I wanted to give you some pointers, but did not claim to give all the
answers. As to issue #4, the number is the sequence number of the icon in
buttons.bmp, starting with the first one in the first row and counting to
the last one in the last row.
Looking at the Notes for WriteArray(), it says "Array elements that are not
numeric or strings are ignored." Since the elements in array coords are
complex variables, you need to change them to numbers or strings. One
solution is below, which writes each coord complex variable as a decimal
lon/lat comma-delimited pair:
dBox "mapextents" title: "Map Extents" toolbox
Tool 1, .5 Icons:"bmp\\buttons.bmp|131", "bmp\\buttons.bmp|165",
"bmp\\buttons.bmp|196" cursor: "Crosshair" do
on escape goto clickskip
on notfound goto clickskip
//capture map views lon/lat bounds
coords = GetScopeCorners(GetMapScope())
//write the map view lon/lat bounds to a text file
ptr = OpenFile("c:\\temp\\testmap.txt", "W")
for i = 1 to coords.length do
WriteLine(ptr, r2s(coords[i].lon/1000000) + "," +
r2s(coords[i].lat/1000000))
end
CloseFile(ptr)
clickskip:
on escape default
on notfound default
endItem
Close do
Return()
endItem
endDbox
