    .Background(exNodeFrame) = &H2000000
End Wit

The following C++ sample changes the frame for all nodes:

#include "Appearance.h"
m_chartview.GetVisualAppearance().Add( 2, COleVariant("D:\\Temp\\ExOrgChart.Help\\node.ebn") );
m_chartview.SetBackground( 0, 0x2000000 );

The following VB.NET sample changes the frame for all nodes:

With AxChartView1
    .VisualAppearance.Add(2, "D:\Temp\ExOrgChart.Help\node.ebn")
    .set_Background(EXORGCHARTLib.BackgroundPartEnum.exNodeFrame, &H2000000)
End With

The following C# sample changes the frame for all nodes:

axChartView1.VisualAppearance.Add(2, "D:\\Temp\\ExOrgChart.Help\\node.ebn");
axChartView1.set_Background(EXORGCHARTLib.BackgroundPartEnum.exNodeFrame, 0x2000000);

The following VFP sample changes the frame for all nodes:

With thisform.ChartView1
