thank you for your help about double-click.
now I've another question about SearchPoint() function.
When I click around a dot object in a map window and use SearchPoint function
to locate the dot object, I found that its search area is very small . Only
when I click right in the dot object's center area , can the dot object be
found. If I clicked a little away from its center, then SearchPoint can't
find it.
My question is how can I enlarge the search area of SearchPoint() function or
are there any other functions can do the same job ?
thanks.
Edward
