Remarks

The CoreAutomationRemoteOperation virtual machine uses a register-based instruction set architecture.

The virtual machine has 232 registers, each addressed by a 32-bit integer, referred to as operand registers. An AutomationRemoteOperationOperandId is the integer value that refers to an operand register.

Registers can be reassigned as needed.

Unless initialized through a call to ImportElement or ImportTextRange, all registers are unbound (do not refer to any operands) when CoreAutomationRemoteOperation.Execute(System.Byte[]) is called and the remote operation starts.

The virtual machine supports the following types:

  • Primitives
    • Signed 32-bit integer
    • Unsigned 32-bit integer
    • Boolean
    • Double-precision floating point number
    • Two-byte character
    • Point – a pair of X and Y coordinates, each of which is a double-precision float
    • Rect – a four-tuple of Height, Width, X, and Y values (each a double)
  • Reference types
    • Remote UIAutomation Element – a representation of functionality typically exposed by the IUIAutomationElement interface
    • Remote UIAutomation Patterns – a different type exists for every UIA pattern
    • String – a sequence of two-byte characters used for any UIA (strings are immutable)
    • Array – a collection that can contain a heterogeneous sequence of remote objects
    • StringMap – a map of remote strings to remote objects (supports heterogeneous types)

Fields

Value

The 32-bit integer address of the operand register.
