Contains the sources for lookup tables.
The ActionLookupSource object contains information about how to read and what contents are stored in an action lookup repository. This repository can be:
The repository contains columns of lookup values that will be used to build an SQL in statement within each of the core actions upon user request. This allows users to manage complex in statements using a common repository rather than individual conditional statements per action.
Example text repository.
| Sample repository file |
|---|
| EVENT_ID, CENTER OIL, G OIL579, F OIL714, J OIL1172, K |
Where the first row defines the column names and the subsequent rows define the data values to substitute in the SQL expression. This would equate to a SQL where statement like CENTER IN('G', 'F', 'J', 'K') if you use the CENTER column or EVENT_ID IN('OIL', 'OIL579', 'OIL714', 'OIL1172') if you use the EVENT_ID column for your lookup values.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
| Interfaces | Description |
|---|---|
| IActionLookupSources | Provides access to properties and methods needed to create the lookup table values from the file or geodatabase sources. |
| IPersistStream (esriSystem) | |
| ISupportErrorInfo | Indicates whether a specific interface can return Automation error objects. |
