How do you substitute multiple lines of cpp code?

Question

I have a try-catch with multiple catch-statements. The catch-statments are about 30 lines of code. Many functions have the same catch-statements. I would like to replace them with a single line of code (which would be defined somewhere, like a macro). Is this possbile with c++ / Microsoft Visual Studio?

try {...}
<INSERT SINGLE LINE OF CODE HERE>

Instead of:

try {...}
catch (HRESULT hr) {...}
catch (std::exception & e) {...}
catch (LPCWSTR e) {...}
catch (...) {...}

Thank you.

Thank you for the link. Interesting, but not quite what I was looking for. I simply want to replace. — Silentium Vetzo, Apr 23 '20 at 18:00

What is wrong about a function?

void common_handler() { /* handle common */ }

try {...}
catch (HRESULT hr)
{
    common_handler();
    // handle specific
}
catch (std::exception & e)
{
    common_handler();
    // handle specific
}
catch (LPCWSTR e)
{
    common_handler();
    // handle specific
}
catch (...)
{
    common_handler();
    // handle specific
}

I think he wants to get rid of al the catch statements too and not only the bodies. – wychmaster Apr 22 '20 at 08:26
Yes, I just want to get rid of all the catch statements. For the simple reason of making the code more readable. – Silentium Vetzo Apr 23 '20 at 18:02
