Description
Fetches current parameter values from the dataset bound to a specified provider.
GetParams provides the underlying implementation of the AS_GetParams method (on the IAppServer interface) and the SAS_GetParams method (on the IAppServerSOAP interface).
ProviderName specifies the name of the provider component whose dataset has the parameters to fetch.
OwnerData represents custom information that originates in a client dataset's BeforeGetParams event handler and returns information that is passed to the client dataset's AfterGetParams event handler.
GetParams returns the parameters, encoded as a Variant array, or, if the provider does not support parameter fetching, GetParams returns a Null Variant. Use the UnpackParams procedure to convert parameter values returned by GetParams to a TParams object.
