5. To use the MintMT ActiveX

control in the project, place it

on the form.

The properties of the ActiveX

component include a field

called Name this is the name

used in the code to identify

the ActiveX control, in this

example it is ‘MintController’

6. 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, this will open an editor

window with the cursor in the function called when the form loads. Add the code:

procedure TForm1.FormCreate(Sender: TObject);

begin

// Create handle to controller

MintController.setNextMovePCI1Link (0, 0);

end;

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

Add a button to the form and double click on the button. Borland Delphi will open an editor window

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

procedure TForm1.Button1Click(Sender: TObject);

var

bState: WordBool;

begin

// Read the state of the relay

bState := MintController.Relay [0];

// Invert the state of the relay

MintController.Relay [0] := not(bState);

end;
