>When people develop an application that uses icons, where do they get the icons that they use?
> Are the ones that come w/vfp re-distributable?
Yes.
> Do people contract out and have them custom-designed?
Yes.
> Are there other sources of re-distributable icons to pick and choose from?
Yes. Search the Web. You should be able to find literally millions of icons you can use.
We also design them in house. You have a tool that came with VFP: IMAGEDIT.EXE you can use to create icons.
