You can use IllegalArgumentException to get "Err:502" (Invalid
Argument) instead, but you can't provide your own error message.
Thanks. That is after all slightly better than the current situation. A
pity though that I cannot provide additional error info in the status bar...
If you return the error message as a string, it depends on your usage
of the function if it is handled correctly.
Yes. It is probably more sensible to just use IllegalArgumentException.
However, I wonder if I could then let the add-in provide a menu item
that says "Check formula in current cell"... If there is a
straightforward way that I can ask OOo Calc to evaluate a given cell
formula I should then be able to wrap the evaluation in a try...catch
block, catch the exception and then display that error message to the
user. I'll try to pursue this idea, unless someone can persuade me that
it is impossible.
Kind regards
