Debugge dll i visual c++

Hej,

Jeg kan godt kopilere følgende c++ kode og delphi kode men jeg før følgende fjel når chartest kaldes:

access violation at address .....

Er det muligt at starte delphi programmet fra C++ så man kan debugge dll'en?

Tchartest = function ():Pchar; {$IFDEF WIN32} stdcall; {$ENDIF}

...

procedure TForm1.button1Click(Sender: TObject);
var
chartest:Tchartest;
DLLHandle: THandle;
seq:Pchar;
begin
    //load dll
    DLLHandle := LoadLibrary(Pchar('.\dlls\chartest.dll'));
    if DLLHandle <> 0 then
      begin
      @chartest :=GetProcAddress(DLLHandle, 'chartestF');
      seq:=chartest();
      end;
    end;
FreeLibrary(DLLHandle);
resultmemo.Lines.Add(seq);
end;


// TestScore.cpp : Defines the entry point for the DLL application.
//

#include "stdafx.h"
#include "TestScore.h"



BOOL APIENTRY DllMain( HANDLE hModule,
                      DWORD  ul_reason_for_call,
                      LPVOID lpReserved
                    )
{
    switch (ul_reason_for_call)
    {
        case DLL_PROCESS_ATTACH:
        case DLL_THREAD_ATTACH:
        case DLL_THREAD_DETACH:
        case DLL_PROCESS_DETACH:
            break;
    }
    return TRUE;
}


// This is an example of an exported variable
TESTSCORE_API int nTestScore=0;

// This is an example of an exported function.
TESTSCORE_API char* chartestF(void)
{
    char* pstringchar =  "test";
    return pstringchar;
}

mvh,
