D Dll injection problem

[maarten van damme]

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);
}
