RE: MI-L Re: RE:MI-L Off-topic: c++ porting problem- gnu c++ to MS .net c++

[Warren Vick, Europa Technologies Ltd.]

Hello Phil,.
 
I think I can help you with the second part of your query.
 
The error is actually quite a good one but the reason why the warning is
produced needs a little background information on how C++ implements OOP.
The error is generated because your class has members that are pointers...
distance, depotdist and name. Obviously these are assigned or allocated
space somewhere in your class methods. The problem is, however, that you do
not have a copy constructor or assignment operator method (these are the two
the warning complains about). So, with the absence of these, when you
construct a copy, or assign, an object of class Gene, a binary copy of the
object is made in memory. The danger here is that the pointer values will be
copied to the new object and you will end up with two objects which
internally have pointers directed to the same space. i.e. change one and the
other will change too. This is generally, but not always, undesirable and
could cause some nasty bugs which are difficult to track down.
 
The solution is to always have a copy constructor and assignment operation
function is your classes. It's generally good OOP practice.
 
As for a dummy's guide to the errors, I'm afraid it's just a case of
experience. If it was easy, C++ development wouldn't be regarded as a value
skill!

Dave,
 
That change made the code more readable and pointed me in the right
direction. I tried  the -pedantic switch in gcc. 
 
"chromo.cc:15: error: ISO C++ forbids array dimensions with parenthesized

So: 
myChromoPool = new pChromo [popSize];
now works in VS.
 
Thanks for the help. I have attached the header file for the other problem
if you're able to look at that.

Phill,

try using a typedef (a synonym for another type) declaration as a pointer to

the Chromo vector

i.e

typedef Chromo* pChromo ;

then change your code to
pChromo *myChromoPool ; // Chromosome vector
myChromoPool = new (pChromo)[popSize]  ;

Not sure about the second problem as I would have to see the header file.

MI-L DSN Less DBMS Connection

[Milo van der Linden]

Hello list,

I am using DBMS tables of a variety of types in a VB-programmed integrated
mapping project. My MapInfo version is 7.0.

Within my VB-program I use DSN less connections meaning that no Data Sources
(ODBC) need to be manually configured on the clients installation
workstation.

I was wondering If this can also be done for a DBMS connection from MapInfo?
Is it possible to change the ODBC-parameters in the Server Link statement
from 
"DSN=MY_DSN_NAME" 
to something like 
"Provider=Microsoft.Jet.OLEDB.4.0;User ID=Admin;Data Source=MY_DATABASE;"

Anyone has some experience on this? Or should I change to a higher version
of MapInfo and will it be supported then?

Kind regards,

RE: MI-L DSN Less DBMS Connection

[Peter Horsbøll Møller]

Well, it is kind of possible if you use the File DSN in stead. In this case you 
can place the DSN file at the same folder as your application, and so you don't 
need to create any DSNs using the ODBC-datasoruce dialog.

And your connect string would look like this:

"FILEDSN=" & ApplicationDirectory$() & "SPVector.dsn"

Actual I think that the connection you use in MapX is a OLEDB connection (?) 
and not a ODBC connection, so can't quite compare those.

When MapInfo Pro .NET will be here I guess it will support OLEDB or other DSN 
less connections.

MI-L Mouse button

[Mehmet Doldur]

Hi list,
I use VB.NET and MapBasic 7.5
When the main map has been changed (zoomin,zoomout,pan,going to select 
etc.) i want to move the rectangle object on the overview map. I think 
after the mouse up i should move the rectangle to the new place. But i 
don't know how can i get if the mouse button is pushed or not or which 
mouse button(left or right) is pushed on the main map. Some code below, is it a 
right 
way? help please.

lPlace = InStr(newText, " ")

xKoord = Mid(newText, 1, lPlace - 2)

yKoord = Mid(newText, lPlace + 1)

mdiWindow.MdiSBar.Panels(1).Text = "X : " & xKoord & " Y : " & yKoord

 

'Check if the mouse button is pushed

If mapInfo.Eval("CommandInfo(" + Str(CMD_INFO_X) + ")") <> "0" And _

'Move the rectangle

End If

MI-L SUM: MapInfo Pro and Oracle 10g Spatial

[Peter Horsbøll Møller]

Thanks for the replies.
 
Here are the advice I got:
 
1. Start installing the Oracle Client before you install MapInfo
2. Use the Dependency Walker tool to check if nessessary dependencies for the 
MIDLOCI.DLL are found. This is nessessary for the DLL to be loaded.
3. Pray !!
 
And of course it was the later that worked for me - I'm cetain ;-)
 
I uninstalled the Oracle Instant Client and reinstalled it - still with MapInfo 
7.8 installed. This time I not only installed the Instant Client but also some 
other client tools like SQL Plus etc, so whether this is the thing that helped 
or if it was the reinstallation I wouldn't know.
 
After this I had some trouble making the connection to the Oracle server using 
the Net Configuration Assistant. So I decided to call it a day, and went home.
 
Today I found a TNSNAMES.ORA file on another computer, copied it to the 
computer I was working on yesterday, and surprice - It is working.
 
So I guess I most have been praying in my sleep.
 
Well anyway, I'm am up and running and a happy man

Subject: MapInfo Pro and Oracle 10g Spatial


Hi,
 
Just a very simple simple question, that I'm sure every one knows the answer to 
- or at least those working with Oracle:
 
What do I need to install on a computer that should be able to access a Oracle 
10g Spatial database ?
 
On my own laptop I have installed the complete Oracle 10g database with SQL 
Plus and TOAD etc. But these computers are supposed to use MapInfo as a client.
 
Having just installed MapInfo - of course with the Oracle OCI support - I get 
the message that some drivers failed to load when I start MapInfo. This is 
normally caused be the fact that there is no Oracle Client installed.
 
I then installed the Oracle Instant Client, but this didn't help.
 
What else do I need to do ?
 
TIA,

More random thoughts on SQL.

If you are not one yourself, make friends with a good database 
administrator.  They are worth their weight in gold.

And be careful about restricting access to various tables in the database 
- eg. users need to be able to see the base tables - something dbas don't 
like.  MapInfo needs to select from those tables and fails if you try to 
edit them via views with triggers.

We had a conference with a few seurity nazis, and their assessment was 
that they couldn't impose the same sort of restrictions on the database as 
they would like to normally (eg. only see views and only edit via 
triggers), and suggested creating a differnent instance of SQL Server that 
held only the GIS data as being the best compromise.

I'll keep posting these as I think of them.  It is good for my records as 
well.

MI-L US States LINE file

[Will Mitchell]

Hi all,

 

Anyone have a US State outline dataset as Polylines, preferably without
coast or with coast attributed/identified?  Need this for cartographic
purposes and am hoping to not have to build it.

 

Cheers!

MI-L using Visual C++ Macros from MapBasic

[Christophe Brabant]

Hi everyone
 
I would like to use Win32 API like LoadCursor and SetCursor. The second
argument of LoadCursor is returned by the Macro called MAKEINTRESOURCE
 
For example, IDC_WAIT = MAKEINTRESOURCE(32524)
 
The macro definition in Winuser.h is :
 
(for Ascii)
#define MAKEINTRESOURCEA(i) (LPSTR) ((ULONG_PTR)((DWORD)(i)))
 
Hor could I include that into the MapBasic program ?
 
Thank you

MI-L Looking for HELP on radius search.

[Nick Vrbos]

I have a table with a column containing latitude information to the 6th
decimal point.  The same goes for the longitude co-ordinate column.

What I am looking for is :
    1.  A radius search results from one of those lat/long points from
a user selection of 100 metres to a max of 2000 metres (2km.)
    2.  What is the precision/accuracy of
the 5th or 6th decimal point?  In other words, does the 6th decimal
represent a foot or a metre or a kilometre?

I am not looking for a map engine to determine this for me.  I think I
need an algorithm.  Does anyone know where to lead me to a programmed 
solution to this problem?  Where can I find information on the lat/long
accuracy of each decimal point?

Thanks.

MI-L Futur or MapXtreme Java

[Gilbert Haché]

Hi group

 

I would like to have your opinion on MapXtreme Java. What's happening with it? 

 

We see a lot of improvement on the MapXtreme .net version and it's 
understandable, but the Java version is still in use and improvement are not 
coming out!

 

Have you heard about future upgrades, new features, etc? Did someone hear that 
Mapinfo will let it die?

 

I would welcome any comments... 

 

 

Thanks!
