In the discussion that follows the code, the errors are pointed out, with some suggestions to correct them. Here is a version with those suggestions incorporated. I can't test it myself because I don't have VB6 any more.

Still the same error I'm afraid ( I know you can't test but really greatful still ) on the same line.
Just doing a Google and here's comments from another forum which may help in the right direction with also having controls on the form !!:
"OK I was playing with this a little more and I can duplicate the error if I place a control on the form that doesn't have a left property. The posted code takes care of the line control but all other controls that don't have a left property are not handled. The main one that would give people problems is the timer control. You should be able to trap that error in the save and resize sub."

On Error GoTo 0
