here's what i am doing:
in windows form, open some drawings, just reading, get the layout object id and list them in list view. then i export the list to excel. then i imported the excel text back into windows form, then i can read the list view and grab the drawings and their layouts accordingly. i am stuck on converting the string object id, such as (-4264276) back to object id object. did some research and people try to play with handles. doesn't apply to what i am doing here. so don't even mention handles to me.
i know that the com library can convert object id to object with a string. as the argument. is there something similar in .net.
see attached picture of the windows form.
thank you
Bob
