[Guide] Creating a Simple Loader with Injected DLL for Silkroad

If you are compiling your own code, you need to make sure to run in Release mode and choose "Multi-threaded (/MT)" under "Configuration Properties -> C/C++ -> Code Generation -> Runtime Library". This cases the static runtime libraries to be used so you do not have to worry about DLLs for redistribution. For debug mode, choose "Multi-threaded Debug (/MTd)" but when you use detours, you need to run in Release mode.

you need to explain better on how to run it bro, i get confused alot like whoaa.. idk how to get to silkroadframework folder, i finished everything, then next thing u know the debug folder isnt in my main folder?? help plz

I think you aren't compiling the Common.cpp file, but I could be wrong.

[* White *]

when i need to injecy dll there is no dll in debug folder..

[vorosmihaly]

you need to compile that yourself... -.-"

[NUKER_PUMA]

very nice !

[marius1000]

im trying it on elite sro and it gives c8 error...i replaced the login server from gwgt to login.sro.vn still same thing...if you could help!

C8 means you didn't use a command line for starting the client (no locale sent).

1st i'd like to thank You for ur effort "Drew Benton"
and i have 2 questions
1-i have been disconnected from silkroad world server after i run the loader.exe and login to the game
what is the reason?
2- i'm not good in C++ and i saw the code is hard for me to understand
i know java and C# is there a way to convert the code to C#

thank you
& plz reply me

[Haxor]

thank you

You could do a few things in C#, but you'd still need to use C++ for the low level stuff. There's ways you can implement it all in C#, but it's not really worth it unless you wanted to spend the time and be limited with what you could do.

There is some cool stuff you can do when you mix them though. For example, using this concept: you can actually take your C++ Loader/DLL and add .Net capabilities to it.

Since C# is .Net and VB.Net uses .Net, this means you can essentially add C# and VB.Net code to any process. The main limitation of passing data between C++ and .Net is that you can only use 1 (unicode) string, but you can also setup other mechanisms.

However, to really get any awesome stuff going on, you need to know C/C++ as well as ASM language wise and general reverse engineering stuff to be able to setup the codecaves and detours to allow your higher level code to make use of the lower level stuff!

I learned c# 1 year on school and now im trying to get better on it espically in sro related things and creating tools etc..
I dont like learn like more language that use another syntax , I see that everything built in c++ , But i like to take deep in c#
So i just saying if you can just make some c# tutorials
I just take a look of silkroadapi and the examples and it was great
it helped me alot

if you do not learn basic ASM and binary stuff, your sro development status
isnt going to get very far.

Thanks for advise
I want some References to the Assembly that help me in the silkroad development
