Re: [mapguide-users] Fusion Map Problem

[Paul Spencer]

Hi Scott,

was the problem purely a browser caching problem?  I have tried to  
set up the ajax requests to be not cached by the browser regardless  
of the client configuration so I am interested to know if it works or  
not (I typically run my browsers with caching turned off so it is  
hard for me to tell sometimes if this type of thing has stopped  
working or not)


Cheers

Paul

It sounds like it might be caching the XmlHttpRequest to load the web
layout.  Have you tried it in FireFox?  Do you have FireBug
installed?  If yes, you can look at the actual requests as the load
the web layout from the server and perhaps get a clue as to what is
going on.  If you have a public url that I can access, I might be
able to debug further.  Feel free to email me directly if you don't
want the URL on the list.

Re: [mapguide-users] ByteReader Problem

[Kenneth, GEOGRAF A/S]

The only way around it, that I have found, is to copy/paste code like this:

System.IO.MemoryStream ms = new System.IO.MemoryStream();
byte[] buf = new byte[8*1024];
int read = 1;
while(read != 0)
{
   read = mapByteRdr.Read(buf, buf.length);
 ms.Write(buf, 0, read);
}

//ms now contains the stream

Regards, Kenneth, GEOGRAF A/S

I've tried this, but I'm only getting 8192 bytes read into the byte 
buffer. This seems to be the problem mentioned by Kenneth. The Read 
method doesn't seem to allow the start location for the read to be 
set, so looping until the entire content of the Resource is read into 
the buffer doesn't seem to be an option.

This is what I use in real life ... I did not understand.  I was
illustrating the 8K thingee. It caught me to.  

   

 string lib_layer_definition =
resourceService.GetResourceContent(resId).ToString();

 byte[] layerDefinition = new byte[lib_layer_definition.Length];

 int byteCount = Encoding.UTF8.GetBytes(lib_layer_definition, 0,

The "ToString()" is not implemented, and thus returns "MgByteReader",
which you cannot use as an XML document.

The MgByteReader is very volatile and fragile, when you try to debug it
with VS.
Any attempt to pass the byte reader to a function (as a parameter) will
clear the stream.
You cannot read more than 8kb out of the stream in a single Read()
operation, making it a royal pain to use the MgByteReader.

I have seen others using an MgByteSink, but I have yet to try that.

[mapguide-users] Missing Coordinate Systems

[Kenneth, GEOGRAF A/S]

On multiple installations of MapGuide OS 1.2 RC2, there are no 
coordinate systems installed.


If I access the http:///mapguide/mapagent/index.htm, choose 
Coordinate System and EnumerateCategories i get:


Arbitrary X-Y Coordinate 
Systems


Trying the same on the "Live Application Gallery servers gives:"

Arbitrary X-Y Coordinate 
SystemsEPSGWorld/Continental

The latter is the desired result.
For any server, the "GetBaseLibrary" call returns: "PROJ4 Coordinate 
System Library"


I can see no errors in any of the log files.
It might be related to  ticket 209, 
http://trac.osgeo.org/mapguide/ticket/209.


Tracking it, reveals that a registry entry 
"HKLM\SOFTWARE\MapGuideOpenSource\CoordinateSystem" specifies:

C:\Program Files\MapGuideOpenSource\WebServerExtensions\www\nad
Where the PROJ_LIB specifies:
PROJ_LIB=C:\Program Files\MapGuideOpenSource\Server\nad

I have no idea where each entry comes from, as both machines have had 
1.1 installed.

However, the "categories.txt" is NOT located in
C:\Program Files\MapGuideOpenSource\Server\nad
but can be copied from:
C:\Program Files\MapGuideOpenSource\Server\bin

Copying the file makes the coordinate categories appear.
