Hi,

I have created a class like this(please see the below code)

class _XTP_EXT_CLASS CXTPMyFrameWnd : public CXTPFrameWndBase<CFrameWnd>

{

public:

DECLARE_DYNAMIC(CXTPMyFrameWnd)

//-----------------------------------------------------------------------

// Summary:

// Constructs a CXTPOleIPFrameWnd object

//-----------------------------------------------------------------------

CXTPMyFrameWnd();

};

in xtpframewnd.h and the implementation in the xtpframewnd.cpp. I have compiled the code and it created the ToolkitPro1110vc80D.dll and ToolkitPro1110vc80D.lib.

when I am using those .dll and .lib in another MFC application with changing the class CFrameWnd to CXTPMyFrameWnd in mainfrm.h, it complies very good but at runtime it shows a messsage called

"The procedure entry point mailto:??1CXTPMyFrameWnd@@UAE@XZ - ??1CXTPMyFrameWnd@@UAE@XZ could not be located in the dynamic link library ToolkitPro1110vc80D.dll". Please suggest, what went wrong an give me a solution for that.

Hi,

remove _XTP_EXT_CLASS - its only for internal classes.

Did you implement constructor for CXTPMyFrameWnd and add IMPLEMENT_DYNAMIC macros ?

Hi,

See error message.

Compiler can't find it - may be you added it in cpp, but didn't add this cpp to project.

Show code with IMPLEMENT_DYNAMIC macro.

xtpframewnd.cpp contains..

IMPLEMENT_DYNAMIC(CXTPMyFrameWnd, CFrameWnd)

CXTPMyFrameWnd::CXTPMyFrameWnd()

{

}

I have added those xtpframewnd.h and .cpp in projects already.

The ToolkitPro1110vc80D.dll and .lib files are created and it's in the debug directory.

error:

2>MainFrm.obj : error LNK2019: unresolved external symbol "public: __thiscall CXTPMyFrameWnd::CXTPMyFrameWnd(void)" ( mailto:??0CXTPMyFrameWnd@@QAE@XZ - ??0CXTPMyFrameWnd@@QAE@XZ ) referenced in function "public: __thiscall CMainFrame::CMainFrame(void)" (??0CMainFrame@@QAE@XZ)

Please help.

Oh, You didnt' wrrite that you modify our source - XTPFrameWnd - why ?

Just move CXTPMyFrameWnd to your application code to MainFrame.h or create own file. Compiler can't find it because you modify file that part of toolkit library.

Hi Oleg,

Many Thanks. I have another query. Please see the below statement.

CFrameWnd* pWndFrame;

GetCommandBars()->SetSite(pWndFrame);

GetCommandBars()->EnableDocking(); ---> Getting Assertion over here.

// Add the menu bar

CXTPCommandBar* pMenuBar = GetCommandBars()->SetMenu(_T("Menu Bar"), IDR_EMBEDDEDPAGE_SRVR_IP);

if(pMenuBar == NULL)

{

TRACE0("Failed to create menu bar.\n");

return -1; // fail to create

}

When I am using the Enabledocking, I am getting assertion in the EnableDocking function code here. ASSERT(!m_pDocks);

But, I have to use the EnableDocking statement in my code, otherwise it is not properly docking the menubar. Please help.

Hello,

Think you didn't create commandbars and GetCommandBars() returned NULL.

Hi,

I have already did like this.

// Initialize the command bars

if (!InitCommandBars())

return -1;

// Get a pointer to the command bars object.

CXTPCommandBars* pCommandBars = GetCommandBars();

if(pCommandBars == NULL)

{

TRACE0("Failed to create command bars object.\n");

return -1; // fail to create

}

I am getting the commandbar,the problem is EnableDocking gives some assertion.Why I need is I have to place the commandbar over the container?

Hi,

I don't like what you do - you host commandbars in one frame but want commandbars appear in another -

GetCommandBars()->SetSite(pWndFrame);

EnableDocking is called automatically in InitCommandBars.

this pWndFrame have to contain commandbars.
