Delete Schematic Diagram Using Code.

[sanjeevsinha]

Hi,

I am trying to delete the Schematic Diagram using the below code. The codes runs fine without any error but diagram is not getting deleted from sde geodatabase. (I have used the ISchematicBuilderEdit.OnDeleteDiagram interface.)

I am using (ArcGis Sever V9.3.1)

private string DeleteSchematicDiagram(string diagramName,string folderName,string schematicDatasetName,IWorkSpace pwksSpace)
{
ISchematicWorkspaceFactory pSchWorkspaceFac = pServerContext1.CreateObject("esriSchematic.SchematicWorkspaceFactory") as ISchematicWorkspaceFactory;
            ISchematicWorkspace pSchWorkspace = pSchWorkspaceFac.Open(pwksSpace);
            ISchematicDataset pSchDataSet = pSchWorkspace.get_SchematicDatasetByName(schematicDatasetName);
            if (pSchDataSet != null)
            {
                ISchematicFolderContainer pSchematicFolderContainer = (ISchematicFolderContainer)pSchDataSet;
                ISchematicFolder pSchematicFolder = pSchematicFolderContainer.get_SchematicFolderByName(folderName);
                ISchematicDiagramContainer pSchematicDiagramContainer = pSchematicFolder as ISchematicDiagramContainer;
               IEnumSchematicDiagram pEnumScheDiag = pSchematicDiagramContainer.SchematicDiagrams;
               ISchematicDiagram pSchDiagram = null;
               for (int i = 0; i < pSchematicDiagramContainer.SchematicDiagrams.Count; i++)
               {
                   ISchematicDiagram finalSchemDiagram = pEnumScheDiag.Next();
                   if (finalSchemDiagram != null)
                   {
                       if (finalSchemDiagram.Name == diagramName)
                       {
                           pSchDiagram = finalSchemDiagram;
                           break;
                       }

                   }
               }//For loop

               if (pSchDiagram != null)
               {
                   ISchematicBuilder pSchStandardBuilder = pSchDiagram.SchematicDiagramClass.SchematicBuilder as ISchematicBuilder;
                   ISchematicBuilderEdit pSchematicBuilderEdit = pSchStandardBuilder as ISchematicBuilderEdit;
                   try
                   {
                       pSchematicBuilderEdit.OnDeleteDiagram(pSchDiagram);
                   }
                   catch (Exception exp)
                   {
                       return "ERROR^" + exp.Message;
                   }

               }


            }
            else
            {
                return "ERROR^Schematic dataset not found.";
            }
}

Thanks for any help......

Thanks & regards

So assuming you already have an ISchematicDataset, you need to use the ISchematicProjectMgr object to get the NgProject.  From there you get the NgDiagram etc...  The ISchematicProjectMgr is the key to moving between the essentially 2 worlds in Schematics:

1. ISchematic... - something stored on disk
2. INg... - something in memory or hydrated for actual display

So ISchematicDataset and INgProject are the equivalents, then ISchematicDiagram and INgDiagram etc... etc...


No more dual posting please...
