How to make my application safe from crashing, when at runtime there is possible crash in the DLL it is using.

Example: Say my "Application1" is using third party "dll1". Becuase of some bad programming "dll1" gets a runtime exception in processing call "GetSummary" (just for example) and it crashes. How can I assure my "Application 1" does not crash?

If the DLL is written in C or it is not throwing any exception, how can we handle it?

Solution 3

Actually crash in DLL cannot be solved until u have the source code.

But from your point.

You can place the DLL loading part in try{ ... } catch( ... ){} .

Which will help your application to not get crashed. But i you have to ensure that DLL is not making errors so that DLL functions cannot be used.

Solution 1

Use C++ exception handling to supress the errors.

Your question has conflicting information. You say "dll1" "gets a runtime exception" (I imagine you mean "throws a runtime exception"), but you also say "if the DLL is written in C or is not throwing any exception, how can we handle it". Is it or isn't it throwing an exception? And what language is Application1 written in? If it's not throwing an exception, then it shouldn't be a problem. If it is and you're working with C++, then catch the exception and suppress it.
