RemoteCommand

Overview

Provides the ability to dynamically invoke a Command from the server's Schema.

By default, the standard DataAbstractService class is configured to prevent execution of arbitrary commands from the client, as this poses a possible security risk, depending on what kind of commands are defined on your schema.

To enable execution of commands form the client, set the AllowExecuteCommand property of your DataAbstractService to true and ensure that all published Commands in your schema are safe for execution. Also, you need to have proper authentication methods in place to prevent anonymous users from making malicious calls.

ExecuteCall

The DynamicRequest that will be used to invoke the Command on the server. By default, it will be mapped to the ExecuteCommand call as defined in the IDataAbstractService implemented by standard Data Abstract 4.0 servers. When using a custom server interface, you can change its sub-properties to control how the data update call is made.

 

property ExecuteCall: RemoteCommandRequest read;

 

RemoteCommandRequest ExecuteCall { get; }

 

ReadOnly Property ExecuteCall() As RemoteCommandRequest

RemoteService

References the RemoteService component that defines the service to call for executing the command.

 

property RemoteService: RemoteService read write;

 

RemoteService RemoteService { get; set; }

 

Property RemoteService() As RemoteService
