RE: [mapguide-users] FDO Gdal raster problem
I'm afraid that this isn't fixed in 2.1 yet either. Haris is working on trying to figure this stuff out for one of his customers, and I'm working closely with him, as I'm seeing the problem too. Between this and the problem of TCP connections becoming exhausted, I'm a bit stuck. If anyone is interested in trying out some .dlls that improve the stability of rasters in 2.0.2 considerably, download the following, make backups of the versions in Server/bin, and then copy them in place (after stopping the server). http://www.jasonbirch.com/temp/mapguide_raster_patch_2.0.2.7z I'll be adding notes on the defects fixed or worked around in these files in the ticket below once Trac starts behaving. http://trac.osgeo.org/mapguide/ticket/462 Jason___ mapguide-users mailing list mapguide-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapguide-users
RE: [mapguide-users] Help with joining tables please
That is correct the view likely won't indicate the key, but as long as the column is available to pick and you select it it should work. I don't think we support the other numeric datatypes for key columns although arguably tinyint and bigint should be candidates. Why float shows up as a key column candidate for the table is odd. Who would use a float as a key? I haven't worked as much with SQL Server 2008 so the behavior of the views is unfamiliar to me.

Yes I use ODBC provider to connect at the MSSQL 2005 tables.
Tomorrow morning I test the computed property from Studio and so I can answer
at your question.

Are you using the ODBC provider then for the connection since you pointed out
the Lat/Lon fields?
It may be a bug with the ODBC provider. I understand your need to code it,
however I was wondering if you tested it with Studio also. If that fails too
it's likely a general bug.

Hi Dave,
if I change this code

objFeatureReader.GetPropertyType("thetooltip"), "thetooltip")
with this one
Dim strTooltipValue as string=GetValueFromReader(objFeatureReader,
objFeatureReader.GetPropertyType("ID"), "ID")
where ID is a property of featuresource I haven't any error so I think that the
problem is the computed property.
Matteo
I would do the following to better debug things.
You should check that the objFeatureReader returned from the SelectFeatures
call is not null before starting the .ReadNext.
As well note that you don't appear to have set the filter either so you will
likely get more than 1 record back from your data.
You might also try the SelectFeatures without adding the computed property, but
instead specify an existing known property and include the filter.
This looks like it should work.

Add a computed property via Studio is not a good solution for my case because I
manage 10 projects with a total of 100 featuresource of this type and this
function will work for all of those
Thanks a lot

What is the data format of the feature source SDF, SHP? It may be a bug.
What if you make a copy of the existing feature source and add the computed
property via Studio does that work?

Hi Dave,

objFeatureReader.GetPropertyType("thetooltip"), "thetooltip")

I would do the following to better debug things.
You should check that the objFeatureReader returned from the SelectFeatures
call is not null before starting the .ReadNext.
As well note that you don't appear to have set the filter either so you will
likely get more than 1 record back from your data.
You might also try the SelectFeatures without adding the computed property, but
instead specify an existing known property and include the filter.
This looks like it should work.

RE: [mapguide-users] Help with joining tables please
Hi Dave, thank you for the suggestions. I am using a single database and trying to join tables within them. I agree that using a View is the best choice, because that also allows me to adjust time zones. The problem I'm having now is MapGuide Studio will NOT display my GPS_LAT and GPS_LON fields when setting up the geometry. Out of 39 columns, only five are selectable. One thing that appears different is for the native table, only two columns are listed as "key" fields and they are not the GPS_LAT/LON columns. My new view has almost all of the columns as a "key" field including the lat/lon columns. How can I move the "key" fields to the selectable x, y columns?

I want to combine a few tables together and have that data available for themeing and viewing. Without attempting to join tables, the data loads without any problem. However, I have not been able to get tables joined. Using normal SQL Server 2008 "inner join tableB on tableA.location = tableB.location" is what I'm trying to do. Using the Autdesk Mapguide Studio, I click through, set up my joining tables exactly as I would in SQL. In the layer definition editor, I see the new attributes. Before doing anything else, I export the layer as XML and test my map. The map viewer doesn't stop showing the busy icon, the legend labels become question marks (?) and no data ever loads. If I disable the layer, all the other layers show quickly. I've tried using the same database connection, a different database connection, and a SDF imported from a shapefile. No method appears to work for me. Is there a proper way of setting up joining tables? Should I learn the XML syntax and do it manually?

Can you show a larger block of code? It seems like something else is wrong
after you add the computed property to the QueryFeatureOptions object.

Re: [mapguide-users] Modify mapdefinition in a layout
Hi alucas,
you have very luck because it seems that i have problem in my C# code or
perhaps in my configuration of mapguide server.
Hi
I provide the end user with a link to my special page (see the code1). In that
page i redirect to the MapGuide viewer files (Response.Redirect).
code1:
The fonction SetLayout Map modify the mapdefinition in my layout. See image
here :
The problem : the layout is not modify and i have this message : An exception
occurred in the XML parser.
Have you an idea ?
Thanks
Hello,
this code works well for me (PHP):
function changeWebLayout($rs, $WebLayoutResId, $newMapResId, $s)
{
try
{
// Obtenemos el contenido del WebLayout en XML
$byteReader = $rs->GetResourceContent($WebLayoutResId);
$xml = $byteReader->ToString();
$doc = DOMDocument::loadXML($xml);
// Accedemos al nodo que queremos
$wl = $doc->getElementsByTagName("ResourceId");
$mapResIdNode = $wl->item(0);
$mapResIdNode->nodeValue = $newMapResId->ToString();
$strXML = $doc->saveXML();
//header('content-type: text/xml');
$byteSource = new MgByteSource($strXML, strlen($strXML));
$byteSource->SetMimeType(MgMimeType::Xml);
// Modificamos el repositorio
$rs->SetResource($WebLayoutResId,
$byteSource->GetReader(), null);
}
catch (MgException $e)
{
echo $e->GetDetails();
}

RE: [mapguide-users] What is %24CurrentSelection???
Hi Achectl,
It is encouraging that it got that far before it failed this time. In the code
below, you've commented out the original call to get the selection from the
map, and instead retrieve it from the $selectionXml parameter. I don't see this
defined anywhere, which is presumably why it fails.
Try changing this:
// Retrieve the selection
$selection = new MgSelection($map, $selectionXml);
//$selection = new MgSelection();
//$selection->Open($resourceService, $mapName);
To this:
// Retrieve the selection
$selection = new MgSelection();
$selection->Open($resourceService, $mapName);
$selectionXml = $selection->ToXml();
Chris.

Hi Chris,
I've tried to follow your script and try to modify a little of date.php as
below:
Open($user);

$resourceService = $siteConnection->CreateService(0);
// Retrieve the selection
$selection = new MgSelection($map, $selectionXml);
//$selection = new MgSelection();
//$selection->Open($resourceService, $mapName);

catch(MgException $e)

echo "" . $e->GetMessage() . "";
echo "" . $e->GetDetails() . "";

function GetParameters($params)

$mapName = $params['MAPNAME'];
$sessionId = $params['SESSION'];
$ID = $params['ID'];
$Area = $params['Area'];

echo $ID;
echo $Area;
}
function GetRequestParameters()
{
if($_SERVER['REQUEST_METHOD'] == "POST")
GetParameters($_POST);
else
GetParameters($_GET);

?>
After click the invokeURL command of the fusion layout, it prompts the error
"Default49cb4916a1dfe$CurrentSelection$CurrentSelectionAn unclassified
exception occurred.An unclassified exception occurred. Exception occurred in
method new_MgSelection at line 12308 in file .\MgApi_wrap.cpp" of the new
date.php window.
The $ID & $Area is the key of the invokeURL.js. It seems that the proper value
still can't to find! I think it should be something missing of the date.php.
Thanks
Achectl
If your date.php file is on a separate server, it seems like a good idea to
save the sample code in a local file, as you've done, and then make that script
issue a subsequent request to date.php.
It looks like the SESSION parameter is not getting sent to your script. It
could be a case issue - it might get sent as lowercase 'session' instead. Are
you able to use Fiddler or Firebug to determine which parameters are actually
getting sent to your script? I also remember seeing a defect where the
parameters got sent twice, which caused problems.
If your InvokeUrl.js (in the fusion/widgets folder) contains a section like
this:
execute : function() {
var url = this.sBaseUrl;
//add in other parameters to the url here
var map = this.getMap();
var params = [];
params.push('LOCALE='+Fusion.locale);
params.push('SESSION='+map.getSessionID());
params.push('MAPNAME='+map.getMapName());
params = params.concat(this.additionalParameters);
try changing it to:
execute : function() {
var url = this.sBaseUrl;
//add in other parameters to the url here
var map = this.getMap();
var taskPaneTarget = Fusion.getWidgetById(this.sTarget);
var params = [];
if ( taskPaneTarget == null ) {
params.push('LOCALE='+Fusion.locale);
params.push('SESSION='+map.getSessionID());
params.push('MAPNAME='+map.getMapName());
}
params = params.concat(this.additionalParameters);
An alternative approach would be to fix the InvokeUrl.js file so that it
handles the $CurrentSelection variable correctly, but that would require a bit
of figuring out.
Chris.

another one after modify the Map id ( http://patxi.mayol.free.fr/test_after.xml

You can see my code here : http://patxi.mayol.free.fr/sample3.asp

Even if you don't have any xsd files in c:\temp, you should be able to
open the xml document using Internet Explorer (just drag it into it).
Have you tried to not change the xml, and just save it back to MapGuide
after reading it?
(In your code, just comment out the part that writes the new Map id into
the xml.)

Hi Dave,

So I'm guessing in your code you have something like:
result=mgFeatQueryOptions.AddComputedProperty(computedPropAlias, computedProp);
So what if you add a debug statement after it to do something like echo the
following:
Response.Write("Computed Property index: " + result.ToString());
An alternative to trying to do this in code might be to edit the feature source
and add the computed property there. Create your layer using the extended
feature class and in your code you can just select this property without having
to do the computed property bit, but if there is something wrong with the
expression you have maybe that is causing the computed property to actually get
added. I wouldn't call it tooltip by the way as that seems too much like a
keyword. I would call it theToolTip or something to be safe.

Using the Autdesk Mapguide Studio, I click through, set up my joining tables exactly as I would in SQL. In the layer definition editor, I see the new attributes.

If I disable the layer, all the other layers show quickly. I've tried using the same database connection, a different database connection, and a SDF imported from a shapefile. No method appears to work for me. Is there a proper way of setting up joining tables? Should I learn the XML syntax and do it manually?

params.push('SESSION='+map.getSessionID());
params.push('MAPNAME='+map.getMapName());
params = params.concat(this.additionalParameters);
try changing it to:
execute : function() {
var url = this.sBaseUrl;
//add in other parameters to the url here
var map = this.getMap();
var taskPaneTarget = Fusion.getWidgetById(this.sTarget);
var params = [];
if ( taskPaneTarget == null ) {
params.push('LOCALE='+Fusion.locale);
params.push('SESSION='+map.getSessionID());
params.push('MAPNAME='+map.getMapName());
}
params = params.concat(this.additionalParameters);
An alternative approach would be to fix the InvokeUrl.js file so that it
handles the $CurrentSelection variable correctly, but that would require a bit
of figuring out.
Chris.
