtrlCreateTreeViewItem() is created window control for that treeview item.

This limit can be overcome by using WIN API TVM_INSERTITEM instead of using GUICtrlCreateTreeViewItem()

but for this you need to know little more about DllStructCreate() and such.

Search forum for examples and look at Auto3Lib from PaulIA.

hi thanks a lot

this is working now with pauls UDF !

Func AddNodes()
    $max = 1000;
    $max_n = 10000;

    ReDim $hNode[$max + 1]
    ReDim $subNode[$max_n + 1]

    _TreeView_BeginUpdate($hTree) ; no update 

    $max_n =1;

    For $i = 1 To $max
        $hNode[$i] = _TreeView_Add ($hTree, 0, $i)
          $subNode[$max_n] = _TreeView_AddChild($hTree, $hNode[$i], "Sub node " & $max_n)
            $max_n = $max_n +1;
          $subNode[$max_n] = _TreeView_AddChild($hTree, $hNode[$i], "Sub node " & $max_n)
            $max_n = $max_n +1;
          $subNode[$max_n] = _TreeView_AddChild($hTree, $hNode[$i], "Sub node " & $max_n)
            $max_n = $max_n +1;
    Next
    _TreeView_EndUpdate($hTree); do update  again .

    
EndFunc   ;==>AddNodes
