icon tray question powerbuilder...

i download an example that puts an icon to the tray of windows bar. I checked it and it works.

I insert the menu (called m_icontray) and the connection (called n_icontray) (dont know exacly what it is or how to create this connection). So i import them to one project i created and i tried to call this code:

// add window icon to tray
in_tray.of_add_icon(this)

// register hotkey
If Not in_tray.of_RegisterHotKey(this, 1, in_tray.MOD_WIN, in_tray.KeyF8) Then
      MessageBox(this.title, "RegisterHotKey failed, hotkey already in use!")
End If

this code exists at the open event of the form. But when i save it i have an error saying that the in_tray variable is undefined. I search to find this variable on the prototype project but couldn't found it. Where this variable might be? help please...the project is from the examples page of sybase(you have to login) and is called "icontray.zip"

in the example that you have check the instance variables yoiu must have somnething like
n_icontray in_tray
Integer ii_index
Boolean ib_timer
in the window w_main

Also the function that are defined in the window ( w_main) needsto be copied to your window.

you will need to declare it as an INstance variable
n_icontray in_tray

n_icontray is a user object and contains the major external functions and declrns

// toggle timer event on/off
If ib_timer Then
      Timer(0)
Else
      Timer(1)
End If

----------------------------------

// change icon in the tray
If in_tray.of_modify_icon(this, "shell32.dll", ii_index) Then
      ii_index = ii_index + 1
Else
      // first call failed so go back to icon #0
      in_tray.of_modify_icon(this, "shell32.dll", 0)
      ii_index = 1
End If


What about these two?

ib_timer undefined variable
ii_index undefined variable

where should i put these and what might be integer,long?
