Jumping scrollbar in ExplorerListGadget

When my program deletes files in a folder, the ExploreListGadget
pointing to that folder gets crazy, showing anymore files and ExploreListGadget scrollbar jumps up and down till last file is deleted.
How can I freeze that window till end of operation?

Try using the #WM_SETREDRAW message on the explorer list before starting the deletion and then use again after finishing.
Just don't forget to invalidate the gadget's client area (InvalidateRect_()) once you reset the redraw flag.
Use :
Code: Select all
SendMessage_(GadgetID(#myList), #WM_SETREDRAW, 0, 0)
before the deletions, and use
Code: Select all
SendMessage_(GadgetID(#myList), #WM_SETREDRAW, 1, 0)
InvalidateRect_(GadgetID(#myList), 0, 1)
afterwards.

Probably due to some latency resulting from deleting the files and the explorer list being updated etc.
Try inserting a largeish delay just before resetting the redraw flag - just as a test like.
