[svg-developers] how to detect end of manual panning in ASV?
Is there any reasonable way to detect the end of panning (left mouse
button goes up while the cursor is a 'hand')?
I ve got some text I have to put into the SVG every time the position
of svg changes. But for performance reasons I don't want to call this
function while panning, but only once every time the user stops
panning (i.e. mouse button goes up and ASV was in panning mode, i.e.
you can see a 'hand' cursor) - then I would call my text-placing function.
I tested with mouse-up and it doesn't work at all. So finally I use
mouseHookEx API function but it makes some troubles in my app, so I
would like to avoid it.
From the other hand I wouldn't like to use my own panning
('mousedown', 'mousemove', 'mouseup' handling and changing translate
of the svg), since we have a strong requirement on how the cursor
should look like.
Using standard ASV panning I've got a warranty I have a 'hand'-cursor.
Is there any way to handle cursors in ASV3.02 (even on the system
level), then it could be an alternative to me to use this cursor
handling with my own panning.
cheers

[svg-developers] Re: Executing Java/C# server method from svg
It would be best to make your server application a HTTP server, preferably on port 80, if you want your app to be usable anywhere as that way it will go through proxies, firewalls etc. I think it is much easier in SVG to communicate via HTTP anyway, and a simple HTTP server is very easy to write. - To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click edit my membership Yahoo!

[svg-developers] Re: Executing Java/C# server method from svg
This may be a stupid question as I am not that familiar with HTTP servers, but how do I do this? I was planning on writing a C# application which connects to another already-written C# application which houses a databus and connects to a database. There are specific methods to connect to this C# databus app and specific calls you have to make to retrieve data. Will I still write a C# app and somehow put that within the HTTP server or would I do something different in a different language or tool? Sounds like the getURL/postURL method only works with HTTP servers, correct? Thanks for your help.

[svg-developers] Re: Executing Java/C# server method from svg
More basic questions. I am a Java/C# developer with not much web experience. I don't know anything about ASP or JSP. 1) I'm assuming that ASP.NET use C# (similar to JSP using Java)? 2) I am using IIS web server and the client's requirement is to stick with this. Do I need an app server to go along with this (such as JBoss) or extension or something in order for servlets to run? Or will my asp just run within IIS alone? 3) Would I then use getURL/postURL from my svg/Javascript to execute the asp class to retrieve my data? Thanks a ton!! I'm a newbie to web development.

RE: [svg-developers] MID/MIF to SVG conversion
Hi, MID/MIF is a very simple ASCII interchange format used by MapInfo. I believe MapInfo exports svg. Alternatively it would not be much of a project to simply write a translator that would take the mif to svg. Adding mid attributes requires a decision. You can: A. ignore attributes B. add a single attribute in the svg id C. add multiple attributes as custom namespace attributes D. put the attributes in a SQL database like MySQL, PostgreSQL and link the records to your svg through the id attribute. E. Or you can turn them into a GIS system and import both vectors and attributes to PostGIS using something like the ogr translation utilities: http://www.remotesensing.org:16080/ogr/ogr_formats.html This gives you the most flexibility of exporting to svg using geospatial queries, but you have to be able to write your own query result exporter.

Re: [svg-developers] Re: Executing Java/C# server method from svg
I'd posted some information on this a while back. What I'm doing is this: Write COM component which you can embed in a parent HTML doc. Embed the SVG doc. in this HTML doc. In you event handler you can refer to the COM component interface methods as: parent.COMCompID.SendEvent(evt) where COMCompID is the id of the embedded COM object;SendEvent(evt) is the COM interface method You can embed a C# component too - I believe IE supports that. But, I found it easier to use a COM component and then use a C# app. to process the SVGDocument directly to do whatever you need to do - you can get you data updates into your C# app. and process the data and accordingly update the SVG document with C# routines i.e. on the SVG DOM - based on the previously received SVGDocument object.

Use getURL. Your HttpHandler will to map to a URL something like: http://yourserver/YourHandler?timestamp=2005-02-01T12:15:00dataset=XXX ASP.Net runs under IIS and exposes your handlers this way. You can return data as text, XML, whatever. I would suggest moving the discussion to the Microsoft ASP.NET newsgroups, where you'll be able to get more guidance on building your handler.
