I'd still like to see if there are options for improvement of raster resizing quality, even at the expense of performance. A colleague pointed me towards a non-MGOS web GIS, and the raster quality is impeccable: http://www.essexwalks.com/osmap.html?f=tollesburywick.gpx Compare this to our MGOS: http://maps.nnpa.org.uk There are often real issues with legibility of text.

Hi Neil I have followed the instructions from the second link you quoted on several occasions. I find I usually make one or two errors, and it takes a while to get it working, but it absolutely does work. From memory, that example passes variables to the task frame, so you have to specify an initial script there, using Maestro or Studio, which handles the passed in variables, and then manipulates the map frame accordingly. Is that the kind of thing you are trying to achieve?

Well, the following seems to get rid of caching:
header("Expires: 0");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("cache-control: no-store, no-cache, must-revalidate");

But this seems like overkill. Does anyone have definitive information on
best practice for eliminating caching of xmlhttp requests?

[mapguide-users] Re: Viewer API GetLayer() and base layers
That's the page Praveen pointed me towards, and which I was trying to use as a model. However, the two events it shows you how to hook into are the completion of the loading of the map, and OnSelectionChaged. I need to hook into RequestMap(), which is a function, not an event of any kind, as far as my limited understanding tells me. Unless someone can give me a technique to achieve that, I'll go back to hacking the original function, and am aware of the problem of losing that customization when upgrading MapGuide. One other issue I have is caching of my xmlhttp request. I can work around this by adding a random parameter to the query, but realize this is a hack. I am now experimenting with adding cache control headers on the server side. Does anyone know of the best way to achieve this (fully cross-browser compatible)?

[mapguide-users] Re: Viewer API GetLayer() and base layers
Thanks for that information, Praveen, but I cannot get it to hook onto the right event properly, and I'm beyond the limit of my Javascript knowledge here. ajaxmappane.templ has the function RequestMap() which was where I placed my code, and which worked. However, I can see no corresponding OnRequestMap onto which I could hook my function. RequestMap always seems to be called directly, rather than being assigned as a variable, so I cannot copy it and append my function. Or I might be totally misunderstanding how this all works. Can anyone else tell me if there is a way to hook my own function onto the RequestMap() function without hacking the original function itself?

Hi Praveen Many thanks for the pointers. I've managed to get something working without AJAX, but with your instructions, I'll try to implement it in AJAX (which I've never coded before). A final question (hopefully) - how can I trigger this function only when either any layer visiblity changes, or the map zoom level changes? Do I have to hack the viewer templates to add onclick() handlers to the icons/buttons, or are there existing event handlers which I can hook into? At the moment, I'm just having to call the function repeatedly, which results in an obvious repeated request from the browser (ie the status bar progress bar keeps appearing when the request is made, and the IE tab icon keeps changing to the spinning circle).

To get back to your original question, from what I can see, your code will set every option as "selected". But which item do you want to be selected? That list is generated before any user interaction, so which option should be selected? Once the user chooses one option, you can get at it via: inputName.selectedIndex - this gives the numerical index of the item selected inputName[inputName.selectedIndex].value - this gives the value of the item selected I hope this answers your question.

Error: Out of memory in NsSAX2Reader parse File: ..\src\dbxml\nodeStore\NsSAX2Reader.cpp Line: 346 Exception occurred in method MgResourceDefinitionManager.ValidateDocument at line 429 in file d:\buildforgeprojects\mapguide_open_source_v2.0\build_27.16\mgdev\server\src\services\resource\ResourceDefinitionManager.cpp MGOS2.0 (might be 2.01, not sure - how do I check?) W2K3 SP2, IIS, PHP Xeon 2.8GHz, 3.37 GB System disk 50GB (30GB free) - MGOS installed on this volume Data disk 225GB (218GB free) - MGOS repository on this volume No other apps running on this box I don't know how to reproduce the error - as I say, it just seemed to be consistently displaying this morning. Stopping the MGOS service failed (Error 1053: The service did not respond to the start or control request in a timely fashion). A reboot of the box brought it back to life. Has anyone seen this problem (a search of this list brings back an MGOS1.0 instance)? If so, is there a solution, or at least any idea what the cause might be?

So you see the same initial view as in IE7? How about if you zoom in a few times? The map should always have raster tiles (or vector if you zoom in a long way) underneath any of our vector data, unless you go somewhat outside the main boundary polygon. In other words, if you are seeing a white background, but you are within that polygon, that is wrong: there should be base mapping of some kind visible at all zooms. To simplify matters for testing purposes, turn off the "Local Development Framework Map" layer group. All you should then see is our boundary over the base mapping. Base mapping of some kind should always be visible within that polygon. For me in FF3, it is not at the initial view, nor at many other views/zooms. In IE7, it is always there. zspitzer wrote: > > just on the initial load i got the following error > > Error: reqParams is not defined > [snip] > > also > > Error: parent.InMeasure is not a function > [snip] > I found those too, subsequently. I don't know what is causing that. I have manually patched ajaxmappane.templ as per instructions in an earlier thread (changing from POST to GET in RequestMap(), SetSelection(), ZoomSelection(), and RequestHyperLinkData()) in order to get it working in FF3. I noticed in addition that some code was in a different location in the patched version of RequestHyperLinkData(), so I moved it. Has that got rid of the Javascript error? Looks like it might have done. It hasn't fixed the missing rasters, though.

I hadn't realized there were patched binaries too (MapAgent.exe and isapi_MapAgent.dll).

[mapguide-users] Firefox 3 intermittent raster display
Hello Compare IE7/WinXP and FF3/WinXP display of: http://maps.northumberlandnationalpark.org.uk/ IE7 works correctly. FF3 fails to display rasters on many occasions (including the initial view). Zooming will sometimes bring back the rasters, and sometimes even panning will cause them to appear. I have not determined if the precise same zoom/coordinates will always give the same results as far as the display of rasters goes, or whether it is truly intermittent. Can anyone help with this?

Hi Jason Any pointers on how to implement PNG8 or JPG for AJAX? Also, can non-tiled maps be rendered like this too?

[mapguide-users] Partial polygons closed at map viewer edges
Hello When viewing a polygon in MGOS, if one is zoomed in so that some of the polygon is off-screen, MGOS clips the border along the edges of the viewer. To see what I mean, see: http://maps.northumberlandnationalpark.org.uk:443/ http://maps.northumberlandnationalpark.org.uk:443/ Zoom in within the navy line which is our boundary, and see its behaviour once some of the line is off-screen: it runs along the edge of the map, despite the fact that the true border is not there, but off-screen. Is there any reason for this behaviour? To me, it represents inaccurate rendering of data.

Re: [mapguide-users] FF 3 ...AJAX viewer does not load map
That works to a certain extent. The map (and legend) now loads, but my
rasters do not always show up, and sometimes I cannot zoom. I believe the
page can be seen from the outside world for anyone who wishes to test (but
please bear in mind that it is still in development, so changes are
ongoing):

If I execute ZoomToScale() immediately after ExecuteMapAction(10), the zoom occurs before the zoom to selection happens. I've read several threads discussing how to detect when the map has fully loaded, but I cannot get them to work. Can someone tell me how to achieve this (from the scriptFrame), so that I can delay ZoomToScale() until ExecuteMapAction(10) has finished? Thanks again Tom PS Given my actual requirements, simply preventing the user from zooming in too far - setting a threshhold - for the entire application would do the job, but I cannot see how to do that anywhere.

I am using ExecuteMapAction to zoom to a selection, but when the selection is a point object, the viewer is zoomed in so far that there is no context visible, and one has to zoom out a long way before one can see any other features. I therefore simply wanted to change the scale of the map after zooming to the selection. Kenneth Skovhede, GEOGRAF A/S wrote: > > Javascript is case sensitive, you must use GetLegendCtrl(), not > getLegendCtrl(). > My error - apologies. There is now no error thrown, so presumably the method is being called successfully. However, what on earth does it actually do? What, in real terms, does it mean to change the scale of the legend? I assumed that SetScale() was simply an easy way to change the scale of the map, without having to bother with the coordinates, but plainly this is not the case. Thanks for all your help, though. The method you described works perfectly for me.

This works: > mapFrame.ZoomToView(mapFrame.GetCenter().X, mapFrame.GetCenter().Y, scale) Brilliant! Still, in the spirit of understanding things fully, how does one proceed using the method you just described?

Hello all Just to confirm, map also fails to load in FF3 on WinXP SP3, (MGOS on W2K3 IIS, PHP): http://maps.northumberlandnationalpark.org.uk:443/ Also, layers which are set not to appear in the legend appear initially, labelled with '?' as they do in IE7. However, they do not subsequently disappear, as they do in IE7. Hope this helps, as this is obviously extremely important.
