The following VB sample applies strikeout font attribute to cells in the second column ( 1 ), if the sum between second and third column ( 2 ) is less than the value in the first column ( 0 ):

With G2antt1.ConditionalFormats.Add("%1+%2<%0")
    .ApplyTo = 1
    .Bold = True
End With

The following C++ sample applies strikeout font attribute to cells in the second column ( 1 ), if the sum between second and third column ( 2 ) is less than the value in the first column ( 0 ):

COleVariant vtEmpty;
CConditionalFormat cf = m_g2antt.GetConditionalFormats().Add( "%1+%2<%0", vtEmpty );
cf.SetBold( TRUE );
cf.SetApplyTo( 1 );

The following VB.NET sample applies strikeout font attribute to cells in the second column ( 1 ), if the sum between second and third column ( 2 ) is less than the value in the first column ( 0 ):

With AxG2antt1.ConditionalFormats.Add("%1+%2<%0")
    .ApplyTo = 1
    .Bold = True
End With

The following C# sample applies strikeout font attribute to cells in the second column ( 1 ), if the sum between second and third column ( 2 ) is less than the value in the first column ( 0 ):

EXG2ANTTLib.ConditionalFormat cf = axG2antt1.ConditionalFormats.Add("%1+%2<%0",null);
cf.Bold = true;
cf.ApplyTo = (EXG2ANTTLib.FormatApplyToEnum)1;

The following VFP sample applies strikeout font attribute to cells in the second column ( 1 ), if the sum between second and third column ( 2 ) is less than the value in the first column ( 0 ):

	.Bold = .t.
