Form control type at run-time

This shows how to get the type of a form control at run-time. The code iterates through the controls in a field group and checks each control for it's type.

    FormControl fc;
    int         i;

    // ...
    for(i=1; i <= FieldGroupName.controlCount(); i++)
        fc = FieldGroupName.controlNum(i);
        if(SysDictClass::is(fc, classNum(FormStringControl)))
            info(strFmt("%1 %2", fc.name(), fc.type()));
If you do this in Dynamics AX 2012 you will get the following warning:

The SysDictClass::is method is obsolete. Use the IS operator instead.

The new syntax is:
if(fc is FormStringControl)

Looks better, don't you think?
