<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I’ve painfully found out through
many trials that the RenderingService.QueryFeatures object in Mapguide API only
allows you to select Map Features that are Selectable at current Scale.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>And that the object Highlights only Show
if the Object is Currently Turned On. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>(Making things worse This is the Only Java
Class that Bombs in Coldfusion, it works flawlessy when No objects can be
selected and returns a blank Schema, but if something can be it Crashes)<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I understand the coding for this and the
reasons….for 90% of Applications<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>However We Have several that are used to
being able to see selections in ArcIMS of Objects that are not Available at the
current Scale or turned on in our Application.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>We would really like to move many of them
over to Mapguide Since they would prefer it. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Example: Searching for 80+ acre parcels
through an entire County from a county wide view…or finding soils
underneath an object without having to turn the themed soils layer on etc.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'> I
would really like to talk with someone about the source code and if this can be
accomplished. The Pin Thing is not what we’re after.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I’ve managed to go down the Feature
Source Path…and Got to this Point : MgGeometryFactory.CreateMultiGeometry(MgGeometryCollection)
: Which is a collection of Objects under the Selection Geometry of Objects on
their Layer filter…i.e. on ParcelCounty1Layer and ParcelCounty2 Layer<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Now I could try to convert this into a
Layer and select it, or theme the layer to look like a selection…but it
sort of defeats allot of the other well coded stuff already in the product.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I sort of wish there were a flag in the RenderingService.QueryFeatures
for True-Allowing Selections On objects not available by scale False-The OldWay
or vice versa<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>And a flag in the Map Renderer that tells
it where to place the Selection Highlight T-Independent of the Layer the
Selection is On(maybe even creating a layer called selection) or F-Tied to the
Layer so if The layer is off, the selection doesn’t show (The current
Method)…<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>…Is this even Plausible? If So it
could be just an optional Flag with the default set to the old way of doing
things so no Apple Carts are upset….I can give Dozens of real world
examples for why this would be a Valid Project to tackle…Unfortunately I
don’t Code in C, I’m really just a web programmer and get Lost in
the Open Source Root code, or I’d try this myself….but that also
wouldn’t make it a part of the permanent API either.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Can anyone tell me if this is possible or
show me a way to emulate this in any code?<o:p></o:p></span></font></p>

description or see a live example of what I’m trying to do we can webex…just
email me and let me know…I could really use the help…or at least to
be told If it just can’t be done in the API or by me using the existing
API.<o:p></o:p></span></font></p>
