Easyhook and whitemagic problems & FSM design question

[!@^^@!]

Hi, i recently managed to inject my code into wow with easyhook and hook up the endscene call with Apoc's whitemagic (thanks for that one btw) however i have problem with wow crashing when closing it, by simply commenting out the code i have in the injected lib i tracked down the error to be comming from the endscene hook or rather the endscene delgate/endscene handler...
is there a function like ApplicationExit i should hook and do my disposing in or is the problem something else i've overlooked?

Another thing, I freaking LOVE the new additions in .net 4 and would like to use it for my project BUT easyhook complains when i try to inject a .net 4 assembly but have no problem doing it with .net 3.5 and below assemblies, therefor i've for the last 2 hours been looking through the source code of easyhook...
I've tracked down the exception to be comming from:

 public static void GacInstallAssembly(
            IntPtr InContext,
            String InAssemblyPath,
            String InDescription,
            String InUniqueID)
        {
            Boolean Res;
            if (Is64Bit) Res = NativeAPI_x64.GacInstallAssembly(InContext, InAssemblyPath, InDescription, InUniqueID);
            else Res =  NativeAPI_x86.GacInstallAssembly(InContext, InAssemblyPath, InDescription, InUniqueID);
            if(!Res)
                throw new ApplicationException("Unable to install assembly in the GAC. This usually indicates either an invalid assembly path or you are not admin.");
        }

so it's calling a importet function from the c++ easyhook dll:

extern "C" __declspec(dllexport) BOOL __stdcall GacInstallAssembly(
        LPINTERNAL_CONTEXT InContext,
        WCHAR* InAssemblyPath,
        WCHAR* InDescription,
        WCHAR* InUniqueID){

    FUSION_INSTALL_REFERENCE InstallInfo;

    // setup installation parameters
    memset(&InstallInfo, 0, sizeof(InstallInfo));

    InstallInfo.cbSize = sizeof(InstallInfo);
    InstallInfo.dwFlags = 0;
    InstallInfo.guidScheme = FUSION_REFCOUNT_OPAQUE_STRING_GUID;
    InstallInfo.szIdentifier = InUniqueID;
    InstallInfo.szNonCannonicalData = InDescription;

    // install assembly with given parameters
    if(!SUCCEEDED(InContext->Cache->InstallAssembly(0, InAssemblyPath, &InstallInfo)))
        return FALSE;

    return TRUE;
}

So it's not because easyhook does some checks on the .net version of the assembly wich i first assumed therefor im pretty clueless about why it doesn't work, any ideas?

Last question:
I've picked up Apoc's http://www.mmowned.com/forums/c/2327...your-bots.html and implemented a few of my own ideas, but regarding the design usage of it, would it be best to "nest" FSM's? like say we have 4 states in the first FSM: BgMode, GrindMode, QuestMode, ProfessionMode
and inside each these states we have a different FSM with states regarding the state of the previous state...

Thanks in advance :wave:

For the .NET 4 issues: .NET 2->3.5 all run on the CLR 2.0, but .NET 4.0 also introduces a new version of the CLR, along with various changes to the CLR Hosting API (CorBindToRuntime and associates are deprecated). I was looking into this a bit for my .NET hosting, but the documentation of the new interfaces (given they are in beta) was incomplete and seemed to be leading down a path of a lot of digging around for minimal short term gain so I left it. Read this article for more info: Hosting Changes in the .NET Framework 4

hmm well then it absolutly makes much more sense...
But short term gain? being able to use a ObserveableCollection<LogEntry> for my log so i can databind my ipc interface directly seems like a pretty big gain imo so i'll have a look at it and see if i can figure it out myself else i'll request it as a feature for easyhook...
and thanks btw

ObservableCollection exists in .NET 3.5.

What I meant by no short term gain was that the code I was injecting didn't use any .NET 4 specific features, so nothing was lost by compiling it to 3.5, and a headache was avoided. I still want to figure out how to do this as there are a lot of cool features in .NET 4 that would be great in injected (and other) apps.

I'm intending to look into and find out more about the parallel feature, among other things.

it does? 0.o i guess it have another namespace then because i just looked in system.collection.objectmodel oh well thanks and have a +rep back
although it's no wonder i didn't notice because when i started learning c# a year ago i used 2.0 and winforms, later i discovered wpf and only used 3.5 for a month because the VS2010 came out with .net 4 and idk why but i like experimenting with beta's....

-edit-

aha i just needed a reference to WindowsBase

For WoW crashing: maybe you did forget to remove your hooks while closing your app?

[!@^^@!]

well idk what was wrong because it's not doing it anymore and i didn't change any code in that section :s

There's an example on how to use new CLR 4.0 hosting interface:
CLR version for .Net Framework 4 beta 2

Ooh cheers thanks for link

If anyone have the same problem as me with wpf databinding whining about modification to a databound list from another thread here is a solution that don't block wow's main thread: Quantum Bit Designs Blog Archive WPF Cross-Thread Collection Binding – Part 4 – The Grand Solution
Thanks for the link TOM_RUS, and oh hey btw i'd still like to know a little more about how you guys have implemented your FSM
