Origin Ver. and Service Release (Select Help-->About Origin): gf3s4-6478-7077916 Operating System: Window's Vista Hi,
I am writing an Origin C program for global fitting. I need to access the worksheet during the fitting. I fount that once you start using user defined function in nlsf, the active layer would be graph. So how to get the worksheet object? wks=Project.ActiveLayer()does not work any more. Thanks.
