I try to use ListDataProvider on my Chart in Visual C++ 2005.

I add in stdafx.h these 2 lines :

#import <ChartFX.ClientServer.data.dll> rename_namespace("Cfx62Data")

#import <ChartFX.ClientServer.core.dll> rename_namespace("Cfx62") 

rename("min","minX") rename("max","maxX") 

exclude("_CollectionBase","_Component","CollectionBase","Component")

Here is the code that cause problem :

Cfx62Data::_ListDataProviderPtr m_listDataProviderPtr = 

Cfx62Data::_ListDataProviderPtr( __uuidof(Cfx62Data::ListDataProvider) );

int nTest1[3] = { 1,2,3 };

int nTest2[3] = { 4,5,6 };

CString nTest3[3];

nTest3[0] = CString("a");

nTest3[1] = CString("b");

nTest3[2] = CString("c");

HRESULT result1 = m_listDataProviderPtr->AddCollection( (VARIANT*)nTest1 );

HRESULT result2 = m_listDataProviderPtr->AddCollection( (VARIANT*)nTest2 );

HRESULT result3 = m_listDataProviderPtr->AddCollection( (VARIANT*)nTest3 );

m_chartPtr->DataSource = m_listDataProviderPtr->Get_Ptr();

All lines seem to work fine but the result is an empty chart. What is the 

problem?

Thanks

Marc

I found a solution :

 m_chartPtr->ClearData(Cfx62::ClearDataFlag_AllData);

 m_chartPtr->_Gallery = Cfx62::Gallery_Curve;

 Cfx62Data::_ListDataProviderPtr m_listDataProviderPtr = 

Cfx62Data::_ListDataProviderPtr( __uuidof(Cfx62Data::ListDataProvider) );

 double dTest1[3] = { 0,1,2 };

 double dTest2[3] = { 2,3,4 };

 double dTest3[3] = { 4,8,5 };

 COleSafeArray saRet1;

 COleSafeArray saRet2;

 COleSafeArray saRet3;

 SAFEARRAYBOUND rgsabounds;

 rgsabounds.cElements = 3;

 rgsabounds.lLbound = 0;

 saRet1.CreateOneDim(VT_R8, 3, dTest1);

 saRet2.CreateOneDim(VT_R8, 3, dTest2);

 saRet3.CreateOneDim(VT_R8, 3, dTest3);

 m_chartPtr->DataSourceSettings->DataType->Item[0] = Cfx62::DataType_XValue;

 m_chartPtr->DataSourceSettings->DataType->Item[1] = Cfx62::DataType_Value;

 m_chartPtr->DataSourceSettings->DataType->Item[2] = Cfx62::DataType_Value;

 m_listDataProviderPtr->AddCollection( &saRet1.Detach() );

 m_listDataProviderPtr->AddCollection( &saRet3.Detach() );

 m_listDataProviderPtr->AddCollection( &saRet2.Detach() );

 m_chartPtr->DataSourceSettings->DataSource = 

(IDispatch*)m_listDataProviderPtr;
