I apologize in advance if this is already covered, but I'm having issues with trying to hook into the _SCREEN.Resize() event via the instructions given in the help file. It's basically a DEFINE CLASS command that has a property assigned to _SCREEN (let's call that property "ioScreen"), and a method assigned to ioScreen.Resize() to resize my form along with the ioScreen object. The problem is, when I try to create an object based upon that class, it tells me "Unknown member IOSCREEN." The example given states 7.0, and I'm wondering if there's something unique about 8.0 SP1 that doesn't allow that assignment, or am I possibly doing something wrong? Thanks in advance.
