Hey Guys

I probably put this post up before but oh well, I have a dll that integrates with explorer and when i try and put my own exported funtion in it crashes the program when i try and access it any ideas.

This is the code:-

Code:

// Note: Proxy/Stub Information

#include "stdafx.h"
#include "resource.h"
#include
#include "Software to Sign and Verify Files.h"

#include "Software to Sign and Verify Files_i.c"
#include "SignShellExt.h"


CComModule _Module;

BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_SignShellExt, CSignShellExt)
END_OBJECT_MAP()

class CSoftwaretoSignandVerifyFilesApp : public CWinApp
{
public:

// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(CSoftwaretoSignandVerifyFilesApp)
public:
virtual BOOL InitInstance();
virtual int ExitInstance();
//}}AFX_VIRTUAL

//{{AFX_MSG(CSoftwaretoSignandVerifyFilesApp)
// NOTE - the ClassWizard will add and remove member functions here.
// DO NOT EDIT what you see in these blocks of generated code !
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};

BEGIN_MESSAGE_MAP(CSoftwaretoSignandVerifyFilesApp, CWinApp)
//{{AFX_MSG_MAP(CSoftwaretoSignandVerifyFilesApp)
// NOTE - the ClassWizard will add and remove mapping macros here.
// DO NOT EDIT what you see in these blocks of generated code!
//}}AFX_MSG_MAP
END_MESSAGE_MAP()

CSoftwaretoSignandVerifyFilesApp theApp;

BOOL CSoftwaretoSignandVerifyFilesApp::InitInstance()
{
_Module.Init(ObjectMap, m_hInstance, &LIBID_SOFTWARETOSIGNANDVERIFYFILESLib);
return CWinApp::InitInstance();
}

int CSoftwaretoSignandVerifyFilesApp::ExitInstance()
{
_Module.Term();
return CWinApp::ExitInstance();
}
