Export does not produce an image - MFC

[User (Legacy)]

Hi

I am  trying to use

Export(CHART_BITMAP, filename) to save a file , but the file is zero bytes.

There is no window associated, I just want to set the attributes and export

the graph to a bitmap.

Can u please provide me a sample or the steps to get this working.

Here are the steps I followed

m_pChartFX.CreateInstance(__uuidof(ChartFX));

 m_pChartFX->ClearData(CD_STRINGS);

  //in general to remove different settings per series in the other charts

   m_pChartFX->ClearData(CD_PERSERIESATTRIBUTES);

   //in general to remove tools like dataeditor, legend boxes set in other

charts

   m_pChartFX->ClearData(CD_TOOLS);

   //to remove the stripes set in the scatter chart

    m_pChartFX->ClearData(CD_STRIPES);

 //set Orientation to LANDSCAPE

 m_pChartFX->Printer->Orientation = ORIENTATION_LANDSCAPE; //LANDSCAPE;

 ICfxAxisPtr pAxis;

   pAxis = m_pChartFX->Axis->Item[AXIS_X];

  pAxis->AdjustScale();

  m_pChartFX->MultipleColors = TRUE;

 m_pChartFX->Gallery = (CfxGallery)BAR;

 m_pChartFX->Chart3D = FALSE;

 m_pChartFX->OpenDataEx((CfxCod) (COD_VALUES|COD_REMOVE), 1, 10);

for (int i=0; i < (iRows-1); i++)

 {

    m_pChartFX->ValueEx[0][i] = 10.00;

   m_pChartFX->Legend[i] = "Text";

 }

 m_pChartFX->CloseData(COD_VALUES);

 m_pChartFX->LegendBox = FALSE;

 m_pChartFX->Axis->Item[AXIS_X]->LabelAngle = 90;

 m_pChartFX->Refresh();

m_pChartFX->EXPORT(CHART_BITMAP,filename);

The chart needs to have a size in order to be exported.

If you are using the DLL, a window HAS to be created even if it is

invisible.

If you are using the OCX, then you don't need to create a window but you do

need to assign a size to the control.

In an OCX, the Size is a property that the container provides not the

control itself.

The CreateControl function in MFC will assign this size for you but it will

also Activate it hence creating a window.

To assign a size without creating a window, you can use

IOleObject::SetExtent

See documentation on IOleObject for details.
