ExpressionEvaluator.LoadAll Method (PIA)
Use this method to pre-compile all expressions in the expression store. Each expression that pre-compiles correctly is loaded into the expression cache.

| &H81100022 | Invalid expression argument value, or impossible conversion |
| &H81100016 | Invalid clause encountered |
| &H8110001F | Invalid connection |

Remarks
Any expressions in the expression cache at the time of the call are reloaded.
If there are many expressions in the expression store, the LoadAll method may be slow. Use the LoadExpr method to load only specific expressions into the expression cache.
For every expression loaded into the expression cache, the LoadAll method increments the read-only ExprCount property by one (1).
Use the FlushAll method to remove all expressions from the expression cache.
The Connect method must be called before using the LoadAll method.
