some time back, i created a visual foxpro application containing a tree control (activeX) that requires file comctl32.ocx to be in the windows\system directory. no problem. later i installed visual basic. the same file existed with basic and overwrote foxpros comctl32.ocx file. my foxpro app no longer worked properly. i had to copy foxpros own comctl32.ocx file back. if i had written an app in both foxpro and basic that ended up on the same computer, how could this conflict been resolved?
