Adding a new field to table in ArcCatalog

Question

I have a command button in ArcMap, this command button working to add a new field to a specific table in ArcCatalog.

e.g. i have a table contains many fields like ObjectID , FeatureName, ... i want to add a new field programmatically while ArcMap is running .

Is there anyway to add a new field to ArcCatalog while the ArcMap is running.

Answer 1

I'm not sure what you mean by "add a new field to ArcCatalog" but from ArcMap you could just locate (best to use Search window in ArcGIS 10 or ArcToolbox previously) the Add Field tool and run it to add a new field.

This the solution :

ITable woTable ;
            ISchemaLock schemaLock = (ISchemaLock)woTable;
            IField newField = this.WOAttributeProperties.getOrSetField;
            try
            {
                schemaLock.ChangeSchemaLock(esriSchemaLock.esriExclusiveSchemaLock);
                woTable.AddField(newField);
            }
            catch (Exception exc)
            {
                System.Diagnostics.Debug.WriteLine("An Error Occured: " + exc.Message);
            }
            finally
            {
                // Set the lock to shared, whether or not an error occurred.
                schemaLock.ChangeSchemaLock(esriSchemaLock.esriSharedSchemaLock);
            }
