Can you import MapInfo map "as is" into Smallworld without converting it to
NonEarth map? The problem again is in scale/coordinate system/projection.

from my understanding, there is no such thing as a creation scale of a map
in MI.
you draw your things (in the projection you have choosen) and that's all.

Hi Anirban,
usually we use real (not paper) units in GIS. For GIS scale is accuracy and
detailness - not the size. If we have a raster 1:1 from a 50cm*50cm
paper map we create a digital map with 5km*5km size. Then we can print this
map in 1:1 scale or in any other scale, but we won't have
Thanks,
I will incorporate your suggestion of creating the rectangle object
variable outside the function - might speed things up a tad.
Cheers,

Never mind, I worked it out.
This function checks if any objects from a specified layer are visible
in the current map window - (nothing to do with layer on/off)

ByVal s_Layer as string
)

It is amazing if this compiles at all.
You will either have to use function IntersectNodes() and loop through
all records in s_Layer or sa

All lines ended with Interactive. The problem was in using a mapped drive.

Never use mapped drives in the path :)

Hi Luis,
The problem should have been fixed by now. But you have to save your
workspace with the latest
version of MapInfo, because the fix is made in the workspace save, not in
the workspace load !
You could also make sure that every line in your workspace that begins with

The best query will be

otherwise for specific col type you can use

Select * from where = 0 (for integer) and so on..
