Disabling dyalogrt.exe from popping up message boxes

[harsman]

When an untrapped error occurs, dyalogrt.exe normally pops up a messagebox saying something like "This Dyalog APL application has attempted to use the session and will be terminated".

I have a number of automated tasks running using dyalogrt.exe and it would be nice if they just silently created a CONTINUE.DWS on error instead of trying to pop up a messagebox that no one will see. In fact, if run as scheduled tasks under e.g. the SYSTEM account, the message box is invisible, so the process just appears to hang. I can create a general trap myself that does []SAVE and []OFF, but implementing that in every workspace seems a bit much.

Using RunAsService=1 doesn't disable this behaviour, is there something else I can do to make dyalogrt.exe be quiet and not try to throw up message boxes in case of an error?

Hi,

What is the BuildID of the dyalogrt.exe that you are running?

dyalogrt.exe should not pop up the runtime violation message box if you have set RunAsService=1.

Setting RunAsService will also turn on the DYALOG_NOPOPUPS parameter.

DYALOG_NOPOPUPS
If set to 1, suppress various popups such as the syserror dialog box or runtime violation box.

Regards,

Vince

The build id is 1547663c, v12.1 Classic. I don't actually see any message boxes (there is no user session that can show them since the process is running as a scheduled service) the process just hangs.

However, If I run manually I can see that the cause of the hang is a trap and fixing the trap stops the hang from occuring again.

I'll see if it always happens or only under particular circumstances.
