>Still. I'd like to look into it a bit, perhaps as a low-end alternative. Can you direct me to any further documentation on how to use HTML input forms with Foxpro? Are we talking about Active Server Pages? (

Nope, basically, you are automating the browser control. The best place I have seen info about this is in Rick Strahls book about using IE for your interface.

A Ha... this is a place you may be able to pick up some major savings. Populating combos and lists is VERY time consuming. You may want to build a pulldown grid control. Basicsally, this control uses a textbox and a button. When the user presses the button you instantiate a grid which actually looks like and is placed in the place where the grid would go. I have seen examples of this in the book 1001 Things you can do with VFP. I think I have also seen it other places. Since the text box doesn't need it's list filled, the more of these you replace, the mosre time you will cut of instatiating this form.

Well, that makes sense. Are you using scrolling forms? IF so, you may want to do away with that and create your own scrolling interface. This may be a bit more light weight than the scrollbar form.
