Print Server & Printer with now duplicate Servers

[Ghost21]

I'm trying to list out in a treeview Print Servers and Printers without haveing duplicate servers listed..

So far this way seems to work

$hItem = _GUICtrlTreeView_FindItem($TreeView2, $PrintServer, True, 0)
                If $hItem = "" Then
                    $Printserver_TreeViewItem = GUICtrlCreateTreeViewItem($PrintServer, $TreeView2) ; Never found server then add..
                    $Printer_TreeViewItem = GUICtrlCreateTreeViewItem($printer, $Printserver_TreeViewItem)
                    If $IP <> "" Then
                        $IP_TreeViewItem = GUICtrlCreateTreeViewItem("IP: " & $IP, $Printer_TreeViewItem)
                    Else
                    EndIf
                Else
                    $Printer_TreeViewItem = GUICtrlCreateTreeViewItem($printer, $Printserver_TreeViewItem)
                    If $IP <> "" Then
                        $IP_TreeViewItem = GUICtrlCreateTreeViewItem("IP: " & $IP, $Printer_TreeViewItem)
                    Else
                    EndIf
                EndIf

But I find it slow when I'm loading 200 or more printers.. How can I speed this up ??

Try this:

_GUICtrlTreeView_BeginUpdate($TreeView2)

; ... make all your updates

_GUICtrlTreeView_EndUpdate($TreeView2)

Try this:

_GUICtrlTreeView_BeginUpdate($TreeView2)

; ... make all your updates

_GUICtrlTreeView_EndUpdate($TreeView2)

Whats that do for it ?

Every time you change something in the TreeView control, it takes the time to redraw the control. This causes the treeview to stop repainting until you are done changing things. See help file.

Ok but for the code above is that the most efficient way of displaying data ?

It would also help if you created the complete list in an array or a delimited string, then loaded the items in the TreeView in one pass without the test for duplication in the loop. De-dup and sort the list in memory away from the GUI before you load the data to the control.
