Hi
I was wondering if there is a specification of the binary
.TAB/.OBJ/.MAP/etc... files, much like ESRI has an official Shapefile
Specification ?
I guess I could settle and use the MID/MIF format, but reading and
parsing strings is way slower than reading binary.
Best regards
/Morten
Hej Morten,
Not of the binary TAB format. Take a look at Uffes description of the
DAT file: http://www.routeware.dk/download.php under various.
You also have a cracked access to the format with MITAB, I've made
several read and write tab applications with the MITAB library.

Hi
I recently had access to a tabbed shape file with the components
listed below, which failed to open. A message of Unknown error
appeared and then a browser came up. I tracked this down to the fact
that the folder the table was in was readonly (it could have been on a
CD or URL).

Hi Uffe
Thanks that is great stuff! I'll look into it. All I need is to read the shape

already have a nice object model to stuff it into, as well as my own spatial
indexes.
I'd rather not use the MITAB library. I'm going for having my map-render

Dear List,
I have a dialog with a radio button and an OK button - the dialog asks
the user if they want to tidy up the labels on a map before saving the
image as a jpeg, Yes? Or No?
(NB This dialog is within a loop because the code loops through a table
of data creating a map for each row.) If
Hi Tony
In MapInfo 8.0, if you open up a native SHP file, MapInfo prompts you
for a folder for the TAB, MAP and ID file. Therefore these can then be
in a seperate folder to the SHP file. They are built on the fly each
time you open the TABBED SHP.
Your example of a TAB file seems to be missing a

I agree that I can open a .shp file and be prompted to locate the
folder to dump the MI components into.
However it loses all the symbology data and appears in black and
white.
The TAB file that came with the data contains in the metadata
Is there any solution to recover data from mapinof temporary files.
there is no option from mapinfo, if your machine craches and the temporary

Actually Mapinfo should have this option. becouse he knows the structure , so
can update the data back

Hi Tony
Sorry if I have the wrong end of the stick but I think MapInfo does do
what you need now.
The knack is to separate the TAB away from the SHP. Say you want your
SHP files to be accessed from drive f ( ie READONLY ).
Then copy just the TAB files to say c:\SHPFiles\ ( which would be

Hi Tony,
I still believe this is a bug in MI ...
It may be a WAD and an irritating implementation, but unless MapInfo has
promised otherwise it cannot be a bug. Shape file support is after all
not a primary concern - yet.
However, I do support your claim for a different implementation

Hi All!
No, Morten, I would advise against that. A workspace with 1000 layers is
not lightly tampered with.
Especially if thematic mapping is involved. Remember that a workspace file
keeps numbers, not names for each layer, and uses the layer number for the
shade (thematic mapping) command.

It's one of those wish I had another programmer looking over my

An approximate but fast method might be (havent tried it):
1.. Determine principal axes of region. (fast to calculate in c)
2.. Rotate region to align PA with X-Y axes.
3.. Determine MBR of rotated region.
4.. Rotate MBR back to original location.
This will work well on shapes with clear
A twist on this question.
Is there a way of calculating the maximum internal rectangle?
That is, the largest rectangle (of any angle) that fits inside a polygon.
Such a thing would be useful as a text box for labelling.

The max. radius contained circle can be found. Its centre is the visual
