please help, this is bugging me to death.
i cannot seem to get mapinfo to give me the X/Y coordinates of a selected
object with any reasonable level of accuracy.
i use the following code from VB:
MyAccessObject.X = MIobj.eval ("objectgeography(selection.object,1)")
and it will only give me a float/double to 3 or 4 decimal places. this is
nowhere near good enough.
if you want to test this for yourself, select an object in mapinfo, type
this into the MapBasic window:
print objectgeography(selection.object, 1)
print objectgeography(selection.object, 2)
then create a new point in your table, and set the X and Y to the coodinates
given in the message window. now compare the locations of the original and
the evaluated copy. cool huh?
this is a major problem, as i will be having people updating the X/Y of a
record in my access table based on a selection they have made in MapInfo,
but having this oversimplified rounding error makes stuff anywhere between a
couple of metres to a couple hundred metres WRONG.
there was already a discussion that i participated in involving something
along these lines in early May, but i don't think this side of things was
explored.
basically, how can i get Access to evaluate the current position of a
selected object in mapinfo with as much accuracy as possible?
