Debugging Dll

You can debug your code by loading the DLL directly into your application rather than using it in registered mode: see the
CoLoadLibraryfunction[^].hi ,thanks ... one more thing i want to ask how to register the dll . am getting the error message that DLL has loaded but entry point DllRegisterserver was not found ... but am wtritten the code for it
AFX_MANAGE_STATE(AfxGetStaticModuleState( ));
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 return hr;its in a function name STDAPI DllRegisterServer(void) the control not coming in this function what might be cause please reply Best Regards Sarfaraz

I don't see any declaration of
DllRegisterServer()[^] in the above.STDAPI DllRegisterServer(void) this i used in this only i written the code

Used where? Please show the actual declaration. Also make sure that you are exporting this correctly in your build.
hi thanks again now its getting register. i was not exporting correctly .. The dll i wrote for the context menu this is done in 32 bit machine but in 64 bit machine the context menu is not coming ... what might be the problem

what might be the problemAny 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.
