dll injection error handling #514

Open Kengyen opened 1 year ago

Kengyen commented 1 year ago

I inject .dll to a window and it produces: thread 'DEVELOP' panicked at 'called Option::unwrap() on a None value', library\std\src....\backtrace\src\dbghelp.rs:338:34

That line number seems to indicate that looking up the SymInitializeW function in dbghelp.dll using GetProcAddress fails for some reason.

when using if let Err(e) = expression it would panic use match pattern it would be ok
