Re: D Dll injection problem
Hmm... It's probably confused by multiple threads. You can try to copy the source for dll_process_attach and insert debugging code there.

return true;

Any help ?
Re: D Dll injection problem
Try to make C dll, which loads D dll, and inject the C dll :)
Re: D Dll injection problem
I found a couple of errors in my code but couldn't get it to work.

Any news about the Problem with D ?
I really would like to use D for that.
Re: D Dll injection problem
I tried again with a few other random C dll's stolen around my system and they all work perfectly. it's only the D dll that gives me trouble.

Re: D Dll injection problem
I went ahead and went back to as far as 2.045 and I still couldn't get a
working dll. This would suggest something is wrong with my dll injection
code but I've tested with a few other random dll's and that appears to
work. according to my debugger the problem is an access violation while
executing the main function of the D dll.
the code I use for injecting is
/**
* injectDLL injects a dll in a given process using the CreateRemoteThread
function.
*
* arguments:
* HANDLE proc = A HANDLE to the process
* string dllName = A string containting the name of the dll
**/
void injectDLL(HANDLE proc,string dllName)
{
//first we need to get a pointer to the loadlibrary function
LPVOID LoadLibAddy =
cast(LPVOID)GetProcAddress(GetModuleHandle(kernel32.dll), LoadLibraryA);
//The problem is that we need to pass an argument(string) but that string
is in our memory space
//so we have to allocate space to write our dllName to using
writeprocessmemory
LPVOID RemoteString = VirtualAllocEx(proc,null,dllName.length,MEM_COMMIT |
MEM_RESERVE,PAGE_READWRITE);
//write the dllName
WriteProcessMemory(proc,RemoteString,toStringz(dllName),dllName.length,null);
//create a thread in the remote process loading the dll
CreateRemoteThread(proc, null, 0, cast(LPTHREAD_START_ROUTINE)LoadLibAddy,
cast(LPVOID)RemoteString, 0, null);
}

If this is a regression, please narrow it down to the exact version.

How do you initialize runtime and GC?

Try to run a simple C program like
---
#include windows.h
void main()
{
LoadLibraryA(mydll.dll);
}
---
And check whether it fails and how.
Re: D Dll injection problem
I wrote my own injector and this makes the target exe call loadlibrary. this works on every dll I try to inject apart from dll's written in D (starting with dmd version 2,054 or something like that). I'll try with D calling loadlibrary on D dll's this evening.
D Dll injection problem
Hey there, I want to inject a dll which was created in D into a c
Program.
Informations:
DMD vs. 2.058
IDE: MonoDevelop with Mono-D
System: Windows 7 64bit
Program Informations:
32-bit
written in c
The Injector is working for sure, so thats not the Problem.
the Source of the DLL:
import std.c.windows.windows;
import core.sys.windows.dll;
__gshared HINSTANCE g_hInst;
extern (Windows)
BOOL DllMain(HINSTANCE hInstance, ULONG ulReason, LPVOID
pvReserved)
{
final switch (ulReason)
{
case DLL_PROCESS_ATTACH:
g_hInst = hInstance;
dll_process_attach( hInstance, true );
break;
case DLL_PROCESS_DETACH:
dll_process_detach( hInstance, true );
break;
case DLL_THREAD_ATTACH:
dll_thread_attach( true, true );
break;
case DLL_THREAD_DETACH:
dll_thread_detach( true, true );
break;
}
return true;
}
It builds fine, but If I inject it, the program (where the dll is
injected) says that the dll is not a valid image.

Maybe it's because I have no def file.
But i dont know how to link it with Mono-D.
Re: D Dll injection problem
when I tried the previous dmd compiler (have yet to try the curent one on this problem) I got the same problems while trying to compile a dll and use it. I have no clue as to why this is happening. worked in 2.54 I thought

Re: D Dll injection problem
Maybe it's because I have no def file. Very possible. Just pass it to dmd like the other files. Or try the new -shared flag.

I have tried both now (shared and def file linking), but know it's crashing my App, lol. I inject it but it returns nothing and the App(where the dll is injected) is hanging( not responding). Could you try it maybe? I would like to know whether it's a Problem with D or with me.
