Peter,
First I looked at what is on the MSDN site. It took a little while to figure out what the various documents were saying, but in the end it's extremely easy to do.

1. Build a form with controls related to the properties you want to change on a control.
2. Build a project with a prg set to main that accepts 3 parameters. At this point I don't even use them, but I'm still learning.
3. In that prg, there are several variables created by builder.app, the calling program that give object references to the selected control, container and form. You also might want to put in an ASELOBJ() call for multiselect if needed.
4. With those object references, you can access the control properties.
5. Compile an app and put it in the vfp\wizards dir.
6. USE vfp\wizards\builder.dbf and add an entry using the others as a guide. All you have to add is the control baseclass type, a description and the app name,e.g., MyTextboxBuilder.app WITHOUT a CR/LF. Just type in the name, no {ENTER}. When you rightclick on a form and select builder, you get a list of the builders aimed at the control base class, if more than one exists.

Thats pretty much it. Properties are simple, I'm still working on easy method editing, but I think that will come together today. I looked at BuilderB and BuilderD and decided just to write the things myself. I created builder textbox,combobox and checkbox controls that have a property for the control property and getvalue()/setvalue() methods. Now I just drag these onto a form that has an object reference to the selected control and they just get and set the values as needed.

That's pretty much it. Good luck.
