Thread and ChartFX Client Server 5.1 with Visual C++ 6.0

Hi everybody,

I would like to know if we can put a chartfx control in a thread because I

do so but I have a problem. The graph is plotting itself and then every

lines dissapears. Is there any issues with thread with ChartFX ? This is

what I've done to put chartFX in thread.

1. Put those lines in the .h file to create the thread

static UINT ThreadFunc(LPVOID pvParam);//thread function

CWinThread *pThread; //the thread

2. Create a structure in the .cpp file

struct ThreadDataTest


CTestSDIDoc *pDoc1; //pointer to the active document

HWND hWnd; //Pass CWnd objects by HWND

test *testPtr; //pointer to the dialog


3, Create the function ThreadFunc

UINT test::ThreadFunc(LPVOID pvParam)


ThreadDataTest *td = static_cast<ThreadDataTest *>(pvParam);


... //code to plot a graph

delete td; //free allocated memory for the structure

return 0;


4. Call the thread

ThreadDataTest *td = new ThreadDataTest;

td->pDoc1 = CTestSDIDoc::GetDoc();


td->testPtr=this;//this is the current object

pThread = AfxBeginThread(ThreadFunc,(LPVOID)td) ;//start the thread

In addition to this, I have created 2 chart with those lines in .h and .cpp

files CWnd m_ChartFX,m_ChartFX2; IChartFXPtr m_pChartFX,m_pChartFX2;

// ***CFX***

// Do not use class wizard to generate these. It will cause the generation

of unecesary classes DDX_Control(pDX, IDC_CHART1, m_ChartFX); if

(!pDX->m_bSaveAndValidate) // Link Chart FX pointer to control window

m_pChartFX = m_ChartFX.GetControlUnknown(); DDX_Control(pDX, IDC_CHART2,

m_ChartFX2); if (!pDX->m_bSaveAndValidate) // Link Chart FX pointer to

control window m_pChartFX2 = m_ChartFX2.GetControlUnknown(); // ***CFX***

Thanks a lot,
