Hi, http://trac.osgeo.org/mapguide/wiki/HttpApi With usage of createRuntimeMap, MapGuide can be a good datesource for javascript viewer like OpenLayers.

Re: [mapguide-users] impersonate mapagent to server
Ok i see what you can do building your own mapagent.. But not sure that it
can help me. I don't know how you can impersonte the final MgHttpRequest and
mapserver to use it.
My idea was that the final process ("mapserver.exe" service) know who i am.
So Oracle know who i am.
Basic usage: in a view with "SYS_CONTEXT('USERENV','OS_USER')" col, display
my username in MapGuide Tooltip (right now it show the local system acount
who run mapserver.exe).
Heavy usage: connect Oracle to a VPD and filter shown based on connected
user.
thank you, i learnerd some usefull trick with mapagent

[mapguide-users] Tips : Error connecting AIMS to SQLSERVER
Hi, Here is two tips about connecting MapGuide / Aims through Sql provider: 1) Error listing Data Store : Your username can't connect to all datastore but has public role that give him the right to list all datastore. Don't know why, but MG try to connect all. Save your connection with the credentials but not choosing the datastore, close the editor. Edit it as xml, add this: It should work now. 2) you meet this error when testing connection or try to build a layer : *Feature Source - expected entity name for reference* This one was hard to solve, it's password related! The password i was using contains the character. Since MG use lot of xml, i think the was breaking an xml string. Avoid it. I think other chars can break it but didnt try all :p I didn't try with Oracle, PostGis or other password protected provider, i think it break it too.

[mapguide-users] [ajaxViewer] Digitizer mouseUp problem with IExplorer7 / IE8 (patch included)
When you use the viewer api (DigitizeRectangle...) with IExplorer 7/8, on
mouseUp you're callback function is thrown but the mouse is not well
released.
I explain: the digitizer work, call the callback function, but the mouse
seems to be traped in the mapspace:
when i move the mouse pointer in the legend frame (or other frame if my
viewer is in a frameset) i can see the x/y mouse position of the status bar
been updated.
If i move the pointer over an hyperlink or simply a mapguide toolbar button,
the hover event is not fired.
after one click everything work well again.
On webApplication where i used a custom overviewmap (my overviewmap use the
DigitizeRectangle), the behavior is worst..
i found a trick that could help: after hours on this problem i found that
the bug is in wz_jsgraphic in the clear function. when the shape div has it
innerHtml reseted..
as solution i replaced these digitizer function:
this.InitFeedback = function()
{
var rd = document.getElementById(this.fbDiv).style;
rd.position = absolute;
rd.left = this.fbPos + px;
rd.top = 0px;
rd.width = this.fbW + px;
rd.height = this.fbW + px;
rd.visibility = visible;
rd.clip = rect(0px + this.fbW + px + this.fbH + px +
0px);
}
this.ClearFeedback = function()
{
if(this.fbDiv)
document.getElementById(this.fbDiv).style.visibility = hidden;
if(this.fbShape)
this.fbShape.clear();
}
by
this.InitFeedback = function()
{
if(this.fbShape)
this.fbShape.clear();
var rd = document.getElementById(this.fbDiv).style;
rd.position = absolute;
rd.left = this.fbPos + px;
rd.top = 0px;
rd.width = this.fbW + px;
rd.height = this.fbW + px;
rd.visibility = visible;
rd.clip = rect(0px + this.fbW + px + this.fbH + px +
0px);
}
this.ClearFeedback = function()
{
if(this.fbDiv)
document.getElementById(this.fbDiv).style.visibility = hidden;
}
The div innerhtml is cleared when the digitizer start instead of digitizer
end.
It works for me.
Good luck with digitize!
David

[mapguide-users] [Red Hat 4 MGOs 2.0.1] Raster issue (always raster...)
Hi, We have compiled a MGOS 2.0.1 server on Linux, raster support works, but only with small image I have an aerial photography with tiled tiff : about 70mb each. It don't show nor crash If i compress the tiff (with Autodesk Raster Workshop) at 4mb or less each: MapGuide renders the images. I tried also a single 7mb tiff, don't show. Any idea on how to tweak MapGuide server? Or should i create smaller tiff image?

Re: [mapguide-users] auto-computing map extents
Hi, You can use API to create a mgselection on a layer using an mgquery object whith no filter. Then you can get the MgSelection's MgEnveloppe. As you can't change MapExtent during the runtime (i don't know if it's possible with MGOS 2.0) you will have to create and execut your own ZoomExtent method when the map is loaded Beware of MGselection-GetEnveloppe (i don't remember the syntax), I had a lot of Server Crash. It happen on know polygon but i don't know why (depend on FDO provider? Or altered Oracle database..)

Something like:

Use a featureReader with the MgFeatureQueryOptions
Add the feature's envelope to the outer Envelope

Get zoom extents from the Envelope

For Each Layer
{
Use a featureReader with the MgFeatureQueryOptions
Add the selected feature to the MgSelection
}
Getting the MgSelection enveloppe
It will work, but i don't think it's very optimized with a lot of
Layer/Feature (and it will used at each map load
Re: [mapguide-users] Zoom to Extents
I'm trying do the same thing with the DWF viewer. If you are using the ajax viewer, look at the ZoomSelection() in ajaxmappane.templ file. This method ask the mapagent for the selecion extents, calculate the scale, then use ZoomToView(). But with the DWF viewer, i found no tricks to reproduce the calculteScale() method. Nichols, Mark A. wrote: I see documentation on zooming to an x,y point at a particular scale. What I have is the extents already calculated and I'd like to zoom to that particular extent. I use postgis to get the extents of an object. Results look like county_geometry_extents=631637.01873067,287635.157843,687024.28129651,33 7031.91208509. Can I zoom not to a point, but instead to a set of points that make up the extents.
