Freddy,

You actually don't need to get the handle specifically. Just put the

following code

in the CHOOSE trigger for your button:

RUN fetchNext in DYNAMIC-FUNCTION('getDataSource').

The getDataSource function will "feed" the SDO's handle into the RUN statement.

Hi Freddy ,

If you want ot get the handle of the DataSource connected to a viewer, you

can use

hHandle = DYNAMIC-FUNCTION('linkHandles':U, INPUT "Data-Source").

This will give you the handle to the SDO and then use

IF VALID-HANDLE(hHandle) THEN

RUN fetchNext in hHandle.

If you want to get a Next record of then use ...

IF VALID-HANDLE(DYNAMIC-FUNCTION('getDataSource')) THEN

RUN fetchNext in DYNAMIC-FUNCTION('getDataSource').

I am writing a program that has a button in the viewer that I would like to

get the next record in the SDO when pressed. How do I get the handle of the

SDO so that I can request the next record from the SDO when the button is

pressed?
