[Mapserver-users] RE: [Summary - MapServer and ASP.Net

[Ross Smith]

Hi all,

As promised I would provide a summary of the responses, I received regarding
MapServer and ASP.Net development.  I would like to thanks all those who
responded and hope that this information is useful to you as well.

----------

Yes, you can use ASP.net or any other programming language to work with
MapServer CGI. What you would preferrably do is write your own ASP.net
'wrapper' or class to build the requests to and parse the responses from
MapServer.

Of course you can also just build requests on the fly but for code
maintenance it would be best to put things together a bit.

A sample of a .net wrapper can be found at http://www.iter.dk/

Best regards,

 My company is in the process of building an ASP.NET-based app with
mapserver.  So far it is working just great!  We have an aspx page that sits
in front of the mapserver and translates the incoming requests into
mapserver-specific requests.  The aspx page then returns the
mapserver-generated image to the client (or the error XML if an error
occurs).

Depending on your needs, you may be able to simply use mapserv cgi for pages
that require a map, and use ASP for your other pages (e.g. pages that access
a relational database). This is what I do.

I have also used aspexec from http://www.serverobjects.com/products.htm
which allows ASP to execute mapserv.exe

And a similar approach is discussed at:
http://mapserver.gis.umn.edu/doc40/wms-server-howto.html#onlineresourceurl

If you search the archives, Ed McNierney has some nice examples of using
asp. You can use Google to search with syntax like:
    site:gis.umn.edu ASP Ed McNierney

Its pretty simple to use mapserver from asp.net.
Here is how I do it.

I setup mapserver normally. Then I make cgi calls to the proper url strings
set up through the program's logic. I then set the url property of an
imagebutton to this url. The nice thing about setting the url of an
imagebutton to the cgi call is that no temporary images are created.
If you need a finer level of control then you could dynamically create the
map files.  I've done this in cases where I need to display lots of data and
need more control than is possible through a url string. 

And of course you could put all this into a nice asp.net wrapper.

I have some source available on request.

Hope this makes sense,

Nelson

Hi everyone,

I searched the archives because I assume this question has been asked a lot
but I could not locate any conclusive answers.

Can ASP.Net be used to design websites and communicate with the MapServer
cgi exe?  Any assistance would be useful, we are an ASP shop looking to move
into the MapServer world and we would like to leverage our ASP knowledge.

Thanks in advance, I will summarize the responses for everyone.

Ross
