LBHelpSearchStd_jaba

Edit 0 1 …
This is the standard version of LB Help Search. This version incorporates an index listbox.

A bitmap is used for the help button, but program will substitute a text button if the bitmap is not found in the default directory. You can d/l the bmp file if I did the link thingy correctly.
help1.bmp


Here's the listing:
