How can you tweak the GETEXPR function?

How or Can you alter the VFP GETEXPR()?

I need to make some small changes and am trying to avoid reinventing the expression builder.

 

[darrellblackhawk]

There are a few tweaks available.

Look up GETEXPR, _getexpr,
Expression Builder Dialog Box, and
Expression Builder Options Dialog Box in the help.

You can write your own and point the VFP system variable _GETEXPR to it.

i.e.

_getexpr = "YourExpressionBuilderProgram"

YourExpressionBuilderProgram.prg, app

... Code, Code, Code.

-Or-

Write a wrapper class/prg that has global scope
and is invoked by some slightly different syntax
such as - MyExprBuild(arguments).
After it pre-processes you're info, it could invoke the default builder.
(this presumes the system variable is left blank)


I started writing one a while ago and never finished.
I took as a basis the standard one and went from there.
I just stopped because I wrote so many other tools that
is became unnecessary.

Have fun!
