Reseource Problem with multiple charts when Importing.

[User (Legacy)]

Good morning Frank! 

I have a important problem for you.  I have an application that opens up to 

16 charts (which I create dynamically using VC6.0 and the dll).  The problem 

is that the charts cause a massive resource hit (40+% for 25 charts, 30% for 

16 charts, 16% for 8 charts) when I import them.  This causes my User's 

computer to crash if they have almost anything else open.  I tracked down 

the problem to the actually import statement from the chart fx object- Ie. 

if I import the chart from a file, its hits my resources hard, if I dont 

import it- no major resource hit (it tends to reduce the hit to 2-3%).  This 

is even if I edit the chart to look like an imported chart- it doesnt hit 

the resources until I load it from a file. 

Any solutions to this problem would be very appreciated. 

Here is the main code for this problem: 

hfile = CreateFile(m_filename, GENERIC_READ, 0, NULL, OPEN_EXISTING, 

   FILE_ATTRIBUTE_NORMAL, NULL); 

if (hfile != INVALID_HANDLE_VALUE) 

{ 

   GetWindowRect(rc); 

   ScreenToClient(rc); 

   long l = GetWindowLong(m_hWnd, GWL_WNDPROC); 

   int ID = IDC_CHARTPLOT1 + 1; 

   int i = 0; 

   for (i = 0; i < MAX_PLOTS_PER_PAGE; i++) 

   { // for each chart, create a m_pChartFX 

    if (SUCCEEDED(hr = CoGetClassObject(__uuidof(ChartFX), 

CLSCTX_INPROC_SERVER, 

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

     hr = pFactory2->CreateInstanceLic 

            (NULL, NULL, IID_IUnknown, license, (LPVOID FAR *) &pUnk); 

     if (SUCCEEDED(hr)) 

     { 

      m_pChartFX[i] = pUnk; 

      pUnk->Release(); 

     } 

     else 

     { 

      MessageBox("Createinstancelicense failed"); 

     } 

    } 

    m_pChartFX[i].Release(); 

    m_pChartFX[i].CreateInstance(__uuidof(ChartFX)); 

    m_pChartFX[i]->OpenDataEx((CfxCod) (COD_XVALUES), 1, COD_UNKNOWN); 

    m_pChartFX[i]->OpenDataEx((CfxCod) (COD_VALUES), 1,COD_UNKNOWN); 

    m_pChartFX[i]->ValueEx[0][0] = 0; 

    m_pChartFX[i]->XValueEx[0][0] = 0; 

    m_pChartFX[i]->CloseData((CfxCod) (COD_XVALUES  | COD_SMOOTH)); 

    m_pChartFX[i]->CloseData((CfxCod) (COD_VALUES | COD_SMOOTH)); 

    m_pChartFX[i]->FileMask = (CfxFileMask) 

     ( FMASK_COLORS  | FMASK_ELEMENTS | FMASK_EXTENSIONS | FMASK_FONTS 

     | FMASK_GENERAL | FMASK_LABELS   | FMASK_MULTI  | FMASK_PRINTERINFO 

     | FMASK_SCALE   | FMASK_TITLES); 

   for (i = 0; i < MAX_PLOTS_PER_PAGE; i++) 

   { // for each chart, create a m_pChartFX 

      m_pChartFX[i]->CreateWnd((long)this->m_hWnd, (ID + i), 

       rc.left, rc.top, rc.right, rc.left, 

       WS_CHILD | WS_THICKFRAME); 

      m_hwndChartFX[i] = (HWND)m_pChartFX[i]->hWnd; 

      pFactory2->Release(); 

      ::ShowWindow(m_hwndChartFX[i], SW_SHOW); 

   // here is the problem code - each time this next line is called, i lose 

2-3% of resources.... 

      m_pChartFX[i]->Import(CHART_CFXFILE, (long)hfile); 

      Sleep(0); 

   } 

   l = GetWindowLong(m_hWnd, GWL_WNDPROC); 

  CloseHandle(hfile); 

  } 

Thanks in advance...
