And on client side, something like this (this is only a piece):
function retrieveMap()
{
var layersString = getLayers();
baseUrl = document.getElementById("baseUrl").value;
imgext = document.getElementById("imgext").value; //existing inline
image
imgbox = document.getElementById("imgbox").value; //setted by dbox
imgxy = document.getElementById("imgxy").value; //setted by dbox
//build url
queryString = baseUrl + layersString + "&mode=browse" + zoomStr
+"&imgext=" + imgext + "&imgbox=" + imgbox + "&imgxy=" + imgxy;
if(jsDebug == 1) alert(queryString);
mapsrvNet.AjaxMethods.getMap(queryString, retrieveMapImage_callback);
}
function retrieveMapImage_callback(res)
{
if(jsDebug == 1) alert("\nres.error: " + res.error +"\nres.value:
"+res.value+"\nType of res.value: "+typeof(res.value));
try {
if(typeof(res.value) == 'object' && res.error == null) {
//immagini
imgMapOff.src = res.value.mapImgUrl;
imgRefOff.src = res.value.referenceMap;
imgScalebarOff.src = res.value.scalebar;
if(jsDebug == 1)
alert(imgMapOff.src+"\n"+imgRefOff.src+"\n"+imgScalebarOff.src);
//hidden variables
document.getElementById("mapwidth").value = res.value.mapwidth;
document.getElementById("mapheight").value =
res.value.mapheight;
document.getElementById("imgxy").value = res.value.imgxy;
document.getElementById("imgext").value = res.value.imgext;
document.getElementById("legend").innerHTML = res.value.legend;
document.getElementById("referenceMap").value =
res.value.referenceMap;
if(jsDebug == 1) alert(res.value.legend);
setTimeout("updateImg()",swapMapImageTime);
} else {
throw res.error.toString();
}
} catch (exception) {
this.status = "----------- PROBLEMS RETRIEVING MAP ! -------------";
if(jsDebug == 1) { alert(exception); }
}
}
You could work in similar ways for query mode, etc.
This was build using AjaxPro
(http://www.codeplex.com/Wiki/View.aspx?ProjectName=AjaxProStarterKit).
Obviously this is only one possible way to work with MapserverCGI.

2006/7/27, rock well <[EMAIL PROTECTED]>:
Hello all, i am trying to generate a map by requesting the map server
using
like a proxy call to the server. I found this asp script in
http://mapserver.gis.umn.edu/docs/howto/wms_server which
does the same, when i used the same script in asp.net i found that .net
doesnt support xmlhttp, so i registered the required dlls for .net to
support xmlhttp, but still the script doesnt give me any output .... Are
there any changes to be made in this script to make it work in
asp.net ...
well i am sorry if this post is unclear, i could provide with more
information if you need ..
Thanks for your effort and time .....
