I'm sure this is some simple thing but here goes: I'm trying to use the Java method keyPress(int) which is part of the Robot class. I keep getting the error:

> [@](#):
>
> TypeError: delay(): expected 2 args; got 1

In fact, I get this for every Java function I've tried. Here' s what I've got:

[code]def sendKeyScript(dataSet):  
# Sends the key strokes to the Reflections session....  
import system  
import system.dataset  
import system.db  
import system.util  
import system.gui

```
from java.lang import System
from java.awt import Robot
from java.awt.event import KeyEvent

system.util.execute(["C:\Program Files\Reflection\R8win.exe", "c:\createlabel.rsf"])
Robot.delay(3000)
Robot.keyPress(KeyEvent.VK_C, ret)
Robot.delay(500)

```

[/code]

Try instantiating the Robot object first:

`rob = Robot()
rob.delay(3000)`

That did it, thanks. Kind of a misleading error though.

I think there is a static delay() method that has a different method signature than the void static() method, because if you try this it works:

`rob = Robot()
Robot.delay(rob,1000)`

Which is why the error complained about arguments.
