It is not possible to associate an error message to errors returned by COM component. But method “getLastErrorMessage” defined in the FeResPost Application class allows retrieval of the message associated with the last exception raised by FeResPost. This method can be used to retrieve and print the message. Here is a ruby example of exception management with COM component:
begin
db.readBdf("unit_xyz_V1.bdf",["../../MODEL/MESH/"],"bdf",nil,true)
rescue Exception => x then
printf("\n\nMaybe you should modify the two first include statements in main file!\n")
printf("**********************************************************************\n\n")
puts frpApp.getLastErrorMessage()
end
