Exception not caught

[alogrep 0]

Hi.

It is a few days that the IDE does not catch unhandled exceptions. For example, if i put a line with a division by zero, it just goes on. Before the system caught it and the app stopped after the error message. I have checked for any 'forgotten' Application OnException in my code, but I found none.  The settings in Compile and Linking are shown in the attached picture. What else should I check, please?

Shouldn't you be in the Debug configuration settings?

[Brian Evans 118]

The debugger catches them before they are handled in the application/project not after.

 

When shown by the debugger there is a checkbox to ignore that class of exception going forward.

Or maybe floating point exceptions are masked so there is no exception. We can't see your code, or know what version you use.

Are you using C++ or Delphi? Integer division or floating-point division? Can you provide an example that is not working for you?

The version also matters since it was changed for version 12.

Thanks to all.

No, the division by zero was an exampte (and a test I actually didi).

It is all exceptions (that are not handled)

The more critical one is when I set a table to an index name that does not esxist. 

The app just exit, no wrnings.

Doesn't sound like it's not that exceptions aren't handled. App exiting is entirely different. How about the details we asked for.

OOps!.

I got confused .

What happens is this

I have this bit of code

 

begin
n:=0;
d:=100/n;
if d>0 then
n:=1;
dm2.tabstable.indexname:='xyz';

The first error is ignored, no warning, no message.

The second error is  caught, but it does notshow the call stack, so I do not know WHERE it happens (in this case yes I know, but is

a nightmare when it may happen God only know where)

That code is performing floating-point division. And as Lejos mentioned, floating-point exceptions behave differently in Delphi 12 than they did in earlier versions.

This is also documented by Embarcadero:

If you want to see a Call Stack at runtime, you have to display it yourself. You can catch the Exception (or use the TApplication(Events).OnException event) and then read the Exception.StackTrace property. However, this requires you to install a 3rd party exception logging library, such as MadExcept or EurekaLog, to populate the trace details. Embarcadero does not provide that functionality. In which case, you may as well use that library's own logging capabilities.
