win32lib suggestion

i used this function to delete all items in treeview:

Void = sendMessage (treeview, TVM_DELETEITEM, 0, TVI_ROOT)

but because of it my program was behaving very strange, and thats why i put
off working on it for quite some time

now i finally found out what was wrong:

i should have used

Void = deleteItem (treeview, -1)

instead.

So: there should be a warning message box when programmer uses
Void = sendMessage (treeview, TVM_DELETEITEM, 0, TVI_ROOT)
or some similar shit which can cause bugs,
at least in debug mode (which i think win32lib should have).

like this:

if msg = TVM_DELETEITEM then
    if lParam = TVI_ROOT then
        message_box ("Warning: using TVM_DELETEITEM and TVI_ROOT can cause
bugs in your program!", "", 0)
    end if
end if
