Hi,

I'm running an archiving procedure for a group of sel ected mails.
The selection list needs to be locked during the archiving procedure (which may take a lot time depending on the amount of selected mails).
Is it possible to lock the email selection list (or lock all the outlook application) and prevent user fr om using this list and modifying selection set?

Thanks

Hi Spiros,

How do you create such a list? Or maybe, you talk about items selected in the Outlook Explorer window? If the latter than I assume you cannot modify the selection until the archiving procedure is completed; this is because the procedure is run in the main thread.

Do I understand you right?

I'm getting Selection list from "SelectedItems" of 


class function OutlookUtils.GetExplorerSelectionItem(AExplorer: Explorer;var SelectedItems:SelectedItemsType): IDispatch;
var
  sel: Selection;
  i  : Integer;

begin
  result := nil;
  sel := AExplorer.Selection;
  try
    if (sel.Count > 0) then begin
      result := sel.Item(1);

      setlength(SelectedItems,sel.Count);
      for i := 0 to sel.Count-1 do
        selectedItems[i] := sel.item(i+1);

    end;
  finally
    sel := nil;
  end;
end;


but during the archiving procedure which goes like : 


for mlNo := 0 to length(SelectedItems) - 1 do //selected mails loop
 Begin

   ...archive message   MailItem(SelectedItems[mlNo]) ...
 End;


I can click in outlook explorer window and modify selection.

Oh, I see.

There was another way: you could store selected items to an array and process that array.
