Re: MI Updating Object Styles

[Michel Larue]

Hello,

I made a little utility that can copy and paste a style from object to 
selected objects. It might help you.

RE: MI Maps of Niue

[Clifford J. Mugnier]

Paula,

One of my Ph.D. students did the complete readjustment of 
the Tomb Point Datum for Niue last semester.  It was a 
series of interlocking classical traverse loops with 
several co-located geodetic-quality GPS stations.  The 
project is 100% complete, and I have the standard topo map 
of Niue in which the "atlas grid" is actually the local 
survey grid with 1Km grid blocks lettered for the tourists. 
 The entire project was adjusted with a rigorous least 
squares network adjustment with the latest debugged version 
of "ADJUST" by the U.S. National Geodetic Survey.

I can't release the stuff to you yet because I have not had 
time to send the Government of Niue a copy of the final 
report.  Maybe I can do it this week ... when they approve 
it then maybe I can ...

HOWEVER,

Whatever happened to the copies of McCaw's books on Viti 
Levu, Vanua Levu, and Taveuni, as well as a copy of Mike 
Poidevin's report that Litea Biukoto (of SOPAC) promised 
she was going to send to me last September?  (That's 
September 20, 1999).

I'll let you see mine after you let me see yours ...

Subject:MI Updating Object Styles

Mappers:

Is there a way to update an object's style programmatically 
without recreating the object?

A snippet of sample code from the MapBasic Help file says:

'set a new "current symbol style" 
sSymbolAttr = "(35,65280,22)"
sCmd = "Set Style Symbol MakeSymbol" + sSymbolAttr
Run Command sCmd

' use an Update statement to create a new Point for 
' every row in the Selection table.  Each new Point
' will use the new "current symbol style" 
Update "Selection"  
  Set obj = CreatePoint(CentroidX(obj),CentroidY(obj))

However, I need to do this for polygons!

When working in MapInfo, I can go to "Options | Region Style"
and modify editable, selected objects in the current window..
but that doesn't seem to work from within MapBasic (?)

I understand maybe I need to loop through each polygon and
modify them using Alter Object?

Thanks in advance for any insight!

RE: MI MapXtreme problem loading geoset

[Paul Grambauer]

Hamish,
I've struck this with MapExtreme too, but in may case, the layers that I 
used in the geoset were located on a network drive. It seems as though you 
may have the same problem. What happen with me is that MapExtreme or should 
I say the web server can only access local drives unless you use a suitable 
network client (in my case Microsoft Client for Novell NOT the Novell 
Client). Thus the calls to MapExtreme via ASP cannot open the tables 
because the web server cannot see the files, hence it works using MS Access 
to call MapExtreme because you are bypassing the Web Server.

Confused ?

Subject:MI MapXtreme problem loading geoset

Hello All,
I'm having trouble loading a geoset in MapXtreme. The geoset can be quite
happily loaded using the geoset manager on the server but seems to stall
when I try to load it through ASP. The geoset has approx 50 layers which
makes we wonder if the object within VB script has some kind of limitation.
To illustrate the problem I've stripped out all the ASP library stuff...

<%@ Language=VBScript %>
<%
Dim oMap
Dim oSess

Set oMap = server.createobject("MapInfo.MapXcourier")
Set oSess = oMap.GetMapXFromNewServer("E:\Program
Files\MapInfo\MapXtreme\Maps\testmoss1.gst")
'COMMENTSet oSess = oMap.GetMapXFromNewServer("E:\Program
Files\MapInfo\MapXtreme\Maps\newmoss.gst")
oSess.setsize 1200, 1200
oSess.ExportMap
"E:\Inetpub\wwwroot\MossMap_Dev\MarketingMap\mapimage\hamish.gif", 2
Set oSess = Nothing
Set oMap = Nothing
%>


http://mosssql/mossmap_dev/mapimage/hamish.gif" BORDER=0>


when debugging the ASP , the program seems to hang on the
GetMapXFromNewServer for up to a minute then returns oSess as
Nothing.(newmoss.gst is a test geoset with a just 5 layers or so as a test
which works) (I've extended script timeout and session timeout to 10 mins 
so
it's not the script timing out)


The same code as a test in Access '97 on the server loads the geoset
fine.

Sub testmapper()
Dim oMap
Dim oSess

Set oMap = CreateObject("MapInfo.MapXcourier")
Set oSess = oMap.GetMapXFromNewServer("E:\Program
Files\MapInfo\MapXtreme\Maps\testmoss1.gst")
oSess.setsize 1200, 1200
oSess.ExportMap "E:\Inetpub\wwwroot\MossMap_Dev\mapimage\hamish.GIF", 2

Set oSess = Nothing
Set oMap = Nothing

End Sub

Server is running IIS4
Can anyone tell me where to go next. I suppose in theory I could do all the
map generation in a VB dll as a wrapper to MapX but I don't see why should
'reinvent the wheel'.

I'm no IIS or ASP expert so any advice would be gratefully reveived

Hamish

RE: MI MB : get the layer back with former settings after modifying structure

[PERRY Chris]

Pancho/Francois,

I think the easiest thing is to save a workspace, alter the table structure,
then close all and restore the workspace. A simple MBX could be written to
automate this.

Hope this helps,

Subject: MI MB : get the layer back with former settings after modifying

Hi all

It is sometimes necessary to create a variable in a table in order to
store some information generated by a subroutine.
Altering the table structure closes the table. How can we restore it (in
the case, of course, several layers are opened in the same windows) with
its former position AND display settings ? I am aware that these
parameters are available through different functions but it is a real
burden of loops and variables to determine them. Is there a direct and
easy way to do it ?

With my anticipated thanks
Pancho

I was wondering if anyone had used the program to create points along a 
polyline at a nominated interval and then somehow labelled each point 
sequentially. ie I have a road that covers 300 km and I have created points

Any ideas?

MI Oracle 8.1.5

[Robert Southern]

I am struggling to make a connection through MapInfo 5.5 to Oracle 8.1.5 
spatial.

I have created a table in Oracle 8.1.5 called geom_test, it contains two 
fields Name and Geometry.  The table has two spatial geometries inserted:
poly with hole and
line

We have created the mapcatalog with no errors, however, when we try and 
connect to the table MapInfo displays an item called object in the fields 
for the table, which I have not seen before and appears to be somthing 
MapInfo has derived - is this correct ?

We also get an ORA - Error 00904, which is an invalid field name.  Has 
anyone any experience of this problem and what would be the best course of 
action.

Is our problem anything to do with the object or is this normal for MapInfo 
5.5 ?

I appreciate your help,

MI Fire Station Location

[Tim Rood]

I've received an inquiry about locating fire stations based on the travel
time to properties in its vicinity.  I don't know the exact problem they
need to solve, but it's of the nature of  "We need to site a fire station
so that its coverage territory minimizes the overlap with the coverage
territory of other stations we have and is within five minutes travel on
the street network of any property in its coverage territory."  I haven't
done this kind of analysis before and it would seem like the street network
data would have to be somewhat richer than your standard street centerline
data; it might include road width, lanes, signals (not that fire trucks
would stop for them, but), traffic direction (i.e., one way streets,
etc.) and other things that might have an impact on moving one or many fire
trucks around town.  Of course, responding is not the only aspect of site a
fire station, but I think I'm more well-prepared to deal with the land use,
zoning and development issues involved than with the time/distance part. 
If you know a little bit about this subject, I would appreciate your advise
on applications and data sources for doing this kind of analysis.

I have to admit my first reaction on seeing your msg was
to slap the delete key. When I ran into it again on the
MI list I actually read it asnd realised it was relevant
and not really spam. Anyway the point is, we are getting
hypersenstive to anything which even resembles unwanted
and irrelevant commercial intrusion. You know, like too
much exposure to certain kinds of dust or pollen can
provoke allergic reactions to benign paticles.

In this case I don't think you had to apologize (although 
it is good that you did). Your subject line was very 
clearly labeled as  an AD and perhaps now there are a few 
more people who will notice that and filter by it.

MI One vs. Many Objects

[Stephen R. Riese]

Greetings,
I tried an experiment and the results are not what I expected.  I'd like to
know if my results are an anomaly or should be expected.

I have a procedure that examines each object (about 200) in a table for
intersection with a given object.  I tried this two ways:

1)  Individual objects in the table are left as individual objects.

2) The objects are combined into one large object (and the table now has
only one row).

I expected the intersection detection routine to work faster in situation
number 2, where there is only one object.  In my trials, there is a slight
improvement, but not much.  Situation 1 actually is faster in some (few)
cases.  Any thoughts on this and the inner workings of the "Obj1 Intersects
Obj2" function?  I'm thinking that 200 objects in a table might not be
enough to produce a significant difference, but that if there were, say, 
2000 or more objects I might see a difference.

Thanks,
Steve

Hello,

  I am having a problem linking to my MS SQL 7.0 server via ODBC.
  I also have MI 5.5

I am able to create a create a DSN and I can at least get as far as opening
the table.  However, I do get an error when opening the table but it still
shows me the data.  The error I am getting here is: "[Microsoft][ODBC SQL
Server Driver]Connection is busy with results from another hstmt"... but
like I said I can still open the data up in a browse window.

Now It will also not let me make the table Mappable.  I even went into the
the SQL DB and manually created a MAPINFO_MAPCATALOG table and for some
reason it still says that I don't have a map catalog and can not make the
table mappable.  I have check my table over and over and it appears to be
correct.

Let me know

More creepy crawlies?
I've found that when I set an E-size page to landscape on a HP1050C, the new
layout window comes up portrait, and you have to switch the Page Setup again
to get it to stick. I think it's trying to go to your Windows Default
printer.
Also, the little Preview button you click to change the style of a region in
a dialog box doesn't update with the new style when you change it.  It was
kind of confusing at first, I'd keep going back in to check if I'd actually
changed the style.

apps. Only we wouldn't know where to start...

Does anybody know of any good sources of information on this matter?

MI Unsubscribe

Title: MI Unsubscribe

MI - find item

[Tom Manson]

Dear List,

I would like to have a couple of map windows open, each showing different
views (locations) of the same map. When I do Ctrl-F to find a point in one
map window, all of the other map windows also change their view to centre on
the same point. This happens both when I clone a view and create a new one
with the same tables. Is there anyway to prevent this from happening, so
that I can search in one map window and not have it alter all windows?

Thanks in advance,


Tom

MI MB : get the layer back with former settings after modifying structure

[Francois Molle]

Hi all

It is sometimes necessary to create a variable in a table in order to
store some information generated by a subroutine.
Altering the table structure closes the table. How can we restore it (in
the case, of course, several layers are opened in the same windows) with
its former position AND display settings ? I am aware that these
parameters are available through different functions but it is a real
burden of loops and variables to determine them. Is there a direct and
easy way to do it ?

With my anticipated thanks
Pancho

Re: MI ONError command

[Richard Greenwood]

I'm not sure if this will help, but here goes; rather than use On Error to
trap a condition where there are no mathcing records you can use to see how
many matching records there are, and if there are none, the handle the
error yourself. For example:

Select * from YOUR_TABLE where YOUR _FIELD Like YOUR_CRITERIA into Selection
i_check = SelectionInfo(SEL_INFO_NROWS)
if i_check > 0 Then
' it morked, do something
Else
' It didn't work, alert the user
Note "No matching Records"
End If

RE: MI Mapinfo v5.5 Patch (printing bug)

[Jason Adam]

More creepy crawlies?
I've found that when I set an E-size page to landscape on a HP1050C, the new
layout window comes up portrait, and you have to switch the Page Setup again
to get it to stick. I think it's trying to go to your Windows Default
printer.
Also, the little Preview button you click to change the style of a region in
a dialog box doesn't update with the new style when you change it.  It was
kind of confusing at first, I'd keep going back in to check if I'd actually
changed the style.

RE: MI Intersections

[Jeff James]

Anton,

I can answer the first part of your question regarding intersections in
MapX: Yep.  It's just the same as MapInfo's intersections.  It'll return a
point at that intersection, a FindFeature object with a CenterX and a
CenterY.

Don't know the answers to the API questions.

Good luck,

Hi All

Is the syntax of Street && Street for finding intersections the same in MapX
as it is in MapInfo.  I have look at the help and the results of the search
have the same structure, but the MapX help does not explicitly state the
syntax of finding intersections.

Does anyone know the declaration of the API calls GetRValue, GetGValue and
GetBValue in MapBasic.

Yours

MI ONError command

[Yvonne Hau]

HI

I am getting really lost in trying to use the OnError Command. I don't know 
much programmning, so this could be the reason why. What I am aiming to do 
is when I have selected a point, but discover that there is no records 
within the table, I want to give out a message saying that there is no 
records, and then come out of the loop, and start from the beginning of that 
particular sub. At the moment, I keep having to start from the beginnning of 
the program...and there are too many markers if I had to do that all the 
time.

So please advise me,

THanks in advance

MI MapXtreme problem loading geoset

[Hamish George]

Hello All,
I'm having trouble loading a geoset in MapXtreme. The geoset can be quite
happily loaded using the geoset manager on the server but seems to stall
when I try to load it through ASP. The geoset has approx 50 layers which
makes we wonder if the object within VB script has some kind of limitation.
To illustrate the problem I've stripped out all the ASP library stuff...

<%@ Language=VBScript %>
<%
Dim oMap
Dim oSess

Set oMap = server.createobject("MapInfo.MapXcourier")
Set oSess = oMap.GetMapXFromNewServer("E:\Program
Files\MapInfo\MapXtreme\Maps\testmoss1.gst")
'COMMENTSet oSess = oMap.GetMapXFromNewServer("E:\Program
Files\MapInfo\MapXtreme\Maps\newmoss.gst")
oSess.setsize 1200, 1200
oSess.ExportMap
"E:\Inetpub\wwwroot\MossMap_Dev\MarketingMap\mapimage\hamish.gif", 2
Set oSess = Nothing
Set oMap = Nothing
%>


http://mosssql/mossmap_dev/mapimage/hamish.gif" BORDER=0>


when debugging the ASP , the program seems to hang on the
GetMapXFromNewServer for up to a minute then returns oSess as
Nothing.(newmoss.gst is a test geoset with a just 5 layers or so as a test
which works) (I've extended script timeout and session timeout to 10 mins so
it's not the script timing out)


The same code as a test in Access '97 on the server loads the geoset
fine.

Sub testmapper()
Dim oMap
Dim oSess

Set oMap = CreateObject("MapInfo.MapXcourier")
Set oSess = oMap.GetMapXFromNewServer("E:\Program
Files\MapInfo\MapXtreme\Maps\testmoss1.gst")
oSess.setsize 1200, 1200
oSess.ExportMap "E:\Inetpub\wwwroot\MossMap_Dev\mapimage\hamish.GIF", 2

Set oSess = Nothing
Set oMap = Nothing

End Sub

Server is running IIS4
Can anyone tell me where to go next. I suppose in theory I could do all the
map generation in a VB dll as a wrapper to MapX but I don't see why should
'reinvent the wheel'.

I'm no IIS or ASP expert so any advice would be gratefully reveived

Hamish
