Hinweise
Because of the flexible nature of command objects, only the following checks are performed:
The Name property of the command object is not empty.
The Command object belongs to a Commands collection.
The Statement property of the command object is not empty.
Executing a command is the only way to determine whether the command functions correctly.
Beispiel
Use the following code to return the validity status of a command object:
'Assume a command object (dsoCmd) exists.
If dsoCmd.IsValid Then
'Insert code to save the command.
Else
'Return an error with one or more properties.
End If
