Is the recordref open?

Ril

Am I missing the obvious parameter or function in C/side which would actually allow me to check if a recordref is open?
This to avoid the error from NAV saying RECORDREF variable not initialized.

Hope any one knows or maybe have a workaround other than keeping some parallel index for open or not.

It is needed for a temporary based array where i keep differnt tabels in differnt indexes, though out a process

Index[x,y] may have an open recordref but at runtime i need to check this.

You can try this:
-create a new codeunit with a function that accepts a recordreference and function puts it in a global variable.
-in the OnRun-trigger access the variable so it gives an error if not initialized.

To control if the variable is initialized :
-Make a global (cduTestRecordReference) to that new codeunit.

CLEAR(cduTestRecordReference);
cduTestRecordReference.SendRecordReference(rerTheRecordReference);
IF cduTestRecordReference.RUN THEN
  MESSAGE('recordreference is initialized');

Thank you for your reply - i did already try this approach - how ever in the context im running - i am able to crach the NAS - because NAV - blocks on the execption even though it was catched by the IF cu.run thing.
So this does not do the trick for me.

So conclusion is that I have to maintain a persited index keeping track on sets open - and in the same post hope that NAV development reads this and fixes this obvious lack of functionallity in c/side using RecordRef.

If I understand the question correctly, you want to check if the RecordRef has been initialized to something or not, is that correct?

If so, this is dirty, but:

IF FORMAT(MyRecordRef) <> '' THEN
BEGIN
    ...
    ...
END;

Dirty but very nice!
Can you create a new topic in the tips&tricks forum with this one?

Thank you MTC - that was exactly it - dirty who cares - c/side on the edge is often dirty, knowing all the dirty trick is what makes the c/side "programmers" world go round.

Sure, will do.

comming back to this topic, because i ran into the “The length of the source exceeds the size of the destination buffer” Error with the dirty solution (IF FORMAT(RecordRef) then ... )

and the kriki-solution (if Codeunit.RUN then ... ) has a small but importend disadvantage: it can't be used in write transactions


using NAV5 and NAV6 classic.


are there any other solutions, how to test whether a record-Ref is initialized or not?

Tried this on a NAV 2009R2 classic:

MESSAGE('%1',recref.NUMBER);

and when it is not initialized, it returns 0.

THX, this is working fine.
