I didn't think of it until just now, but I guess I could check whether thisform.dataenvironment is an object. I'm still open to other ideas or any flaws with the solution I just proposed.

>Does anyone know of a way to ascertain in code whether a form is currently in design-mode or is being run inside the VFP IDE? For clarification, I'm not talking about using _vfp.startmode or the Version() function.

Is there anyway to know programmatically the difference between those two states (design vs run). I'm thinking that perhaps there is some system variable that is defined/not defined, some property of _vfp/_screen that could be checked, some object that exists in memory during one state and not the other, a Sys() function that could be called, some code that could be run that would throw an error in one scenario but not the other, etc. Any ideas would be greatly appreciated. Thank you.
