5. To use the MintMT ActiveX control to communicate with a controller a handle to the controller must

be created. This can be done when the form loads. Double click on the form, to open an editor

window with the cursor in the Form_Load function. Add the code:

Private Sub Form_Load()

' Create handle to controller

MintController.setNextMovePCI1Link 0, 0

End Sub

The above code will create a handle to a NextMove PCI controller, card number 0 and node number

6. Add a command button to the form and double click on the button. This will open an editor window

with the cursor in the function that is called when the command button is clicked. Add the code:

Private Sub Command1_Click()

Dim bState As Boolean

' Read the state of the relay

bState = MintController.Relay(0)

' Invert the state of the relay

If bState = False Then

bState = True

Else

bState = False

End If

' Write the new relay state

MintController.Relay(0) = bState

End Sub

This code will read the state of the relay and invert it. Run the application, when the button is

pressed the relay will toggle.
