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.

Well, it's your code so presumably wherever you declared those methods. If they are part of some library that you are using then ensure that the library is included in your linker options.

I was a graduate student in Tsinghua University in China.
I'm programming about NC Code Simulation System.
In this program, I used OpenCSG Library to perform a Solid Modeling.
By the way, the sample program supported by library which is programmed in Win32 App, is well operate, but the program that I produced in MFC doesn't well operate. The error is that OpenCSG doesn't draw solid.
How to use OpenCSG Library in MFC?

Please help me.

Best Reguards.

谢谢！
