Hi Jacky,
You can make a property of a step uneditable by changing the property
flags for the step. First, you want to be able to view the hidden
properties so that you can change the flags for these properties as
well. You do this by going to Configure>>Station Options
and selecting the Preferences tab. Check the box for Show Hidden
Properties. Once you have done this you can select the step type
from the types palette. In the window to the left, you can expand
the tree for the type to see all the properties of that step.
Right click on the property that you do not want users to be able to
edit, select Properties. Then click the Advanced button.
Here you will see a list of the setable flags. Check the box for
PropFlag_NonEditable. You can then do this for all the properties
of the step that you do not want users to edit.
Thanks,
