Re: [mapguide-users] Hyperlink not showing

[Kenneth Skovhede, GEOGRAF A/S]

A nice trick is to use an URL starting with javascript:, ea: 
javascript:alert('hello');.
Then the javascript can call any function you have and display the 
options to the user.


You wont get any links active without using the URL Activated for Feature.
You can use the above javascript: trick for the URL.
Tooltips can show embedded html, but disappear when the mouse moves, 
making it hard to use.

I have an attribute in one of my point layers called 'hyperlink'.  When I
select a point in a flexible web layout (i.e., Slate) the selection widget
shows the hyperlink address, but I can not click on the address to advance
to the website.

I know I can use the 'URL Activated for Feature' in the layer editor,
however I may have points that would have multiple hyperlinks to chose from.

I have tried the following in the attributes for the point layer with no
success:

1. www.123.com
2. http://www.123.com
3. a href=http://www.123.com; 123/a

I have MGOS version 2.0.0.2308 installed and am using Autodesk MapGuide
Studio 2008.

Any help would be appreciated.

Re: [mapguide-users] Adding a temporary Layer in MapGuide

[Kenneth Skovhede, GEOGRAF A/S]

In the buffer.aspx, the AddFeatureToCollection(...) function adds the 
feature.

The MgGeometry parameter can be created using the MgGeometryFactory:
http://mapguide.osgeo.org/files/mapguide/docs/2.0/d4/d46/class_mg_geometry_factory.htm

I don't know what happens with the exception, but it has something to do 
with selection,

which you can hopefully ignore.

As I said on my last post, I successfully linked the buffer code to 
the Task Panel item. But there is a problem, when the buffer code is 
executed I get this runtime error:


Buffer Error
An unclassified exception occurred. Exception occurred in method 
new_MgSelection__SWIG_1 at line 649 in file .\MgApi_wrap.cpp


I followed these steps to link the buffer code to the Task Panel:
- In DevGuideSamples\JAVASAMPLES\HELLO_MAP there are TASK_PANE.JSP and 
DISPLAY_SPATIAL_REFERENCE.JSP.
TASK_PANE.JSP is linked to the Task Panel, and it calls 
DISPLAY_SPATIAL_REFERENCE.JSP

- In mapviewerjava there is buffer.jsp
- I copied the buffer.jsp code into the DISPLAY_SPATIAL_REFERENCE.JSP 
file



How can I solve that problem?

You said to insert points instead of the buffer feature. How? Points 
(or a line in a similar task) have coordinates stored on a MySql 
database...

Try looking at the file:

It has a fair amount of comments in it.
You should replace the calls to AddFeatureToCollection, so you insert a

[mapguide-users] SetSpatialFilter and MgFeatureSpatialOperations problem with search

[Maciej Skorczewski]

Hi

my problem is with SetSpatialFilter , in my application user click on 
PARCEL (on map) , and after click on get REGION name application 
should try to search in which REGION (biger surface) is the PARCEL.



what i want to get is:

help image :)
http://img171.imageshack.us/img171/8450/51030812fq1.png

so when user click on small parcel (in grey REGION), first pictures he 
should get ID of big grey REGION.


i you see on second image if parcel is nearly yellow REGION user should 
 get ID ONLY  grey  region 



I try use all method like:

MgFeatureSpatialOperations::Intersects

it is work but i get all REGION who Intersects my parcel (yellow and 
grey  region ), after try another MgFeatureSpatialOperations like:


MgFeatureSpatialOperations::Contains = 0
MgFeatureSpatialOperations::CoveredBy = 8
MgFeatureSpatialOperations::Crosses = 1
MgFeatureSpatialOperations::Disjoint = 2
MgFeatureSpatialOperations::EnvelopeIntersects = 10
MgFeatureSpatialOperations::Equals = 3
MgFeatureSpatialOperations::Inside = 9
MgFeatureSpatialOperations::Intersects = 4
MgFeatureSpatialOperations::Overlaps = 5
MgFeatureSpatialOperations::Touches = 6
MgFeatureSpatialOperations::Within = 7


but get wrong/or none results

That is may procedure
1. user click on map
2. he press button REGION info
3. application use Getselection method to get selected parcel info: 
ID,NAME, and x,y Coordinates

4. I create new polygon (Coordinates come from selected parcel)
5. i use SetSpatialFilter and by iteration on all map layer i  check
what layer is in selected polygon range (REGION).



//my code
$selectedFeatures2=array(); //REGION ID,NAME etc.
//$coords -- come from selected parcel (GetCoordinates())

//generate new polygon from selected parcel
$linearRing = $geometryFactory-CreateLinearRing($coords);
$parcel_polygon = $geometryFactory-CreatePolygon($linearRing, null);
$resourceService=$siteConnection-CreateService(MgServiceType::ResourceService);


///BEGIN layer iteration...on all map layer


$layer = $map-GetLayers()-GetItem($layer_name[$i]);
$resId = new MgResourceIdentifier($layer-GetFeatureSourceId());
$featureGeometry = $layer-GetFeatureGeometryName();
$featureClass = $layer-GetFeatureClassName();
$schemaAndClass = explode(:, $featureClass);
$featureService 
=$siteConnection-CreateService(MgServiceType::FeatureService);

$queryOptions = new MgFeatureQueryOptions();
$queryOptions-SetSpatialFilter($featureGeometry,
$polygon,MgFeatureSpatialOperations::Intersects);


$featureReader = $featureService-SelectFeatures($resId, 
$layer-GetFeatureClassName(), $queryOptions);

while ($featureReader-ReadNext())
{ 
$selectedFeatures2[]=array(layer_name=$featureReader-GetString('Layer'),FeatureId=$featureReader-GetInt32('FeatureId'));

}



///END layer iteration...on all map layer








Can you pleas give me some sample code for this?

Hi Stefan,

I just submitted a change to the trunk version of ajaxmappane.templ that should 
resolve this issue. Take a look at the submission:

http://trac.osgeo.org/mapguide/changeset/3557

You should be able to make the same simple changes to your own version of this

anything.

I tried digitizing a rectangle, and the result was that it was offset only in 
the y axis. I believe this corresponds to the small space that you have between 
the top of the map frame and the top of the map itself. I've seen bugs reported 
about this gap before, but I'm not sure if they've been resolved.

Subject: [mapguide-users] Precision problem viewing map

Hi all,
I am facing a strange and unexpected problem regarding precision of map
and coordinates display. I see that my data is not displayed on the
exact place - there is a shift in Y coordinate. I have a raster layer
with bounding rectangle
Xmin=..., Ymin=7070400, Xmax= Ymax=7071600. But when I move the
mouse pointer at the lower left corner I see Y=7070320 (at scale 1:2000
let say) or similar value, and the difference depends on the scale. If I
zoom down, the difference changes, and at scales close to 1:50 it is ok.
The situation is similar at the upper right corner. I observe exactly
the same effect with all other layers.
I wouldn't care too much about this - even if there is a shift, all
layers are shifted equally, but when I digitize a polygon it is also
shifted. Imagine I digitize a polygon to follow a feature on the raster
image, coordinates are recorded , the feature is added to data source,
but when it is added, due to this shift it appears not where it has been
digitized, but shifted.
I guess you did not understand anything of this, but you can visit

http://www.bgmapguide.com:8008/mapguide/rakvag/main.php

click on draw a new suggestion and try to digitize 2 adjacent polygons
- you will see them overlap
Please be gentle to the server - it is an old tired horse.
And to save some time - all layers and the map are in the same
coordinate system.
This effect is not depending on the browser (tested with FFox 2  3,
Safari and IE) and is not depending on the screen resolution

Re: [mapguide-users] Adding a temporary Layer in MapGuide

[Kenneth Skovhede, GEOGRAF A/S]

The tooltip uses a very narrow selection area,
meaning that you have to be VERY precise to hit it.
At high zoom levels, it is not possible to hit the correct pixel.

You can modify the ajaxmappane.templ file to use a wider search area.
I recommend calculating an area of 10x10 pixels, and then constructing
a polygon that has that size in the current scale.

With those, you can manually pass them to the request, if you use 
the InvokeScript method,

but there may be an easier way.

Thank you for your help!
I'm seeing that the code you posted is very similar to the 
buffer code, however I'm really new to MapGuide, so I hope you 
can help me understanding how to make it work.


I created a Layout, using MapGuide Studio, on which I added a 
new custom command for the Task panel, named Route tracing. 
Therefore I created the route_tracing.jsp file, on which I'm 
trying to use your code (translating it from PHP to JSP) or the 
buffer.jsp code (which is already in JSP).


On both your code and buffer.jsp there is this code:
mapName = GetParameter(request, MAPNAME);
sessionId = GetParameter(request, SESSION);

- The question is: how can I pass the MAPNAME and SESSION values 
to the web page?


The final result should be a web page, which opens when its 
Action Task item is clicked, on which I can select and digit 
some options. After clicking a button the page should get these 
values, and display the map with the calculated additional layer 
on it.




I hope you can help me about that
Cheers
Carmelo

[mapguide-users] Load Layer Definition XML

[wordsy]

Hey Everyone;

Fairly new to MGOS.

Here is what I am trying to do.  

I have a map with many Layers.  One of my requirements is to allow users to
be able to change the layer styles via a web wizard.  The user will be able
to adjust certain styles for line/point/polygon (surface).  Ie font, symbol,
line thickness, color etc.

Already my site allows a user to select the layer they want to change, then
change the styles for a point only.  The changing doesn't seem to be a
problem right now.

The problem I have:

Once a user selects the layer they want to load.  How would I get the layer
and use XML document or XPATH or something to allow the users edit XML
nodes.

Here is my code that checks to see what layer type I have when the user
selects the layer.  I have 3 different user controls (one for line, one for
poly, one for line).  What I really want, is to load the layer and populate
the appropriate controls inside the user control.

 MgSiteConnection conn = InitializeGisWebTier();
string resource = Library://MUNICIPALITIES/ + Municipality +
/2_DATA/ + LayerName + .FeatureSource;

MgResourceService svc =
(MgResourceService)conn.CreateService(MgServiceType.ResourceService );

// Populate some values that we will need.
MgResourceIdentifier resourceId = new
MgResourceIdentifier(resource);  
MgFeatureReader featureReader =
LayerDefinitionFactory.MakeAFeatureReader(conn, resourceId);


// Find out what type of Geometric property the FeatureSource we
uploaded has.
string geometricPropertyType =
LayerDefinitionFactory.GetFeatureSourceGeometricPropertyType(featureReader);

switch (geometricPropertyType)
{
case SURFACE:
// We load the Polygon usercontrol
this.phStylizeLayerControl.Controls.Add(new
PolygonStyleBuilder());
break;
case POINT:
// we load the point usercontrol
//this.phStylizeLayerControl.Controls.Add(new
PointStyleBuilder());
PointStyleBuilder control =
(PointStyleBuilder)LoadControl(~/Pages/Controls/PointStyleBuilder.ascx);
this.phStylizeLayerControl.Controls.Add(control);
txtSymbol.Enabled = true;
txtSymbolSize.Enabled = true;
break;
case CURVE:
// we load the line user control
this.phStylizeLayerControl.Controls.Add(new
LineStyleBuilder());
break;
}

Thanks for any help in advance.

RE: [mapguide-users] SetSelectionXML 'Stack overflow at line 0' errow

Hi Chris,
  I use this code:

objMap = New MgMap(objMGSite)
objMap.Open(objMapId.GetName)
objLayer = objMap.GetLayers.GetItem(strLayer)
objQueryIdOptions = New MgFeatureQueryOptions()
objQueryIdOptions.SetFilter(strFilter)
Dim objFeatureR2 As MgFeatureReader =
objLayer.SelectFeatures(objQueryIdOptions)
Response.Write(br/ObjFeature)
objSelection = New MgSelection(objMap)
objSelection.AddFeatures(objLayer, objFeatureR2, 0)
Dim strXML as String=objSelection.ToXML() 


At the end of ASP.NET function I put the strXML value into as html input box
then I call the Javascript code

..mapFrame.SetSelectionXML(document.XMLinput.value)

Thanks

RE: [mapguide-users] Two maps in the same layout

[Rodolfo Moreno]

Hi Mark, about your question:

- Why would you need to modify any of the viewer files in order to have 2
pages in your map? 
I have modified viewer files because I want to set a themed layer
dynamically in each map in the first time that my application to be loaded. 
My use case is: The theming is placed according to a preference to set by
the user in previous session. Thus the applicacion could show two
preferences on the same map(and the same layout). This is useful when you
want to show comparisons, for example: To compare population 1980 vs 1990
(like a dashboard).

Ivan good sugestion about the iframes, it's better than frameset. However I
would like to do it using FUSION viewer. Is it possible?

Thanks,

RE: [mapguide-users] Two maps in the same layout

[Rodolfo Moreno]

Only for completing my idea about the dynamic theming in the first time:

frame id=viewer1Frame frameborder=no marginwidth=0 marginheight=0
scrolling=no
src=/mapguide/mapviewernet/ajaxviewer.aspx?SESSION=%=sessionId1%WEBLAYOUT=%=webLayout%THEMINGTYPE=1

In this sentence you can see a parameter added called THEMINGTYPE, which is
why I have modified the viewer files. I have not found another way of doing
theming dynamically in the first time. 
I would like to do it without modifying the viewer files and much better if
it is possible to do in FUSION viewer. 

Thanks in advance,

RE: [mapguide-users] Two maps in the same layout

[Jackie Ng]

Sorry, I didn't thoroughly read your original question. So I'll try again.

The main problem here is that you can't initially theme because you don't
have access to the runtime map(s) as the viewer's haven't loaded yet.

What you can do is hook on the viewer's loading process (like so:
http://trac.osgeo.org/mapguide/wiki/CodeSamples/JavaScript/AJAXViewerEventHooking)
and invoke a server-side script that does the theming passing in your map's
name (which will now be available) and any other theming parameters. 

When the theming script has completed, refresh the affected viewer.

Hope that helps.

- Jackie
