[VOLZ Mark (FN)]

Lee,

I'm using this in Autocad map which means a lot of the class names are
different but they are basically they are the same you just need to
replace the AcMap<class> with Mg<class>

                        AcMapResourceService rs;
                        rs =
AcMapServiceFactory.GetService(MgServiceType.ResourceService) as
AcMapResourceService;
                        AcMapFeatureService fs;
                        fs =
AcMapServiceFactory.GetService(MgServiceType.FeatureService) as
AcMapFeatureService;
                        FeatureSourceType fstype = new
FeatureSourceType();
                        //show loading form
                        Loading loadform = new Loading();
                        loadform.StartPosition =
FormStartPosition.CenterScreen;
                        loadform.Text = "connecting to " + fdo;
 
Autodesk.AutoCAD.ApplicationServices.Application.ShowModelessDialog(load
form);
                        //create the connection
                        string xmlstring = null;
                        MgResourceIdentifier fsId = new
MgResourceIdentifier(librarypath);
                        //set fdo details
                        fstype.Provider = fdo;
                        NameValuePairType param1 = new
NameValuePairType();
                        param1.Name = "Password";
                        param1.Value = fdo_password;
                        NameValuePairType param2 = new
NameValuePairType();
                        param2.Name = "Service";
                        param2.Value = datasource;
                        NameValuePairType param3 = new
NameValuePairType();
                        param3.Name = "Username";
                        param3.Value = fdo_user;
                        NameValuePairType param4 = new
NameValuePairType();
                        param4.Name = "DataStore";
                        param4.Value = para1;
                        NameValuePairType param5 = new
NameValuePairType();
                        param5.Name = "LongTransaction";
                        param5.Value = para2;
                        fstype.Parameter = new NameValuePairType[] {
param1, param2, param3, param4, param5 };
                        //serialize the featuresource object model to
xml string
                        using (StringWriter writer = new StringWriter())
                        {
                            XmlSerializer xs = new
XmlSerializer(fstype.GetType());
                            xs.Serialize(writer, fstype);
                            xmlstring = writer.ToString();
                        }
                        //convert unicode string to utf8 bytes for
resource service
                        byte[] unicodeBytes =
Encoding.Unicode.GetBytes(xmlstring);
                        byte[] utf8Bytes =
Encoding.Convert(Encoding.Unicode, Encoding.UTF8, unicodeBytes);
                        //create byte reader of xml feature source def.
& store in repository
                        MgByteSource XmlSource = new
MgByteSource(utf8Bytes, utf8Bytes.Length);
                        try
                        {
                            rs.SetResource(fsId, XmlSource.GetReader(),
null);
                            fs.DescribeSchema(fsId, para1);
                            loadform.Dispose();
                        }
                        catch (MgException ex)
                        {
                            MessageBox.Show("error creating " + fdo + "
connection. \nError reads:\n" + ex);
                        }

The real trick with the autodesk Fdo is the LongTransaction parameter if
you are not using oracle workspaces (oracle versioning) simply set this
to Live if you are using workspaces let me know and I can run through
how to find a version. 

Hope this helps.

Mark

Thanks Mark, I am using Autodesk FDO. I would really appreciate some
example c# .net code would help me a lot.
