Redlining error

[Marius_360]

Hi

I need to develop a redlining application for a client using VB.Net and JavaScript.
I converted the demo code available, but get stuck with the “featureService.CreateFeatureSource” command, it gives me a “Objects of type 'OSGeo.MapGuide.MgService' do not have such a member” error

How do you construct the featureService variable?

You should do something like:

Dim featureService as MgFeatureService  =
connection.CreateService(MgServiceType.FeatureService)
featureService.CreateFeatureSource(...., ....)

I am using JavaScript :
var featureService = siteConnection.CreateService(MgServiceType.FeatureService);

featureService.CreateFeatureSource(resourceIdentifier, sdfParams);

What do you mean?

There is no MgServiceType declared in JavaScript?
You wrote that you used VB.Net in the original post.

You cannot use any of the Mg* classes from JavaScript because they are server side components.

Ok, then you still have to do:

Dim featureService as MgFeatureService = siteConnection.CreateService(MgServiceType.FeatureService)
featureService.CreateFeatureSource(resourceIdentifier, sdfParams)

In VB.Net, because you cannot call the Mg* classes from JavaScript.

Ok, I changed it to:
var featureService = new MgFeatureService();
siteConnection.CreateService(MgServiceType.FeatureService);

featureService.CreateFeatureSource(resourceIdentifier, sdfParams)

But now I get:
OSGeo.MapGuide.MgUnclassifiedException: An unclassified exception occurred.

When you say ASP.Net with JavaScript, where are you trying to create the feature source, on the client or the server?

MapGuide API has the web server API which can be invoked only from the server side which would handle such things as creating a new feature source and such.

There is also a viewer API written in JavaScript for manipulating the viewer.

The two API's are separate and cover different types of functionality. Creating new feature sources must be done on the server side. This could be done in theory with whatever .Net compliant language you are using. I use C#. I am not sure if you are using VB.Net or even JScript .Net on the server side.

[Carl Jokl]

I will assume this must be JScript .Net because what you are doing could not work at all otherwise but I see the problem in the code:

var featureService = new MgFeatureService(); //You explicity create a new feature service. This is wrong
//This method call retrieves the feature service from the site connection but you are not storing the //returned value
siteConnection.CreateService(MgServiceType.FeatureService);
//This will not work because you explicity created this feature service instead of getting it from the feature ///service
featureService.CreateFeatureSource(resourceIdentifier, sdfParams)

I am not completely familiar with JScript .Net but I would think that this should be

//Get the feature service from the site connection, don't create it explicity.
var featureService = siteConnection.CreateService(MgServiceType.FeatureService);
//Assuming you correctly created the resource identifier and the sdf params elsewhere this should work
if (featureService) //Checking the returned feature service was not null just in case.
{
     featureService.CreateFeatureSource(resourceIdentifier, sdfParams);
}

[Marius_360]

This is exactly how I had it from the beginning, but it gives me “Objects of type 'OSGeo.MapGuide.MgService' do not have such a
member” error

[Kenneth Skovhede, GEOGRAF A/S]

So you are using JScript .Net?

In that case you might have to typecast it:

var featureService = (MgFeatureService)siteConnection.CreateService(MgServiceType.FeatureService);

Not completely familiar with JScript.Net, but the error seems to indicate that the object (featureService) is of type MgService.
MgService is a base class, and also the signature return type for CreateService.
The actual type of the object returned is MgFeatureService.

From what I can quickly read about JScript .Net it seems a bit more JavaScript 2.0 like and so the following may be possible:

var featureService: MgFeatureService = MgFeatureService(siteConnection.CreateService(MgServiceType.FeatureService));

featureService.CreateFeatureSource(resourceIdentifier, sdfParams);

JScript .Net from what I can see has the JavaScript 2.0 style typed variables i.e.

var <variable name> : <variable type>

And if I am reading the information on casting in JScript .Net correctly it looks like casting is a little wierd but of the form: <Variable or Specific type> = <Specific type class>( <variable of general type> );

and not what I would have been used to of <variable of specific type> = (<specific type class>) <variable of general type> which is the C# / Java style way of casting.

[Kenneth Skovhede, GEOGRAF A/S]

There is a class map together with the documentation:
http://mapguide.osgeo.org/2.0/documentation.html

This can be found in the Web API documentation:
http://mapguide.osgeo.org/files/mapguide/docs/webapi/index.htm

The specific class is here:
http://mapguide.osgeo.org/files/mapguide/docs/webapi/d5/d10/class_mg_feature_service.htm

And the "CreateService" is here:
http://mapguide.osgeo.org/files/mapguide/docs/webapi/df/d57/class_mg_site_connection.htm


As for dll, that depends... the class you are seeing is in MapGuideDotNetApi.dll, but it is actually a wrapper
for the other dll files in that folder.

You are a bit unprecise:
"I’ve got the layerdefinitionfactory.php file included in my aspx page"
AFAIK, that is not possible.

The file LayerDefinition.php is a helper file that is used to create the various components of
a LayerDefinition.xml file, defined by LayerDefinition-1.2.0.xsd, for use in a preview of a featuresource.
