MI trouble combining complex polygons

[Humphrey, Ben]

I have been attempting to combine complex polygons of telecommunications
coverages using MapInfo 5.5 on a Win NT machine with 128 Mb RAM.  The
results of the combination procedures I have been trying (which usually take
1-2) hours are just a copy of one of the coverages I tried to combine.  The
methods I have been trying are:

Combining from two separate layers-
1.Select the polygon in one layer, set as editable and as a target
2.Select the polygon in the other layer as click Objects>Combine

Combining from one layer-
1.Copy polygons from both coverages to the cosmetic layer
2.Query>Select All from Cosmetic Layer
3.Objects>Combine

To reiterate, the result is not the intended combination, but merely a copy
of one of the two layers i tried to combine.

Any suggestions?

RE: MI Workspace descriptions

[Humphrey, Ben]

Fraser-

I'm not sure how ER mapper appends comments, but at the very least if you
wanted to append comments to your MI workspace you could open up the .WOR
file in a text editor and use the apostrophe character ('), which is used in
MapBasic to signify the beginning of a comment.  Then you can comment to
your hearts content.  Just be sure you add the comments AFTER the initial
workspace information that is preceded by exclamation marks (!)

eg.

!Workspace
!Version 550
!Charset WindowsLatin1

'this is a comment
'you can type all you want to describe your workspace here

Open Table "C:\Mapping\Database\AllSites" As AllSites
etc.etc. etc.

MI creating back buttons with mapbasic

[Humphrey, Ben]

Hello all-

I am currently building a small tool that:

brings up a dialog with a popupmenu containing all open tables
You select your table and press "OK"

Pressing OK calls a subprocedure which brings up another dialog that shows
all column names within that table.

I want to create a "back button" (for the user who hypothetically says
"whoops! I chose the wrong table...) on the second dialog so that it is
removed and the dialog with the popupmenu allows them to choose a different
table.

So far I can call the procedure again which spawns a new window with the
popup dialog, but does not remove the dialog with the column names.  So if I
kept pressing back on the windows that pop up it is essentially a recursive
function

Any ideas?

MI selecting using mapbasic

[Humphrey, Ben]

Howdy all-

Big fustrating thing happening with creating a select statement within
mapbasic:

select * from t_name where GSM_OPERATOR = search_list(k) into array_string

The above works producing a table with the search string contained
in search_list

select * from t_name where c_name = search_list(k) into array_string

In this statement, when c_name is a string from an array containing
GSM_OPERATOR, I end up with an empty table.

Anybody have this experience before?

Re: MI selecting using mapbasic

[Humphrey, Ben]

Hello all, here are the working results from 2 questions I have posted in
recent weeks (in case anyone is interested)

1.  With regards to CREATING BACK BUTTONS, the suggestions provided by
numerous individuals to simply put multiple selection boxes within one
dialog looked very slick and works much better.  Thanks!

2.  Regarding selections within mapbasic, I received two suggestions.  One
was to construct a Run command statement and the other was to use the alias
variable.  I found that using the alias variable for my column names solved
all of my problems.  While I am sure that the Run Command statement is
useful in other applications, mine was specific to using the alias variable.

Cheers to all who helped, because I had just about quit on this one!

MI Overflow error on custom select tool

[Humphrey, Ben]

Howdy-

I am getting an Overflow error withing mapinfo when I use my tool at this
line:

t_name = TableInfo(win_id,TAB_INFO_NAME)

The point is to be able to click anywhere on the active window, have the
event handler select the polygon underneath the layer and then select all
polygons which intersect that polygon.  Suggestions, remedies?

Thanks in advance to the code crackers out there

-Ben

Here's the code:

Include "mapbasic.def"
Include "icons.def"

Declare Sub Main
Declare Sub Neighbor

Sub Main
Alter ButtonPad "Tools"
Add Separator
Add ToolButton
Drawmode DM_CUSTOM_POINT
HelpMsg "Thematically shade all region neighbors"
Calling Neighbor
Icon  MI_ICON_COMMUNICATION_6
Cursor MI_CURSOR_CROSSHAIR
Show 
End Sub

Sub Neighbor

Dim win_id As Integer
Dim  fx, fy As Float
Dim t_name As String

win_id = FrontWindow()
t_name = TableInfo(win_id,TAB_INFO_NAME)
fx = CommandInfo(CMD_INFO_X)
fy = CommandInfo(CMD_INFO_Y)

Select * From t_name
Where obj Contains CreatePoint(fx, fy) into selection

Select * from t_name where obj intersects any (select obj from selection)

End Sub

MI automatic thematic shading

[Humphrey, Ben]

Another message from me, after I solve this one I'll pose the whole
solution, thanks in advance to Yannick Leduc who set me on the right track
RE: my MI Overflow error on custom select tool posting.

I have successfully created a tool which selects all polygons bordering a
polygon selected by the tool.  I want it to shade each polygon with an
individual value.  From what it seems I need to specify a brush setting for
every single polygon by hand so it would be hard to automate using mapbasic.
Anybody have any experience with this?

Here's the line of code I've been working with, if I replace the ? with
"Default" it works (IE no error message), but nothing gets shaded.

Shade window win_id selection with Sector_Name values 

thanks

MI SUM: Overflow error on custom select, automatic thematic shading

[Humphrey, Ben]

Things couldn't have worked better on both of these questions.  Thanks to
all who responded to each, only one person had a suggestion for thematic
shading but it was enough to lead me in the right direction.

Issue #1: OVERFLOW ERRORS

Indeed the problem was that the FrontWindow() command returns a large
integer value that has nothing to do with how many tables are open.  So I
was really just using the wrong numbers.  I was able to circumnavigate this
problem by using the SearchPoint and SearchInfo commands.  The improved code
is listed below:

Sub Neighbor

Dim win_id As Integer
Dim foundobj, objtype, i, j, numlayers, numthemes As SmallInt
Dim  x, y As Float
Dim t_name, cstring, commandstring As String

win_id = FrontWindow()

If WindowInfo(win_id, WIN_INFO_TYPE) <> WIN_MAPPER Then
Note "This tool only works on Map windows."
Exit Sub
End If

x = CommandInfo(CMD_INFO_X) 'x coordinate of users click
y = CommandInfo(CMD_INFO_Y) 'y coordinate of users click

foundobj = SearchPoint(win_id, x, y)

If foundobj = 0 Then
exit sub
End If

t_name = SearchInfo(foundObj, SEARCH_INFO_TABLE)

The select was rather straightforward with an obj within type statement

Issue #2: AUTOMATIC THEMATIC SHADING

This was a little trickier, but since nobody really suggested many things
I'll just paste the code in case anybody is interested.  Per John
Schlosser's suggestion, I used the unique values within one of the table
columns to give the shade command an idea of how to shade the map.  I ran a
for...next loop to create a long string containing all the individual values
in the column and then utilized Run Command to convert the string into a
shade command.

fetch first from neighbors  
cstring =  + neighbors.Sector_name + ""","
for i = 1 to tableinfo(neighbors, TAB_INFO_NROWS)-2
fetch next from neighbors
cstring = cstring +  + Neighbors.Sector_name + ""","
next
fetch next from neighbors
cstring = cstring +  + Neighbors.Sector_name + 

Run Command "Shade window " +win_id+ " selection with Sector_Name values " +
cstring

RE: MI batching register

[Humphrey, Ben]

I agree, I have been having A LOT of difficulty with people submitting maps
with only 3 registration points and have had abysmal results.  They don't
seem to understand when I ask for more.  I would even suggest a minimum of
5.  One for each corner and one smack dab in the middle.  One guy I
mentioned this to submitted a map with 12!  It was a bit of extra work but
it registered like a dream.  Well, at least as dreamy as image registration
can get.

RE: MI Spammer redux

So Far we have:

1.  Paint their backs to start a race war
2.  Automatically filter the list so that only messages from subscribers can
get through
3.  Put them on our mailing list so they get bombarded back.

Are any of these feasible? (point 2 seems the most civil)

RE: MI Mapinfo 5.0 Help file

[Humphrey, Ben]

This is an interesting subject, as I was once vicitmized through the
purchase of a semi-pirated version of Adobe Photoshop.  Adobe stood behind
me all the way which was very kind of them and sent me a free upgrade to the
software I thought I had been purchasing.  Of course this wasn't a copy I
purchased for 9.99 on CDR that came with no documentation, so it really
depends on the awareness of the purchaser about whether they are buying a
pirated version of the software and if that was their intent.  These days
especially with internet sales and bulk price reductions it is harder to
tell what is legit and what is not.  If the intent of the purchaser was in
good faith, then I would have no problem sending them a help file, as it is
not a core component of the program anyhow (although I must say rather
essential).  I suppose if it ends up being a pirated version, that person
who bought the software would have to contact the vendor and work out some
sort of arrangement.  Each company has its own policy regarding issues like
these and it would be interesting to hear what mapInfo's stance is.  So...
I'm listening!

Cool your jets dude.  You may have had an extensive dialog with this guy in
Thailand that puts you in an enlightened position of knowledge with regards
to the legitimacy of this his software, but others of us (maybe we're all
just naive) are a bit more forgiving when software fails.  I can at least
speak personally to the fact that in the company I work for it would be hell
trying to locate the original install disk for MapInfo and it would in fact
be a million times easier if somebody on the MapInfo list just sent me a
copy.  And I GUARANTEE you that my copy was paid for in full.  I'm just
trying to point out that there are alternatives to the story and to flame
everybody with this "my stuff smells sweeter than yours" tirade is pretty
unkind.

MI promoting records

[Humphrey, Ben]

Anybody know of a way to promote records in a mapbasic table?  I want to
select a specific row and move it so that it is the first row in a table.

thanks,

G you know what I mean...

transtlation of my late day garble:

Anybody know of a way to promote records (like you can in arcview in a
mapinfo table using mapbasic (or any other method for that matter.)

sorry for the confusion.  I banged out the message 2 secs before I went

RE: MI Fwd: AV: General--New guidance for using the ArcView list and an important survey question

[Humphrey, Ben]

Everybody keep sending the Friday funnies, it makes me think (jut
for a sec) that I'm not a GIS dork holed up in a cube somewhere in corporate
america.  

As for the rest, I do agree with Steve.  It would be nice to not have
everybody post all their replies publicly and I completely agree with the
idea of the person who asked the question posting a summary of all the
answers they got (its the least they could do for all the help they got!).
I keep all summaries because who knows when I may run across something that
has been discussed, but to have to sift through a billion replies instead of
one concise summary is a pain in the derriere.

Okay, I'm finished, go back to your GISing

RE: MI SUM Joining tables...

[Humphrey, Ben]

Okay try this:

1.  Open the two tables you wish to join in side by side windows in arcview
2.  Select the two common fields in each table with the mouse.
3.  Make sure the table you want the results to be stored in is highlighted
4.  Join the tables

I agree with peter 110%, Joining in Arcview is a *pinch*

RE: MI MapBasic Shade statement

[Humphrey, Ben]

(Okay okay, here you go so everybody can read it! =)


Just to add to the list of suggestions, here's a little snippet of code from
an MBX I wrote to shade a variably sized list of polygons with individual
colors:

Table name is "neighbors", but could be any table that was formed from a
prior selection

fetch first from neighbors  'creates a text string of all sector 
'name values in order to
thematically 
'shade the layer

cstring =  + neighbors.Sector_name + ""","
for i = 1 to tableinfo(neighbors, TAB_INFO_NROWS)-2
fetch next from neighbors
cstring = cstring +  + Neighbors.Sector_name + ""","
next
fetch next from neighbors
cstring = cstring +  + Neighbors.Sector_name + 

Run Command "Shade window " +win_id+ " selection with Sector_Name values " +
cstring 'shades the layer

Hopefully this sheds a little light.  I posted a question to the list about
how to do this and didn't get exactly the answer I was looking for, but it
was enough to point me exactly where I wanted to go.

good luck,
Ben

MI square ends on buffers

[Humphrey, Ben]

Anybody know of an mbx (or anything else for that matter) that lets the user
create buffers around line objects so that they are not rounded at the ends?

I am trying to buffer individual sections of an MI road file and the buffers
overlap eachother at the end and beginning of each segment.

MI returning the directory structure leading to an open table

[Humphrey, Ben]

And a lovely thursday to all you western hemisphere folks (woo hoo its
friday in New Zealand!).  Just a quick one here:

Is there any way in mapbasic to issue a command that returns the directory
structure leading up to an open table?

ie:  

Dim tablocation As String
tablocation = PathToOpenTable$("foobar")  'I made up PathToOpenTable$()

if foobar.tab were in c:\temp\ then tablocation would print "c:\temp\"

It seems the closest is truefilename$() but that only prints out the current
directory, which is not the same as the directory from which the file was
opened.

Thanks in advance to anybody with the answer to my $20.50 question

MI SUM: returning the directory structure

[Humphrey, Ben]

Kudos to those who helped, I found exactly what I was looking for so for
those who are still curious...

tablocation = PathToDirectory$(TableInfo(mytable, TAB_INFO_TABFILE))

As for the other question I posed today about deleting a range of records,
I'm not going to even touch that one, but thanks to those who responded to
that one as well  (go ahead and have a laugh on me if you want).  I just had
my head backed into a corner I couldn't think of the obvious way to do it
(select * where rowID = yada yada yada) then delete from selection.  Okay so
I guess i got into it a little...

MI finding files in a windows directory whose name contain a specific string

[Humphrey, Ben]

Baby steps outside the mapinfo environment...

I was wondering if it is at all possible to somehow query the windows
environment about the files contained in a specific directory.  The idea I
had was that I would query a directory where an open table resides for a
file containing a certain string in its name.

For example if I had denver.tab open from a certain directory I would want
to search for any tables in that directory whose name contained the string
"buffer"

Can it be done???

And since it has always been the case in the past, there will be a reward.
This time, seeing that it is a more complex question, my first born child is
up for grabs.

MI RE: Overflow error message

[Humphrey, Ben]

I just posted a question along the same lines, with regards to overflow
errors when appending tables.  The error is most definitely happening during
the insert statement, although I'm waiting to hear back too.  My only guess
is that it has something to do with a max number of records you can have in
a table.  That's just a guess though...

MI lat/long to WGS84 - shouldn't there be a difference!?

[Humphrey, Ben]

So there I was saving a table from lat/long into lat/long WGS84 and I
realized upon completion that there was absolutely no difference between the
coordinates before and after the projection.

So my questions are:  Is there a difference?  Shouldn't the coordinates
shift a little between projections?  I've never dealt much with changing
projections so I am at a bit of a loss here.

Thanks to anybody who can provide some enlightening suggestions.

MI wacked out line length calculations

[Humphrey, Ben]

Okay, here's something COMPLETELY messed up.

I am conducting some length calculations on some line data for the US
railroad network.  I did a select objects from the railroad table that
intersect another table of polygons.  I save that as a table.  I then do a
select sphericalobjectlen(t_name.obj, "mi") into sometable, calculate
statistics, and get a the sum, for each row in the original table selection
of line lengths.  If I do it that way, I get over 6000 miles (which is way
off if you just look at the selection in a map window.  If I combine all
line objects into one, and then double click on the single object, I get a
line length of only 1000, which seems much more reasonable.  Anybody have
this experience before or am I using the wrong mapinfo commands?

Thanks
