Hello, i have been a member for quite a while but i havent written that much in here, so i guess a little introduction would be in place.
my name is Dan-Levi, i am 30 years old. I started out with server side web development about 12 years ago just until 4 years ago when i started learning c# and all that .NET shizzle, and now i am interested in learning about c++.
So im working in a simple dll injection which loads the CLR and (eventually) a managed dll. i am able to inject the unmanaged dll into the process (notepad in this case) , but i struggle getting CLR to start.
This is what i got so far:
So all HRESULT hr returns S_OK until i actually try to start CLR
Since im coming over from c# and have little to no experience writing c++, i understand the syntax and can make a understanding of the code, but i dont know exactly how to do errorhandling in the right manner in every situation.
I was hoping that some of you could have a look and give me some pointers so i can learn from this and eventually give back to the community with full source once it all is in place.
I want to know how i can debug my code once it is injected into the other process. I have tried to use try catch blocks but no exceptions is thrown from clr and the even inside the try block it crashes.
I want to add that after i inject this dll the clr.dll is in the list of loaded dll's (Process Explorer) but it seems that it fails to start.
I am running this on a Windows 10 X64 setup.
Cheers and thanks for the great community with alot of cool content.
