SDK Question Handle to other Vessel (exception)

[huddi]

Hi,

if I validly call oapiGetVesselByIndex everything is all right.
But if there is no Object for the Index entered, the program crashes.

this

try
{
...
}
catch(...){};

does not work. What else can I do?

Thanks,
Huddi

The function probably doesn't crash in its own right. If the index specified doesn't exist, the handle returned is NULL (0). You need to check the value of this handle before you use it as it is likely this that is causing the exception. I don't think that the orbiter core throws exceptions, so a catch is not likely to work.

I think there is oapiGetNumberOfVessels() or something like that (check in API_Reference.pdf), which will return the number of vessels currently in simulation.

Thanks! This is right

The function is called oapiGetVesselCount()
Thanks too!
