Run Time Error

[User (Legacy)]

I just got my trial of ChartFX and am looking to use it in VC++ without MFC.

I dutifully followed the directions about doing this on the knowledge base

and in help.  However when i run the program i get a run time error.

I basically just set up a window and then do this:

  m_pChartFX.CreateInstance(__uuidof(ChartFX));

  m_pChartFX->CreateWnd((long)hChart ,IDC_CHART1,0,0,500,500,WS_CHILD |

WS_VISIBLE);

  m_hwndChartFX = (HWND) m_pChartFX->hWnd;

just as the help says.  I do the CoInitialize stuff as well.  The Error

occurs on the CreateWnd line.  The only place i could be going wrong i guess

is the IDC_CHART1.  What is this?  I first tried it just as a random number

and then made a custom control in a dialog box called IDC_CHART1.  Both

produced the runtime error.  Suggestions on how to fix this are appreciated
