Hi Andrés!

Andres wrote: But now I wanted to get the placement (i.e. x and y) for an object in a graph, and I receive a marshalling error when I do so (MEAny place (MEOop receiver)). I tried asking first for the diagrams, that is ok, I get a list of diagrams. But anyway, using those diagrams as receiver for place() give me the same error as when I use the actual objects (for example, Button or Text) as receiver. Could somebody give me a hint on what is needed to find out the x,y location coordinates?

 

Without seeing your code I would assume that you are trying to pass the conceptual objects as parameters where as the API is expecting the object representations. Try out the following piece of code with the Watch Example in the Demo repository to see if you can get a list of all object places in 2008Models diagram without any troubles:

 

using System;

using System.Net;

using System.IO;

using System.Text;

using System.Collections;

using System.ComponentModel;

using System.Data;

 

public class APIClient

{

  public static int Main()

  {

    /// Set the variable and initialize connection to MetaEdit+ API

    MetaEditAPIPortTypeClient meServer = new MetaEditAPIPortTypeClient();

 

    /// Variable holding "2008Models" graph's oid

    MEOop wModels = new MEOop();

    wModels.areaID = 22;

    wModels.objectID = 962;

     

    /// Fetch the diagrams for "2008Models"

    MEOop[] diagrams = meServer.diagrams(wModels);

    /// Fetch object representations for first diagram

    MEOop[] objReprs = meServer.objectReprs(diagrams[0]);

    /// Print out the place for each object representation

    foreach (MEOop objRepr in objReprs)

    {

      Console.WriteLine("Place: " + meServer.place(objRepr).meValue);

    }

 

    return 0;

 

  }

}

 

If this does not clarify the situation, please send us the problematic part of the code and we will look further.

 

 

With best regards,
