MI Help!! Why do I get a .MBO file?

[Stephen R. Riese]

Greetings,
And just when I thought I was getting the hang of MB/MI.  When I compile my
code, MB now compiles it as a .MBO file.  I don't know why it does that --
it was compiling fine (i.e., .MBX) before.  Then, all of a sudden, it
starts compiling as .MBO.  And, of course .MBO files don't run by
themselves in MI.  Is there something I entered in the code that makes do
this?  I've tried Save As, renaming the file, cutting and pasting into a
new file, but it always comes out as .MBO.  My other files still compile as
.MBX. The help files and users manuals (both MI and MB, version 5.0) aren't
helpful.
Please help me get the .MBX files back.
Thanks,
Steve Riese

MI Alias Variables in Map and Create Statements

[Stephen R. Riese]

Greetings,
Thanks to help from this list, I was able to tackle the Alias variable and
use it in calling routines for multiple tables.  Here's a bit of a twist. 
I'd like to do the same thing with the Map and Create Table commands.. For
example, instead of:

Map From Grid Table1, Table2, ..., TableN
and
Create Table table_name(Var1 Type1, Var2 Type2, ..., VarN TypeN)

I'd like to do something like this:

strTable_List = ""
For i = 1 To N 
strTable_List = strTable_List +  ", " + table_name_array(i)
Next i

and then use this string to open tables using the Map command.  Then use a
similar set-up to create tables.  The situation I have is a variable number
of tables to open and generally one column is needed in the created table
for each opened table.  It seems I *should* be able to do something like
this, but these commands won't take alias variables (as far as I can tell,
anyway).
Thanks!

Thanks to all who replied regarding my problem formatting the table columns.
What ended up working was this suggestion from Scott Hall:

MI Area code/exchange ---> 3 digit ZIP

[Joshua Ostroff]

A client needs to append 3-digit ZIPs in the US to phone numbers (area code
+ local exchange).  For example, the phone number 212-896- is within
ZIP 100xx.

In some cases phone area codes and exchanges may cross 3-digit ZIP boundaries.

Short of licensing a $7500 telephone area code/exchange database, for a
six-week project, are there services that can process this job in weekly
batches?

I do have a source that provides reverse phone number appends, but I'm
interested to find an alternative, since that solution would provide both
more information than I need (full address as opposed to just 3 digit ZIP)
but with only about 70% match rate.

Thanks for any suggestions,

Hi Nathalie,

You must certainly have a table with a Character type column (for the 9
digits) and the other one with an integer type (or any numeric type)

You can perform a Table -> Table Maintenance -> Table Structure operation
where you should change the type of your column (e.g. Character type instead
of Integer or whatever it is)

Before you do that, you'd better back up your table (just in case!)

Good luck!

Is there a way to combine these two SQL queries into one, so that I don't
have to save the results of the first query as a table before performing the

(non-mappable data about the points) and Basin_Block_1 (single region
object).

Query 1: Select * from Wells, Basin_Block_1 where Wells.obj intersects
Basin_Block_1.obj into BasinBlock1_Wells.

Query 2: Select * from Wells, Water_Levels where
Wells.State_No=Water_Levels.State_No and Month(Wells.Date)= Any(3,4,5) and
Year(Wells.Date)=1995

MI imagery additional info

[Fran Peck]

Thanks for the response, George and John. MI won't open the image in either
raster or running georeg.mbx - I had already tried that. When I just try to
open as a raster, I get "Raster engine unable to recognize image file
format". When I try to open using georeg.mbx, I get "Specified file does not
contain valid registration information." The vendor that distributed these
yesterday at the meeting I attended said because they are 11 bit, in ArcView
they would have to be viewed with ArcView Image Extension, but I don't know
what I would need with MI.  Will keep trying.

MI FW: Selecting Polylines WIthin Polygons (SUM)

[Stokes Jonathan]

Hi All
as i promised that sum (i'm bored with registering raster images now)
Only one of the answers appeared to work (and that not completely - i'm
still tinkering. Many Thanks to Russell Lawley.

Anyway  here is the original Question

And the Answwer

save a copy of your polygon table and then turn all thos polygons into
polylines (i'm calling this table "edges").
now pack the  table with the two types of line (polylinetab), add a
new column and then update it with rowid so that each of your lines
has an identifier (say LINEID).

now write out the following SQL to the SQL window
SELECT sum(objectlen(overlap(polylinetab.obj,edges.obj) , "m")) 
"RL_TEST" , polylinetab.LINEID
FROM
polylinetab,edges
WHERE
polylinetab.obj INTERSECTS edges.obj
GROUP BY
polylinetab.LINEID

run the query.

this will give you grouped table showing an amount of overlap and a
LINEID for all the polylines that have an overlap, with the EDGES of
your polygons. 
lines that only intersect the edges, not run along them, will have an
overlap of 0m and they will have be grouped together in the row with 
an RL_test = 0

NOW, you have to save that query result as a table . Open it, DELETE
the row that contains an RL_test = 0   (remember, it has grouped all
the lines that do not overlap, into this one record!)

now run a query to select from the polylinetab all thos records whos
lineID is NOT in the query result.

select * from polylinetab where NOT lineid in (select lineid  from
queryX)

Plus,

I forgot to mention, that because it calculates an overlap, if some of
your lines are semi concordant with the edge lines you can also pick
out these by selecting lines with an RL_test (overlap)  greater or
less than a certain value...(but dontforgetthre will be several
lines with rl_test = 0..NOT just the lineid quoted in the resultin
query!)

Dave,

What you want to do is modify your thematic map to change the orientation of
your bar graphs.  This may be done by using that pad of 9 buttons which each
have a red dash and a blue diamond on them.  It is used for both graph and
autolabel orientation.  The diamond refers to your object's point/centroid and
the dash displays the location of the label/graph.

Labels may be moved from that chosen location, however, graphs and pie charts
may not.

Best,
Jo

MI Centroid...

Message text written by "David Eagle"
>How do I change the location of a polygons centroid (probably

Dave,
Not real sure about the bar graphs, but I'd recommend you check to make
sure the centroid is where you think it is.  In at least one case (mine), a
quirk in MI returns the lower left corner of a grid cell as the centroid
(MI 5.0).  This forces me to add half the cell width to the X and Y
coordinated to get the real centroid.  I didn't realize this until I forced
a graphical output (line) that indicated where the reported centroid was.
Good luck,
Steve Riese

PS I'm talking about grids created with the GRIDMAKR program that ships
with MI.

Sum follows:

1)  After you draw the first boundary, you can use the node snap ('S'
key to
turn on and off) to trace the common boundary line when drawing the next
polygon.
Hint: If you want to trace over a big piece of boundary (especially if it's
complicated), click the first point with snap on, hold down CTRL and click
further down the line.  The points in between will be automatically traced.

If you've already drawn the polys and you want to correct them, select the
worst of the two adjoining polys, click the Node Edit button, and drag the
nodes over the good poly so they overlap.  Then select Objects>Set Target.
Select the good poly and pick Objects>Erase.  That will "cut" your bad poly
to exactly match the good one.

2)  Mapinfo has no topology program within it. I am aware that recently
a
topological add-on has been released by mapinfo. Its around $2000 AUD. I
purchased a product called CartaLinx from the IDRISI mob @ Clark Uni for
around
$500 USD. I recall that they have a fully functional demo version on their
www
site. This demo may be enough to do your small job. I wouldn't advise buying
it
except if you plan using it for small jobs. When I loaded one of my datasets
into it, it took "hours" to do a job that ESRIs Data Automation Kit (around
$2000 AUD) took less than a minute to do. I ended up buying DAK as because
cartalinx didn't work on larger datasets. Beware though, DAK is an old DOS
program souped up to work in Windows. It lacks some of the windows
functionality
we've come to be used to, but if you're really only wanting to CLEAN & BUILD
topology, its a real winner.


3)  There are a number of ways that you can create polygons so that you
do not
have this problem. 

Method one is to have snap switched on if you are heads up digitising
existing polygons. To set snap tolerance  Options / Preferences / Map
Window. This is a bit laborious if you have more than a few polygons to
create.

The next method is to copy the line nodes from the layer with the existing
polygon boundaries on to your new layer. To do this, ensure the layer with
the polygons or boundary lines to copy, is set to editable. Select a polygon
or polyline, select reshape button, then use shift click or alt click to
select the nodes you require.  Hit Ctrl  C (copy) then go to layer control
make your new layer editable. Hit Ctrl V (paste). Continue to do this until
you have created your new schools boundary based on the original table
polygons.

Method three; If you are creating your school boundaries from scratch you
can create the first polygon then each additional is purposely created to
overlap the first polygon. Then you use Objects / Set Target / Erase or
Split.

You will probably find that you will need to use a combination of all three
of the above to achieve the result you want.


Thanks to all.  I am still working on it to figure out the "best" way to
deal with the issue.

MI Splitting Polylines

[Stokes Jonathan]

Afternoon All (depends on your spatial location obviously)

I've just done a split operation in MI 4.5.2 but some of the lines have
remained 'joined.' that is they are the polyline equivalent of complex
regions (where you have multiple polys for one record in the attribute
table). i need to split these up completely as i have to have one line in
the table for each spatial object. i could port the whole lot into ArcInfo
(PC version via e00) and then back again which would sort it but it seem
like a load of hassle

any ideas ?

TIA and will sum (damn i haven't done the last one - expect it about 5.00pm
when i am really desperate to go home).

Jon.

MI Centroid...

[David Eagle]

Ladies and Gentlemen, I have a no doubt simple question for you...

How do I change the location of a polygons centroid (probably 
defeats the idea of it being a centroid!) More specifically I have 
thematically created some bar graphs which once generated are 
not where I wish them to be. Anyone know how I can drag them 
into the right place?

TIA
Dave

Subject: Re: MI MapX - can mapx import mif/MID files

[JOHN-MCCARTHY]

I think there exist a problem within how MapX creates 
tables using the createlayer method. Since the new table 
has a single field and only a single field 'geoname'it 
is not possible to create a table with multiple columns 
of data. So the importation of a MID/MIF would be 
limited to the first column of data and the object 
associated with it. With that being said, the only way 
to actually import or populate a table from a MID / MIF 
would be to have a skeleton table with no data, the 
correct columns already created, then just import only 
the objects and fill in the fields with the associated 
data bound to the object. The problem with this is you 
need to create the initial table with mapinfo. All 
sounds kind of dumb doesn't it. If anyone has found a 
different way of doing this in MapX I'd be interested in 
hearing it, and also might volunteer some of my time on 
such a project since I have most of the other code 
aready written.

Re: MI MapX - can mapx import mif/MID files

[Bill_Wemple]

There already is a MIF Import sample application on the MapX website.  Log
on to www.mapx.com, go to download section for MapX, then access the
testdrive center to get at the sample applications.  Its toward the bottom
of the list for samples in Visual Basic.  Please follow the readme closely.
It may need a little tweaking, but it should get you on your way.

RE: MI Remove spaces from text

[Ian . Straus]

You might export them to MS-Access, and use the Trim$ function to take
the blanks off both ends.  Better yet, redo it all with Access, with
several Trim$ in the statement, and get rid of your interior extra
blanks.
Yes, concatenate is the right word.

MI MapInfo Pro & Oracle 8i Spatial

[Chris Clarke]

I was wondering if anybody has had any experience of retaining the symbology
of MapInfo tables that have been uploaded into Oracle 8i Spatial. I
understand that 8i only stores one set of symbology per table but wondered
if anyboby had a clever way of doing it ie. extracting the symbology to a
lookup table in 8i and reapplying it when the data is accessed with MapInfo
Pro. Thematically mapping it by attributes when it is loaded is not an
option, we have several thousand TAB files, mainly geology, that have
intricate colour schemes.

Any thoughts would be appreciated.

Regards

Chris

MI Using Encrypted Files in MapX - or storing MAP files in a different dir to TAB file.

[carl . nunn]

I am writing an application using MapX which requires the map data files to
be encrypted (for copy protection).

Does anyone know of a means to do this?

I am currently investigating using C-Dilla but this may not work correctly
with an OCX.

Alternatively, does anyone know of a means in MapInfo/Mapx to store the .MAP
in a different directory to the .TAB file?

Thanks

MI Problem with MapX 4

[Rohit Goel]

Hi,
Can someone help me with this strange 
problem.
I created a dll using Mapx 4 in Visual Basic. When 
I
access the dll from another Vb project, it runs 
fine. But
when I access it from an ASP file running in 
Internet Explorer
it says that Mapx40.ocx or one of its dependencies 
is not correctly
registered. The user manual says that I might have 
to pass the license
string while creating a Mapx object. How do i pass 
it from the Vbscript
code in the asp file, if that is necessary. 

Thanks
Rohit
