Description:

A User Defined Object is an Object that is made by declaring a user program as an Object.

The following table lists the size and availability of the oUserClass Object.

	Object	Size	Description	A1	A2	B1	B2	C1
	oUserClass		An Object created from an ooPIC program.	x	x	x	x	x

Operation:

When a user program is declared in a oUserClass Object's argument list, the user program compiles into the calling program as if it was an Object.

All of the user program's Objects are created and the user program's Main procedure is called at the time that the oUserClass is created. All other procedures become methods of the Object.

All of the user program's Object's properties are accessible by stating the User Class name followed by a period and then the user program's Object and property in normal format.

NOTE: When specifying the filename of the user class, the file path is assumed to be the same as the calling program. If the actual path is different, then the full path will need to be given.

Example:

The following examples use the oUserClass Object.

User-Class

Program that uses the User-Class

'This program operates 
'two oDCMotor Objects.
'saved as "Sample-U.osc"

Dim Right As New oDCMotor
Dim Left As New oDCMotor

Sub Main()
  Right.IOLineP = 17
  Right.Operate = 1
  Left.IOLineP = 18
  Left.Operate = 1
End Sub

Sub Forward()
  Right.Speed = 50
  Left.Speed = 50
End Sub

Sub Backward()
  Right.Speed = -50
  Left.Speed = -50
End Sub

Sub Stop()
  Right.Speed = 0
  Left.Speed = 0
End Sub

'This program uses a user 
'program as an Object
'named "Robot".

Dim Robot As New oUserClass("Sample-U.osc")


Sub Main()
  Robot.Right.Speed = 50
  Robot.Left.Speed = -50
  ooPIC.Delay = 200
  Robot.Forward
  ooPIC.Delay = 200
  Robot.Backward
  ooPIC.Delay = 200
  Robot.Stop
End Sub
