Vampie 0 Posted September 27, 2010 (edited) Hi all,I'm using a list view and sometimes there can be like 20.000 lines in the listview.I read files and add them to the listviewIs there a way to delete all the records in 1 go?I've tried to use _GUICtrlListView_DeleteAllItems, but that deletes record by record, so it takes a long time to delete them all. Any ideas?thank you very much. Edited September 27, 2010 by Vampie Share this post Link to post Share on other sites
water 2,387 Posted September 27, 2010 (edited) When you look at the include file you can see that the function handles the delete in two ways depending if you pass a ControlID or a handle to the function. _GUICtrlListView_Create returns a handle whereas GUICtrlCreateListView returns a ControlId. So creating the listview with _GUICtrlListView_Create should make the deletion run faster.

Melba23 3,455 Posted September 27, 2010 Vampie,I've tried to use _GUICtrlListView_DeleteAllItems, but that deletes record by recordIt most certainly does not - it deletes all records at once whenever I use it (which is quite often!). But as water pointed out, you need to use the handle, not the ControlID. So if you have created your ListView with GUICtrlCreateListView you need to use:_GUICtrlListView_DeleteAllItems(GUICtrlGetHandle($hList_View))wakillon's tip is also a good one - why not try it?M23 Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind Open spoiler to see my UDFs: Spoiler ArrayMultiColSort ---- Sort arrays on multiple columnsChooseFileFolder ---- Single and multiple selections from specified path treeview listingDate_Time_Convert -- Easily convert date/time formats, including the language usedExtMsgBox --------- A highly customisable replacement for MsgBoxGUIExtender -------- Extend and retract multiple sections within a GUIGUIFrame ---------- Subdivide GUIs into many adjustable framesGUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView itemsGUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeViewMarquee ----------- Scrolling tickertape GUIsNoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxesNotify ------------- Small notifications on the edge of the displayScrollbars ----------Automatically sized scrollbars with a single commandStringSize ---------- Automatically size controls to fit textToast -------------- Small GUIs which pop out of the notification area Share this post Link to post Share on other sites
