IsMember()
Summary
Tests whether a record is a member of a selection set.
Changes
Added to Version 5.0.
Syntax
answer = IsMember(string set_name, string row_handle)
| Argument | Contents |
|---|---|
| set_name | The selection set to test |
| row_handle | The record handle of the record to test |
Returns
A string, "True" if row_handle is a member of the selection set, otherwise "False".
Example
//Open BDOCUMENTS\CALIPER\\< product name>\TUTORIAL\NElayers.wrkz
tutorial_folder = RunMacro("G30 Tutorial Folder")
wrkz = OpenWorkspace(tutorial_folder + "NElayers.wrkz")set_name = "Selection"
row_handle = "4465"
answer = IsMember(set_name, row_handle)
ShowMessage("It is " + answer + " that the record with the handle " + row_handle +
" is in the " + set_name + " set")
// Create a formula field that indicates which records are in set Selection
If IsMember("Selection", GetRecord() ) then "Selection" else ""Notes
IsMember() returns "False" if row_handle does not exist.
IsMember() can be used in formulas, to do different things for different selection sets.
