hi,

I need to access the background color and text color of a Pivot/Straight table expression cells

but the code sample for these properties (and few others) is not working

it usues a member that doesnt exist (ExpressionVisuals) and has other errors

can anyone figure out the correct code?

thanks in advance

Mansyno

Hi Mansyno

I suggest that you post the code that is not working so that someone can help you.

Regards

Jonathan

hmm well it is in the API guide .qvw file but anyway here it is

btw i have ver 10. sp3

function Rand (Lo, Hi)

Rand = Lo + Rnd() * (Hi - Lo + 1) - 0.5

end function

sub randpiv

rem ** set random colors in all expression **

rem ** cells in all pivot tables on active sheet. **

Objects = ActiveDocument.ActiveSheet.GetSheetObjects

For i = lBound(Objects) To uBound(Objects)

If Objects(i).GetObjectType = 10 Then 'pivot tables

set Pivot = Objects(i)

set y = Pivot.GetProperties

set e = y.ExpressionVisuals

for k = 0 to e.Count-1

set f = e.Item (k)

set v = f.CellVariations (0)

v.FgColor.Col = RGB(Rand(0, 127), Rand (0, 127), Rand (0, 127))

v.BgColor.Col = RGB(Rand(128,255), Rand (128,255), Rand(128,255))

v.TotalFgColor.Col = RGB(Rand(0, 127), Rand(0,127), Rand(0,127))

v.TotalBgColor.Col = RGB(Rand(128,255), Rand(128,255), Rand(128,255))

y.TableProperties.StyleNumber = -1

Pivot.SetProperties (y)

end if

end sub

I discovered that the posted code is in the API guide for the CellVariations method. It may be in the API guide, but its broken in several ways.

First off - the member name is ExpressionVisual (no 's').

Second - ExpressionVisual is not a member of the properties object returned by GetProperties. The API guide does not document which objects have ExpressionVisual as a member, but the code sample has (adapted to your code):

set y = Pivot.GetProperties

set e = y.Expressions.Item(0).Item(0).Data.ExpressionVisual

Third - ExpressionVisual does not have a Count member. It does have an AttributeExpressions memer which is an array of attribute expressions.

CellVariations and ExpressionVisual are not fully documented in the API guide, so getting them to work will take some experimenting.
