Well, you can't do what DBase did with codeblocks, but you can get part way there with my public domain CodeBlock VFP program. You could, for example, define a class of buttons that can be added to forms after the fact. Perhaps:

DEFINE CLASS AddableButton AS BUTTON
cClickCodeBlock = NULL
PROCEDURE CLICK
IF VARTYPE( THIS.cClickCodeBlock) = "C"
  = CodeBlock( THIS.cClickCodeBlock)
ENDIF
ENDPROC

Then, even though you can add a method after the fact, this class allows you to add code as a *property*. Requires of course that you have CodeBlock (available here) in your project.
