Title: Dynamically delete TListView columns
Question: If you've ever tried to delete a list view column at run time, you
know it can't be done. Or can it?
Answer:
There is an undocumented Delphi function that allows you to just
that.
The command is declared in the CommCtrl.pas unit. Its declaration
is shown here,
function ListView_DeleteColumn(hwnd: HWND; iCol: Integer): Bool;
where hwnd is the handle of your list view component and iCol is
the index of the column you want to delete. Remember, the list
view column index is zero based. Here's an example of calling the
command:
procedure TForm1.Button1Click(Sender: TObject);
begin
ListView_DeleteColumn(MyListView.Handle, 1);
end;
