Short of digging down into the form to check the class that each control was derived from, there are a couple of ways to check. If you have an object and want to know what form it's a part of, as long as the form was an SCX launched by DO FORM, SYS(1271) returns the name and path of the SCX containing the object at runtime.

If you have an object reference, SYS(1272) will give you the containership hierarchy of the object. It won't dig back past the form/formset level.

If you know that, you're set - you know the containership. If you want to start from the top and check to see if the control is present, look at\ using AMEMBERS() and dig down to find it.
