[mapguide-users] Tooltip Issues in Internet Explorer

Fri Jun 2 18:46:35 EDT 2006

Andy,

The fact that it works in Studio is puzzling as Studio uses IE for the
previews. It's then a side-effect with IE as a standalone browser.

I'll look into this problem.

It also works perfectly well in the Studio preview window, so I don't
think it's the way we are referencing the images.  My implementation is
very similar to yours and my referenced .aspx page returns an image
programmatically via Response.ContentType = "image/jpeg";  In IE, if I
hold my mouse over the feature for long enough, it might flash 3 or 4
times (sometimes seeing the returned image flash in the contents as
well) and then it settles down and displays.  But most of the time it
just flashes.  I can tell that each one of those flashes the web
surround is calling the embedded page over and over, however.  Like I
said, I think this will be easy for Autodesk to replicate by just
plugging in the below <img> tag into a layer tooltip and loading the map
in IE.

Yep...Works great in Firefox.   So you see the IE issue?  Just flashes.
Maybe it's with the way they are pushing out the image.

I'm going to try one of my .NET pages that pushes out an image.
Hopefully, that will work better.

Thanks Andy.

Juan,

By removing the double-quotes around the URL, it works fine.  I just
tried it by assigning: <img
src=http://www3.fdle.state.fl.us/sexual_predators/GetImage.asp?fin=25109
5 border=0 width=52 height=59>' border=0 width=52 height=59>.  to one of
my layers tooltip so it displays that for every object.  I still see the
Internet Explorer weirdness, however.  At least it should make testing
that problem easy for Autodesk ...........

Andy:

So you reference a page like me when trying to bring the images...

In my tool tip, I have'<img
src="http://www3.fdle.state.fl.us/sexual_predators/GetImage.asp?fin=2510
95" border=0 width=52 height=59>'

 border=0 width=52 height=59>'

This should bring back the image, but it's not.   Can you pass along how
you are putting the code in the tool tip?   Maybe I'm doing something
wrong.    You're using Enterprise version of Mapguide OS?

Juan,

Yes, the image are on that server and are rendered from the full-size
images on-the-fly to a .NET thumbnail image.  This image is created by
an ASP.NET page that the tooltip references while passing the parcel ID.
I use the exact same page calls in Google Maps and Google Earth and it
works incredibly well.  I am actually amazed at how fast .NET is at this
on-the-fly image processing.  You can see the Google Earth
implementation here:
http://mapguide.spatialgis.com/mapguide/GoogleEarthDemo/.  I don't have
all of the images for the County loaded (40 GB worth) on to the server
yet, but will by Monday.  For now, open this placemark file after
opening the above link in Google Earth.

Regarding your other question, no, I have not seen the browser freeze up
when accessing this application.  It could be that you happened to be
browsing when the MapGuide service was restarted and you lost your
session.  I restart it via a scheduled task every two hours due to
stability issues discussed in the past.  It's not pretty, but it makes
sure that the server is usually running when people try to access it.

This goes back to a post that I had earlier.   You are referencing an
image on a server somewhere, correct?  I have this working great too,
but in IE the tool tip acts erratically.  

I have images that I stream from the database or other locations.   I
wish I could take this a bit further and place the streamed data into
the tool tip.   Hopefully, in upcoming releases this will be supported
and the performance will be OK.

I have a Google map that works perfectly for streaming images in the
tool tip information for the markers.   It utilizes XSL to format tool
tip information.

I have custom tooltips built in a map and as part of that tooltip, an
external page is called that generates an image.  This works extremely
well in Firefox as well as the Studio preview window.  However, in
Internet Explorer I get very odd, inconsistent results.  These tooltips
sometimes work correctly, but most of the time, as you hover over a
parcel, it makes repeated calls to the server and never "holds still".
This looks an issue with AJAX handling between the two browsers.

Here is a link to try first in Firefox and then in IE:

%3a%2f%2fSpokaneMaps%2fWeb+Layouts%2ftest.WebLayout&USERNAME=Anonymous
<http://mapguide.spatialgis.com/mapguide/mapviewerajax/?WEBLAYOUT=Librar
y%3a%2f%2fSpokaneMaps%2fWeb+Layouts%2ftest.WebLayout&USERNAME=Anonymous>

Any help on this from Autodesk would be greatly appreciated.  Thank you.
