You can debug your code by loading the DLL directly into your application rather than using it in registered mode: see the CoLoadLibrary function[^].

	HRESULT hr = RegisterServer (AfxGetInstanceHandle(),   // handle to dll module
	                             CLSID_CCmpnt,	      // component CLSID
				     g_szFriendlyName,	      // friendly name
				     g_szVerIndProgID,	      // version independent prog id
				     g_szVerDndProgID);		// version dependent prog id

I don't see any declaration of DllRegisterServer()[^] in the above.

Used where? Please show the actual declaration. Also make sure that you are exporting this correctly in your build.

Any one of a million things. As I just said to someone else in these forums, you need to give specific details, don't expect people to be able to guess what is happening in your code.

ok sorry ..
the code i build in 32 bit its success but when i configure the VS 2010 for 64 bit the error message con not instantiate the
HRESULT IContextMenu::GetCommandString(UINT_PTR,UINT,UINT *,LPSTR,UINT)' : is abstract
see declaration of 'IContextMenu::GetCommandString'
why this conflict

In DLL i have written the code for Context menu in vs2010 using COM
i derived the class CRsEraser : public IContextMenu, public IShellExtInit
this IShellExtInit and IContextMenu is are com class
when use it

HRESULT __stdcall CCmpntFactory::CreateInstance (IUnknown *pUnknownOuter, const IID& iid, void** ppv)
{
if(pUnknownOuter != NULL)
return CLASS_E_NOAGGREGATION;

CRsEraser *pCmpnt = new CRsEraser;
if (pCmpnt == NULL)
return E_OUTOFMEMORY;

HRESULT hr = pCmpnt->QueryInterface (iid, ppv);

//////////////////////////////////////////////////////////////////////////
// Release the IUnknown pointer
pCmpnt->Release ();

return hr;
}
CRsEraser *pCmpnt = new CRsEraser;this part showing its abstract class .
in 32 bit compile its working fine same when configure to 64 bit its throwing the error what i have mention earlier .
how i configure:
1 Open your Visual C++ Solution
2 Choose Build->Configuration Manager menu
3 Inside the Configuration Manager window, change the ‘Active solution platform’ to x64. If you don’t have any, you would need to create one by selecting the ‘New..’ drop down item. Copy settings from your Win32 platform.
4 Now rebuild your solution.

You can use the Custom Draw[^] feature of all Windows controls.

Look at the error messages. They are telling you that certain external functions that you reference cannot be found within the project. Find out where these are supposed to be defined and ensure that they are externalised.

You are correct but how to find its definition?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
