Programming Forums - "debug Assertion Failure"

i had a simple windowed app going. it was working fine until i made a menu resource and tried to add it to the window -- the program ended early with some dialog to do with debug assertion failure or whatnot.

#include <afxwin.h>

#include "resource.h"



class SoundBlade : public CWinApp

{

public:

        virtual BOOL InitInstance();

};



class CMainFrame : public CFrameWnd

{

public:

        CMainFrame();



protected:

        /* message that deals with creation of the window */

        afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);

        DECLARE_MESSAGE_MAP()

};



CMainFrame::CMainFrame()

{



        Create(NULL, "Resources Fundamentals", WS_OVERLAPPEDWINDOW,

   CRect(200, 120, 640, 400), NULL,

   MAKEINTRESOURCE(IDR_MENU1));

}



/* A table of messages will be enumerated between the following two macros. */



BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)

        ON_WM_CREATE()

END_MESSAGE_MAP()



/* deal with specific messages here */



int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)

{

        // Call the base class to create the window

        if( CFrameWnd::OnCreate(lpCreateStruct) == 0) return 0;

        // Otherwise, return -1

        return -1;

}



BOOL SoundBlade::InitInstance()

{

        m_pMainWnd = new CMainFrame; //get a frame/window object

        m_pMainWnd->ShowWindow(SW_NORMAL); //show the window



        return TRUE;

}



SoundBlade theApp;

i changed the code in the constructor, it was originally

Create(NULL, "Resources Fundamentals", WS_OVERLAPPEDWINDOW,

   CRect(200, 120, 640, 400), NULL);

in other words all i have tried to do is add a menu. this one change forces the program to somehow show me a "Debug assertion failed" dialog with Ignore, Retry and Abort buttons. After I press anyone of those, I'm given a debug dialog. When I click that I'm sent into some heavy looking Microsoft code that I don't think I should mess with.

some more info, hopefully it'll offer some insight
