RegSvr32 exit codes [modified]

[sashoalm]

I've got a shell extension dll that can't be registered - regsvr32 fails with exit code 0x3 (this happens on a 64-bit Vista), but I can't understand what the exit code means. Does anyone know what might be the problem and what this exit code means? And this problem doesn't happen in XP 32-bit (my development machine).

Do you have a DllRegisterServer() function?

Yes, it is a ATL/COM shell extension, with MFC support enabled. It was done by following this article from codeproject - http://www.codeproject.com/KB/shell/shellextguideindex.aspx[^] I forgot to mention that the problem *doesn't* happen in XP 32-bit (my development machine).

And what does it return?

Perhaps some required runtime DLL is missing. Use Depends[^] (or some other tool that does something similar) to see if this is the case.

DllRegisterServer is just boilerplate code put by AppWizard, and it returns _Module.RegisterServer(TRUE). Btw, I also have a *.rgs file. Could something be wrong there?

/////////////////////////////////////////////////////////////////////////////
// DllRegisterServer - Adds entries to the system registry

STDAPI DllRegisterServer(void)
{
// registers object, typelib and all interfaces in typelib
return _Module.RegisterServer(TRUE);
}

Actually the entire file is boilerplate, I haven't changed a line of code there I think. Here's the code:

// ExplorerExt.cpp : Implementation of DLL Exports.

// Note: Proxy/Stub Information
// To build a separate proxy/stub DLL,
// run nmake -f ExplorerExtps.mk in the project directory.

#include "stdafx.h"
#include "resource.h"
#include
#include "ExplorerExt.h"

#include "ExplorerExt_i.c"
#include "ExplExt.h"

CComModule _Module;

BEGIN_OBJECT_MAP(ObjectMap)
OBJECT_ENTRY(CLSID_ExplExt, CExplExt)
END_OBJECT_MAP()

class CExplorerExtApp : public CWinApp
{
public:

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

//{{AFX\_MSG(CExplorerExtApp)
	// 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(CExplorerExtApp, CWinApp)
//{{AFX_MSG_MAP(CExplorerExtApp)
// 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()

CExplorerExtApp theApp;

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

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

/////////////////////////////////////////////////////////////////////////////
// Used to determine whether the DLL can be unloaded by OLE

STDAPI DllCanUnloadNow(void)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());
return (AfxDllCanUnloadNow()==S_OK && _Module.GetLockCount()==0) ? S_OK : S_FALSE;
}

thanks for the advice, I checked it, and there was one warning, and two files had red icons to the left. Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module. c:\windows\system32\SHLWAPI.DLL c:\windows\system32\IEFRAME.DLL btw at first i had checked it with 32-bit version of depends, and it gave different results even though it managed to launch on the 64-bit Vista. :confused:

Take a look here. http://www.dependencywalker.com/faq.html[^] Specifically Can Dependency Walker help me figure out why my component won't register?

Thanks, I fixed the problem
