Re: Question about creating chart using CreateWnd

[User (Legacy)]

Good afternoon, Frank 

I added the article's code to my app, and it didnt work.  Looking at the 

code: 

  static CLSID const clsid = { 0xFFF90AC1, 0x4659, 0x11d1, { 0x8f, 0xd4, 

0x0, 0xaa, 0x0, 0xbd, 0x9, 0x1c } }; 

  _bstr_t license = "<<my string>>"; 

  IClassFactory2 *pFactory2; 

  LPUNKNOWN pUnk; 

  HRESULT hr; 

  IChartFXPtr pChartFX; 

  if (SUCCEEDED(hr = CoGetClassObject(clsid, CLSCTX_INPROC_SERVER, NULL, 

IID_IClassFactory2, (LPVOID FAR *) &pFactory2))) 

   hr = pFactory2->CreateInstanceLic(NULL, NULL, IID_IUnknown, license, 

(LPVOID FAR *) &pUnk); 

   if (SUCCEEDED(hr)) 

    pChartFX = pUnk; 

    pUnk->Release(); 

   } 

   pFactory2->Release(); 

  } 

  long l = GetWindowLong(m_hWnd, GWL_WNDPROC); 

  m_pChartFX.CreateInstance(__uuidof(ChartFX)); 

  m_pChartFX->CreateWnd((long)this->m_hWnd, IDC_CHART1, 

   rc.left, rc.top - 5, (rc.right- rc.left), (rc.bottom - rc.top), WS_CHILD 

| WS_VISIBLE); 

  m_hwndChartFX = (HWND)m_pChartFX->hWnd; 

  ShowWindow(SW_SHOW); 

  UpdateWindow(); 

The code is throwing an abnormal program termination on the actual CreateWnd 

call.  CreateInstance comes back fine.  Any other suggestions?  Also I 

wanted to ask how long is the license string?  I did not have a license 

string printed on my license card and when I run About Chart  FX 98, it 

seems the license string may be cut off at the end.  My license string I get 

is 52 characters long. 

Thanks for the help!
