Hi All



I have been messing with my form create and read events and a commuter procedure (ie most of the code is run by calling the commuter proc).  



In my sleep I must have changed the 



Return 0



(return zero)

at the bottom of the CREATE event script (no I can't do without the create event script because it's the only way I've figured out how to get at the createparams)



to 



Return



ie return nothing 



so I got the error when the process tried to pickup and run the system event stuff (after the event script and before the quick event)



ENG0010: RUN_EVENT, line 1. variable has not been assigned a value



Sure had me going for a while. Each time I got the error I had to reboot the computer to get response back. Putting the create event script back to Return 0 fixed the problem. 



When searching using the site search and the search this list the closest I got was a thread about Norwegian Wood.  



Using ENG0010 

and RUN_EVENT 

(run_event and run event seemed to return nothing at all)

and even 

variable has not been assigned a value

seemed to offend the search process into a complete hang.



keywords:

run event RUN EVENT run_event 

create event

var unassigned

missing parameter

(maybe I'll find this again when I need it)



Extract of code:



* B0340 Create Event



Declare FUNCTION UNASSIGNED, SEND_EVENT, CENTER_WINDOW



* Check for key to be loaded from workflow (parent app).

If UNASSIGNED( CreateParam) Then CreateParam=' 

category.item	= FIELD( CreateParam, '|', 2)

act.desc		= FIELD( CreateParam, '|', 4)

class			= FIELD( CreateParam, '|', 5)

new_row			= FIELD( CreateParam, '|', 8)

	

* (edit - set some default values)

If lease_no Then

* lease_no is the key, go get the data

* ie force the read event here

* note - the read event calls the commuter procedure to 

* load up some more form controls with extracts of what it read...

   void=SEND_EVENT( @WINDOW, 'READ')

End 



* centre the window

void=CENTER_WINDOW(@WINDOW,'PARENT')

@@WINDOW-]FOCUS=1



* set the first focus on the control .NEW_CHARGE

void=SET_PROPERTY( @WINDOW : ".NEW_CHARGE", "FOCUS", 1)



* need return 0 here to stop system default stuff running

* and stop that pesky error

RETURN 0

<QUOTE>Scott,

Are you sure?



Have you got a commuter function


<code>

<code>
function XXXXXX( Event, CtrlEntID, Param1, Param2, Param3, Param4, Param5, Param6, Param7 )
begin case
case Event=CREATE"
...etc...
</code>

</code>


?



Then in the CREATE quickevent use the parameters


<code>

<code>
'CREATE','@SELF','@PARAM1'
</code>

</code>




Then the Param1 parameter of your commuter will contain the CreateParams.
