Layer to GML Conversion..

Question

Hi all,

I have been trying this lately, but without any luck so far.. I need to export a layer in my SDE database to a GML File.. I am trying to use the 'Quick Export' Tool available under the Data Interoperability Toolbox for this purpose.. When I am doing this manually through Catalog I have not encountered any problem as such.. However, the same doesnt seem to work when doing it through my code..

Here is a very basic code chunk for this.. 
Geoprocessor m_GP = new Geoprocessor();
                        m_GP.AddToolbox("C:/Program Files/ArcGIS/ArcToolbox/Toolboxes/Data Interoperability Tools.tbx");
                        QuickExport m_QE = new QuickExport();
                        m_QE.Input = "Database Connections/genesis.sde/NE.TELCO/NE.EQUIPMENT";
                        m_QE.Output = "GMLSF, D: /GMLEXP/test.gml";
                        m_GP.OverwriteOutput = true;
                        m_GP.Execute(m_QE, null);

I have tried various input parameters etc nothing seems to actually work.. The code runs through the m_GP.Execute line without any error as such & in a flash.. Hence I can notice that there is no processing in this case.. The D: /GMLEXP Folder remains empty ..

Anyhow would really appreciate if some one can come up with any hints over this..

Regards,
Muneer..

Muneer,

Your issues appears to be not checking out the extension in your script.  I have attached a link to AOInitialize for license Extension codes.

Jeff,

I am doing the same as OP but we don't have a licence for Data Interop.  I have read however that GMLSF export (which is all we need) is possible WITHOUT a license (http://support.esri.com/en/knowledgebase/techarticles/detail/32381) but using the IAOInitialize to check out the extension fails (obviously!).  I am doing this within a Utility COM Object on AGS Standard.

Any clues about how to get this working?
