What "error" are you getting ?

The problems I see here is that you have an extra space in "oleExcelObject ", and you need to add Visible = .T. to your OLEControl (or do a THISFORM.Excel.Visible = .T. after your .AddObject) in order to have the Excel sheet show up on you form.

Putting .AddObject in .Init is fine.

Otherwise it should work.

Are you trying to put the DEFINE CLASS in the Form's .Init event ? If that's what you're doing, that's your problem: you have to put a DEFINE CLASS in a separate .PRG file (if you are using an .SCX/VCX based Form) and then add it to the Form using .NewObject which allows you to specify where your class is stored.
