Description

The command hmCal_Add Relation creates a new relation between two appointments. You must set your own unique reference number into the parameter reference. You must pass the appointment references into the parameters from and to. The parameter type defines one of four releation types:

1 = end to begin
2 = begin to begin
3 = end to end
4 = begin to end

Read more about relationtypes in chapter Relations.
You can also use predefined Constants:

hmCal_rel_EndToBegin           1
hmCal_rel_BeginToBegin         2
hmCal_rel_EndToEnd             3
hmCal_rel_BeginToEnd           4

Releations are only visible in the project view.
