GetWindowExW and LdrLoadDll not working

[callmeteus]

I'm trying to normally hook GetWindowExW and LdrLoadDll, both of them doesn't work.
My experience with assembly is not the best, so I'm strugling to understand why it's in fact failing.

I know that my signatures are correct, I really think the problem is inside the DDetours library itself.

Here's a sample code for LdrLoadDll:

type
    NTSTATUS = Cardinal;
    PUNICODE_STRING = ^UNICODE_STRING;

    UNICODE_STRING = packed record
        Length: Word;
        MaximumLength: Word;
        Buffer: PWideChar;
    end;

implementation

var
    // LdrLoadDll
    LdrLoadDllHook: function(pDllPath: PWideChar; dwFlags: DWORD; pUniModuleName: PUNICODE_STRING; var pResultInstance: PPointer): NTSTATUS; stdcall = nil;

function OurLdrLoadDll(
    pDllPath: PWideChar;
    dwFlags: DWORD;
    pUniModuleName: PUNICODE_STRING;
    var pResultInstance: PPointer
): NTSTATUS; stdcall;
begin
    Result := NTSTATUS($C0000022);
end;

begin
    BeginHooks;
    @LdrLoadDllHook := InterceptCreate(GetProcAddress(GetModuleHandleW('ntdll.dll'), 'LdrLoadDll'), @OurLdrLoadDll);
    EndHooks;
end.

I'm getting the following exception when LdrLoadDll gets called:

It seems like it's trying to compare some invalid memory (that is pointing to 0x0000001):

Okay, I've actually managed to fix the LdrLoadDll issue, but the CreateWindowExW one is still bothering me :/
Same as #41
