Re: [mapguide-users] ECW file with mapguide 2.4 and gdal 1.9

[Jonio, Dennis (Aviation)]

Mange,
I have 2.4 RC1 working with GDAL 1.9. I just followed the procedure outlined 
for one of the older releases(gdalplugins directory and copy some files around) 
and it seems to work fine. 
However, I do not use ECW but use MrSiD. Process should be the same.

Re: [mapguide-users] Map takes very long time

[Jonio, Dennis (Aviation)]

David,
The only thing that I found to do was turn all of my vector layers into SDF 
format and publish those. This helped but did not resolve the issue. (Kinda' 
sorta' defeats the purpose of FDO but I had no choice)
This is NOT a flame against Mapguide but just to let you know ... It took about 
3 months of learning curve and coding but I have written my own DESKTOP mapping 
application using the SharpMap 0.9.Trunk-2011.11.17 iteration on Codeplex as a 
base. Works great, users love it, no wait...and depending on options an xcopy 
install.

RE: [mapguide-users] Join between an Oracle spatial table and a view

[Jonio, Dennis (Aviation)]

Iulia,

I would recommend:

1)  Create a “normal” Oracle view w/your join

2)  Add the entry for it in user_sdo_geom_metadata. (No need for an index.)

3)  Create a layer for the view … 

Does all appear normal and as expected? 

All that I am suggesting here is to gradually add complexity. No need to boil 
the ocean from the get-go. You can delete/remove this stuff later.  But maybe 
you have already done these things.. in which case I am no help.

RE: [mapguide-users] fusion viewer performance vs basic viewer

[Jonio, Dennis (Aviation)]

IMHO, the fanfare surrounding Fusion was just that. Great promise,
beautiful presentation but as you have surmised, terrible performance. I
have tried a couple times over the years to make a fit for us but it is
just a nogo.
There has been some posts in the past about the future direction of MG
and I am becoming more pessimistic all the time. I really have no right
to flame or complain since our financial contributions has been nil.
It is my guess that MG will languish and wither unless significant
effort is put into utilizing a couple of those "specialized" plugins.
But there seems to be this religious fervor NOT to do that, O'well...
Anyway, in answer your question; We do not use Fusion and I gave up
trying.

RE: [mapguide-users] Re: how to convert agf to wkt?

[Jonio, Dennis (Aviation)]

The WKT string that you have posted does not pass: 
SOD_UTIL.VALIDATE_WKTGEOMETRY. I do not know what version of Oracle you are 
using but if my  memory serves the WKT functions and procedures were/are very 
limiting. I do not believe that the 10g versions support curves. In addition I 
thing the syntax is somewhat different than AGF/FGF. 

From the Oracle docs:

To be valid, the input geometry must be in the well-known text (WKT) format, as 
defined by the Open Geospatial Consortium and the International Organization 
for Standardization (ISO).

This function is patterned after the SQL Multimedia recommendations in ISO 
13249-3, Information technology - Database languages - SQL Multimedia and 
Application Packages - Part 3: Spatial.

To validate a geometry in the well-known binary (WKB) format, use the 
SDO_UTIL.VALIDATE_WKBGEOMETRY 

  function.

RE: [mapguide-users] Re: Mapguide won't display all features fromKing Oracle connections

[Jonio, Dennis (Aviation)]

Haris,
Apologies for my poor explanation. 
Yes, you did fix gtype=4. Works just fine, DB wise. _MapGuide_ does NOT render 
4's. It does render the other multi-gtypes = 5,6 and 7.

Like I said, I have always constructed _circle_ objects as 
INFO_ARRY(1,1005,1,1,2,2)'s. I was skeptical from the beginning about Oracles 
_optimized point_ so I make those as INFO_ARRAY(1,1,1) and the Oracle 
_rectangle_ becomes a INFO_ARRAY(1,1003,1,1,2,1) w/all 5 ordinates.  A couple 
days ago I experimented w/Function:
 OnCircleDigitized(Circle) {
r = Circle.Radius;
p1x = Circle.Center.X + r;
p1y = Circle.Center.Y + r;

p2x = Circle.Center.X - r;
p2y = Circle.Center.Y + r;

p3x = Circle.Center.X - r;
p3y = Circle.Center.Y - r;

p4x = Circle.Center.X + r;
p4y = Circle.Center.Y - r;

ords = p1x + "," + p1y + "," + p4x + "," + p4y + "," + p3x + "," + 
p3y + "," + p2x + "," + p2y + "," + p1x + "," + p1y;
//tmp = "MDSYS.SDO_GEOMETRY(2003, 2236, NULL, 
MDSYS.SDO_ELEM_INFO_ARRAY(1,1005,1,1,2,2), MDSYS.SDO_ORDINATE_ARRAY(" +
//ords + "))";
tmp = "MDSYS.SDO_GEOMETRY(2003, 2236, NULL, 
MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,4), MDSYS.SDO_ORDINATE_ARRAY("
+ p1x + "," + p1y + "," + p2x + "," + p2y + "," + p3x + "," 
+ p3y + 
"))";
var geometryInput = 
document.getElementById("currentscribblegeometryInput");
geometryInput.value = tmp;
tmp_control = document.getElementById("sessionName");
SESSION = tmp_control.value;
tmp_control = document.getElementById("mapName");
MAPNAME = tmp_control.value;
tmp_control = document.getElementById("textForFeature");
TEXT = tmp_control.value;
tmp_control = document.getElementById("currentscribbleText");
tmp_control.value = TEXT;

MiMethodsMgr.InsertUserSessionFeature(SESSION, MAPNAME, TEXT, 0, 
geometryInput.value,
OnCompleteUserSessionInsertMethod, 
OnError_Generic, OnTimeOut_Generic);

}
And found that my _ORACLE circles_ were _Oraclewise_ valid BUT I get the 
_failed to stylize-my bad_ error in the log and the layer does not render.
As a side note FDO Toolkit fails to read a table w/a Oracle _circle_. (By the 
way, I do this insert via OracleConnection NOT MapGuide/FDO. I must do validity 
checking before the insert. So if there is/was an issue I would not have seen 
it here.)

I hope I have done a better job in explaining? I am very, very pleased 
w/KingOra. Oracle itself has done a poor job in explaining that Oracle Locator 
is all that is required to do the basics and it is totally FREE. With the sheer 
weight of Oracle's experience w/geometry objects I certainly believe you have 
hit the mark w/this provider! Kudoes to you!!! 

Haris, IMHO, there is absolutely NO advantage in storing INFO_ARRAY(1,1003,4)'s 
over INFO_ARRY(1,1005,1,1,2,2)'s.

dennis

Hello Everyone

I am working on a map application that displays water sample stations.

Each station is represented by a point on the map that can be clicked to
activate a url to show station data.

Many of the stations are two in one and share the same lat/lon.
Therefore,
two points are in the exact same spot on the map and I can only get the
url
to activate for the point that ends up on top of the other.

Is there any way to give the user a choice of which point they are
trying to
activate if there are multiple points in the exact same spot?

Thanks

RE: [mapguide-users] Re: How to render MgMultiGeometry

[Jonio, Dennis (Aviation)]

Zak,
I did do just a bit more research. Yes, you dialoged on the issue back
in Dec. 2007 and it looks to me that the _issue_ has gotten worse or, at
best, stayed the same.

>From the FDO API reference:
The FdoIMultiGeometry class is a heterogeneous MultiGeometry type. 

>From the MapGuide API Reference:
An MgMultiGeometry is a heterogeneous aggregate of one or more
MgGeometry objects. 

I went ahead and tested the homogeneous _multi_geometry types with the
SDF and KingOra providers, both seem to work well with all of the types.

As far as heterogeneous geometry objects(point,line), (line,surface) go,
as I noted earlier, KingOra adds the record but with a null geometry
column. SDF does not even add the record. No error in the logs. Looks
like Gunter is outa' luck.

For my part I am not going to pursue the issue since we have no real
practical use for those types of collections but I can envision them
being useful for some.

MapAgent should be accessible under /mapguide/mapagent/mapagent.fcgi
with the tests under /mapguide/mapagent/index.html (or something like
that)?

 

For some subset of functionality (that used by developers and active
testers) Fusion works great, and is a lot faster than previous versions
especially if you do a custom build. There are still performance
problems with maps containing large numbers of layers, and there are
probably lots and lots of edge cases out there to be stumbled over.  

 

It's a bit of chicken and egg.  If people don't start using/testing it,
the problems won't get found and fixed.  Of course, if they're found
there also needs to be reproducible test cases submitted to the Fusion
Trac instance, developer time to address, etc, so I wouldn't go into a
Fusion project expecting rapid deployment unless I had resources to
throw at it.

RE: [mapguide-users] Oracle 10g Standard

James,
This is relevant to 10g and 11g. There is much misunderstanding
concerning Oracle's support of GIS. Oracle Locator is a subset of Oracle
Spatial functionality within ALL of the Oracle database products
including Oracle Express. Yes, you may optionally not install it w/in
Standard and Enterprise. (I am not sure if you even have the option of
not installing if you are using Oracle Express.) Because Oracle Express
does not come with the built in java engine some WKT/WKB functionality
is not there.
I would recommend using SL King Oracle FDO provider. I works very well.
Oracle Express 10g is free and works very well. 
I have found absolutely no need for the additional functionality that
comes with the purchase of Oracle Spatial. FREE Oracle Locator provides
ample support for our needs at the moment.

I would rather see Autodesk make Studio available as a stand-alone product

RE: [mapguide-users] [MapGuide OSE FDO Oracle SL-King 0.8.5]HolePolygon Type 7 Problem

[Jonio, Dennis (Aviation)]

Your example shows sdo_gtype of 3003 not 3007. I was under the
impression that that was the issue?  Based upon what you have here the
contents of ELEM_INFO are in sync with the sdo_gtype. Polygon (straight
line segment inner ring starting a 1, straight line segment external
ring starting at 106) I cannot load this up myself, something must have
been corrupted via the email so I cannot check the ordinates myself.

RE: [mapguide-users] [MapGuide OSE FDO Oracle SL-King 0.8.5] HolePolygon Type 7 Problem

[Jonio, Dennis (Aviation)]

I would contend that your "... polygon with hole have only one exterior
boundary and the geometry type is 7" is NOT a valid SDO_GEOMETRY and
does not fall w/in the specification. What you describe is in fact a
??03 sdo_gtype NOT a ??07. Have you validated the geometry via
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT? Oracle will certainly store the
invalid geometry.

You might wish to check out the Oracle spatial forum:
http://forums.oracle.com/forums/forum.jspa?forumID=76
Some very, very bright folks prowl that forum.

I have no experience w/MGOS 2.0.2 service failure over a bad geometry so
I cannot speak to that.

RE: [mapguide-users] Scribble markup application question

[Jonio, Dennis (Aviation)]

Warren,

 

It has been some time since I wrote Scribble and my head is currently
into OBJECTARX/Oracle but I believe its purpose is to stuff the
currentscribbleselectionXMLcntrl.value for the dark-side. As to why,
well I just did it that way. Yes, that is exactly what it does.

As for the error it looks to me that I store the original but on exit I
never put it back. Since I did not do it, check out the 
"onunload" event. I would think you just have to put the original back.

mainFrame.OnSelectionChanged = originalOnSelectionChanged;

dennis

Subject: [mapguide-users] Scribble markup application question

 

I'd like to know if somebody that knows the Scribble app can explain why
the app implements a local selection changed handler and what the
purpose of it is: LocalOnSelectionChangedHandler

 

>From what I can see, it just sets the selectionXML to one of the hidden
fields, is this correct?

 

I've created a wrapper of sorts for the Scribble app that takes part of
the GT markup app for managing the creation and loading of 'local' and
global' markup resources based on a user login, and then the scribble
app for the feature creation.  The app works great creating and deleting
features.  However, when I exit the editing mode and close the
resources, the app goes back to the default Task Page.  At this point,
if I try to select objects on the map, a JScript runtime error is
thrown: "Can't execute code from a freed script" and the app stops on a
parent.OnSelectionChanged(); call in the mapframe.aspx.

 

I may be off-track on this error, but I think it has something to do
with the local onchanged handler in the Scribble app?

Any insight or comments would be greatly appreciated,  thanks so much.

What is the value of "nameQuery" ... what is it that you are trying to
select? Have/did you define your selection? What is it you expect to
see?
I would hazard to guess that your current issue has nothing to do with
the cast or no cast of MgLayerBase

Dennis, I am really sorry for making you confused because I mistyped the
code.
These are the original code that I copied from aspx that i got the first
error.

//Highlight the query result on the map
MgSelection selection = new MgSelection(map);
MgLayer layer = map.GetLayers().GetItem("Parcels");
featureReader = featureService.SelectFeatures(parcelId, "Parcels",
nameQuery);
selection.AddFeatures(layer, featureReader, 0);
String selectionXML = selection.ToXml();

I changed the line to  ---MgLayerBase layer =
map.GetLayers().GetItem("Parcels");--- 
as your suggestion but the Query result is still empty.

I am sorry.

RE: [mapguide-users] Oracle SDO Geometry to MgGeometry

[Jonio, Dennis (Aviation)]

1) You must(should) use Mapguide's FDO interface for this.
2) The Oracle SDO_GEOMETRY type is NOT a WKT type. 

If you find the above not to your liking you could do your own
translation from SDO_GEOMETRY to MgGeometry. I have done it but I found
it to be absolutely no fun at all. IMHO it would be best to stick with
Haris K's KingOra FDO implementation. Not perfect but it has come a long
way.

If you have not been already, look here:
http://code.google.com/p/tf-net/
and here: http://www.topologyframework.blogspot.com/ for additional info
on sdo_geometry, conversions etc.

No help but I have the same issue. I think the workaround is Version

If a layer preview fails you should generally add that layer to a new

Regarding King.Oracle, can you explain more what is going wrong ?

Latest couple of releases of King.Oracle are slow and there are Oracle
client/ King.Oracle build mismatches.
But even slow and memory consuming it should work :)

BTW, this week I will release newer version of King.Oracle with very
improved performance (multiple factor in some of my test cases).

Howdy, 
By doing one-thing-at-once I have found MrSid seems to work fine, at
least
in the short term. Poked and prodded no crashes.

Based upon my config here it appears then King.Oracle is broken. Yes, I

d20204668.html#a20209315
and others

S, I tried the the ArcSDE provider, again standard MGOS 2.0.2,
configs
fine, renders fine(little slow) HOWEVER when I do a selection, 1-x
features
it never returns. Alas lost in space ... 
Anyone?

Do I have to turn everything into an SDF?

Zac,

 

My experience with the "override thingee" has not been positive. It is
rather bizarre in my case ... hit refresh and it pulls in the "correct"
SRID from s-l king and shows the correct wkt!!! (same thing I get w/in
Map3d by the way)  ... anything I select for an override fails even
arbXY ... but then again, maybe I just don't understand ...

[Jonio, Dennis (Aviation)]

Alexander,

 

It looks like we share the same issue. The SRID that we use is 2236. 

I am certainly interested in how this gets resolved within MGOS. It
seems to me though that this is a non-issue for the rest of the
universe. 

My solution thus far has been to duplicate tables in Oracle and do a
transform to a WKT that MGOS "likes". Kind'a, sort'a brutal but it is
what it is.

Hi,
The Oracle SRID or rather the EPSG-Code is 24878.

Now I saw, that the WKTEXT which is shown in webstudio is a little bit
different to the WKTEXT in the MDSYS.CS_SRS - Table.
Could this be the problem? But what can I do for this?

IMHO, take a long deep breath and forget MG and KOP for the moment.

 

Download instantclient 10.2 from the Oracle site.

Install it.

Config  TNSNAMES.ora (although not necessary I would recommend that you
set the environmental variables as described: LD_LIB_PATH, TNS_ADMIN and
PATH)

Use the following to contact the db:  TNSPING 

 

When you get this working FdoKingOracle works great (as Haris K., et.al.
describe) ... 

1)   copy the 3 dll's

2)   update providers.xml

Hi Dennis,

 

The main osgeo wiki (wiki.osgeo.org) is different technology than the
wiki in the MapGuide Trac instance, and does use OSGeo IDs.  We don't
have single-sign-on though, so if you want to log in to the MapGuide
wiki, you have to click on the "Login" link under the search box and log
in there, not through the main OSGeo web site.  And you have to log in
every time you visit the site; it doesn't remember your credentials.

 

I'd be happy to post the zip and a description if you want to email it
to me offline.  My tech group just started allowing zipfiles through
again, so maybe I'll get lucky, but maybe not.  If not, I'll reply with
FTP details you can use.

does it show "logged in as xxx" on the line between the search box and

It's not very intuitive, but it's relatively efficient once you get used
to it.  Once you are logged in, you should just be able to put the new
URL that you want into the browser, and the wiki will ask you if you
want to create the page.

 

It's possible that you don't have rights to do this; I don't have access
to the Admin section in MapGuide Trac.  Let me know if it doesn't
present you with this option if you are logged in and put this link in
your address bar:

Hah,

 

I had already forgotten that Jackie was working on this kind of thing in
the Trac wiki.

 

I've done a bit of restructuring...  Would you mind trying to add a new
page with your code sample to this index and let me know how it goes?

 

http://trac.osgeo.org/mapguide/wiki/CodeSamples
<http://trac.osgeo.org/mapguide/wiki/CodeSamples> 

 

You will need an OSGeo ID to edit the wiki... there's a link on the main
page on how to get one of those.  You should also be able to attach a
zipfile to the sample page.

 

If the instructions on that page are not clear (and I'm pretty sure
they're not), please fix them or let me know what's missing.

 

Thanks!

Jason

Thank you for the explanation. I certainly understand your point

Hi Dennis,

 

Sharing the code is awesome, it's just not likely that it would make it
into the production code stream without either being cross-platform or
having equivalent functionality under the other supported languages.

 

There has been some thought given to setting up a "community" area to
facilitate code sharing, but I haven't heard anything about it recently.
In absence of that, I'll have to see whether we can set up some kind of
"code samples" area on the Trac wiki where you could write up a quick
explanation and then attach a zipfile with the code.

 

This community is incredibly active, but I think we need to understand
that the MapGuide Open Source project is not run by anyone but the
community.  Yes, Autodesk still does the majority of the coding (though
we are seeing more activity from others recently), but it's a true open
source project and its strength is going to be measured by the
willingness of its users to get involved in testing, development,
documentation and, in general, innovations like what you have done with
PDF output.

RE: [mapguide-users] Printing

[Jonio, Dennis (Aviation)]

Ok ...

Here goes. No, there is no "scaling". In this generation the
fundamentals are very, very simple ... Whatever the map shows gets
captured via RenderMap. In my case, RenderMap produces a PNG(could just
as well be a jpeg) that is passed on to iText methods that turn that
stream into an image which in turn is used to "size" the paper selection
for the PDF. The page is added to the PDF document and the PDF document
is streamed to the http response stream. Obviously all of the save,
zoom, select, pan and print functions of Adobe Reader are there. 

 

Here are the contents of scribblepdfdoc.ashx.

 

<%@ WebHandler Language="C#" Class="scribblepdfdoc" %>

 

using System;

using System.Web;

 

public class scribblepdfdoc : IHttpHandler {



public void ProcessRequest (HttpContext context) {

 

ScribbleMethodsMgr smm = new ScribbleMethodsMgr();

byte[] v =
smm.MaterializeMapPDFPage(context.Request.QueryString[0],

 
context.Request.QueryString[1],

 
System.Convert.ToInt32(context.Request.QueryString[2]),

 
System.Convert.ToInt32(context.Request.QueryString[3]),

 
context.Request.QueryString[4]);

context.Response.AppendHeader("Expires", "0");

context.Response.AppendHeader("Cache-Control", "post-check=0,
pre-check=0");

context.Response.AppendHeader("Pragma", "public");

context.Response.ContentType = "application/pdf";

context.Response.BinaryWrite(v);

context.Response.Flush();

}

 

public bool IsReusable {

get {

return false;

}

}

}

 

I choose to put the actual stream creation inside a class that contains
a whole lot more than just creating a PDF stream. There is however no
reason why that method could not be placed inside this helper. I have
done it before for other applications. 

 

I have gotten the impression from reading other pages on OSGeo that this
forum does not like submissions, of code, that do not meet their

Chris,

 

I decided before even starting on MGOS to output to PDF file format. Let
Adobe Reader handle all the printing output options and the zooming and
the panning and the  options,options,options. 

 

All my stuff is .NET specific. My boss has 'guidelines' after all ...

 

I have been producing PDF's  using "iText" for a couple years now and
irrespective of what I think the users love it. I will not burden you
with all the details but I am use "ikvm" in conjunction with "iText" ...
(this way I am able to stay up to date with "iText"). There is however a
.NET version of out there that is somewhat behind Bruno's work.

 

The guts of what I have done relies on RenderMap .. (MgByteReader
byteReader = renderingService.RenderMap(map, selection,
mapCenterCoordinate, mapScale, width, height, color,
imageflavor.ToUpper());

Has anyone built a printing app for MGOS?  I have a client that would
like to be able to print on a large format plotter.  I've not worked
with the printing functions and wondered if someone had already built
something that gives printing options and would be willing to share with

Maybe you are just making to many assumptions about what is under the

It takes a few more lines of code but I try to make it a practice to

Djonio, thanks for sharing the code. I'll try it and come out with
results.

BTW, did anyone notice that managed version of MgLayerCollection has
some
nasty problem when it comes to removing items?

Try removing MgLayer items by:

Dim layerIndex As Integer = map.GetLayers.IndexOf(layerName)
map.GetLayers.RemoveAt(layerIndex)

and it turns out that either IndexOf or RemoveAt doesn't perform well.
Or
maybe it's me doing it the wrong way?

Here is an example of a do-it-yourself login. Obviously .NET ...
James and Kenneth have given excellent ideas for alternative ways to
setup your resources. 

In this illustration within the "loginQ_Authenticate" you could do a
whole range of stuff based upon who is/was signing in.
Yes, I add items to the Session but this gives the most generalized

All users acess the same map (and layout), but the difference between

So, I am wondering if there is a mapguide security API that manages
users in
this way, or a security and login code ready for use.I'll be very

My problem is that users are not prompted for a login and password,

RE: [mapguide-users] Open map and Zoom to data

[Jonio, Dennis (Aviation)]

After spending some hours on this forum I have begun to use this
watchForInitializationComplete() function as the starting point for most
of my applications. You will obviously have to adjust the
"parent.parent.parent" stuff as I crowd as many as four iframes inside
the TaskPane. I do NOT use php. I have settles on ajax.NET 1.0 and mgos
seems to love it. I have been able to make mgos respond as if it were a
desktop application. Please forgive all the syntax errors in
processParms() ... I am just trying to explain the concept.

To reiterate what others have shown me:

var initTimer =
setInterval(watchForInitializationComplete, 250); 
function watchForInitializationComplete()
{ 
try { 
if(parent.parent.parent.mapFrame.GetMapName) 
{ 
//alert("within watchForInitialization
...");
var mapName =
parent.parent.parent.mapFrame.GetMapName();   
if ( mapName != null) {
var mapNameControl =
document.getElementById("mapName");
mapNameControl.value = mapName;
var legend_done = false;
if (parent.parent.parent.mapFrame.GetLegendCtrl)
{
legend_done =
parent.parent.parent.mapFrame.GetLegendCtrl().InternalStateComplete();
if (legend_done == true)
{
   //clearInterval(initTimer);
   var sessionNameControl =
document.getElementById("sessionName");
   sessionName =
parent.parent.parent.mapFrame.GetSessionId();
   sessionNameControl.value =
sessionName;
   try 
   {
 processParms();
clearInterval(initTimer);
   } catch(exp) { alert("...Error is
fatal: " + exp.message); }
   
 }
} 
}
} 
} 
catch(Exception) { } 
//catch(Exception) { alert("Waiting: Map has not finished
building. click and Retry."); } 
}

   function ShowViaZoom(x, y, scale)
   {
//alert("X:" + x +" Y:" + y +" Scale:" +  scale);
parent.parent.parent.ZoomToView(x, y, scale, true);
   }

some function like this to get your parms ..

  function processParms()
  {
var parameters = location.search.substring(1).split("&");

var temp = parameters[0].split("=");
l = unescape(temp[1]);
temp = parameters[1].split("=");
p = unescape(temp[1]);
document.getElementById("X").innerHTML = l;
document.getElementById("Y").innerHTML = p;
var X = l;
var Y = p;
ShowViaZoom(x, y, scale);
  }

You could make add another "hidden" frame to your frameset. Pass the
incoming
parameters to the hidden frame and perform zoom and selection actions in
this hidden frame.

Something like:


";
}else{
echo "";
}
   ?>




You will also have to check first in the hidden page if the map is
already
initiated before selecting and zooming. There are some examples on the
forum
how to achieve this.

RE: [mapguide-users] Newbie questions

[Jonio, Dennis (Aviation)]

Marty,

Q1: YES - (technically no ..)  Map3d does have a Publish to MapGuide but
you will be very, very disappointed in the output. DETE is a very
complex app especially when you have multiple "Maps" defined within
"Display Manager"  I cannot emphasis enough to take the time to
understand "Display Manager".  Because of the nomenclature it was
somewhat of a task for me to get the basics.

 

Q2: This site is great for MapGuide ... Trial/Error on the
Map3d->Display Manager->Map building functions. Be sure you fully
understand what "Map Base" is in Display Manager

 

Q3: Time will tell .

OK, I have MapGuide v 1.2 installed and working. Now I would like to put
it to use.

I have many AutoCAD maps done on USGS base that I would like to move
into this system.

The maps are from the telecommunications industry and have many defined
blocks with attributes and layers.

Right now I have AutoCAD and AutoCAD Map both 2008 and have ordered the
AutoCAD MapGuide Studio trial CD.

 

Question 1. Do I need MapGuide Studio to do this or does MapGuide Web
Studio have the same functionality?

 

Question 2. What is a good source of information for learning how to do
this? Are there any tutorials or documents related to this? 

 

Question 3. Am I posting this to the right group or is there another one
for these types of questions?

 

Any source of information that you may feel pertinent is welcome.

 

Thanks,

Marty

RE: [mapguide-users] MapGuideDotNetApi error

[Jonio, Dennis (Aviation)]

Kenneth,
First off ... thank you for your response. Yes, I was terse. I
apologize.

I already had four distinct MG application running under the
"standard-out-of-the-box" MG configuration and all works very well. So
this additional app failure was a complete surprise. I included a bunch
of .NET AJAX 1.0 functionality in this app so I assumed(for a awhile)
that that was somehow the issue. It was not.

To get to the point ... I did not gracefully shutdown MG server and IIS
when I did the copy over to the server from the development box. During
my "sanity-check" I did then in fact shut everything down properly.
After doing this there remained 2 extraneous MG processes! (I kept
getting this "lock" on ACE.dll). I have absolutely no idea how or why.
After killing those and copying over my new app and starting things back
up PROPERLY all worked well. 

All my fault ... and another lesson learned about the "robustness" of
IIS.

BTW: The .NET AJAX 1.0 Toolkit extenders really make working in that
taskPane space manageable. 

Again, thank you for your response.

dennis

You are not being very informative.
I have seen this error when the dll files are missing from the bin 
folder, or the IIS server folder is not setup for .Net 2.0.

RE: [mapguide-users] ByteReader Problem

[Jonio, Dennis \(Aviation\)]

Glad to hear it ...

 

I know this is unsolicited but I noticed you were/are using XmlDocument.
Good choice. XPathNavigator works well. Just keep in mind the extra
octet that MS put in front when you serialize out of XmlDocument.

Thanks Dennis.

 

I've tried this, but I'm only getting 8192 bytes read into the byte
buffer. This seems to be the problem mentioned by Kenneth. The Read
method doesn't seem to allow the start location for the read to be set,
so looping until the entire content of the Resource is read into the
buffer doesn't seem to be an option.

 

Presumably somebody must have found a way around this.

I am trying to alter a map definition through the API and cannot get the
contents of the MgByteReader in string format. Here's the code:-

String mapDefinition = "Library://My Folder/Maps/My
Map.MapDefinition"; 
MgResourceIdentifier MapResID = new
MgResourceIdentifier(mapDefinition); 

MgByteReader mapByteRdr =
res.GetResourceContent(MapResID);//res is instantiated Resource Service.


XmlDocument doc = new XmlDocument(); 

doc.LoadXml(mapByteRdr.ToString()); 

LoadXML fails with an error ' Root element is missing'. I can copy the
contents of mapByteRdr from Visual Studio at runtime and it contains
properly formatted XML for the map definition. If I use the ToFile()
method, the resultant file is empty. I cannot see why these two methods
do not return the xml string in the reader. Any help is welcome.

Cheers, 

Keith
